Is there any good estimate of how much of AMD’s power efficiency advantage can be attributed to TSMC’s process vs Intel’s? I know in GPUs AMD doesn’t enjoy the same advantage vs nVidia since they’re both manufactured by TSMC, and with nVidia actually being on a smaller node, iirc.

7800x3d maxes out around 80 watts (has to be gentle to the vcache), the 14900k can go up to 300w (out of box, though Intel is issuing a new bios to limit that), and they trade blows in gaming.

I would say that's a bit more than process efficiency?

Oh, certainly there are significant architectural advantages, especially for the vcache SKUs in gaming. It would just be interesting to see how much TSMC is still (or maybe further) ahead of Intel. Intel was so used to having the process advantage vs AMD that their architecture could afford to be less efficient. But now that they're the ones behind in both process and arch, they're really hurting, especially on mobile now that AMD is making inroads and Snapdragon X is about to get a serious launch in a week. I'm typing this on a ThinkPad 13s with a Snapdragon 8cx CPU running Windows, and it's a pretty usable device that lasts much longer on a smaller battery than my comparable Intel laptop. It seems to particularly use much less power on standby, although it can't seem to wake up from hibernation reliably.

Aurora has 21K Xeons and 64K Intel X(e) GPUs which provide most of the compute power. The GPUs are made by TSMC.
