AMD Radeon Pro W6800X Duo vs NVIDIA GB10 Comparison

Head-to-Head Benchmarks

The AMD Radeon Pro W6800X Duo wins both head-to-head benchmark comparisons against the NVIDIA GB10, but the margins are far from overwhelming. In Geekbench OpenCL, the AMD card scores 124,335 against the NVIDIA's 120,137, a 3.5% lead. The gap widens in Geekbench Vulkan, where the AMD posts 125,622 versus 114,648, translating to a 9.6% advantage. While the AMD card claims victory in both tests, the magnitude of these wins is modest given the architectural gulf between the two products.

Looking at average benchmark scores across all tests, the AMD Radeon Pro W6800X Duo averages 135,774, placing it at the 96th percentile of all GPUs. The NVIDIA GB10 averages 117,393, sitting at the 95th percentile. The 18,381-point gap in average scores represents a roughly 15.7% overall advantage for the AMD card, yet both occupy essentially the same performance tier when measured against the broader GPU landscape.

The AMD's nearest rivals include the AMD Radeon PRO W6800 (135,396, +0.3%), NVIDIA A10M (135,230, +0.4%), NVIDIA RTX 4000 Ada Generation (135,218, +0.4%), and AMD Radeon PRO V620 (136,472, -0.5%). These deltas show the W6800X Duo is squarely within a 1% band of its closest competitors, meaning its 96th percentile standing is not a dominant position but rather a clustered one. For the NVIDIA GB10, the nearest rivals are the NVIDIA RTX 4000 SFF Ada Generation (117,088, +0.3%), AMD Radeon PRO W7700 (118,976, -1.3%), NVIDIA Tesla V100 SXM2 16 GB (114,395, +2.6%), and NVIDIA RTX A5500 Mobile (113,944, +3%). The GB10 leads its closest rival by just 0.3% and trails the W7700 by 1.3%, indicating a similarly tight grouping.

The Geekbench OpenCL result is particularly telling. The AMD's 3.5% lead in OpenCL narrows the practical difference between the two to a margin that could be lost in driver-level variations or test methodology. The Vulkan result, however, shows a more decisive separation — the 9.6% delta suggests the AMD architecture has a more substantial advantage in that API's execution model. Neither benchmark shows the kind of blowout that the raw specification differences might suggest.

The Verdict

The data presents a clear but nuanced picture. The AMD Radeon Pro W6800X Duo is the benchmark winner, taking both head-to-head tests and posting a higher average score (135,774 vs 117,393). Its 96th percentile standing edges the NVIDIA's 95th, and it holds a 3.5% OpenCL lead and a 9.6% Vulkan lead. For anyone prioritizing raw benchmark performance in these specific tests, the AMD card is the data-backed choice.

However, the NVIDIA GB10 is not a poor performer — it sits within striking distance in OpenCL, and its 29.71 TFLOPS FP32 throughput versus the AMD's 15.11 TFLOPS suggests it has raw compute headroom that these particular benchmarks do not fully capture. The NVIDIA also offers substantially more memory (128 GB vs 32 GB) and a far lower power envelope (140 W vs 400 W), which are meaningful advantages for specific workloads.

The production status is a decisive factor. The AMD is end-of-life, while the NVIDIA is active production. The AMD's launch MSRP is 4,999 USD, and the NVIDIA's launch MSRP is 3,999 USD. The NVIDIA is also significantly newer, with an October 14, 2025 release date versus August 2, 2021 for the AMD. For a buyer choosing between these two today, the AMD's benchmark wins must be weighed against its discontinued status and the NVIDIA's active lifecycle.

Specification Differences

The two GPUs differ dramatically across nearly every specification. The AMD uses 32 GB of GDDR6 memory on a 256-bit bus with 512.0 GB/s bandwidth, while the NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth — the AMD has 87.4% more bandwidth, but the NVIDIA has 300% more capacity. Clock speeds favor the NVIDIA at the top end: its boost clock is 2418 MHz versus the AMD's 1967 MHz, though the AMD has a higher base clock at 1800 MHz versus 1665 MHz.

