AMD Radeon PRO W7700 vs NVIDIA RTX 4000 Ada Generation Comparison

NVIDIA’s RTX 4000 Ada Generation and AMD’s Radeon PRO W7700 are both 5 nm workstation cards aimed at similar professional workloads, but the benchmark data shows they excel in different compute APIs. The RTX 4000 Ada carries a decisive lead in OpenCL performance, while the Radeon PRO W7700 counters in Vulkan. Both cards sit at the 95th percentile of all GPUs, yet their average scores diverge by roughly 12%, indicating that the choice between them hinges on the specific software stack and rendering API used in your workflow.

Head-to-Head Benchmarks

The single largest performance gap between these two cards appears in the Geekbench OpenCL test. The NVIDIA RTX 4000 Ada Generation scores 146,593, while the AMD Radeon PRO W7700 manages 108,245. That translates to a 35.4% advantage for the NVIDIA card in this particular benchmark. For context, the RTX 4000 Ada’s average benchmark score across all tests is 135,218, which places it just 0.9% behind the AMD Radeon PRO V620 in its nearest rival list. The W7700’s OpenCL result is closer to the NVIDIA RTX 4000 SFF Ada Generation (which scores 117,088 on average) than it is to the full-size RTX 4000 Ada.

The Vulkan benchmark flips the script. Here, the AMD Radeon PRO W7700 scores 129,706, edging out the RTX 4000 Ada’s 123,842 by 4.5%. This is a narrower margin than NVIDIA’s OpenCL win, but it is still a clear victory for AMD in the Vulkan API. The W7700’s average benchmark score of 118,976 is 1.3% ahead of the NVIDIA GB10 and 1.6% ahead of the RTX 4000 SFF Ada Generation, showing that its Vulkan strength is not an anomaly—it consistently outperforms several NVIDIA workstation parts in aggregate terms.

When you average the two benchmark results, the RTX 4000 Ada comes out ahead overall. Its combined average score of 135,218 versus the W7700’s 118,976 represents a 13.6% gap. The delta between the two cards in the head-to-head Vulkan test (-4.5%) is far smaller than the delta in OpenCL (+35.4%), meaning the NVIDIA card’s overall lead is driven almost entirely by its massive OpenCL advantage. If your applications rely heavily on OpenCL, the RTX 4000 Ada is the clear winner. If Vulkan is your primary API, the W7700 offers a modest but real performance edge.

The Verdict

The data points to a straightforward recommendation: pick the NVIDIA RTX 4000 Ada Generation if your workloads are OpenCL-heavy, and pick the AMD Radeon PRO W7700 if you live in Vulkan-based applications. The RTX 4000 Ada’s 35.4% lead in OpenCL is too large to ignore for compute tasks that use that API. It also has 20 GB of memory versus the W7700’s 16 GB, which matters for large datasets even if raw bandwidth is lower.

However, the W7700 is not a weak card. Its Vulkan win, while smaller, demonstrates that AMD’s RDNA 3.0 architecture handles that API efficiently. The W7700 also has a higher boost clock (2600 MHz vs 2175 MHz) and a wider memory bus (256-bit vs 160-bit), which contribute to its higher memory bandwidth of 576 GB/s versus 360 GB/s. For professionals using Vulkan-based renderers or game engines, the W7700’s 4.5% advantage is meaningful but not overwhelming. Given that both cards are at the 95th percentile of all GPUs, neither is a poor choice—the decision comes down to which API dominates your particular software suite.

Architecture Differences

The two cards are built on the same 5 nm TSMC process node but use fundamentally different architectures. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip with Ada Lovelace architecture, featuring 35,800 million transistors on a 294 mm² die. The AMD Radeon PRO W7700 uses the Navi 32 chip with RDNA 3.0 architecture, packing 28,100 million transistors on a larger 346 mm² die. This means NVIDIA achieves a higher transistor density of 121.8M per mm² versus AMD’s 81.2M per mm².

The compute layouts differ substantially. The RTX 4000 Ada has 6,144 shading units, 192 TMUs, and 64 ROPs, while the W7700 has 3,072 shading units, 192 TMUs, and 96 ROPs. This explains the RTX 4000 Ada’s higher FP32 throughput in some tests, though the W7700’s FP32 rating is actually higher at 31.95 TFLOPS versus 26.73 TFLOPS. The W7700 also doubles its FP16 performance to 63.90 TFLOPS with a 2:1 ratio, while the RTX 4000 Ada maintains a 1:1 ratio at 26.73 TFLOPS.

Ray tracing hardware is present on both cards, with each featuring 48 RT cores. The RTX 4000 Ada adds 192 tensor cores, which the W7700 lacks entirely—a notable difference for AI-accelerated workloads. Memory configurations also diverge: the RTX 4000 Ada offers 20 GB of GDDR6 on a 160-bit bus, while the W7700 has 16 GB on a 256-bit bus. The W7700 compensates for less capacity with significantly higher bandwidth (576 GB/s vs 360 GB/s). The RTX 4000 Ada uses a single 16-pin power connector with a 130 W TDP and 300 W suggested PSU, while the W7700 uses an 8-pin connector with a 190 W TDP and 450 W suggested PSU.

Its 146,593 OpenCL score beats the W7700 by 35.4%, making it the obvious choice for compute tasks that leverage OpenCL—common in scientific simulation, some rendering pipelines, and certain CAD applications. The 20 GB memory capacity also gives it an edge for models or scenes that exceed 16 GB, even if its 360 GB/s bandwidth is lower. The presence of 192 tensor cores further positions it for AI inference or deep learning tasks that can use those accelerators.

The AMD Radeon PRO W7700 wins in Vulkan, with a 129,706 score that is 4.5% higher than the RTX 4000 Ada. This makes it the better option for Vulkan-based game engines, real-time renderers, and modern graphics APIs. Its higher memory bandwidth (576 GB/s) and wider 256-bit bus provide an advantage in bandwidth-sensitive tasks, even with less total memory. The W7700’s higher FP32 and FP16 throughput (31.95 and 63.90 TFLOPS, respectively) also suggest it can handle certain compute loads faster, provided the software uses those paths efficiently. For professionals whose primary tools are Vulkan-based, the W7700 delivers better performance per the data.

Specification Differences

The two cards differ across nearly every major specification. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip with Ada Lovelace architecture, while the AMD Radeon PRO W7700 uses Navi 32 with RDNA 3.0. Transistor counts are 35,800 million for NVIDIA versus 28,100 million for AMD, with die sizes of 294 mm² and 346 mm² respectively. The RTX 4000 Ada has more shading units (6,144 vs 3,072) and same TMUs (192 each), but fewer ROPs (64 vs 96).
