AMD Radeon Pro WX 3100 vs NVIDIA GeForce GTX 750 Comparison

The AMD Radeon Pro WX 3100 and NVIDIA GeForce GTX 750 are both end-of-life, single-slot graphics cards aimed at different segments, yet benchmark data shows they land in a similar performance class overall. The Radeon Pro WX 3100 sits at the 41st percentile of all GPUs, while the GTX 750 is just behind at the 40th percentile. Despite the Pro WX 3100 having a higher average benchmark score of 7,580 compared to the GTX 750's 7,222, the head-to-head results tell a different story: the NVIDIA card wins both shared tests, with a decisive 21.3% lead in OpenCL and a narrower 3.1% edge in Vulkan. This creates an interesting dynamic where the newer professional card loses on raw compute tests to an older consumer card, though the architectural approaches differ significantly.

Where Each One Wins

The NVIDIA GeForce GTX 750 claims victory in every benchmark where both cards were tested head-to-head. Its most dominant result comes in Geekbench OpenCL, where it scores 9,315 against the Radeon Pro WX 3100's 7,333—a substantial 21.3% advantage. This suggests the GTX 750 handles general-purpose compute workloads with significantly more efficiency, likely benefiting from its higher base clock of 1020 MHz compared to the Radeon's 925 MHz. The GTX 750 also wins the Vulkan test, posting 8,078 versus 7,827, though the 3.1% margin is much closer and indicates the Radeon Pro WX 3100 is more competitive in modern graphics APIs.

The AMD Radeon Pro WX 3100, despite losing both head-to-head matchups, does not go entirely without merits. Its average benchmark score of 7,580 exceeds the GTX 750's 7,222 by roughly 5%, and it holds a higher percentile ranking at 41 versus 40. The Radeon also demonstrates better positioning among its nearest rivals: it sits within 1.4% of the GeForce GTX 1650 and just 0.3% behind the Radeon R7 250, whereas the GTX 750's closest competitor is the Radeon Vega 8 Mobile at 0.3% ahead. For users prioritizing Vulkan performance, the Radeon's 7,827 score is only 251 points below the GTX 750's 8,078, making the gap nearly negligible in real-world terms.

The data suggests a clear split: the GTX 750 excels in raw OpenCL compute throughput, while the Radeon Pro WX 3100 offers a more balanced profile with stronger average scores across all benchmarks. The GTX 750's 9,315 OpenCL result is its standout achievement, ranking it well above its 40th percentile overall position, whereas the Radeon Pro WX 3100's Vulkan score of 7,827 is notably closer to the NVIDIA card than its OpenCL result, indicating architectural strengths that favor newer API workloads.

Architecture Differences

The two cards represent fundamentally different design philosophies from their respective manufacturers. The AMD Radeon Pro WX 3100 uses the Lexa chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 2,200 million transistors into a 103 mm² die, achieving a transistor density of 21.4 million per square millimeter. In contrast, the NVIDIA GeForce GTX 750 employs the GM107 chip based on Maxwell architecture, manufactured on a 28 nm process at TSMC. This older process node results in 1,870 million transistors spread across a larger 148 mm² die, yielding a much lower density of 12.6 million per square millimeter.

Memory configurations differ notably between the two. The Radeon Pro WX 3100 comes with 4 GB of GDDR5 memory on a 128-bit bus, delivering 96.00 GB/s of bandwidth. The GTX 750 is more limited with just 1024 MB (1 GB) of GDDR5 on the same 128-bit bus, resulting in 80.19 GB/s bandwidth—roughly 16.5% less. Both cards share identical compute core counts: 512 shading units, 32 texture mapping units, and 16 raster output pipelines. However, clock speeds diverge, with the GTX 750 running at 1020 MHz base and 1085 MHz boost, while the Radeon Pro WX 3100 operates at 925 MHz base and 1219 MHz boost. The Radeon's higher boost clock partially compensates for its lower base frequency.

