## Description

This extension provides the ability to determine device-specific performance properties of Arm GPUs.

It exposes properties for the number of texel, pixel, and fused multiply-add operations per clock per shader core. This can be used in combination with the `VK_ARM_shader_core_builtins` extension that provides the ability to query the number of shader cores on the physical device.
