First off, this is going to become quite confusing for people less familiar with computer hardware. Intel has Z270, AMD has X370, and now Intel is going to have X299, and AMD is going to have X399/X390. But I digress.
X299 is a bit interesting as it’s going to have two separate ranges of CPU’s: Skylake-X and Kaby Lake-X.
Honestly the less interesting of the two, Kaby Lake-X will be limited to 4 cores and 8 threads, so basically you’re not getting an improvement over the standard Kaby Lake platform. In fact, it’s limited to 16 PCIe lanes and dual-channel memory, so besides maybe some extra USB and SATA ports versus the Z270 platform, I really don’t see what purpose Kaby Lake-X has. Maybe it’ll just have more power available to it for more stable overclocks? I’m not really sure.
Skylake-X, on the other hand, will be the next HEDT platform, and will now be expanded to include the first consumer 12 core, 24 thread CPU. It’ll also feature up to 44 PCIe lanes and quad-channel memory.
Of course the big question is price. I’d expect that the Kaby Lake-X chips would start around $350, because otherwise if they’re more expensive you might as well just get a 7700K. As for Skylake-X, who knows?
Taking past specs and pricing into account, I’d maybe expect the 7800K to be a 6-core for around $400, the 7850K to be an 8-core for around $600-$650, the 7900K to be a 10-core for around $1,000 and the 7950X to be a 12-core for around $1,700, following the 6000-series pricing.
Of course, Ryzen may convince Intel to drop their prices, considering that the 1700X and 1800X can obtain comparable performance to a 6900K for less than half the price. In that case, the prospective 7850K may drop to only around $500 to compete with the 1800X, but I honestly expect the 7900K and 7950X to stay at high pricing just because that’s what Intel has always done with their ultra-high end products. Although if AMD comes out with 10 or 12-core options on their X390/X399 platform that may influence Intel to drop the prices of those as well.
The high-end desktop market looks set for a massive showdown this summer between Intel and AMD. The former is set to release its new X299 platform and the latest rumors point at up to six Core i9 and Core i7 CPUs sporting up to 12 cores as it looks set to replace its current X99 platform
AMD on the other hand had already shown part of its hand, by announcing Threadripper – an entirely new range of CPUs based on its Zen microarchitecture that will sit above the Ryzen 7 series. These will have up to 16 cores and if current rumors are anything to go by, AMD is planning a top to bottom range with nine CPUs with 10, 12, 14 and 16 cores.
Traditionally, these high-end desktop platforms are used as workstations and for multi-threaded performance but do have the benefit of supporting multiple GPUs with extra bandwidth too for high-resolution gaming. This could mean that Intel will have a real fight on its hands with AMD already offering excellent value in multi-threaded applications with its Ryzen CPUs, which have offered similar performance to Intel but for much lower costs.
One area AMD has struggled is with low-resolution gaming, but that’s not likely to be a target for owners of high-end desktop systems so Threadripper could be even more disruptive here than Ryzen was in the mid-range.
Several websites have leaked data regarding the new CPU ranges and you can see all the supposed new CPUs listed below. Hexus pointed at a post on Anandtech that claims to list the entire Skylake-X or Core i9 CPU line-up. Meanwhile Wccftech cites https://en.wikichip.org as the source for its list of Threadripper 10, 12, 14 and 16-core CPUs from AMD.
All information is unconfirmed at this point so take it with a generous pinch of salt.
