Core i7-8700K Review: Intel’s response to Ryzen is faster and cheaper than ever - fernandezyesett

Intel's 6-core 8th generation Core i7-8700K CPU is the reality check to high schoo-carrying into action, high-priced CPUs like the $2,000 Sum i9 and $1,000 AMD Ryzen Threadripper. The real battle for the desktop and consumer's wallets is with this astonishingly affordable (for Intel anyway) $359 Central processor, code-called Chocolate Lake.

In fact, the Core i7-8700K is Intel's first factual response to AMD's discovery series of Ryzen 5 and Ryzen 7 CPUs, and a viable alternative to the Zen-based CPUs. But just how fast is it, and which CPU should you buy? Read on to find out.

Core i7-8700K Coffee Lake — Intel's young Coffee Lake Core i7-8700K is a serious cup of joe for those into performance.

What is Coffee Lake?

Moore's Police isn't exsanguine, but the ability to shrink CPU circuits and gain density has drastically slowed downwardly. Coffee berry Lake, for example, is based along the aforesaid 14nm process the company introduced with its Broadwell line of laptops CPUs in 2014. Since and then, Intel has victimised the 14nm process on Skylake, Kaby Lake, and now Coffee Lake.

Scorn the similar process, however, Intel says it's successful enough improvements along the way to call Coffee Lake a "14nm asset plus" chip. A simpler way is to consider of Coffee Lake atomic number 3 an improved 7th-generation Kaby Lake chip with two more cores, though there are some subtler changes.

So yes, cynics, the but true "8th-generational" part may be the name itself. Folks of a Thomas More forgiving mindset will see 8th-gen chips American Samoa a big breakthrough for Intel, which has offered quad-core CPUs as luxury models exclusively for the endmost ten years. Consider that Intel at one time charged $1,000 for 6-core CPUs. With Coffee Lake, you're acquiring two more cores for the virtually the same price as Kaby Lake and Skylake.

Intel Coffee Lake 8th gen speeds and feeds — Here's the full line up of "8th generation" CPUs from Intel.

Why Coffee Lake requires a new motherboard

Although Coffee tree Lake is essentially an improved Kaby Lake CPU, few key changes bequeath drive Intel fans simply batty. The main one is its incompatibility with older motherboards, despite using the claim Lapp corporal LGA1151 socket.

Why, Intel, why? The company cites several changes. The first is official support for DDR4/2666 instead of of DDR4/2400. The higher-clocked RAM required more tightly controlled layout of the wires operating theater "traces" on the motherboard, which mandated bran-new designs.

Coffee Lake also adopts the nifty "per core" overclocking first introduced with the Core i7-6950X Broadwell-E. This allows a user to overclock just person cores based on the workload.

All this added up to the Z370 chipset you'll bump on new motherboards, the company said. One thing that International Relations and Security Network't clear, however, is wherefore Z370 won't work with older CPUs. Because some the Z270 and Z370 practice the same socket and pretty much the Lapplander chipset pinout, why can't you put your older 7th-gen Kaby Lake into a newer Coffee Lake Z370 mobo? All Intel would articulate is its circuit board partners actually requested a clean go from the past with the new chipset.

How we tested

For this review, we looked at the top cow dung of the lineup: the Core i7-8700K. We compared it primarily to its nemesis: AMD's Ryzen 7 1700X. Although technically priced at $399, we easily found the chip for $359 at Amazon.com or even cheaper when on sales event.

Our original review of the Ryzen 7 was convergent on the whirligig CPU, the Ryzen 7 1800X, but a band has changed since Marching. So we took our original Asus Crosshair VI Champion ramp up, updated to the latest available BIOS, installed a fresh copy of Windows 10, and the latest AMD drivers and Ryzen power plan.

We also changed unstylish the RAM. Our freehanded Ryzen test occupied all slots with DDR4 RAM, which limited the storage speed to JEDEC stock DDR4/2133 (a limitation of Ryzen at the time). For the Coffee Lake showdown, we dropped in 16GB of DDR4/3200 instead, to return the Ryzen 7 chip every chance to shine. If you don't follow current events, you should know Ryzen's memory controller and Eternity Fabric have a selfsame close human relationship, and the higher-clocked the memory board you use, the higher the carrying into action potential.

For GPU we again used a Founders Edition GeForce GTX 1080 card, updated with the latest Nvidia drivers.

On the Intel lateral, we ill-used a GB Aorus Gaming 7 board with a matching Founders Edition GeForce GTX 1080 card, a clean install of Windows 10, and the same fashion mode of Jamaican capita SATA SSD for the primary charge drive.

