Intel Arc Graphics 1 Xe Mobile vs Intel Arc Graphics 128EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc Graphics 1 Xe Mobile and the Intel Arc Graphics 128EU Mobile. The benchmark database lists zero wins for either part, and the average benchmark score for both is 0. This absence of measured performance data makes a direct numerical comparison impossible from the database alone.

What the database does show is a stark contrast in raw compute specifications, which allows for theoretical throughput comparisons. The Intel Arc Graphics 128EU Mobile delivers 4.608 TFLOPS of FP32 compute, while the Intel Arc Graphics 1 Xe Mobile delivers 588.8 GFLOPS. That places the 128EU part at roughly 7.8 times the FP32 throughput of the 1 Xe part. Pixel throughput follows a similar pattern: 72.00 GPixel/s versus 9.200 GPixel/s, a factor of about 7.8. Texture rate shows 144.0 GTexel/s against 18.40 GTexel/s, again a near 7.8 times difference.

The boost clocks are close, with the 1 Xe part boosting to 2300 MHz and the 128EU part to 2250 MHz, a difference of only 50 MHz in favor of the smaller GPU. The base clocks are identical at 300 MHz. This indicates the performance gap stems almost entirely from execution resource counts rather than clock speed. The 128EU part uses 1024 shading units, 64 TMUs, and 32 ROPs, while the 1 Xe part uses 128 shading units, 8 TMUs, and 4 ROPs. Every execution resource scales by a factor of 8.

In the absence of measured game or synthetic scores, the specification-derived throughput figures are the only quantitative basis for comparison. The database assigns both parts the same 50th percentile ranking among all GPUs, which reflects the absence of benchmark entries rather than equivalent real-world performance.

Architecture Differences

The two GPUs represent different architecture generations from Intel. The Intel Arc Graphics 1 Xe Mobile uses the Xe3-LPG architecture on the Wildcat Lake chip, built on a 3 nm process. The Intel Arc Graphics 128EU Mobile uses the Xe-LPG architecture on the Meteor Lake chip, built on a 10 nm process. Both are manufactured by Intel, but the process node difference is substantial: 3 nm versus 10 nm.

The generation naming also differs. The 1 Xe part belongs to the Arc Graphics-M (Wildcat Lake) generation, while the 128EU part belongs to the Arc Graphics-M (Meteor Lake) generation. Both list HD Graphics-M as their predecessor, and neither has a recorded successor.

Feature support shows a meaningful split. The Intel Arc Graphics 1 Xe Mobile supports DirectX 12 Ultimate (12_2), while the Intel Arc Graphics 128EU Mobile supports DirectX 12 (12_1). This indicates the newer Xe3-LPG architecture carries the full DirectX 12 Ultimate feature set, including hardware ray tracing support. The database confirms this: the 1 Xe part lists 1 ray tracing core, while the 128EU part lists no ray tracing cores. OpenGL 4.6 and Vulkan 1.4 are supported by both.

The bus interface differs as well. The 1 Xe part uses an IGP interface, while the 128EU part uses a Ring Bus interface. Both are integrated graphics solutions with a slot width of IGP. The 128EU part carries a higher TDP of 28 W versus 25 W for the 1 Xe part, a 3 W difference.

Memory architecture is effectively identical in configuration: both use system shared memory with a system shared bus width and system dependent bandwidth. Neither has dedicated VRAM. The display outputs are portable device dependent for both. Power connectors are listed as none for the 1 Xe part, while the 128EU part has no connector data recorded.

Where Each One Wins

The Intel Arc Graphics 128EU Mobile wins decisively on raw computational throughput. Its 4.608 TFLOPS FP32 performance, 72.00 GPixel/s pixel rate, and 144.0 GTexel/s texture rate represent roughly 7.8 times the corresponding figures of the Intel Arc Graphics 1 Xe Mobile. For any workload that scales with shader count, texture units, or ROPs, the 128EU part holds a commanding advantage. The 1024 shading units versus 128, 64 TMUs versus 8, and 32 ROPs versus 4 make this a substantially more capable compute device.

The Intel Arc Graphics 1 Xe Mobile wins on architectural modernity and efficiency per watt. The 3 nm process node versus 10 nm gives it a significant manufacturing advantage. It also carries the Xe3-LPG architecture with DirectX 12 Ultimate (12_2) support and 1 ray tracing core, features absent from the 128EU part. The 1 Xe part operates at a lower 25 W TDP while boosting 50 MHz higher (2300 MHz versus 2250 MHz). For ray tracing workloads, the 1 Xe part has hardware support that the 128EU part lacks entirely.

The boost clock advantage, though small, favors the 1 Xe part. The 50 MHz difference suggests the newer architecture can reach slightly higher frequencies despite the lower TDP. This could benefit lightly threaded or latency-sensitive workloads where clock speed matters more than raw throughput. The identical base clock of 300 MHz means both parts idle at the same frequency.

In terms of API support, the 1 Xe part offers the more complete DirectX feature set with 12 Ultimate (12_2). The 128EU part stops at DirectX 12 (12_1). Games or applications that require DirectX 12 Ultimate features, particularly hardware ray tracing, would only run on the 1 Xe part. The 128EU part would need to fall back to software or alternative rendering paths.

FAQ

The Verdict

The database paints a clear split between two very different design philosophies. The Intel Arc Graphics 128EU Mobile is the throughput leader by a wide margin. Its 1024 shading units, 64 TMUs, and 32 ROPs deliver 4.608 TFLOPS FP32, 144.0 GTexel/s, and 72.00 GPixel/s. Any workload that stresses traditional rasterization or general compute will favor this part decisively. The 28 W TDP reflects the cost of that extra execution hardware.

The Intel Arc Graphics 1 Xe Mobile is the architectural leader. The Xe3-LPG architecture on a 3 nm process represents a newer generation with DirectX 12 Ultimate (12_2) support and a hardware ray tracing core. The 128EU part has no ray tracing hardware and stops at DirectX 12 (12_1). The 1 Xe part also boosts 50 MHz higher at a lower 25 W TDP, indicating better frequency efficiency from the newer process node.

Users who prioritize maximum shader throughput, texture fill, or pixel fill should choose the Intel Arc Graphics 128EU Mobile. Users who need DirectX 12 Ultimate features, hardware ray tracing, or the efficiency of a newer architecture on a smaller process node should choose the Intel Arc Graphics 1 Xe Mobile. The data does not support a single winner because the two parts target different capability sets. The 128EU part is the compute powerhouse; the 1 Xe part is the feature-forward design.
