>and AMD's cores have significantly higher IPC.
This is most certainly wrong. Apple Silicon has way higher IPC. AMD chips clock much higher, which uses much more energy. Hence, Apple Silicon is much more efficient.
>My 8 core Ryzen 5800x3D certainly compiles code a LOT faster than my 8 core M1 Mac despite the difference in main memory bandwidth.
Code compilation is not bound by memory bandwidth. But AI training and inference is. Hence, we're talking about it.
>Geekbench is a synthetic benchmark. I'd prefer real workloads like compiling code or tokens / s inference.
You send me a link to a synthetic benchmark. All I did was link you to a better and more accurate one.
Also, Geekbench performs real world workloads. You can easily look at individual scores for each test - besides the main score.
- timschmidt 3y agoI looked around for AI specific benchmarks. Seems Openbenchmarking.org has quite a few. The 7940 is just making it's way onto the market, so I chose the closest desktop equivalent with a similar number of cores and memory bandwidth figures. Notably, the 7700 _does not_ have the AI acceleration cores of the 7940, meaning the 7940 will post much higher performance in that area. https://openbenchmarking.org/vs/Processor/Apple+M2,AMD+Ryzen+7+7700+8-Core https://openbenchmarking.org/vs/Processor/Apple+M2,AMD+Ryzen... Sure seems like the M2 is very far behind the 7700 in performance in all areas. Farther than can be explained by the difference in Mhz or package power.