For Ram, we initially secondhand a matching put over of 16GB DDR4/3200 from our Ryzen build. When calibrating our scheme against Book of Numbers provided by Intel, we base the system really performed slower when selecting the XMP visibility for 3,200MHz. In the death, we swapped in some other pair of modules rated at 2,400MHz and got closer to the numbers Intel said we should expect.

Center i7-8700K Application Performance

To apprehend into the carrying into action characteristics of Core i7-8700K, we ran the CPU done a gauntlet of rendering, encoding, and other productiveness tests. If you utilise mostly Agency applications, a web browser and gambling, our single-threaded performance results matter more. If you delete television or perform early CPU-intensive tasks happening your PC, pay closer attention to the multi-threaded performance.

Cinebench R15 operation

Our initiative test is Maxon's Cinebench R15. It's a popular, escaped benchmark based on the said engine put-upon in the company's occupational group Cinema 4D course of study. Professional 3D rendering tends to like CPU cores and threads, and the default setting for Cinebench exploits all available cores.

The multithreaded results acquit this down, arsenic the CPUs we've tested sort out settled along the thread count. In the strange range, we rich person Intel's Sum i9 chips and AMD's Threadripper. From in that respect the list sorts out nicely settled on the number of cores and whether the CPUs take up Symmetric Multithreading (SMT), or what Intel calls Hyper-Threading.

core i7 8700k cinebench r15 nt — The Cinebench R15 puts the 6-gist Kernel i7-8700K between the 8-core and 6-core.

In multi-threaded tests, the inexperienced Core i7-8700K (the second orange bar in the chart above) straddles the line between the execution of a 6-core CPU and an 8-core CPU. In Cinebench, which scales very asymptomatic with the number of cores, IT comes selfsame at hand to the performance of an 8-burden. The Ryzen 7 1700X easily walks away from the Gist i7-8700K, but if you take any doubts as to whether Nub i7-8700K is amend left to contend with AMD's 6-core Ryzen 5 chips, the result above should answer that.

We also scarper Cinebench in single-rib mode to measure the operation of a Central processing unit when an app or game merely uses one Congress of Racial Equality. For the virtually partly, much a trial favors CPUs with higher clock speeds and greater efficiency. With Core i7-8700K (take in the pink relegate below), you get that in spades, Black Maria, clubs, and diamonds.

core i7 8700k cinebench r15 1t — For single-threaded tasks, the Core i7-8700K squeaks away the Core i7-7700K CPU to win the day.

With a boost clock of 4.7GHz, the Core i7-8700K slides past the previous pinch dog, the Core i7-7700K which has a teetotum boost clock of 4.5GHz. Intel actually dominates the single-threaded functioning with 8th-gen, Kaby Lake and Skylake-X lining up in an orderly style ahead of the pack of older Intel CPUs and AMD's chips.

AMD fans will protest that single-threaded performance doesn't matter in a multi-threaded world, just the harsh truth is a huge swath of applications and games don't exploit more than one CPU core at a time. Despite taking a backseat to Ryzen 7 1700X in the multi-threading test, Core i7-8700K wins this one in a big, big way.

Blender Performance

Our second test is other 3D render app called Blender. It's an open-source, free covering that sees heavy use in many independent movies. Like Cinebench, information technology favors more cores and more threads, but we've found that it doesn't always scale that well with core weigh.

Blender's performance can deviate greatly with the workload thrown at it. For our mental testing, we use the free BMW CPU examination. The result (see the navy-blue BAR midmost of the chart, below) shows the sheer strength of this spunky littler 6-core Coffee berry Lake chip, which isn't content to slum IT with the 6-core Ryzen 5 and Core i7 Broadwell-E fleck. Its score, in fact, is dead straight-grained with the 8-core Ryzen 7 1700X. A 6-core chip that can advert with the 8-core chips is something to Be respected.

core i7 8700k blender 2.78b — The Coffee Lake Mainframe in reality ties with the Ryzen 7 1700X therein multi-threaded Blender trial, despite having quaternity fewer threads than the AMD Processor.

POV-Radiate Carrying out

The Persistence of Vision Raytracer (POV-Shaft of light) is a ray tracer that dates back to the days of the Commodore Amiga. Like Blender and Cinebench, it generally favors efficient CPU cores. Once once more we see the 6-core Heart i7-8700K (the second orange bar, below) hanging closer to the 8-core CPUs than the 6-core chips using the internal bench mark.

core i7 8700k pov ray 3.7 nt performance — Again, the 6-core Core i7-8700K really punches in a higher place its class.

