First review of retail Intel Core i9-13900K “Raptor Lake” CPU emerges
TLDR;
13900k compared to 12900k:
~12% higher ST / gaming performance
~ 42% higher MT performance at "unlimited mode"
Power usage have increased from 236w to 343w to reach performance numbers above (so 45% more power usage for 42% higher MT performance)
P-core IPC increase is basically nothing ~1-3%
E-core IPC increase is ~6%
Most of performance increase comes from higher clockspeeds
