Generally unknown to the battalion, at least in our latitudes, the Chinese manufacturer Gitstar announced its JH920 this week. This small graphics card, designed for the Mini-ITX format, develops higher performance than the late GTX 1050… but with support for certain modern technologies, such as AMD’s FidelityFX Super Resolution.
Rarely memorable, Chinese GPUs generally lag abysmally technologically behind those of Nvidia, AMD or even Intel. Proof of this is with the new creation from the manufacturer Gitstar: the JH920, which clearly does not shine with its performance in 2023, but which could do well in terms of supported technologies, consumption and potentially price.
Unveiled this week, this small graphics card is intended for multimedia uses and gaming at 1080p. It adopts a format adapted to compact Mini-ITX cases (173.29 x 126.35 x 41.89 mm) and would, according to Gitstar, develop superior performance to that of the Nvidia GeForce GTX 1050 – with a nice bonus as a bonus: support for AMD’s FidelityFX Super Resolution technology (or FSR), a competitor to Nvidia’s DLSS and Intel’s XeSS.
Not crazy, but a good base?
We also learn that the Gitstar JH920 supports the OpenGL 4.0, Vulkan 1.1, OpenGL ES 3.2, and OpenCL 3.0 APIs. No mention is made of DirectX, however, but Gitstar explains that its card supports HEVC (H.265) Encode and H.264 codecs, and that it is capable of handling a maximum of four screens in 4K at 60 Hz through its four HDMI 2.0 ports. In addition, creative applications such as those from the Adobe suite (Photoshop, Illustrator, etc.) would also be supported.
Still, on a technical level, Gitstar doesn’t show us anything very fancy. Its GPU is clocked at 1.2 GHz and would develop 1.2 TFLOPs (in FP32). This chip could very well be manufactured by the Chinese company Jing Jiawei (which had already supplied chips to Gitstar in the past) but we do not have confirmation of this at this stage. On the JH920, this GPU is in any case supported by 4 GB of GDDR6 video memory, mounted on a 64-bit bus delivering only 96 GB/s of bandwidth.
Obviously, the whole thing would be limited to a thermal envelope of 30W, which is equivalent to the consumption of a small laptop GPU. Understand that it will therefore be possible to power the card only through its PCIe connector, without connecting it to the main power supply. Practical for compact configurations.
Expected later in October, on the Chinese market, the Gitstar JH920 should finally have the merit of being affordable. It remains to be seen whether all the promises of compatibility and support mentioned above will be honored. We know from experience that this is, unfortunately, not always the case with Chinese graphics cards.
