AMD Radeon Pro WX 4100 vs NVIDIA GeForce GTX 770M Comparison

The AMD Radeon Pro WX 4100 and NVIDIA GeForce GTX 770M represent two very different eras of GPU design, and the benchmark data reflects that gap clearly. The WX 4100 is a modern professional workstation card built on a 14 nm process, while the GTX 770M is an older mobile gaming chip from the 28 nm era. Across the two benchmarks where both cards have scores, the AMD part wins both decisively, but the comparison is more nuanced than a simple sweep suggests.

Head-to-Head Benchmarks

The most dramatic disparity appears in the Geekbench Metal test. The AMD Radeon Pro WX 4100 scores 21,018 points, while the NVIDIA GeForce GTX 770M manages only 3,448 points. That is a 509.6% delta in favor of AMD — a six-fold advantage that shows how far GPU compute performance has come between generations. This is not a close contest by any measure; the WX 4100 obliterates the older chip in this API.

The Geekbench OpenCL test tells a similar story, though with a smaller margin. The WX 4100 posts 17,642 points against the GTX 770M's 8,552 points, a 106.3% delta. While still a clear win for AMD, this result shows the GTX 770M is comparatively stronger in OpenCL than in Metal — likely reflecting the NVIDIA architecture's compute strengths relative to its graphics capabilities. Still, the WX 4100 more than doubles the older card's score.

There are no benchmark wins for the GTX 770M in the head-to-head data. The WX 4100 takes both tests, giving it a 2-0 record in direct comparisons. Looking at broader averages, the AMD card holds a 6,330 average benchmark score across all its tested workloads, versus 6,000 for the GTX 770M. That 5.5% overall advantage is far smaller than the individual head-to-head deltas suggest, because the GTX 770M's average is pulled by its stronger OpenCL showing relative to other tests the WX 4100 runs.

Architecture Differences

The two GPUs come from completely different design philosophies. The AMD Radeon Pro WX 4100 uses the Baffin chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 3,000 million transistors into a 123 mm² die, giving it a transistor density of 24.4 million per square millimeter. The NVIDIA GeForce GTX 770M, by contrast, uses the GK106 chip on the older Kepler architecture, built on a 28 nm process at TSMC. It contains 2,540 million transistors spread across a much larger 221 mm² die, resulting in only 11.5 million transistors per square millimeter.

The clock speeds reflect these architectural differences. The WX 4100 runs at a 1,125 MHz base clock with a 1,201 MHz boost, while the GTX 770M operates at just 706 MHz base and 797 MHz boost. The AMD card's higher clocks are partly enabled by the more efficient 14 nm process, but the architecture itself is also designed differently. The WX 4100 features 1,024 shading units, 64 texture mapping units, and 16 ROPs. The GTX 770M has 960 shading units, 80 TMUs, and 24 ROPs — a configuration that favors texture and pixel throughput over raw shader count.

Memory configurations also diverge significantly. The WX 4100 uses 4 GB of GDDR5 on a 128-bit bus, delivering 96.00 GB/s of bandwidth. The GTX 770M has 3 GB of GDDR5 on a wider 192-bit bus, achieving 96.19 GB/s. The bandwidth figures are nearly identical, but the AMD card does it with a narrower bus and faster effective memory speed (6 Gbps versus 4 Gbps). The WX 4100 also offers 2.460 TFLOPS of FP32 compute and 2.460 TFLOPS of FP16 (1:1 ratio), while the GTX 770M delivers only 1.530 TFLOPS of FP32 and has no FP16 capability listed.

The form factors could not be more different. The WX 4100 is a single-slot PCIe 3.0 x8 card measuring 168 mm in length, with four mini-DisplayPort 1.4a outputs and no power connector required — it draws just 50 W. The GTX 770M is an MXM Module using the MXM-B (3.0) interface, with display outputs that are "Portable Device Dependent," meaning it is designed to be soldered into laptops. Its 75 W TDP is higher than the AMD card despite the older process node.

Where Each One Wins

The AMD Radeon Pro WX 4100 wins decisively in compute-heavy workloads, as evidenced by its 509.6% advantage in Metal and 106.3% lead in OpenCL. Its 2.460 TFLOPS of FP32 performance, paired with 1:1 FP16 support, makes it suitable for professional applications that leverage GPU compute — think rendering, simulation, or data processing tasks that can use the high throughput. The 4 GB of VRAM on a 128-bit bus is adequate for workstation-class workloads at moderate resolutions, and the single-slot form factor with four display outputs positions it as a multi-monitor professional solution.

The NVIDIA GeForce GTX 770M has no benchmark wins in this comparison, but its architecture still has strengths worth noting. The 80 TMUs and 24 ROPs give it a higher texture fill rate potential relative to its shading units, which historically benefits rasterization-heavy workloads like gaming at lower resolutions. Its 96.19 GB/s memory bandwidth matches the AMD card, so memory-bound tasks should perform similarly. The MXM form factor means it is not a direct upgrade path for desktop users, but in its native laptop environment, it offers a 3 GB frame buffer that suits 1080p gaming of its era.

The GTX 770M's 75 W TDP is higher than the WX 4100's 50 W, but in a laptop context that power budget is more constrained by thermal headroom than raw wattage. The NVIDIA card's Kepler architecture supports DirectX 12 (11_0) and Vulkan 1.2.175, while the AMD card supports DirectX 12 (12_0) and Vulkan 1.3 — the newer API versions on the WX 4100 reflect its later release date of November 2016 versus May 2013 for the GTX 770M.

The Verdict

From the data, the AMD Radeon Pro WX 4100 is the clear choice for anyone who needs compute performance. It doubles the GTX 770M's OpenCL score and multiplies its Metal score by over six times. The 14 nm process, higher clocks, and doubled FP32 throughput make it a fundamentally more capable compute device. Its 4 GB of VRAM matches or exceeds the GTX 770M's 3 GB, and its 96.00 GB/s bandwidth is effectively identical. For professional workloads that use Metal or OpenCL, the WX 4100 is vastly superior.

The NVIDIA GeForce GTX 770M makes sense only if you are constrained to the MXM laptop form factor. There is no desktop equivalent in this comparison, and the data shows it is outclassed in every head-to-head benchmark. Its 35th percentile ranking among all GPUs versus the WX 4100's 37th percentile confirms they are close in the broader landscape, but the GTX 770M's average benchmark score of 6,000 trails the AMD card's 6,330. The GTX 770M's nearest rival is the AMD Radeon RX 6400 at a 0% delta, while the WX 4100 sits just 0.1% ahead of the AMD Radeon R7 M350 — both cards are mid-pack performers.

For a desktop workstation upgrade or a new professional build, the WX 4100 is the only rational pick. For a legacy laptop that requires the GTX 770M's specific MXM interface, it remains functional but shows its age. The 2-0 win record for AMD in head-to-head tests, combined with the massive deltas in both compute APIs, leaves no ambiguity about which GPU is faster.
