    So what's the deal with the mgpu stuff? Like wasnt it supposed to use the integrated gpu and the discrete but present to the system as a single gpu with double the shaders and such?

    I will await the actual hardware, I have been ignoring what Raja says for years as it often clashes with reality.

    Ok, going through it all.

    512 Execution Units: https://videocardz.com/newz/intel-confirms-dg2-gpu-xe-hpg-features-up-to-512-execution-units
    Performance of 96 EU: https://www.pcgamer.com/intel-tiger-lake-i7-1185g7-xe-performance-benchmarks/
    Metro Exodus 1080p Ultra no raytracing (no idea there yet): 13 fps average for maximum performance
    Thus performance estimate (roughly): 80 fps 1080p Metro Exodus Ultra no RT

    For reference, 6800 xt is at 130fps for that. RTX 3080 is at... 130 as well. Which gives us an overall idea of Intel's first product, which is to say not high end. More along the lines of a 3060ti, or the upcoming 6700(?) series, with the big unknown being RT performance. With competition for that segment seeming pretty high this year hopefully we'll see heavy price competition.

    You forget one thing: Xe-LP != Xe-HPG
    We don't know whether HPG EU's are the same as LP

    Honestly, I think DG2 is a real life test run for them. Having a product out with good driver is a big thing in itself. It's done with their 10nm ? or 14 ? If drivers are good, and perfs around 3060ti but with a real availability , that's may be interesting...

    Rumours point to DG2 being outsourced to TSMC 6nm.

    I believe they said their EU's are nigh the same across all lines, and it's just other parts/features that are swapped out.

    Looking at the numbers again... if they can get the frequency high enough it might compete with a 3070, but that's a big question mark.

    They've said that at least the vector pipes are configurable in the EUs and I doubt that means in runtime, which suggests not all EUs in different Xes are equal

    Intel Iris Xe UHD 750 IGP inside Rocket Lake-S (11500 ) equals GeForce GT 1030 in perf (guru3d.com)

    Fun fact: the most recent official driver for Xe IGP .9168 does not support Mesh Shader yet.

    Do external developers have access to a Xe driver with Mesh Shader support? Anyone reading this?

    I don't think Xe-LP supports mesh shaders. I think it'll be Xe-HPG that'll support mesh shaders and maybe DX12 Ultimate as well too ...

    Considering they've confirmed RT support, it's hard to imagine Intel not supporting DX12U with Xe-HPG

    Tier 2 VRS and sampler feedbacks might slip through the cracks or maybe they'll support those features too ...

    New specs leaked. There is a model that could be around the AMD 6700XT in performance.

    https://www.pcgamer.com/intel-xe-specs-leak/

    This could be Intel's greatest chance. I'd buy one if they can block mining and those pirate miners. I can't stand them. Now there are GPU "experts" appearing under the rocks. Damn human soul

    Yeah, they don't need to beat the competition, they just need good drivers and be available... But I don't know if Intel will chose to nerf eth mining algorithm...

    I'd love it to be true, but I've burnt too many times to get my hopes up. :(

    Well, Intel would be past PS5 at that point. Im sure they can improve and hopefully bring some competition. Perhaps, they can do ray tracing, somewhat close to NV.
