AMD Radeon HD 7970M vs AMD Radeon PRO W7500 Comparison

The Verdict

Based strictly on the benchmark data available, the AMD Radeon PRO W7500 is the clear performance winner. In the single head-to-head benchmark recorded (Geekbench OpenCL), the PRO W7500 scores 58,213 compared to the HD 7970M’s 17,019, a difference of 70.8% in favor of the newer card. The HD 7970M wins zero benchmarks in this comparison.

The data suggests two very different products for two very different users. The Radeon PRO W7500 is an active, professional workstation card built on a modern architecture, with a launch MSRP of 429 USD. It offers a massive compute advantage, more memory, and support for modern APIs like DirectX 12 Ultimate and Vulkan 1.4. The Radeon HD 7970M is an end-of-life mobile module from 2012, designed for laptops (MXM form factor). Its only benchmark score places it in the 60th percentile of all GPUs, slightly behind the NVIDIA GeForce GTX 690 (-0.1%) and the AMD Radeon RX 7600 XT (-0.4%), while slightly ahead of the NVIDIA Tesla M4 (0.5%).

If the data reflects your workload—especially OpenCL compute—the PRO W7500 is the only rational choice. The HD 7970M should only be considered in legacy systems where its specific MXM-B (3.0) interface is required, as it cannot be installed in a standard desktop PCIe slot. The PRO W7500’s 8 GB of GDDR6 memory versus the HD 7970M’s 2 GB of GDDR5 also creates a practical separation for modern workloads. However, note the PRO W7500’s percentile ranking (59th) is actually slightly lower than the HD 7970M’s (60th), driven by its average score across all tests (16,415) being dragged down by low DirectX 9 and DirectX 12 Passmark scores (200 and 46 respectively). This indicates the PRO W7500 is a specialized compute card, not a universal gaming or legacy API beast.

Architecture Differences

The two GPUs are separated by more than a decade of architectural evolution. The HD 7970M uses the “Wimbledon” chip based on GCN 1.0 architecture, fabricated on a 28 nm process at TSMC with 2,800 million transistors on a 212 mm² die (transistor density of 13.2M / mm²). In contrast, the PRO W7500 uses the “Navi 33” chip built on RDNA 3.0 (codename “Hotpink Bonefish”), fabricated on a 6 nm process at TSMC with 13,300 million transistors on a slightly smaller 204 mm² die. This yields a dramatically higher transistor density of 65.2M / mm²—nearly 5 times denser.

The PRO W7500 introduces hardware features the HD 7970M simply lacks. The RDNA 3.0 card has 28 dedicated ray tracing cores, while the GCN 1.0 chip has none. The PRO W7500 also has more shading units (1,792 vs 1,280), more texture mapping units (112 vs 80), and double the render output units (64 vs 32). The PRO W7500 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the HD 7970M is limited to DirectX 12 (11_1) and Vulkan 1.2.170. Both cards support OpenGL 4.6, but the PRO W7500 also lists FP16 compute at 24.37 TFLOPS (2:1 ratio), while the HD 7970M has no FP16 data listed.

Memory technology differs fundamentally. The HD 7970M uses 2 GB of GDDR5 on a 256-bit bus, achieving 153.6 GB/s bandwidth. The PRO W7500 uses 8 GB of GDDR6 on a narrower 128-bit bus, yet achieves higher bandwidth at 256.0 GB/s due to faster memory clocks (2000 MHz / 16 Gbps effective vs 1200 MHz / 4.8 Gbps effective). The PRO W7500 also has significantly higher pixel and texture rates: 108.8 GPixel/s vs 27.20 GPixel/s, and 190.4 GTexel/s vs 68.00 GTexel/s respectively.

Head-to-Head Benchmarks

The only direct comparison available is Geekbench OpenCL, and the result is decisive. The AMD Radeon PRO W7500 scores 58,213, while the AMD Radeon HD 7970M scores 17,019. The PRO W7500 leads by 70.8% (the negative deltaPct of -70.8 indicates the HD 7970M is that much slower). This is a 3.4x raw score improvement, which aligns with the theoretical compute difference: the PRO W7500 delivers 12.19 TFLOPS FP32 versus the HD 7970M’s 2.176 TFLOPS, a 5.6x gap in raw shader throughput. The benchmark gap is smaller than the theoretical peak, suggesting real-world OpenCL workloads are not purely shader-bound, but the direction is unambiguous.

For context, the HD 7970M’s OpenCL score of 17,019 places it within 0.1% of the NVIDIA GeForce GTX 690 (17,037) and 0.4% of the AMD Radeon RX 7600 XT (17,083). It is 0.5% faster than the NVIDIA Tesla M4 (16,932) but 1.1% slower than the NVIDIA GeForce RTX 3070 (17,208). The PRO W7500’s average benchmark score of 16,415 (across all tests) is actually lower than its Geekbench OpenCL score due to weak Passmark results, but its nearest rivals tell a different story: it matches the NVIDIA RTX PRO 6000 Blackwell (16,408, 0% delta), is 0.3% faster than the AMD Radeon RX 5700 XT (16,361), 0.4% faster than the AMD Radeon Pro 5600M (16,351), and 0.5% slower than the NVIDIA GeForce RTX 5090 D V2 (16,504).

Where Each One Wins

AMD Radeon PRO W7500 wins decisively in every measurable category. Its Geekbench OpenCL score is 70.8% higher, its FP32 compute is 5.6x higher (12.19 vs 2.176 TFLOPS), and it has 4x the memory capacity (8 GB vs 2 GB). The PRO W7500 also has higher pixel rate (108.8 vs 27.20 GPixel/s), higher texture rate (190.4 vs 68.00 GTexel/s), and more shading units (1,792 vs 1,280). It supports modern features like ray tracing, DirectX 12 Ultimate, and Vulkan 1.4. Its 70 W TDP is also lower than the HD 7970M’s 100 W, making it more efficient. For any modern compute, professional visualization, or API-modern workload, the data points entirely to the PRO W7500.

AMD Radeon HD 7970M wins only in legacy compatibility and form-factor specificity. Its MXM-B (3.0) interface makes it the only option for certain older laptops that require this module type. Its 256-bit memory bus is wider than the PRO W7500’s 128-bit bus, though this does not translate to higher bandwidth (153.6 vs 256.0 GB/s). The HD 7970M’s percentile rank (60th) is marginally higher than the PRO W7500’s (59th), driven by the PRO W7500’s low Passmark DirectX 9 (200) and DirectX 12 (46) scores. However, the HD 7970M has no ray tracing cores, no FP16 data, and is end-of-life. Its single benchmark score places it near the NVIDIA GTX 690 and RX 7600 XT, but that is a 2012-level performance tier. For any user with a choice between the two, the PRO W7500 is the only card with meaningful performance headroom.
