AMDATI Radeon HD 5770 Specifications
ATI Radeon HD 5770 GPU Core
Shader units and compute resources
The ATI Radeon HD 5770 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 HD 5770 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the ATI Radeon HD 5770'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 HD 5770 by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's ATI Radeon HD 5770 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The ATI Radeon HD 5770'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 HD 5770 by AMD Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the ATI Radeon HD 5770, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.
ATI Radeon HD 5770 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the ATI Radeon HD 5770 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.
TeraScale 2 Architecture & Process
Manufacturing and design details
The ATI Radeon HD 5770 is built on AMD's TeraScale 2 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 HD 5770 will perform in GPU benchmarks compared to previous generations.
AMD's ATI Radeon HD 5770 Power & Thermal
TDP and power requirements
Power specifications for the ATI Radeon HD 5770 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 HD 5770 to maintain boost clocks without throttling.
ATI Radeon HD 5770 by AMD Physical & Connectivity
Dimensions and outputs
Physical dimensions of the ATI Radeon HD 5770 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’s ATI Radeon HD 5770 is built on TSMC’s 40 nm process as part of the Evergreen (HD 5700) generation, using the Juniper chip and TeraScale 2 architecture. It was released on 2009-10-12, and its sole database benchmark entry is a Geekbench OpenCL score of 1190, placing it at the 4th percentile among all GPUs. The card has 1024 MB of GDDR5 on a 128-bit bus, with 800 shading units, 40 TMUs, 16 ROPs, and 76.80 GB/s of memory bandwidth. It was introduced at a launch MSRP of 159 USD.
Who Should Consider It
With a 4th-percentile ranking, the HD 5770 sits in the lower part of the tracked GPU pool. Its average benchmark score of 1190 is effectively at parity with the AMD Radeon HD 7650M, which scores 1192. Users with OpenCL workloads that require only modest compute throughput should consider this card; those targeting higher overall GPU performance should look above this percentile band.
The memory subsystem sets the practical settings ceiling. The 1024 MB memory capacity, 128-bit bus, and 76.80 GB/s bandwidth limit how much texture data can be moved at once. To stay within that capacity, users should keep resolution moderate and reduce texture-heavy settings rather than pushing to the highest quality presets. The 13.60 GPixel/s pixel rate and 34.00 GTexel/s texture rate are the corresponding fixed-function throughput limits, meaning fill-rate-bound scenarios will not have much extra headroom.
The physical and power requirements are modest. The card is a dual-slot design, 208 mm (8.2 inches) long, with a 108 W TDP, a 1x 6-pin power connector, and a 300 W suggested PSU. It uses PCIe 2.0 x16. These specifications make it suitable for systems that can supply the 6-pin power connector and physically fit a dual-slot card.
How It Compares
AMD Radeon HD 7650M — This closest rival has an average score of 1192. The HD 5770 trails it by 0.2%, which is effectively a tie. No other competitor in the nearest-rival set is closer.
ATI Mobility Radeon HD 5570 — This rival scores 1186. The HD 5770 leads it by 0.3%, a marginal advantage that keeps the two cards in the same performance class.
NVIDIA Quadro M600M — The Quadro M600M averages 1179. The HD 5770 is 0.9% ahead, again a small but measurable edge.
AMD FirePro M2000 — The FirePro M2000 averages 1168. The HD 5770 leads it by 1.9%, the largest gap among the nearest rivals. Even so, the entire rival group is tightly clustered.
Ray Tracing and Feature Set
The HD 5770 has no ray tracing cores and no tensor cores listed. Its compute and graphics resources consist of 800 shading units, 40 TMUs, and 16 ROPs, with FP32 throughput of 1,360.0 GFLOPS. Its API support is DirectX 11.2 (11_0) and OpenGL 4.4; no Vulkan support is present. Display outputs are 2x DVI, 1x HDMI 1.3a, and 1x DisplayPort 1.1.
The Juniper chip is fabricated at TSMC on a 40 nm process. It contains 1,040 million transistors on a 166 mm² die, yielding a transistor density of 6.3M / mm². In the product sequence, the HD 5770 follows the Radeon R700 generation and is succeeded by Northern Islands. Production status is end-of-life.

Benchmark Performance
The HD 5770’s benchmark result is a single Geekbench OpenCL score of 1190. Because its percentile standing is 4, only 4% of all GPUs in the database have lower scores. This is a low position, but the nearest rival cluster shows how narrow the competition is at this level. The HD 5770 is 0.2% behind the AMD Radeon HD 7650M (score 1192), 0.3% ahead of the ATI Mobility Radeon HD 5570 (score 1186), 0.9% ahead of the NVIDIA Quadro M600M (score 1179), and 1.9% ahead of the AMD FirePro M2000 (score 1168).
The deltaPct values therefore range from -0.2 to 1.9. Only one rival has a higher average score, and that advantage is just 0.2%. The three lower rivals are all within 1.9% of the HD 5770. This means that in OpenCL compute work, the HD 5770 will behave essentially like its nearest neighbors, with no large performance separation between any of the five cards.
The fixed-function throughput figures support this assessment: 13.60 GPixel/s pixel rate, 34.00 GTexel/s texture rate, and 1,360.0 GFLOPS FP32. The 76.80 GB/s memory bandwidth is the data rate feeding the 800 shading units. Taken together, the 1190 score, the 4th-percentile rank, and the tight deltaPct values describe a GPU that is low-ranked overall but firmly embedded in a close performance cluster.
