Comet Lake H and S are going to disappoint

GFX CI bootlogs are a bit of a snooze

Intel is set to release its Comet Lake product stack and retire its Coffee Lake architecture but Intel GFX CI bootlogs spotted by @InstLatX64 hint that Comet Lake H (CL-H) and Comet Lake S (CL-S) are a bit of snooze.

CL-H will include an octa-core SKU and a deca-core variant is expected. The octa-core SKU will feature 16 MB of L3 cache and a 2.4 GHz base clock which is similar to the Core i9-9980HK. The bootlog reports the CPU boosting to 4.4 GHz, slower than the Core i9-9880H and Core i9-9980HK. Essentially they look like re-bodied Core i9-9880H or Core i9-9980HK.

The CL-S bootlog said that the Intel GFX CI reports that the hexacore chip supports Hyper-Threading, which Intel currently extends to only its octa-core Coffee Lake S Refresh SKUs. The chip has 12 MB of L3 cache, 2 MB per core, which puts it in line with Hyper-Threaded Coffee Lake S Refresh processors.

This means that Intel is bringing Hyper-Threading lower down its CL-S product stack than it did with Coffee Lake S. The hexacore CL-S processor clocks between 3 GHz and 3.4 GHz which is comparable Coffee Lake S Refresh processors.

All of this is just minor improvements over the Coffee Lake Refresh architecture. Intel will introduce deca-core processors to CL-H and CL-S, which will undoubtedly offer upwards of 25 per cent better multicore performance than octa-core Coffee Lake Refresh chips.
