Coffee Lake info leaks – a six core i5?

 
At the time of writing Intel are rumoured to be releasing their next-generation mainstream series of CPUs within the next few months under the codename “Coffee Lake”, offering up to 6 cores in a desktop-grade platform and without some of the features of Intel’s new X299 CPUs (like AVX-512 support). 
 
A report from CPCHardware has leaked some new information about Intel’s upcoming Coffee Lake series CPUs, including clock speeds TDPs and core counts for both i7 and i5 series CPUs. 
 
In the high-end Intel will be releasing an i7 8700K CPU, though the name of this product could be changed before launch. This CPU will feature six cores with a base clock of 3.7GHz and Hyper-Threading for 12 total threads. This chip is said to have 12MB of L3 cache and a TDP of 95W. A lower end variant, the i7 8700 is also said to come with a 3.2GHz base clock, which is a huge drop when compared to its K-series variant.   
 
One of the most interesting pieces of information in this report is the existence of a 6-core i5 series CPU, which is set to come with the i5 8600K name and lack Hyper-Threading and come with only 9MB of L3 Cache while maintaining the same 95W TDP. This CPU is said to release with a base clock speed of 3.6GHz and with an unknown boost clock. It also looks like there will be a lower clocked i5 8600 model which will feature a base clock of 2.8GHz, which again is a huge drop when compared to the similarly named K-series model. 

When compared to Kaby Lake these new CPUs will offer lower clock speeds and that is thought to be similar performance per clock, which means that these new CPUs should deliver less single-threaded performance. Even so, these CPUs should easily be able to outperform their last-generation counterparts when their higher core counts come into play.

One important aspect of Intel’s new Coffee Lake CPUs will be their core-to-core interconnection method, as their new Mesh architecture (that is used in Skylake-X) can sometimes limit performance in gaming applications. Will Intel be using a traditional ring bus architecture like their desktop Kaby Lake parts?

Right now, we expect Intel to keep using their Rung Bus architecture with this release, as Mesh is primarily designed for CPUs with higher core counts, specifically for their high core count Xeon CPUs. At this time the move to Mesh is not required for mainstream CPUs, especially given the new architecture’s latency at lower core counts.
