Intel Arc Graphics 2 Xe Mobile vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the Intel Arc Graphics 2 Xe Mobile against the Intel Arc Graphics 4 Xe Mobile. Both entries list an average benchmark score of 0 and a percentile ranking of 50 against all GPUs. The absence of measured scores means the comparison must rely on the specification data, which shows a clear performance hierarchy based on compute resources.

The Arc Graphics 4 Xe Mobile doubles the shading units, texture mapping units, and render output units of the Arc Graphics 2 Xe Mobile. The 4 Xe configuration delivers 2.355 TFLOPS of FP32 throughput, while the 2 Xe configuration delivers 1,280.0 GFLOPS. That is an 84% advantage in raw floating-point compute for the larger part. The texture rate follows the same pattern: 73.60 GTexel/s versus 40.00 GTexel/s, an 84% lead. Pixel rate shows a smaller gap at 36.80 GPixel/s versus 20.00 GPixel/s, which is still a substantial 84% advantage.

Clock speeds tell a different story. The Arc Graphics 2 Xe Mobile boosts to 2500 MHz, while the Arc Graphics 4 Xe Mobile boosts to 2300 MHz. The smaller GPU runs 200 MHz higher at peak boost, yet the doubled execution resources of the 4 Xe part overwhelm that frequency advantage. The 2 Xe part's higher boost clock cannot compensate for having half the shading units, TMUs, and ROPs.

Both GPUs use system-shared memory with system-dependent bandwidth. Memory size, type, and bus width are all listed as system shared, meaning the actual memory performance depends entirely on the host platform rather than the GPU itself. The data does not assign a specific memory bandwidth figure to either part.

The FP16 throughput scales proportionally with FP32. The 2 Xe part reaches 2.560 TFLOPS with a 2:1 ratio, while the 4 Xe part reaches 4.710 TFLOPS. This confirms the compute ratio holds across precision formats.

The ray tracing core count also doubles: 2 RT cores on the 2 Xe part versus 4 RT cores on the 4 Xe part. Since no ray tracing benchmarks are recorded, the data can only confirm the resource allocation difference, not the realized performance delta in ray-traced workloads.

Architecture Differences

Both GPUs share the Xe3-LPG architecture, indicating a common design generation. The manufacturing process is identical at 3 nm, and both are fabricated by Intel. The transistor count and die size are listed as unknown for both, so no comparison can be made on implementation scale.

The chip names differ. The Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip, while the Arc Graphics 4 Xe Mobile uses the Panther Lake chip. This places them in different product families within the same generation: Arc Graphics-M (Wildcat Lake) versus Arc Graphics-M (Panther Lake).

The execution resource configuration is the primary architectural differentiator. The 2 Xe part has 256 shading units, 16 TMUs, 8 ROPs, and 2 RT cores. The 4 Xe part doubles each of these: 512 shading units, 32 TMUs, 16 ROPs, and 4 RT cores. Doubling all four resource categories simultaneously creates a balanced scaling pattern, meaning the 4 Xe part is not skewed toward one type of workload; it scales geometry processing, texture filtering, pixel output, and ray intersection work proportionally.

The base clocks are identical at 300 MHz. The boost clocks diverge, with the 2 Xe part reaching 2500 MHz and the 4 Xe part reaching 2300 MHz. The architecture analysis suggests the 4 Xe part's lower boost clock may reflect power or thermal constraints from activating twice the execution hardware, though the recorded data does not specify the reason.

Both GPUs are integrated graphics parts with an IGP slot width, no power connectors, and portable-device-dependent display outputs. Neither has a dedicated memory interface; both rely on system shared memory.

Specification Differences

The two GPUs differ in the following recorded specifications:

• Shading units: 256 on the 2 Xe part, 512 on the 4 Xe part
• TMUs: 16 on the 2 Xe part, 32 on the 4 Xe part
• ROPs: 8 on the 2 Xe part, 16 on the 4 Xe part

• FP32 compute: 1,280.0 GFLOPS on the 2 Xe part, 2.355 TFLOPS on the 4 Xe part
• FP16 compute: 2.560 TFLOPS on the 2 Xe part, 4.710 TFLOPS on the 4 Xe part
• Chip: Wildcat Lake on the 2 Xe part, Panther Lake on the 4 Xe part

• Predecessor: HD Graphics-M for the 2 Xe part, none listed for the 4 Xe part

Identical specifications include the 3 nm process node, Intel foundry, Xe3-LPG architecture, 300 MHz base clock, 25 W TDP, IGP slot width, no power connectors, system-shared memory, DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4, and active production status. Both lack a launch MSRP in the database.

