Innosilicon Releases Fantasy 1 Graphics Based on Imagination BXT Architecture

Fantasy 1 will be available as Single GPU Type A and Dual GPU Type B models, but it is not yet known if they will ever be seen in the Western market.

Imagination was once also known in the PC market as a graphics card manufacturer. However, the graphics cards sold under the name PowerVR gave way to computers as early as the turn of the millennium and from then on focused on the mobile market. Now, after a couple of decades, however, the company’s architecture is making a return to the market for more robust circuits as well.

China’s Innosilicon’s Fantasy 1 graphics cards are based on Imagination’s BXT architecture. There are two models coming to market: the Type A with one Fantasy 1 GPU and the Type B with two.

According to VideoCardz’s press conference, the Fantasy 1 graphics chip, and thus the Type A graphics card, offers the user FP32 computing power over 5 TFLOPS. If AI performance is scaled accordingly, 20 INTs with lower INT accuracies would be used. The graphics chip features a 128-bit memory controller that extends as much as 16GB of GDDR6X memory. Innosilicon is said to have made memories run at 19 Gbps, which means 304 GB / s of memory bandwidth.

The Type B of the two graphics chips doubles the theoretical computing power to 10 TFLOPS and the amount of memory to 32 gigabytes, but so far it is only a matter of speculation as to how the dual GPU system will work in practice. Both AMD and NVIDIA have gradually abandoned multi-GPU consumer configurations due to poor practical scalability. On the other hand, both are known to be preparing multi-chip consumer graphics cards in the near future.

Fantasy 1 graphics are PCI Express 4.0 supported and support all modern and less modern interfaces such as DirectX, Vulkan, OpenCL, OpenGL and OpenGL ES on the mobile side. Unfortunately, there is no information about a more detailed level of support for DirectX, for example, but DirectX 12 Ultimate is ruled out, because while Imagination is a pioneer in beam tracking, the feature is not supported by the BXT architecture.

Innosilicon is already working on both the Fantasy 2 and 3 series, and the company is said to plan to use a 5-nanometer manufacturing process with them. Imagination recently released its new CXT architecture, so it is unlikely that at least one of the new features will be based on it.

It is not yet known whether Innosilicon intends to launch its graphics cards in the Western market.
