AMD Radeon Pro WX 2100 vs NVIDIA GeForce 945M Comparison

Head-to-Head Benchmarks

The recorded database contains one shared benchmark between the AMD Radeon Pro WX 2100 and the NVIDIA GeForce 945M: Geekbench OpenCL. In that test, the AMD Radeon Pro WX 2100 scores 8,536, while the NVIDIA GeForce 945M scores 8,099. This translates to a 5.4% advantage for the AMD part, a meaningful but not overwhelming margin in compute workloads. The AMD card wins the only direct comparison on record, giving it a 1-0 head-to-head record.

Looking at the broader context, the AMD Radeon Pro WX 2100 sits at the 46th percentile among all GPUs in the database, with an average benchmark score of 9,653. Its nearest rivals are tightly clustered: the NVIDIA GeForce GTX 960M averages 9,645 (0.1% behind), the NVIDIA Quadro P4000 averages 9,665 (0.1% ahead), the NVIDIA Quadro K5000 averages 9,637 (0.2% behind), and the NVIDIA Tesla C2070 averages 9,716 (0.6% ahead). This places the WX 2100 in a narrow competitive band where a few points separate it from several established cards. The 5.4% lead over the 945M is actually larger than the delta between the WX 2100 and any of its four closest rivals, which suggests the 945M sits clearly below the WX 2100's performance tier.

The NVIDIA GeForce 945M, by contrast, holds the 42nd percentile among all GPUs, with an average benchmark score of 8,099. Its nearest rivals include the NVIDIA GRID K2 at 8,080 (0.2% behind), the AMD Radeon R9 M360 at 8,129 (0.4% ahead), the NVIDIA GeForce GTX 650 Ti Boost at 8,067 (0.4% behind), and the NVIDIA GeForce GTX 950M at 8,135 (0.4% ahead). These are all sub-0.5% deltas, meaning the 945M is effectively interchangeable with several mid-range mobile parts from the same era. The gap between the 945M's average score and the WX 2100's average score is substantial: 9,653 versus 8,099, a difference of about 19%. That is a much larger separation than anything seen within either card's immediate rival cluster.

The single OpenCL result tells a consistent story. The AMD card's 8,536 score in that test is 437 points higher than the NVIDIA card's 8,099. In percentage terms, the AMD part delivers roughly a 5.4% uplift in raw OpenCL compute throughput. For workloads that scale well with GPU compute, such as rendering, simulation, or data-parallel tasks, that margin is measurable and repeatable. The 945M does not close the gap in any other recorded benchmark, as no other head-to-head tests exist in the database.

Architecture Differences

The AMD Radeon Pro WX 2100 is built on the GCN 4.0 architecture, using the Lexa chip, and belongs to the Radeon Pro Polaris (WX x100) generation. It is manufactured on a 14 nm process at GlobalFoundries, with 2,200 million transistors packed into a 103 mm² die, yielding a transistor density of 21.4 million per square millimeter. The NVIDIA GeForce 945M, in contrast, uses the Maxwell architecture with the GM107 chip, part of the GeForce 900M generation. It is built on a 28 nm process at TSMC, with 1,870 million transistors on a 148 mm² die, giving a transistor density of 12.6 million per square millimeter. The process node difference is stark: 14 nm versus 28 nm, which explains the AMD part's higher density despite having more transistors on a smaller die.

The compute resources differ in configuration. The AMD card has 512 shading units, 32 texture mapping units, and 16 ROPs. The NVIDIA card has 640 shading units, 40 texture mapping units, and 16 ROPs. Even though the NVIDIA part has more shading units and TMUs, the AMD card achieves comparable or better output rates in several metrics. The AMD card's pixel rate is 19.50 GPixel/s, compared to 16.32 GPixel/s for the NVIDIA card. In texture rate, the AMD card reaches 39.01 GTexel/s, while the NVIDIA card reaches 40.80 GTexel/s, a narrow edge for NVIDIA. In FP32 compute, the AMD card delivers 1,248.3 GFLOPS, while the NVIDIA card delivers 1,305.6 GFLOPS, giving NVIDIA a small lead. The AMD card also supports FP16 at a 1:1 ratio (1,248.3 GFLOPS), while the NVIDIA card has no recorded FP16 capability.

Memory architecture is another major divergence. The AMD Radeon Pro WX 2100 uses 2 GB of GDDR5 on a 64-bit bus, with memory clocked at 1500 MHz (6 Gbps effective), producing 48.00 GB/s of bandwidth. The NVIDIA GeForce 945M uses 2 GB of DDR3 on a 128-bit bus, with memory clocked at 900 MHz (1800 Mbps effective), yielding 28.80 GB/s of bandwidth. The AMD card has 67% more memory bandwidth despite a narrower bus, a direct consequence of using GDDR5 instead of DDR3. The NVIDIA card's wider bus does not compensate for the slower memory type.

