AMD Radeon Pro WX 4100 vs AMD Radeon Vega 8 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Radeon Vega 8 Mobile and the AMD Radeon Pro WX 4100. In the two shared benchmark tests, the Pro WX 4100 wins both outright. The first test, Geekbench OpenCL, shows the Pro WX 4100 scoring 17,642 against the Vega 8 Mobile’s 7,435. That translates to a delta of -57.9% for the Vega 8 Mobile, meaning the Pro WX 4100 more than doubles the integrated part’s score. The second test, Geekbench Vulkan, shows a similar pattern: the Pro WX 4100 posts 18,703 while the Vega 8 Mobile manages 6,970, a delta of -62.7%. In both cases, the margin is substantial and consistent, indicating that the discrete card’s advantage is not limited to one API or workload type.

It is notably the Vega 8 Mobile’s average benchmark score across all recorded tests is 7,203, while the Pro WX 4100’s average is 6,330. This apparent contradiction stems from the fact that the Pro WX 4100 has a much wider set of benchmark results in the database, including several Passmark tests where scores are low (for example, Passmark DirectX 10 at 16, DirectX 11 at 24, DirectX 12 at 22, and DirectX 9 at 56). Those low-scoring legacy tests drag down its average despite its strong Geekbench showing. The Vega 8 Mobile, by contrast, only has two Geekbench results in the database, both of which are moderate. Therefore, the head-to-head comparison is best understood through the two directly comparable tests, where the Pro WX 4100 leads by a wide margin.

The nearest rivals for each part further contextualize these numbers. The Vega 8 Mobile sits at the 39th percentile of all GPUs, with its closest competitor being the NVIDIA GeForce GTX 750, which scores 7,222, a delta of -0.3%. That means the Vega 8 Mobile is essentially on par with a GTX 750, within noise. Other nearby rivals include the GTX 560 SE at 7,171 (0.4% ahead), the Intel Iris Pro Graphics P580 at 7,170 (0.5% ahead), and the GTX 970 at 7,157 (0.6% ahead). These are all extremely tight margins, suggesting the Vega 8 Mobile occupies a narrow performance band around the 7,200 mark. The Pro WX 4100, meanwhile, sits at the 37th percentile, slightly lower than the Vega 8 Mobile, with its nearest rival being the AMD Radeon R7 M350 at 6,327 (0.1% ahead), the NVIDIA Quadro K620 at 6,282 (0.8% ahead), and the NVIDIA GeForce GTX 460 SE and GTX 580M, both at 6,389 (-0.9% for both). The Pro WX 4100’s average is pulled down by its Passmark results, but its Geekbench scores are far above anything the Vega 8 Mobile can produce.

Where Each One Wins

The AMD Radeon Pro WX 4100 wins in every directly comparable benchmark. In Geekbench OpenCL, its score of 17,642 versus 7,435 represents a 57.9% advantage. In Geekbench Vulkan, its score of 18,703 versus 6,970 represents a 62.7% advantage. These are not marginal differences; they are large enough to classify the Pro WX 4100 as a meaningfully faster GPU for compute-oriented tasks, particularly those that leverage OpenCL or Vulkan. The Pro WX 4100 also shows strength in its additional benchmark suite, such as Passmark G3D at 3,699 and Passmark GPU Compute at 1,475, though those tests have no direct counterpart in the Vega 8 Mobile’s record.

The Vega 8 Mobile, by contrast, has no benchmark wins in the head-to-head data. Its two recorded scores, 7,435 in OpenCL and 6,970 in Vulkan, are both below the Pro WX 4100’s corresponding scores. However, the Vega 8 Mobile does have some qualitative advantages that are not captured by raw compute scores. It is an integrated graphics processor (IGP) with a 25 W TDP, meaning it draws far less power than the Pro WX 4100’s 50 W TDP. It also uses system-shared memory, which eliminates the need for dedicated VRAM allocation, and it has no power connectors, making it suitable for compact or portable devices. The Pro WX 4100, in contrast, requires a PCIe 3.0 x8 slot and is a single-slot card measuring 168 mm in length.

For use cases that prioritize raw compute throughput, the Pro WX 4100 is the clear winner. For use cases that prioritize low power draw, minimal physical footprint, and integration into a portable device, the Vega 8 Mobile has structural advantages. The data does not show any scenario where the Vega 8 Mobile outperforms the Pro WX 4100 in a benchmark, so any “win” for the Vega 8 Mobile would be based on system-level considerations rather than GPU performance.

