lmao he’s citing cinebench R15? Which isn’t just ancient but actually emulated on arm, of course. Really digging through the vaults for that one. Geekbench 6 is perfectly fine for that stuff. But that still shows apple tieing in MT and beating the pants off x86 in 1T efficiency. x86 1T boosts being silly is where the real problem comes from. But if they don’t throw 30-35w at a single thread they lose horribly. |

It's the only one where they measured the power use. I don't get to decide which tests they run. But if their method of measuring power use is going to be meaningless then the associated benchmark result might as well be too, right?

It shows Apple behind by 8% in ST and 12% in MT with no power measurement for that test at all, but an Apple CPU with a higher TDP. Meanwhile the claim was that AMD hadn't even caught up on the same process, which isn't true.

They don't use 30-35W for a single thread on mobile CPUs. The average for the HX 370 from a set of mostly-threaded benchmarks was 20W when you actually measure the power consumption of the CPU:

On single-threaded tests like PyBench the average was 10W:

34W was the max across all tests, presumably the configured TDP for that system, derived from the tests like compiling LLVM that max out arbitrarily many cores.
