AMD Radeon Pro WX 3100 vs AMD Radeon Vega 8 Comparison

Head-to-Head Benchmarks

The head-to-head comparison between the AMD Radeon Vega 8 and the AMD Radeon Pro WX 3100 covers two shared benchmark tests, and the Vega 8 wins both. In the Geekbench OpenCL test, the Vega 8 scores 8,822 against 7,333 for the Pro WX 3100, a 20.3% advantage. This is a substantial gap, placing the integrated part clearly ahead of the discrete professional card in raw compute throughput under OpenCL. The Vulkan result narrows the margin considerably: the Vega 8 posts 8,134 while the Pro WX 3100 reaches 7,827, giving the Vega 8 a 3.9% lead. While the Vega 8 wins both tests, the Vulkan result shows the Pro WX 3100 is much closer when the workload uses that API.

Looking at the broader database averages, the Vega 8 has an average benchmark score of 9,221, which places it in the 45th percentile among all GPUs. The Pro WX 3100 averages 7,580, sitting in the 41st percentile. The difference in average scores is 21.7% in favor of the Vega 8, consistent with the OpenCL head-to-head margin. The Pro WX 3100's nearest rivals in the database include the AMD Radeon R7 250 at 7,557 (0.3% behind) and the Intel Arc A310 at 7,550 (0.4% behind). The Vega 8, meanwhile, sits within 0.6% of the NVIDIA GeForce GTX 960 and within 0.8% of the GeForce GTX 465, which are both discrete desktop cards from NVIDIA's older generations. This contextualizes the Vega 8's performance: it is not merely ahead of the Pro WX 3100, it is competing with dedicated graphics cards from a higher performance tier.

The Vega 8's average score of 9,221 is within 0.1% of the AMD Radeon 890M, a much newer integrated GPU. That near-parity is notable given the age difference and the fact that the Vega 8 is an end-of-life product. The Pro WX 3100, by contrast, sits within 1.4% of the NVIDIA GeForce GTX 1650, another dedicated card, but from the opposite direction: the Pro WX 3100 is slightly ahead of that rival. The data shows the Vega 8 as the stronger performer in every direct comparison available.

Where Each One Wins

The AMD Radeon Vega 8 wins in all recorded head-to-head benchmarks, but the size of the win depends heavily on the API. In OpenCL, the Vega 8 is 20.3% ahead of the Pro WX 3100. That is a decisive margin, suggesting workloads that leverage OpenCL compute will see a clear benefit from the Vega 8. The Vega 8 also has a higher average benchmark score overall, at 9,221 versus 7,580, so across mixed workloads it maintains the advantage.

The AMD Radeon Pro WX 3100 does not win any recorded benchmark against the Vega 8, but it has structural advantages that matter outside raw score comparisons. Its memory system is dedicated: 4 GB of GDDR5 on a 128-bit bus with 96.00 GB/s of bandwidth. This is a fixed allocation, not dependent on the host system. The Vega 8 uses system shared memory, with bandwidth described as system dependent. In real-world use, the Pro WX 3100's memory performance will be consistent regardless of the host platform, whereas the Vega 8's memory throughput will vary based on the system's RAM configuration. The Pro WX 3100 also has a higher pixel rate at 19.50 GPixel/s versus 8.800 GPixel/s, and a higher texture rate at 39.01 GTexel/s versus 35.20 GTexel/s. For fill-rate-bound tasks, the Pro WX 3100 is the stronger choice even if its compute scores are lower.

The Pro WX 3100 also carries professional workstation credentials. Its display outputs include 1x DisplayPort 1.4a and 2x mini-DisplayPort 1.4a, whereas the Vega 8's outputs are motherboard dependent. The Vega 8 is an integrated graphics processor, so it has no dedicated video outputs or power connectors. The Pro WX 3100 is a single-slot card with no power connectors but has a suggested power supply of 250 W. For systems where a discrete card with fixed outputs is required, the Pro WX 3100 is the only option of the two.

Architecture Differences

The two GPUs come from different generations of AMD's Graphics Core Next architecture. The Vega 8 is built on GCN 5.0, using the Raven chip, and belongs to the Vega IGP generation from the Raven Ridge family. The Pro WX 3100 uses GCN 4.0, built on the Lexa chip, and belongs to the Radeon Pro Polaris generation. Both are fabricated on a 14 nm process at GlobalFoundries, but the chips differ significantly in size and complexity. The Raven chip has 4,940 million transistors on a 210 mm² die, giving a transistor density of 23.5M per mm². The Lexa chip has 2,200 million transistors on a 103 mm² die, with a density of 21.4M per mm². The Vega 8's chip is more than twice the die area and over twice the transistor count of the Pro WX 3100's chip.

Both GPUs have 512 shading units and 32 texture mapping units. The Vega 8 has 8 ROPs, while the Pro WX 3100 has 16 ROPs. That doubling of ROPs explains the Pro WX 3100's higher pixel rate. The Vega 8's FP32 throughput is 1,126.4 GFLOPS, while the Pro WX 3100 reaches 1,248.3 GFLOPS. The Vega 8 has a significantly higher FP16 figure at 2.253 TFLOPS, but that is achieved with a 2:1 ratio, meaning it processes half-precision at twice the rate of single-precision. The Pro WX 3100's FP16 rate is 1,248.3 GFLOPS at a 1:1 ratio, so it does not gain any advantage from half-precision workloads.

Memory architecture is a major divergence. The Vega 8 shares system memory with the CPU, with no dedicated VRAM, no fixed bus width, and no independent bandwidth figure. The Pro WX 3100 uses 4 GB of GDDR5 on a 128-bit bus with 96.00 GB/s of bandwidth. Clock behavior also differs. The Vega 8 has a base clock of 300 MHz and a boost clock of 1100 MHz. The Pro WX 3100 has a base clock of 925 MHz and a boost clock of 1219 MHz, with memory clocked at 1500 MHz, translated to 6 Gbps effective. The Pro WX 3100 runs at a much higher base clock, which helps sustain performance under load without relying on boost states.

The API support differs in DirectX versions. The Vega 8 supports DirectX 12 (12_1), while the Pro WX 3100 supports DirectX 12 (12_0). Both support OpenGL 4.6 and Vulkan 1.3. The Vega 8 is an IGP with no bus interface beyond the integrated connection, while the Pro WX 3100 uses PCIe 3.0 x8. The Vega 8 has no power connectors and a 25 W TDP. The Pro WX 3100 also has no power connectors but carries a 65 W TDP and a suggested power supply rating of 250 W.
