Intel's own Open Image Denoise library that is part of the oneAPI toolkit was performing very poorly with Alder Lake... Again, an apparent E core issue. On Wednesday afternoon, Intel did release a new Open Image Denoise point release that is reported to address hybrid architecture performance issues.

Highly threaded test cases like the Stockfish and asmFish chess benchmarks were still preferring the Ryzen 9 5950X processor due to its higher thread count.

When it came to code compilation speed, the Core i9 12900K was building software at a similar pace to the Ryzen 9 5950X.

The Core i9 12900K could build a defconfig Linux kernel image in under 50 seconds while the Core i5 12600K took around 69 seconds.

Alder Lake marks the return for Intel to competitive compiler speed performance among desktop CPUs.

But the great build speed performance did come at the cost of much higher power consumption compared to AMD Zen 3.
