M2 GPU clock speed #47

Closed philipturner closed 1 year ago

philipturner commented 1 year ago

I've been searching for the M2 GPU clock speed for quite a while. Sources cited by Wikipedia (specifically cpu-monkey) are extremely unreliable, and I'm trying to determine something important about the Apple8 microarchitecture. Compared to Apple7, Apple8 supposedly has double the ALUs. That would mean Apple nearly halved the clock speed.

I have an A15 iPhone, but iOS can't run powermetrics for reverse-engineering. If any users could run asitop - or even just sudo powermetrics, that would help a lot. Just show the text of GPU clock speed range for M2. Thanks!

Nevermind - this YouTube video shows it at 1398 MHz. Apple did not halve clock speed, and their developer video about A15 was probably misleading.
