    Matrix Awakens Demo compiled with new Unreal Engine 5.1

    Posted: 21 May 2022 06:24 AM PDT

    Someone compiled the Matrix Demo with the latest Unreal Engine 5.1 main branch on Github. UE5.1 offers significant improvements such as inclusion of transparent reflections on glass, performance improvements and the integration of DX12 Ultimate.

    It runs significantly better in my test compared to the builds before. It also includes a settings menu and DLSS.

    Note: You need a DX12 Ultimate capable GPU to run it (RTX 2000, RTX 3000 and RX 6000 series)

    AMD Radeon RX 6650 XT, 6750 XT, 6950 XT Meta Review

    Posted: 21 May 2022 02:21 AM PDT

    The benchmark selection for this meta review is significantly smaller, since the highest possible accuracy is important in view of the small differences on these cards. This cannot be achieved by comparing a manufacturer model of the 6950XT with a reference model of the 6900XT. Thus, you only get distorted results about the performance difference of this graphics card.

    Ultimately, there are only two ways to do this correctly: A comparison purely with reference cards (TechPowerUp). Or a comparison on simulated reference cards (ComputerBase, PC Games Hardware, Quasarzone, TechSpot). Igor's Lab have tried a third way: A comparison of consistently factory-overclocked models from the same manufacturer (MSI). This often delivers similarly good results. However, sometimes the problem arises that the factory overclocking factor is different, which leads to a distortion of the performance difference.

    • geometric mean in all cases
    • standard rasterizer performance without ray-tracing and/or DLSS/FSR
    • stock performance on (usual) reference/FE boards, no overclocking

    Radeon RX 6950 XT Reference vs. factory oc'ed Models from Gigabyte, MSI, Sapphire

    Posted: 21 May 2022 06:40 AM PDT

    The various reviews of the Radeon RX 6950 XT made by TechPowerUp now allow a comparison of factory overclocked models versus the reference model by AMD. Only one of the factory overclocked models (MSI) achieved a noticeably better performance, which was, however, connected with a drastically higher power consumption.
