Testing and Performance – CPU

In Cinebench R23 the new Core i9-12900K takes the fight to AMD Ryzen 9 5950X. Despite using a lower number of cores Intel is practically in a dead heat with AMD.

The secret to Intel's Multi Core performance is the punch you get from each core. Intel dominates the top of this chart, demonstrating that 12th Gen delivers on IPC despite taking a small step back on clock speed from 11th Gen Rocket Lake.
