The Intel Arc Graphics 1 Xe Mobile has no recorded benchmark scores, an average benchmark score of 0, and a percentile rank of 50.

Architecture Differences

The architectural gap between these two GPUs is substantial. The AMD Radeon RX 7800M uses the RDNA 3.0 architecture on the Navi 32 chip, built at TSMC's 5 nm process. It belongs to the Navi Mobile (RX 7000M) generation with the codename Wheat Nas. The Intel Arc Graphics 1 Xe Mobile uses the Xe3-LPG architecture on the Wildcat Lake chip, fabricated at Intel's 3 nm process, and belongs to the Arc Graphics-M (Wildcat Lake) generation.

The compute resources differ by an order of magnitude. The AMD GPU provides 3840 shading units, 240 texture mapping units, and 96 render output units. It also includes 60 ray tracing cores. The Intel GPU offers only 128 shading units, 8 TMUs, and 4 ROPs, with a single ray tracing core. This disparity directly translates into peak throughput figures: the AMD part delivers 35.87 TFLOPS of FP32 compute and 35.87 TFLOPS of FP16 (at a 1:1 ratio). The Intel part delivers 588.8 GFLOPS of FP32 and 1,177.6 GFLOPS of FP16 (at a 2:1 ratio). The difference is roughly 61x in FP32 throughput.

Memory architecture also separates them. The RX 7800M has dedicated 12 GB GDDR6 memory on a 192-bit interface with 432.0 GB/s bandwidth. The Arc Graphics 1 Xe Mobile uses System Shared memory for both capacity and bandwidth, meaning its memory subsystem depends entirely on the host system. Clock behavior differs as well: the AMD GPU has a base clock of 1295 MHz, a game clock of 2145 MHz, and a boost clock of 2335 MHz, with memory running at 2250 MHz (18 Gbps effective). The Intel GPU has a base clock of 300 MHz and a boost clock of 2300 MHz, with no separate game clock or dedicated memory clock.

Process technology and power envelopes reinforce the positioning. The RX 7800M is built on a 5 nm TSMC process with 28,100 million transistors on a 346 mm² die. The Arc Graphics 1 Xe Mobile uses Intel's 3 nm process, though its transistor count and die size are unknown. The power draw is starkly different: 180 W for the AMD part versus 25 W for the Intel part. Both use an IGP slot width, have no power connectors, and list display outputs as Portable Device Dependent.

Where Each One Wins

The AMD Radeon RX 7800M wins decisively in raw performance metrics. Its recorded benchmark scores reflect a GPU designed for demanding gaming and compute workloads on mobile platforms. The 3DMark Steel Nomad DX12 score of 2994 and Geekbench Vulkan score of 126668 indicate strong DirectX 12 and Vulkan performance. The Passmark G3D score of 17613 and GPU compute score of 9342 further confirm its capability in both graphics and general-purpose compute scenarios. The average benchmark score of 27883 places it at the 73rd percentile among all GPUs in the database, showing it outperforms roughly three-quarters of tracked devices.

The Intel Arc Graphics 1 Xe Mobile has no recorded benchmark scores in the database, so its wins cannot be quantified from measurements. Its advantages lie in the specifications that favor integrated graphics: a 25 W TDP versus 180 W, and the absence of a dedicated memory subsystem, meaning it shares system memory and saves on component cost and complexity. The 3 nm process node suggests efficiency gains, but without benchmark data, the database cannot confirm performance outcomes.

The use-case split is clear from the data. The RX 7800M is positioned for performance-critical workloads: high-fidelity gaming, content creation, and compute acceleration where dedicated memory bandwidth and high shader counts matter. The Arc Graphics 1 Xe Mobile is positioned for power-constrained environments: thin-and-light laptops, basic graphics output, and workloads that do not require discrete GPU performance. Its system-shared memory and low TDP make it suitable for integrated use, but the lack of benchmark scores means its actual performance ceiling remains undocumented.

The AMD GPU uses PCIe 4.0 x16, while the Intel GPU connects via IGP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two GPUs, and the Intel Arc Graphics 1 Xe Mobile has an empty benchmark record. The comparison must therefore rely on the AMD GPU's recorded scores and the Intel GPU's specification-derived expectations.

For the AMD Radeon RX 7800M, the strongest recorded result is the Geekbench Vulkan score of 126668, which indicates robust Vulkan API performance. The Geekbench OpenCL score of 120778 shows similar strength in OpenCL compute workloads. The 3DMark Steel Nomad DX12 score of 2994 reflects modern DirectX 12 gaming performance. In Passmark tests, the G3D score of 17613 stands out, while GPU compute scores 9342. The DirectX 11 score of 176 and DirectX 9 score of 174 are nearly identical, suggesting consistent legacy API performance. DirectX 10 scores 99, DirectX 12 scores 89, and G2D scores 892.

The average benchmark score of 27883 places the RX 7800M at the 73rd percentile. Its nearest rivals in the database are all within a narrow band: the AMD Radeon Pro Vega 20 scores 27839 (0.2% behind), the AMD Radeon Pro W5500X scores 27973 (0.3% ahead), the NVIDIA GeForce GTX 980 Ti scores 28020 (0.5% ahead), and the AMD FirePro S7150 scores 28117 (0.8% ahead). These deltas show the RX 7800M sits in a tightly contested performance tier, trading places with older workstation and high-end desktop GPUs.

The Intel Arc Graphics 1 Xe Mobile has no scores to compare, so its wins cannot be measured. Its specifications suggest it would be dramatically slower: 128 shading units versus 3840, 8 TMUs versus 240, 4 ROPs versus 96, and FP32 throughput of 588.8 GFLOPS versus 35.87 TFLOPS. The pixel rate of 9.200 GPixel/s and texture rate of 18.40 GTexel/s are similarly orders of magnitude below the AMD part's 224.2 GPixel/s and 560.4 GTexel/s. The Intel GPU's 25 W TDP versus 180 W indicates it consumes 155 W less, which is its primary spec advantage.

The Verdict

The data indicates that the AMD Radeon RX 7800M is the performance leader by every measurable metric. Its average benchmark score of 27883, 73rd percentile ranking, and strong scores across DirectX 12, Vulkan, OpenCL, and Passmark tests confirm its capability for demanding workloads. The 12 GB of dedicated GDDR6 memory with 432.0 GB/s bandwidth, 3840 shading units, and 60 ray tracing cores position it as a discrete mobile GPU for gaming and compute-intensive tasks.

The Intel Arc Graphics 1 Xe Mobile, with no recorded benchmark scores and an average score of 0, cannot be assessed for performance from the database. Its specifications indicate a fundamentally different purpose: 128 shading units, 4 ROPs, system-shared memory, and a 25 W TDP make it an integrated graphics solution for low-power devices. The 3 nm process and 2300 MHz boost clock suggest architectural efficiency, but without benchmark data, its real-world performance remains unverified.

The choice between them depends on the workload and platform. For users requiring dedicated graphics performance, high memory bandwidth, and ray tracing capability, the RX 7800M is the only option with recorded evidence of its capabilities. For users prioritizing low power consumption and integrated simplicity, the Arc Graphics 1 Xe Mobile fits that profile, though its performance is undocumented. The RX 7800M's nearest rivals, all within 0.8% of its average score, show it competes with older desktop-class GPUs from AMD and NVIDIA. The Intel GPU's 50th percentile ranking, without any scores to back it, suggests it sits at the median of all GPUs, but the database lacks confirmation.
