Allegedly Raptor Lake's top SKU will have the same ~250W PL2 value. It'll have two 8c Gracemont clusters at an unknown clockspeed with extra L2, and if on a newer motherboard (e.g. not z690) it'll have a separate voltage rail available for Gracemont so it won't have to pull the same volts as the Raptor Cove cores. That should improve perf/watt in MT workloads assuming Intel's boost maps for those workloads allows the Gracemont clusters to run at lower clocks and volts than Alder Lake. The 12900k has its 8c Gracemont cluster running at the same voltage as the Golden Cove cluster, and forces clocks to 3.9 GHz which is well out of the efficiency range for Gracemont.Is RPL PL2 going to be the same as ADL?
If so how much do you think performance/watt will increase in MT?
To put a finer point on it, if in full MT scenarios a 13900k can run its 16c Gracemont @ 3.2 GHz with some lower voltage than what is used on Alder Lake's 3.9 GHz 8c Gracemont cluster, you'll see increased throughput without that much extra power draw.
