That chart shows that M4 achieves 25% of the Geekbench scores of GPUs that pull >10x more power. That's definitely efficient.

[bigyabai]

Are you comparing it with other 3nm GPUs? When you normalize for process, Apple Silicon is definitely not the most efficient raster architecture.

[rafram]

It doesn't seem like Nvidia even has any 3nm GPUs on the market. But sure. When you control for power efficiency, it turns out there's no difference at all!

[bigyabai]

Process is not equivalent to power efficiency. It's a step-change enabling better designs.

Apple and Nvidia both have 5nm and 4nm GPUs. Take those scores and divide it by the TDP, you'll be shocked at the difference design can make.

[wtallis]

Please never divide anything by TDP. Use actual power measurements, unless you're trying to ensure your numbers end up being bullshit. (In particular, any number someone claims is a TDP for an Apple processor is made up, because Apple doesn't publish or specify any quantity remotely similar to TDP.)

[bigyabai]

Okay, then don't divide by TDP. Measure the GPU wattage frame-by-frame and you'll still end up with similar numbers. The point stands.

> because Apple doesn't publish or specify any quantity remotely similar to TDP

1) That doesn't mean that power usage isn't measurable.

2) They actually do, although it's not a perfect breakdown chip-by-chip: https://support.apple.com/en-us/102027

[wtallis]

Are you seriously trying to claim that Apple's total system wall power numbers are appropriate for comparing against an AMD or Intel processor TDP number? You really are trying to ensure the numbers you calculate are bullshit.
