AMDAMD Stream Processor Specifications
GPU Core
Shader units and compute resources
The AMD Stream Processor 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.
Stream Processor Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Stream Processor'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 Stream Processor by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's Stream Processor Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Stream Processor'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.
Stream Processor Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the AMD Stream Processor 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.
Ultra-Threaded SE Architecture & Process
Manufacturing and design details
The AMD Stream Processor is built on AMD's Ultra-Threaded SE 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 Stream Processor will perform in GPU benchmarks compared to previous generations.
Power & Thermal
TDP and power requirements
Power specifications for the AMD Stream Processor 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 Stream Processor to maintain boost clocks without throttling.
Stream Processor by AMD Physical & Connectivity
Dimensions and outputs
Physical dimensions of the AMD Stream Processor are critical for case compatibility. Card length, height, and slot width determine whether it fits in your chassis. The PCIe interface version affects bandwidth for communication with the CPU. Display outputs define monitor connectivity options, with modern cards supporting multiple high-resolution displays simultaneously. Verify these specifications against your case and motherboard before purchasing to ensure a proper fit.
AMD API Support
Graphics and compute APIs
API support determines which games and applications can fully utilize the AMD Stream Processor. DirectX 12 Ultimate enables advanced features like ray tracing and variable rate shading. Vulkan provides cross-platform graphics capabilities with low-level hardware access. OpenGL remains important for professional applications and older games. CUDA (NVIDIA) and OpenCL enable GPU compute for video editing, 3D rendering, and scientific applications. Higher API versions unlock newer graphical features in GPU benchmarks and games.
Stream Processor Product Information
Release and pricing details
The AMD Stream Processor is manufactured by AMD as part of their graphics card lineup. Release date and launch pricing provide context for comparing GPU benchmark results with competing products from the same era. Understanding the product lifecycle helps evaluate whether the Stream Processor by AMD represents good value at current market prices. Predecessor and successor information aids in tracking generational improvements and planning future upgrades.
About AMD Stream Processor
AMD Stream Processor is an end-of-life graphics card built around the R580 chip. Its architecture is Ultra-Threaded SE, and TSMC fabricates the chip on a 90 nm process. The die contains 384 million transistors on a 352 mm² surface, which works out to 1.1M transistors per mm². The card carries 1024 MB of GDDR3 memory across a 256-bit bus, delivering 41.47 GB/s of memory bandwidth. API support is recorded as DirectX 9.0c (9_3), OpenGL 2.1 (full), and OpenGL 3.0 (partial), with no Vulkan support listed. The database places the card at the 50th percentile of all GPUs, but no nearest rivals and no individual benchmark scores accompany the entry.
How It Compares
The nearestRivals record for the AMD Stream Processor is empty. This means the data set provides no named competitor cards, no rival benchmark scores, and no deltaPct values to quantify performance gaps. Without those entries, relative positioning against a specific card is not available. The only global comparison field is percentileVsAllGpus, which is 50. That places the card at the exact midpoint of the tracked GPU population in the database. The specification does not provide enough data to say which cards sit just above or below it.
The product lineage is recorded as Rage GL for the predecessor and FireGL for the successor. No performance figures are listed for either card, so the lineage cannot be used to infer generational gains. The database entry is also marked as end-of-life, but that status does not carry a rival comparison. In short, the comparison section is defined by absence: no nearest rivals, no deltas, and no individual workloads.
Ray Tracing and Feature Set
The AMD Stream Processor has no RT cores and no tensor cores in its recorded specification. There is no dedicated ray tracing hardware to accelerate ray intersection or traversal work. Similarly, there is no tensor core block for matrix-based workloads. The feature set is therefore focused on the traditional fixed-function pipeline and the Ultra-Threaded SE architecture.
API support is anchored to the DirectX 9 generation. The card supports DirectX 9.0c (9_3), OpenGL 2.1 (full), and OpenGL 3.0 (partial). Vulkan support is not listed. This is a feature set intended for an older software ecosystem rather than modern low-level APIs. Display output is limited to 2x DVI and 1x S-Video, with no digital display types beyond DVI recorded.
The memory subsystem consists of 1024 MB of GDDR3 on a 256-bit bus. Memory speed is 648 MHz, with 1296 Mbps effective transfer rate. The bus provides 41.47 GB/s of peak bandwidth. The graphics pipeline is built around 16 texture mapping units and 16 raster output units. The recorded pixel rate is 9.504 GPixel/s, and the recorded texture rate is 9.504 GTexel/s.
The chip itself is produced on a 90 nm process at TSMC. It uses 384 million transistors, giving a transistor density of 1.1M per mm². The interface is PCIe 1.0 x16. No shading unit count, FP32 throughput, or FP16 throughput is recorded in the data, so the architectural feature set can only be described from the fixed-function rates and memory specifications.
Benchmark Performance
The benchmark data for the AMD Stream Processor is minimal. The average benchmark score is recorded as 0, and no individual benchmark entries are listed. The percentileVsAllGpus field is 50, which means the card sits at the median of the database's GPU distribution. Because no workloads are attached to the score, the 0 value cannot be broken down into gaming, compute, or synthetic results.
There are no nearestRivals entries, so there are no deltaPct values to express how much faster or slower this card is than adjacent products. The raw throughput figures provide the only concrete performance anchors. The card rasterizes at 9.504 GPixel/s and textures at 9.504 GTexel/s. These two rates are identical, reflecting a balanced combination of 16 ROPs and 16 TMUs at the specification level.
Memory bandwidth is 41.47 GB/s, carried over a 256-bit GDDR3 interface. The memory clock is 648 MHz, and the effective rate is 1296 Mbps. No base, boost, or game clock is listed for the processor itself; the only recorded clock belongs to memory. No FP32 or FP16 throughput values are provided, which limits any analysis of compute performance.
The 50th percentile is the only relative benchmark ranking in the entry. It indicates a middle-of-the-pack position across all GPUs in the database, but with no rival scores and no workload scores, that ranking is not supported by a visible performance distribution. The pixel rate, texture rate, and memory bandwidth are the numbers that define the card's practical throughput, while the lack of benchmark scores prevents a more detailed performance interpretation.
Power and Cooling
The AMD Stream Processor has a TDP of 165 W. The suggested power supply is 450 W. Power is supplied through a single 1x 6-pin PCIe power connector. No other power connector types are recorded.
The card occupies a dual-slot footprint. Its length is 241 mm, which is 9.5 inches, and its height is 111 mm, which is 4.4 inches. The bus interface is PCIe 1.0 x16. The production status is end-of-life. The cooling solution is defined by the dual-slot width, but the data set does not describe the cooler type, fan count, or heatsink design beyond that footprint. The power specification is straightforward: a 165 W card with a 450 W supply recommendation and one 6-pin connector.