We also run POV-Ray's internal single-threaded test. No surprise, the top-clocked Core i7-8700K (undemanding blue, below) and Core i7-7700K (light pink, down the stairs) are in a dead oestrus. The lineup reinforces Intel's lead in single-rib apps, conscionable as we saw in Cinebench. The first AMD Central processing unit straggles in at 9th place. If you're wondering why the Ryzen 7 1700X really loses to the cheaper 6-core Ryzen 5 1600X, it's likely attributable the slightly high clock speeds of the budget 6-nitty-gritty chip.

core i7 8700k pov ray 3.7 1t performance — Wow: POV Ray's single-threaded version bench mark puts the 6-core CPU moral alongside the quadriceps femoris-core Core i7-7700K.

Corona Renderer

Our unalterable 3D rendering test is within reason new to us and actually came to our attention through and through AMD. Our try set is smaller, but it again shows the Ryzen 7 1700X good hind end't shake the Core i7-8700K (the blue bar at the bottom). The Ryzen 7 wins—but by an uncomfortably slim margin considering it packs four more threads than the Core i7-8700K.

Handbrake Write in code

The world ISN't all about rendering 3D models, of course. More the great unwashe are likely to be encryption video instead, which is where the free and popular Handbrake encoder comes in. For this test, we expend an older version and convert a 30GB, 1080p MKV file using the Mechanical man Tablet preset. Handbrake tends to favor CPUs with Sir Thomas More cores and threads, and we take care that familiar pattern: Gist i7-8700K (the sec orange bar, below) dangling right there with the 8-core CPUs, rather than with the 6-heart chips. It's not enough to outpace the 8-core Ryzen chips surgery the the 8-core Broadwell-E, simply it's nigher than you'd expect.

core i7 8700k handbrake encode — Our Handbrake Encode shows the Core i7-8700K guardianship pace with the 8-core CPUs rather than with the 6-nucleus chips.

Adobe First Imaginative Cloud 2017

Our next picture test uses Adobe's professional Premiere Creative Cloud 2017 to encode an actual video project shot by our television gang in 4K connected a Sony Important camera.

For this trial, we keep the video project on a Plextor PCIe SSD and write the project to the synoptical twist, systematic to remove storage variability from the test.

We use Premiere to encode it using the Blu-shaft of light preset and select the Maximum Picture quality pick, which ups the mental image superior when changing settlement (which we as wel do.) We specify that Premiere use the CPU for encryption rather than the GPU.

Some picture professionals wish scoff at victimisation much slower CPUs for a video job, but image-quality snobs will argue that the scoop result is achieved using the CPU.

core i7 8700k premiere cc cpu encode — The 6-core Deep brown Lake chip shot hangs with the 8-core chips in our Central processor-central video encoding test.

The results again pose the 6-core Core i7-8700K in the linear with the 8-core chips. But we soundless discover those video pros tsk-tsking our choice of CPU encoding, so we also ran our test using the GeForce GTX 1080 for CUDA-based encoding. Though some believe the C.P.U. makes no difference, it's clear that core count still matters even on a GPU encode. It's also shiny the Core i7-8700K pot hang with those 8-core CPUs.

core i7 8700k premiere cc gpu encode — Despite organism sportsmanlike a 6-core CPU, the Core i7-8700K hangs impermissible with the 8-core CPUs for GPU-founded encoding.

Core i7-8700K Gaming Performance

For our Threadripper and Core i9 tests, we didn't linger over gaming performance. Although pivotal, those World Health Organization buy $1,000 and $2,000 CPUs deman them for rendering and encoding, not gaming.

When you're talking about $360 mainstream chips (albeit higher-end mainstream chips), play matters a mint more. Because we wanted to practice the very latest GeForce drivers connected our tests, we too unfree our results to the Ryzen 7 1700X and Core i7-8700K, atomic number 3 we don't have every unwedded CPU along immortalize using the newest GPU drivers.

3DMark Time Spy Performance

Our first test is Futuremark's 3DMark Time Spy test. Futuremark knows how to create attractive test scenes, and Time Spy doesn't let us down. For this test, we disc Time Spy's CPU score, which obviously focuses on the CPU kind of than the GPU. Time Spy also favors Thomas More cores, good news for AMD, whose 8-core Ryzen 7 1700X lands a nose in front.

core i7 8700k 3dmark time spy 1.0 — 3DMark's Time Spy 1.0 CPU screen gives the advantage to the 8-essence Ryzen 7 1700X over the 6-core Core i7-8700K CPU.

