Architecture Differences

The two GPUs come from different generations of AMD's Graphics Core Next architecture. The Vega 10 Mobile is built on GCN 5.0, using the Raven-M chip, while the Pro WX 4100 uses GCN 4.0 with the Baffin chip. Both are manufactured on a 14 nm process at GlobalFoundries, but the silicon differs notably. The Vega 10 Mobile integrates 4,940 million transistors on a 210 mm² die, whereas the Pro WX 4100 packs 3,000 million transistors on a smaller 123 mm² die. Consequently, the transistor density is slightly higher on the Pro WX 4100 at 24.4M per mm² versus 23.5M per mm² on the Vega 10 Mobile.

The Vega 10 Mobile belongs to the Vega IGP generation (Raven Ridge-M) and is an integrated part of a mobile processor. It has no dedicated memory, relying entirely on system RAM. The Pro WX 4100, from the Radeon Pro Polaris generation (WX x100), is a discrete card with 4 GB GDDR5 memory. Clock behavior also differs: the Vega 10 Mobile has a 300 MHz base clock boosting to 1,301 MHz, while the Pro WX 4100 runs at a higher 1,125 MHz base and 1,201 MHz boost. The Pro WX 4100's memory runs at 1,500 MHz (6 Gbps effective).

Compute capabilities diverge significantly. The Pro WX 4100 delivers 2.460 TFLOPS FP32 and the same 2.460 TFLOPS FP16 (1:1 ratio). The Vega 10 Mobile offers 1.665 TFLOPS FP32 and 3.331 TFLOPS FP16 (2:1 ratio). The Pro WX 4100 also has higher pixel and texture rates: 19.22 GPixel/s and 76.86 GTexel/s respectively, versus 10.41 GPixel/s and 52.04 GTexel/s on the Vega 10 Mobile.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the result is lopsided. The AMD Radeon Pro WX 4100 scores 17,642, while the AMD Radeon Vega 10 Mobile scores 6,476. That is a 63.3% deficit for the Vega 10 Mobile, making the Pro WX 4100 nearly three times faster in raw compute throughput. This aligns with the theoretical specifications: the Pro WX 4100 has 60% more shading units (1,024 vs. 640), double the ROPs (16 vs. 8), and 60% more TMUs (64 vs. 40). Its FP32 throughput of 2.460 TFLOPS is 47.7% higher than the Vega 10 Mobile's 1.665 TFLOPS.

However, the Pro WX 4100's advantage is not universal across all metrics. The Vega 10 Mobile actually has higher FP16 throughput at 3.331 TFLOPS versus the Pro WX 4100's 2.460 TFLOPS, thanks to its 2:1 FP16 ratio. This suggests the Vega 10 Mobile could be competitive in workloads specifically optimized for half-precision math, although no such benchmark appears in the data. The Pro WX 4100's dedicated GDDR5 memory with 96.00 GB/s bandwidth is a clear advantage over the Vega 10 Mobile's system-shared memory, which has dependent bandwidth.

In terms of relative standing, both GPUs sit at the 37th percentile among all GPUs, indicating they are mid-to-low performers in the broader market. The Vega 10 Mobile's nearest rival is the NVIDIA Quadro M5000M (6,481, delta -0.1%), a professional mobile GPU, while the Pro WX 4100's closest competitor is the AMD Radeon R7 M350 (6,327, delta 0.1%). The Pro WX 4100 also has additional benchmark data from PassMark, where it scores 3,699 in G3D, 1,475 in GPU Compute, and 646 in G2D, along with various DirectX tests (16 in DX10, 24 in DX11, 22 in DX12, 56 in DX9).

Specification Differences

The two GPUs differ across almost every measurable specification. The Vega 10 Mobile uses a 14 nm Raven-M chip on GCN 5.0 architecture, while the Pro WX 4100 uses a 14 nm Baffin chip on GCN 4.0. Transistor counts differ: 4,940 million for the Vega 10 Mobile versus 3,000 million for the Pro WX 4100. Die size is 210 mm² versus 123 mm². The Vega 10 Mobile has 640 shading units, 40 TMUs, and 8 ROPs; the Pro WX 4100 has 1,024 shading units, 64 TMUs, and 16 ROPs.

Clock speeds are configured differently. The Vega 10 Mobile has a 300 MHz base clock and 1,301 MHz boost, while the Pro WX 4100 has a 1,125 MHz base and 1,201 MHz boost. Memory is the most fundamental difference: the Vega 10 Mobile uses system-shared memory with no dedicated VRAM, while the Pro WX 4100 has 4 GB GDDR5 on a 128-bit bus with 96.00 GB/s bandwidth. The Vega 10 Mobile's memory clock is listed as "System Shared," while the Pro WX 4100 runs at 1,500 MHz (6 Gbps effective).

Power and physical specifications diverge sharply. The Vega 10 Mobile has a 10 W TDP, is an IGP with no slot width, and has no power connectors. The Pro WX 4100 has a 50 W TDP, is a single-slot card measuring 168 mm (6.6 inches) in length and 69 mm (2.7 inches) in height, and also requires no power connectors. The Pro WX 4100 has a suggested PSU of 250 W and uses a PCIe 3.0 x8 bus interface, while the Vega 10 Mobile is directly integrated. Display outputs differ: the Pro WX 4100 provides 4x mini-DisplayPort 1.4a, while the Vega 10 Mobile's outputs are "Portable Device Dependent."

API support shows a minor difference: the Vega 10 Mobile supports DirectX 12 (12_1), while the Pro WX 4100 supports DirectX 12 (12_0). Both support OpenGL 4.6 and Vulkan 1.3. Release dates differ by over two years, with the Pro WX 4100 launching in November 2016 and the Vega 10 Mobile in January 2019. The Pro WX 4100 has a launch MSRP of 399 USD.

The Verdict

The data paints a clear picture: the AMD Radeon Pro WX 4100 is the superior performer for compute-heavy tasks. Its Geekbench OpenCL score of 17,642 crushes the Vega 10 Mobile's 6,476 by 63.3%. The Pro WX 4100 offers higher FP32 throughput (2.460 vs. 1.665 TFLOPS), more shading units, double the ROPs, and dedicated GDDR5 memory with 96.00 GB/s bandwidth. For professional workloads that rely on these resources, the choice is unambiguous.

The AMD Radeon Vega 10 Mobile, however, should not be dismissed outright. Its 10 W TDP makes it suitable for power-constrained portable devices where integrated graphics are the only option. Its FP16 performance of 3.331 TFLOPS is actually higher than the Pro WX 4100's 2.460 TFLOPS, which could matter in specific half-precision workloads. It also supports the newer DirectX 12_1 feature level. But in the only head-to-head benchmark available, the Pro WX 4100 dominates.

Users who need a professional-grade discrete GPU with consistent memory bandwidth and higher compute throughput should choose the AMD Radeon Pro WX 4100. Users who require an integrated solution with minimal power draw and are willing to accept lower raw performance should consider the AMD Radeon Vega 10 Mobile. Both GPUs sit at the 37th percentile overall, so neither is a top-tier performer, but within this pairing, the Pro WX 4100 is the clear winner in every major performance metric.
