Raspberry Pi 4 achieves Vulkan 1.1 conformance, will get as much as 60% GPU efficiency increase

Khronos has simply granted Vulkan 1.1 conformance to Raspberry Pi 4 SBC, and following the implementation of varied optimizations and new options similar to geometry shaders, the v3dv Mesa driver delivers as much as 60% increased GPU efficiency in Unreal Engine 4.

Iglia began Vulkan driver work for Raspberry Pi 4 nearly two years in the past, with the triangle demo showcased in February 2020, adopted by Vulkan 1.0 conformance in November 2020, and now the driving force is licensed conformant to Vulkan 1.1. Whereas many GPUs are conformant, the Raspberry Pi 4 is just joined by a few full platforms together with a number of NVIDIA Jetson modules (Vulkan 1.2),  and presumably some Intel and Google platforms proven as “Confidential” right now.

Vulkan 1.1 Raspberry Pi 4Alex Bate, Digital Content material Supervisor for the Raspberry Pi Basis, explains the driving force modifications for Vulkan 1.1 conformance have already been merged in the upstream v3dv Mesa driver, and may quickly turn into accessible in Raspberry Pi OS. Observe that Vulkan 1.1 conformance was achieved with Raspberry Pi OS Aarch64, i.e. 64-bit Arm, so it’s unclear whether or not the 32-bit model of the OS might be even be supported.

Optimizations and new options to the driving force, plus enhancements to the shader compiler additionally assist produce higher, quicker code, at the very least in particular eventualities with important efficiency enhancements for Vulkan and OpenGL video games and purposes making heavy use of geometric shading.

Raspberry Pi 4 GPU Vulkan performanceThe efficiency enhancements range so much relying on the sport and settings with vkQuake getting a 5% increase, Quake3e shut to twenty%, and Unreal Engine 4 round 25% with low high quality settings and as much as a little bit over 60% for high-quality settings which produce fairly good outcomes.

Sadly that doesn't imply video games developed with Unreal Engine 4 might be playable on Raspberry Pi 4 as efficiency will not be ok for gameplay. Builders can also be happy to know that help for RenderDoc graphics debugger and GFXReconstruct graphics API seize and replay instruments has been improved.
