AMDAMD Radeon HD 7730 Specifications
Radeon HD 7730 GPU Core
Shader units and compute resources
The AMD Radeon HD 7730 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.
HD 7730 Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the Radeon HD 7730'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 Radeon HD 7730 by AMD dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
AMD's Radeon HD 7730 Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The Radeon HD 7730'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.
Radeon HD 7730 by AMD Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the HD 7730, 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.
HD 7730 Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the AMD Radeon HD 7730 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.
GCN 1.0 Architecture & Process
Manufacturing and design details
The AMD Radeon HD 7730 is built on AMD's GCN 1.0 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 HD 7730 will perform in GPU benchmarks compared to previous generations.
AMD's Radeon HD 7730 Power & Thermal
TDP and power requirements
Power specifications for the AMD Radeon HD 7730 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 Radeon HD 7730 to maintain boost clocks without throttling.
Radeon HD 7730 by AMD Physical & Connectivity
Dimensions and outputs
Physical dimensions of the AMD Radeon HD 7730 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.

No benchmark data available for this GPU.
About AMD Radeon HD 7730
The AMD Radeon HD 7730 is a 28 nm GCN 1.0 part built on the Cape Verde chip, belonging to the Southern Islands (HD 7700) generation; its launch MSRP was 59 USD. The fact pack records a 50th-percentile position among all GPUs in the database, but the average benchmark score is 0 and the benchmarks array is empty. This makes the theoretical specifications the primary basis for interpretation, alongside the power envelope, memory subsystem, and API feature set.
Power and Cooling
The Radeon HD 7730 is a low-power design by the numbers in the fact pack. Its TDP is 47 W, and the suggested PSU is 200 W. That combination implies a small, modest system power draw, though the exact platform power outside the card is not given. The card is single-slot and has no power connectors, so it does not require auxiliary PCIe power cabling. The PCIe 3.0 x16 bus interface would provide the electrical connection and data path, and with no extra connectors the installation procedure is simplified.
Physical dimensions are listed as 168 mm, or 6.6 inches, in length. The fact pack does not include height or width, so the full mechanical footprint remains unspecified. What the data does show is a card that should fit typical low-profile? No, the fact pack only states length, not profile. The single-slot designation is separate from low-profile status. The absence of power connectors and a 200 W suggested PSU suggests this is not a card that stresses a power supply. For systems near that 200 W recommendation, the HD 7730’s 47 W TDP is the relevant upper bound for the card itself.
Ray Tracing and Feature Set
Dedicated ray tracing hardware is not present in the fact pack. The entries for RT cores and tensor cores are both null, meaning no such units are listed for this GPU. The feature set is instead defined by GCN 1.0, the Southern Islands generation, and the Cape Verde chip layout: 384 shading units, 24 texture mapping units, and 8 ROPs. The FP32 compute rate is 614.4 GFLOPS, which is the single-precision floating-point throughput listed for the card.
API support in the fact pack includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX entry carries the feature level 11_1, which indicates a specific feature tier rather than full DirectX 12 hardware feature parity. OpenGL 4.6 and Vulkan 1.2.170 show that modern API entry points may be available, but the fact pack does not describe specific extension behavior. Display connectivity consists of 1x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. Those outputs support conventional display attachment, but the fact pack provides no maximum resolution or refresh rate data.
Because RT cores and tensor cores are absent, ray tracing and tensor-accelerated workloads are not represented in the feature set. The available compute resources are the 384 shading units and the FP32 rate of 614.4 GFLOPS. The API list still makes this an interesting card to examine: it spans older DirectX 11_1-era expectations and newer Vulkan/OpenGL entries.
Benchmark Performance
This is the most unusual part of the data. The benchmarks array is empty, and the average benchmark score is 0. That is not a score meaning zero performance; rather, the fact pack contains no individual benchmark results from which an average could be calculated. The only positional metric is percentileVsAllGpus: 50. That places the HD 7730 at the midpoint of the database’s GPU distribution. In other words, half of all GPUs in the database rank above it and half rank below, assuming the percentile is computed from a full distribution. But because the average benchmark score is 0, the percentile cannot be cross-verified against an actual aggregate score.
