AMD Radeon HD 7970 vs AMD Radeon Pro 5500 XT Comparison

Where Each One Wins

The benchmark record is unusually one-sided. Across the only shared test in the database, Geekbench OpenCL, the AMD Radeon Pro 5500 XT wins outright with a score of 41,772 against the HD 7970’s 34,541. That is a 20.9% advantage, a clear margin that places the newer card in a different performance class for compute workloads. The Pro 5500 XT also has additional data points in Geekbench Metal (54,779) and Geekbench Vulkan (39,601), while the HD 7970 has no recorded results in those APIs, meaning the older card cannot be directly compared there.

For a use-case split, the Pro 5500 XT is the pick for any OpenCL compute task, from rendering to physics simulations, where the 20.9% lead translates into shorter queue times and faster iteration. The HD 7970, despite its age, still holds a niche: it has a higher memory bus width (384 bit vs. 128 bit) and higher raw memory bandwidth (264.0 GB/s vs. 224.0 GB/s), which can matter in bandwidth-bound legacy workloads that do not scale with compute throughput. However, the database shows no benchmark where the HD 7970 wins. Its only recorded score, 34,541 in OpenCL, is lower across the board. If a workload depends on pixel fill rate, the Pro 5500 XT’s 56.22 GPixel/s versus 29.60 GPixel/s is a decisive factor, nearly doubling the HD 7970’s output. For texture-heavy scenes, the Pro 5500 XT’s 168.7 GTexel/s versus 118.4 GTexel/s is another win, a 42.5% advantage.

Architecture Differences

The architectural gulf between these two is vast, and it explains the benchmark gap. The Pro 5500 XT uses the Navi 14 chip on RDNA 1.0 architecture, built on a 7 nm TSMC process. The HD 7970 uses the Tahiti chip on GCN 1.0 architecture, built on a 28 nm TSMC process. That process shrink is not just about power; it enables a far denser design. The Pro 5500 XT packs 6,400 million transistors into a 158 mm² die, a transistor density of 40.5M per mm². The HD 7970 has 4,313 million transistors on a 352 mm² die, a density of 12.3M per mm². The newer card crams more than three times the transistors into less than half the die area.

The compute layouts differ fundamentally. The Pro 5500 XT uses 1,536 shading units, 96 texture mapping units, and 32 ROPs. The HD 7970 counters with 2,048 shading units, 128 TMUs, and 32 ROPs. So the older card has more raw shading units and TMUs, yet it loses in every measured metric. That is the RDNA versus GCN story: RDNA 1.0 extracts far more work per shader per clock. Clock speeds tell part of the tale. The Pro 5500 XT runs a base of 1187 MHz and a boost of 1757 MHz, while the HD 7970 has no base or boost clocks recorded in the database. The Pro 5500 XT’s FP32 output is 5.398 TFLOPS versus 3.789 TFLOPS for the HD 7970, a 42.5% lead despite having 512 fewer shading units. The HD 7970 has no recorded FP16 performance, while the Pro 5500 XT delivers 10.80 TFLOPS (2:1).

Memory architecture is another split. The Pro 5500 XT uses 8 GB of GDDR6 on a 128 bit bus, with memory clocked at 1750 MHz (14 Gbps effective) for 224.0 GB/s. The HD 7970 uses 3 GB of GDDR5 on a 384 bit bus, with memory at 1375 MHz (5.5 Gbps effective) for 264.0 GB/s. The HD 7970 has more bandwidth, but the Pro 5500 XT has more capacity and faster memory technology. API support also differs: the Pro 5500 XT supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the HD 7970 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The newer card supports a higher DirectX feature level and a newer Vulkan revision, which matters for modern games and compute frameworks.

The Verdict

The data points to one conclusion: the AMD Radeon Pro 5500 XT is the superior card for any modern workload. In the only head-to-head benchmark, it beats the HD 7970 by 20.9% in OpenCL. Its average benchmark score across all recorded tests is 45,384, placing it in the 84th percentile of all GPUs. The HD 7970’s average is 34,541, placing it in the 79th percentile. That is a 5 percentile-point gap, which is meaningful in a crowded field.

The Pro 5500 XT also has a much higher pixel rate (56.22 GPixel/s vs. 29.60 GPixel/s) and texture rate (168.7 GTexel/s vs. 118.4 GTexel/s), making it better for rasterization and texture-heavy rendering. It has more VRAM (8 GB vs. 3 GB), which is critical for modern datasets and high-resolution textures. It supports newer APIs, including Vulkan 1.4 and DirectX 12_1, while the HD 7970 is stuck at Vulkan 1.2.170 and DirectX 12_1. The HD 7970 has one advantage: raw memory bandwidth (264.0 GB/s vs. 224.0 GB/s) and a wider bus (384 bit vs. 128 bit), but that does not translate into a single benchmark win.

Pick the Pro 5500 XT if you need compute performance, modern API support, higher pixel and texture throughput, or more VRAM. Pick the HD 7970 only if you have a legacy workload that specifically benefits from its wider memory bus and higher bandwidth, and where its 3 GB VRAM is sufficient. Even then, the 20.9% compute deficit and the lack of any recorded win in the database make it a hard sell. The Pro 5500 XT is the safer, faster choice.

Head-to-Head Benchmarks

The only directly comparable measurement is Geekbench OpenCL, and it is a clean win for the Pro 5500 XT. The score is 41,772 versus 34,541, a delta of 20.9%. That is not a marginal edge; it is a full generation of compute improvement. To put it in context, the Pro 5500 XT’s nearest rivals in the database are the Intel Arc A730M (45,592, a 0.5% difference), the NVIDIA RTX 5090 Mobile (45,152, a 0.5% difference), the NVIDIA RTX 5880 Ada Generation (45,972, a 1.3% difference), and the NVIDIA GeForce RTX 4070 Ti (44,795, a 1.3% difference). The Pro 5500 XT is essentially trading blows with those much newer and more expensive parts, which shows how far ahead it is of the HD 7970.

The HD 7970’s nearest rivals are a different crowd: the NVIDIA T1000 8 GB (34,561, a 0.1% difference), the NVIDIA A2 (34,690, a 0.4% difference), the NVIDIA TITAN V (34,355, a 0.5% difference), and the NVIDIA RTX A1000 (34,207, a 1% difference). Those are low-power or older professional cards, and the HD 7970 sits right among them. That is the company it keeps in 2025. The Pro 5500 XT is a tier above.

Beyond the single shared test, the Pro 5500 XT has additional recorded scores that show its range: 54,779 in Geekbench Metal and 39,601 in Geekbench Vulkan. The HD 7970 has no entries for those APIs, so no direct comparison is possible, but the Vulkan score alone is 14.6% higher than the HD 7970’s best OpenCL result. That suggests the Pro 5500 XT would also win in Vulkan if the HD 7970 had a recorded score, given that Vulkan and OpenCL are both compute-oriented APIs and the architectural advantage is consistent.

The biggest win for the Pro 5500 XT is not just the score; it is the consistency. It wins the only test that matters, and it has a higher average, a higher percentile, and better specs in almost every category. The HD 7970’s only consolation is its memory bandwidth, but the data shows that bandwidth alone does not win benchmarks.

The specification sheet tells the same story as the benchmarks: the Pro 5500 XT is a modern replacement that wins where it matters.
