The VF2 has a Imagination Technologies BXE-4-32 (MC1) for it’s GPU as part of the JH7110 SoC.
My ASSumption would be that everything that is possible with that hardware, which should eventually be open sourced by Imagination Technologies will become available. So:
OpenCL 3.0
OpenGL ES 3.2/2.0/1.1 + Extensions
Vulkan 1.2
The key features on Imagination Technologies website for the BXE-4-32 (mc1) are:
API Support
- Vulkan 1.2
- OpenGL ES 3.x/2.0/1.1 + Extensions
- OpenCL 3.0
- Android NN HAL
OS Support
- Linux Consumer
- Linux X.org
Compression
- IMGIC Framebuffer Compression
- PVRTC, ETC and ASTC Support
Performance
Floating point operations per clock
- 32 FP32 FLOPs/Clock
- 64 FP16 FLOPs/Clock
Pixels per Clock
- 4ppc
The features in the JH7110 datasheet, are far more detailed, currently in listed in section “2.3.3. GPU”, but I’m only going to list the first few lines:
The GPU of JH7110 has the following features.
• IMG BXE-4-32 MC1 with work frequency up to 600 MHz (400 MHz by default)
• Fully compliant with the following APIs:
◦ Support OpenCL 3.0
◦ Support OpenGL ES 3.2
◦ Support Vulkan 1.2
