With the Innosilicon Fantasy II, the Chinese semiconductor developer is expanding its portfolio of GPUs with a low-power graphics processor for the desktop, cloud, server and metaverse. While the Fantasy I GPU delivers up to 10 TFLOPS with a TDP of 50 watts, the Fantasy II GPU delivers 1.5 TFLOPS with only 4 to 15 watts.

The community has an eye on the China GPUs

As the Twitter user @Loeschzwerg_3DC, who has also been active in the ComputerBase community as “24784ds” since 2007, shared via the short message service Twitter, the 2nd generation of the “Fantasy” graphics processor has now been officially released by the Chinese semiconductor developer Innosilicon , who has his GPU designs manufactured by TSMC, Samsung, SMIC, UMC, Intel and Globalfoundries, among others.

The GPU intended for the desktop, server, cloud and metaverse, among other things, is based on technology from Imagination Technologies and supplements the Innosilicon Fantasy I a low-power GPU that can be configured with 4 to 15 watts cTDP and provides up to 1.5 TFLOPS for FP32 calculations and 12.5 TOPS for INT8 tasks.

According to the official data published on the Chinese website 168.com, the technical specifications of the GPU read as follows:

Innosilicon Fantasy II

  • PCIe 3.0 x8
  • 48 gigapixels per second
  • 2 to 8 GB LPDDR5X @ 10 Gbps
  • 1.5 TFLOPS for FP32
  • 12.5 TOPS for INT8
  • 1× DisplayPort
  • 2× HDMI 2.0
  • 1× VGA

According to the manufacturer, the “Fantasy II GPU” is to run off the assembly line in a state-of-the-art “5 nm Process Node”.

Low-power GPU in the OpenGL benchmark

The passively coolable low-power graphics processor can be combined with 2, 4 or 8 gigabytes of LPDDR5X, LPDDR5, LPDDR4X and LPDDR4 and has now appeared for the first time in the OpenGL benchmark GLmark2, as @Loeschzwerg_3DC reports again.

As the Chinese website ITHome reports, the Innosilicon Fantasy II achieves a result of 6,500 points in this benchmark.
