Intel "Raptor Lake" i9-13900K Sees 14% Performance Boost with Power-Limit Unlocks
The upcoming 13th Gen Core i9-13900K "Raptor Lake" 8P+16E core processor offers a significant multi-threaded performance increase with its power-limits relaxed, according to Cinebench R23 testing unearthed by OneRaichu. In its default settings, with stock power limits, the i9-13900K draws up to 254 W of package power, where it scores 35693 points. With the power limits unlocked in the motherboard's UEFI setup program (i.e. PL1/PL2 set at an impossible 4096 W), the processor's package power peaks at 345 W (a 36% increase in peak power-draw), but results in a multi-threaded score of 40616 points, or a 13.8% performance gain.

so with stock power limits in place it actually consumes less then a 12900k?If so that is pretty damn good.
wait correction, I seem to have my data from whole system power draw instead of just the cpu, my bad.
From what I found real quick it seems the 12900k peaks at 238 watts so the 13900k does actually draw a bit more power.
if I remember the PL for 12900K was set to 241W but here its 254W! i agree!
Really?
And they thought Rocket lake was bad.... :twitch: That's what my MSI Z590 Unify does too if you select water cooler option.

13700k 280W + 8 more e cores = 350W

I'm speechless That's just a binary value - they double every time like with RAM
They never expect that value to be reached, but doing so lets them have finer control (every extra number could be used for a decimal point, etc)
