Intel Arc Graphics 4 Xe Mobile vs Intel Iris Xe Graphics 80EU Mobile Comparison

The Verdict

The data positions Intel Arc Graphics 4 Xe Mobile as the newer, more capable integrated solution while Intel Iris Xe Graphics 80EU Mobile remains a solid older option. The Arc Graphics 4 Xe Mobile, built on Panther Lake with the Xe3-LPG architecture, delivers higher clock speeds, more advanced API support, and superior raw throughput metrics. The Iris Xe Graphics 80EU Mobile, based on Raptor Lake with Generation 12.2 architecture, counters with a larger shader count and higher texture unit count, but its lower boost clock and older feature set place it behind in most measurable performance categories.

For users prioritizing modern graphics features and higher computational throughput, the Arc Graphics 4 Xe Mobile is the clear choice. For those already on Raptor Lake platforms where the Iris Xe Graphics 80EU is integrated, the data shows it remains a functional option with 640 shading units and a 15 W power envelope, though it lags in peak clock speed and API compatibility.

Architecture Differences

The fundamental architectural split between these two Intel integrated GPUs is stark. The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on a 3 nm process node, while the Intel Iris Xe Graphics 80EU Mobile uses Generation 12.2 on a 10 nm process node. Both are fabricated by Intel, but the process node difference alone explains much of the performance gap. The 3 nm node enables higher clock speeds at lower power consumption, while the 10 nm node is an older, more mature process.

The chip-level differences are equally significant. The Arc Graphics 4 Xe Mobile is built on the Panther Lake chip, while the Iris Xe Graphics 80EU Mobile uses the Raptor Lake chip. The generations differ: Arc Graphics-M (Panther Lake) versus HD Graphics-M (Raptor Lake). The newer architecture brings support for DirectX 12 Ultimate (12_2), whereas the older Iris Xe only supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so those API levels are shared.

Ray tracing support is another key differentiator. The Arc Graphics 4 Xe Mobile includes 4 dedicated RT cores, while the Iris Xe Graphics 80EU Mobile has no RT cores listed. This means hardware-accelerated ray tracing is only available on the newer part. The bus interface also differs: the Arc Graphics 4 Xe Mobile uses IGP, while the Iris Xe Graphics 80EU Mobile uses Ring Bus.

The production status for both is Active, but the release dates are far apart. The Iris Xe Graphics 80EU Mobile launched on 2023-01-03, while the Arc Graphics 4 Xe Mobile launched on 2026-01-26. The Iris Xe Graphics 80EU Mobile lists its successor as Arc Graphics-M, confirming the newer part replaces it in the product stack.

Head-to-Head Benchmarks

Direct comparison of the recorded data shows the Arc Graphics 4 Xe Mobile holds a decisive advantage in clock speed. Its boost clock reaches 2300 MHz, while the Iris Xe Graphics 80EU Mobile peaks at 1450 MHz. That is a 850 MHz difference in favor of the newer part. Both share a 300 MHz base clock, so the gap only widens under load.

The pixel rate data confirms the Arc Graphics 4 Xe Mobile delivers 36.80 GPixel/s versus 29.00 GPixel/s for the Iris Xe Graphics 80EU Mobile. That puts the newer part roughly 27% ahead in pixel throughput. The texture rate follows the same pattern: 73.60 GTexel/s for the Arc Graphics 4 Xe Mobile versus 58.00 GTexel/s for the Iris Xe Graphics 80EU Mobile, a 27% advantage.

Compute performance shows a similar story. The Arc Graphics 4 Xe Mobile achieves 2.355 TFLOPS in FP32, while the Iris Xe Graphics 80EU Mobile reaches 1.856 TFLOPS. The newer part is roughly 27% faster in single-precision compute. In FP16, the Arc Graphics 4 Xe Mobile delivers 4.710 TFLOPS (2:1) versus 3.712 TFLOPS (2:1) for the older part, maintaining the same 27% lead.

The shading unit counts tell a different tale. The Iris Xe Graphics 80EU Mobile has 640 shading units, while the Arc Graphics 4 Xe Mobile has 512. Similarly, the Iris Xe has 40 texture mapping units versus 32 for the Arc, and 20 ROPs versus 16. Despite having fewer units, the Arc Graphics 4 Xe Mobile still wins on throughput because its higher clock speed compensates for the lower unit count. The data shows clock speed matters more here than raw unit counts.

Power consumption is another point of divergence. The Arc Graphics 4 Xe Mobile is rated at 25 W, while the Iris Xe Graphics 80EU Mobile is rated at 15 W. The newer part uses more power but delivers higher performance, a trade-off that reflects its more capable architecture.

Specification Differences

The two GPUs differ across nearly every measurable specification, though some fields are shared. Both use System Shared memory with System Dependent bandwidth, and both are portable device dependent for display outputs. Neither has a suggested PSU, and both are IGP slot width with no dedicated dimensions listed.
