Intel Arc Graphics 128EU Mobile vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no completed benchmark runs for either Intel Arc Graphics 128EU Mobile or Intel Arc Graphics 2 Xe Mobile. Both entries show an average benchmark score of zero, and the head-to-head comparison table is empty. Consequently, there are no measured performance deltas, no percentile shifts, and no wins recorded for either part. The absence of data means any quantitative comparison of frame rates, compute throughput, or real-world application performance cannot be drawn from the database at this time.

What can be stated from the specification sheets is the theoretical peak throughput. The 128EU Mobile part lists FP32 performance of 4.608 TFLOPS, while the 2 Xe Mobile part lists 1,280.0 GFLOPS, which is 1.280 TFLOPS. That places the 128EU variant at approximately 3.6 times the raw FP32 figure of the smaller part. Similarly, the pixel rate for the 128EU is 72.00 GPixel/s versus 20.00 GPixel/s for the 2 Xe, a 3.6x difference. Texture rate shows 144.0 GTexel/s against 40.00 GTexel/s, again a 3.6x gap. These are theoretical limits, not measured outcomes, but they indicate the architectural ceiling of each chip.

Both parts sit at the 50th percentile among all GPUs in the database, which is a neutral placement. With no rival scores or percentile deltas provided, no further relative positioning is possible.

Architecture Differences

The two integrated GPUs come from different chip generations and microarchitectures. The Intel Arc Graphics 128EU Mobile is built on the Meteor Lake chip and uses the Xe-LPG architecture. The Intel Arc Graphics 2 Xe Mobile is built on the Wildcat Lake chip and uses the Xe3-LPG architecture. This is a two-generation architectural jump from Xe-LPG to Xe3-LPG.

The process node differs substantially. The 128EU uses a 10 nm node, while the 2 Xe uses a 3 nm node. Both are fabricated by Intel, but the 3 nm process allows for a denser transistor layout and lower power per transistor, which helps explain the higher boost clock of 2500 MHz on the smaller part despite its lower TDP of 25 W.

The execution resource configuration is dramatically different. The 128EU packs 1024 shading units, 64 texture mapping units, and 32 ROPs. The 2 Xe has 256 shading units, 16 TMUs, and 8 ROPs. The 128EU has 4 times the shading units, 4 times the TMUs, and 4 times the ROPs. This directly scales the theoretical pixel rate, texture rate, and FP32 throughput.

The 2 Xe introduces dedicated ray tracing hardware with 2 RT cores. The 128EU does not list any RT cores. Furthermore, the API support reflects this: the 2 Xe supports DirectX 12 Ultimate (12_2), which includes features such as ray tracing and mesh shaders, while the 128EU is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Memory architecture is identical in interface terms. Both use System Shared memory, with a System Shared bus width and System Dependent bandwidth. Neither has dedicated VRAM.

The bus interface differs. The 128EU uses a Ring Bus, while the 2 Xe lists IGP as its bus interface. Both are integrated graphics parts with a slot width of IGP.

The 2 Xe lists no power connectors, which is typical for an integrated part. The 128EU does not specify power connectors. Display outputs for both are Portable Device Dependent, meaning the outputs rely on the host laptop or portable device.

Both parts list their predecessor as HD Graphics-M. The 128EU is from the Arc Graphics-M (Meteor Lake) generation, and the 2 Xe is from the Arc Graphics-M (Wildcat Lake) generation. Both are currently marked as Active in production status.

Where Each One Wins

Based strictly on raw compute resources, the Intel Arc Graphics 128EU Mobile wins in every throughput category. Its 4.608 TFLOPS FP32 is 3.6 times the 1,280.0 GFLOPS of the 2 Xe. Its 72.00 GPixel/s fill rate is 3.6 times the 20.00 GPixel/s of the smaller part. Its 144.0 GTexel/s is 3.6 times the 40.00 GTexel/s. For workloads that scale with shading units, texture units, or ROPs, such as conventional rasterization, high-resolution rendering, or compute-heavy tasks, the 128EU has a clear theoretical advantage.

The Intel Arc Graphics 2 Xe Mobile wins in architectural modernity and feature support. It has a newer 3 nm process node compared to 10 nm, a higher boost clock of 2500 MHz versus 2250 MHz, and lower power draw at 25 W versus 28 W. It also includes 2 ray tracing cores, which the 128EU lacks entirely, and supports DirectX 12 Ultimate (12_2), enabling ray-traced effects and advanced DX12 features that the 128EU cannot access due to its DirectX 12 (12_1) support.

For integrated graphics in portable devices, the 2 Xe may be more efficient per watt. Its TDP is 3 W lower, and its boost clock is 250 MHz higher. However, the 128EU delivers 3.6 times the theoretical throughput. The trade-off is between feature set and raw performance.

The Verdict

The data shows two distinctly positioned integrated GPUs. The Intel Arc Graphics 128EU Mobile is the higher-throughput part, with 4 times the shading units, TMUs, and ROPs of the 2 Xe, and a 3.6x advantage in FP32, pixel rate, and texture rate. It is the choice for users prioritizing raw compute and rasterization performance in a Meteor Lake-based system.

The Intel Arc Graphics 2 Xe Mobile is the newer, more feature-complete part. It brings a 3 nm process, ray tracing cores, DirectX 12 Ultimate support, a higher boost clock, and a lower TDP. It is the choice for users who need modern graphics features and better power efficiency, even at a significant cost to raw throughput.

Given the empty benchmark results, the database cannot confirm real-world performance differences. The theoretical specifications indicate that the 128EU is far stronger in traditional GPU workloads, while the 2 Xe is ahead in architectural features and efficiency. The 128EU targets performance, the 2 Xe targets efficiency and feature support. The selection depends on which priority matters more: raw throughput or modern API capabilities.
