Currently, Intel is launching the new desktop desktop core desktop and the mainstream desktop main response to Ryzen AMD architecture since the platform was launched in March. That's not to say we have not seen some significant changes in Intel's actual desktop-part, even before today's launch, we've seen price declines and feature enhancements from Intel in 2017 rather than at least from any time in 2011.
As we discussed earlier, Core i7-8700K is not a new CPU architecture. It's still based on the same Kaby Lake processor that debuted last January with the Core i7-7700K, which is an architectural version of Skylake that was launched with Core i7-6700K. The new chip is built on the Intel 14nm ++ process, however, which offers a modest increase in frequency and hopefully better power efficiency than the previous 14nm +. The Z370 chipset is similar to the Z270 chipset, with the exception that it supports the new Coffee Lake CPU, while the old Z270 hardware does not. If you are looking for a major architectural update with Coffee Lake, you will be disappointed, but the core clock has appeared despite adding two extra cores.
Intel Six-Core Evolution
At the same time, however, Intel's decision to bring a six-core solution to market is a big deal. For nearly seven years, Intel's six core processors have brought a decent premium. In 2011, Intel released the Core i7-980 and i7-970, which offered a six-core processor on the LGA 1366 form factor and was compatible with the original LGA1366 chipset, but only the Core i7-980 was less than $ 800, and it ran $ 583 at launched. Intel's initial line of six-core post-Westmere chips matches this price. In 2014, Intel introduced the new Haswell-based Core i7-5820K, priced at $ 400, and launched Broadwell-E six cores at $ 434 in May 2016. Skylake-X's current six core cores, the i7-7800X, own an MSRP for $ 389, which puts it right inside the Core i7-8700K brackets.
This development makes the Core i7-8700K look a little pedestrian at first glance, but there are two clear differences between this core and the six core chips that Intel has previously launched. First, the Core i7-8700K has a much higher base and boost clock. The chart below shows how the six lowest / lowest Intel core processors have overlapped, back to 2014 and Haswell-E.
The base clock of 3.7GHz is only about six per cent higher than the 7800X, but the 4.7GHz amplifier frequency generates every other six core chips from the water, including old models not included here from Ivy and Sandy Bridge. While the frequency of all-core increase is below 4.7GHz, so is the case for other six-core chips as well.
The second difference between the 8700K chip and the Intel chip is when Coffee Lake needs a new motherboard, the board itself should be cheaper than the Intel HEDT motherboard. The Intel Z270 motherboard starts at $ 100 in Newegg, while the X299 motherboard that supports the full range of Intel X-Series chips is different from the quad-core variants starting at $ 215. The MSRP on our Asus Prime Z370-A is higher, priced at $ 169.99 , but Asus' HEDT-equivalent, Prime X299-A is the $ 295 board. Either way, it combines cheaper motherboard costs with a lower Core i7-8700K price, and this is Intel's six core platform ever.
AMD: The Fly In Intel’s Ointment
If this launch has taken place in 2016 instead of 2017, this would be an impractical article. The 8700K adds more cores and higher clock speeds. It will obviously blow 7700K out of the water, and while the 7800X features Intel's high-performance Skylake-SP architecture, high clock speeds have their own performance advantages. At the very least, we expect the Core i7-8700K to compete well with Intel's six core HEDT processors, provided that the benchmark is not bandwidth-bound bandwidth.
The AMD Ryzen family made this situation difficult for Intel. First, there is Ryzen 5 1600X, with a 4.1GHz clock boost, six cores, 12 threads, and a new $ 219 price point, though it's unclear whether AMD has cut prices across the board or if the reduction is temporary. Even on the official $ 249 price list, Ryzen 5 1600X packs a serious blow in the $ 219 per-piece category that will be a stronger core. We suspect Intel has chosen a turbo clock for the 8700K that will sweep Ryzen 5 1600X in benchmarks, but the AMD chip is $ 110 to $ 140 cheaper.
Secondly, there is overall sales throughout AMD's Ryzen 7 series. Newegg showed the Ryzen 7 family at a much lower price for at least the next six days. Here's how the current lineup is broken (all prices apply on 10/04/2017):
Whether $ 100 from Ryzen 7 1800X is permanent or not, this is the CPU to watch when facing a multi-threaded game at the top of the market. Sixteen threads versus 12 is still a boost of 1.33x in total thread, and while Intel has an advantage in single-threaded performance, AMD is no longer sitting behind the 8-ball Piledriver, and this takes a somewhat more performance than TPS than Intel does the scenario well. Intel does have an extra ace on its sleeve. Our tests show the Core i7-8700K is much more aggressive when it comes to an all-core turbo clock; chip holds a stable 4.3GHz all-core frequency. That's 1.16x higher than Ryzen 7 1800X or Ryzen 7 1600X. Combined with Intel's known advantages in single-thread processing, and Ryzen CPUs should strive to make a difference.
Test Configuration
We tested all of our systems with 32GB of DDR4-3200 in four sticks of 8GB each, with a GTX 1080 Ti GPU running Nvidia's 384.94 drivers, with an Asus Prime Z370-A motherboard. There are a few things to be aware of as you page through our test results. First, while we've largely standardized on the same benchmark set throughout 2017, we've added three tests recently-a Qt compilation test, PCMark 10, and a separate physics processing test in Blender-that we do not have earlier data for . Instead of omitting these from our test results, we have included them even though the comparative processors have many more cores and threads. Consider these three benchmarks an interesting look at how cores and clock speeds impact apples-to-apples comparison.
