The Intel Core i9-12900K scored an impressive 1893 points in single-core and 17,299 points in the multi-core test. This puts the Alder Lake flagship 2% ahead in single-core and 22% ahead in multi-core performance against the Rocket Lake 11900K flagship. This places the Alder Lake chip as the fastest single-threaded desktop CPU ever made but this is just an early glimpse of what it has to offer considering we are still months away from launch.

At the same time, the chip just crushes the AMD Ryzen 9 5950X with an 11% single-core and 4% multi-core performance lead. As stated before, this is still early performance, and the fact that the benchmark isn't even running in Windows 11 OS, which is required for proper operation of the efficiency cores, means that we could expect even higher performance in final retail chips. It also comes down to pricing as AMD won't sit silently while Intel launches its Alder Lake lineup. The red team is expected to drop major price cuts and it makes sense too, considering they will be getting ready to release their own 3D V-Cache Ryzen chips a few months after Alder Lake CPUs ship in the desktop segment.