Intervening-earth: Shadows of Mordor

The thing is, Metre Spy uses DirectX 12, and the new API's ability to use more CPU cores. Many games woefully just don't manage that practically about having an 8-core group CPU. For example, we use Middle-earth: Shadows of Mordor with the high-resolving texture pack loaded to look at the substantial-world gambling performance of the two chips. That decent lead Ryzen 7 1700X had in Clock time Spy 1.0 evaporates, putting the Core i7-8700K slightly ahead quite than slightly behind when the gritty is set to Radical.

core i7 8700k shadows of mordor 19x10 ultra — Ticking the game quality capable Ultra makes most games GPU loads and the higher clock speeds of Core i7 just don't matter that much against the Ryzen 7 chip.

To get a healthier feel for what would happen if the graphics card weren't the limit on performance, we also ran Shadows of Mordor using the High setting or else of Extremist. No surprisal, the result favors the Center i7-8700K's higher clock amphetamine and greater efficiency and you can see the performance gap open up a trifle more.

core i7 8700k shadows of mordor 19x10 high — Using the High preset, the Nucleus i7-8700K is fitting slightly ahead the Ryzen 7 1700X in Middle-earth: Shadows of Mordor.

Rise of the Tomb Raider Performance

We also ran Rise of the Tomb Raider at 1920×1080 resolution connected the highest image quality predetermined, in DirectX 11 modality rather than DirectX 12. The Core i7-8700K just runs away with information technology Hera. If you recollect this is DirectX 11's fault, we also ran information technology in DirectX 12 modal value, which in reality pushed the Core i7 smooth further ahead.

Take care you, Rise of the Tomb Raider recently received a patch that really improves its performance on the spick-and-span Ryzen CPUs. This is likely just the solid time speed vantage that puts Inwardness i7 before.

core i7 8700k rise of the tomb raider 19x10 dx11 very high — Spouting *Rise of the Tomb Spoiler* at its medium setting and placing more of a burden along the CPU, the Core i7-8700K is well ahead of the Ryzen 7 1700X chip.

Tom Clancy's Rainbow Six Siege

Like Rise of the Tomb Raider, Tom Clancy's Rainbow Six Siege also agrees that the clock speed advantage Core i7 has o'er Ryzen 7 puts it in front.

core i7 8700k rise of the rainbow six siege 19x10 medium — *Rainbow Sixer Siege* at medium heavily favors the Core i7 CPU over Ryzen 7.

As with most games, though, once you increase the image quality slider to higher settings, IT turns into a GPU test. On Rainbow Six Siege, for example, Marrow i7 wins, but it's pretty even.

core i7 8700k rise of the rainbow six siege 19x10 ultra — In Tom Clancy's Rainbow Six Siege at Ultra, the Core i7 Deep brown Lake CPU maintains its leave, but not by much.

Deus Ex Shared

The bad news for Ryzen 7 come from Deus Ex: Mankind Divided. This particular proposition game is one of the few AMD initially known atomic number 3 running improve on Ryzen. With the resolution at 1920×1080 and the High planned, though, Ryzen 7 just can't beat that high clock speed. Core i7 runs away with it.

core i7 8700k deus ex mankind divided dx 12 19x10 high — Connected game loads that aren't constrained by the GPU, the higher clock speed and IPC of the Core i7-8700K Coffee tree Lake CPU lands it well in the lead of the Ryzen 7 CPU.

The reality is, virtually people with beefy GPUs wear't tend to play at High or Medium settings, they pick Ultra. Once you get along that (and it becomes more or so the GPU), it really doesn't matter that much does IT?

core i7 8700k deus ex mankind divided dx 12 19x10 ultra — Most games multitude play will be bottlenecked by the GPU, not the CPU, so Ryzen owners put on't have to sweat it excessively much.

Ashes of the Singularity: Escalation

Our last test is Stardock's Ashes of the Singularity: Escalation. Successful by Oxide A a showcase for the capability of DirectX 12, we ran the game at 1920×1080 using the Crazy predetermined. You might opt this to pull through a GPU test, but Oxide has coded in a benchmark to stress the CPU more the GPU. When we select Central processing unit Focused, Ryzen 7 and its 8 cores hail stunned ahead of the 6 cores in Core i7. Still, this is very much the exception. For the most part, the high time speeds of Core i7 will put it well ahead of Ryzen 7 in most games. Enough to care about or to matter? Probably not.

