PERFORMANCE BENCHMARKS
Analysis: AMD Radeon HD 7950 vs AMD Radeon RX 560 XT
The AMD Radeon RX 560 XT and the AMD Radeon HD 7950 are separated by seven years of architecture, yet their average benchmark scores place them within a hair of each other. The RX 560 XT averages 34,133, while the HD 7950 averages 33,951, a gap of just 0.5% in favor of the newer card. This near-tie makes the choice entirely dependent on what you are doing, as each card brings different strengths to the table.
Where Each One Wins
The RX 560 XT wins on raw compute throughput and modern API support. Its FP32 performance is 4.394 TFLOPS, which is 53% higher than the HD 7950's 2.867 TFLOPS. That advantage shows up in its Geekbench OpenCL score of 31,387 and Vulkan score of 36,879. The HD 7950 has no Vulkan or OpenCL scores in the data, but its single Geekbench Metal score of 33,951 shows it can still hold its own in that specific API. The RX 560 XT also has a higher pixel rate at 39.23 GPixel/s versus 25.60 GPixel/s, and a higher texture rate at 137.3 GTexel/s versus 89.60 GTexel/s. For any workload that stresses shaders or texture fill, the RX 560 XT is the clear winner.
The HD 7950 wins on memory bandwidth and board footprint. Its 384-bit bus delivers 240.0 GB/s of bandwidth, which is 7% higher than the RX 560 XT's 224.0 GB/s from a 256-bit bus. That extra bandwidth can help in scenarios where data transfers dominate, such as high-resolution texture streaming. The HD 7950 also has more physical memory capacity at 3 GB, though the RX 560 XT counters with 4 GB. In terms of physical size, the HD 7950 is longer at 278 mm (10.9 inches) and taller at 111 mm (4.4 inches), while the RX 560 XT is more compact at 241 mm (9.5 inches). The HD 7950 also has a wider profile at 38 mm (1.5 inches), which may affect case compatibility.
The architecture generation gap is stark. The RX 560 XT uses GCN 4.0 on a 14 nm process from GlobalFoundries, while the HD 7950 uses GCN 1.0 on a 28 nm process from TSMC. That process shrink allows the RX 560 XT to pack 5,700 million transistors into a 232 mm² die, achieving a density of 24.6M / mm². The HD 7950 has 4,313 million transistors on a much larger 352 mm² die, with a density of just 12.3M / mm². The RX 560 XT is more efficient in every metric, but the HD 7950 still has the bandwidth advantage.
The Verdict
If you prioritize compute performance, modern API compatibility, and efficiency, the RX 560 XT is the data-backed choice. Its 4.394 TFLOPS FP32, Vulkan 1.3 support, and DirectX 12 (12_0) capability make it more future-proof for modern games and GPGPU tasks. The 0.5% average score lead over the HD 7950 is negligible, but the wins in pixel rate, texture rate, and FP32 are substantial. The RX 560 XT also requires only one 6-pin power connector and a 450 W suggested PSU, compared to the HD 7950's two 6-pin connectors and 550 W suggested PSU.
If you need maximum memory bandwidth or a card that performs well in Metal-based workloads, the HD 7950 is the pick. Its 240.0 GB/s bandwidth is a real advantage, and its Geekbench Metal score of 33,951 shows it is still competitive in that specific API. The HD 7950 also has a higher average score than the RX 560 XT in one rival comparison: the HD 7950 is 0.5% ahead of the RX 560 XT in its own nearestRivals list, while the RX 560 XT is 0.5% ahead of the HD 7950 in its list. That symmetry highlights how close they are.
For most users, the RX 560 XT is the safer recommendation. It offers better compute, lower power draw, and a smaller footprint. The HD 7950 is only worth choosing if you specifically need that 384-bit memory bus or are locked into a Metal-only environment. Neither card is a bad choice, but the RX 560 XT's architectural advantages are hard to ignore.
Head-to-Head Benchmarks
The head-to-head benchmark array is empty, so there are no direct same-test comparisons. However, the aggregate data provides clear signals. The RX 560 XT's average score of 34,133 places it 0.5% above the HD 7950's 33,951. In the RX 560 XT's nearestRivals list, the HD 7950 appears with a deltaPct of 0.5%, meaning the RX 560 XT is 0.5% faster on average. In the HD 7950's nearestRivals list, the RX 560 XT appears with a deltaPct of -0.5%, meaning the HD 7950 is 0.5% slower. These two numbers confirm the aggregate tie.
The real separation comes from individual metrics. The RX 560 XT's FP32 of 4.394 TFLOPS is 1.527 TFLOPS higher than the HD 7950's 2.867 TFLOPS, a 53% advantage. The pixel rate difference is 13.63 GPixel/s in favor of the RX 560 XT (39.23 vs 25.60), and the texture rate difference is 47.7 GTexel/s in favor of the RX 560 XT (137.3 vs 89.60). These are not marginal gains; they are category-level wins.
The HD 7950's counterattack is memory bandwidth. Its 240.0 GB/s is 16.0 GB/s higher than the RX 560 XT's 224.0 GB/s, a 7% advantage. The HD 7950 also has a wider bus at 384-bit versus 256-bit, which can reduce latency in memory-bound tasks. In the Geekbench Metal test, the HD 7950 scores 33,951, which is actually higher than the RX 560 XT's OpenCL score of 31,387, though the tests are not directly comparable. The RX 560 XT's Vulkan score of 36,879 is the highest single benchmark number in the dataset for either card.
