Intel Arc G3 vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark entries for these two integrated graphics processors. Both units share the same Panther Lake chip and Xe3-LPG architecture, and the database lists no direct comparison scores, no average benchmark scores, and no wins for either part. The percentile placement for both is identical at 50, indicating they sit at the median of all GPUs in the database, but this is not a comparative measurement between the two.

Without direct benchmark results, the closest quantitative comparison comes from the theoretical throughput figures recorded in their specifications. The Intel Arc G3 delivers 6.144 TFLOPS of FP32 compute, while the Intel Arc Graphics 4 Xe Mobile delivers 2.355 TFLOPS. That places the G3 at approximately 2.6 times the raw shader throughput of the 4 Xe Mobile part. In FP16 with 2:1 ratio, the G3 reaches 12.29 TFLOPS versus 4.710 TFLOPS for the 4 Xe Mobile, maintaining the same ratio.

Pixel throughput differences are smaller but still meaningful. The G3 outputs 48.00 GPixel/s, while the 4 Xe Mobile outputs 36.80 GPixel/s. Texture rate shows a similar gap: 96.00 GTexel/s for the G3 versus 73.60 GTexel/s for the 4 Xe Mobile. These figures reflect the ROP and TMU counts, which differ less dramatically than the shading unit counts.

The boost clocks differ modestly: 2400 MHz for the G3 versus 2300 MHz for the 4 Xe Mobile. Both share a 300 MHz base clock. The G3 also carries 1280 shading units against 512 for the 4 Xe Mobile, a 2.5 times advantage. Ray tracing cores follow a similar pattern with 10 RT cores on the G3 versus 4 on the 4 Xe Mobile.

Because the database records no benchmark wins for either part, the head-to-head section must rely on these specification-derived throughput numbers. The G3 wins decisively in every measured compute and rasterization metric. The 4 Xe Mobile does not win any recorded specification comparison, though its lower resource counts mean it likely consumes similar power at a lower performance envelope, as both are rated at 25 W TDP.

Architecture Differences

Both processors come from the same Panther Lake chip and use the Xe3-LPG architecture, built on Intel's 3 nm process node at Intel's own foundry. The generation is identical: Arc Graphics-M (Panther Lake). Neither part has a listed codename, predecessor, or successor in the database.

The core configuration is where the two diverge. The Intel Arc G3 uses 1280 shading units, 40 texture mapping units, and 20 raster operation units. The Intel Arc Graphics 4 Xe Mobile uses 512 shading units, 32 TMUs, and 16 ROPs. The G3 has 10 ray tracing cores, while the 4 Xe Mobile has 4. Neither part lists tensor cores, so AI acceleration hardware is absent from both.

Both processors use system shared memory with a system shared bus width and system dependent bandwidth. Memory type and size are also system shared for both. The G3 boosts to 2400 MHz, the 4 Xe Mobile to 2300 MHz, with both starting at 300 MHz base.

The process node, foundry, and architecture are identical, meaning the performance gap comes purely from execution unit counts and clock speed. The G3 runs 100 MHz higher boost, but the larger difference is the 2.5 times shading unit advantage. Transistor count and die size are listed as unknown for both, so no comparison is possible there.

Both parts expose the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are portable device dependent for both, and both use an IGP slot width with no power connectors. The TDP is 25 W for each.

The release dates differ. The 4 Xe Mobile launched earlier, with a release date recorded as 2026-01-26, while the G3 has a release date of 2026-05-31. Both are listed as active production status.

Where Each One Wins

The Intel Arc G3 wins every specification comparison where a difference exists. Its 6.144 TFLOPS FP32 throughput is 2.6 times the 4 Xe Mobile's 2.355 TFLOPS. Pixel rate favors the G3 at 48.00 GPixel/s versus 36.80 GPixel/s, a 30% advantage. Texture rate favors the G3 at 96.00 GTexel/s versus 73.60 GTexel/s, a 30% advantage as well. The shading unit count of 1280 versus 512 gives the G3 a clear edge in any workload that scales with shader execution width.

The G3 also carries 10 RT cores versus 4, so ray tracing workloads that use these dedicated units will see a substantial difference. The higher boost clock of 2400 MHz versus 2300 MHz adds a small additional edge to the G3.

The 4 Xe Mobile wins no recorded comparison. Its lower resource counts mean it produces less heat and likely runs cooler in a thin chassis, but the database records no thermal measurements. Both parts share the same 25 W TDP, so power draw is not a differentiator in the recorded data.

For use cases, the G3 suits workloads that exercise raw compute: shader-heavy rendering, FP32 compute tasks, and ray-traced scenes. The 4 Xe Mobile fits lighter duties where the lower execution unit count is sufficient, such as basic desktop compositing or older games, though the database provides no direct game benchmarks to confirm this.

The 30% pixel rate and texture rate advantages for the G3 indicate it handles fill-rate-bound scenarios better, which matters for high-resolution rendering. The 4 Xe Mobile's smaller configuration may be adequate for lower resolutions or less demanding titles.

• Shading units: 1280 versus 512
• Texture mapping units: 40 versus 32

All other recorded specifications are identical: 3 nm process node, Intel foundry, Xe3-LPG architecture, Panther Lake chip, 300 MHz base clock, system shared memory, 25 W TDP, IGP slot width, no power connectors, portable device dependent display outputs, and the same API set.

The Verdict

The data indicates a clear performance hierarchy. The Intel Arc G3 is the stronger part in every measurable specification: 2.6 times the FP32 throughput, 2.5 times the shading units, 2.5 times the ray tracing cores, 30% higher pixel rate, and 30% higher texture rate. The 4 Xe Mobile offers no advantage in any recorded field.

For a user selecting between these two integrated graphics options, the G3 is the choice whenever compute performance matters. Its higher shader count and RT core count make it suitable for more demanding visual workloads, including ray-traced content and high-resolution rendering. The 4 Xe Mobile, with its lower resource counts, fits scenarios where the lighter configuration is sufficient, though the database records no specific workload where it outperforms the G3.

Both parts share the same 25 W TDP, so the G3 delivers substantially more performance within the same power envelope. The 4 Xe Mobile's earlier release date may matter for platform availability, but from a pure performance standpoint, the G3 dominates. The identical architecture and process node mean the G3's advantage comes from more execution resources and a slightly higher boost clock, not from a more efficient design.

The database shows no benchmark scores for either part, so real-world application performance cannot be quantified beyond the theoretical rates. However, the specification-derived figures point to one conclusion: the Intel Arc G3 is the higher-performing integrated GPU, and the Intel Arc Graphics 4 Xe Mobile is a more modest configuration for lighter use.
