Intel Core i9-12900K Allegedly Beats AMD Ryzen 9 5950X at Cinebench R20
With qualification samples of the upcoming Intel Core i9-12900K "Alder Lake-S" processors and companion Socket LGA1700 motherboards hitting the black-market, expect a deluge of benchmarks on social media. One such that stands out makes a fascinating claim that the i9-12900K beats AMD's current flagship Ryzen 9 5950X processor at Cinebench R20, which has been AMD's favorite multi-threaded benchmark. At stock speeds, with liquid cooling, the i9-12900K allegedly scores 810 points in the single-threaded test, and 11600 points in multi-threaded.
To put these numbers into perspective, a retail Ryzen 9 5950X scores 641 points in the single-threaded test, and 10234 points in multi-threaded, in our own testing. The i9-12900K is technically a 16-core processor, just like the 5950X, but half its cores are low-power "Gracemont." The "Alder Lake-S" chip appears to be making up ground on the single-threaded performance of the "Golden Cove" P-core, that's a whopping 25% higher than the "Zen 3" core on the 5950X. This is aided not just by higher IPC, but also the max boost frequency of 5.30 GHz for 1~2 cores, and 5.00 GHz "all-core" boost (for the P-cores).Given the multi-threaded scores, it's safe to assume that either Intel or Microsoft has figured out a way to leverage the P-cores and E-cores simultaneously in peak multi-threaded workloads. This is possible when both the "Golden Cove" and "Gracemont" cores have the ISA capability needed by the workload, which in case of Cinebench R20, is AVX. "Gracemont" is Intel's first low-power core to support AVX, AVX2, and AVX-VNNI instruction sets. "Golden Cove" features a more lavish ISA that includes AVX-512 (select client-relevant instructions).

I can get much more out of my 5950 when removing power limits. And I can as I run custom loop.
Do I need it? Naah.
much better when intel was rocking 4c/8t :(
it's not like the Gen 12 is meant to face Zen 3, i said that back about the "Intel beat [insert previous gen] with his upcoming [insert Intel cpu name]" and then AMD next gen which was made to be the actual counterpart of it did beat or equal it ...
although it's, also, not like a Zen 2 can't hold a candle to a Gen 11 Pond errr... Lake? right?
well good to see Intel not sitting on their thumb ... for once, but well, 2 question in 1 "at what power consumption and at what price." if it eat and cost more than a 5950X : then the 5950X is the winner given the result.
If Intel prices it right then the 12600K will compete against the 5600X and the 12700K against the 5800X and hell, those extra little cores would be really attractive for buyers, as say 6 Big cores from 5600X vs 6 Big Cores AND 4 little cores from 12600K.
My dream is that Intel keeps prices at around Rocket Lake SKUs. That would be so good for the mid range market. But Intel likely will want to raise prices.
not even a R20 screenshot
Just rumor
Anyway, I wonder how it will be priced, are they going to sell them for over 1000 because it's faster than the r9, or are they going to keep the same i9 price and undercut AMD ?
New socket brings new platform concerns this time around as well. Intel's LGA1700 will not be directly compatible with current coolers. DDR5 should also be coming. Same applies to AM5.
Honestly these leaks.....I get it, its clicks etc but man is it a bunch of nonsense.
Speculation in general, what a pointless exercise.
