The Verdict

The benchmark data clearly favors the NVIDIA GeForce GTX 675MX in the single available head-to-head test, but the choice between these two cards depends heavily on the intended workload and platform. The NVIDIA card wins the Geekbench OpenCL test decisively, scoring 10,723 versus 8,536 for the AMD card, a 20.4% advantage. Its overall average benchmark score of 8,427 is actually lower than the AMD's 9,653, but this is because the NVIDIA card includes a Metal benchmark score of 6,131, which drags down its average; the AMD card has no Metal result.

For users who need maximum compute performance in OpenCL workloads, the NVIDIA GeForce GTX 675MX is the better pick, as it also offers 960 shading units and a massive 256-bit memory bus with 115.2 GB/s bandwidth. However, the AMD Radeon Pro WX 2100 is a professional workstation card with a much lower power draw of 35 W versus 100 W for the NVIDIA, and it supports newer API versions including Vulkan 1.3 and DirectX 12 (12_0) vs the NVIDIA's Vulkan 1.2.175 and DirectX 12 (11_0).

The AMD card also has a higher pixel rate (19.50 GPixel/s vs 13.08 GPixel/s) and a smaller, lighter form factor that is single-slot with no power connectors required. The NVIDIA card is an MXM module, which means it is designed for laptop replacement, not desktop installation. Therefore, the AMD card is the right choice for a professional desktop workstation with a focus on display output and low power, while the NVIDIA card is better for raw compute in a mobile or proprietary MXM context.

Head-to-Head Benchmarks

The only direct benchmark comparison available in the database is the Geekbench OpenCL test, and the NVIDIA GeForce GTX 675MX wins it by a significant margin. The NVIDIA card scores 10,723, while the AMD Radeon Pro WX 2100 scores 8,536. This is a 20.4% difference, making the NVIDIA card clearly faster in this specific compute workload.

This result is consistent with the hardware specifications. The NVIDIA card has 960 shading units and 80 texture mapping units, compared to 512 shading units and 32 TMUs for the AMD card. The NVIDIA card also has a memory bandwidth of 115.2 GB/s from its 256-bit bus, versus 48.00 GB/s from a 64-bit bus on the AMD card. These are strong indicators of why the NVIDIA card excels in OpenCL compute tasks, as it can feed data to its shaders much faster.

However, the AMD card is not without its own strengths. Its pixel rate of 19.50 GPixel/s is 49% higher than the NVIDIA's 13.08 GPixel/s, meaning it can fill the screen with rasterized pixels faster. Its texture rate of 39.01 GTexel/s is lower than the NVIDIA's 52.32 GTexel/s, but the pixel rate advantage suggests that the AMD card may be better suited for certain graphics render paths that are pixel-bound.

In terms of overall average benchmark scores, the AMD card actually leads with 9,653 versus the NVIDIA's 8,427. This is because the AMD card has both an OpenCL score (8,536) and a Vulkan score (10,770), while the NVIDIA card has an OpenCL score (10,723) and a Metal score (6,131). The Vulkan score for the AMD is nearly as high as the NVIDIA's OpenCL score, and the Metal score for the NVIDIA is notably low, which pulls its average down.

Specification Differences

Architecture Differences

The AMD Radeon Pro WX 2100 is built on the GCN 4.0 architecture with the Lexa chip, part of the Radeon Pro Polaris generation. It uses a 14 nm process at GlobalFoundries, with 2,200 million transistors on a 103 mm² die, giving a transistor density of 21.4M per mm².

The NVIDIA GeForce GTX 675MX is built on the Kepler architecture with the GK104 chip, part of the GeForce 600M generation. It uses a 28 nm process at TSMC, with 3,540 million transistors on a 294 mm² die, giving a transistor density of 12.0M per mm².

These architectural differences are stark. The AMD card uses a newer, denser process, which is why it can achieve a much lower TDP of 35 W. The NVIDIA card has more transistors (3,540 million vs 2,200 million) but on a much older process, resulting in a higher TDP of 100 W.

The AMD card has a smaller die (103 mm² vs 294 mm²) but achieves a higher pixel rate (19.50 GPixel/s vs 13.08 GPixel/s). The NVIDIA card has a higher texture rate (52.32 GTexel/s vs 39.01 GTexel/s) and higher FP32 (1,255.7 GFLOPS vs 1,248.3 GFLOPS).

The AMD card supports FP16 at the same rate as FP32 (1:1), which is a feature the NVIDIA card lacks entirely. The AMD card also supports newer API versions, including Vulkan 1.3 and DirectX 12 (12_0), while the NVIDIA card is limited to Vulkan 1.2.175 and DirectX 12 (11_0).

Where Each One Wins

The NVIDIA GeForce GTX 675MX wins in raw compute performance, as demonstrated by its 20.4% lead in the Geekbench OpenCL test. This is supported by its higher shading unit count (960 vs 512), higher TMU count (80 vs 32), and vastly higher memory bandwidth (115.2 GB/s vs 48.00 GB/s). The NVIDIA card is the better choice for OpenCL-heavy compute workloads, especially if the system can accommodate an MXM module.

The AMD Radeon Pro WX 2100 wins in several other areas. It has a higher pixel rate (19.50 GPixel/s vs 13.08 GPixel/s), which can be advantageous for specific rendering tasks. It also has a significantly lower TDP of 35 W versus 100 W, making it far more power-efficient. The AMD card is a single-slot, PCIe 3.0 x8 card with dedicated display outputs (1x DisplayPort 1.4a and 2x mini-DisplayPort 1.4a), making it easy to install in a desktop workstation.

The AMD card also supports newer APIs, including Vulkan 1.3 and DirectX 12 (12_0), which may offer better compatibility with modern applications. Its FP16 support (1,248.3 GFLOPS, 1:1) is another advantage for workloads that can use half-precision math.

In terms of overall average benchmark score, the AMD card leads with 9,653 versus the NVIDIA's 8,427, driven by its strong Vulkan score of 10,770. However, this average is skewed by the NVIDIA's low Metal score of 6,131, which is not directly comparable to the other tests. For a professional workstation with low power requirements and display output needs, the AMD card is the winner. For maximum compute performance in an MXM-based system, the NVIDIA card is the winner.
