AMD Radeon PRO W6800 vs NVIDIA RTX 6000D Comparison

The benchmark data presents a clear hierarchy: the NVIDIA RTX 6000D is in a different performance class than the AMD Radeon PRO W6800. In the only shared benchmark test, Geekbench OpenCL, the RTX 6000D delivers a score of 388,405 against the W6800’s 121,808, a 218.9% advantage. The RTX 6000D sits in the 98th percentile of all GPUs, while the W6800 is in the 96th, but the average benchmark score gap is massive: 195,964 versus 135,396. This is not a close contest; it is a generational and architectural chasm.

Where Each One Wins

The NVIDIA RTX 6000D wins the only direct head-to-head benchmark available, and it wins by a landslide. In Geekbench OpenCL, the RTX 6000D scores 388,405, which is 218.9% higher than the W6800’s 121,808. This single result underscores that the RTX 6000D is the superior compute platform for OpenCL workloads, a common API for professional rendering and simulation.

The AMD Radeon PRO W6800 has no benchmark wins in the data. Its wins are not in raw performance but in operational characteristics. The W6800 is a dual-slot card with a 250 W TDP and a 600 W suggested PSU, whereas the RTX 6000D is also dual-slot but demands a 600 W TDP and a 1000 W suggested PSU. The W6800 uses two power connectors (1x 6-pin + 1x 8-pin) versus the RTX 6000D’s single 16-pin connector. The W6800’s physical footprint is smaller at 267 mm in length, 120 mm in height, and 50 mm in width, compared to the RTX 6000D’s 304 mm length, 137 mm height, and 40 mm width. For systems with power or space constraints, the W6800 is the more practical installation choice, though it sacrifices the RTX 6000D’s compute dominance.

The RTX 6000D also wins on longevity and support status. It is marked as "Active" production, while the W6800 is "End-of-life". The RTX 6000D’s release date is 2025-07-13, while the W6800’s is 2021-06-07. This makes the W6800 a legacy product, whereas the RTX 6000D is current-generation hardware.

Architecture Differences

The two cards are built on fundamentally different architectures. The RTX 6000D uses the GB202 chip based on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It integrates 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9M per mm². The W6800 uses the Navi 21 chip based on RDNA 2.0 architecture, also from TSMC, but on a 7 nm process. It has 26,800 million transistors on a 520 mm² die, with a density of 51.5M per mm². The RTX 6000D has over 3.4 times the transistor count on a die that is only 44% larger, illustrating the density advantage of the newer process node.

Memory architecture differs sharply. The RTX 6000D features 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The W6800 has 32 GB of GDDR6 on a 256-bit bus, with 512.0 GB/s of bandwidth. The RTX 6000D offers 2.6 times the memory capacity and 2.7 times the bandwidth. The RTX 6000D’s memory clock is 1560 MHz (25 Gbps effective), while the W6800’s is 2000 MHz (16 Gbps effective).

Head-to-Head Benchmarks

The only direct benchmark comparison is Geekbench OpenCL, and the result is lopsided. The NVIDIA RTX 6000D scores 388,405, while the AMD Radeon PRO W6800 scores 121,808. The delta is 218.9% in favor of the RTX 6000D. This means the RTX 6000D delivers more than triple the OpenCL performance of the W6800. For context, the RTX 6000D’s nearest rivals in aggregate average score are the NVIDIA A100 PCIe 80 GB, which it trails by 5.4%, and the NVIDIA Tesla V100S PCIe 32 GB, which it leads by 0.8%. The W6800’s nearest rivals are the NVIDIA A10M and RTX 4000 Ada Generation, which it essentially matches (0.1% delta), and the AMD Radeon Pro W6800X Duo, which it trails by 0.3%.

Beyond the shared test, the RTX 6000D’s raw specifications predict its dominance. Its FP32 throughput of 97.04 TFLOPS is 5.4 times the W6800’s 17.83 TFLOPS. Its texture rate of 1,516.3 GTexel/s is 2.7 times higher. Its pixel rate of 466.6 GPixel/s is 2.1 times higher. The RTX 6000D’s memory bandwidth of 1.40 TB/s eclipses the W6800’s 512.0 GB/s by a factor of 2.7. These aren’t marginal gains; they represent a full performance tier separation.

The W6800 does have a benchmark that the RTX 6000D doesn’t appear in: Geekbench Metal, where it scores 174,420, and Geekbench Vulkan, where it scores 109,961. However, the RTX 6000D’s OpenCL score of 388,405 is higher than any of the W6800’s individual benchmark scores, suggesting that in cross-API comparisons, the RTX 6000D’s compute advantage would likely persist.

The Verdict

From the data, the NVIDIA RTX 6000D is the superior workstation GPU for raw compute performance. It wins the only head-to-head benchmark by 218.9%, and its architectural specifications — 5 nm node, 92,200 million transistors, 84 GB GDDR7, 97.04 TFLOPS FP32 — position it as an extreme-performance part. The RTX 6000D’s average benchmark score of 195,964 is 44.8% above the W6800’s 135,396, and it ranks in the 98th percentile versus the W6800’s 96th. Anyone prioritizing OpenCL compute, large memory capacity, or future-proofing should choose the RTX 6000D. Its "Active" production status and 2025 release date mean it is current hardware, while the W6800 is end-of-life.

The AMD Radeon PRO W6800 is the choice only when operational constraints dominate. It draws 250 W versus 600 W, requires a 600 W PSU versus 1000 W, and is physically shorter (267 mm vs 304 mm) and narrower (50 mm vs 40 mm width). It offers six mini-DisplayPort 1.4a outputs versus four DisplayPort 2.1b, which could matter for multi-display setups. The W6800’s 32 GB of GDDR6 is ample for many professional workloads, and its 17.83 TFLOPS FP32 is not negligible. However, its 7 nm process, 26,800 million transistors, and RDNA 2.0 architecture are a generation behind. The W6800’s launch MSRP is 2,249 USD, while the RTX 6000D’s is 8,565 USD, but the performance delta of 218.9% in OpenCL justifies the price gap for compute-heavy tasks. For users with legacy software that favors AMD’s Metal or Vulkan paths, the W6800’s scores of 174,420 and 109,961 respectively are usable, but they are lower than the RTX 6000D’s OpenCL result. The verdict is clear: the RTX 6000D is for performance-critical workstations; the W6800 is for power-sensitive, space-constrained, or multi-display environments where its 250 W TDP and smaller footprint are decisive advantages.
