> But Apple cannot beat Intel/AMD in single-thread performance It's literally one of the main Apple M chips advantage over Intel/AMD. At the time when M chip came out, it was the only chip that managed to consume ~100GB/s of MBW with just a single thread. https://web.archive.org/web/20240902200818/https://www.anand... > From a single core perspective, meaning from a single software thread, things are quite impressive for the chip, as it’s able to stress the memory fabric to up to 102GB/s. This is extremely impressive and outperforms any other design in the industry by multiple factors, we had already noted that the M1 chip was able to fully saturate its memory bandwidth with a single core and that the bottleneck had been on the DRAM itself. | ||||||||

Memory bandwidth is an uncore thing, not a core thing. Apple's uncore is amazing. But that means they can feed their cores well, not that their cores are actually the absolute best performers when all the stops are pulled out. | ||||||||
