AMD Radeon PRO W7700 vs NVIDIA GB10 Comparison

# AMD Radeon PRO W7700 vs NVIDIA GB10

The AMD Radeon PRO W7700 and NVIDIA GB10 represent two fundamentally different approaches to GPU computing, yet their average benchmark scores land within 1.3% of each other. The AMD card edges ahead with an average benchmark score of 118,976 versus 117,393 for the NVIDIA part, a delta of just 1.3%. Both sit at the 95th percentile of all GPUs, placing them in the same performance tier overall. However, the data reveals that these two devices win in completely opposite workloads—AMD dominates Vulkan by 13.1%, while NVIDIA wins OpenCL by 9.9%. The GB10 is also a much newer product, releasing on 2025-10-14 compared to the W7700's 2023-11-12 release, and carries a launch MSRP of 3,999 USD versus 999 USD for the AMD card.

The Verdict

The data points to a clear split based on workload and form factor. For users running Vulkan-based applications, the AMD Radeon PRO W7700 is the obvious choice—its 129,706 Vulkan score crushes the GB10's 114,648, a 13.1% advantage that is substantial in real-world rendering terms. The W7700 also offers a full dual-slot PCIe card with four DisplayPort 2.1 outputs, making it suitable for multi-monitor professional workstations.

For OpenCL-heavy compute tasks, the NVIDIA GB10 takes the lead with 120,137 versus 108,245, a 9.9% margin. The GB10's massive 128 GB of LPDDR5X memory dwarfs the W7700's 16 GB GDDR6, and its 140 W TDP with no power connectors makes it viable for integrated form factors. However, the GB10's IGP slot width and single HDMI output suggest it targets embedded or server chassis rather than traditional desktop workstations.

Budget-conscious buyers should note the price disparity—999 USD versus 3,999 USD launch MSRP—but the benchmark data does not justify the fourfold price difference unless the 128 GB memory capacity or the GB10's specific compute profile is essential. The W7700 delivers comparable average performance at a fraction of the cost, winning one benchmark and losing the other by similar margins.

Architecture Differences

The architectural gap between these two GPUs is generational and philosophical. AMD's W7700 uses the Navi 32 chip built on RDNA 3.0 architecture with a 5 nm TSMC process, packing 28,100 million transistors into a 346 mm² die. The GB10 uses the GB20B chip on Blackwell 2.0 architecture, also on a 5 nm TSMC process, but with a slightly larger 382 mm² die and unspecified transistor count.

The shading unit counts tell a fascinating story. The GB10 has 6,144 shading units—exactly double the W7700's 3,072—yet the AMD card achieves higher FP32 throughput at 31.95 TFLOPS versus 29.71 TFLOPS. This is explained by clock speeds: the W7700 boosts to 2600 MHz while the GB10 reaches only 2418 MHz. The GB10 compensates with 384 TMUs versus 192, delivering 928.5 GTexel/s compared to 499.2 GTexel/s.

Memory architecture differs dramatically. The W7700 uses 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth, while the GB10 uses 128 GB of LPDDR5X on the same 256-bit bus but with only 273.2 GB/s—less than half the bandwidth. The GB10's memory clock runs at 1067 MHz (8.5 Gbps effective) versus the W7700's 2250 MHz (18 Gbps effective). This suggests the GB10 prioritizes capacity for large datasets over raw throughput.

The GB10 includes 384 tensor cores while the W7700 has none listed. Both have 48 RT cores, though the GB10 has half the ROPs (48 versus 96), resulting in a much lower pixel rate of 116.1 GPixel/s versus 249.6 GPixel/s. The GB10 also supports PCIe 5.0 x16 versus the W7700's PCIe 4.0 x16, and it lacks DirectX, OpenGL, and Vulkan API support entirely—a critical limitation for traditional graphics workloads.

Head-to-Head Benchmarks

The two available benchmarks split evenly, one win each, but the margins tell different stories. In Geekbench OpenCL, the NVIDIA GB10 posts 120,137 against the AMD W7700's 108,245. The 9.9% delta in NVIDIA's favor is significant but not overwhelming. This result aligns with the GB10's higher shading unit count and tensor core presence, which likely benefit compute-heavy OpenCL workloads.

In Geekbench Vulkan, the AMD W7700 dominates with 129,706 versus 114,648 for the GB10—a 13.1% advantage. The W7700's higher pixel rate (249.6 GPixel/s versus 116.1 GPixel/s) and greater memory bandwidth (576.0 GB/s versus 273.2 GB/s) likely contribute to this graphics-oriented win. The Vulkan score also suggests the W7700's RDNA 3.0 architecture is more efficient at translating raw FP32 throughput into actual rendering performance.

The average benchmark scores reflect this split: the W7700's average of 118,976 beats the GB10's 117,393 by 1.3%, but this masks the workload-specific divergence. Notably, the GB10's nearest rival is the RTX 4000 SFF Ada Generation at 117,088 (0.3% behind), while the W7700's closest rival is the GB10 itself (1.3% behind). Both GPUs outperform the Tesla V100 SXM2 16 GB by 4% and the RTX A5500 Mobile by 4.4% in their respective rival lists.

Where Each One Wins

The AMD Radeon PRO W7700 wins in scenarios that demand graphics API support and rasterization throughput. Its Vulkan score of 129,706 is the standout performance metric, 13.1% ahead of the GB10. The dual-slot form factor, four DisplayPort 2.1 outputs, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support make it suitable for professional visualization, CAD, and content creation workloads. The higher pixel rate of 249.6 GPixel/s and bandwidth of 576.0 GB/s reinforce this graphics-first profile. Its 999 USD launch MSRP also makes it the economically rational choice for most workstation buyers.

The NVIDIA GB10 wins in compute-heavy OpenCL workloads, posting 120,137 versus 108,245—a 9.9% margin. Its 128 GB of LPDDR5X memory is the defining feature, offering eight times the capacity of the W7700 for large datasets, machine learning inference, or in-memory processing. The 384 tensor cores provide dedicated AI acceleration hardware that the W7700 lacks entirely. The IGP form factor with 140 W TDP and no power connectors enables deployment in embedded systems or dense server chassis where space and power are constrained. However, the lack of DirectX, OpenGL, and Vulkan API support excludes it from traditional graphics workloads, and its 3,999 USD launch MSRP is four times higher than the AMD alternative.

The data suggests a simple decision rule: if the workload is graphics-centric and requires standard APIs, the W7700 is the superior choice at a fraction of the cost. If the workload demands massive memory capacity or tensor core acceleration in a low-power embedded form factor, the GB10 justifies its premium despite the benchmark split.
