Intel Arc G3 vs Intel Arc Graphics 64EU Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the Intel Arc G3 and the Intel Arc Graphics 64EU Mobile. Both entries show zero benchmark scores and zero wins in their respective categories. The absence of measured data means a direct performance comparison cannot be established through empirical testing results.

What can be compared are the theoretical throughput figures derived from each chip's architecture. The Intel Arc G3 delivers 6.144 TFLOPS of FP32 compute, while the Intel Arc Graphics 64EU Mobile delivers 1.792 TFLOPS. This represents a 3.4x advantage for the Arc G3 in raw floating-point throughput. The FP16 figures follow the same pattern, with the Arc G3 achieving 12.29 TFLOPS against 3.584 TFLOPS for the 64EU Mobile, again a 3.4x difference.

Pixel throughput shows a smaller but still substantial gap. The Arc G3 renders at 48.00 GPixel/s, while the 64EU Mobile achieves 28.00 GPixel/s, giving the Arc G3 a 1.7x lead. Texture fill rates stand at 96.00 GTexel/s for the Arc G3 and 56.00 GTexel/s for the 64EU Mobile, a 1.7x difference as well.

These figures indicate that the Arc G3 is positioned significantly above the 64EU Mobile in raw compute capacity. The shading unit count supports this, with the Arc G3 featuring 1280 shading units against 512 for the 64EU Mobile, a 2.5x difference. The Arc G3 also carries 40 texture mapping units and 20 raster output units, compared to 32 and 16 respectively on the 64EU Mobile.

Where Each One Wins

The Intel Arc G3 wins in every measurable compute category within the database. Its FP32 throughput of 6.144 TFLOPS positions it well above the 64EU Mobile's 1.792 TFLOPS. Applications that rely on heavy shader workloads, such as modern game rendering or GPU-accelerated compute tasks, would benefit from the Arc G3's larger shading unit count of 1280 versus 512.

The Arc G3 also holds a clear advantage in ray tracing, as the database lists 10 dedicated RT cores for this part. The 64EU Mobile has no RT cores listed. This makes the Arc G3 the only one of the two capable of hardware-accelerated ray tracing, a meaningful distinction for games and rendering workloads that use this feature.

The 64EU Mobile's advantage lies elsewhere. Its thermal design power is 65 W, which is higher than the Arc G3's 25 W. On paper, this gives the 64EU Mobile more headroom for sustained operation in a mobile chassis, though the Arc G3's lower power draw suggests it could fit into thinner or more power-constrained designs. The 64EU Mobile uses a Ring Bus interface, while the Arc G3 uses an IGP bus interface, which may affect integration options in different system layouts.

For memory, both parts use System Shared memory with System Dependent bandwidth, so there is no distinction in memory capacity or type. The Arc G3's boost clock of 2400 MHz exceeds the 64EU Mobile's 1750 MHz, reinforcing its compute advantage. The base clocks are identical at 300 MHz.

Specification Differences

The two GPUs differ across nearly every specification field in the database. The Intel Arc G3 is built on a 3 nm process node, while the Intel Arc Graphics 64EU Mobile uses a 10 nm node. Both are manufactured by Intel, but the process difference is substantial.

Clock speeds differ significantly. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The 64EU Mobile also has a 300 MHz base clock but boosts to only 1750 MHz.

The shading unit count is 1280 for the Arc G3 versus 512 for the 64EU Mobile. Texture mapping units number 40 against 32, and raster output units number 20 against 16. The Arc G3 lists 10 RT cores, while the 64EU Mobile lists none.

Compute rates follow the architectural differences. The Arc G3 achieves 48.00 GPixel/s and 96.00 GTexel/s. The 64EU Mobile achieves 28.00 GPixel/s and 56.00 GTexel/s. FP32 performance is 6.144 TFLOPS versus 1.792 TFLOPS, and FP16 performance is 12.29 TFLOPS versus 3.584 TFLOPS.

