AMD Radeon Vega 8 Mobile vs Intel UHD Graphics P750 Comparison

AMD Radeon Vega 8 Mobile and Intel UHD Graphics P750 are both end-of-life integrated graphics solutions, but the data shows a clear performance hierarchy between them. The AMD part leads the only shared benchmark by a decisive margin, while the Intel part counters with superior pixel and texture throughput on paper. This analysis breaks down the benchmark results, architectural differences, and specification gaps to determine which integrated GPU is the better choice for specific workloads.

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs is Geekbench OpenCL, and the results are unambiguous. AMD Radeon Vega 8 Mobile scores 7,435 points, while Intel UHD Graphics P750 scores 6,554 points. This gives AMD a 13.4% lead in the head-to-head comparison, making it the outright winner in the only test where both parts appear. Benchmark results indicate that this is not a marginal victory; a 13.4% delta in compute performance is substantial for integrated graphics, where gains of even a few percentage points typically separate competing IGPUs.

Contextualizing the AMD score against its nearest rivals reinforces its standing. The Vega 8 Mobile sits at the 39th percentile of all GPUs, with an average benchmark score of 7,203 points. Its closest competitor, the NVIDIA GeForce GTX 750, averages 7,222 points, placing AMD just 0.3% behind that discrete desktop card. The Vega 8 Mobile also edges out the Intel Iris Pro Graphics P580 (7,170 points, 0.5% ahead) and the NVIDIA GeForce GTX 560 SE (7,171 points, 0.4% ahead). Perhaps most notably, the data shows the Vega 8 Mobile finishes 0.6% ahead of the NVIDIA GeForce GTX 970, a high-end discrete GPU from a previous generation. This suggests that the AMD IGP is competitive with entry-level discrete graphics cards, not just other integrated solutions.

The Intel UHD Graphics P750, meanwhile, sits at the 38th percentile of all GPUs, just one point below the AMD part, with an average benchmark score of 6,554 points. Its nearest rival is the AMD Radeon HD 7730M, which averages 6,581 points, placing the Intel part 0.4% behind. The P750 also trails the AMD Radeon R7 M460 (6,612 points, 0.9% behind) but leads the NVIDIA GeForce GTX 670M (6,513 points, 0.6% ahead) and the NVIDIA GeForce GT 555M (6,493 points, 0.9% ahead). While the Intel part is competitive within its own peer group, the 13.4% gap to the Vega 8 Mobile is the dominant headline from the head-to-head data.

Where Each One Wins

The AMD Radeon Vega 8 Mobile wins decisively in raw compute performance, as evidenced by its Geekbench OpenCL score. With an FP32 throughput of 1,127.4 GFLOPS, the Vega 8 Mobile delivers nearly double the compute horsepower of the Intel part, which manages only 665.6 GFLOPS. This makes the AMD IGP the clear choice for workloads that rely on general-purpose GPU compute, such as OpenCL-accelerated applications, video encoding, and physics simulations. The Vega 8 Mobile also wins on shading units, featuring 512 shaders against Intel's 256, which directly explains its compute advantage.

The Intel UHD Graphics P750, however, wins in several rasterization-focused metrics. Its pixel rate of 41.60 GPixel/s is dramatically higher than the AMD part's 8.808 GPixel/s — a nearly 4.7x advantage. Similarly, the Intel part's texture rate of 83.20 GTexel/s vastly outpaces the AMD's 35.23 GTexel/s. The P750 achieves this with 64 TMUs and 32 ROPs, compared to the Vega 8 Mobile's 32 TMUs and 8 ROPs. For fill-rate-bound workloads, such as high-resolution 2D rendering or certain legacy 3D games that depend heavily on pixel throughput, the Intel part has a structural advantage that its lower compute score does not reflect.

In Vulkan performance, the AMD part has a measured score of 6,970 points from its benchmark suite, though the Intel part lacks a Vulkan score in the data. This suggests the Vega 8 Mobile has broader API coverage in testing, but the absence of an Intel Vulkan score prevents a direct comparison. The AMD part also wins on transistor count, featuring 4,940 million transistors on a 210 mm² die, whereas the Intel part has no transistor or die size data available.

