    I was looking into this for LLMs but it's clearly a graphics-processing focused card. The memory bandwidth is too low for that much RAM to be useful in an LLM context. The 5090 I have has the same amount of RAM but far more bandwidth and that makes it much more useful.

    Time to first token is a very important performance metric, as I figured out using a Mac Studio M3 Ultra (that is quite slow on this aspect).

    But 32GB for a TDP of 230W is perhaps not super interesting. Especially because you probably want to have more than one card. It's a lot of heat. You could use the cards for heating up a building, but heatpumps exist.

      A lot of the TDP is reserved for running the shader units at full-power. My RTX 3070 Ti only pulls ~110w of it's 320w running CUDA inference on Gemma 26b and E4B.
      • Scaevolus 44 minutes ago
        It's not that it's reserving power, but rather that you hit some bottleneck on a 3070 Ti before running into thermal limits-- it's likely limited by either tensor core saturation or RAM throughput. Running the workload with Nvidia's profiling tools should make the bottleneck obvious.

          Generally the bottleneck is RAM throughput. Inference, in particular token generation, especially on a single user instance, is not all that computationally complex; you're doing some fairly simple calculations for each parameter, the time is dominated by just transferring each parameter from RAM to the cores. A 31B dense model like Gemma 4 has to transfer 31B parameters (at 16 bits per parameter for the full model, though on consumer hardware people generally run 4-8 bit quantizations) from RAM to the cores, that's a lot of memory transfer.

          Prompt processing or parallel token generation can do a bit more work per memory transfer, as you can use the same weights for a few different calculations in parallel. But even still, memory bandwidth is a huge factor.

    For those that use Blender, in their section about Blender:

    > We hope that, in the future, there will be real options other than NVIDIA for GPU-based rendering, as it is an area where competition is nearly non-existent.

    And Checking opendata.blender.org, a NVIDIA GeForce RTX 4080 Laptop GPU scores 5301.8, while Intel Arc Pro B70 is still at 3824.64.

    So there is still a bit more to go before Intel GPUs perform close to NVIDIA's.

    $950 for 23TF fp32? Have GPU performance grew in past 5-10 years at all?

    I would like one for the vram but I am sure they will be unobtainable after the initial stock sells out as I assume they were produced before the RAM prices went up.

    From what I've read the Intel drivers are terrible and holding back using them for LLMs.
    • marshray 16 minutes ago
      I don't know about LLMs, but I tried an Intel card when Ubuntu Wayland couldn't initialize a 2 year old Nvidia. It just works.
    • martinald 48 minutes ago
      Don't think that's true. The drivers are bad (not sure terrible is fair, they have improved a lot) esp for older directx etc games. But Vulkan support is pretty good and that's all you need for LLMs really.

      Everyone has terrible drivers here aside from Nvidia.

      Intel looks like they'll leave the dedicated GPU space, so it's a bit doubtful if the drivers will ever catch up.

    Is Intel still making GPUs? I have heard so many conflicting things about will they/won't they stay in the market.
    • numpad0 22 minutes ago
      Intel always had that habit of starting an internal conflict whenever whatever potential alternative revenue sources start to threaten their internal dependence on x86

      I don't know what to believe when it comes to Intel news because they have so many haters.
    • dismalaf 51 minutes ago
      They'll always have iGPUs so whether or not they stay in the dGPU market depends mostly on whether or not people buy them. So they might not, whole market seems to be moving to SoCs/APUs/whatever you want to call them.

    Here are some llama.cpp benchmarks for it: https://www.phoronix.com/review/intel-arc-pro-b70-linux/3

    It looks like, if one can afford it, the R9700 is worth the extra money.

    I read that Intel is getting out of the dGPU space, but then again, their iGPUs are really getting good. I can't understand why they'd give up the space when the AI market is so insane.

      Rumors of their exit from dGPU predate Battlemage. So I wouldn't put a ton of credence to them. But Intel's is quite talented at snatching defeat from the jaws of victory.

    Can you use those AI cards for gaming too?

    Or the makers intentionally nerf them, in order to better segment the markets/product lines?

    • ZiiS 57 minutes ago
      The drivers often need per game optimisations these will be missing but I doubt Intel would nerf them, just rely on you not paying a lot for RAM the game won't use.
      • XCSme 38 minutes ago
        I actually meant it in a different way. I would get it for local AI stuff, but being able to game on it would be a huge plus, otherwise I would need two different machines.
    • wmf 29 minutes ago
      They nerf gaming cards to make money on the pro cards. Since this is a pro card it's not nerfed.
  • cubefox 15 minutes ago
    Why are they still using their old Xe2/Battlemage architecture rather than their new Xe3/Celestial? They already used it in their Panther Lake chip set.

    These seem amazing for hobbyist, but that TDP given the perf might be an issue deploying a lot of them
    • zrm 1 hour ago
      Its performance is pretty unbalanced. If you're using it for the couple of things that it's good at, the TDP is competitive.
