Architecture Differences

The Intel Arc G3 and Intel UHD Graphics 770 Mobile are built on fundamentally different architectures and process nodes. The Arc G3 uses the Xe3-LPG architecture, fabricated on a 3 nm process node by Intel. The UHD Graphics 770 Mobile uses the Generation 12.2 architecture, fabricated on a 10 nm process node. The process node difference is significant, with the Arc G3 using a much more advanced manufacturing process.

The chips themselves differ as well. The Arc G3 is based on the Panther Lake chip, while the UHD Graphics 770 Mobile is based on the Raptor Lake chip. This reflects the generational gap between the two, with the Arc G3 belonging to the Arc Graphics-M (Panther Lake) generation and the UHD Graphics 770 Mobile belonging to the HD Graphics-M (Raptor Lake) generation.

The execution resources differ dramatically. The Arc G3 has 1280 shading units, 40 texture mapping units, and 20 raster operation units. The UHD Graphics 770 Mobile has 256 shading units, 16 texture mapping units, and 8 raster operation units. The Arc G3 also includes 10 ray tracing cores, a feature entirely absent from the UHD Graphics 770 Mobile.

Both GPUs share the same memory configuration: system shared memory, system shared type, system shared bus width, and system dependent bandwidth. Neither has a dedicated memory bus. The bus interface differs, with the Arc G3 using IGP and the UHD Graphics 770 Mobile using Ring Bus.

The API support shows a clear generational divide. The Arc G3 supports DirectX 12 Ultimate (12_2), while the UHD Graphics 770 Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The power envelope differs as well. The Arc G3 has a TDP of 25 W, while the UHD Graphics 770 Mobile has a TDP of 15 W. Both use no power connectors and are integrated graphics processors with an IGP slot width.

The release dates show the generational gap. The UHD Graphics 770 Mobile was released on 2023-01-03, while the Arc G3 was released on 2026-05-31. The UHD Graphics 770 Mobile lists the Arc Graphics-M as its successor, confirming the Arc G3 is the newer product.

Where Each One Wins

The Intel Arc G3 holds advantages across nearly every measured specification. The data shows the Arc G3 with a 5x shading unit advantage, 2.5x more texture mapping units, and 2.5x more raster operation units. The boost clock is 50% higher at 2400 MHz versus 1600 MHz. The Arc G3 also has the ray tracing cores, which the UHD Graphics 770 Mobile lacks entirely.

The UHD Graphics 770 Mobile has one clear advantage: power consumption. With a TDP of 15 W versus the Arc G3's 25 W, the UHD Graphics 770 Mobile fits into a lower power envelope. This makes it suitable for platforms where power efficiency is prioritized over graphics performance. The UHD Graphics 770 Mobile also uses the Ring Bus interface, which may integrate differently into certain system designs compared to the Arc G3's IGP interface.

The Arc G3 wins on raw compute capability. Its FP32 throughput is 6.144 TFLOPS, which is 7.5x higher than the UHD Graphics 770 Mobile's 819.2 GFLOPS. The FP16 throughput follows the same pattern, with the Arc G3 delivering 12.29 TFLOPS (2:1) versus the UHD Graphics 770 Mobile's 1.638 TFLOPS (2:1). The pixel rate and texture rate also favor the Arc G3, with 48.00 GPixel/s versus 12.80 GPixel/s, and 96.00 GTexel/s versus 25.60 GTexel/s, respectively.

Both GPUs are integrated processors, so neither can be installed as a discrete solution. Both have system shared memory with system dependent bandwidth. The display outputs are portable device dependent for both, meaning they rely on the host device for display connectivity.

Head-to-Head Benchmarks

The recorded data does not include runtime benchmark scores for either GPU. Both have an average benchmark score of 0, and the head-to-head benchmark list is empty. The wins counter shows 0 for both GPUs. The percentile versus all GPUs is 50 for both, placing them at the midpoint of the database distribution.

Without measured benchmark results, the specification data provides the basis for performance comparison. The Arc G3's FP32 throughput of 6.144 TFLOPS is 7.5x the UHD Graphics 770 Mobile's 819.2 GFLOPS. In FP16 workloads, the Arc G3 delivers 12.29 TFLOPS (2:1), which is 7.5x the UHD Graphics 770 Mobile's 1.638 TFLOPS (2:1).

The pixel rate difference favors the Arc G3 by a factor of 3.75, with 48.00 GPixel/s versus 12.80 GPixel/s. The texture rate difference is similar, with the Arc G3 at 96.00 GTexel/s versus 25.60 GTexel/s, a 3.75x advantage.

The shading unit count difference of 1280 versus 256 translates directly to the compute throughput ratios. The ray tracing cores on the Arc G3 provide a capability that the UHD Graphics 770 Mobile cannot match, as the older GPU has no ray tracing hardware at all.

The boost clock advantage of 2400 MHz versus 1600 MHz gives the Arc G3 a 50% higher maximum clock speed. Combined with the larger execution resource pool, this compounds the performance gap.

The DirectX support difference matters for modern workloads. The Arc G3 supports DirectX 12 Ultimate (12_2), which includes features not available in the UHD Graphics 770 Mobile's DirectX 12 (12_1) support.

The TDP difference of 25 W versus 15 W means the Arc G3 draws more power to achieve its higher performance levels. The UHD Graphics 770 Mobile operates at a lower power envelope, which may be preferable in thermally constrained portable devices.

Both GPUs are released and active in production. The UHD Graphics 770 Mobile's successor is listed as Arc Graphics-M, which is the generation the Arc G3 belongs to, confirming the Arc G3 represents the newer product line.

The Arc G3's 3 nm process node versus the UHD Graphics 770 Mobile's 10 nm process node indicates a substantial manufacturing advantage. The newer process allows for higher transistor density, which contributes to the Arc G3's larger execution resource pool within its 25 W power envelope.

In summary, the specification data indicates the Arc G3 outperforms the UHD Graphics 770 Mobile across all compute metrics. The UHD Graphics 770 Mobile retains an advantage only in power consumption, delivering its performance at 15 W rather than 25 W.
