Japanese tech site computer watch has successfully acquired a Moore Threads MTT S80 graphics card. The card uses a GPU that appears to use the Imagination Technologies PowerVR architecture, despite the obfuscation introduced by Moore Threads management. Even if we turned the clock back to 2015, this wouldn’t be on the list of best graphics cards, but we’d love to see cards like this tested outside of China in the benchmarks and games we’re all familiar with. It’s good to start with

We’re pretty sure the PowerVR architecture is behind the card, but PC Watch reported straight from Moore Threads on the MTT S80 specs. As such, the card uses the Chunxaio architecture and employs 4096 of his MUSA cores. Other specs include a GPU clock speed of 1.8 GHz and a peak performance of 14.2 TFLOPS. The sample tested by PC Watch has 16 GB of GDDR6 14 Gbps memory, connected to the GPU via a 256-bit bus, yielding a bandwidth of 448 GB/s.
The MTT S80 is relatively power hungry with a TGP (Total Graphics Power) of 255W. Perhaps that’s why it includes a triple-fan design. Also interesting is that the card uses a PCI Express Gen5 x16 connector. Of course, these raw specs don’t tell the whole story, and driver support may still be a major factor in performance. But let’s see what PC Watch discovered in our testing.
Before we look at the benchmarks and game tests, it’s worth noting that the PC Watch has found a number of current games that the MTT S80 can’t run, even with a supported motherboard, OS and CPU. . The DX12 and Vulkan games were insurmountable hurdles for this card, but some of his DX11 titles were able to run with varying degrees of success. The latest benchmarks face similar problems and the latest stable and usable version of 3DMark is his 3DMark 06.

|3D Mark 06||28589||61414|
|Unigin Valley (DX9)||2707||5180|
|Counter-Strike: Global Offense (DX9)||92.5||211.5|

Looking at the chart above, we can see that the MTT S80 is doing quite badly against even modest competitors like Nvidia’s GeForce GTX 1050 Ti, a budget GPU that arrived in 2016. In theory, the GTX 1050 Ti delivers 2.1 teraflops of performance. Compute comes with 4 GB of GDDR5 memory, 112 GB/s bandwidth at 75 W TGP. Despite this lack of competitiveness, the Moore Threads graphics card fails.
In the DX9 graphics comparison, the MTT S80 came out the best. It still falls well short of the GTX 1050 Ti, but it’s not completely beaten.Or… well, it’s was Although utterly beaten, the average performance lead in the DX9 test was “only” 86%. So it’s not double the performance.
Things got even worse for the MTT S80 when PC Watch examined a selection of DX11 games. In addition to some rendering errors, the performance was so poor that some games he practically did not run at single-digit fps. Even discounting Asetto Corsa, where the Nvidia GPU was 90x faster, DX11 games still have an average lead of 188%, almost 3x the performance. Even the 1% low on the MTT S80 was terrifying.

|Dragon Quest X||132.7||48.3|
|Rainbox Six Siege||131.5||63.2|
Unfortunately, poor performance and compatibility aren’t the end of the sad story of Moore Threads graphics cards. As it stands, this card consumes a lot of watts for very little power. The MTT S80 averaged 142W power consumption, while the GTX 1050 Ti averaged 60W.
In terms of performance per watt, even discounting the Asetto Corsa (again), the MTT S80 managed just 0.33 fps/W, while the GTX 1050 Ti averaged 1.86 fps/W. This makes older Pascal GPUs more than 5x as efficient.
There is a clear discrepancy between the MTT S80’s raw specifications and actual results. In theory, the MTT S80 has 4x more memory, 4x more memory bandwidth, and almost 7x more than raw his FP32 computing. It’s far from the theoretical performance level.
PC Watch seems to believe that drivers are the main problem with Moore Threads graphics cards, and hopes things will continue to improve in the coming months. For now, the MTT S80 is not for gamers, curious developers, or graphics card collectors.
Back in February, we reported on a video from Korean TechTuber BullsLab Jay featuring the same MTT S80 graphics card. Game testing was limited to his DX9 title due to immature platforms and drivers at the time. The fact that the MTT S80 can now run at least some DX11 games shows progress for the driver, but it still has a long way to go. DirectX 12 and Vulkan games are also not currently supported.
