# Spec Sheets ## Introduction Information that applies to specific Adreno models is collected here: ## [Renderer Architecture](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-renderer-architecture) On A5x GPUs, the Triangle setup rate is 1 prim/clock (but user clip planes turn this rate into a 50 cycles entire-pipeline stall if a primitive is clipped). ## [Tile-based Rendering](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-tile-based-rendering-best-practices-details) ### [Tile Shading Vulkan Extensions](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-tile-shading-vulkan-extensions) #### [VK\_QCOM\_tile\_memory\_heap](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-vk-qcom-tile-memory-heap-best-practices) A8x: On a deferred rendering implementation, we were able to achieve an over 29% bandwidth reduction using [VK\_QCOM\_tile\_memory\_heap](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-vk-qcom-tile-memory-heap-best-practices). ## [Render Surface Target](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-render-surface-target-device) A6x-A8x supports rendering up to 8 render targets simultaneously ## [Vertex and Index Buffers](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-vertex-and-index-buffers-best-practices) On A7x, the vertex cache size is 32 4D vertices. ## [Texture Features](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-texture-features-best-practices) On A5x GPUs, ASTC is compressed in L2 and decompressed in L1. ETC formats stay compressed in L1. A5x GPUs support up to 32 total textures in a single render pass – up to 16 textures in the fragment shader and up to 16 textures in the vertex shader. ### [Texture formats](https://docs.qualcomm.com/doc/80-78185-2/topic/overview.html#use-astc-texture-compression) The following table describes functionality available for each supported texture format.

[Shaders](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-shaders-best-practices) On A7x GPUs, every time a shader on the graphics queue uses more than a multiple of 2000 shader instructions, there is a potential performance impact. [Compute shaders on LPAC have a different limit.](https://docs.qualcomm.com/doc/80-78185-2/topic/spec_sheets.html#lpac-shader-instruction-count-device-specific) On A7x GPUs, every time a shader uses more than a multiple of 32 vertex buffers, there is a potential performance impact. On A7x GPUs, every time a shader uses more than a multiple of 16 unique uniform buffers, there is a potential performance impact. On A7x GPUs, each time a shader uses more than a multiple of 16 unique textures and SSBOs (summed), there is a potential performance impact. Each time a set of shaders in a pipeline use more than a multiple of N unique samplers (fragment and compute shaders in a single pipeline share this cache; a pipeline’s vertex shaders have an independent cache), there is a potential performance impact: - On A5x, N=4 - On A6x-A8x, N=16 On A5x GPUs, one (1) texture per fragment at full rate is equivalent to 16 full precision ALUs. ## [Compute Shaders](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-compute-shaders) On A7x GPUs, every time a compute shader on LPAC uses more than a multiple of 2256 shader instructions, there is a potential performance impact. [Compute shaders on the Graphics queue have a different limit.](https://docs.qualcomm.com/doc/80-78185-2/topic/spec_sheets.html#instruction-count-device-specific) On A7x GPUs: - every time the number of concurrent local groups exceeds a multiple of 64, there is a potential performance impact. If the shader spends a significant amount of time stalled, then the performance impact may occur for each multiple of 128 concurrent local groups - there is another potential performance impact when the number of concurrent local groups exceeds a multiple of 2048 On A7x GPUs, every time the number of workgroups exceeds a multiple of 16 there is a potential performance impact. This multiple is 8 if the shaders read each others’ memory ## [Mesh Shaders](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-mesh-shading-best-practices) [VkPipelineShaderStageRequiredSubgroupSizeCreateInfo::requiredSubgroupSize](https://registry.khronos.org/vulkan/specs/latest/man/html/VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT.html) has an optimal number of waves to specify – exceeding this number may incur a performance bottleneck, while passing a smaller number won’t fully utilize the Gpu. On A7x and A8x, this number is 64. On A7x and A8x, every time a mesh shader payload exceeds a multiple of 32kB, there is a potential performance impact. The mesh payload is calculated: - PerPrimitiveIndexNum is 3 (for TRIANGLES topology) or 2 (for LINES topology) - MaxVerticesNum and MaxPrimitiveNum should be presumed to be 256, since they cannot be higher ([ideally PrimitiveAttributeByteNum is 0](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-prefervertexattributestoprimitiveattributes)) - MeshShaderDataPayloadSize = MaxPrimitivesNum \* sizeof(uint32) \* PerPrimitiveIndexNum + MaxVerticesNum \* VertexAttributeBytesNum + MaxPrimitivesNum \* PrimitiveAttributeBytesNum ## [Raytracing](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-raytracing-best-practices) Each invocation of [vkCmdBuildAccelerationStructuresKHR](https://registry.khronos.org/vulkan/specs/latest/man/html/vkCmdBuildAccelerationStructuresKHR.html) or [vkCmdBuildAccelerationStructuresIndirectKHR](https://registry.khronos.org/vulkan/specs/latest/man/html/vkCmdBuildAccelerationStructuresIndirectKHR.html) has an optimal number of acceleration structures to build – exceeding this number may incur a performance bottleneck, while passing a smaller number won’t fully utilize the Gpu. On A8x, this number is 32. The optimal ray query subgroup size on A8x is 64 (see [VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT::requiredSubgroupSize](https://registry.khronos.org/vulkan/specs/latest/man/html/VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT.html)) ## [Queries](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-queries) ### [Occlusion queries](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-occlusion-query-correct-usage) On A5x GPUs, no more than 512 [occlusion queries](https://docs.qualcomm.com/doc/80-78185-2/topic/mobile_best_practices.html#mobile-occlusion-query-correct-usage) should be active.