Nearest rivals are also absent: the nearestRivals array is empty. Consequently, there are no deltaPct values, no rival names, and no percentage comparisons to cite. Benchmark interpretation therefore falls back on the theoretical peak rates. The pixel fill rate is 6.400 GPixel/s, the texture fill rate is 19.20 GTexel/s, and the FP32 rate is 614.4 GFLOPS. These are upper bounds, not observed frame rates, but they define the card’s compute ceiling. A 50th-percentile card with 384 shaders, 8 ROPs, and 72.00 GB/s of memory bandwidth fits the profile of an entry-level or legacy-oriented product. The data does not support a claim that it outperforms any specific rival, because no rival data is present.

Who Should Consider It
The HD 7730 is an end-of-life part, so it is not a current-generation recommendation. The data suggests a specific niche: a low-power, single-slot card with a 200 W PSU requirement and no auxiliary power connectors. A system with limited power delivery could use this card without additional cabling. The 1024 MB GDDR5 frame buffer and 72.00 GB/s bandwidth point toward lower resolutions and lighter settings rather than high-resolution, high-detail gaming. At higher resolutions, the 1 GB capacity could become a constraint because large textures and intermediate buffers compete for that space.
The theoretical fill rates reinforce this: 6.400 GPixel/s and 19.20 GTexel/s are not high-end numbers. For users seeking a simple display output card, the combination of one DVI, one HDMI 1.4a, and one DisplayPort 1.2 output is useful. For users expecting modern ray tracing or tensor-heavy workloads, the fact pack shows no such hardware. The 50th-percentile rank places it in the middle of the database, but the empty benchmark array means no measured game performance is available to validate a specific settings recommendation. Therefore, the practical answer is: consider it for lower-resolution use, legacy builds, or basic display attachment, not for demanding modern workloads.
Memory Subsystem
The memory subsystem is precisely defined in the fact pack: 1024 MB of GDDR5, a 128-bit bus, and 72.00 GB/s of bandwidth. The memory clock is listed as 1125 MHz with 4.5 Gbps effective data rate. The 128-bit bus width is a moderate interface, and 72.00 GB/s is the resulting bandwidth ceiling. For a 47 W card, that bandwidth must be balanced against the GPU’s 614.4 GFLOPS compute rate. The pixel rate of 6.400 GPixel/s and texture rate of 19.20 GTexel/s are both likely to be influenced by how quickly data can move through this 128-bit memory path.
At high resolutions, the 1 GB capacity is the more immediate limitation. A 1024 MB frame buffer can fill quickly with color buffers, depth data, and texture caches. The 72.00 GB/s bandwidth is the maximum rate at which those bytes can be read or written. The fact pack does not provide measured memory benchmark scores, so the data allows structural analysis but not tested performance. Still, the relationship is clear: a 128-bit bus and 1024 MB GDDR5 configuration is designed for efficiency within a low-power envelope, not for massive memory throughput. The effective 4.5 Gbps memory rate is the rate at which each data pin operates, and across 128 pins it yields the stated 72.00 GB/s. That is a modest but internally consistent memory design.
How It Compares
The nearestRivals array in the fact pack is empty. There are no rival names, scores, or deltaPct values to compare. As a result, this section cannot provide the usual rival-by-rival percentage analysis. The only positional indicator is percentileVsAllGpus: 50, which places the HD 7730 at the midpoint of the database distribution. No specific competitor is named above or below it. The predecessor and successor fields identify Northern Islands and Sea Islands as the surrounding generations, but neither is associated with a score in the fact pack.
Without nearest rivals, a direct comparison to another GPU is not possible from this data. The theoretical rates, 614.4 GFLOPS FP32, 19.20 GTexel/s texture fill, 6.400 GPixel/s pixel fill, can serve as reference points, but they are not rival deltas. This absence of rival data is itself informative: the HD 7730’s database entry is specification-heavy and measurement-light. The 50th percentile is the single comparative statement available, and it is a broad one.