API support differs in DirectX and Vulkan versions. The AMD card supports DirectX 12 (12_0) and Vulkan 1.3, while the NVIDIA card supports DirectX 12 (11_0) and Vulkan 1.4. Both cards support OpenGL 4.6. The AMD card's DirectX 12 feature level is higher, while the NVIDIA card has a newer Vulkan version. The AMD card also has a different display output configuration: 1x DisplayPort 1.4a and 2x mini-DisplayPort 1.4a, whereas the NVIDIA card's display outputs are listed as portable device dependent, reflecting its mobile MXM form factor.

Specification Differences

The two cards differ across nearly every major specification category. The AMD Radeon Pro WX 2100 uses a 14 nm process, while the NVIDIA GeForce 945M uses 28 nm. The AMD chip (Lexa) contains 2,200 million transistors on a 103 mm² die, while the NVIDIA chip (GM107) contains 1,870 million transistors on a 148 mm² die. Transistor density is 21.4 million per square millimeter for AMD and 12.6 million per square millimeter for NVIDIA. The foundries differ: GlobalFoundries for AMD, TSMC for NVIDIA.

The AMD card is single-slot with no power connectors and a suggested PSU of 200 W. The NVIDIA card is an MXM module with no power connectors and no suggested PSU listed. The bus interface is PCIe 3.0 x8 for AMD and MXM-B (3.0) for NVIDIA. The AMD card has defined dimensions: 168 mm length (6.6 inches) and 69 mm height (2.7 inches). The NVIDIA card has no recorded dimensions. Display outputs are 1x DisplayPort 1.4a plus 2x mini-DisplayPort 1.4a for AMD, versus portable device dependent for NVIDIA. DirectX support is 12 (12_0) for AMD and 12 (11_0) for NVIDIA. Vulkan support is 1.3 for AMD and 1.4 for NVIDIA. Both support OpenGL 4.6. The AMD card launched on June 3, 2017, while the NVIDIA card launched on October 26, 2015. The AMD card's predecessor is Radeon Pro GCN and its successor is Radeon Pro Vega. The NVIDIA card's predecessor is GeForce 800M and its successor is GeForce 10 Mobile. The AMD card has a launch MSRP of 149 USD; no launch MSRP is recorded for the NVIDIA card.

The Verdict

The data points to a clear but not overwhelming winner in the AMD Radeon Pro WX 2100. It wins the only head-to-head benchmark on record, posting 8,536 versus 8,099 in Geekbench OpenCL, a 5.4% advantage. Its average benchmark score of 9,653 is roughly 19% higher than the 945M's 8,099, and it holds a higher percentile ranking (46th versus 42nd). The AMD card also delivers substantially more memory bandwidth (48.00 GB/s versus 28.80 GB/s), a higher boost clock (1219 MHz versus 1020 MHz), a smaller process node (14 nm versus 28 nm), and a much lower TDP (35 W versus 75 W). For compute-oriented workloads, the AMD card is the stronger choice on every measurable axis.

The NVIDIA GeForce 945M does have some advantages in the raw specification sheet. It offers more shading units (640 versus 512), more TMUs (40 versus 32), a wider memory bus (128-bit versus 64-bit), and slightly higher FP32 throughput (1,305.6 GFLOPS versus 1,248.3 GFLOPS). Its texture rate is also marginally higher (40.80 GTexel/s versus 39.01 GTexel/s). However, none of these advantages translate into a benchmark win. The 945M's higher shading unit count and FP32 output do not overcome its slower memory and lower boost clock in the recorded OpenCL test. The NVIDIA card's DX12 support stops at feature level 11_0, while the AMD card reaches 12_0, which could matter for newer DirectX 12 titles. The NVIDIA card does have a newer Vulkan version (1.4 versus 1.3).

For a buyer choosing between these two end-of-life parts, the AMD Radeon Pro WX 2100 is the better pick for general compute and display workloads. It wins the benchmark that matters, uses less power, has more memory bandwidth, and comes with a defined set of DisplayPort 1.4a outputs. The 945M, being an MXM mobile module with portable device dependent outputs, is less flexible for desktop use. The AMD card's 35 W TDP makes it far easier to cool and integrate, while the 945M's 75 W TDP demands more thermal headroom. The AMD card also has a recorded launch MSRP of 149 USD, whereas the NVIDIA card has no recorded launch price.

The NVIDIA GeForce 945M might appeal to someone who specifically needs its higher FP32 throughput or its wider memory bus, but the database shows no benchmark where that translates into a win. Its only recorded score is the OpenCL test it loses. The AMD card's nearest rivals are all within 0.6% of its average score, meaning it competes with much more capable parts like the Quadro P4000 and GTX 960M. The 945M's nearest rivals are similarly close to it, but they are all lower-tier parts. In this comparison, the AMD Radeon Pro WX 2100 is the superior product across the recorded measurements, and the data does not support choosing the 945M on performance grounds.
