AMD Radeon Pro WX 4100 vs Intel Iris Pro Graphics P6300 Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison available in the database is the Geekbench OpenCL test. The AMD Radeon Pro WX 4100 records a score of 17,642, while the Intel Iris Pro Graphics P6300 records 5,712. This gives the AMD part a lead of 208.9%, meaning it scores roughly three times higher than the Intel integrated solution in this compute-oriented workload. The margin is decisive and consistent with the positioning of the two products: a discrete workstation card versus an integrated graphics processor.

Looking at the broader benchmark suite for the AMD Radeon Pro WX 4100, the data shows strong results across multiple APIs. In Geekbench Metal, it scores 21,018, its highest recorded result. In Geekbench Vulkan, it scores 18,703. The Passmark suite shows a G3D score of 3,699, a GPU compute score of 1,475, and legacy DirectX results of 56 (DX9), 24 (DX11), 22 (DX12), and 16 (DX10). The G2D score is 646. These figures give the AMD card an average benchmark score of 6,330 across all recorded tests.

For the Intel Iris Pro Graphics P6300, the database contains only the single Geekbench OpenCL result of 5,712. Its average benchmark score is therefore identical at 5,712, since no other tests are recorded. The percentile ranking reflects this limited data: the Intel part sits at the 33rd percentile among all GPUs, while the AMD card sits at the 37th percentile. Despite the large gap in raw OpenCL scores, the percentile difference is modest, which suggests that the Intel integrated GPU is not as far behind in the broader distribution as the direct comparison might imply.

The nearest rivals in the database provide additional context. For the AMD Radeon Pro WX 4100, the closest competitors by average score are the NVIDIA GeForce GTX 460 SE and the NVIDIA GeForce GTX 580M, both at 6,389, which puts the AMD card 0.9% behind them. The AMD Radeon R7 M350 is nearly identical at 6,327, a 0.1% difference, and the NVIDIA Quadro K620 is at 6,282, a 0.8% difference. For the Intel Iris Pro Graphics P6300, the nearest rival is the NVIDIA Quadro M500M at 5,604, which the Intel part leads by 1.9%. The AMD Radeon HD 8790M sits at 5,691, a 0.4% gap, while the NVIDIA GeForce GTX 670MX at 5,721 and the NVIDIA GeForce GTX 550 Ti at 5,731 both lead the Intel part by 0.1% and 0.3%, respectively.

The Verdict

The data points to a clear overall winner in the AMD Radeon Pro WX 4100. In the only head-to-head test recorded, it outperforms the Intel Iris Pro Graphics P6300 by 208.9% in Geekbench OpenCL. The AMD card also has a more complete benchmark profile, with ten recorded tests covering Metal, Vulkan, OpenCL, and multiple DirectX versions, whereas the Intel part has just one recorded result. This disparity in available data makes direct comparisons limited, but the single shared test is unambiguous.

The AMD Radeon Pro WX 4100 should be the choice for anyone needing discrete GPU compute performance. Its 2.460 TFLOPS FP32 throughput, 96.00 GB/s memory bandwidth, and 4 GB of dedicated GDDR5 memory place it in a different class from the Intel integrated solution. The Intel Iris Pro Graphics P6300, with 614.4 GFLOPS FP32 and system-shared memory, cannot match these figures. The Intel part is better suited to scenarios where power consumption is the primary constraint, as its 15 W TDP is substantially lower than the AMD card's 50 W TDP.

The percentile data tempers the verdict slightly. The AMD card's 37th percentile versus the Intel part's 33rd percentile shows that both sit in the lower half of the overall GPU distribution. Neither product is a high-end performer by modern standards, but within this comparison, the AMD card is the stronger option. The nearest rival data confirms this: the AMD card trades places with mid-range discrete GPUs from the GTX 500 and 600 era, while the Intel part competes with entry-level mobile dGPUs like the Quadro M500M and Radeon HD 8790M.

Where Each One Wins

The AMD Radeon Pro WX 4100 wins in every measurable compute category. Its Geekbench OpenCL score of 17,642 is 208.9% higher than the Intel part's 5,712. The AMD card also has far higher theoretical throughput: 2.460 TFLOPS FP32 versus 614.4 GFLOPS, a four-to-one ratio. Pixel fill rate is 19.22 GPixel/s versus 4.800 GPixel/s, and texture fill rate is 76.86 GTexel/s versus 38.40 GTexel/s. The AMD card has 1,024 shading units, 64 TMUs, and 16 ROPs, compared to 384 shading units, 48 TMUs, and 6 ROPs on the Intel part.

The AMD card supports newer API versions across the board. DirectX 12 (12_0) versus DirectX 12 (11_1), OpenGL 4.6 versus 4.4, and Vulkan 1.3 versus 1.0. The AMD card also has dedicated display outputs with four mini-DisplayPort 1.4a connectors, while the Intel part's outputs are motherboard dependent. The AMD card is a single-slot discrete solution with no power connectors and a suggested PSU of 250 W, whereas the Intel part is an integrated graphics processor with a 15 W TDP and no separate power requirements.

The Intel Iris Pro Graphics P6300 wins only in power efficiency. Its 15 W TDP is 70% lower than the AMD card's 50 W TDP. For systems where cooling and power budgets are tight, or where a discrete GPU slot is unavailable, the Intel part is the only option. It also uses system-shared memory, which eliminates the need for dedicated VRAM and simplifies system design. The Intel part's base clock of 300 MHz and boost clock of 800 MHz are far lower than the AMD card's 1125 MHz base and 1201 MHz boost, reflecting its integrated nature and thermal constraints.
