AMD Radeon Pro WX 3100

The AMD Radeon Pro WX 3100 is a mobile and small-form-factor workstation graphics card built on the 14 nm GCN 4.0 architecture, featuring the Lexa chip with 2,200 million transistors on a 103 mm² die. With an average benchmark score of 9,738, it sits at the 46th percentile of all GPUs, placing it as a modest entry-level professional solution. The data indicates a card designed for basic CAD, light 3D modeling, and multi-display productivity, rather than high-end compute or gaming workloads.

Memory Subsystem

The Radeon Pro WX 3100 is equipped with 4 GB of GDDR5 memory on a 128-bit bus, yielding a memory bandwidth of 96.00 GB/s. This configuration is modest by modern standards, and the data suggests it is a limiting factor for high-resolution textures or large datasets. At 1080p, the capacity is workable for typical workstation applications, but the bandwidth figure translates to potential bottlenecks when handling complex scenes or multi-layer compositing. For 1440p and above, the 4 GB capacity combined with the 128-bit interface will likely force reliance on memory compression and reduced texture quality. The effective memory clock of 6 Gbps is standard for GDDR5 of this era, but the narrow bus width keeps peak throughput low, making this card better suited to 2D drafting and light 3D previews rather than heavy GPU-accelerated rendering.

Ray Tracing and Feature Set

The WX 3100 does not contain dedicated ray tracing or tensor cores, as its GCN 4.0 architecture predates such hardware. Instead, it relies on 512 shading units, 32 texture mapping units, and 16 ROPs for all graphics work. The API support is solid for its class: DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3 are all present. This means the card can run modern applications that use these APIs, but without hardware RT acceleration, any ray-traced effects would be processed on the shader units, yielding poor performance. The pixel rate of 19.50 GPixel/s and texture rate of 39.01 GTexel/s are consistent with the low ROP and TMU counts. For professional workloads, the feature set is adequate for OpenGL-based CAD and Vulkan compute, but the absence of RT/tensor cores makes it unsuitable for AI inference or real-time path tracing.

How It Compares

NVIDIA Tesla C2070

The WX 3100 scores 0.2% higher than the Tesla C2070’s average of 9,716. This is a negligible margin, effectively a statistical tie. The Tesla C2070 is a much older Fermi-based compute card, so the WX 3100’s newer architecture and lower power draw make it more practical, though compute-heavy tasks may still favor the Tesla’s larger memory interface in specific legacy workloads.

AMD Radeon Pro WX 2100

Against its direct sibling, the WX 3100 leads by 0.7%, with the WX 2100 scoring 9,675. The performance gap is small, but the WX 3100 offers higher memory bandwidth (96.00 GB/s versus the 2100’s narrower configuration) based on the fact pack. For users choosing between the two, the WX 3100’s edge in both raw score and memory throughput makes it the better pick for texture-heavy tasks.

NVIDIA GeForce GTX 960M

The WX 3100 also beats the GTX 960M by 0.7%, with the latter scoring 9,670. The GTX 960M is a consumer mobile GPU, so the WX 3100’s advantage in workstation drivers and display outputs (1x DisplayPort 1.4a and 2x mini-DisplayPort 1.4a) is more relevant than the raw score difference. The performance parity means the WX 3100 can handle light gaming, but its driver optimizations favor professional ISV applications.

NVIDIA GeForce GTX 650 Ti Boost

The margin over the GTX 650 Ti Boost is 0.8%, with the rival scoring 9,659. This is the largest delta among the listed rivals, yet still under 1%. The GTX 650 Ti Boost is a desktop card from 2013, so the WX 3100’s modern feature set (Vulkan 1.3, DisplayPort 1.4a) provides better longevity, but raw performance is essentially identical.

Who Should Consider It

Benchmark results indicate the WX 3100 is best suited for 1080p professional workloads where driver certification matters more than raw speed. Users running entry-level CAD software, 2D drafting tools, or basic photo editing will find the 4 GB VRAM and 96.00 GB/s bandwidth sufficient for single-monitor setups. The card can drive up to three displays via its DisplayPort 1.4a outputs, making it viable for financial trading floors or multi-monitor office productivity. For 3D modeling with moderate polygon counts, the 512 shading units will deliver acceptable frame rates in viewport navigation, but final renders will be slow. Gamers should only consider this card for esports titles at low-to-medium settings, as the scores relative to GTX 960M suggest it is not built for high-refresh or high-detail gaming. Avoid this card for 4K workloads, VR, or any ray-traced content, as the memory bus and lack of RT cores are insurmountable barriers.

Benchmark Performance

The average benchmark score of 9,738 places the WX 3100 just above the 50th percentile of its rivals, but the deltas are remarkably tight. Against the Tesla C2070, the 0.2% lead (9,716 vs. 9,738) is meaningless in real-world terms; both cards would feel identical in most tasks. The 0.7% advantage over the WX 2100 (9,675) and GTX 960M (9,670) is similarly small, translating to roughly 60-70 points in raw scores. The largest gap is the 0.8% over the GTX 650 Ti Boost (9,659), which is still under 80 points. In isolation, the Geekbench OpenCL score of 7,404 and Vulkan score of 12,072 show that the card is notably better at Vulkan compute than OpenCL, which aligns with GCN’s strengths in async compute. The FP32 throughput of 1,248.3 GFLOPS matches FP16 at a 1:1 ratio, indicating no dedicated half-precision acceleration, which is typical for this architecture. The 46th percentile ranking confirms that the WX 3100 is a below-average GPU by overall performance, but within its immediate rival group, it is the top performer by a hair.

Power and Cooling

The WX 3100 has a TDP of 65 W, which is remarkably low for a workstation card, and it requires no external power connectors — it draws all power from the PCIe 3.0 x8 slot. The suggested PSU rating is 250 W, meaning even a modest office power supply is sufficient. The card is single-slot and measures 168 mm in length (6.6 inches) and 69 mm in height (2.7 inches), allowing it to fit into compact chassis. The lack of power connectors also simplifies cable management, and the low TDP ensures that a simple blower or passive cooler is adequate; the fact pack mentions no specific cooler type, but the thermal load is clearly minimal. The 14 nm process from GlobalFoundries contributes to this efficiency, with a transistor density of 21.4M per mm². For system integrators, this card is nearly plug-and-play, requiring only a 250 W PSU and a free PCIe x8 or x16 slot. The absence of a 6-pin or 8-pin connector makes it ideal for upgrading older pre-built systems with limited power delivery. The 65 W TDP also means no additional case fans are strictly necessary, though proper airflow is always recommended for sustained loads. The production status is end-of-life, so availability is limited to remaining stock or used markets, but the power characteristics remain a strong selling point for low-power workstations.
