I'm not sure the clock speeds are correct for this architecture yet. Could you run sudo powermetrics gpu_power --sample_rate 500 and report the results in a text file?

Also Apple 8 is wrong according to metal tables. Possibly because Xcode 15.10b2 is missing .apple8 in the enum?

Here's a more focused command: sudo powermetrics --samplers gpu_power --sample-rate 500 --output-file /tmp/gpu_power.txt

Have you double-checked whether it's in low-power mode? These clock speeds are news to me:

CPU: 3.6 GHz -> 4.05 GHz GPU: 1.398 GHz -> 1.380 GHz

Also, following the Apple developer video, I need to correct this generation's TFLOPS and IPS to "unknown".

@schwa would you mind running the test with the latest version of applegpuinfo?

Thanks. I'll get around to upstreaming these results when I have the time for it.
