AMD Radeon PRO W7700 vs NVIDIA Quadro RTX 6000 Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear, though not uniform, picture of performance between these two workstation GPUs. Across the two tests recorded, the AMD Radeon PRO W7700 secures victory in both, but the magnitude of its wins varies wildly depending on the workload.

The most decisive result comes from the Geekbench OpenCL test. Here, the AMD card scores 108,245 points against the Quadro RTX 6000's 74,179 points. This represents a 45.9% advantage for the Radeon PRO W7700. That is a substantial margin that would translate into a major real-world difference for compute-heavy tasks leveraging OpenCL. The data clearly indicates that in this specific workload, the newer AMD architecture holds a commanding lead over the older NVIDIA Turing design.

However, the story changes considerably when examining the Vulkan benchmark results. In this test, the scores are nearly identical. The AMD Radeon PRO W7700 achieves 129,706 points, narrowly edging out the NVIDIA Quadro RTX 6000's 129,564 points. The delta here is a razor-thin 0.1%. This effectively means that for Vulkan-based applications, both cards deliver statistically equivalent performance. This near-tie is notable because it shows that despite the significant architectural differences and generational gap, the older NVIDIA card can still match the newer AMD competitor in specific API scenarios.

Looking at the broader context, the AMD card's average benchmark score of 118,976 places it in the 95th percentile of all GPUs. Its nearest rivals, based on average score, include the NVIDIA GB10 (117,393, 1.3% slower) and the NVIDIA RTX 4000 SFF Ada Generation (117,088, 1.6% slower). In contrast, the NVIDIA Quadro RTX 6000's average score of 101,872 puts it in the 94th percentile, with its closest competitor being the AMD Radeon Pro Vega II Duo (106,750, which is 4.6% faster). This suggests that while the RTX 6000 remains a high-performing card in the overall distribution, its average performance is more than 14% behind the Radeon PRO W7700's average.

The Verdict

The performance data leads to a straightforward recommendation for most users. The AMD Radeon PRO W7700 is the superior choice for workloads that are heavily dependent on OpenCL compute performance. Its 45.9% lead in that specific benchmark is a decisive factor. For users running simulations, rendering tasks, or data processing that utilizes OpenCL, the performance uplift is substantial and will directly translate to faster job completion times.

For workloads that rely on Vulkan, the choice is less clear-cut. With a 0.1% difference, neither card has a meaningful performance advantage. In this scenario, other factors—such as memory capacity, software ecosystem, or platform compatibility—would be the primary differentiators in a purchasing decision.

The NVIDIA Quadro RTX 6000, despite its age, remains a competent card, sitting in the 94th percentile of all GPUs. However, its average benchmark score of 101,872 is significantly lower than the AMD card's 118,976. The data suggests that the RTX 6000 is best suited for legacy application compatibility or specific NVIDIA software stacks where its feature set is required, rather than for raw performance leadership.

Architecture Differences

The architectural disparity between these two GPUs is profound, reflecting a nearly five-year gap in design philosophy. The AMD Radeon PRO W7700 is built on the RDNA 3.0 architecture, using the Navi 32 chip, and is fabricated on a 5 nm process at TSMC. This advanced node allows AMD to pack 28,100 million transistors onto a 346 mm² die, yielding a transistor density of 81.2M / mm². The chip's codename is "Wheat Nas," and it belongs to the Radeon Pro Navi (Navi III Series) generation.

In stark contrast, the NVIDIA Quadro RTX 6000 is based on the older Turing architecture, using the TU102 chip, and is fabricated on a 12 nm process at TSMC. This larger, older process results in 18,600 million transistors spread across a massive 754 mm² die, giving a transistor density of just 24.7M / mm². The generational leap in manufacturing is evident: the AMD chip is denser, more power-efficient per transistor, and significantly smaller despite having more transistors.

The compute resources also differ fundamentally. The AMD card features 3,072 shading units, 192 texture mapping units (TMUs), and 96 render output units (ROPs). It also has 48 dedicated ray tracing cores. NVIDIA's Turing architecture, however, introduced both RT cores and Tensor cores. The Quadro RTX 6000 is equipped with 72 RT cores and 576 Tensor cores, alongside 4,608 shading units and 288 TMUs. While the NVIDIA card has more raw shaders and TMUs, the AMD card's higher clock speeds allow it to achieve a higher FP32 throughput of 31.95 TFLOPS versus NVIDIA's 16.31 TFLOPS. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The specification sheets reveal where each card has its strengths. The most obvious difference is in memory. The NVIDIA Quadro RTX 6000 offers 24 GB of GDDR6 memory on a 384-bit bus, providing a bandwidth of 672.0 GB/s. The AMD Radeon PRO W7700 provides 16 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 576.0 GB/s. This means the NVIDIA card holds a clear advantage in both capacity and bandwidth, which is critical for very large datasets or high-resolution texture workloads.

Clock speeds are where AMD takes the lead. The Radeon PRO W7700 has a base clock of 1900 MHz and a boost clock of 2600 MHz, significantly higher than the Quadro RTX 6000's 1440 MHz base and 1770 MHz boost. The AMD card's memory also runs at a faster effective speed of 18 Gbps, compared to NVIDIA's 14 Gbps. This higher clock speed is the primary driver behind the AMD card's superior pixel rate (249.6 GPixel/s vs. 169.9 GPixel/s) and texture rate (499.2 GTexel/s vs. 509.8 GTexel/s, which is a rare NVIDIA win).

Power and connectivity also differ. The AMD card has a lower TDP of 190 W with a single 8-pin power connector and a suggested PSU of 450 W. The NVIDIA card draws more power, with a 260 W TDP, requiring a 6-pin and an 8-pin connector and a 600 W suggested PSU. The bus interface also differs: AMD uses PCIe 4.0 x16, while NVIDIA uses the older PCIe 3.0 x16. For display outputs, the AMD card offers 4x DisplayPort 2.1, whereas the NVIDIA card provides 4x DisplayPort 1.4a and 1x USB Type-C. Physically, the AMD card is shorter at 241 mm (9.5 inches) compared to NVIDIA's 267 mm (10.5 inches), but both are dual-slot designs with the same height of 111 mm.
