Compares to Nvidia's GeForce GTX 1650

Zhihui Microelectronics, a China-based developer of graphics processors, has introduced its first GPU which it says has a performance level to that of Nvidia's GeForce GTX 1650 while promising a higher energy efficiency.

Zhihui's IDM929 graphics processor is based on the company's proprietary IDMV architecture and has a pixel fill rate of 19.2 GPixels/s, a texture fill rate of 76.8 GTexel/s and compute performance of 2.5 TFLOPS (presumably FP32).

According to Tom's Hardware, the numbers are similar to Nvidia's GeForce GTX 1650 which was released in mid-2020 which is a sign of how fast the Chinese are catching up with the west.

The graphics processor also supports video decoding in H.264, MPEG2, MPEG4, VC-1, DivX, and VP6 formats. Meanwhile, the unit has four display engines and supports DVI, HDMI, and D-Sub/VGA interfaces.

The GPU is made using a 14nm-class process technology, which could possibly mean that it is made by SMIC and as a clock frequency of up to 1.2 GHz, which is a relatively low frequency for a chip made on a 14nm node

While it is unlikely that the IDM 929 will be good for gaming, it is the first GPU from Zhihui and is enough for office PCs and even for basic home theater PCs. It is also entirely independent of any foreign technology.

Zhihui Microelectronics' main investor Hangzhou Guoxin Technology which develops embedded system-on-chips for applications like TVs, which makes that a logical target for any chips.