Feature support reveals generational differences. The Radeon Pro WX 3100 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, while the GTX 750 supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The newer Vulkan version on the NVIDIA card is notable given its older architecture. The Radeon Pro WX 3100 also offers FP16 compute at 1,248.3 GFLOPS (1:1 ratio with FP32), whereas the GTX 750 has no listed FP16 capability. Display outputs differ as well: the Radeon provides 1x DisplayPort 1.4a and 2x mini-DisplayPort 1.4a, while the GTX 750 offers 2x DVI and 1x mini-HDMI 1.4a, reflecting their different target markets.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the most lopsided result in this comparison. The NVIDIA GeForce GTX 750 scores 9,315, which is 21.3% higher than the AMD Radeon Pro WX 3100's 7,333. This margin is significant enough to be considered a decisive victory for the NVIDIA card in compute-heavy workloads. The GTX 750's advantage likely stems from its higher base clock speed of 1020 MHz versus the Radeon's 925 MHz, combined with Maxwell's efficient compute architecture. The Radeon's higher boost clock of 1219 MHz cannot overcome this deficit, suggesting the NVIDIA card sustains its peak performance more effectively under load.

The Vulkan benchmark shows a much tighter contest. The GTX 750 wins again with 8,078 points, but the Radeon Pro WX 3100 trails by only 251 points, a 3.1% gap. This result indicates that when both cards engage modern graphics APIs, the Radeon Pro WX 3100 becomes far more competitive. The Radeon's support for Vulkan 1.3 and its GCN 4.0 architecture appear to narrow the performance gap substantially. Notably, the Radeon Pro WX 3100's Vulkan score of 7,827 is actually higher than its OpenCL score of 7,333, suggesting the architecture performs better with graphics-oriented workloads than with general compute.

Looking at broader benchmark context, the Radeon Pro WX 3100's average score of 7,580 places it 0.3% above the Radeon R7 250 and 1.4% above the GeForce GTX 1650, while sitting 1.2% below the Radeon 540. The GTX 750's average of 7,222 puts it 0.3% behind the Radeon Vega 8 Mobile and 0.9% ahead of the GeForce GTX 970. These figures show both cards operating in a similar league, but the GTX 750's OpenCL dominance is the single most defining benchmark result in this comparison. The Radeon Pro WX 3100, despite losing both head-to-head tests, achieves a higher average score across its benchmark suite, indicating that its Vulkan performance helps offset the OpenCL deficit.

Specification Differences

The most striking specification gap is memory capacity: the Radeon Pro WX 3100 offers 4 GB of GDDR5, while the GTX 750 is limited to 1024 MB. This fourfold difference could impact texture-heavy workloads and larger datasets. Memory bandwidth also favors the AMD card at 96.00 GB/s versus 80.19 GB/s, a 19.7% advantage. Process technology shows the Radeon Pro WX 3100 on 14 nm from GlobalFoundries, while the GTX 750 uses 28 nm from TSMC—a full node generation apart. Transistor counts differ as well, with the Radeon at 2,200 million and the GTX 750 at 1,870 million, though the Radeon achieves this in a smaller 103 mm² die compared to 148 mm².

Clock specifications reveal an interesting trade-off. The GTX 750 has a higher base clock at 1020 MHz versus 925 MHz, but the Radeon Pro WX 3100 boosts higher at 1219 MHz versus 1085 MHz. Memory clocks follow a similar pattern: the Radeon runs at 1500 MHz (6 Gbps effective), while the GTX 750 runs at 1253 MHz (5 Gbps effective). Power consumption favors the GTX 750 at 55 W TDP, while the Radeon Pro WX 3100 draws 65 W—both well within the 250 W suggested PSU requirement. The bus interface differs, with the Radeon using PCIe 3.0 x8 and the GTX 750 using PCIe 3.0 x16.

Pixel and texture fill rates reflect the clock differences. The Radeon Pro WX 3100 achieves 19.50 GPixel/s and 39.01 GTexel/s, while the GTX 750 manages 17.36 GPixel/s and 34.72 GTexel/s. FP32 performance also favors the AMD card at 1,248.3 GFLOPS versus 1,111.0 GFLOPS. Physical dimensions show the GTX 750 is shorter at 145 mm (5.7 inches) compared to the Radeon's 168 mm (6.6 inches), while the Radeon has a listed height of 69 mm (2.7 inches). The GTX 750's launch MSRP was 119 USD, and the Radeon Pro WX 3100's was 199 USD.
