What’s so special about having 128 gpu cores when nvidia has had thousands of cores in their gpus for over a decade.
- lern_too_spel 4y agoThis isn't a discrete GPU.
- alberth 4y agoI hear you, but Apple sells today a laptop with 54 gpu/neural-network cores. For a workstation, which this seems to target - doesn’t seem particular a lot to have ~2x that
- dna_polymerase 4y agoCore isn't a standardized unit of measurement. ARM-cores on the Apple Silicon line and the x86-Intel/AMD core behave very differently.
- rbanffy 4y agoFor the CPU cores, M and x86 are converging. M1 had a very expressive lead on gen 11 and 12 Intel because of multiple hiccups on Intel's product pipeline, but that is not going to hold for long. As for the GPU cores, I know very little how they compare, and GPU cores tend to be wildly different between manufacturers.
- intrasight 4y ago>not going to hold for long honest question: why do you think that? My believe is that a good analogy for such leads would be an average marathon runner vs Kipchoge. His "lead" will only increase with time.
- smoldesu 4y ago> why do you think that? Because, love it or lump it, Intel's manufacturing process is ludicrously advanced. Power hungry, particularly when they're locked on older nodes, but extremely capable when their interests align. Pat Gelsinger has even stated that it's his goal to get Apple back as an Intel customer. Their foundry services started working with ARM to get RISC cores manufactured, and if they stick to their roadmap, it's possible for them to leapfrog TSMC's density limitations. We'll have to see where things go, but I do agree with the parent. Apple's lead was their investment on the TSMC 5nm node, which as-of the M2 is clearly difficult to iterate on. Apple needs advancements in density to make a faster chip - Intel does not.
- rbanffy 4y ago> Apple's lead was their investment on the TSMC 5nm node That's only part of the deal. Apple also made some really cool architectural innovations, as well as creating workload-oriented ISA extensions that proved extremely effective.

- lern_too_spel 4y ago38 GPU cores. The neural network inference cores don't do floating point and therefore aren't used for training or games. Assuming these GPU cores are comparable, if >3x isn't a reasonable target, what would you suggest is?
- gpderetta 4y agoNVIDIA hasn't had thousands of cores, unless you count every SIMD ALU lane as a core.
- imtringued 4y agoB-but each SIMD lane needs an instruction pointer for mutexes!
- dragonwriter 4y ago> What’s so special about having 128 gpu cores when nvidia has had thousands of cores in their gpus for over a decade. Its a CPU not a GPU, that’s what is special. (Also, counting shading units, which are often called cores on NVidia GPUs, this has 1024, which still wouldn’t be a lot for a GPU, but 128 vs. the usual way cores are counted for Nvidia GPUs is the wrong comparison.)
- JonChesterfield 4y agoThe CPU has 18 cores according to the link. So probably 9 or 18 x64 things. Wouldn't like to guess how an Intel GPU unit (EU?) compares to a SM or CU from the other two. edit: misc stuff online suggests EU corresponds to a simd. It's sufficiently annoying to find an approximate ratio between that and the main two GPU arch that I'm giving up. Anyone know if 128 is a lot or trivial in this context? My outdated laptop has 8CUs and the better workstation cards are order of 100.
