I was just going by their quoted TDP values, and the HX identifier. Seems like it’d be fair to compare top HX SKUs from 7000 vs 9000.

Otherwise what would be the correct comparison? I don’t see anything else in their lineup that would be a better match.

Igor is correct. The correct comparison for Strix is Phoenix or Hawk Point.

Remember:
  • The thermal conductivity was improved. (Of the chip? Of the interface from chip to heatspreader? Of the heatspreader? AMD didn't elaborate.)¹
  • The placement of on-chip temperature sensors has been changed.²
  • The thermal management algorithms have been changed.²
AMD did this based on lessons about hotspots learned from previous chip generations.²

I already know all of this i was not asking for an explenation. Im still in shock under 60c not delided with my jaw on the floor while driving 130km/h and typing with 1hand

For comparison sake 13900K can do 30500 at 100W PL2.

For clarification sake: a comparison with a more than likely unstable CPU due to an extreme undervolting or extreme low AC / DC loadline values (I know it because I own a 13900k), is totally useless.

Strix Point compared to Phoenix (8945H) also because they are the top monolithic die of their respective generations, and because they both include a large integrated GPU.
Dragon Range (7945HX) to Fire Range (9945HX if they will keep the same naming) being both desktop derivatives which rely on an external dGPU.

27c delta vs 20c chiller setup ???

Yeah, also the leaked numbers from the AMD event were 42k stock and 44k PBO. No way this ES does 46k. Something is off.

I know AMD says it is better, but 7950X ran at 95° pretty much everywhere. There's no way we are sitting at 60° now with 9950X. Also the numbers are higher than the leaked PBO ones.

All the numbers are quite consistent w.r.t. PPC. The stock AMD run had a score of 42k at 5.0 GHz, the ES is 46k at 5.28 GHz, and the mild OC AMD (on LN2) is 51k at 5.85 GHz all core.

Not Tweets, an article.

AMD's Ryzen 9000 "Zen 5" CPUs by default will run cooler than Ryzen 7000 "Zen 4" CPUs. Based on testing with a Ryzen 9 9950X CPU (Default ES), the chip consumed up to 190W of power whereas the Ryzen 9 7950X consumes around 220-ish Watts of power in the same workloads. The workload being performed here is Cinebench R23 and we got some interesting numbers here too. The 9950X is almost as fast as the Core i9-14900KS by default and that chip can consume over 300W of power with its extreme profile.

The slightly under 42K points at stock matches this performance level.

Interestingly it does look like Zen 5 needs more current than Zen 4 at the same power levels. Even at 230W you almost can't get Zen 4 to hit the stock 160A TDC limit, but here you can see it's being exceeded.

But it doesn't make sense that stock ES is better than PBO scores that AMD shows officially. Also

AMDs slide says Ryzen 9000 is 7° cooler at same power. And now this ES runs at 230W with 60°?!?. 7950X needed a chiller to even get to 230W at 95°. Most reviews with AIO measured a Max powerdraw of 190-200W for 7950X because it simply ran into the 95° Limit. So this ES looks to be more like 40-45° cooler at same power. Very suspicious.
