AMD Radeon Pro WX 9100 vs NVIDIA GB10 Comparison

Head-to-Head Benchmarks

The NVIDIA GB10 dominates the AMD Radeon Pro WX 9100 in every recorded benchmark. In Geekbench OpenCL, the GB10 scores 120,137 against 66,605 for the WX 9100, a decisive 80.4% advantage. The gap widens further in Geekbench Vulkan, where the GB10 reaches 114,648 while the WX 9100 manages 54,711, resulting in a 109.6% lead. These are not marginal differences; the GB10 more than doubles the older AMD card's Vulkan performance.

The average benchmark score tells the same story. The GB10 sits at 117,393, while the WX 9100 averages 64,212. That places the GB10 at the 95th percentile of all GPUs in the database, whereas the WX 9100 lands at the 89th percentile. The GB10's nearest rivals include the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (only 0.3% behind) and the AMD Radeon PRO W7700 at 118,976 (1.3% ahead). The WX 9100, by contrast, competes with much lower-tier cards: the NVIDIA CMP 30HX trails by just 0.6%, and the AMD Radeon RX 9060 XT LP is 0.6% behind. The WX 9100's closest competitor, the AMD Radeon Pro Vega 56, sits 0.8% behind.

What stands out is the magnitude of the OpenCL and Vulkan deltas. A 80.4% OpenCL gap and a 109.6% Vulkan gap indicate fundamental performance stratification, not iterative improvement. The GB10 is in a different performance class entirely. Even the WX 9100's strongest result, its OpenCL score of 66,605, falls roughly 45% short of the GB10's Vulkan score of 114,648. No benchmark in the database shows the WX 9100 winning or even coming close.

Where Each One Wins

The data records two head-to-head benchmarks, and the NVIDIA GB10 wins both. There are no categories where the AMD Radeon Pro WX 9100 takes the lead. In OpenCL, a compute-oriented API used across diverse workloads, the GB10's 120,137 score reflects a 80.4% advantage. In Vulkan, which targets graphics and compute with lower overhead, the GB10's 114,648 score represents a 109.6% lead.

For workloads that rely on OpenCL compute, the GB10 is the stronger choice by a wide margin. For Vulkan-based applications, the GB10's dominance is even more pronounced. The WX 9100's best showing is in OpenCL, where it reaches 66,605, but that is still far behind the GB10's worst recorded result. The data offers no scenario where the WX 9100 outperforms the GB10.

The WX 9100 does have a Metal benchmark score of 71,319, but the GB10 has no recorded Metal result, so no direct comparison is possible from the database. Similarly, the GB10 has no DirectX, OpenGL, or Vulkan API support listed (all marked as N/A), while the WX 9100 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. However, in the two shared benchmark tests, the GB10 wins outright.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing approaches. The NVIDIA GB10 uses the GB20B chip based on Blackwell 2.0 architecture, built on a 5 nm process at TSMC with a die size of 382 mm². The AMD Radeon Pro WX 9100 uses the Vega 10 chip based on GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries with a larger die of 495 mm². The WX 9100 packs 12,500 million transistors with a density of 25.3M per mm², while the GB10's transistor count is unknown.

Clock speeds differ substantially. The GB10 runs at a base clock of 1665 MHz and boosts to 2418 MHz. The WX 9100 starts at 1200 MHz and boosts to 1500 MHz. The GB10's memory clock is listed as 1067 MHz (8.5 Gbps effective), while the WX 9100's memory runs at 945 MHz (1890 Mbps effective).

Memory configurations are radically different. The GB10 carries 128 GB of LPDDR5X on a 256-bit bus, yielding 273.2 GB/s of bandwidth. The WX 9100 has 16 GB of HBM2 on a 2048-bit bus, delivering 483.8 GB/s. The WX 9100 actually provides significantly higher memory bandwidth, 483.8 GB/s versus 273.2 GB/s, despite having far less capacity. The 2048-bit bus is a legacy high-bandwidth design, while the GB10 trades some bandwidth for much larger capacity.

Compute resources favor the GB10. It has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 384 tensor cores. The WX 9100 has 4096 shading units, 256 TMUs, and 64 ROPs, with no RT cores or tensor cores listed. The GB10's pixel rate is 116.1 GPixel/s versus 96.00 GPixel/s for the WX 9100. Texture rate is 928.5 GTexel/s versus 384.0 GTexel/s. FP32 throughput is 29.71 TFLOPS for the GB10 and 12.29 TFLOPS for the WX 9100. In FP16, the GB10 delivers 29.71 TFLOPS (1:1 ratio), while the WX 9100 reaches 24.58 TFLOPS (2:1 ratio).

Power and physical design diverge sharply. The GB10 has a 140 W TDP, is an IGP form factor, requires no power connectors, and suggests a 300 W PSU. The WX 9100 has a 230 W TDP, is dual-slot, needs 1x 6-pin plus 1x 8-pin power connectors, and suggests a 550 W PSU. The GB10 measures 150 mm in length, 51 mm in height, and 150 mm in width. The WX 9100 is 267 mm long and 111 mm high. The GB10 uses PCIe 5.0 x16, while the WX 9100 uses PCIe 3.0 x16. Display outputs also differ: the GB10 has 1x HDMI, while the WX 9100 has 6x mini-DisplayPort 1.4a.

The Verdict

The data points to a clear conclusion: the NVIDIA GB10 is the superior performer in every measured category. Its 80.4% OpenCL lead and 109.6% Vulkan lead leave no ambiguity. The GB10 sits at the 95th percentile of all GPUs, while the WX 9100 sits at the 89th. The GB10's nearest rivals are modern workstation cards like the RTX 4000 SFF Ada Generation and Radeon PRO W7700, both within a few percentage points. The WX 9100's nearest rivals are lower-tier cards like the CMP 30HX and RX 9060 XT LP.

For compute-heavy workloads using OpenCL or Vulkan, the GB10 is the obvious choice. Its FP32 throughput of 29.71 TFLOPS more than doubles the WX 9100's 12.29 TFLOPS. The GB10 also brings ray tracing and tensor cores, which the WX 9100 lacks entirely. The GB10's 128 GB memory capacity is unmatched by the WX 9100's 16 GB, making it suitable for large datasets.

The WX 9100 does retain advantages in specific areas. Its memory bandwidth of 483.8 GB/s exceeds the GB10's 273.2 GB/s. It offers six display outputs versus one HDMI on the GB10. It supports DirectX 12, OpenGL 4.6, and Vulkan 1.3, while the GB10 lists N/A for all three APIs. The WX 9100 is also a dual-slot card with a standard PCIe 3.0 x16 interface, whereas the GB10 is an IGP with PCIe 5.0 x16.

The GB10 is an active product released in late 2025, while the WX 9100 is end-of-life, launched in 2017. The GB10's predecessor is Server Hopper, and its successor is Server Rubin. The WX 9100's predecessor is Radeon Pro GCN, and its successor is Radeon Pro Vega. The production status difference reinforces the benchmark results: the GB10 is current-generation hardware with a 5 nm process, while the WX 9100 is a 14 nm legacy product.

Buyers needing maximum compute performance, ray tracing, tensor acceleration, or massive memory capacity should choose the NVIDIA GB10. Buyers with workloads that depend on high memory bandwidth or multiple display outputs, or that require legacy API support, may find the AMD Radeon Pro WX 9100 relevant, but they must accept a large performance deficit.