Shader resources heavily favor the NVIDIA: 6144 shading units versus 3840, 384 TMUs versus 240, and 384 tensor cores versus none on the AMD. However, the AMD counters with 96 ROPs versus 48, and 60 ray tracing cores versus 48. The NVIDIA's pixel rate is lower at 116.1 GPixel/s versus 188.8 GPixel/s, but its texture rate is far higher at 928.5 GTexel/s versus 472.1 GTexel/s. FP32 throughput is 29.71 TFLOPS for the NVIDIA versus 15.11 TFLOPS for the AMD, and FP16 is 29.71 TFLOPS (1:1) for the NVIDIA versus 30.21 TFLOPS (2:1) for the AMD.

Power and physical dimensions are starkly different. The AMD draws 400 W with an 800 W suggested PSU, while the NVIDIA draws 140 W with a 300 W suggested PSU. The AMD is a quad-slot card measuring 267 mm long and 120 mm high, while the NVIDIA is an IGP (integrated graphics processor) measuring 150 mm by 51 mm by 150 mm. The AMD uses an Apple MPX bus interface, while the NVIDIA uses PCIe 5.0 x16. Display outputs differ as well: the AMD has 1x HDMI 2.1 and 4x Thunderbolt, while the NVIDIA has only 1x HDMI.

Architecture Differences

The architectural split is fundamental. The AMD Radeon Pro W6800X Duo uses the Navi 21 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. It packs 26,800 million transistors into a 520 mm² die, yielding a transistor density of 51.5 million per mm². The NVIDIA GB10 uses the GB20B chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. Its die size is 382 mm², and its transistor count is listed as unknown.

The AMD belongs to the Radeon Pro Mac (Navi II Series) generation, while the NVIDIA belongs to the Server Blackwell (Bxx) generation. The NVIDIA's predecessor is Server Hopper and its successor is Server Rubin, placing it in an active lineage. The AMD has no listed predecessor or successor, consistent with its end-of-life status.

The memory architectures diverge significantly. The AMD pairs its 32 GB GDDR6 with a 256-bit bus, while the NVIDIA pairs its 128 GB LPDDR5X with a 256-bit bus. The NVIDIA's lack of DirectX, OpenGL, and Vulkan support in the API listings reinforces its server-oriented Blackwell architecture, whereas the AMD's full client API stack (including DirectX 12 Ultimate) reflects its workstation/consumer heritage. The NVIDIA's 384 tensor cores are its standout architectural feature, enabling AI workloads that the AMD cannot accelerate through dedicated tensor hardware.

Where Each One Wins

The AMD Radeon Pro W6800X Duo wins in every benchmark category measured. It leads in Geekbench OpenCL by 3.5%, in Geekbench Vulkan by 9.6%, and in average benchmark score by 15.7%. Its memory bandwidth advantage (512.0 GB/s vs 273.2 GB/s) and higher pixel rate (188.8 GPixel/s vs 116.1 GPixel/s) make it the stronger choice for graphics-heavy rendering workloads where pixel throughput and memory bandwidth dominate. Its 96 ROPs versus 48 on the NVIDIA also favor it in fill-rate-limited scenarios.

The NVIDIA GB10 wins in several non-benchmark categories that matter for specific use cases. Its 128 GB memory capacity is 300% larger than the AMD's 32 GB, making it the clear choice for large-model inference or data-intensive workloads that exceed 32 GB. Its 384 tensor cores provide dedicated AI acceleration hardware that the AMD entirely lacks. Its 29.71 TFLOPS FP32 throughput is nearly double the AMD's 15.11 TFLOPS, suggesting it may outperform in compute-bound tasks that scale with raw FLOPs rather than memory bandwidth.

The NVIDIA's 140 W power draw versus the AMD's 400 W makes it dramatically more power-efficient — it delivers 96.7% more FP32 throughput while consuming 65% less power. Its IGP form factor and PCIe 5.0 x16 interface make it suitable for dense server deployments, while the AMD's quad-slot Apple MPX design restricts it to specific Mac workstation configurations. The NVIDIA's active production status and 2025 release date mean it will receive ongoing support, while the AMD's end-of-life status means no further development. For AI workloads, memory-capacity-bound tasks, or power-constrained environments, the NVIDIA is the data-supported pick. For raw benchmark performance in OpenCL and Vulkan, the AMD holds the edge.
