[Tom's Hardware] Chinese Vendor Developing PCIe 4.0 GPU With 16GB HBM and GTX 1080-Like Performance

Quote:
Formally constituted in 2006, Jingjia Micro is a Chinese military-civilian integrated company that specializes in electronic component design and production. The firm has started racking up accolades, such as producing the JM5400, China's first domestic GPU. The JM5400 is built on a rather primitive 65nm manufacturing process. However, it later replaced many archaic ATI M9, M54, M72 and M96 GPUs often used in Chinese military aircraft. After the JM5400's success, Jingjia Micro transitioned from the 65nm node to the 28nm node and added the JM7000 and JM7200 GPUs to its arsenal.

As per cnBeta's report, the JM9231 and JM9271 will be Jingjia Micro's upcoming high-performance GPUs. The first performs close to a GeForce GTX 1050 while the latter boasts performance figures in the same ballpark as a GeForce GTX 1080. In terms of TDP, Nvidia evidently has the upper hand. Pascal-powered graphics cards make use of the 16nm process node while Jingjia Micro's offerings still rely on the 28nm manufacturing process.

The JM9231 is expected to arrive with a boost clock above 1,500 MHz, 8GB of GDDR5 memory and a 150W TDP. The JM9231, which most likely is the flagship model, will come with all the bells and whistles, like support for the PCIe 4.0 interface and up to 16GB of HBM (High Bandwidth Memory) memory. It's rated with a 200W TDP and purportedly boasts a boost clock that scales above the 1,800 MHz mark.

I am confused. Are those NV based GPUs, that have been re-worked a bit, like the Dhyana CPUs?

That's a good question, but I would suspect they are more likely to be gcn, ncu or rdna based and the performance equivalence is application specific.

Smaller companies can do some good stuff though. My 2013 VIXS chip in my Panasonic tc58ax800u generally outperforms whatever Samsung tossed in my 2018 QN65Q6FN. In terms of menu usability and options the Samsung is just plain cheap junk. Samsung has a brighter picture with better motion for blacks though. VIXS sold for $20 million in 2017. My tv probably wouldn't have had DP1.2 if not for that company.

And if you somehow got one of these off of aliexpress or somewhere, there would likely be driver issues.
But could be fun to play with as long as it wasn't your primary.

Is this licensed? Unless it's using >=20-year old tech there's a massive forest of patents you need to be able to make a GPU.
If so, why wasn't it blocked by the US under ITAR or similar laws?

It is purely Chinese IP. They are also both planned for 2020+.

If I read it correctly, this is their first Unified Shaders series.

Looks to me as it might be a more efficient Vega 64 on a larger node? Impressive, I wouldn't buy it though.

Nobody can enforce western patent laws on Chinese military. If they sell it in US it's a different story, of course.
Won't go anywhere without gaming drivers, and it's not meant to play games anyway.

On a somewhat serious note it sounds like they have a 980ti. 28nm process, ddr5 ram, in the performance ballpark of a 1080, slightly higher TDP. Definitely sounds like a 980ti with 2 more gb of ram to me.