Architecture Differences

The two GPUs come from different generations of AMD’s Graphics Core Next (GCN) architecture. The Vega 8 Mobile uses GCN 5.0, built on the Raven-M chip, and belongs to the Vega IGP generation (Raven Ridge-M). The Pro WX 4100 uses GCN 4.0, built on the Baffin chip, and belongs to the Radeon Pro Polaris generation (WX x100). Both are fabricated on a 14 nm process at GlobalFoundries, so the manufacturing node is identical. However, the transistor counts and die sizes differ significantly. The Vega 8 Mobile has 4,940 million transistors on a 210 mm² die, giving a transistor density of 23.5 million per mm². The Pro WX 4100 has 3,000 million transistors on a 123 mm² die, giving a higher density of 24.4 million per mm². Despite having fewer transistors, the Pro WX 4100’s smaller die and more focused design likely contribute to its higher clock speeds and dedicated memory.

The Vega 8 Mobile has 512 shading units, 32 texture mapping units (TMUs), and 8 raster output units (ROPs). The Pro WX 4100 doubles those counts: 1,024 shading units, 64 TMUs, and 16 ROPs. This doubling is directly reflected in the pixel and texture rates. The Vega 8 Mobile achieves a pixel rate of 8.808 GPixel/s and a texture rate of 35.23 GTexel/s. The Pro WX 4100 achieves 19.22 GPixel/s and 76.86 GTexel/s, roughly 2.2 times higher in both cases. The FP32 compute throughput follows the same pattern: the Vega 8 Mobile delivers 1,127.4 GFLOPS, while the Pro WX 4100 delivers 2.460 TFLOPS. The FP16 numbers are also telling: the Vega 8 Mobile offers 2.255 TFLOPS at a 2:1 ratio, while the Pro WX 4100 offers 2.460 TFLOPS at a 1:1 ratio, meaning the Pro WX 4100 does not sacrifice FP16 performance.

Clock speeds differ substantially. The Vega 8 Mobile has a base clock of 300 MHz and a boost clock of 1101 MHz. The Pro WX 4100 has a base clock of 1125 MHz and a boost clock of 1201 MHz. The Pro WX 4100’s base clock is nearly four times higher than the Vega 8 Mobile’s base clock, which explains much of the performance gap despite the same process node. Memory configurations are also fundamentally different. The Vega 8 Mobile uses system-shared memory, with bandwidth labeled as “System Dependent.” The Pro WX 4100 has 4 GB of GDDR5 memory on a 128-bit bus, delivering 96.00 GB/s of bandwidth. Memory clock is 1500 MHz (6 Gbps effective) for the Pro WX 4100, while the Vega 8 Mobile’s memory clock is tied to the system.

The Pro WX 4100 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The Vega 8 Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The DirectX version difference is minor but noteworthy: the Vega 8 Mobile supports a higher feature level (12_1), which could matter for certain modern gaming or compute features. The Pro WX 4100’s display outputs are four mini-DisplayPort 1.4a connectors, while the Vega 8 Mobile’s display outputs are “Portable Device Dependent,” reflecting its IGP nature. The Pro WX 4100 is a single-slot card with no power connectors and a suggested PSU of 250 W. The Vega 8 Mobile has no power connectors either, but its TDP is 25 W versus the Pro WX 4100’s 50 W.

The Verdict

From the recorded data, the AMD Radeon Pro WX 4100 is the superior GPU in raw performance. In the two head-to-head benchmarks, it wins both by margins of 57.9% and 62.7%. Its doubled shading units, TMUs, and ROPs, combined with dedicated GDDR5 memory and higher clocks, give it a clear compute advantage. Any workload that is GPU-bound, particularly OpenCL or Vulkan compute, will run significantly faster on the Pro WX 4100. The Pro WX 4100 also has a wider benchmark record in the database, including Passmark results, which show reasonable performance in G3D (3,699) and GPU Compute (1,475), though its legacy DirectX 9/10/11/12 scores are low.

The AMD Radeon Vega 8 Mobile is not without its merits, but they are not performance merits. Its 25 W TDP makes it far more power-efficient than the Pro WX 4100’s 50 W TDP. It requires no dedicated slot, no external power, and no separate memory, as it uses system-shared memory. For a portable device where space and power are at a premium, the Vega 8 Mobile is a sensible choice, and its benchmark scores are respectable for an IGP, sitting within 0.6% of several desktop and mobile discrete GPUs from NVIDIA. However, the data does not show any workload where the Vega 8 Mobile beats the Pro WX 4100.

Choosing between them depends entirely on the system context. If the GPU must be a discrete card in a desktop or workstation with a PCIe slot, the Pro WX 4100 is the obvious pick, delivering more than double the compute throughput. If the GPU is integrated into a laptop or other portable device, the Vega 8 Mobile is the only one of the two that fits, since the Pro WX 4100 is a standalone card. The Pro WX 4100’s launch MSRP was 399 USD, which can be stated as a historical reference, but no price comparison or value analysis is provided in the data. The Verdict, strictly from the numbers, is that the Pro WX 4100 wins on performance, while the Vega 8 Mobile wins on integration and power efficiency.
