Gather around —  we have some new interesting details about Intel’s Coffee Lake platform — courtesy, new leaked benchmarks shared by the SiSoft Sandra database. Yes, the same database that recently listed a Coffee Lake processor with six cores and 12 threads. You can find the entry over here.


For the uninitiated, Coffee Lake happens to be the codename representing the platform developed by Intel to carry forward the 14nm architecture in Kaby Lake to more than 4 cores for the mainstream sect of the market.

As you can see in the image below, the new entry refers to one Genuine Intel CPU 000 that belongs to the Kaby Lake family and brings a 6 core, 12 thread config. The base clock speed is 3.5 GHz, which is definitely pretty decent for a hexa-core part and 94.97 GFLOPs. It comes with 256kb of L2 cache per core and 9MB of shared L3 cache. The leak also suggests that there will be a variant with 12MB of L3 cache.

Note that both variants are engineering samples and sports a turbo clock north of 4.2 GHz. Given that the IMC is clocked at 2.7GHz, we are looking at DDR4 2700 MHz. The clocks on all final versions are likely to be at least this high, or maybe even higher by a couple of hundred MHz or so.

Meanwhile, the Coffee Lake-S series will come in a couple of different variants — one with 4+2 config (quad core and GT2 graphics) whereas the other is expected to be a 6+2 (hexacore + GT2 graphics).

As for the 4+2 variant, the part will probably have a die size of 126 mm2 whereas that for the 6+2 variant will be 149 mm2 (the same as what we had in the Coffee Lake-X variants).