Where Each One Wins

The Intel Arc Graphics 4 Xe Mobile wins in every compute throughput category recorded. Its FP32 rate of 2.355 TFLOPS exceeds the 1,280.0 GFLOPS of the 2 Xe part by 84%. Texture filtering follows the same ratio at 73.60 GTexel/s versus 40.00 GTexel/s. Pixel throughput favors the 4 Xe part at 36.80 GPixel/s versus 20.00 GPixel/s. Ray tracing hardware also favors the 4 Xe part with 4 RT cores versus 2 RT cores. For any workload that scales with shading units, texture units, ROPs, or RT cores, the data points to the 4 Xe configuration as the stronger option.

The Intel Arc Graphics 2 Xe Mobile wins in one recorded metric: boost clock. At 2500 MHz, it runs 200 MHz higher than the 2300 MHz of the 4 Xe part. This could benefit lightly threaded or latency-sensitive workloads where single-core GPU frequency matters more than raw throughput, though the database records no benchmark to confirm this. The 2 Xe part also has an earlier predecessor lineage, with HD Graphics-M listed, while the 4 Xe part has no predecessor recorded. This suggests the 2 Xe part inherits a longer product history, but that is a product genealogy fact rather than a performance advantage.

The power envelope is identical at 25 W for both. The 4 Xe part delivers double the compute resources within the same TDP, which makes it the more efficient configuration per watt available in the recorded data. The 2 Xe part's higher boost clock within the same power limit indicates it may be tuned for a different operating point, but the database does not include measured power efficiency numbers.

The release dates place the 4 Xe part earlier: 2026-01-26 versus 2026-04-15 for the 2 Xe part. The 2 Xe part arrived roughly three months later in the recorded timeline.

The Verdict

The recorded data supports a straightforward selection criterion. The Intel Arc Graphics 4 Xe Mobile is the higher-performing part across every measured throughput metric. It doubles the shading units, TMUs, ROPs, and RT cores, resulting in 84% higher FP32 compute, 84% higher texture rate, and 84% higher pixel rate, all within the same 25 W TDP. The 4 Xe part also arrived earlier in the product timeline, launching in January 2026 versus April 2026 for the 2 Xe part.

The only specification where the 2 Xe part leads is the boost clock: 2500 MHz versus 2300 MHz. This 200 MHz advantage does not translate into any recorded benchmark win, and the throughput calculations show the 4 Xe part holds a decisive lead in aggregate compute. The 2 Xe part's higher frequency may benefit workloads that are sensitive to clock speed rather than parallel throughput, but no measured data confirms this behavior.

The Intel Arc Graphics 2 Xe Mobile suits scenarios where the 25 W power envelope matters and the workload does not require the full execution resource set. Its 256 shading units and 2 RT cores handle lighter graphics tasks, while its higher boost clock could offer responsiveness in clock-bound scenarios. The predecessor lineage from HD Graphics-M suggests continuity with prior integrated graphics, which may matter for platforms with established driver or compatibility expectations.

The Intel Arc Graphics 4 Xe Mobile suits scenarios where maximum throughput per watt is the goal. With 512 shading units, 4 RT cores, and 2.355 TFLOPS FP32, it provides the strongest recorded compute capability in this comparison. The identical 25 W TDP means the 4 Xe part delivers fundamentally more work per unit of power. Its earlier release date also indicates it is the more established product in the database timeline.

The data does not include benchmark scores, so the verdict rests on the specification deltas. The 4 Xe part is the clear choice for compute-heavy graphics workloads, ray tracing, and higher resolution rendering. The 2 Xe part is the choice for platforms that value the higher boost clock and smaller execution resource footprint. For any user deciding between the two purely on recorded performance capability, the 4 Xe Mobile's doubled resources and 84% throughput advantage make it the stronger part.
