Q: Are both cards still in production?

A: No. The NVIDIA RTX 2000 Ada Generation is listed as "Active" in production status, while the AMD Radeon PRO W6600 is marked as "End-of-life." The AMD card was released on 2021-06-07, whereas the NVIDIA card is newer, with a release date of 2024-02-11.

Q: Which card has a higher pixel fill rate?

A: The AMD Radeon PRO W6600 has a significantly higher pixel rate of 165.1 GPixel/s, compared to the NVIDIA RTX 2000 Ada Generation's 102.2 GPixel/s. This suggests the AMD card may handle certain rasterization tasks faster.

The Verdict

The benchmark data presents a split decision. For professionals prioritizing raw compute in OpenCL-heavy applications, the NVIDIA RTX 2000 Ada Generation is the clear choice, offering a 16.7% performance advantage in that specific test. Its 16 GB VRAM also doubles the capacity of the AMD rival, making it better suited for large datasets and high-resolution textures. The NVIDIA card achieves this with a drastically lower TDP of 70 W, a smaller physical footprint (168 mm vs 241 mm), and a newer, more efficient architecture.

Conversely, the AMD Radeon PRO W6600 wins the overall average score race by 1.6% and edges out the NVIDIA card in Vulkan by a slim 0.7%. It also boasts superior pixel and texture rates (165.1 GPixel/s and 289.0 GTexel/s vs 102.2 GPixel/s and 187.4 GTexel/s), which could benefit traditional 3D rendering pipelines. However, its 8 GB memory capacity is a limiting factor for modern workloads, and its end-of-life status makes it a less future-proof investment. The data suggests the NVIDIA card is the better choice for new builds focused on compute and memory capacity, while the AMD card still holds its own in specific rendering tasks but is harder to recommend given its production status and lower VRAM.

Head-to-Head Benchmarks

The two cards split their head-to-head benchmark wins, with each securing one victory. The most significant divergence appears in Geekbench OpenCL, where the NVIDIA RTX 2000 Ada Generation posts a score of 85370 against the AMD Radeon PRO W6600's 73151. This 16.7% lead for NVIDIA is substantial and indicates a strong advantage in general-purpose GPU compute tasks that leverage OpenCL. For users running simulations, data processing, or other compute-accelerated applications, this delta is the primary differentiator.

In contrast, the Geekbench Vulkan test shows a much closer contest. The AMD Radeon PRO W6600 scores 78993, slightly ahead of the NVIDIA RTX 2000 Ada Generation's 78461, a marginal 0.7% difference. While this is a win for AMD, the single-digit percentage gap is within the noise of typical benchmark variance, suggesting that Vulkan performance is effectively a tie between the two. The data indicates that NVIDIA dominates in one major compute API while AMD maintains a razor-thin lead in the other, making the choice dependent on the software ecosystem the user relies on.

Specification Differences

The two cards diverge significantly on core specifications beyond their shared 128-bit memory bus and PCIe 4.0 x8 interface. The NVIDIA RTX 2000 Ada Generation features 2816 shading units, 88 TMUs, and 48 ROPs, along with 22 RT cores and 88 tensor cores. In contrast, the AMD Radeon PRO W6600 has fewer shading units (1792) and TMUs (112) but more ROPs (64) and RT cores (28). The AMD card does not list any tensor cores.

Clock speeds also tell a different story. The AMD card runs at a higher base clock of 2331 MHz and a boost clock of 2580 MHz, compared to the NVIDIA card's 1620 MHz base and 2130 MHz boost. However, the NVIDIA card compensates with a superior FP32 compute rating of 12.00 TFLOPS versus the AMD card's 9.247 TFLOPS. Memory configurations differ as well: the NVIDIA card offers 16 GB at 16 Gbps effective for 256.0 GB/s bandwidth, while the AMD card has 8 GB at 14 Gbps effective for 224.0 GB/s. Physical specifications also vary, with the NVIDIA card being a dual-slot 168 mm design with no power connectors, and the AMD card being a single-slot 241 mm design requiring a 1x 6-pin connector.

Architecture Differences

The architectural gap between these two GPUs is generational. The NVIDIA RTX 2000 Ada Generation is built on the Ada Lovelace architecture using the AD107 chip, manufactured on a 5 nm process at TSMC. This process node allows for a transistor density of 118.9M / mm², packing 18,900 million transistors into a 159 mm² die. In contrast, the AMD Radeon PRO W6600 uses the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process, also by TSMC. This older node results in a lower transistor density of 46.7M / mm², with 11,060 million transistors spread across a larger 237 mm² die.

The compute feature sets also differ. The NVIDIA card's Ada Lovelace architecture includes dedicated tensor cores, which are absent from the AMD card, making the RTX 2000 Ada a better fit for AI-accelerated workflows. The AMD card's RDNA 2.0 architecture offers FP16 performance at a 2:1 ratio (18.49 TFLOPS) compared to its FP32 rate, whereas the NVIDIA card runs FP16 at a 1:1 ratio with FP32 (12.00 TFLOPS for both). Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but their underlying silicon designs cater to different workload strengths.

Where Each One Wins

The NVIDIA RTX 2000 Ada Generation wins in scenarios demanding raw compute throughput and large memory capacities. Its 16.7% OpenCL lead makes it the superior choice for compute-intensive applications, and its 16 GB of VRAM is double that of the AMD card, providing headroom for larger models, complex scenes, or multi-application workflows. The lower TDP of 70 W and its compact 168 mm length also make it ideal for small form-factor builds or environments where heat and power are constrained. The presence of tensor cores gives it an edge in any workload that can leverage AI acceleration.

The AMD Radeon PRO W6600 wins in specific rendering-oriented tasks that benefit from its higher pixel and texture rates. Its 165.1 GPixel/s pixel rate and 289.0 GTexel/s texture rate are significantly higher than the NVIDIA card's figures, suggesting it can push more geometry and fill in traditional 3D rendering pipelines. Its single-slot design (241 mm) may also be preferable in chassis with limited slot spacing, despite being longer. The AMD card's 0.7% Vulkan win, while minimal, indicates it holds its own in Vulkan-based applications. However, its 8 GB memory and end-of-life status are notable drawbacks that limit its long-term viability for future workloads.