Architecture Differences

The two GPUs represent fundamentally different architectural approaches. AMD Radeon Vega 8 Mobile uses the GCN 5.0 architecture, built on a 14nm process at GlobalFoundries. It belongs to the Vega IGP generation (Raven Ridge-M) and is the successor to GCN 3.0 IGP parts, with its own successor being Navi II IGP. Intel UHD Graphics P750, by contrast, uses the Generation 12.1 architecture, built on Intel's 14nm+++ process. It belongs to the HD Graphics-W (Rocket Lake) generation, reflecting its integration into Intel's Rocket Lake processors.

The process nodes differ in refinement: AMD uses a standard 14nm node, while Intel employs 14nm+++, which is a more mature and optimized variant of the 14nm process. Despite this, the AMD part achieves a transistor density of 23.5M per mm², a metric the Intel part does not report. The AMD chip is named Raven-M, while the Intel chip is named Rocket Lake, indicating their different integration targets — Raven Ridge-M for AMD's mobile APUs and Rocket Lake for Intel's desktop-oriented processors.

The memory architecture is identical in configuration: both use System Shared memory, with System Shared size, type, and bus width, and bandwidth that is System Dependent. This means neither GPU has dedicated VRAM, and both rely on the host system's memory bandwidth, which can vary based on the platform. The API support shows a split: both support DirectX 12 (12_1) and OpenGL 4.6, but AMD supports Vulkan 1.3 while Intel supports Vulkan 1.4, giving Intel a slight API version advantage.

Specification Differences

The specification sheets reveal several distinct differences between the two integrated GPUs. Clock speeds differ notably: AMD Radeon Vega 8 Mobile has a base clock of 300 MHz and a boost clock of 1,101 MHz, while Intel UHD Graphics P750 has a base clock of 350 MHz and a boost clock of 1,300 MHz. Intel's clocks are higher in both cases, but AMD's compute advantage comes from its larger shader count.

The shading units are the most significant split: AMD has 512 shading units, while Intel has 256 — exactly half. However, Intel reverses this in other units: AMD has 32 TMUs and 8 ROPs, while Intel has 64 TMUs and 32 ROPs. This explains the pixel and texture rate disparities. The FP32 compute figures follow the shader count: AMD produces 1,127.4 GFLOPS versus Intel's 665.6 GFLOPS. FP16 performance also favors AMD, which delivers 2.255 TFLOPS (2:1) against Intel's 1,331.2 GFLOPS (2:1).

Power consumption differs as well: AMD Radeon Vega 8 Mobile has a TDP of 25 W, while Intel UHD Graphics P750 has a TDP of 15 W. This makes the Intel part more power-efficient in absolute terms. The bus interface also differs — AMD uses an IGP interface, while Intel uses a Ring Bus. Display outputs are platform-dependent for both, with AMD listing "Portable Device Dependent" and Intel listing "Motherboard Dependent," reflecting their different target platforms. The production status is end-of-life for both, and neither has a launch MSRP listed.

The Verdict

The data points to a clear split decision. For compute-heavy tasks, the AMD Radeon Vega 8 Mobile is the superior choice. Its 13.4% lead in Geekbench OpenCL, combined with 512 shading units and 1,127.4 GFLOPS of FP32 performance, makes it the better option for OpenCL workloads and general-purpose GPU compute. The AMD part also holds its own against discrete GPUs, sitting just 0.3% behind the NVIDIA GeForce GTX 750 and ahead of the GeForce GTX 970, which suggests it can handle tasks typically reserved for entry-level discrete cards.

For fill-rate-bound applications, the Intel UHD Graphics P750 is the better pick. Its 41.60 GPixel/s pixel rate and 83.20 GTexel/s texture rate dwarf the AMD part's figures, and its 64 TMUs and 32 ROPs provide a structural advantage in rasterization-heavy scenarios. The Intel part also consumes less power, with a 15 W TDP versus AMD's 25 W, making it more suitable for thermally constrained systems.

The benchmark data ultimately favors AMD in the single head-to-head test, but the Intel part's rasterization strengths mean it is not without merit. Users prioritizing compute performance should choose the AMD Radeon Vega 8 Mobile; users prioritizing pixel throughput and power efficiency should select the Intel UHD Graphics P750. Both are end-of-life products, so the choice depends entirely on workload requirements rather than future support.
