Jingjia JM9271 Chinese GPU performs as a GeForce GTX 1080 consuming 20W more

Neither AMD nor Intel, it seems that the true short-term rival of Nvidia, if I wanted to, it's about the Chinese company Changsha Jingjia Microelectronics (Jingjia Micro), a military-civil company created in 2006 that has released its latest graphics cards known as JM9271 and JM9231.

This company, which closed the first half of 2019 with revenues of only 36 million dollars, is growing by leaps and bounds (+ 34.54% of revenue in 1 year), and proof of this is in its latest consumption graphics chips, which are capable to compete with the Nvidia GeForce GTX 1080 and Nvidia GeForce GTX 1050.

The most advanced model is about JM9271, where we only know that it uses the interface PCI-Express 4.0, its silicon reaches 1,800 MHz throwing a Pixel Rate of 128 GPixel / s and FP32 performance of 8 TFLOPs. It is seasoned with 16 GB of HBM memory with a bandwidth of 512 GB / s, and all this gives a TDP of 200W, not bad if we consider that its performance is comparable of a GeForce GTX 1080 with a consumption of 180W.

On the other hand we have the JM9231, which arrives to compete with the GeForce GTX 1050, and for this it uses the interface PCIe 3.0 with a silicon @ 1500 MHz beside 8 GB of GDDR5 memory throwing a bandwidth of 256 GB and reaching a yield of 2 TFLOPs, although it is slightly more powerful than the GeForce GTX 1050, its consumption kills it, since it throws 150W in front of the 75W of Nvidia. Both graphs could be employing a manufacturing process of 28nm.

At the moment, the GPUs JM9271 and JM9231 planned could be exclusively for military use. This is evident since both GPUs apparently lack support for DirectX 12 and Vulkan APIs, being only limited to OpenGL 4.5 and OpenCL 2.0. If Changsha Jingjia Microelectronics wants to steal a piece of the cake from Nvidia and AMD, he will have to incorporate both functions to have a graphics card for players.

On the other hand, the GPUs they are probably in the early stages of development, and there is still time to make changes to the product, as long as the company does not seek to focus only on the military field, of course, but if not, and the price is aggressive, this company could do a lot of damage in the Chinese gaming market, the most profitable of all.
