A: The AMD Radeon PRO W7800 uses 32 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of bandwidth. The Intel Arc Graphics 2 Xe Mobile uses system shared memory, meaning its size, type, bus width, and bandwidth are all system dependent.

Q: How do the shading unit counts differ?

A: The AMD Radeon PRO W7800 has 4,480 shading units, while the Intel Arc Graphics 2 Xe Mobile has only 256 shading units. The AMD part also has 280 texture mapping units and 128 ROPs, compared to 16 TMUs and 8 ROPs on the Intel part.

Architecture Differences

The AMD Radeon PRO W7800 is built on the RDNA 3.0 architecture, using the Navi 31 chip under the codename Plum Bonito. It belongs to the Radeon Pro Navi (Navi III Series) generation. The Intel Arc Graphics 2 Xe Mobile uses the Xe3-LPG architecture with the Wildcat Lake chip, part of the Arc Graphics-M (Wildcat Lake) generation. These represent fundamentally different design philosophies: AMD's part is a discrete workstation GPU, while Intel's is an integrated graphics processor (IGP).

The manufacturing processes differ significantly. AMD uses TSMC's 5 nm node, while Intel uses its own 3 nm process. The AMD chip is substantially larger at 529 mm² with 57,700 million transistors, yielding a transistor density of 109.1 million per square millimeter. Intel's transistor count and die size are listed as unknown in the database.

Compute resources diverge sharply. The AMD Radeon PRO W7800 has 4,480 shading units, 280 TMUs, 128 ROPs, and 70 ray tracing cores. The Intel Arc Graphics 2 Xe Mobile has 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores. The AMD part's pixel rate is 323.2 GPixel/s versus 20.00 GPixel/s for Intel. Texture rates are 707.0 GTexel/s and 40.00 GTexel/s respectively.

FP32 throughput measures 45.25 TFLOPS for AMD and 1,280.0 GFLOPS (1.28 TFLOPS) for Intel. FP16 performance is 90.50 TFLOPS for AMD versus 2.560 TFLOPS for Intel. Both figures for AMD assume a 2:1 ratio, and the database lists the same 2:1 ratio for Intel's FP16.

Clock behavior differs as well. The AMD part has a base clock of 1895 MHz and a boost clock of 2525 MHz. Intel's base clock is only 300 MHz, but its boost reaches 2500 MHz. Memory clocks are 2250 MHz (18 Gbps effective) for AMD, while Intel depends entirely on system shared memory.

Power and physical characteristics reflect their different roles. The AMD Radeon PRO W7800 has a TDP of 260 W, requires two 8-pin power connectors, occupies a dual-slot form factor, and measures 280 mm in length, 110 mm in height, and 40 mm in width. The Intel Arc Graphics 2 Xe Mobile has a TDP of 25 W, uses no power connectors, and is an IGP with no listed dimensions. The suggested power supply for AMD is 600 W; Intel lists none.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with AMD offering 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, while Intel's outputs are portable device dependent.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark results between the AMD Radeon PRO W7800 and the Intel Arc Graphics 2 Xe Mobile. The Intel part has no benchmark entries at all, and its average benchmark score is recorded as zero. The AMD part, by contrast, has two recorded benchmark scores: 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan.

The absence of Intel benchmark data makes direct numerical comparison impossible. However, the AMD part's recorded scores place it in a specific competitive context. Its average score of 164,894 sits 0.2% below the NVIDIA RTX A5500 (165,217), 0.7% below the NVIDIA RTX 4500 Ada Generation (166,094), and 2.2% below the AMD Radeon Pro W6900X (168,574). It exceeds the NVIDIA A100 PCIe 40 GB (162,504) by 1.5%.

The Intel Arc Graphics 2 Xe Mobile sits at the 50th percentile among all GPUs, which is the median position. The AMD Radeon PRO W7800 sits at the 97th percentile. That 47-percentage-point gap in percentile ranking, combined with the absence of any Intel benchmark scores, indicates a substantial performance separation.

In raw compute terms, the database shows AMD's FP32 throughput of 45.25 TFLOPS versus Intel's 1,280.0 GFLOPS, a ratio of roughly 35 to 1. Pixel rate favors AMD at 323.2 GPixel/s versus 20.00 GPixel/s, a ratio of roughly 16 to 1. Texture rate favors AMD at 707.0 GTexel/s versus 40.00 GTexel/s, a ratio of roughly 18 to 1. Memory bandwidth cannot be compared directly because Intel's bandwidth is system dependent.

The Verdict

The recorded data indicates that the AMD Radeon PRO W7800 and the Intel Arc Graphics 2 Xe Mobile serve entirely different purposes. The AMD part is a discrete workstation GPU with a 97th percentile ranking, 32 GB of dedicated GDDR6 memory, and a 260 W power envelope. The Intel part is a 25 W integrated GPU with system shared memory and no recorded benchmarks.

For workloads requiring high-throughput compute, large dedicated memory pools, or sustained rendering performance, the AMD Radeon PRO W7800 is the only option with supporting data. Its 45.25 TFLOPS FP32 throughput, 576.0 GB/s bandwidth, and 70 ray tracing cores place it in the top tier of recorded GPUs. The Intel Arc Graphics 2 Xe Mobile cannot match any of these specifications, and the database contains no benchmark evidence to suggest otherwise.

For mobile or low-power integrated graphics scenarios, the Intel part is the only one that fits. It is classified as an IGP, requires no power connectors, and consumes 25 W. The AMD part requires a 600 W power supply, two 8-pin connectors, and a dual-slot chassis. These are not competing products in the same market segment.

The release dates reinforce this separation. The AMD Radeon PRO W7800 launched on April 12, 2023. The Intel Arc Graphics 2 Xe Mobile is dated April 15, 2026. The AMD part's predecessor is the Radeon Pro Vega, while Intel's predecessor is the HD Graphics-M.

The data supports a straightforward conclusion: the AMD Radeon PRO W7800 delivers workstation-class compute with verified benchmark scores, while the Intel Arc Graphics 2 Xe Mobile is a low-power integrated solution with no recorded performance data. Selection between them depends entirely on whether the target platform is a discrete workstation build or a compact mobile device.
