AMD Radeon PRO W6600 vs NVIDIA A10M Comparison

Where Each One Wins

The benchmark data splits these two workstation cards into very different performance tiers. The NVIDIA A10M dominates the only shared workload recorded in the database, Geekbench OpenCL, posting a score of 135,230 against the AMD Radeon PRO W6600's 73,514. That is an 84% advantage, a margin that places the A10M in the 96th percentile of all GPUs, while the W6600 sits in the 92nd percentile. For compute-heavy OpenCL tasks, the A10M is the clear choice.

However, the Radeon PRO W6600 has its own arena where the A10M cannot compete: display output. The A10M has no display outputs at all, making it a pure compute accelerator for server environments. The W6600 ships with four DisplayPort 1.4a connectors, enabling multi-monitor workstation setups. The database also records additional API scores for the W6600, including Geekbench Metal at 94,042 and Geekbench Vulkan at 78,428, which are not available for the A10M, indicating broader API coverage in testing.

The A10M wins on raw compute, memory capacity, and memory bandwidth. The W6600 wins on practicality for desktop workstations, power efficiency, and API versatility. The choice depends entirely on whether the workload is headless compute or interactive graphics.

Architecture Differences

The A10M is built on NVIDIA's Ampere architecture using the GA102 chip, fabricated by Samsung on an 8 nm process. It packs 28,300 million transistors on a 628 mm² die, yielding a transistor density of 45.1 million per square millimeter. The W6600 uses AMD's RDNA 2.0 architecture with the Navi 23 chip, built by TSMC on a 7 nm process. It contains 11,060 million transistors on a 237 mm² die, with a density of 46.7 million per square millimeter. The W6600's smaller, denser chip is notable, but the A10M's massive die gives it far more raw resources.

The A10M's GA102 die is a high-end server part, while the Navi 23 is a midrange workstation chip. The transistor counts alone tell the story: 28.3 billion versus 11.06 billion. The A10M's Ampere architecture includes dedicated tensor cores, 224 of them, which the RDNA 2-based W6600 lacks entirely. Tensor cores accelerate AI and deep learning workloads, a feature absent from the AMD card. Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API compatibility is not a differentiator.

Clock speeds differ substantially. The W6600 runs at a 2,331 MHz base clock and 2,580 MHz boost, far higher than the A10M's 975 MHz base and 1,635 MHz boost. The AMD card compensates for fewer cores with higher clocks, while the A10M relies on sheer core count. Memory clocks also differ: the A10M uses 1,563 MHz (12.5 Gbps effective) GDDR6, while the W6600 uses 1,750 MHz (14 Gbps effective) GDDR6. The A10M's wider 320-bit bus dwarfs the W6600's 128-bit bus, explaining the massive bandwidth gap.

Head-to-Head Benchmarks

The single recorded head-to-head benchmark is Geekbench OpenCL, and the result is lopsided. The A10M scores 135,230, while the W6600 scores 73,514, giving the NVIDIA card an 84% lead. This is not a marginal victory; it is a dominant one. The A10M's nearest rivals in the database include the AMD Radeon PRO W6800 at 135,396 (0.1% higher), the AMD Radeon Pro W6800X Duo at 135,774 (0.4% higher), and the AMD Radeon PRO V620 at 136,472 (0.9% higher). The A10M is essentially tied with these cards, all clustered within 1% of each other. The W6600, by contrast, sits in a completely different tier. Its nearest rivals are the AMD Radeon Pro Vega 64X at 80,959 (1.3% higher), the NVIDIA GeForce RTX 5090 at 79,842 (2.7% higher), and the NVIDIA Tesla P100 PCIe 16 GB at 79,605 (3% higher). The W6600's average benchmark score across all tests is 81,995, while the A10M's is 135,230.

The A10M's 84% advantage in OpenCL is consistent with its hardware specifications. It has 7,168 shading units versus 1,792, 224 texture mapping units versus 112, and 80 ROPs versus 64. Its FP32 compute is 23.44 TFLOPS versus 9.247 TFLOPS for the W6600. Pixel rate favors the W6600 slightly at 165.1 GPixel/s versus 130.8 GPixel/s, but texture rate favors the A10M at 366.2 GTexel/s versus 289.0 GTexel/s. The A10M also has 56 RT cores versus 28 for the W6600, though neither card's ray tracing performance is captured in the recorded benchmarks.

Specification Differences

The two cards differ across nearly every major specification category. The A10M has a 20 GB GDDR6 memory pool on a 320-bit bus, delivering 500.2 GB/s of bandwidth. The W6600 has 8 GB GDDR6 on a 128-bit bus, with 224.0 GB/s. That is a 2.5x memory capacity advantage and a 2.2x bandwidth advantage for the NVIDIA card. The A10M's power connector is an 8-pin EPS, while the W6600 uses a single 6-pin. The suggested power supply is 450 W for the A10M and 300 W for the W6600. The A10M's TDP is 150 W, while the W6600 draws 100 W.

The A10M uses a PCIe 4.0 x16 interface, while the W6600 uses PCIe 4.0 x8. Both are single-slot cards. The A10M is 267 mm long (10.5 inches) and 112 mm tall (4.4 inches), while the W6600 is 241 mm long (9.5 inches) with no recorded height. The A10M has no display outputs, while the W6600 has four DisplayPort 1.4a connectors. The A10M's predecessor is Tesla Turing and its successor is Server Ada, while the W6600's predecessor is Radeon Pro Vega and it has no recorded successor. The W6600 has a recorded release date of June 7, 2021, while the A10M has none. The W6600's launch MSRP is 649 USD. Both cards are end-of-life.

The A10M's FP16 performance matches its FP32 at 23.44 TFLOPS (1:1 ratio), while the W6600's FP16 is 18.49 TFLOPS (2:1 ratio). This means the A10M handles FP16 at the same rate as FP32, while the W6600 doubles its rate, a characteristic of RDNA 2's packed math. However, the A10M's absolute FP16 output is still higher.
