Intel Core i7 7800K And 7800 6-Core, 12-Thread Coffee Lake Processor Specs Leak

Intel manufacturing D1X 1
Back in late June, we got out first glimpse at Intel’s upcoming Coffee Lake-based processors. Unlike previous mainstream Intel processors, these Coffee Lake parts came packing six cores and 12 threads. The engineering sample that made its way to SiSoft SANDRA featured a base clock of 3.1GHz, a turbo clock of 4.2GHz, 256KB L2 cache and 9MB L3 cache.

However, a new report is shedding some additional light on at least four upcoming Coffee Lake desktop processors. The first is the alleged Core i7 8700K. The processor is said to have six cores, a base clock of 3.7GHz, 12MB L3 cache and a 95W TDP. Being that this is a “K” part, it will be unlocked, making it suitable for overclockers. There will also be a “plain” Core i7 8700 which will have a base clock of 3.2GHz. Both processors have HyperThreading enabled, meaning that they can handle 12 threads.

Moving down the line, there also appears to be a least two hexa-core Core i5 parts, which include the 8600K and the 8400. The Core i5 8600K reportedly has a base clock of 3.6GHz and 9MB of L3 cache. The Core i5 8400 drops its base clock all the way down to 2.8GHz. TDPs for the two processors are listed at 95W and 65W respectively, while neither chip has HyperThreading enabled. That means those six cores will be backed by just six threads.

Not to be left out, there are scant details on Coffee Lake mobile processors. Intel is reportedly sampling six-core mobile parts that operate at 2GHz with a TDP of 45W. In addition, there is another alleged 2GHz quad-core part that incorporates 6MB L3 cache, HyperThreading, and Intel’s GT3e GPU with a TDP of just 28W.

Intel 10nm Die Area Scaling

Although Coffee Lake is still based on a 14nm manufacturing process, it stands to reason that the extreme maturity of the node is allowing Intel to further refine its power efficiency. Coffee Lake parts on track to ship sometime in 2018.

We also can’t forget that Intel will pushing its Cannon Lake architecture out by Q4 2017 as well. Cannon Lake processors are built in Intel’s new 10nm manufacturing process, with the first chips being relegated to the 15W (U-Series) and 5W (Y-Series) product families.
