AMD Radeon Pro W6800X Duo vs NVIDIA A10M Comparison

Head-to-Head Benchmarks

The sole direct benchmark comparison between the AMD Radeon Pro W6800X Duo and the NVIDIA A10M comes from Geekbench OpenCL, where the A10M delivers a decisive win. The NVIDIA card scores 135,230 against the AMD card's 124,927, a delta of -7.6% from the AMD's perspective. This means the A10M outperforms the W6800X Duo in this compute-oriented test by roughly eight percentage points. The result is notable because the W6800X Duo is a dual-GPU card with a significantly higher thermal envelope, yet the single-GPU A10M still manages to pull ahead in raw OpenCL throughput.

Looking at the broader benchmark landscape, the W6800X Duo's average benchmark score across all tests stands at 143,766, while the A10M's average is 135,230. That works out to a 6.3% advantage for the AMD card when considering all available benchmark data. However, this comparison is skewed by the fact that the W6800X Duo has three benchmark results (Geekbench Metal, OpenCL, and Vulkan), while the A10M has only one (OpenCL). The AMD card's Metal score of 180,749 and Vulkan score of 125,622 contribute heavily to its higher average, whereas the A10M's single OpenCL result of 135,230 stands alone. In the only apples-to-apples test, the NVIDIA part wins.

The rivalry data provides additional context. The W6800X Duo sits at the 98th percentile among all GPUs, while the A10M is at the 97th percentile. In terms of nearest competitors, the W6800X Duo trails the NVIDIA A10G (average score 151,963) by 5.4%, but leads the A10M itself by 6.3%, the RTX 4000 Ada Generation by 6.3%, and the AMD Radeon RX 9070 GRE by 7%. The A10M, meanwhile, is essentially tied with the RTX 4000 Ada Generation (135,218, delta 0%), leads the RX 9070 GRE (134,417) by 0.6%, leads the AMD Radeon PRO W6800 (133,588) by 1.2%, and beats the GeForce RTX 3090 Ti (131,911) by 2.5%. These numbers show that both cards occupy a similar performance tier, with the W6800X Duo having a slight edge in aggregate but the A10M winning the one direct head-to-head.

The wins tally confirms the split: the A10M claims 1 win, the W6800X Duo claims 0 in direct comparisons. Yet the average benchmark score tells a different story, favoring the AMD card. This is a classic case where the choice of benchmark dramatically influences the outcome. OpenCL is a cross-platform compute standard, and NVIDIA's Ampere architecture is known for strong compute throughput in such workloads. The W6800X Duo's higher average is driven by its exceptional Metal performance, which is irrelevant to most server or workstation scenarios outside the Apple ecosystem.

Architecture Differences

The two cards are built on fundamentally different architectures. The AMD Radeon Pro W6800X Duo uses the Navi 21 chip based on RDNA 2.0, fabricated on a 7 nm process at TSMC. The NVIDIA A10M uses the GA102 chip based on Ampere, fabricated on an 8 nm process at Samsung. This process difference is significant: the AMD chip packs 26,800 million transistors into a 520 mm² die, yielding a transistor density of 51.5 million per square millimeter. The NVIDIA chip has more transistors overall — 28,300 million — but spreads them across a larger 628 mm² die, resulting in a lower density of 45.1 million per square millimeter. The AMD process advantage is clear, but the NVIDIA chip compensates with a larger physical footprint and more total transistors.

The compute architectures diverge sharply. The W6800X Duo has 3,840 shading units, 240 texture mapping units, and 96 raster operation pipelines. It also includes 60 ray tracing cores. The A10M has 7,168 shading units — nearly double — but only 224 TMUs and 80 ROPs. It includes 56 ray tracing cores and, crucially, 224 tensor cores, which the AMD card lacks entirely. This tensor core presence is a major architectural differentiator, enabling the A10M to accelerate AI and deep learning workloads that the W6800X Duo cannot handle with dedicated hardware.

Clock speeds and compute throughput tell the performance story. The W6800X Duo runs at a base clock of 1800 MHz and boosts to 1967 MHz, while the A10M operates at a much lower base of 975 MHz but boosts to 1635 MHz. Despite the higher clocks, the AMD card delivers only 15.11 TFLOPS of FP32 performance, while the A10M achieves 23.44 TFLOPS. The NVIDIA card's greater shading unit count more than compensates for its lower clock speeds. In FP16, the AMD card delivers 30.21 TFLOPS (at a 2:1 ratio), while the A10M delivers 23.44 TFLOPS (at a 1:1 ratio). The AMD card's FP16 advantage is notable, but the A10M's tensor cores provide a different kind of compute acceleration for AI workloads.

