An enthusiast from Germany, nicknamed Loescherzwerg, turned out to be one of the few people outside of China who could get hold of a Chinese GPU-based MTT S80 gaming graphics card from local company Moore Threads. As its own tests have shown, Crysis can be run in DirectX 9 mode despite numerous optimization problems.
Recall that last year Moore Threads presented its own gaming graphics card MTT S80 based on a Chinese GPU. Before the release, the manufacturer sent out a new product to Chinese reviewers, who subsequently published very similar reviews. Common to all was the lack of detailed analysis and a very similar set of games and programs for testing.
One of the interesting features of the MTT S80 graphics card is that it is technically the world’s first graphics accelerator equipped with PCIe 5.0 interface support. However, as the same Chinese reviews showed, the presence of such a high-speed interface turned out to be superfluous for them. The graphics card has very poor software optimization, which is why the potential of the high-speed bus is not revealed.
MTT S80 is definitely not a premium accelerator and it is not a solution that can compete with the latest NVIDIA GeForce, AMD Radeon or at least the same Intel Arc Alchemist graphics cards. However, the novelty is still interesting, at least from the point of view that the GPU developed in China offers the possibility of playing relatively modern games for the first time.
The specifications of the graphics card indicate that the MTT S80 is based on a 7nm Chunxiao graphics processor with a frequency of 1.8 GHz based on the advanced MT Unified System Architecture (MUSA). The GPU has 4096 cores for FP32 operations and 128 tensor cores. The graphics card received 16 GB of GDDR6 memory with a speed of 14 Gb / s per pin, support for a 256-bit bus and a bandwidth of 448 GB / s. For additional power supply, the card uses an 8-pin PCIe connector . To all this we should also add support for the PCIe 5.0 interface, which even the latest generation of Radeon RX 7000 and GeForce RTX 4000 graphics cards do not have.
Officially, MTT S80 only supports DirectX 9 and DirectX 11 graphics APIs. However, Chinese developers continue to work on optimizing its software. As user Löschzwerg points out, the accelerator in its current state doesn’t even support basic software graphics technologies like tessellation. DirectX 11 support for new items is limited to version 11_1.
According to 3DMark benchmarks, the MTT S80 is significantly slower than the Intel Arc A770, which also comes with 16GB of memory. The difference in performance is between 35% and 64% in favor of the Intel solution. It should also be noted that the Chinese graphics card can only work with tests no more recent than the old 3DMark 03 and 3DMark 06, which are unable to reflect the real gaming performance of modern graphics accelerators. And yet, for those wondering if it’s possible to play Crysis on a Chinese graphics card, the answer is yes, you can. Right, so far only in DirectX 9 mode.
The Moore Threads team continues to work to expand the range of supported games and more advanced graphics technologies for its MTT S80 graphics card. However, even with the latest version of the graphics driver 200.2 and almost three months after the release, the accelerator still has “baby wounds” such as high power consumption in idle mode. Back in Chinese reviews, the graphics card was said to draw around 110 watts even when it’s not doing anything. User Löschzwerg confirmed that the latest driver does not fix this issue.
