The new Kaby Lake platform is set to release in 2017, and will feature the same 14nm manufacturing process seen in Intel’s existing Skylake lineup. But unintentionally, Intel’s next flagship CPU, the Intel Core i7-7700K has had certain hardware specifications leaked when what’s thought to be an engineering sample was used on the SiSoft Sandra benchmarking suite.
The Core i7-7700K is a quad-core chip with a base clock of 3.6GHz, and will climb to 4.2Ghz with Turbo Boost. It features the same 8MB of L3 cache seen in previous Core i7 desktop CPUs and 256KB of L2 Cache. The integrated graphics is a 24 EU configuration clocked at 1,150MHz, if Intel revise their graphics silicon, we may see a performance improvement but otherwise we are not expecting much on this front.
It’s not a huge step up in terms of performance unless they can perform some miracles in terms of IPC, but what we do expect is that with Intel’s focus on power efficiency, the new Core i7-7700K will have a lower thermal output and perhaps overclock much better too. This is probably an engineering sample however, so take everything with a pinch of salt.
