Intel to Clock "Rocket Lake-S" High, Evidence of an ES with 5.00 GHz Boost

[dicktracy]

I guess it really depends on Zen 3. If they still underperform vs Skylake, then Rocketlake will be the logical choice for those who want next-gen gaming performance.

So IPC improvement with more cache, that also generates heat, so the multicore speed is slower and suffers. Well paint me suprised.....

Not sure where you're getting this 10% number. Willow Cove offers a generational (10-15%) improvement over Sunny Cove, which is well known to have met or exceeded Intel's stated IPC improvement over Coffee Lake (can't remember if 14 or 18%). The only reason Ice Lake didn't show it was because maximum attainable clocks on 10+ were abysmal and negated most of those improvements.

Please don't tell me that "10%" came from Moore's Law is Dead.

That said, Willow Cove is supposed to feature more/updated L3 as its headlining feature. All the leaks around Cypress Cove show that the 8-core ES has exactly the same amount of L3 as existing 8-core SKUs from Coffee 8-core and Comet 10-core dies. Intel did say it was a "reworked cache structure"...

Not sure where you're getting this from, the vast majority of gains on Sunny Cove have come due to AVX512 & while its successor may offer double digit gains I'm struggling to see where they'll pull this from ~ perhaps some exotic instructions that'll become mainstream a decade after Intel introduced them?

It is sad...SIngle thread seems not bad (similar like i9-10900K on Turbo 5.2-5.3 GHz), but multithread is nothing special...
On both sides are some results a little worse or a little better (9900K stock and 3700X database of stocks setting)


stock Ryzen 7 3700X vs Rocket Lake


stock i9-9900K vs Rocket Lake

Wow 5 Ghz, wait haven't we seen that before. Oh yeah the last 2 or 3 gen cpu 14 nm off cause

Yeah if you can't tell, I'm not impressed by Intel lately.

Go read any of AT's articles including the Surface Book Picasso vs Ice Lake comparison / Ice Lake Preview / Ice Lake Review / 3700X and 3900X review. SPEC2017 uses AVX2 on AMD and Intel, not AVX512. AMD vs AMD comparisons on 2017 are also in line with AMD's IPC claims. The only clickbait IPC claims are the hype "leaks" that pegged Ice Lake at 48%+ gains due to AVX512.

The controversy at the time was that Intel was pushing the whole "benchmarks don't matter" narrative; without benchmarks, where do you get IPC tests from? AVX512 wins are blatantly obvious, because the margins are obvious.

Call it for what it is - cheating with AVX512 Ice Lake wasn't. Ice Lake was a promising new uarch stuck on a dung pile of a process that hit a voltage wall long before 4GHz, resulting in a barely competitive, equally warm mobile chip as its predecessors. Sunny and Willow are bigger cores than Skylake, just don't expect 5.3GHz TVB and 10 cores.

Doesn’t look from the numbers like anything much to offer compared to existing lineup. I was hoping for more from a new arch even despite backport.

Some here will think it is the best thing since cheesecake...

I'm not saying you're wrong here, but do you have a source for the IPC gains for Willow Cove?
(Sunny Cove was 18% BTW)

The main feature of Willow Cove is more L2 and L3 cache.
Here look at this table, which one does Rocket Lake most closely resemble?

	Skylake (client)	Ice Lake / Sunny Cove (client)	Tiger Lake /Willow Cove	Rocket Lake
L1 Instruction	32 kB	32 kB	32 kB	32 kB
L1 data	32 kB	48 kB	48 kB	48 kB
L2	256 kB	512 kB	1.25 MB	512 kB
L3	2 MB	2 MB	3 MB	2 MB
