AMD Radeon Pro WX 4100 vs Intel UHD Graphics P750 Comparison

The AMD Radeon Pro WX 4100 is the clear performance leader in this matchup, delivering a Geekbench OpenCL score of 17,642 compared to the Intel UHD Graphics P750's 6,554. That represents a 62.9% deficit for the Intel part, which sits at the 38th percentile of all GPUs while the AMD card sits at the 37th — a statistical tie in overall standing despite the massive raw score gap. The Intel P750's nearest rivals include the AMD Radeon HD 7730M (6,581, -0.4%) and the NVIDIA GeForce GTX 670M (6,513, +0.6%), placing it firmly in entry-level mobile territory. The WX 4100, meanwhile, trades blows with the NVIDIA Quadro K620 (6,282, +0.8%) and the AMD Radeon R7 M350 (6,327, +0.1%), which is surprising given its much higher compute throughput.

Head-to-Head Benchmarks

The only shared benchmark between these two GPUs is Geekbench OpenCL, and the results are lopsided. The AMD Radeon Pro WX 4100 scores 17,642 while the Intel UHD Graphics P750 manages just 6,554, giving AMD a 62.9% advantage. This is not a marginal win — the AMD part delivers roughly 2.7 times the raw compute throughput in this test. For context, the Intel P750's score places it just 0.9% above the NVIDIA GeForce GT 555M (6,493) and 0.6% above the GTX 670M (6,513), meaning it barely outruns decade-old mobile discrete GPUs. The WX 4100, by contrast, outperforms its nearest rival, the AMD Radeon R7 M350 (6,327), by 0.1% on average, but its OpenCL score is far above that average, suggesting it shines in this specific workload.

The Intel P750's best showing comes in raw throughput metrics where its 256 shading units, 64 TMUs, and 32 ROPs produce a pixel rate of 41.60 GPixel/s and a texture rate of 83.20 GTexel/s. Those figures actually exceed the WX 4100's 19.22 GPixel/s and 76.86 GTexel/s, respectively. This is a classic case of a GPU with fewer shaders but higher clocks and more ROPs doing better at fill-rate-bound tasks. The WX 4100 counters with 1,024 shading units — four times the Intel part — and a FP32 throughput of 2.460 TFLOPS versus the P750's 665.6 GFLOPS. That is a 3.7-fold difference in raw compute, which explains the OpenCL gap.

Where the WX 4100 truly dominates is in its broader benchmark suite. It posts a Geekbench Vulkan score of 18,703 and a Metal score of 21,018, though the Intel P750 has no comparable results in those APIs. In DirectX legacy tests, the WX 4100 scores 56 in DirectX 9, 24 in DirectX 11, 22 in DirectX 12, and 16 in DirectX 10. Its Passmark G3D score of 3,699 and GPU compute score of 1,475 further underscore its compute-oriented design. The Intel P750 has no Passmark results in the FACT PACK, so the comparison rests entirely on OpenCL and theoretical fill rates.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel UHD Graphics P750 is built on Intel's Generation 12.1 architecture, using the Rocket Lake chip and a 14 nm+++ process node manufactured by Intel itself. It is an integrated graphics processor (IGP) that connects via a Ring Bus interface, with no dedicated video memory — it relies entirely on system-shared memory. The architecture is designed for efficiency and basic display output, with a TDP of just 15 W, making it suitable for low-power systems where discrete graphics are impractical.

The AMD Radeon Pro WX 4100 uses the older GCN 4.0 architecture on the Baffin chip, built on a 14 nm process at GlobalFoundries. This is a discrete, single-slot card with 3,000 million transistors on a 123 mm² die, giving it a transistor density of 24.4M per mm². GCN 4.0 is a compute-heavy architecture that trades some fill-rate efficiency for raw shader throughput, which is why it has four times the shading units of the Intel part. It connects via PCIe 3.0 x8 and has its own 4 GB of GDDR5 memory with a 128-bit bus, providing 96.00 GB/s of dedicated bandwidth — a critical advantage for compute workloads that need consistent memory access.

The API support differs as well. The Intel P750 supports DirectX 12 (12_1) and Vulkan 1.4, while the WX 4100 supports DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6. The higher Vulkan version on the Intel part is notable, but the WX 4100's actual Vulkan benchmark score of 18,703 shows that API version alone doesn't determine performance. The Intel part's FP16 throughput is listed at 1,331.2 GFLOPS (2:1 ratio), while the AMD part does FP16 at 2.460 TFLOPS (1:1 ratio), meaning the WX 4100 treats FP16 and FP32 with equal throughput — a feature that matters for certain compute workloads.

