AMD Radeon HD 8570A

The AMD Radeon HD 8570A is a 28 nm GCN 1.0 part built by AMD at TSMC, integrating 690 million transistors into a 56 mm² die with a transistor density of 12.3M / mm². It belongs to the All-In-One (HD 8000) generation and is built around the Sun chip. The product is packaged as an MXM Module using the MXM-A (3.0) bus interface, and its display outputs are listed as Portable Device Dependent. The production status is End-of-life, with a release date of 2013-02-28.

Memory Subsystem

The memory subsystem consists of 1024 MB of DDR3 on a 64 bit bus. The memory clock is 1000 MHz, giving a 2 Gbps effective data rate and a total bandwidth of 16.00 GB/s. This is a compact configuration: the bus width is narrow, and the capacity is limited to 1 GB, so the memory system is small both in footprint and in total data movement capability.

For high-resolution work, the 1024 MB frame buffer is the first constraint. A large color buffer, depth buffer, and additional render targets can consume a substantial portion of the available capacity before the GPU's computation limits are reached. The 64 bit interface also bounds how quickly textures and geometry can be streamed into the chip. Even though the shading units are capable of 528.0 GFLOPS of FP32 compute, the 16.00 GB/s memory bandwidth is a separate ceiling that cannot be raised by compute throughput.

The pixel fill rate is 6.600 GPixel/s and the texture fill rate is 16.50 GTexel/s. These fill rates show that the 8 ROPs and 20 TMUs can output pixels and texels at a steady pace, but every pixel written and every texel fetched must traverse the memory bus. As resolution increases, the number of fragments and texels grows, and the pressure on the 16.00 GB/s bus rises accordingly. The data suggests that, for this GPU, high-resolution performance is more likely to be limited by memory capacity and bandwidth than by raw shader throughput.

Ray Tracing and Feature Set

The specification record lists no RT cores and no tensor cores. There is, therefore, no dedicated ray tracing hardware and no dedicated tensor/AI acceleration block in this GPU. The compute resources are the 320 shading units, along with 20 texture units and 8 ROPs. The architecture is GCN 1.0, which is the underlying design that the API support is built on.

API support includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 entry is qualified with the 11_1 feature level, so the software API can be exposed as DirectX 12 while the hardware feature level remains 11_1. The OpenGL 4.6 and Vulkan 1.2.170 entries provide the supported interface versions for applications using those APIs. With no RT cores or tensor cores listed, any ray tracing or AI-oriented workload would have to run through the standard shading pipeline of the chip rather than through dedicated hardware blocks.

Benchmark Performance

The benchmark records for the AMD Radeon HD 8570A are empty. The benchmarks array contains no entries, and the avgBenchmarkScore field is 0. Consequently, there is no measured average performance score to report for this GPU. The only positional field is percentileVsAllGpus, which is 50. That places the GPU at the 50th percentile of all GPUs in the database.

Because the average score is 0 and the benchmark list is empty, the 50th percentile value cannot be tied to a specific averaged benchmark result. It is the sole positional number in the record, but it is not accompanied by an actual score. The nearestRivals array is also empty: there are no rival names, no rival scores, and no deltaPct values. No percentage comparison can be constructed from the data, and no rival positioning is possible based on measured workloads.

The performance envelope of the GPU must therefore be described from its internal specifications rather than from benchmark deltas. The chip is rated for 528.0 GFLOPS of FP32 compute, 6.600 GPixel/s of pixel fill, and 16.50 GTexel/s of texture fill, all backed by 16.00 GB/s of memory bandwidth. Those figures define what the hardware is capable of in absolute terms, but the absence of benchmark scores means there is no external measurement from the database to validate or rank that capability.

How It Compares

The nearestRivals data for this GPU is empty. No rival names, scores, or deltaPct values are present in the record, so a per-rival position cannot be described. The only relative value is percentileVsAllGpus of 50, which places the GPU at the midpoint of all GPUs in the database; however, with an empty benchmarks array and an average score of 0, that percentile is not supported by a measured benchmark average.

In the absence of rival entries, the GPU's position can only be characterized by its own specifications. The 320 shading units and 528.0 GFLOPS FP32 throughput sit alongside 6.600 GPixel/s pixel fill and 16.50 GTexel/s texture fill. The 16.00 GB/s memory bandwidth and 1024 MB capacity are the other half of the envelope. Taken together, the data shows a part whose compute and fill capabilities are paired with a narrow memory interface, making the memory subsystem the most distinguishing part of the specification.
