Next Gen Core i5 Desktop Processor Confirmed to Feature HyperThreading
A 3DMark results database entry confirmed that the 10th generation Core i5 desktop processor will indeed feature HyperThreading (HTT). Based on the 14 nm "Comet Lake" silicon, the next-gen Core i5 processor will be 6-core/12-thread. Besides HTT, the processors will feature higher clock-speeds than their 9th generation counterparts. In the 3DMark validation, a Core i5-10600 processor is referenced, featuring 6 cores and 12 logical processors. The chip has a nominal clock-speed of 3.30 GHz in its name string (a 200 MHz increment over the i5-9600), although its Turbo Boost frequency hasn't been detected properly by SystemInfo.
It's possible that the maximum Turbo Boost will be a similar 100-200 MHz gain over the 4.60 GHz of the i5-9600. It remains to be seen what L3 cache amount Intel gives these chips. The 6-core/12-thread Core i7-8700 has 12 MB, or an additional 512 KB L3 slice per core, to cope with the HTT overhead, although there have been exceptions to this rule in the company's mobile processor lineup. Intel is expected to debut its 10th generation Core "Comet Lake" processor series alongside the Z490 Express chipset in April 2020.

I think its time to update caches to L5, (L4 was buffer for iGPU or something like that).
Or increase sizes of L1 and L2
But I think it's about time with some larger cache improvements. While cache sizes have remained fairly stable for Intel, both Haswell and Skylake greatly improved cache bandwidth. Skylake SP/X also changed L3 to make it non-inclusive, in contrast with other (consumer) Intel models which still contain a duplication of L2 in L3, just in case another core needs it, which is "rare". This improvement will not reach Intel's mainstream models until Tiger Lake(Willow Cove).
I think Intel and AMD should take a different approach to improving L2 and L3. L3 is a spillover cache, so it only contains data evicted from L2, but since L2 and L3 contain both data and instruction cache combined, streaming data could essentially be pushing out "more useful" instruction cache. I would prefer if L2 and L3 was split like L1 is, then it could be used more efficiently and more tightly integrated. They could also prioritize lower latency for the instruction cache and more bandwidth for the data cache, etc.
3950x - 4.6-ish GHz Max
What do you mean 4.2 ?
3700x/3800x all core boosts around 4.15~4.2GHz
10980xe all core boost 3.8GHz
3950x all core boost 3.9GHz
As for old gen Ryzen
1800x all core boost 3.7GHz
2700x all core boost around 4GHz
There is unfortunately no realistic third competitor on the horizon.We'll see about those IPC claims.
Stop pretending that hardware bugs is an Intel problem. All desktop CPUs launched in the last ~15 years have a long errata.True, but a few important details;
- Zen boosts cores individually within power and thermal limits.
- Zen also have XFR which is an additional burst speed on top of that.
So actual clock speeds with multicore loads can actually be quite different from rated specs.

here is another vulnerability for intel only as of yesterday, LOL. i swear its weekly now at this point.
