| It is hilarious that the SPEC2026 graph does not include apple's P-cores. And no, not because they are ARM and not x86, since Graviton is included. It is because their integer & FP scores of 9.8 & 13 respectively absolutely wipe out everything else on this chart. |

| The single-threaded results of the Apple cores are excellent, but the multi-threaded results per socket of a Zen 6 absolutely wipe out any Apple CPU. The Apple CPUs may be great for a personal computer, but they are not competitive with a server CPU. Moreover, the SPEC floating-point results are not really representative for the floating-point performance of Zen 5 and Zen 6 that can be reached with optimized AVX-512 programs, which is much greater. |

| if you're interested in a fair comparison here's one https://openbenchmarking.org/test/pts/stockfish |

| ▲ | dmitrygr 4 hours ago | parent [-] | | Interesting, but seems to lack single-core benchmarks. | | |
| ▲ | wredcoll 4 hours ago | parent | next [-] | | So this benchmark lists the following: > AMD Ryzen 9 9950X 16-Core 63rd 4 40132379 +/- 2530724 > Apple M5 Pro 52nd 5 22108587 +/- 260160 I have absolutely no idea what this is benchmarking or how, but is there any reason not to just read this as the "consumer/low core ryzen" is twice as fast as the m5 pro? | | |
| ▲ | Tuna-Fish 3 hours ago | parent | next [-] | | Stockfish parallelizes well and makes heavy use of vector operations, and the Zen5 core has AVX-512 with 4x 512bit° EU per core and 16 cores, while the Apple still only uses 128-bit wide SIMD, with the 6 M5 "Super" cores having 4x128 EUs and the 12 "Performance" cores only having 2x128 EUs. The M5 Pro is doing shockingly well given the massive disparity in execution resources. But still, it's optimized for web/desktop-like loads, you shouldn't really run heavy number crunching on that CPU. 0: 2x FMA/MUL + 2X ADD | | | |

| 1. Different market 2. What flags & compiler? 3. Can't run Linux on that M5/M6 can we? |

| ▲ | dmitrygr 4 hours ago | parent | prev [-] | | 1. so is Ryzen 9 9950X | | |
| ▲ | crote 4 hours ago | parent | next [-] | | Regular Ryzen parts are still reasonably relevant for server use! They support ECC, so there's nothing immediately disqualifying them - see the rebranded "EPYC" 4005 series, for example. A company like Hetzner isn't going to care an awful lot whether they deploy one big SP5 server or four small AM5 ones for the VM instances they rent out: the only thing that matters is TCO per performance. Want to stick four NVMe SSDs, a 25Gbit NIC, 256GB of ECC RAM, and some OOB module on a Ryzen board? No problem whatsoever. Want to do the same with an Apple CPU? Ehhh, that's going to be slightly more challenging... | |
| ▲ | trynumber9 4 hours ago | parent | prev [-] | | 1. 9950X isn't on the chart. The 9950X3D2 was already tested. And was included as comparison point with the fastest possible version of its predecessor (Zen 5). Some evidence that contextless numbers are meaningless is that your source, David Huang, does include the 9950X but in his results it scores much higher than everything on C&C's chart too (7.25/11.4) |

| I mean, this is a review of the server grade parts. Apple is not exactly selling m chips to hyperscalers right? Different story when you're talking about the context of a desktop or mobile. |

| ▲ | toast0 2 hours ago | parent [-] | | Ryzen 9950X is basically the same as an Epyc 4565P, except you can buy the Ryzen in a retail box. |
