AMD Radeon Pro WX 4100 vs NVIDIA RTX PRO 6000 Blackwell Server Comparison

This comparison pits an end-of-life 2016 workstation card against a current-generation server-class compute accelerator. The data shows these are not direct competitors; they target entirely different workloads, power envelopes, and eras of graphics technology. The verdict is straightforward: the AMD Radeon Pro WX 4100 is a legacy entry-level professional GPU, while the NVIDIA RTX PRO 6000 Blackwell Server is a modern, high-performance compute monster.

The Verdict

The data dictates a clear split. For legacy 2D/3D professional workflows, light CAD, and multi-display setups in older systems, the AMD Radeon Pro WX 4100 remains a functional, low-power option. Its 50 W TDP and single-slot design make it easy to integrate into compact workstations. However, its 4 GB GDDR5 memory and GCN 4.0 architecture are severely outdated.

The NVIDIA RTX PRO 6000 Blackwell Server is the only choice for modern AI inference, high-resolution rendering, and massive parallel compute. With 96 GB of GDDR7 memory, 24,064 shading units, and dedicated RT and Tensor cores, it offers a generational leap. Its 126.0 TFLOPS FP32 performance versus the WX 4100's 2.460 TFLOPS is not an incremental gain; it is a 50-fold increase in raw compute throughput.

The benchmark data reflects this gulf. The RTX PRO 6000 scores 5,996 on 3DMark Steel Nomad, a test that the WX 4100 cannot even run. The WX 4100's highest modern benchmark is 21,018 on Geekbench Metal, which is an Apple-specific API. For any user needing to process large datasets, train models, or render complex scenes, the RTX PRO 6000 is the definitive pick. The WX 4100 should only be considered for maintaining legacy systems where its specific display outputs and low power draw are required.

Architecture Differences

The architectural gap between these two GPUs spans nearly a decade of process technology and design philosophy.

The AMD Radeon Pro WX 4100 is built on the Baffin chip using the GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 3,000 million transistors on a 123 mm² die, resulting in a transistor density of 24.4M per mm². It features 1,024 shading units, 64 TMUs, and 16 ROPs. Crucially, it has no dedicated RT cores or Tensor cores, meaning ray tracing and AI acceleration are handled entirely by the shader array, if at all. Its memory subsystem is a 128-bit bus with 4 GB of GDDR5, delivering 96.00 GB/s of bandwidth.

In stark contrast, the NVIDIA RTX PRO 6000 Blackwell Server is built on the GB202 chip using the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It contains a massive 92,200 million transistors on a 750 mm² die, achieving a transistor density of 122.9M per mm². This architecture is fundamentally different, incorporating 188 dedicated RT cores and 752 Tensor cores alongside its 24,064 shading units, 752 TMUs, and 192 ROPs. Its memory system is equally advanced, featuring a 512-bit bus with 96 GB of GDDR7, providing 1.79 TB/s of bandwidth.

The API support also differentiates them. The WX 4100 supports DirectX 12 (12_0) and Vulkan 1.3, while the RTX PRO 6000 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, enabling features like hardware ray tracing and mesh shaders that the older card cannot access.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are impossible because the two cards share no common test results in the data. The RTX PRO 6000 has a single benchmark result: 5,996 on 3Dmark_3dmark_steel_nomad_dx12. The WX 4100 has results for older APIs like Passmark DirectX 9, 10, 11, and 12, as well as Geekbench OpenCL, Vulkan, and Metal.

The data shows that the WX 4100's Passmark scores are exceptionally low, with its best DirectX result being 56 in DirectX 9. Its Passmark G3D score is 3,699, and its GPU Compute score is 1,475. These numbers are typical for an entry-level card from 2016. In contrast, the RTX PRO 6000's Steel Nomad score of 5,996 is a modern, demanding benchmark that stresses ray tracing and DirectX 12 Ultimate features.

The nearest rivals for the WX 4100 are the AMD Radeon R7 M350 (0.1% ahead), NVIDIA Quadro K620 (0.8% ahead), and NVIDIA GeForce GTX 460 SE (0.9% behind). This places the WX 4100 in the same performance tier as decade-old mobile and entry-level desktop GPUs. The RTX PRO 6000's nearest rivals are the NVIDIA GeForce GTX 770M (0.1% behind) and AMD Radeon RX 6400 (0.1% behind), which is surprising. This suggests that its single benchmark result may not fully capture its peak compute capabilities, or that the Steel Nomad test is heavily driver-dependent. Nevertheless, the architectural and spec differences make the performance gap obvious.
