It has twelve threads and 28 PCIe lanes, as well as a base clock speed of 3.5 GHz that can go up to 4.0 in Turbo mode.
The Intel Core i9-7900X is the 10 Core, 20 thread replacement to the Core i7-6950X.
Almost a decade ago, Intel (NASDAQ: INTC) introduced a new branding scheme for its personal computer processors - a standard "good, better, best" scheme.
The two Core i7 chips would be Kaby Lake-derived while the rest of the Core i9 family is based on Skylake-X. The total cache on this behemoth is 16.5 MB (L3).
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.
The specifications of the flagship 12-core Core i9-7920X are still unknown but it should pack 16.5MB of L3 cache and will definitely be the fastest Intel Core CPU on the market, judging by the known specifications. Here are the Intel Skylake X Core i9-7920X, Core i9-7900X, Core i9-7820X, and Core i9-7800X Mega-Tasking CPUs leaked.
It seems the war clouds are gathering and a showdown between Intel and AMD is imminent. In the past, a raw number of cores hasn't corresponded well to usable power, but AMD's latest generation of Ryzen CPUs have offered great performance at a price much lower than what Intel can now charge.
Experts though opine that the Skylake X chips would be positioned in the same segment as the Intel HEDT (high-end desktop) range did in the past. Increasing the L2 cache by 768KB doesn't automatically compensate for shrinking the L3 cache. If you want to run two graphics cards at full x16, you have to buy a 10-core chip to do it. Currently, the Core i7-6850K supports 40 PCI-Express lanes with an MSRP of $617 - $628.
According to WCCF Tech, the Intel Skylake X Core i9-7920X processor is a juggernaut featuring a total of 12 cores and 24 threads. Unless Intel plans a serious price cut at this core count, enthusiasts will have to pay top dollar for a 32-lane solution. This unit, however, will have a base clock rate of 4.3 GHz and it will make a 0.2 GHz jump when user step on the Turbo 2.0.
Along with these, there are Core i7 processors in the line.
The average, relatively uninformed computer buyer (e.g., most computer buyers) will see that a system powered by a Core i7-7700K is a Core i7-based computer and that the Core i7-6900K-based machine also has a Core i7.