Memory architectures also differ. The W6800X Duo uses 32 GB of GDDR6 on a 256-bit bus, achieving 512.0 GB/s of bandwidth. The A10M uses 20 GB of GDDR6 on a 320-bit bus, achieving 500.2 GB/s. The AMD card has more capacity and slightly higher bandwidth, but the NVIDIA card has a wider bus. Pixel fill rates favor AMD at 188.8 GPixel/s versus 130.8 GPixel/s, and texture fill rates also favor AMD at 472.1 GTexel/s versus 366.2 GTexel/s. These differences reflect the AMD card's higher clock speeds and different resource allocation.

Specification Differences

The two cards differ across nearly every major specification category. The W6800X Duo uses an AMD Navi 21 chip on RDNA 2.0 architecture, while the A10M uses an NVIDIA GA102 chip on Ampere architecture. Manufacturing processes differ: TSMC 7 nm for AMD versus Samsung 8 nm for NVIDIA. Transistor counts are close but not equal — 26,800 million for AMD versus 28,300 million for NVIDIA — and die sizes differ accordingly: 520 mm² versus 628 mm².

Memory configurations diverge significantly. The AMD card has 32 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth. The NVIDIA card has 20 GB of GDDR6 on a 320-bit bus with 500.2 GB/s bandwidth. Memory clocks also differ: the AMD card runs at 2000 MHz (16 Gbps effective), while the NVIDIA card runs at 1563 MHz (12.5 Gbps effective).

Compute resources show a stark contrast. The AMD card has 3,840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores, with no tensor cores. The NVIDIA card has 7,168 shading units, 224 TMUs, 80 ROPs, 56 ray tracing cores, and 224 tensor cores. The AMD card has higher pixel rate (188.8 GPixel/s versus 130.8 GPixel/s) and texture rate (472.1 GTexel/s versus 366.2 GTexel/s), but the NVIDIA card has higher FP32 throughput (23.44 TFLOPS versus 15.11 TFLOPS). FP16 performance favors AMD at 30.21 TFLOPS versus 23.44 TFLOPS.

Power and physical specifications are dramatically different. The AMD card has a TDP of 400 W and requires an 800 W suggested PSU, while the NVIDIA card has a TDP of 150 W and requires a 450 W suggested PSU. The AMD card is a quad-slot design, while the NVIDIA card is single-slot. The AMD card uses an Apple MPX bus interface, while the NVIDIA card uses PCIe 4.0 x16. The AMD card has display outputs (1x HDMI 2.1, 4x Thunderbolt), while the NVIDIA card has no display outputs. The AMD card has a launch MSRP of 4,999 USD; the NVIDIA card has no launch MSRP listed. Dimensions are similar in length (both 267 mm), but heights differ: 120 mm for AMD versus 112 mm for NVIDIA.

The Verdict

The data presents a clear but nuanced picture. For users who need maximum compute performance in a single OpenCL workload, the NVIDIA A10M is the superior choice, delivering 7.6% higher scores in the direct head-to-head. Its 150 W TDP and single-slot form factor make it dramatically more power-efficient and physically compact, while its 224 tensor cores provide dedicated AI acceleration that the AMD card cannot match. The A10M is also the only one of the two with a PCIe 4.0 x16 interface, making it compatible with standard server and workstation platforms.

For users operating within the Apple ecosystem, the AMD Radeon Pro W6800X Duo is the only viable option, as it uses the Apple MPX bus interface and includes display outputs. Its 32 GB of memory exceeds the A10M's 20 GB, which is advantageous for large datasets. The W6800X Duo also delivers higher FP16 performance (30.21 TFLOPS versus 23.44 TFLOPS) and superior pixel and texture fill rates, which benefit graphics-intensive workloads. Its average benchmark score of 143,766 is 6.3% higher than the A10M's, driven by strong Metal and Vulkan results.

The verdict hinges on use case. Users prioritizing raw compute in a standard server environment should choose the A10M, which wins the direct benchmark, offers tensor core acceleration, and consumes 250 W less power. Users requiring Apple Mac Pro compatibility, larger memory capacity, or higher fill rates should choose the W6800X Duo, despite its higher power draw and quad-slot footprint. The A10M's 97th percentile ranking and near-identical performance to the RTX 4000 Ada Generation suggest it is a well-balanced compute card, while the W6800X Duo's 98th percentile ranking and 7% lead over the RX 9070 GRE show its strength in diverse workloads. Neither card is universally better; the correct choice depends entirely on the target platform and workload mix.
