An interesting summary of 13th gen K CPU performance:
Many leaks have come up regarding Raptor Lake's performance in the past few weeks. We made a really comprehensive article showing the performance in
appuals.com
It looks like the 13th gen i9 chips are a bit faster in games, in theory. Maybe there will be a boost in less graphically intensive games, or running at lower resolutions?
I suspect it will come down to power limits and total power consumption.
I wonder if Intel is going to be more overt with their marketing for the 13th gen, soon?
Perhaps they will focus on minimum framerate improvements, which appear quite large in a few titles:
EDIT - these are some weird results at 1080p, you'd expect the minimum FPS to be higher at a lower resolution. Probably an anomaly.
Some of the performance difference may just be related to the increase in clock frequency (although I don't think this would account fully for the difference seen at 1080p and 1440p).
If the performance benefit is mostly related to an increase in L3 cache, the 13900 (non K - Which will have same cache config as the unlocked chip) could be a worthwhile upgrade for some gamers (assuming good DDR5 RAM is used). Maybe the increase in L2 cache might give a boost to the rest of the series too?
EDIT#2 - It doesn't look like the L2 cache increase makes much difference to min. framerate, based on this 12600K /13600K comparison (RDR2):
But, if it's anything like the 12th gen launch, we won't see the locked CPUs and motherboards until a few months after the main launch, so probably January 2023.
