Chinese Moore Threads introduced the MTT S70 graphics card with a stripped down GPU and 7GB of video memory

The Chinese company Moore Threads introduced the MTT S70 desktop graphics card. The novelty differs from the previously released older model MTT S80 in a reduced number of graphics cores, less available video memory and the lack of support for the PCIe 5.0 interface.

The MTT S70 is based on a graphics processor with 3584 cores based on the MT Unified System Architecture (MUSA). The chip operates at frequencies up to 1.6 GHz. For comparison: The MTT S80 has 4096 MUSA cores with up to 1.8 GHz. As a result, the MTT S70 only delivers 3.2 teraflops of computing power, which is 22% less than the older model.

The card received 7GB of GDDR6 memory, which is a very unusual amount of RAM for a graphics accelerator. The memory offers a bandwidth of 392 GB/s. This means that the graphics chip supports a 224-bit memory bus, which is also quite unusual.

With the novelty, one of the most important marketing features also disappeared. The MTT S70 features a standard PCIe 4.0 x16 interface instead of the MTT S80’s PCIe 5.0. Incidentally, the latter is still the only desktop gaming graphics card equipped with this interface. It’s true that it’s of no use to an accelerator of this level.

One of the main problems with MTT graphics cards is their poor software support. They only partially support tessellation and multithreading in DirectX 11. DirectX 12 APIs, Vulkan and even OpenGL are not supported at all, which greatly reduces the potential of the MUSA architecture. However, the company is actively developing the software, ensuring compatibility with different games with each driver version.

The MTT graphics card driver is also not without flaws. For example, the company has not yet solved the problem of high standby power consumption and has not disclosed all the possibilities of the architecture. The performance of the older MTT S80 model is currently on par with the 30-watt GeForce GT 1030 from NVIDIA.
