AMD Radeon Pro WX 3100 vs Intel UHD Graphics 750 Comparison

The AMD Radeon Pro WX 3100 and Intel UHD Graphics 750 represent two fundamentally different approaches to graphics processing: a dedicated mobile workstation GPU versus an integrated processor solution. The benchmark data shows a near-perfect split, with each card claiming one decisive victory in the head-to-head tests. The Radeon Pro WX 3100 edges out a win in Geekbench OpenCL scoring 7,333 against 6,743, while the Intel UHD Graphics 750 counters with a Vulkan score of 8,138 versus 7,827. This 8.7% advantage for AMD in OpenCL and 3.8% lead for Intel in Vulkan suggests that the choice between these two depends heavily on the specific API and workload type.

Where Each One Wins

The AMD Radeon Pro WX 3100 establishes its dominance in OpenCL compute workloads. Its Geekbench OpenCL score of 7,333 places it 8.7% ahead of the Intel UHD Graphics 750's 6,743, indicating stronger performance in general-purpose GPU computing tasks that leverage this API. The card's 512 shading units and 32 texture mapping units provide a substantial hardware foundation for parallel processing, with a texture rate of 39.01 GTexel/s and pixel rate of 19.50 GPixel/s. This makes it the preferable option for professional applications that rely heavily on OpenCL acceleration, such as video rendering, scientific simulation, or database processing.

Conversely, the Intel UHD Graphics 750 wins in Vulkan-based workloads, posting a score of 8,138 that is 3.8% higher than the AMD card's 7,827. This advantage likely stems from its Generation 12.1 architecture, which brings more modern API feature support including DirectX 12_1 and Vulkan 1.4. The integrated GPU's higher boost clock of 1,300 MHz compared to AMD's 1,219 MHz also contributes to its Vulkan performance. For gaming or applications that leverage Vulkan's lower overhead and better multi-threading capabilities, the Intel solution demonstrates clear superiority despite its smaller hardware footprint.

The overall average benchmark scores remain close, with the AMD card achieving 7,580 and the Intel card at 7,441, a difference of roughly 1.9%. Both cards sit near the 40th percentile of all GPUs, with AMD at 41 and Intel at 40, indicating they occupy a similar performance tier in the broader market landscape.

Architecture Differences

The architectural divide between these two GPUs is stark. AMD employs the GCN 4.0 architecture on a 14 nm process from GlobalFoundries, featuring the Lexa chip with 2,200 million transistors on a 103 mm² die. This translates to a transistor density of 21.4 million transistors per square millimeter. The discrete card has dedicated 4 GB of GDDR5 memory on a 128-bit bus, delivering 96.00 GB/s of bandwidth. Its 512 shading units, 32 TMUs, and 16 ROPs provide substantial compute resources, with FP32 performance rated at 1,248.3 GFLOPS and FP16 performance at the same 1:1 ratio.

Intel's UHD Graphics 750 uses the Rocket Lake chip with Generation 12.1 architecture on a 14 nm+++ process, though Intel does not disclose transistor count or die size. As an integrated GPU, it shares system memory rather than having dedicated VRAM, with bandwidth described as "System Dependent." The hardware configuration includes 256 shading units, 16 TMUs, and 8 ROPs, half of AMD's counts. Its pixel rate of 10.40 GPixel/s and texture rate of 20.80 GTexel/s are approximately 53% of AMD's respective figures. FP32 performance of 665.6 GFLOPS is also roughly half, though FP16 performance of 1,331.2 GFLOPS at 2:1 ratio exceeds AMD's 1,248.3 GFLOPS due to its more efficient half-precision processing.

The Radeon Pro WX 3100 connects via PCIe 3.0 x8 and requires a 250 W power supply recommendation, consuming 65 W TDP. The Intel IGP operates on a Ring Bus interface with a remarkably low 15 W TDP, reflecting its integrated nature. AMD supports DisplayPort 1.4a outputs, while Intel's display connectivity is motherboard dependent. Both support DirectX 12, OpenGL 4.6, and Vulkan, though Intel's DirectX 12_1 feature level exceeds AMD's 12_0.

Head-to-Head Benchmarks

The Geekbench OpenCL test reveals a clear victory for the AMD Radeon Pro WX 3100 with a score of 7,333 against Intel's 6,743, a delta of 8.7%. This substantial margin demonstrates AMD's advantage in compute-heavy workloads that utilize OpenCL. The dedicated GDDR5 memory with 96.00 GB/s bandwidth likely plays a crucial role here, as it provides consistent high-speed access compared to Intel's system-shared memory. The discrete card's 512 shading units working at 1,219 MHz boost clock generate 1,248.3 GFLOPS of FP32 compute power, which directly translates to OpenCL performance.

However, the Vulkan benchmark flips the script. Intel's UHD Graphics 750 achieves 8,138 versus AMD's 7,827, giving Intel a 3.8% advantage. This result is particularly interesting given that Intel has half the shading units and TMUs. The newer Generation 12.1 architecture likely provides better driver optimization and hardware scheduling for Vulkan's explicit API model. The Intel card's boost clock of 1,300 MHz is 6.6% higher than AMD's 1,219 MHz, which helps compensate for its smaller compute footprint. The 2:1 FP16 ratio in Intel's architecture may also benefit certain Vulkan workloads that use half-precision calculations.

The head-to-head record stands at one win each, with the average scores of 7,580 for AMD and 7,441 for Intel placing them within 1.9% of each other. This near-parity is reflected in their competitive nearestRivals positions, where AMD's closest rival is the AMD Radeon R7 250 at 0.3% delta, while Intel's nearest rival is the AMD Radeon HD 8850M at -0.1% delta.
