Stock voltage is very high, Raptor Lake's P-cores doesn't need 1.2v to hit 5 GHz, and can do 4 GHz at 0.95v or less. It'll be interesting to see what undervolting does, SkatterBencher's 24-core 2495X uses 1.15v at 4.4 GHz:
Asus does use the V/F curves to generate a rating for the CPU but it's only available with their MBs. I don't think they've publicly released their methodology publicly or licensed it to other board manufacturers, though Gigabyte has recently released their own version...
Are you using a negative offset voltage to undervolt? I find that these kind of reboots are related to idle or low CPU usage voltage being too low.
In my new 13900K system, I had one idle reboot when I was using the a global negative voltage offset. I switched to using the V/F curve to only...
Igor's Lab has an article with an analysis of several hundred 13900K/KFs using the SP values read out with an Asus motherboard. Though after reading the article, it doesn't seem like their is a strong finding for one model over the other...
Raptor Lake uses less power than Alder Lake in games for better performance. The 13700K vs the 12900KS performance/watt improvement is so high you might think it was actually using a new 7 nm process instead of 10 nm.
A Chinese reviewer used a Thermalright AS 120, and undervolted their 13900K to 5.2/4.3 at 1.23V. Power use went down to 190W in Cinebench R23 but still almost hit 40K. Temperatures were only mid 70s to low 80s running the AIDA Stress FPU test.
AMD and Apple have more than 8 P-processors using a MCM approach, which Intel has so far not wanted or unable to do so for the consumer market. To use the old AMD term, neither has a CCX with more than 8 P-processors.
The used benchmark, Cinebench R23 scales almost perfectly with clock speeds. The low difference between 300W and 200W is probably from the 300W runs hitting the overheat limit and frequently throttling the P-cores while at 200W, the P-cores can run continuously at 4.8-4.9 GHz.
The 9700K didn't have HT because it was the #2 CPU in Intel's lineup and it having 8 non-HT cores was enough to trade blows with the 2700x. It didn't need to beat the 2700x in everything, that was the job for the 9900K and its higher price tag.
A nearly 29K score in R23 for the 5950X requires an overclock to 4.5 GHz all core. I'd be surprised if AMD is claiming the 40+% over that, more likely it's against a stock 5950X that scores in the 25.5K range.
Hyperthreaded Sandy Bridge and Ivy Bridge still do better in games today (and even compete pretty well against Zen 1). Their superior per-core performance meant that even two Piledriver "cores" could only match a HTed Bridge core with two threads.
In my experience with patents, the only thing that matters are the claims, which in this case seems to be only related to cache coherency and provides almost no details on the rest of the processor's architecture. Every thing else in a patent is really just fluff.
I guess one way for Intel to...
