AMD Radeon RX 6700 XT vs NVIDIA RTX PRO 2000 Blackwell Comparison

The AMD Radeon RX 6700 XT and NVIDIA RTX PRO 2000 Blackwell are two very different products aimed at different users, yet their benchmark scores place them in a similar performance class. The data shows a 4-6 split in benchmark wins favoring the NVIDIA card, but the magnitude of those wins varies dramatically depending on the workload. The AMD card holds its own in traditional rasterization and compute, while the NVIDIA card dominates in modern API and compute-heavy tasks, making the choice highly dependent on your specific applications.

Head-to-Head Benchmarks

The single largest performance gap in the entire comparison is in the Geekbench OpenCL test, where the NVIDIA RTX PRO 2000 Blackwell scores 106,087 compared to the AMD Radeon RX 6700 XT's 44,152. This represents a massive 58.4% advantage for the NVIDIA card, a delta so large it suggests a fundamental difference in how the two architectures handle raw compute workloads. This is not a marginal edge; it is a decisive victory that will matter greatly for any professional application that leverages OpenCL for rendering, simulation, or data processing.

The NVIDIA card also wins in Geekbench Vulkan, scoring 113,865 against AMD's 93,500, a 17.9% lead. This is another significant win, indicating that the RTX PRO 2000 Blackwell is better optimized for modern, low-level graphics APIs. In the Passmark G2D test, the NVIDIA card again takes the lead with a score of 1303 versus AMD's 951, a 27% difference, which speaks to better 2D desktop and windowing performance.

The AMD card's most significant victory comes in the Passmark GPU Compute test. Here, the RX 6700 XT scores 9,336, which is 11.2% higher than the RTX PRO 2000 Blackwell's 8,396. This is a notable win for AMD, showing its compute shader performance is still competitive. In the 3DMark Steel Nomad DX12 test, the AMD card edges out a win with a score of 2,435 versus 2,374.5, a narrow 2.5% margin that shows the two are closely matched in this modern DX12 gaming benchmark.

The remaining head-to-head results are extremely close, with margins under 4%. In Passmark DirectX 11, the NVIDIA card wins by a hair, 174 to 173, a 0.6% difference. In Passmark DirectX 12, NVIDIA wins again, 80 to 77, a 3.7% margin. The AMD card takes the Passmark DirectX 10 test 124 to 122 (1.6% win) and the DirectX 9 test 242 to 241 (0.4% win). Finally, in the Passmark G3D test, the NVIDIA card wins 20,049 to 19,786, a 1.3% lead. These results indicate that for legacy DirectX titles and general 3D rendering, the performance is effectively a tie.

Architecture Differences

The architectural divide between these two GPUs is stark. The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture using a 7 nm process at TSMC, while the NVIDIA RTX PRO 2000 Blackwell uses the Blackwell 2.0 architecture on a more advanced 5 nm process, also from TSMC. This process advantage is reflected in the transistor density: the NVIDIA chip packs 121.0M transistors per mm² on its 181 mm² die (totaling 21,900 million transistors), whereas the AMD chip has 51.3M transistors per mm² on a larger 335 mm² die (totaling 17,200 million transistors).

The core configurations tell different stories. The AMD card has 2,560 shading units, 160 texture mapping units (TMUs), and 64 render output units (ROPs). It also features 40 ray tracing (RT) cores. The NVIDIA card, in contrast, has a much higher count of 4,352 shading units but fewer TMUs (136) and ROPs (48). It has 34 RT cores and also includes 136 tensor cores, which the AMD card lacks entirely. This core layout suggests the NVIDIA card is designed for massively parallel workloads that can use its higher shader count, while the AMD card focuses on a more balanced traditional pipeline.

Memory is another major point of divergence. The RX 6700 XT uses 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 384.0 GB/s. The RTX PRO 2000 Blackwell uses 16 GB of the newer GDDR7 memory on a narrower 128-bit bus, resulting in a lower bandwidth of 288.0 GB/s. This means the AMD card has a significant memory bandwidth advantage, while the NVIDIA card offers more capacity for larger datasets.

Clock speeds and power consumption are also worlds apart. The AMD card has a base clock of 2321 MHz and a boost clock of 2581 MHz, with a thermal design power (TDP) of 230 W. The NVIDIA card has a much lower base clock of 982 MHz but boosts to 1957 MHz, all while drawing a remarkably low 70 W TDP. This efficiency is a key architectural achievement for the Blackwell design.

The Verdict

The data presents a clear, albeit nuanced, verdict. For users whose primary workload involves compute, the NVIDIA RTX PRO 2000 Blackwell is the only logical choice. Its 58.4% lead in Geekbench OpenCL and 17.9% lead in Geekbench Vulkan are decisive and will translate directly into faster rendering and processing times in professional applications. The added 16 GB of memory and tensor cores further cement its position as the superior compute and AI workstation card.

For users focused on gaming or more traditional graphics workloads, the choice is less clear. The AMD RX 6700 XT wins the latest 3DMark DX12 test by 2.5% and has a significant 11.2% lead in Passmark GPU Compute. However, the NVIDIA card wins the Passmark G3D test by 1.3% and is essentially tied across all DirectX 9, 10, 11, and 12 legacy tests. The AMD card does have a major advantage in memory bandwidth (384.0 GB/s vs 288.0 GB/s), which can help in high-resolution gaming, and it has a higher pixel rate of 165.2 GPixel/s versus 93.94 GPixel/s, which is beneficial for fill-rate-bound scenarios.

The real differentiator might be the system-level impact. The NVIDIA card's 70 W TDP and no power connectors, requiring only a 250 W suggested PSU, make it ideal for compact, low-power workstations. The AMD card, with its 230 W TDP, dual power connectors (1x 6-pin + 1x 8-pin), and a 550 W suggested PSU, needs a more robust power supply and case with good airflow.

Where Each One Wins

The AMD Radeon RX 6700 XT is the winner in scenarios that prioritize high memory bandwidth and high fill rates. Its 384.0 GB/s of bandwidth and 165.2 GPixel/s pixel rate are its strongest assets. It wins the 3DMark Steel Nomad DX12 test by 2.5%, the Passmark GPU Compute test by 11.2%, and the legacy DirectX 9 and 10 tests. This suggests it is the better choice for users who play modern DX12 games, use applications that are sensitive to memory bandwidth, or run compute workloads that are not heavily optimized for NVIDIA's architecture. Its higher texture rate of 413.0 GTexel/s also makes it suitable for texture-heavy scenes.

The NVIDIA RTX PRO 2000 Blackwell is the clear winner in professional, compute-intensive, and low-power scenarios. Its 58.4% lead in OpenCL is its headline feature, followed by a 17.9% lead in Vulkan. The 16 GB of GDDR7 memory provides more headroom for large datasets, and the 136 tensor cores open up AI acceleration capabilities. Its 70 W TDP and compact 167 mm length make it perfect for small-form-factor workstations where power and space are at a premium. It wins the G2D test by 27%, indicating snappier desktop performance, and it also takes the Passmark G3D test by 1.3%. For any user whose primary concern is compute performance, professional rendering, or building a quiet, efficient, and small workstation, the NVIDIA card is the definitive choice.
