Intel’s 6C/12T Coffee Lake Specs Leaked – 4.2GHz Clock Speed, 81W TDP

Intel’s alleged 6C/12T Coffee Lake CPU has suddenly showed up on SiSoft Sandra’s benchmarking database, providing interesting spec info.

Intel’s 8th generation Core processors, code named Coffee Lake, are scheduled to arrive in the second half of this year. The new lineup will see the introduction of the company’s first 6-core mainstream CPUs that will counter AMD’s widely popular Ryzen 5 chips.

Recently, a Coffee Lake 6-core variant appeared in the SiSoft database showing the CPU will support up to 12 threads. The chip will run at a base clock of 3.1GHz and a boost clock of 4.2GHz, with a TDP rating of 81.2W.

The new 6C/12T Coffee Lake CPU will feature a memory frequency of 2700MHz (should be DDR4-2666 memory), L2 cache of 256KB per core and a total L3 cache of 12MB.

For comparison, the Coffee Lake 6-core, 6-thread CPU, which leaked earlier, features a clock speed of 3.5GHz, L2 cache of 256KB and L3 cache cut to 9MB.

As always, we’d advise you to take this information with a pinch of salt as there is nothing official yet.

Intel Coffee Lake to arrive as soon as August

According to a previous Intel roadmap, the first Coffee Lake chips will launch in August. These will come in the form Coffee Lake-S, including the 4-core and 6-core K-series desktop parts. The Coffee Lake chips will also bring Intel’s new Z370 chipset.

More Coffee Lake-S chips will follow in early 2018. These will include 2-, 4- and 6-core parts with TDP ratings of 35, 65 and 95 watts.

Intel Coffee Lake will be based on the same architecture as the current Kaby Lake chips, but will utilize a more refined 14nm++ FinFET process. This should boost clock speeds resulting in an overall better performance per watt compared to last-gen chips.

What do you think of Intel’s 6C/12T Coffee Lake CPU? Could it compete against AMD’s Ryzen 5 in the mainstream desktop market?
