Gotta love 125W boost LMAO. Intel, just quit. You suck. Kthxbye
CB R20 score is very linear to CPU clock speed and quite indifferent to other things.
Each GHz results in 105p for Skylake/CometLake, 123pt for Rocket Lake, 129p for Zen3 (maybe slightly less for Cezanne but the difference is very minor), 150p for Alder Lake P-cores (and 105p for E-cores).
Zen3 SMT efficiency is 1.27x, Intel's HT is a couple percent lower at around 1.25x.
CB R20 ST at 689 points is that core running at 4.5 or 4.6GHz, Alder lake at that clock should be ~20W on one core.
For comparison, Zen3 core at same clock consumes 15-17W. Although to be fair, this is really a different comparison because Zen3 core needs ~5.3GHz for the same 689 points result (and goes over 20W already at 5GHz).
Multicore is difficult to analyze because 12700H is apparently a 6P+8E configuration which we have not really seen thoroughly tested. 12900K is 8P+8E, 12700K is 8P+4E and 12600k is 6P+4E.
Rough numbers though:
- If 12700H is running the base 2.8GHz on E-cores which would leave 4.2GHz for P-cores to get that score. 4.2GHz P-core uses 15-16W, so 90-96W plus whatever E-cores consume. So you may be right about 125W
- Alternatively if 12700H is running boost 3,7GHz on E-cores this would need only 3.6GHz from P-cores to get the score. 3.6GHz P-core uses 10W, so 60W plus around 30W for 8 E-cores at these clocks. around 90W.
Keep in mind though that power consumption comes down a lot faster than performance when clocks are decreased.
I like to know where there getting those results from for the 11950H as not even the 11980HK can beat the 5900HX.......so as always these results are total BS.....again
Looking closer at the results - this seems to be a 5900HX with stock power limit applied. Looking at a couple other reviews this means 45W TDP and power limit in 50-60W range.