Cinebench's single-threaded performance is exactly what we'd expect from a chip that's based on the same architecture as Kaby Lake and Skylake. The 2.5 percent gap between the 7700K and 8700K is small enough to call it a tie, but the multi-threaded results are quite interesting. Intel's Core i7-8700K is 15 percent faster than the Ryzen 5 1600X and within spitting distance of the Core i7-6900K. That's not a result we expected; while Intel's core clocks are much higher on the 8700K compared to the 6900K,we expected the extra cores on the Broadwell-E CPU to count for more than they do. Ryzen 7 holds the overall lead, but the gap between AMD and Intel has shrunk significantly.
Our game benchmarks are listed below, although we must include a somewhat different set of processors than any other testing. The Ryzen 7 1800X, Core i7-6900K, Core i9-7900X, and Core i7-8700K all have very different clock speeds and offer different core configurations, ranging from the "classic" Intel HEDT (represented by 6900K) configuration, the new . Skylake-SP architecture with L2 and L3 smaller (7900X), Intel's latest desktop CPU with high core clock (8700K), and Ryzen AMD family. 1800X is a nice stand-in for 1600X here; Both CPUs are very similar in the 1600X game test. An apology for previous edits that says that all game results are identical - one title, Hitman, shows variations on 1440p.
The AMD Ryzen 7 family is not as strong as 1080p as in 1440p and 4K, but 1080p is, at the moment, a rather artificial test, at least when using GPU as strong as GTX 1080 Ti. While we do not intend to stop it entirely, it is now very useful to measure the performance differences of CPU architectures as new architectures begin their debut. We did a 1080p test round when Ryzen 7 was launched and we will use it again for future architectural changes, but 1440p and 4K better capture where top-class gamers tend to spend money on performance. Despite using various L2 cache configurations, clock speed, and core count, AMD and Intel are well-suited for most game tests (Hitman is an exception, and the 8700K does very well in that test).
Conclusion
AMD has spent the last six months punching holes in Intel's product lineup. While Ryzen 7 and 5 may not have a single-thread performance crown, their relatively high clock speeds and excellent multi-threaded scaling give Intel Kaby Lake and Broadwell-E a serious beat-down. AMD's Threadripper 1950X is still far and away from the fastest chip that you can buy for $ 1,000, even compared to Intel Core i9-7900X. But to this day, there is a new power to be reckoned with in the $ 350 to $ 400 CPU market, and it's Intel blue.The combination of Core i7-8700K with high clock speed and high single-threaded performance allows it to punch well above the weight class. While Ryzen 7 1800X won more tests than lost against 8700K, he won almost all tests with a slim margin. This is not unique to AMD; Intel Core i7-6900K is in the same position. In fact, throughout our test range, the distance between 6900K and 8700K is even narrower than the gap between the latest six Intel cores and Ryzen 7 1800X. Meanwhile, the unfortunate 7700K is completely outclassed with every other CPU in multi-threaded workloads, and the 7700K owner who buys the CPU for multi-threaded workloads may be slightly chopped up with Intel right now, given that their newer motherboards will not pick up a Core i7-8700K. Kaby Lake-X has also been avoided by this CPU, losing whatever marginal utility it may offer. This move never makes any sense, since the Kaby Lake-X CPU can not use the full-featured X299 platform they face, and anyone who glances at one of these systems will see better results with the 8700K figure.
The combination of Intel in the best single-threaded performance in its class and multi-threaded performance is almost as good as making the Core i7-8700K a better choice than the AMD's Ryzen 7 1800X considering the current price for both processors. AMD will have an opportunity to reverse the tables next year, assuming the Ryzen + refresh architecture can achieve higher clock speeds than the first-generation Ryzen processors, but Intel has an overall advantage today.
The news is not all bad for AMD. Ryzen 5 1600X is not as fast as the Core i7-8700K, tends to lag behind it by 20-25 percent, thanks to a small part of the clock gap between two CPUs (3.7GHz to 1600X, 4.3GHz for the 8700K). What 1600X has gone for it is the price. Core i7-8700K is approximately 1.2x faster than 1600X, but it costs 1.44x more expensive before there is a difference in the cost of the motherboard. At a price of $ 219, the chips that are currently listing in Newegg, the comparison is even more tilted - 1.64x more money, with performance around 1.2x to 1.3x more. We still expect 6-core / 12-thread Ryzen 5s to compete well with Intel Core i5, and if you try to maximize performance per dollar, we easily recommend Ryzen 5 1600X through Core i7-8700K. Actually, we would recommend it as the best overall value of AMD offered throughout the Ryzen family.
The desktop CPU market has been more dynamic in the last 10 months, six years earlier, combined, and we're happy to see it. Intel may have recruited the top position in the desktop CPU market, but the Core i7-8700K is as strong as it needs a core that will compete effectively against AMD's top-end Ryzen CPUs. It's no coincidence that Intel suddenly found a way to build a core six-core desktop core processor seven months after AMD Ryzen's family started eating a multi-threaded lunch, just as there was no Pentium core damage down with Hyper-Threading case in January, 10 core CPU costs down for ~ $ 800 in June, and Core i3 and Core i5s are both packed even more today. Intel has delivered an outstanding six-core CPU on the Core i7-8700K, but AMD deserves a nod for forcing them to do so.
