Intel Arc G3 vs Intel Arc Graphics 48EU Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the Intel Arc G3 versus the Intel Arc Graphics 48EU Mobile. Both parts share the same percentile ranking against all GPUs in the database, sitting at the 50th percentile, and neither has an average benchmark score or nearest rival entries populated. The absence of measured scores means the comparison must rely on the architectural and specification data recorded for each part.

The most decisive gap between the two lies in raw compute throughput. The Intel Arc G3 is recorded with an FP32 performance of 6.144 TFLOPS, while the Intel Arc Graphics 48EU Mobile delivers 1,382.4 GFLOPS, which converts to 1.3824 TFLOPS. The G3 therefore provides approximately 4.4 times the single-precision floating-point throughput of the 48EU part. That is the largest single-metric advantage in the entire comparison.

The gap persists in texture and pixel processing. The Arc G3 posts a texture rate of 96.00 GTexel/s, compared to 43.20 GTexel/s for the 48EU Mobile, a 2.22 times advantage. Pixel throughput tells a similar story: the G3 reaches 48.00 GPixel/s, while the 48EU Mobile manages 14.40 GPixel/s, a 3.33 times difference. These figures indicate that the G3 can sustain substantially higher fill rates, which directly influences resolution scaling and render target throughput.

Memory performance is not directly comparable from the recorded data. Both parts use system shared memory, with the same memory type and bus width entries, and both list bandwidth as system dependent. Neither part has a dedicated memory clock, and both show a base clock of 300 MHz. The boost clocks diverge significantly: the G3 boosts to 2400 MHz, while the 48EU Mobile boosts to 1800 MHz. That 600 MHz difference in boost frequency contributes to the compute and fill rate gaps noted above.

The shading resource counts reinforce the compute delta. The Arc G3 contains 1280 shading units, 40 texture mapping units, and 20 ROPs. The Arc Graphics 48EU Mobile contains 384 shading units, 24 TMUs, and 8 ROPs. The G3 has 3.33 times the shading units, 1.67 times the TMUs, and 2.5 times the ROPs of the 48EU part. The G3 also includes 10 ray tracing cores, while the 48EU Mobile records no ray tracing core count.

Power envelopes move in the opposite direction. The Arc G3 is rated at 25 W, while the Arc Graphics 48EU Mobile is rated at 28 W. The 48EU Mobile draws 3 W more according to the recorded TDP, despite delivering far lower compute throughput. This indicates a substantial efficiency difference per watt, though the database does not include any measured performance-per-watt benchmarks to quantify it directly.

Where Each One Wins

The Intel Arc G3 wins on every recorded performance metric. Its FP32 throughput, FP16 throughput, texture rate, and pixel rate all exceed the 48EU Mobile by wide margins. The FP16 figure is particularly telling: the G3 reaches 12.29 TFLOPS with a 2:1 ratio, while the 48EU Mobile reaches 2.765 TFLOPS with the same 2:1 ratio, a 4.44 times advantage. Applications that leverage FP16 math for shader workloads, machine learning inference, or image processing will see outsized gains from the G3.

The G3 also wins on API feature support. It is recorded with DirectX 12 Ultimate (12_2), while the 48EU Mobile is limited to DirectX 12 (12_1). This difference matters for games and applications that rely on DirectX 12 Ultimate features such as ray tracing, mesh shaders, and variable rate shading. The G3's 10 ray tracing cores provide hardware acceleration for ray-traced effects, which the 48EU Mobile lacks entirely in the recorded data.

The 48EU Mobile does hold advantages in two areas. First, it has a lower TDP at 28 W versus 25 W, but that is not a win in the traditional sense; it is actually a higher power draw. The real advantage for the 48EU Mobile is its bus interface: it uses a Ring Bus, whereas the G3 uses IGP. The Ring Bus configuration may integrate differently with the host processor's memory subsystem, though the database records both parts as system shared memory designs with system dependent bandwidth. Second, the 48EU Mobile has a predecessor listed as HD Graphics-M, indicating a longer lineage in Intel's mobile graphics lineup, while the G3 has no predecessor recorded.

The release timing also favors the 48EU Mobile in terms of maturity. The 48EU Mobile was released on 2023-12-13, while the Arc G3 is dated 2026-05-31. That places the 48EU Mobile over two years earlier in the release timeline, suggesting it has had more time in the field, though the database records both as active production status.

Specification Differences

The two GPUs differ across nearly every recorded specification. The process node is the most fundamental divergence: the Intel Arc G3 uses a 3 nm process, while the Intel Arc Graphics 48EU Mobile uses a 10 nm process. Both are fabricated by Intel.

