Tools like powermetrics or mactop consistently underreport GPU power usage on Apple M-series silicon. Worse, many reputable websites and Youtube channels use these tools to report and compare Apple chip power usage with the competition. For

Right now, the AMX units are significantly more efficient in GFLOPS/Watt than the GPU, but I wonder if that changed with the M5's new Neural Accelerator aka tensor cores.

Many reputable websites and channels “measure” the power consumption of Mac computers using apps like Max Power Gadget or asitop. These apps are built on top of the powermetrics MacOS facility. However, in the man pages of the facility it i

Uhm, we can expect close to 8 FP32 TFLOPS from the CPUs alone on the M3 Ultra. It comes with 4 tensor engines (AMX) each capable of about 2 TFLOPs. M3 Max GPU benchmarks around 14 TFLOPs, so the Ultra should score around 28 TFLOPs. Double t

That's probably because SPEC is also a "separate task" based benchmark.

Compared to the M1, they kept the number of memory channels the same but increased the width of each channel. What are the performance implications of this from a pure CPU workload standpoint?

Does the 8GB variant have all 8 channels or just 4?