Core scaling

Before we airless this up, we'll hitting you with two more charts. The first is Cinebench R15, but with the workload plant by hand down to head for the hills from single-core to 16-cores. If you look at the results, you put up see the strengths of either $360 CPU. For the nearly part, Center i7 (orange bars) has the advantage until we get to about 12 threads in Cinebench. That's no surprise A it is a 6-core CPU versus an 8-core Central processor.

core i7 8700k vs ryzen 7 1700x cinebench r15 scaling — The Kernel i7 and its higher clock speed and greater IPC lumps up the Ryzen 7 until you put enough of a load thereon that the deuce extra cores in the AMD CPU hand out an advantage.

One thing our chart doesn't show well, because of the scale, is just how overmuch of an advantage the Core i7-8700K has in those lightly threaded tasks. So we crunched the numbers to find the percent difference the Core i7-8700K has concluded or under the Ryzen 7 1700X.

The results speak pretty distinctly of the advantage Core i7-8700K has up to about 6 duds. Much of that, we believe, comes from the clock speed advantage. We as wel looked at the reported clock speeds of the CPU during these tests and found that while the Ryzen 7 1700X clocked up to 3.9GHz happening single-threaded most of the clip, it was seemingly barred in at 3.5GHz. The Core i7-8700K, on the early hand, would hit 4.7GHz before slowly settling down to 4.5GHz to 4.3GHz across the workloads. That's just a large clock focal ratio disparity, and it shows.

core i7 8700k vs ryzen 7 1700x cinebench r15 scaling percentage — This chart shows how often of huge reward the Core i7-8700K has concluded the Ryzen 7 1700X in lightly threaded tasks. Erst you get to heavier thread rafts, the 8-core Ryzen 7 pulls ahead.

Closing

Ultimately how we judge the Core i7-8700K ($370 on Virago) comes down to two areas: Performance and price.

In public presentation, it's beautiful broad Core i7-8700K is an impressive Mainframe. With its high time speeds and efficient micro-architecture, IT punches dead of its weight class and can competitor CPUs with two more cores. That high clock also aids IT in the very important lonesome-and thinly-rib workloads that the vast majority of consumers rely on day-to-day.

In many ways, the Java Lake Core i7-8700K goes a long toward addressing a key weakness of Intel's previous mainstream standard bearer—the Core i7-7700K.

While fast in single- and light-threaded tasks, the space-core Kaby Lake would lose to the 8-core Ryzen CPUs in heavier-responsibility tasks. The Core i7-8700K doesn't quite ace the comparable AMD CPUs in totally heavy-tariff workplace, but it comes uncomfortably close in a great deal of them and pot even compeer IT in a few.

When Intel finally discharged its 18-center Core i9-7980X and 16-core Meat i9-7960X, the company took back the performance crown from AMD's Threadripper. Still, few took Intel seriously because the pricing on the CPUs was indeed over-the-top, it was clear Intel didn't program to sell many.

It's clear with Coffee Lake, Intel really wants to sell them. At $360 tilt, it compares very favorably to the AMD Ryzen 7 1700X, which has a leaning price of $400 but can be had for $300 to $360.

As skeptical we were at the start of how Intel's 6-core CPU could go toe-to-toe with AMD's 8-core chips, the tests show Coffee Lake is a lot more private-enterprise than we foreseen and a dish out more low-priced than ever before from Intel.

Here's what to corrupt

Pick Core i7-8700K over Ryzen 7 1700X if you mostly play games, effort Office and a web browser, and don't intend to push only content creation apps. Fundamentally, it's the Mainframe for most people who want more performance but don't really do video redaction all the time.

Pick Ryzen 7 1700X over Core i7-8700K if you're looking for a budget content creation machine without stepping up to a Threadripper part. As fast as Core i7-8700K is, most mass who do 3D modelling wish generally want to a greater extent cores, and Ryzen 7 1700X has the reward there. That advantage, however, is a beautiful damned tiny in very much of tests, and something AMD and its fans may lose a lot of stay over.

Choice Congress of Racial Equality i7-7700K over Nucleus i7-8700K if you need an immediate feel of remorse. With the same basic list cost 'tween the two chips (Coffee Lake is $10 more) there's almost no grounds to opt a Core i7-7700K over Core i7-8700K, always. Core i7-8700K can do everything Kaby Lake can do on light tasks, then springiness the 8-kernel Ryzen chips a insensitive time, too. The only possible reason we could see to buy Nitty-gritty i7-7700K is a super-good Mary Leontyne Pric (it'll nonmoving embody sold-out, we're told) or the motherboard you give sensible North Korean won't work with Core i7-8700K. But yeah, simply don't.
