Fields

• shaderEngineCount :: Word32

  shaderEngineCount is an unsigned integer value indicating the number of shader engines found inside the shader core of the physical device.

• shaderArraysPerEngineCount :: Word32

  shaderArraysPerEngineCount is an unsigned integer value indicating the number of shader arrays inside a shader engine. Each shader array has its own scan converter, set of compute units, and a render back end (color and depth buffers). Shader arrays within a shader engine share shader processor input (wave launcher) and shader export (export buffer) units. Currently, a shader engine can have one or two shader arrays.

• computeUnitsPerShaderArray :: Word32

  computeUnitsPerShaderArray is an unsigned integer value indicating the physical number of compute units within a shader array. The active number of compute units in a shader array may be lower. A compute unit houses a set of SIMDs along with a sequencer module and a local data store.

• simdPerComputeUnit :: Word32

  simdPerComputeUnit is an unsigned integer value indicating the number of SIMDs inside a compute unit. Each SIMD processes a single instruction at a time.

• wavefrontsPerSimd :: Word32
   
• wavefrontSize :: Word32

  wavefrontSize is an unsigned integer value indicating the maximum size of a subgroup.

• sgprsPerSimd :: Word32

  sgprsPerSimd is an unsigned integer value indicating the number of physical Scalar General Purpose Registers (SGPRs) per SIMD.

• minSgprAllocation :: Word32

  minSgprAllocation is an unsigned integer value indicating the minimum number of SGPRs allocated for a wave.

• maxSgprAllocation :: Word32

  maxSgprAllocation is an unsigned integer value indicating the maximum number of SGPRs allocated for a wave.

• sgprAllocationGranularity :: Word32

  sgprAllocationGranularity is an unsigned integer value indicating the granularity of SGPR allocation for a wave.

• vgprsPerSimd :: Word32

  vgprsPerSimd is an unsigned integer value indicating the number of physical Vector General Purpose Registers (VGPRs) per SIMD.

• minVgprAllocation :: Word32

  minVgprAllocation is an unsigned integer value indicating the minimum number of VGPRs allocated for a wave.

• maxVgprAllocation :: Word32

  maxVgprAllocation is an unsigned integer value indicating the maximum number of VGPRs allocated for a wave.

• vgprAllocationGranularity :: Word32

  vgprAllocationGranularity is an unsigned integer value indicating the granularity of VGPR allocation for a wave.
