Innosilicon Fantasy II: Low-Power-China-GPU mit bis zu 1,5 TFLOPS bei 15 Watt TDP

Innosilicon Fantasy II: Low Power Chinese GPU with up to 1.5 TFLOPS @ 15 Watts TDP


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

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

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

The technical specifications of the graphics processor are read according to the official data published on the Chinese website They were published as follows:

Innosilicon Fantasy II
  • PCIe 3.0 x8
  • 48 gigapixels per second
  • 2 to 8GB LPDDR5X @ 10Gbps
  • 1.5 TFLOPS for FP32
  • 12.5 CAPS for INT8
  • 1 × display port
  • 2×HDMI2.0
  • 1×VGA

The “Fantasy II GPU” is said to be in a state of the art”5nm process node“Come off the assembly line, according to the manufacturer.

Low power GPU in OpenGL benchmark

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

i like chinese site TIHome reported, the Innosilicon Fantasy II achieved a score of 6,500 points in this benchmark.

Support for Windows and Direct X11

In addition to Linux, Innosilicon Fantasy I and Fantasy II also support Windows and the Direct-X11 API, which the manufacturer was able to demonstrate during the presentation with its own showcases and games like League of Legends.
