Chinese GPU maker Jingia Micro is developing a new GPU that comes close to rivaling the NVIDIA GTX 1080, at least on paper. The JM9271 offers fast clocks, PCIe 4.0, HBM memory, and a 200W TDP. Jingjia's focus seems to be on the specialized military applications market at the moment, but support for DirectX 12 and Vulkan APIs could make it potentially suitable for gaming.
