Intel to launch Core i9 Skylake-X & i7 Kaby Lake-X CPUs

Posted May 17, 2017

We've been hearing a few rumors on Intel's next-gen Core i9 family of processors, but now we have benchmarks of the new Core i9-7920X which rocks a 12C/24T design.

The i7-7640X will be a quad-core processor with four threads, 6 MB of onboard L3 cache memory, 16 PCIe lanes, and dual DDR4-2666 RAM. The 7800X chip has a 3.5 GHz base clock with a 4.0 GHz boost clock, with an 8.25 MB L3 cache and 28 PCIe lanes.

I put all of the scores into one of our benchmark templates, so you can see the scores in a much easier to understand way.

Core i7-7740K: 4 cores, 8 threads, 4.3GHz base, 4.5GHz Turbo, no Turbo Boost 3.0, 8MB L3, 16 lanes of PCIe 3.0. Its base clock speed is 4 GHz while there would be 6MB of L3 cache. It was only a matter of time until Chipzilla retaliated, and a leaked slide from a German presentation suggests that Intel is stepping up its own Skylake-X HEDT (High End DeskTop) platforms. Although there is no news about the pricing of these chipsets, Intel is expected to keep the prices competitive considering the stiff competition from Ryzen. Here are the Intel Skylake X Core i9-7920X, Core i9-7900X, Core i9-7820X, and Core i9-7800X Mega-Tasking CPUs leaked.

Here is what Intel's leaked internal document revealed of the forthcoming high-end chips.

To be perfectly frank, it's really about time that Intel introduced the Core i9 branding. Increasing cache sizes without negatively impacting cache latency is a significant undertaking; Intel would have had to do a fundamental respin on Skylake to make this change. And how effective (and how large) various caches need to be for optimal performance is partially a function of the cache architecture. If you want to run two graphics cards at full x16, you have to buy a 10-core chip to do it. It would not be a surprise if Intel tags with a list price of more than $1,000. Unless Intel plans a serious price cut at this core count, enthusiasts will have to pay top dollar for a 32-lane solution. It is also believed to be making its way later in August this year, though the rest of the i9 models are expected to be coming out in June. On the other hand, the Kaby Lake-X family will have two processors - Core i7-7740K and Core i7-7640K.

The new CPUs, whatever specifications they eventually turn out to offer, will be up against stiff competition from AMD's newly announced Ryzen range, which have boasted performance competitive with Intel on multi-core and multi-threaded applications.

Along with these, there are Core i7 processors in the line.
