About AMD Radeon HD 8590M
How It Compares
The AMD Radeon HD 8590M occupies a narrow performance band, sitting at the 50th percentile among all GPUs in the database. This places it in the middle of the pack, a position that reflects its modest specifications rather than any standout capability. With no direct rivals listed in the benchmark data, the comparison must rely on architectural context and raw throughput figures to frame its standing.
The GPU's 528.0 GFLOPS of FP32 compute and 36.00 GB/s of memory bandwidth are consistent with an entry-level discrete part from its generation. The 64-bit memory bus, paired with GDDR5 at 4.5 Gbps effective, limits data throughput to a level that would struggle with modern high-resolution textures. In practice, this means 1080p gaming at medium settings would be the realistic ceiling, with frame rates likely dipping below 30 FPS in demanding titles.
The 8 ROPs and 20 TMUs are sparse by today's standards. Pixel fill rate of 6.600 GPixel/s and texture rate of 16.50 GTexel/s indicate that the card can handle basic rasterization but will bottleneck on shader-heavy effects or high-detail geometry. The 320 shading units, running at a boost clock of 825 MHz, provide enough compute for older DirectX 11 titles but fall short in Vulkan or DX12 workloads that leverage async compute.
Ray Tracing and Feature Set
The HD 8590M has no dedicated ray tracing cores and no tensor cores. This is a pure rasterization GPU, built on the GCN 1.0 architecture at a 28 nm process node by TSMC. The chip, codenamed Sun, packs 690 million transistors into a 56 mm² die, yielding a transistor density of 12.3M per mm². While this density is respectable for its era, it does not include any hardware acceleration for ray-traced lighting, shadows, or reflections.
API support is the most forward-looking aspect of this GPU. It supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 feature level of 11_1 means it can run DX12 titles but without the full feature set of higher-tier hardware. Vulkan 1.2.170 support is notable, as it allows the card to run modern Vulkan-based engines, though performance will be limited by the underlying hardware. OpenGL 4.6 ensures compatibility with a wide range of professional and legacy applications.
The absence of tensor cores means no AI-accelerated features like DLSS or any form of hardware-accelerated machine learning inference. Similarly, the lack of RT cores precludes any hardware ray tracing, so any ray-traced effects would have to be computed on the shading units, which would be impractically slow given the 528.0 GFLOPS of FP32 throughput.
Power and Cooling
The FACT PACK does not list a TDP, slot width, power connector requirement, or a suggested PSU rating for this GPU. Without those figures, the analysis must note that the card's power draw is not specified in the available data. Given the 28 nm process and the modest specs, one can infer that power consumption is low enough to not require auxiliary PCIe power connectors, but this is not confirmed by the data.
The bus interface is PCIe 3.0 x8, which halves the lane count compared to a full x16 slot. For a GPU of this performance class, the bandwidth reduction is unlikely to be a bottleneck, as the 36.00 GB/s memory bandwidth is far lower than what even a PCIe 3.0 x4 link could provide. Cooling requirements are also unspecified, but the lack of a TDP figure suggests that the card was designed for thin-and-light laptops or low-profile desktop implementations.
The production status is listed as end-of-life, and the release date is February 28, 2013. This places it in the early days of the GCN architecture, before AMD refined power management in later iterations. The predecessor is listed as "London" and the successor as "Gem System," indicating a clear generational progression within AMD's mobile GPU lineup.

Benchmark Performance
The benchmark data for the HD 8590M is sparse — the average benchmark score is 0, and the nearestRivals array is empty. The percentileVsAllGpus field shows 50, meaning the GPU sits exactly at the median of all GPUs in the database. This is a curious position, as a score of zero with no rival comparisons suggests the card may not have been subjected to the standard benchmark suite, or that its performance is so low that it fails to register meaningful scores.
Without direct rival scores, the analysis must rely on the theoretical throughput figures. The FP32 compute of 528.0 GFLOPS is roughly one-third of what a mid-range GPU from the same era would offer. The texture rate of 16.50 GTexel/s and pixel rate of 6.600 GPixel/s are similarly constrained. In synthetic benchmarks like 3DMark Fire Strike, this card would likely score in the low thousands, but the exact numbers are absent from the FACT PACK.
The memory subsystem is a critical bottleneck. With a 64-bit bus and 36.00 GB/s bandwidth, the card is severely limited in bandwidth-bound scenarios. Modern games often require several times this bandwidth even at 720p. The 1024 MB frame buffer is also restrictive, as many contemporary titles exceed 2 GB of VRAM usage at medium settings.
The lack of benchmark scores and rival comparisons means that any percentage-based performance analysis is impossible. The data shows only the 50th percentile ranking, which is a broad indicator rather than a precise measurement. If this GPU were benchmarked, it would likely trail dedicated desktop parts from the same generation by a wide margin, but the exact deltas are not available in the FACT PACK.
In summary, the HD 8590M is a low-end mobile GPU from 2013, built on GCN 1.0 with 320 shading units. Its 50th percentile ranking appears generous given the specifications, but without concrete benchmark scores or rival comparisons, the performance picture remains incomplete. The card's legacy is one of basic 1080p gaming at low settings, with API support that outlived its hardware capabilities. The data indicates a GPU that was entry-level at launch and has not aged gracefully, but the absence of test scores prevents a definitive quantitative verdict.
