GeForce GTX 1080 competitor in China

GeForce GTX 1080 competitor in China

Jingjiaewei, a Chinese GPU manufacturer, has announced that the design of its next generation graphics card is now finalized. It could outperform a GTX 1080, a first for China.


This is the third generation of graphics chips from the Chinese company, following the JM5400 in 2017 and the JM7200 in August 2018. The Chinese chipmaker is essentially looking to achieve performance of who was in 2017 by next year using in-house technology. As a result, the JM92 series will include two products, the JM9231 and the JM9271. The first GPU will aim for the performance of the GeForce GTX 1050, while the second will try to outperform the flagship GPU of the Pascal family, the GTX 1080. The first version will feature 8GB of GDDR5 and a base clock exceeding 1.5GHz. The GPU will have a TDP of 150W, which is twice as much as the GTX 1050, whose performance it should match. The 9271 uses 16 GB of HBM 2 memory, giving it a memory bandwidth of 512 GB/s. It has an operating clock of 1.8 GHz and a TDP of 200 W, just 20 W above the GTX 1080 thanks to the use of HBM 2.


On paper, there is nothing to prevent these future cards from integrating a classic PC. Both GPUs will use OpenCL 4.5 and OpenCL 2.0 and will have support for HDMI 2.0 and Display Port 1.3. The larger model that is to supplant the 1080 will use PCIe Gen 4 while the former will be limited to PCIe 3.0 x16. Now there is the problem of mass production. In theory, Jingjiawei would like to have access to TSMC’s 7nm for its future GPUs. Nothing says that the USA will not block this request. The company would then have to turn to a local foundry like SMIC, which does not yet seem to be able to master this process. Under these conditions, the performance ambitions could not hold…