Specification Differences

The most striking difference is in shading units: the AMD WX 4100 has 1,024, versus 256 for the Intel P750. Both have 64 TMUs, but the Intel part has 32 ROPs to AMD's 16, which explains the fill-rate advantage for Intel. The clock speeds differ significantly — Intel's base clock is 350 MHz with a 1,300 MHz boost, while AMD runs at 1,125 MHz base and 1,201 MHz boost. The AMD card's much higher base clock compensates for its lower boost headroom.

Memory is entirely different: the Intel P750 uses system-shared memory with system-dependent bandwidth, while the WX 4100 has 4 GB of GDDR5 on a 128-bit bus delivering 96.00 GB/s. The WX 4100 has a memory clock of 1,500 MHz (6 Gbps effective), and the Intel part's memory clock is listed as "System Shared." Power consumption is another divider: the Intel IGP runs at 15 W TDP, while the AMD card draws 50 W and requires a 250 W suggested PSU, though it needs no external power connectors. The WX 4100 is a single-slot card measuring 168 mm (6.6 inches) long and 69 mm (2.7 inches) high, with four mini-DisplayPort 1.4a outputs. The Intel P750's display outputs are motherboard-dependent, as expected for an IGP.

The AMD card has 3,000 million transistors on a 123 mm² die with a density of 24.4M per mm²; the Intel P750's transistor count and die size are not listed. The AMD card's slot is single-slot, while the Intel part is an IGP with no slot width. The bus interfaces also differ: PCIe 3.0 x8 for AMD versus Ring Bus for Intel. The WX 4100 has a release date of November 9, 2016, with a predecessor of Radeon Pro GCN and successor of Radeon Pro Vega; the Intel P750 has no release date or predecessor/successor listed. Both are end-of-life products.

The Verdict

The data points to a clear choice for anyone needing compute performance: the AMD Radeon Pro WX 4100 wins the only shared benchmark by 62.9%, and its FP32 throughput is 3.7 times higher. The Intel UHD Graphics P750 is not competitive in raw compute and should only be considered for systems where an integrated GPU is the only option due to power or space constraints. However, the Intel part does win in pixel rate (41.60 versus 19.22 GPixel/s) and slightly in texture rate (83.20 versus 76.86 GTexel/s), which means it could be better for certain fill-rate-bound 2D workloads or basic display tasks.

The WX 4100's dedicated 4 GB GDDR5 memory with 96.00 GB/s bandwidth is a major practical advantage over system-shared memory, as it guarantees consistent memory performance regardless of system RAM speed. The Intel P750's memory bandwidth is "system dependent," which introduces variability that can hurt compute workloads. For professional applications that are OpenCL or Vulkan heavy, the WX 4100 is the only rational choice. For a lightweight office or media PC where the GPU is incidental, the P750's 15 W TDP and integrated nature make it a reasonable default.

Where Each One Wins

Intel UHD Graphics P750 wins in: Pixel fill rate (41.60 GPixel/s versus 19.22 GPixel/s), texture fill rate (83.20 GTexel/s versus 76.86 GTexel/s), ROP count (32 versus 16), power efficiency (15 W TDP versus 50 W), and Vulkan API version support (1.4 versus 1.3). These advantages make it better suited for basic 2D acceleration, low-resolution rendering, and any scenario where power draw is the primary concern.

AMD Radeon Pro WX 4100 wins in: Geekbench OpenCL (17,642 versus 6,554, a 62.9% lead), shading units (1,024 versus 256), FP32 compute (2.460 TFLOPS versus 665.6 GFLOPS), FP16 compute (2.460 TFLOPS versus 1,331.2 GFLOPS), dedicated memory (4 GB GDDR5 versus system-shared), memory bandwidth (96.00 GB/s versus system-dependent), base clock speed (1,125 MHz versus 350 MHz), and transistor count (3,000 million versus not listed). It also has a higher boost clock (1,201 MHz versus 1,300 MHz for the Intel part — wait, that is not a win; the Intel boost is higher). The WX 4100 wins on sustained compute workloads, professional rendering, and any task that benefits from dedicated VRAM. Its 1:1 FP16 ratio is a specific advantage for workloads that use mixed-precision math.
