Given the _actual_ performance metrics that they gave about its Xe HP cousin (which Intel didn't publish any indication on it having FP64 at all), I'm inclined to believe that the 1PF number is indeed some very ML-specific stuff.

When excluding ML... (because that's what Intel gave actual metrics on for Xe-HP)

41Tflops FP32 with 4 dies. For comparison, an RTX 3090 (arch whitepaper at https://www.nvidia.com/content/dam/en-zz/Solutions/geforce/a...) has 35.6Tflops FP32, with a single die.
