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).

Your focus on gaming means nothing to me I didn't build this computer to meet your needs lmao. You have no idea what my budget is only your own, so your opinon is based on your own budget. The final rub here is you don't get to determine what is a good buy or a bad buy for someone else.
You intel fans are ridiculous you are not converting anyone here. If I do another $250 upgrade when Zen 3d comes out you gonna tell me it was a bad choice and I should have gone intel.....
And this is my last response to you don't have time for your mental gymnastics.
Sounds like he has recovered his costs very well. Yes the 5800x is the most pricey of the 4 cpus but prices have come down a lot these days and is only marginally higher than the others. As for X570 motherboards, you can buy some good boards for around $200US.
It's his money, whether you think its a waste or not, is not your concern.
Give it a rest mate!
