AMD Radeon PRO W7800 vs Intel Arc Graphics 1 Xe Mobile Comparison

The AMD Radeon PRO W7800 and the Intel Arc Graphics 1 Xe Mobile represent two extremes in the GPU landscape. The data shows a professional workstation card with a 97th percentile ranking against all GPUs, while the Intel part is an integrated mobile processor graphics solution sitting at the 50th percentile. Their performance profiles are defined by a massive gulf in specifications and benchmark results.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs between these two parts, but the recorded aggregate scores are starkly illustrative. The AMD Radeon PRO W7800 posts an average benchmark score of 164,894, based on a Geekbench OpenCL result of 154,366 and a Geekbench Vulkan score of 175,422. The Intel Arc Graphics 1 Xe Mobile has no recorded benchmark scores in the database, resulting in an average benchmark score of 0.

This performance disparity is rooted in the silicon. The AMD part uses the Navi 31 chip with RDNA 3.0 architecture, while the Intel part uses the Wildcat Lake chip with Xe3-LPG architecture. The W7800 delivers 45.25 TFLOPS of FP32 compute, a figure that dwarfs the Intel part's 588.8 GFLOPS. In terms of texture processing, the AMD card hits 707.0 GTexel/s against the Intel's 18.40 GTexel/s. Pixel throughput shows a similar chasm: 323.2 GPixel/s for the Radeon versus 9.200 GPixel/s for the Intel.

The W7800's nearest rivals in the database provide context for its performance tier. It sits within 0.2% of the NVIDIA RTX A5500 (average score 165,217) and 0.7% below the NVIDIA RTX 4500 Ada Generation (average score 166,094). It leads the NVIDIA A100 PCIe 40 GB (average score 162,504) by 1.5% and trails the AMD Radeon Pro W6900X (average score 168,574) by 2.2%. These margins are minimal, placing the W7800 in a tightly contested professional segment.

The Intel Arc Graphics 1 Xe Mobile, by contrast, has no nearest rivals listed and no scores to compare. Its 50th percentile ranking places it in the middle of all GPUs, a position consistent with an integrated solution designed for basic graphical output rather than compute-heavy workloads.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every measurable compute and rendering category in this comparison. Its 32 GB of GDDR6 memory on a 256-bit bus delivers 576.0 GB/s of bandwidth, enabling large dataset manipulation and high-resolution texture streaming. The Intel part relies on System Shared memory, with bandwidth described as System Dependent, which cannot match dedicated VRAM performance.

The W7800's 70 ray tracing cores provide hardware-accelerated ray tracing, a feature present in the Intel part through a single RT core. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but the scale of execution resources differs enormously. The AMD GPU packs 4480 shading units, 280 TMUs, and 128 ROPs. The Intel integrated graphics uses 128 shading units, 8 TMUs, and 4 ROPs.

The architecture differences reinforce the separation. The Radeon PRO W7800 uses a 5 nm TSMC process with 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The Intel part uses a 3 nm Intel process, but its transistor count and die size are listed as unknown. The AMD card is a dual-slot, 260 W discrete component requiring a 600 W power supply and two 8-pin connectors. The Intel part is an IGP with a 25 W TDP, no power connectors, and no suggested PSU requirement.

For workloads like FP32 compute, the W7800's 45.25 TFLOPS versus the Intel's 588.8 GFLOPS means the AMD card processes roughly 77 times the data per second. FP16 performance shows 90.50 TFLOPS for the AMD card versus 1,177.6 GFLOPS for the Intel part. Texture rate, pixel rate, and memory bandwidth all follow the same pattern: the dedicated workstation card outperforms the integrated mobile solution by orders of magnitude.

The Intel Arc Graphics 1 Xe Mobile wins in power efficiency and physical footprint. Its 25 W TDP compares to 260 W for the Radeon, and as an IGP it requires no additional slot width, power connectors, or system power supply headroom beyond what the host device provides. Its 9.200 GPixel/s and 18.40 GTexel/s rates are modest but appropriate for a low-power integrated part.

The Verdict

The data indicates that the AMD Radeon PRO W7800 is designed for professional visualization, rendering, and compute tasks. Its average benchmark score of 164,894 places it in the 97th percentile of all GPUs, with performance statistically indistinguishable from the NVIDIA RTX A5500 and RTX 4500 Ada Generation. The 32 GB VRAM and 576.0 GB/s bandwidth suit large models and multi-display output, supported by three DisplayPort 2.1 outputs and one mini-DisplayPort 2.1.

The Intel Arc Graphics 1 Xe Mobile serves a fundamentally different purpose. As an integrated processor graphics solution with a 25 W TDP, it provides display output and basic acceleration for portable devices. Its specifications, including 128 shading units and 588.8 GFLOPS FP32, are consistent with entry-level integrated graphics. The 50th percentile ranking reflects a middle-of-the-road position among all GPUs, but this is a comparison across all parts, including those that cannot run standalone benchmarks.

For users requiring compute power, the W7800 is the clear choice. The data shows no scenario where the Intel part approaches its performance. The W7800's nearest rivals are all professional workstation or data center parts, confirming its positioning. The Intel part, with no recorded benchmarks and no nearest rivals, occupies a separate category entirely.

For portable devices needing minimal power draw and no discrete GPU slot, the Intel Arc Graphics 1 Xe Mobile is the appropriate option. Its 3 nm process and IGP form factor allow integration into compact systems. The database does not include any benchmark scores for this part, so its actual compute performance compared to other integrated GPUs cannot be quantified from this data alone.
