AMD FirePro W7000 vs AMD Radeon HD 8970M Comparison

# AMD Radeon HD 8970M vs AMD FirePro W7000

The AMD Radeon HD 8970M and AMD FirePro W7000 share the same GCN 1.0 architecture, 28 nm TSMC process, 2,800 million transistors, and a 212 mm² die size, yet they target different use cases. The HD 8970M is a mobile part built on the Neptune chip, while the W7000 is a single-slot workstation card using Pitcairn. Benchmark results show the HD 8970M leading in OpenCL compute with a 19.3% advantage, but the W7000 counters with a Vulkan score that the mobile part cannot match. This split in strengths makes the choice dependent on workload priorities rather than a simple performance hierarchy.

Where Each One Wins

The data points to a clear division of labor. In the Geekbench OpenCL test, the AMD Radeon HD 8970M scores 21,237, which is 19.3% ahead of the FirePro W7000’s 17,808. This is the only head-to-head benchmark listed, and the HD 8970M wins it decisively. The mobile card’s average benchmark score across all tests is 21,237, placing it at the 66th percentile of all GPUs. Its nearest rivals include the NVIDIA RTX A4000 Mobile at 21,379 (0.7% faster) and the AMD Radeon RX Vega M GL at 21,153 (0.4% slower), showing that the HD 8970M sits in a competitive mid-range compute tier.

The FirePro W7000, by contrast, posts an average benchmark score of 19,905 across its two recorded tests, landing at the 65th percentile. Its OpenCL result of 17,808 is its weaker showing; its Vulkan score of 22,001 is significantly higher. That Vulkan figure is not part of the head-to-head comparison, but it demonstrates that the W7000 has a strength the HD 8970M cannot claim — the mobile part has no Vulkan benchmark entry at all. The W7000’s nearest rivals include the NVIDIA Tesla K40m at 19,885 (0.1% behind) and the AMD Radeon RX 6650 XT at 19,765 (0.7% behind), indicating that its average performance clusters tightly with older professional and mid-range consumer parts.

In practical terms, the HD 8970M wins for raw OpenCL compute throughput, while the W7000 wins for Vulkan-capable workloads. The W7000 also offers fixed display outputs (4x DisplayPort 1.2) and a desktop form factor, whereas the HD 8970M’s outputs are portable-device dependent. For users needing a stationary workstation GPU with multiple display connections, the W7000 is the only one of the two that provides that out of the box.

Architecture Differences

Both GPUs are built on GCN 1.0, but they use different chips. The HD 8970M uses Neptune, while the W7000 uses Pitcairn. Despite the different chip names, the core specifications are identical: 1,280 shading units, 80 texture mapping units, and 32 raster operation units. Both have 4 GB of GDDR5 memory on a 256-bit bus, yielding 153.6 GB/s of bandwidth. The memory clock is also the same at 1200 MHz (4.8 Gbps effective). Transistor count and die size match exactly at 2,800 million and 212 mm², respectively, with a transistor density of 13.2M per mm².

The differences emerge in clock speeds and derived rates. The HD 8970M has a base clock of 850 MHz and a boost clock of 900 MHz, producing a pixel rate of 28.80 GPixel/s, a texture rate of 72.00 GTexel/s, and FP32 performance of 2.304 TFLOPS. The W7000 lists no base or boost clocks in the data, but its pixel rate is 30.40 GPixel/s, texture rate is 76.00 GTexel/s, and FP32 is 2.432 TFLOPS. This means the W7000 operates at a higher effective clock speed, delivering roughly 5.6% more pixel throughput, 5.6% more texture throughput, and 5.6% more FP32 compute than the HD 8970M. Yet in the OpenCL benchmark, the HD 8970M still wins by a wide margin — a result that points to thermal or driver-related advantages in the mobile part’s favor.

Power and physical design differ substantially. The HD 8970M is rated at 100 W TDP and uses an MXM module form factor, making it suitable for laptops. The W7000 draws 150 W, requires a single 6-pin power connector, and needs a 450 W suggested power supply. It is a single-slot card measuring 242 mm (9.5 inches) in length and 111 mm (4.4 inches) in height. Both support PCIe 3.0 x16, DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The W7000’s release date is 2012-06-12, while the HD 8970M launched nearly a year later on 2013-05-13. Both are end-of-life products.

