AMD Radeon 780M vs Intel Arc Graphics 1 Xe Mobile Comparison

The Verdict

The data shows a decisive performance gap between these two integrated graphics solutions. The AMD Radeon 780M holds a 61st percentile ranking among all GPUs in the database, while the Intel Arc Graphics 1 Xe Mobile sits at the 50th percentile. The Radeon 780M's average benchmark score of 17,588 across recorded tests places it in direct competition with discrete desktop cards like the AMD Radeon Pro 560 (0.2% ahead) and the NVIDIA GeForce RTX 4060 (0.3% behind). The Intel part, by contrast, has no recorded benchmark scores in the database, leaving its average at zero.

For system builders, the Radeon 780M is the clear choice for any workload involving 3D rendering, gaming, or general GPU compute. Its recorded results show it delivers a 3DMark Steel Nomad DX12 score of 480, a Geekbench OpenCL score of 18,602, and a Geekbench Vulkan score of 33,683. The Intel Arc Graphics 1 Xe Mobile, with its 128 shading units and 1 ray tracing core, appears positioned for basic display output rather than demanding graphics tasks. The data indicates the AMD part is the only one of the two with measurable graphics performance.

Architecture Differences

The two chips come from different foundries and process nodes. The AMD Radeon 780M uses the Phoenix chip built on TSMC's 4 nm process, with 25,390 million transistors packed into a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The Intel Arc Graphics 1 Xe Mobile uses the Wildcat Lake chip built on Intel's own 3 nm process, though its transistor count and die size are listed as unknown in the database.

The architectural generations differ substantially. The Radeon 780M is based on RDNA 3.0, part of the Navi III IGP (Phoenix) generation. The Intel part uses Xe3-LPG, part of the Arc Graphics-M (Wildcat Lake) generation. The AMD chip is a successor to Navi II IGP, while the Intel chip succeeds HD Graphics-M.

Compute resources show a wide gap. The Radeon 780M has 768 shading units, 48 texture mapping units, 32 render output units, and 12 ray tracing cores. The Intel Arc Graphics 1 Xe Mobile has 128 shading units, 8 TMUs, 4 ROPs, and 1 ray tracing core. That is a 6x difference in shading units, a 6x difference in TMUs, and an 8x difference in ROPs.

Clock speeds also differ. The Radeon 780M runs at a base clock of 800 MHz with a boost of 2900 MHz. The Intel part has a base clock of 300 MHz and a boost of 2300 MHz. The AMD chip's higher boost clock, combined with its much larger shader array, produces a theoretical FP32 throughput of 8.909 TFLOPS versus the Intel part's 588.8 GFLOPS, a difference of roughly 15x.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use system shared memory with system dependent bandwidth. The Radeon 780M connects via PCIe 4.0 x8, while the Intel part's bus interface is listed simply as IGP. The AMD chip is rated at 15 W TDP, while the Intel part is rated at 25 W TDP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 780M and the Intel Arc Graphics 1 Xe Mobile. However, the Radeon 780M has three recorded individual benchmark results, while the Intel part has none.

In 3DMark Steel Nomad DX12, the Radeon 780M scores 480. This test exercises modern DirectX 12 rendering workloads, and the score places the AMD part in the context of much larger discrete GPUs. The Intel Arc Graphics 1 Xe Mobile has no recorded score in this test.

In Geekbench OpenCL, the Radeon 780M scores 18,602. This measures general-purpose compute performance across a range of workloads. The score positions the AMD chip within 0.2% of the AMD Radeon Pro 560 (17,551 average) and 0.5% ahead of the AMD Radeon Pro 460 (17,509 average). The Intel part has no recorded OpenCL score.

In Geekbench Vulkan, the Radeon 780M scores 33,683. This is the highest individual result among its recorded benchmarks, and it reflects the Vulkan API's efficient utilization of the RDNA 3.0 architecture's 768 shading units. The Intel Arc Graphics 1 Xe Mobile has no recorded Vulkan score.

The nearest rivals for the Radeon 780M, based on average benchmark score, include the AMD Radeon Pro 560 at 17,551 (0.2% behind the 780M), the NVIDIA GeForce RTX 4060 at 17,639 (0.3% ahead), the AMD Radeon HD 7790 at 17,666 (0.4% ahead), and the AMD Radeon Pro 460 at 17,509 (0.5% behind). These deltas are small, indicating the Radeon 780M sits in a tight performance cluster with those discrete cards despite being an integrated part.

The Intel Arc Graphics 1 Xe Mobile has no nearest rivals listed and no average benchmark score, meaning the database has no measured performance data for it. Its 50th percentile ranking appears to be a default placement rather than a result of testing. The Radeon 780M's 61st percentile reflects actual measured results.

The theoretical specifications reinforce the benchmark gap. The Radeon 780M's FP32 throughput of 8.909 TFLOPS is 15.1x the Intel part's 588.8 GFLOPS. The pixel rate difference is 10.1x, and the texture rate difference is 7.6x. The Radeon 780M also has 12 ray tracing cores versus 1, and 768 shading units versus 128. The Intel part's higher TDP of 25 W versus 15 W does not translate into higher performance, as its clock speeds are lower and its compute unit count is much smaller.

Release timing also differs. The Radeon 780M was released on 2024-01-30, while the Intel Arc Graphics 1 Xe Mobile is dated 2026-04-15. The Radeon 780M remains an active product with a successor in the Navi III IGP line, while the Intel part has no successor listed. The data shows the AMD part as the only one of the two with verifiable graphics performance in the database.
