The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete.

Intel’s Core i7 7740X will beat the 7700K and break the 5GHz barrier
Figures from 100 tested Core i7 7740X chips have surfaced in an X299 motherboard reviewer’s guide, showing the best of the bunch can overclock as high as 5.2GHz. That’s right, it sounds like the CPU can clock even higher than the i9 7900X, and all without popping the lid.
The new breed of CPUs are hitting some impressive speeds, but are they going to end up sitting atop our guide to the best processors for gaming?
A chapter of one manufacturer’s X299 reviewer’s guide is reportedly concerned with the overclocking capabilities of the quad-core, eight-thread Kaby Lake-X chip. After testing 100 i7 7740X samples, the unnamed company discovered the CPUs rocking the most robust silicon could hit 5.0GHz in Cinebench R15 with only 1.205v of core voltage, and can be pushed up to a maximum speed of 5.2GHz.
What do Intel themselves say, though? At E3, we interviewed Frank Soqui, their general manager of enthusiast desktop. Given Intel’s Gregory Bryant heralded them as having ‘ultimate overclocking performance‘, we asked whether the Kaby Lake-X parts would have more overclocking headroom than standard Kaby Lake CPUs, like the 7700K.
“I don’t know that there’s more headroom,” Soqui says. “It’s really process dependent and architecture dependent. We never spec a frequency for overclocking. There’s enough variability in there that we cannot predict the max overclocking frequency.”
But can you get higher clocks out of Kaby Lake-X?
“I would say, in general, that would be a fair guess…” Soqui says with a smile. “There’s no way for us to screen predictably in manufacturing to a specific frequency of overclocking. Even if we did those conditions would be different in a real motherboard situation.”
As we’ve mentioned before, though, the X-series CPUs are going to live up to their predecessor’s reputation for pumping out silly amounts of heat when overclocking. The guide recommends liquid cooling for both Kaby Lake-X and Skylake-X chips whether or not you’re overclocking, which is no surprise: the guide shows the lowest-quality i7 7740X running at up to 87°C.
So, the overclocking potential of these chips is pretty impressive, if toasty. But what the reviewer’s guide doesn’t say is how many of those 100 samples were capable of these overclocking heights. Though, if all the noises from Intel are true, there might actually be a valid reason for the i7 7740X’s existence – with the potential overclocking performance on offer the single-threaded speeds of the Kaby Lake-X could make it the fastest gaming CPU of all the X-series.
But then there’s the matter of the expensive X299 motherboard platform, adding a hefty premium on top of what you’d pay for a 7700K and Z270 board. The Kaby Lake-X chips won’t be able to take advantage of the standard X299 boards’ quad channel memory, and only support 16 PCIe lanes. That means if you shell out for a full-sized X299 board to go with your shiny new chip you’re wasting a great deal of your money. Intel have said motherboard makers can create cut-down X299 boards, but whether any of them will actually bother is still very much an unknown.
In these rapidly changing times, however, do you really want to drop a whole lot of cash on a quad-core CPU? In gaming terms, single-threaded performance is still very much the key spec for now, but for how much longer? With the core-count war now raging between AMD and Intel, game developers are going to start taking advantage of the extra silicon going forward, and that’s going to leave these chips behind.
