AMD Radeon Pro WX 4100

The AMD Radeon Pro WX 4100 is an end-of-life professional graphics card built on the Baffin chip with GCN 4.0 architecture, fabricated on GlobalFoundries' 14 nm process. It packs 3,000 million transistors on a 123 mm² die, yielding a transistor density of 24.4 million per square millimeter. With a 50 W TDP and a single-slot, low-profile-friendly design, it targets compact workstations and legacy professional environments. The card launched with an MSRP of 399 USD, but its current relevance is defined by its benchmark standing: it sits at the 35th percentile among all GPUs, with an average benchmark score of 6309. That places it in the same performance tier as several older mainstream and entry-level workstation cards, as detailed below.

Benchmark Performance

The Radeon Pro WX 4100’s compute and graphics scores reveal a card that is firmly in the entry-level professional segment, yet still competitive with a handful of older desktop parts. Its Geekbench Metal score of 20980 and OpenCL score of 17608 are respectable for a 2016-era GPU, while the Vulkan result of 18563 indicates moderate API efficiency. In Passmark, the card achieves 3699 in G3D and 1475 in GPU compute, with legacy DirectX tests showing 56 in DX9, 24 in DX11, 22 in DX12, and 16 in DX10. The G2D score of 646 suggests adequate 2D performance for desktop and CAD-style tasks.

Against its nearest rivals, the WX 4100 is nearly indistinguishable in raw average score. The NVIDIA GeForce GTX 460 SE averages 6326, just 0.3% higher than the WX 4100’s 6309, meaning the AMD card is effectively tied with that older gaming GPU. The AMD Radeon R7 M350 is 0.3% lower at 6290, and the NVIDIA Quadro K620 is 0.4% higher at 6286. The most notable comparison is with the NVIDIA Quadro P2000, which averages 6364 — only 0.9% ahead. This tight cluster (all within roughly one percentage point) indicates that the WX 4100 delivers performance on par with mid-range cards from several generations ago, but it does not meaningfully outperform any of them. In practical terms, the data shows that for compute-heavy workloads, the WX 4100 will feel comparable to a Quadro K620 or a GTX 460 SE, but it will not match modern entry-level cards.

The 35th percentile ranking underscores that the WX 4100 falls in the lower third of all GPUs ever benchmarked. Its average score of 6309 is modest, and while it can handle light 3D modeling or older game engines, it will struggle with contemporary titles at high settings. The Passmark DirectX 12 score of 22 is particularly telling — it indicates limited modern API performance, though the card does support DirectX 12 (12_0) at a feature level that allows basic use.

Ray Tracing and Feature Set

The WX 4100 has no dedicated ray tracing cores and no tensor cores. It is a pure GCN 4.0 design with 1024 shading units, 64 texture mapping units, and 16 raster output units. This means hardware-accelerated ray tracing is completely absent; any ray-traced effects would have to be computed in software, which is impractical for real-time workloads. The card does support DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, so it can run modern APIs that include optional DXR or Vulkan Ray Tracing extensions — but without dedicated RT hardware, those features will be effectively unusable at interactive frame rates.

Compute performance is modest: FP32 throughput is 2.460 TFLOPS, and FP16 runs at the same rate (1:1). That is a useful detail for workloads that rely on single-precision math, but it is far below what modern cards offer. The card’s pixel rate is 19.22 GPixel/s and texture rate is 76.86 GTexel/s, which are consistent with its low-end positioning. For professional applications that rely on OpenGL (like older CAD tools) or Vulkan (for some engineering suites), the WX 4100 provides adequate baseline support, but it lacks the specialized hardware found in later Radeon Pro or NVIDIA RTX products.

On the display side, the card offers 4x mini-DisplayPort 1.4a outputs. This allows multi-monitor setups, and DisplayPort 1.4a supports high refresh rates and 4K output, though the GPU’s compute limits will constrain heavy 4K rendering. The lack of RT and tensor cores means the card is not suited for AI inference or machine learning tasks that rely on tensor acceleration.

Memory Subsystem

The WX 4100 comes with 4 GB of GDDR5 memory on a 128-bit bus, yielding a bandwidth of 96.00 GB/s. Memory clock is 1500 MHz, translating to 6 Gbps effective. For a professional card of this era, 4 GB is adequate for 2D CAD, light 3D modeling, and texture-heavy applications at 1080p, but it will become a bottleneck at 1440p or 4K with large textures or complex scenes. The 128-bit bus limits memory bandwidth compared to wider-bus cards; 96 GB/s is roughly half of what mid-range cards from the same generation offered. In practice, this means that the WX 4100 can handle moderate texture loads, but it will experience stuttering or reduced performance when VRAM usage exceeds 4 GB or when memory bandwidth is saturated.

For high-resolution work, the data suggests caution. The card’s memory bandwidth is sufficient for 1080p gaming at low to medium settings, but 4K rendering or large scientific datasets will quickly exceed the 4 GB capacity. The 96 GB/s bandwidth also limits the speed of data transfers between the GPU and VRAM, which can affect compute tasks that are memory-bound. In professional workflows, this card is best suited for 2D applications, spreadsheet-like GPU tasks, or older 3D scenes that fit within the 4 GB frame buffer.

Who Should Consider It

Based on benchmark results, the WX 4100 is best suited for users who need a low-power, single-slot professional card for 2D CAD, spreadsheet-heavy GPU compute, or legacy software that relies on OpenGL 4.6 or Vulkan 1.3. Its Passmark G3D score of 3699 and Geekbench OpenCL score of 17608 indicate it can handle basic 3D modeling at 1080p with reduced settings, but it is not a card for modern gaming or heavy rendering. The 35th percentile ranking places it below most contemporary GPUs, so anyone expecting smooth 1440p or 4K performance will be disappointed.

For 1080p gaming, the card can run older titles or new games at low settings, but the DirectX 12 score of 22 and the 4 GB VRAM limit make it a poor choice for current AAA releases. Professional users working with 2D schematics, PCB layout, or light photo editing will find the card sufficient, especially given its single-slot form factor and 50 W TDP. However, anyone needing ray tracing, AI acceleration, or high memory bandwidth should look elsewhere — the WX 4100 has none of those features. The tight performance parity with the Quadro K620 and GTX 460 SE suggests that the WX 4100 is essentially a rebadged or re-tuned version of those older architectures, so buyers should only consider it if they specifically require its display outputs (4x mini-DisplayPort 1.4a) or its compact physical profile.

Power and Cooling

The WX 4100 is extremely power-efficient, with a TDP of just 50 W. It requires no auxiliary power connectors, drawing all power from the PCIe slot. The suggested PSU rating is 250 W, which means even older or low-capacity power supplies can run this card without issue. Its single-slot design measures 168 mm in length (6.6 inches) and 69 mm in height (2.7 inches), making it suitable for small-form-factor or dense workstation builds. Because it has no external power connectors, installation is straightforward, and the low TDP means a passive or low-profile cooler is sufficient — though the card does have a fan for active cooling.

The lack of power connectors also simplifies cable management, and the 50 W TDP ensures minimal heat output inside the chassis. For systems with a 250 W PSU or higher, the WX 4100 will not strain the power delivery. Given its end-of-life status, users should verify driver support for their operating system, but the card’s low power draw and compact dimensions remain its most compelling attributes for legacy workstation upgrades.
