Intel Core i9-12900K megatest: AMD in 2nd place again

Overall gaming performance

The 12th generation Intel Core processors – Alder Lake is now out and we already have the full-fledged tests for you. These processors are significantly different from the previous ones in many aspects and many things are used “for the first time”. Among them are DDR5 memory support, PCI Express 5.0, 7 nm manufacturing process or hybrid concept of small and large cores. It’s time for a detailed analysis!

Overall gaming performance

To calculate average gaming performance, we normalized the Intel Core i7-11900K processor. The percentage differences of all other processors are based on this, with each of the games contributing an equal weight to the final result. To see exactly what the formula we use to arrive at each value looks like, see “New average CPU score measuring method”.

    1. We decided to treat is as a 7nm process, since it more or less reflects reality, and Intel more or less wants it to be treated like that. The “Intel 7” does not actually say “nm” anywhere, but the follow up processes will actually be marketed like that. The 20A and 18A processes actually refer to Angstroms, which are non-SI units meaning 0.1nm. So those processes are officially 2nm and 1.8nm when it comes to Intel messaging.

      But when we put that aside, in my opinion it is more useful than not to use “7nm” for the Alder Lake chips. Intel’s 10nm process was in fact roughly comparable to TSMC’s N7 (7nm) process, once Intel got rid of the problems (in the SuperFin or Enhanced SuperFin versions). It is not equal parity in everything, but these technologies can be considered competitive. Calling it 10nm makes it look the process is worse than it is if people assume it is similar to 10nm Samsung or TSMC process node.
      We would basically have to keep reminding people that “Intel’s 10nm is on the level of TSMC’s 7nm”. And it’s not practical to to keep repeating that every time. Ideally this should have been done earlier so that the products were not referred to as 10nm for 2-3 years in press.

      In isolation, the process renaming would not be a good thing, but in a way, Intel only did what TSMC and Samsung did before them. Their processes could be said to be renamed already, so Intel just caught up with that marketing. (Not saying they are at the exact same tech level, but it’s in the ballpark for better or worse).
