We started hearing concrete details on Intel's new 10th-gen Comet Lake family of CPUs in July 2019, with the flagship Core i9-10900KF rocking 10C/20T @ 5.2GHz, but now we have more information and a new 400-series chipset and LGA 1200 socket teased.
Intel will reportedly be using a refined 14nm+++ node for the new 10th gen Comet Lake CPUs, with the initial launch consisting of 9 different SKUs with many others dropping post-launch. We should expect everything from the low-end Celeron and Pentium CPUs through to Core i3, Core i5, Core i7, Core i9, and Xeon W variants of Comet Lake.
Intel is expecting somewhere around 18% performance improvements in multi-threaded compute workloads, and an 8% generational improvement in normal Windows tasks over the 9th gen parts on the market.
We are to expect the flagship Core i9-10900K with 10C/20T and a boost clock that should exceed 5.1GHz, with 20MB of cache. The Core i9-10900 will have the same 10C/20T with a base CPU clock of 3GHz and boost CPU clock of 5.1GHz -- at just 65W. We should expect the K variant to bump that up a little.
There will also be a new Core i7-10700K that will have 8C/16T with no clock speeds just yet, while the non-K variant in the Core i7-10700 will have 8C/16T at 4.8GHz on 65W. Below that is the Core i5-10500K with 6C/12T and no CPU clock speed details yet, while the non-K version is clocked at 4.3GHz.
