About ATI Radeon HD 4580
The ATI Radeon HD 4580 is a compact, end-of-life graphics card from AMD, built on the 55 nm TeraScale architecture with the RV635 chip. Positioned within the Radeon R700 (HD 4500) generation, this single-slot card offers a baseline set of specifications designed for fundamental 3D acceleration and media output. This analysis presents the benchmark data, comparative positioning, power requirements, and feature set based solely on the provided fact pack.
Benchmark Performance
The data indicates that the ATI Radeon HD 4580 holds a 50th percentile ranking when compared to all GPUs in the database, placing it squarely in the middle of the performance spectrum. The average benchmark score is recorded as 0, which suggests that no standardized benchmark results are available for this specific model in the current dataset. Consequently, direct performance measurements are absent, and analysis must rely on the card's theoretical specifications and architectural characteristics.
The fundamental processing capabilities are derived from its 120 shading units, 8 texture mapping units, and 4 raster operation pipelines. These resources combine to deliver a pixel rate of 3.184 GPixel/s and a texture rate of 6.368 GTexel/s. The card's compute throughput is listed as 191.0 GFLOPS for FP32 operations. These figures indicate a design focused on basic resolutions and moderate graphical settings, consistent with its position as an entry-level offering in its generation. The memory subsystem consists of 512 MB of GDDR3 RAM on a 128-bit bus, providing a bandwidth of 22.18 GB/s. This memory configuration is adequate for the card's intended workload but will likely be a limiting factor in higher-resolution textures or complex scenes.
Clock speeds are specified only for the memory, operating at 693 MHz with an effective data rate of 1386 Mbps. The absence of listed core clock speeds suggests the data is incomplete or the core frequency is not a distinguishing metric for this model. The combination of a modest memory bandwidth and a limited number of ROPs suggests that fill-rate-bound scenarios will be challenging. Overall, the performance profile points to a card that supports legacy DirectX 10.1 titles at lower detail levels, rather than a high-performance gaming solution.
How It Compares
The fact pack lists no nearest rivals for the ATI Radeon HD 4580, and the benchmark scores are uniformly zero. This absence of comparative data precludes a quantitative assessment against other graphics cards. Without rival names, score deltas, or percentile comparisons, it is impossible to position this card relative to its market contemporaries or successors.
The card's predecessor is identified as the Radeon R600, and its successor is the Evergreen series. These designations provide a generational context, indicating that the HD 4580 fits between two distinct architectural families. The move from R600 to Evergreen suggests a transitional role for the TeraScale architecture implemented in this model. The data shows that the HD 4580 is at the end of its production life, meaning it would be compared against newer, more efficient architectures in any modern benchmark scenario. The lack of benchmark data and rival comparisons means that any performance hierarchy must be inferred from the specifications alone, which are indicative of a low-power, entry-level device.
Power and Cooling
The ATI Radeon HD 4580 has a thermal design power (TDP) of 65 W, classifying it as a low-power component. This modest power draw allows for a single-slot cooling solution, as indicated by the "Single-slot" designation for its physical footprint. The card requires no supplemental power connectors, drawing all its operational power directly from the PCIe 2.0 x16 slot. This simplifies installation, as no direct connections from the power supply are necessary.
For system integration, the suggested PSU rating is 250 W. This is a modest requirement that accommodates a wide range of standard desktop power supplies, even those in basic office or home systems. The card's dimensions are listed as 190 mm or 7.5 inches in length, which is a standard size that should fit in most mid-tower and full-tower cases. The combination of a 65 W TDP, no auxiliary power connectors, and a 250 W PSU recommendation makes this a straightforward upgrade for legacy systems with limited power headroom. The thermal solution is adequate for the heat generated by the 378 million transistors on the 55 nm process node, a density of 2.8M transistors per mm² on a 135 mm² die.

Ray Tracing and Feature Set
The ATI Radeon HD 4580 does not include any dedicated ray tracing cores or tensor cores, as these fields are null in the specification data. This indicates that the hardware lacks specialized acceleration for real-time ray-traced lighting effects or AI-driven features like deep learning super sampling. Any ray tracing workload, if attempted, would have to be processed by the general-purpose shading units, which are limited to 120 in number and offer 191.0 GFLOPS of FP32 compute power. This level of performance is insufficient for practical ray tracing in contemporary applications.
The feature set is further defined by its supported APIs. The card is compliant with DirectX 10.1, specifically at the 10_1 feature level, and supports OpenGL 3.3. It does not support the Vulkan API. This restricts software compatibility to older titles and applications built for these legacy interfaces. The display outputs are limited to 2x DVI and 1x S-Video, which are standard for its era but lack modern connectivity options like HDMI or DisplayPort. The memory type is GDDR3, which is older and slower than subsequent standards. In summary, the HD 4580 is a legacy product without modern features such as ray tracing, tensor core acceleration, or support for contemporary graphics APIs, positioning it as a functional but outdated component for basic display output and undemanding 3D workloads.
