AMD Radeon AI PRO R9700 vs AMD Radeon HD 8970M Comparison

The AMD Radeon AI PRO R9700 and the AMD Radeon HD 8970M represent two distinct eras of GPU design, separated by over a decade of architectural evolution. The data shows a single head-to-head benchmark result, but the specification gap between these two cards is vast, making the performance delta predictable yet still striking.

Head-to-Head Benchmarks

The only common benchmark result in the data is Geekbench OpenCL, and the outcome is decisively one-sided. The Radeon AI PRO R9700 scores 118202 points, while the Radeon HD 8970M manages 21237 points. This translates to a 456.6% advantage for the newer card, meaning the R9700 delivers over five and a half times the raw compute throughput in this specific test.

The context from the nearest rivals reinforces this gap. The R9700’s average benchmark score of 23315 places it just 0.2% ahead of the AMD Radeon R9 M290X and the AMD Radeon RX 6600M, and 0.3% ahead of the AMD Radeon Pro Vega 16. These are all modern or near-modern parts, showing that the R9700 sits in a competitive performance tier. In contrast, the HD 8970M’s average score of 21237 puts it 0.4% ahead of the AMD Radeon RX Vega M GL but 0.7% behind the NVIDIA RTX A4000 Mobile and 1.8% behind the NVIDIA Quadro RTX 5000. The HD 8970M is not just slower than the R9700; it is also trailing many of its own contemporaries in the mobile and workstation space.

In the broader benchmark suite, the R9700 shows a spread of results. Its Passmark G3D score is 26979, and its Passmark GPU Compute score is 15300. It also posts 63550 in Geekbench Vulkan. The HD 8970M has no comparable scores in these tests within the provided data, so the Geekbench OpenCL result remains the sole direct comparison. The takeaway is clear: in the one measurable head-to-head, the R9700 is not merely faster—it is in a completely different performance class.

Architecture Differences

The architectural divide is fundamental. The R9700 uses the Navi 48 chip built on RDNA 4.0 architecture, manufactured on a 4 nm process at TSMC. The HD 8970M uses the Neptune chip with GCN 1.0 architecture, built on a 28 nm process, also at TSMC. This process shrink from 28 nm to 4 nm is a primary driver of the efficiency and performance differences.

The transistor counts tell a story of scale. The R9700 packs 53,900 million transistors into a 357 mm² die, achieving a density of 151.0M / mm². The HD 8970M has just 2,800 million transistors on a 212 mm² die, with a density of 13.2M / mm². That is roughly a 19-fold increase in transistor count and an 11-fold increase in density. The R9700’s die is larger, but the density increase shows how much more logic fits into the same physical space.

Core configurations are equally divergent. The R9700 features 4096 shading units, 256 texture mapping units, 128 ROPs, and 64 ray tracing cores. The HD 8970M has 1280 shading units, 80 TMUs, and 32 ROPs, with no ray tracing cores at all. The R9700 also carries dedicated hardware for ray tracing, a feature entirely absent from the older GCN part. Clock speeds differ markedly as well: the R9700 has a base clock of 1660 MHz and a boost clock of 2920 MHz, while the HD 8970M runs at 850 MHz base and 900 MHz boost.

Memory systems are a generation apart. The R9700 uses 32 GB of GDDR6 on a 256-bit bus, yielding 644.6 GB/s of bandwidth. The HD 8970M uses 4 GB of GDDR5 on the same 256-bit bus, but only achieves 153.6 GB/s. The R9700’s memory clock is 2518 MHz (effective 20.1 Gbps), while the HD 8970M’s is 1200 MHz (effective 4.8 Gbps). The newer card also supports PCIe 5.0 x16, whereas the HD 8970M is limited to PCIe 3.0 x16.

Other feature gaps include API support. The R9700 supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The HD 8970M supports DirectX 12 (11_1), Vulkan 1.2.170, and OpenGL 4.6. The R9700’s display outputs are listed as 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the HD 8970M’s outputs are marked as "Portable Device Dependent," reflecting its mobile MXM module design.

Where Each One Wins

The R9700 wins in every measurable category, but the nature of those wins points to different use cases. Its 47.84 TFLOPS of FP32 performance and matching 47.84 TFLOPS FP16 (1:1 ratio) make it suitable for compute-heavy workloads, including AI inference and scientific simulation. The 64 ray tracing cores and DirectX 12 Ultimate support position it for modern gaming and real-time rendering. The 32 GB memory buffer and 644.6 GB/s bandwidth are essential for large datasets, high-resolution textures, or multi-app workflows. Its production status is listed as "Active," meaning it is currently available for purchase.

The HD 8970M, with 2.304 TFLOPS FP32 and no FP16 data, is a legacy mobile part. Its 4 GB GDDR5 memory and 153.6 GB/s bandwidth are adequate for older 1080p gaming or basic compute tasks from its era, but they are severely limiting by modern standards. Its 100 W TDP is low, making it a potentially efficient choice for a legacy laptop, but its "End-of-life" production status means it is no longer manufactured. The HD 8970M’s only benchmark win is in the "Portable Device Dependent" display output category, which is a form factor advantage for mobile systems, not a performance metric.

The data shows the R9700 wins the only head-to-head test, has a higher percentile ranking (69 vs 66), higher average score (23315 vs 21237), and superior specifications across the board. The HD 8970M’s sole advantage is its lower power draw and mobile form factor, which are irrelevant for desktop or workstation use where the R9700 is designed to operate.

The Verdict

The choice between these two cards is not a choice at all for any modern workload. The R9700 is a current-generation workstation GPU with an "Active" production status, a launch MSRP of 1,299 USD, and performance that is 456.6% ahead in the sole head-to-head benchmark. It is designed for tasks like 3D rendering, AI development, and high-end compute, where its 32 GB memory, 47.84 TFLOPS FP32, and ray tracing support are directly applicable. Its nearest rivals are within 0.3% of its average score, confirming it is a competitive, modern part.

The HD 8970M is a 2013-era mobile GPU that is "End-of-life." Its 2.304 TFLOPS FP32 and 4 GB memory are insufficient for modern software. Its nearest rivals include the NVIDIA RTX A4000 Mobile and NVIDIA Quadro RTX 5000, which are themselves older mobile workstation parts, and it trails both in average score. The only scenario where the HD 8970M makes sense is in a legacy laptop where the MXM module form factor and 100 W TDP are mandatory constraints, and where the user’s software is from the same era as the hardware.

Strictly from the data, any user needing performance should pick the R9700. It is faster, more capable, and current. The HD 8970M is only relevant for niche, legacy mobile systems where the R9700 cannot physically fit or where power draw is an absolute limit. There is no performance-based argument for the HD 8970M.
