Thanks to Mike Bryant for pointing out this Chinese GPU development.

13 year-old Jingjia Micro of Changsha City, China has two GPUs in development.

The JM7200, is a 28nm part clocked at 1.2GHz with 4GB of DDR3 memory. It compares with an Nvidia GeForce GT 640 in performance terms.

The  JM7200 has a 10W TDP, the GT640 has a TDP of 50W.

Jingjia  is said to be developing 28nm JM9231 and JM9271 high performance GPUs which equate to the GeForce GTX 1050 and GeForce GTX 1080.

The  JM9271, has a boost clock of >1.8GHz and uses a PCIe 4.0 bus and is reported to be capable of 8TFLOPs FP32 performance and a pixel rate of >128GPixels/s. It has employs 16GB HBM memory with bandwidth of 512GB/s.

Neither 9271 nor 9231 supports DX12 or Vulkan (just OpenGL 4.5).

The TDP of the JM9271 is said to be 200W.

For parts made on a nine year-old process, the performance levels quoted are high.

It is thought that a move into the commercial market could spark some patent protection activity at AMD and Nvidia.
