A fresh pair of Cinebench R20/R23 scores of Intel’s 12th Gen flagship (we’re assuming that’s what it is) and by all previous accounts, it seems like that’s what it is. Anyway, pardon my enthusiasm and lack of coherence, for I am barely fit to function at the moment. The Cinebench R20 and R23 scores of the Core i9-12900K show a net IPC increase of at least 20% more than AMD’s Zen 3 core (assuming this SKU isn’t overclocked to hell).
Comparing the above scores to the Core i9-11900K and the Ryzen 9 5950X (present Intel and AMD flagships), we’re looking at a single-threaded performance gain of 20% and 25% with Cinebench R23 and R20, respectively. This means that even if the benchmarked ship is overclocked, we’re looking at an IPC gain of over 15% more than Zen 3 and Cypress Cove.
The multi-threaded score paints a similar picture. You can read the entire story here for that here.