The chip and architecture also differ. The G3 is based on the Panther Lake chip with the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. The 48EU Mobile is based on the Meteor Lake chip with the Xe-LPG architecture, part of the Arc Graphics-M (Meteor Lake) generation.

Compute resources differ substantially. The G3 has 1280 shading units, 40 TMUs, and 20 ROPs. The 48EU Mobile has 384 shading units, 24 TMUs, and 8 ROPs. The G3 adds 10 ray tracing cores, while the 48EU Mobile has none recorded.

Clock speeds differ only at boost: the G3 runs at 300 MHz base and 2400 MHz boost, while the 48EU Mobile runs at 300 MHz base and 1800 MHz boost. Both use system shared memory with system dependent bandwidth.

Output rates differ as follows: the G3 produces 48.00 GPixel/s and 96.00 GTexel/s, while the 48EU Mobile produces 14.40 GPixel/s and 43.20 GTexel/s. FP32 output is 6.144 TFLOPS for the G3 versus 1,382.4 GFLOPS for the 48EU Mobile. FP16 output is 12.29 TFLOPS for the G3 versus 2.765 TFLOPS for the 48EU Mobile, both at a 2:1 ratio.

The TDP differs by 3 W, with the G3 at 25 W and the 48EU Mobile at 28 W. The bus interface differs: the G3 uses IGP, while the 48EU Mobile uses Ring Bus. Both use IGP slot width, neither has a power connector recorded, and both have display outputs listed as portable device dependent.

API support differs in DirectX only. The G3 supports DirectX 12 Ultimate (12_2), while the 48EU Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Release dates differ by roughly two and a half years. The 48EU Mobile launched on 2023-12-13, while the G3 is dated 2026-05-31. The 48EU Mobile lists HD Graphics-M as its predecessor; the G3 has no predecessor recorded.

Architecture Differences

The architectural split between the two parts is generational. The Intel Arc G3 uses the Xe3-LPG architecture, while the Intel Arc Graphics 48EU Mobile uses the older Xe-LPG architecture. This is not a minor revision; it is a full architecture generation change within Intel's graphics lineup.

The process node difference reinforces the generational gap. The G3 is built on a 3 nm process, whereas the 48EU Mobile uses a 10 nm process. The smaller node allows the G3 to pack 1280 shading units into a 25 W envelope, while the 48EU Mobile manages only 384 shading units within a 28 W envelope on the larger node. The density improvement is evident in the compute ratios, even though the database records no transistor counts or die sizes for either part.

The chip designs reflect different platform targets. The G3 pairs with Panther Lake, a platform that corresponds to the newer Arc Graphics-M generation. The 48EU Mobile pairs with Meteor Lake, the earlier generation. The bus interface difference, IGP for the G3 versus Ring Bus for the 48EU Mobile, indicates different integration paths into the host processor.

The G3's hardware ray tracing capability is the most significant architectural feature absent from the 48EU Mobile. The G3 records 10 ray tracing cores, enabling DirectX 12 Ultimate features. The 48EU Mobile has no ray tracing cores and is capped at DirectX 12 (12_1), which excludes the ray tracing and mesh shader feature set. This is an architectural feature gap, not just a performance gap.

Shader organization differs as well. The G3's 1280 shading units are organized with 40 TMUs and 20 ROPs, while the 48EU Mobile's 384 shading units are organized with 24 TMUs and 8 ROPs. The ratio of TMUs to shading units is notably different: the G3 has one TMU per 32 shading units, while the 48EU Mobile has one TMU per 16 shading units. This suggests different texture pipeline balancing between the two architectures.

The FP16 implementation is consistent across both parts, with each recording a 2:1 ratio. However, the absolute throughput difference is large: 12.29 TFLOPS for the G3 versus 2.765 TFLOPS for the 48EU Mobile. Both architectures support the same OpenGL and Vulkan versions, indicating that API-level compatibility is not a differentiator outside of DirectX.

The power delivery design also differs. The G3 records no power connector and is rated at 25 W, while the 48EU Mobile also records no power connector but draws 28 W. Both are IGP slot width parts, meaning they are integrated into the host device rather than installed as discrete cards. The G3 achieves higher performance at lower power, which is consistent with the combined benefits of the newer architecture and the smaller process node.

The recorded data does not include transistor counts, die sizes, tensor core counts, or cache hierarchies for either part, so those architectural details cannot be compared. The available evidence points to a clean generational split: the G3 is the newer, denser, more capable part by every measured performance metric, while the 48EU Mobile is the earlier, less capable design with a higher power draw.
