> Based on multiple benchmarks, the Ryzen 6000 series and Alder Lake series should outperform the M2 Ultra pretty drastically (200-300%, which is well above the M3 general uplift of 20%) unless there's a severe disk bottleneck, which is going to be more of a SSD/PCIe issue than a CPU one (and something that can be configured/improved on PCs). Compilation is strongly memory bound, especially large builds. Rust and Haskell compilers regularly clock a upward of 70 Gb/sec of the memory throughput on the parallel builds of some small to most medium size code bases. Large C++ builds should be the same. Synthetic benchmarks are a poor reflection of such workloads. Having said that, it does not matter how fast is the CPU if it stalls on the memory access, if e.g. the memory bus is not wide enough. Max's 512-bit wide memory bus at 400Gb/sec and Ultra's 1024-bit memory bus at 800Gb/sec can feed the L2 cache much faster resulting in a more even CPU core utilisation and the workload spread.
