Architecture Differences
The AMD Radeon 8040S and Intel Arc Graphics 4 Xe Mobile represent two distinct approaches to integrated graphics. The AMD part uses the RDNA 3.5 architecture on the Strix Halo chip, fabricated on a 4 nm TSMC process with a die size of 308 mm². The Intel part uses the Xe3-LPG architecture on the Panther Lake chip and is fabricated on Intel's 3 nm process, with the die size listed as unknown in the database.
The compute resources differ substantially. The AMD Radeon 8040S carries 1024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. The Intel Arc Graphics 4 Xe Mobile carries 512 shading units, 32 texture mapping units, 16 ROPs, and 4 ray tracing cores. In every compute category, the AMD GPU has exactly double the hardware of the Intel GPU.
Memory architecture is shared system memory for both parts, with system-dependent bandwidth. Both GPUs are integrated into the package as IGP solutions with no power connectors and portable-device-dependent display outputs. The AMD GPU connects via PCIe 5.0 x16, while the Intel GPU uses an IGP bus interface.
The RDNA 3.5 architecture on AMD delivers FP32 performance of 5.734 TFLOPS with FP16 at the same 5.734 TFLOPS rate (1:1 ratio). The Xe3-LPG architecture on Intel delivers FP32 performance of 2.355 TFLOPS and FP16 performance of 4.710 TFLOPS, which is a 2:1 ratio. This indicates that the Intel architecture can double its throughput when operating in FP16 mode, while the AMD architecture maintains a consistent 1:1 ratio.
Head-to-Head Benchmarks
The database records no direct head-to-head benchmark comparisons between the AMD Radeon 8040S and the Intel Arc Graphics 4 Xe Mobile. The head-to-head benchmark array is empty, and the wins counters for both sides show zero. The Intel Arc Graphics 4 Xe Mobile also has an empty benchmark array in the database, meaning no Passmark scores have been recorded for it.
For the AMD Radeon 8040S, the available Passmark results provide a reference point. The GPU scores 10578 in Passmark G3D, 5138 in Passmark GPU Compute, 1052 in Passmark G2D, 134 in Passmark DirectX 9, 80 in Passmark DirectX 11, 48 in Passmark DirectX 10, and 47 in Passmark DirectX 12. The average benchmark score across all recorded tests is 2440.
The AMD Radeon 8040S sits at the 17th percentile among all GPUs in the database. Its nearest rivals in the recorded data are the NVIDIA GeForce 710M with an average score of 2433, the Intel HD Graphics 610 with 2425, the NVIDIA GeForce GT 710M with 2422, and the AMD Radeon RX 7400 with 2467. The delta percentages show the 8040S is 0.3% ahead of the GeForce 710M, 0.6% ahead of the HD Graphics 610, 0.7% ahead of the GT 710M, and 1.1% behind the Radeon RX 7400.
Because the Intel Arc Graphics 4 Xe Mobile has no benchmark scores recorded in the database, its average benchmark score is listed as 0, and it has no nearest rivals. The database does place it at the 50th percentile among all GPUs, which is a positional ranking rather than a performance measurement. The absence of recorded data for the Intel part means no direct numerical comparison can be made between the two GPUs in the benchmark section.
Specification Differences
The two GPUs differ across nearly every measured specification. The process node differs: the AMD Radeon 8040S uses 4 nm from TSMC, while the Intel Arc Graphics 4 Xe Mobile uses 3 nm from Intel. The die size is 308 mm² for AMD, while Intel's die size is unknown.
Clock speeds differ significantly. The AMD Radeon 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz. The Intel Arc Graphics 4 Xe Mobile has a base clock of 300 MHz and a boost clock of 2300 MHz.
Compute unit counts differ by a factor of two across the board. The AMD GPU has 1024 shading units, 64 TMUs, 32 ROPs, and 16 RT cores. The Intel GPU has 512 shading units, 32 TMUs, 16 ROPs, and 4 RT cores.
Pixel and texture rates reflect the clock and unit differences. The AMD GPU achieves a pixel rate of 89.60 GPixel/s and a texture rate of 179.2 GTexel/s. The Intel GPU achieves a pixel rate of 36.80 GPixel/s and a texture rate of 73.60 GTexel/s.
FP32 throughput is 5.734 TFLOPS for AMD versus 2.355 TFLOPS for Intel. FP16 throughput is 5.734 TFLOPS for AMD versus 4.710 TFLOPS for Intel. The TDP also differs: 55 W for AMD versus 25 W for Intel.
The bus interface differs, with the AMD GPU using PCIe 5.0 x16 and the Intel GPU using an IGP interface. The release dates differ as well, with the AMD Radeon 8040S released on 2025-01-05 and the Intel Arc Graphics 4 Xe Mobile released on 2026-01-26. The AMD GPU lists Polaris Mobile as its predecessor, while the Intel GPU has no predecessor listed. Neither GPU has a launch MSRP recorded in the database.
The Verdict
The recorded data shows a clear structural advantage for the AMD Radeon 8040S in raw compute resources. It doubles the Intel Arc Graphics 4 Xe Mobile in shading units, texture mapping units, ROPs, and ray tracing cores. Its boost clock of 2800 MHz exceeds Intel's 2300 MHz, and its FP32 throughput of 5.734 TFLOPS is more than double Intel's 2.355 TFLOPS. The pixel rate of 89.60 GPixel/s and texture rate of 179.2 GTexel/s are both more than double the Intel part's respective rates of 36.80 GPixel/s and 73.60 GTexel/s.
However, the Intel Arc Graphics 4 Xe Mobile has no recorded benchmark scores in the database, so the measured performance comparison cannot be completed. The Intel part also carries a significantly lower TDP of 25 W versus 55 W, which indicates a different design target. The Intel GPU uses a 3 nm process compared to AMD's 4 nm process, and its FP16 throughput of 4.710 TFLOPS is closer to AMD's 5.734 TFLOPS than the FP32 comparison suggests.
The AMD Radeon 8040S has recorded Passmark results placing it at the 17th percentile among all GPUs, with an average benchmark score of 2440 and nearest rivals clustered tightly around the 2422 to 2467 range. The Intel Arc Graphics 4 Xe Mobile is listed at the 50th percentile, but with no benchmark data behind that ranking, the database cannot substantiate a performance comparison.
For users prioritizing raw compute resources, the data points to the AMD Radeon 8040S. For users prioritizing power efficiency, the Intel Arc Graphics 4 Xe Mobile's 25 W TDP is the lower figure. Without recorded benchmarks for the Intel part, the performance relationship between the two remains unresolved in the database.
