NVIDIA’s GeForce GTX 1080 is old news for most enthusiasts, but not for China. A Chinese company called Jingjia Micro (Jingjiawei) has reportedly hit a milestone by creating a graphics card that’s capable of keeping up with the likes of green team’s Pascal flagship and other cards such as AMD’s Radeon RX Vega 64.
Supposedly releasing soon, Jingjia Micro’s JM9271 is a graphics card featuring 8 TFLOPs of FP32 performance, a boost clock rate of over 1,800 MHz, 16 GB of HBM memory, and a memory bandwidth of 512 GB/s. Its output options include HDMI 2.0 and DisplayPort 1.3, while TDP is listed as 200 watts.
Jingjia Micro’s JM9271 is being accompanied by a weaker graphics card labeled the JM9231. Comparable to the GeForce GTX 1050, the JM9231 features 2 TFLOPs of FP32 performance, a boost clock rate of over 1,500 MHz, 8 GB of GDDR5 memory, and a memory bandwidth of 256 GB/s. It shares the same output options as the JM9271 but features a lower TDP of 150 watts.

[…] Jingjia Micro explains that it’s still in early development stages for the two graphics cards, which still have to go through more testing before the company can begin trial production runs. Efficiency is not a strong point of these, though performance is somewhat promising if they’re comparable — at least on paper — to GPUs from several years ago that are still fairly capable in the case of the GTX 1080. There’s also no word on DirectX or Vulkan API support, so it’s possible the JM9231 and JM9271 cards may never end up in a gaming PC.
