AMDATI Radeon X550 Specifications
ATI Radeon X550 GPU Core
Shader units and compute resources
The ATI Radeon X550 GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
ATI Radeon X550 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the ATI Radeon X550's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The ATI Radeon X550 by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's ATI Radeon X550 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The ATI Radeon X550's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
ATI Radeon X550 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the ATI Radeon X550 against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.
R300 Architecture & Process
Manufacturing and design details
The ATI Radeon X550 is built on AMD's R300 architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the ATI Radeon X550 will perform in GPU benchmarks compared to previous generations.
AMD's ATI Radeon X550 Power & Thermal
TDP and power requirements
Power specifications for the ATI Radeon X550 determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the ATI Radeon X550 to maintain boost clocks without throttling.

About ATI Radeon X550
ATI Radeon X550 is an end-of-life graphics card from AMD, based on the RV370 chip and the R300 architecture. The database places it in the Radeon R300 (X550) generation, with a 110 nm TSMC process, 107 million transistors, a 74 mm² die, and a transistor density of 1.4M per mm². It uses a PCIe 1.0 x16 bus interface and is a single-slot card. Its release date is 2005-06-30, and its production status is end-of-life. The series field is null, so the card is not assigned to a named product series in this record. In lineage terms, the predecessor is Radeon R200 and the successor is Radeon R400 AGP.
Power and Cooling
The fact pack does not list a TDP for the ATI Radeon X550. The only PSU guidance is a 200 W suggested PSU, and the card has no power connectors. Because the powerConnectors field is "None", all power is expected to come through the PCIe 1.0 x16 slot. The slot form factor is the only power delivery interface specified; no auxiliary connectors are present. The card's slot width is single-slot, so it occupies one expansion slot. The physical dimensions are not recorded: length, height, and width fields are all null, so no clearance analysis is possible.
The 110 nm process, 107 million transistor count, and 74 mm² die size describe the integration level. The density is 1.4M transistors per square millimeter, which is a direct arithmetic expression of those figures. At this process and die size, the data does not state a power draw; the only power-system number is the 200 W suggested PSU. The absence of power connectors and the 200 W figure together indicate a low-power installation profile, but the fact pack does not contain an explicit wattage to confirm that. Therefore, the power section is best summarized as: no TDP, no auxiliary connectors, a 200 W PSU recommendation, and single-slot cooling.
Ray Tracing and Feature Set
The Radeon X550 has no listed ray tracing cores: rtCores is null. It also has no tensor cores: tensorCores is null. The API support is DirectX 9.0 and OpenGL 2.0, with no Vulkan entry. These API versions are the only software feature boundaries from the fact pack. The absence of Vulkan support means applications that require Vulkan are outside the card's feature set. No RT or tensor functionality is described in any field.
Fixed-function rasterization resources are present: 4 texture mapping units and 4 render output units. The resulting pixel rate is 1.600 GPixel/s and the texture rate is 1.600 GTexel/s. The shadingUnits, fp32, and fp16 fields are null, so no shader throughput figures exist. The architecture name is listed as R300 and the chip as RV370, but the feature set is defined by the API and fixed-function rates above. The database does not provide any geometry-processing or tessellation-specific facts. In short, this is a rasterization-oriented specification with no ray tracing, no tensor compute, and no Vulkan support; DirectX 9.0 and OpenGL 2.0 are the only API facts available.
Memory Subsystem
The memory subsystem consists of 128 MB of DDR memory on a 128-bit bus. The memory clock is 250 MHz, and the effective data rate is 500 Mbps. The listed bandwidth is 8.000 GB/s. The relationship between these numbers is direct: a 128-bit bus at an effective DDR rate produces the stated 8.000 GB/s aggregate bandwidth.
For high resolutions, the memory size is the first constraint. A 128 MB buffer cannot hold very large color and depth buffers together with large texture sets; the fact pack does not mention any memory compression or caching technique. The second constraint is bandwidth: 8.000 GB/s must serve all memory traffic. With only 4 TMUs and 4 ROPs, the pixel and texture rates are 1.600 GPixel/s and 1.600 GTexel/s, meaning memory traffic is likely to be heavy relative to those fixed-function rates. The 128-bit bus width is balanced against the memory size, but the effective data rate is the deterministic limit of this DDR memory. The fact pack does not include high-resolution scores, so the exact impact on resolution scaling is not quantified.
Who Should Consider It
The Radeon X550 has no benchmark scores, no nearest rivals, and an average benchmark score of 0. Consequently, recommendations must be based on the specification list rather than measured performance. The DirectX 9.0 and OpenGL 2.0 API support makes it a match for software written to those API generations. The 128 MB memory capacity and 8.000 GB/s bandwidth point to low-resolution rendering with conservative texture settings. The output set of 1x DVI, 1x VGA, and 1x S-Video supports one digital display plus analog and television-out uses.
Users with a 200 W PSU and a PCIe 1.0 x16 slot can satisfy the basic installation requirements. The card has no power connectors, so no extra cables are required. The single-slot footprint is a minimal mechanical requirement. Because the production status is end-of-life, ongoing support should not be expected. The absence of Vulkan support and the null RT/tensor core fields exclude applications built on those newer APIs. The display outputs also suggest a DVI desktop with an analog VGA or S-Video secondary output, rather than a high-resolution multi-monitor setup. The data does not include any settings-based recommendations; the specification envelope itself is the only guide.
Benchmark Performance
The benchmark record for the ATI Radeon X550 is empty. The benchmarks array has no entries, nearestRivals is empty, and avgBenchmarkScore is 0. As a result, no exact percentage deltas against rival cards can be reported; there are no scores to compare. The percentileVsAllGpus value is 50, which places the card at the midpoint of the database in a flat sense. Yet with an average score of zero and no benchmark submissions, that 50th percentile is not backed by measured runs. It is a metadata position, not a validated performance result.
The only quantitative performance indicators are the fill rates. The 4 ROPs produce 1.600 GPixel/s, and the 4 TMUs produce 1.600 GTexel/s. These values are equal, indicating symmetric pixel and texture throughput in a fill-rate-bound scenario. The base/boost/game clock fields are null, so clock-rate-based analysis is impossible. The shadingUnits, fp32, and fp16 fields are null, so compute throughput cannot be derived.
In relation to the predecessor and successor, the fact pack supplies names only. Radeon R200 is the predecessor and Radeon R400 AGP is the successor. No scores exist for either, so no generation-to-generation percentage change can be calculated. The database therefore provides no way to position the X550 against any named rival product. The 50th percentile field should be interpreted with caution: it is the only ranking-like number, but it is attached to an average score of zero. Without nearestRivals deltas, the benchmark section is a statement of missing data rather than an evaluation of measured performance.
