Intel i7-8700K CPU Review Leaks Onto The Web
A new review of a Core i7 8700K has leaked onto the web, in Asia it is EXPreview who posted some benchmarks of the 8700K versus the 7700K and 7800X.
The guys benchmark the proc based on a the default clock / turbo on a system with 4x8GB memory set at JEDEC DDR4-2400 with CL14 timings. The results are as expected and as prognosed from what we have seen earlier on with the Cinebench leaks. EXPreview also took the proc to 4.5GHz and is showing some gaming benchmarks at 1920 x 1080.

Look at that witcher 3 performance increase. Also nice to see that is beats the 7700k across the board, even if it is only by a fraction in some cases.
Besting the 7700k in more singlethreaded tasks where 7700k is at it's best and also having the multithreaded advantage, unlike ryzen which trades single threaded performance for multithreading.
I think this cpu is going to sell like crazy.

I may be misinterpreting the images and please correct me should I be wrong: Since all the videos scores are pretty much equal the 7700K and 8700K seem to be the same in terms of power (frequency, IPC, so to speak) while the increase in FPS, more than anything, seems to be core/thread count related in combination with the given game's engine anyhow.
Meaning, ultimately, what I'm reading from those charts is that a 7700K is in fact a bottleneck due to core/thread count limitations in a lot of cases and likely has been for quite some time - pretty much all of Intel's lineup has been.
Or is it that the new manufacturer process is kicking in, assuming there's no fundamental architecture difference between the 7800X and 8700K? The 7800X feels quite off in terms of numbers and the 8700K seems to turn into a inexplainable wonderchild.
That's quite interesting, to say the least.
Yes, from those tables you can see that the 7700K has bottlenecked a few games, and the 8700K is removing/reducing some of those bottlenecks. The 7800X and 8700K are different architectures, the 7800X has something similar to AMD's Infinity Fabric between the cores which decreases gaming efficiency - I think mainly through increased latency within the CPU itself between the various cores. 8700K is fundamentally the same architecture as the 7700K, which is actually the best architecture for gaming, so only difference is that 8700K is benefitting from 2 more cores - so 8700K is the best gaming CPU at the moment.

I can already hear the sweet cry of anguish from the horde of four cores is forever enough for gaming fanboys. That cry of terror is such pleasant music for weary ears.
It's pretty funny how Intel's one-sided decision to abandon all cooperation with review sites (apart from a couple of cherry-picked, dependent American ones supposedly) also means they have little NDA control. What are they going to do? Not send CPUs they already aren't sending?