The Verdict

The data supports a straightforward recommendation based on workload. For OpenCL compute, the AMD Radeon HD 8970M is the clear choice — its 21,237 score is 19.3% higher than the W7000’s 17,808, and it achieves this at a lower 100 W TDP. The mobile card also has a higher percentile ranking (66th vs 65th) and a better average benchmark score (21,237 vs 19,905). Anyone prioritizing OpenCL performance in a portable form factor should pick the HD 8970M.

For Vulkan workloads, the AMD FirePro W7000 is the only option with a recorded score: 22,001. The HD 8970M has no Vulkan benchmark entry, so the W7000 wins that category by default. The W7000 also provides four DisplayPort 1.2 outputs, a fixed desktop form factor, and a higher theoretical peak in FP32 (2.432 TFLOPS vs 2.304 TFLOPS), pixel rate, and texture rate. If the task involves Vulkan rendering or requires multiple display outputs on a workstation, the W7000 is the appropriate selection.

Neither card is a universal winner. The HD 8970M leads in the only direct comparison, but the W7000’s Vulkan capability and higher raw throughput rates give it distinct advantages in specific scenarios. The choice hinges entirely on whether the workload is OpenCL-centric (choose HD 8970M) or Vulkan/display-centric (choose W7000).

Head-to-Head Benchmarks

The only head-to-head benchmark in the data is Geekbench OpenCL, and it is a decisive win for the AMD Radeon HD 8970M. The HD 8970M scores 21,237 against the FirePro W7000’s 17,808, a delta of 19.3%. This margin is substantial in GPU terms — the HD 8970M outperforms the W7000 by nearly one-fifth in raw OpenCL compute. To put that in context, the HD 8970M’s nearest rival, the NVIDIA RTX A4000 Mobile, is only 0.7% faster, and the AMD Radeon RX Vega M GL is 0.4% slower. The W7000’s nearest rival, the NVIDIA Tesla K40m, is just 0.1% behind it. So the gap between the two cards in OpenCL is far larger than the gaps to their respective competitors, making the HD 8970M’s advantage especially pronounced.

The W7000’s best result comes from its Vulkan score of 22,001, which is higher than the HD 8970M’s OpenCL score of 21,237. However, since the HD 8970M has no Vulkan benchmark entry, this comparison cannot be made directly. The W7000’s average benchmark score of 19,905 is dragged down by its weaker OpenCL result; without the Vulkan score, its average would be lower. The HD 8970M’s average equals its OpenCL score because that is its only listed benchmark.

In theoretical performance, the W7000 leads across the board. Its pixel rate of 30.40 GPixel/s exceeds the HD 8970M’s 28.80 GPixel/s by 5.6%. Its texture rate of 76.00 GTexel/s beats 72.00 GTexel/s by the same percentage. FP32 throughput follows the same pattern: 2.432 TFLOPS vs 2.304 TFLOPS, again a 5.6% advantage. These rates suggest the W7000 should compute faster in peak throughput, yet the OpenCL benchmark shows the opposite. The discrepancy likely stems from real-world factors such as driver optimization, thermal throttling, or memory access patterns — but the data only records the scores, not the causes.

Specification Differences

The two cards differ in several key fields. The HD 8970M uses the Neptune chip, while the W7000 uses Pitcairn. The HD 8970M has a base clock of 850 MHz and a boost clock of 900 MHz; the W7000 lists no base or boost clocks. The HD 8970M’s pixel rate is 28.80 GPixel/s versus the W7000’s 30.40 GPixel/s. Texture rates are 72.00 GTexel/s and 76.00 GTexel/s, respectively. FP32 performance is 2.304 TFLOPS for the HD 8970M and 2.432 TFLOPS for the W7000.

TDP is a major differentiator: 100 W for the HD 8970M, 150 W for the W7000. The HD 8970M uses an MXM module slot width, while the W7000 is single-slot. The W7000 has a 1x 6-pin power connector and a 450 W suggested PSU; the HD 8970M lists no power connectors or suggested PSU. Display outputs are portable-device dependent for the HD 8970M, but the W7000 offers 4x DisplayPort 1.2. The W7000 has physical dimensions of 242 mm (9.5 inches) in length and 111 mm (4.4 inches) in height; the HD 8970M has no listed dimensions.

Release dates differ: the W7000 launched on 2012-06-12, and the HD 8970M on 2013-05-13. The W7000 has a launch MSRP of 899 USD; the HD 8970M has none listed. The W7000’s predecessor is FirePro Terascale and its successor is Radeon Pro Polaris. The HD 8970M’s predecessor is London and its successor is Gem System. Both support PCIe 3.0 x16, DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, and both are end-of-life products.