Power ratings diverge sharply. The Arc G3 has a 25 W TDP, while the 64EU Mobile has a 65 W TDP. The Arc G3 uses an IGP bus interface, while the 64EU Mobile uses a Ring Bus interface. Neither part has a launch MSRP recorded.

The Arc G3 supports DirectX 12 Ultimate (12_2), while the 64EU Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. Display outputs are Portable Device Dependent for both.

The release dates differ by roughly two and a half years. The 64EU Mobile was released on 2023-12-13, while the Arc G3 was released on 2026-05-31. The 64EU Mobile lists a predecessor, HD Graphics-M, while the Arc G3 has no predecessor recorded.

Architecture Differences

The Intel Arc G3 uses the Panther Lake chip with the Xe3-LPG architecture, part of the Arc Graphics-M generation for Panther Lake. The Intel Arc Graphics 64EU Mobile uses the Meteor Lake chip with the Xe-LPG architecture, part of the Arc Graphics-M generation for Meteor Lake. These are different generations of Intel's integrated GPU designs.

The process node is a major differentiator. The Arc G3 is fabricated on a 3 nm process, while the 64EU Mobile uses a 10 nm process. This node difference explains part of the power and efficiency gap, with the Arc G3 rated at 25 W versus 65 W for the 64EU Mobile.

The Arc G3 includes 10 RT cores, a feature absent from the 64EU Mobile's specifications. This indicates a hardware-level capability for ray tracing that the older part lacks entirely.

Shader organization differs as well. The Arc G3 packs 1280 shading units into its Xe3-LPG design, while the 64EU Mobile's Xe-LPG design contains 512. The texture and raster pipeline also scales differently, with the Arc G3 carrying 40 TMUs and 20 ROPs against 32 and 16 for the 64EU Mobile.

The API support reflects the newer architecture. The Arc G3 reaches DirectX 12 Ultimate (12_2), which includes features like mesh shaders and variable rate shading. The 64EU Mobile tops out at DirectX 12 (12_1), missing some of the Ultimate feature set. Both support OpenGL 4.6 and Vulkan 1.4.

Memory architecture is identical in description: both use System Shared memory with System Dependent bandwidth. Neither has dedicated VRAM, so both rely on the host system's memory subsystem.

The bus interfaces differ, with the Arc G3 using IGP and the 64EU Mobile using Ring Bus. This suggests different integration approaches in their respective mobile platforms.

The Verdict

The data shows a clear performance hierarchy. The Intel Arc G3 outperforms the Intel Arc Graphics 64EU Mobile across every compute metric recorded. Its FP32 throughput of 6.144 TFLOPS is 3.4x higher, its pixel rate of 48.00 GPixel/s is 1.7x higher, and its texture rate of 96.00 GTexel/s is 1.7x higher. The shading unit count of 1280 versus 512 reinforces this gap.

The Arc G3 is the only one of the two with ray tracing hardware, listing 10 RT cores. This makes it the better choice for workloads that use DirectX 12 Ultimate features, which the Arc G3 supports through its 12_2 API level. The 64EU Mobile's DirectX 12 (12_1) support limits its feature set in this regard.

The Arc G3 also delivers this higher performance at a lower TDP, 25 W versus 65 W. This efficiency advantage comes from its 3 nm process node compared to the 64EU Mobile's 10 nm node. Systems using the Arc G3 could potentially be thinner, lighter, or have longer battery life while offering more compute capability.

The 64EU Mobile does have one distinguishing characteristic: its Ring Bus interface and its higher 65 W TDP. In a system designed around that power envelope, it might sustain its lower performance level consistently. But the measured specifications give no category where the 64EU Mobile beats the Arc G3.

For any use case involving modern graphics, compute, or ray tracing, the Arc G3 is the stronger part based on the database records. The 64EU Mobile remains a functional integrated GPU for basic tasks, but its older architecture, lower clocks, and absence of RT cores place it firmly below the Arc G3 in capability. The choice between them, strictly from the data, favors the Arc G3.
