Intel Arc Graphics 4 Xe Mobile vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The database does not contain any recorded head-to-head benchmark runs between the Intel Arc Graphics 4 Xe Mobile and the Intel UHD Graphics 770 Mobile. Both entries have empty benchmark arrays and an average benchmark score of zero. This means direct performance comparisons must be derived from the theoretical throughput figures in the specification records.

The most significant gap appears in raw compute throughput. The Arc Graphics 4 Xe Mobile delivers 2.355 TFLOPS of FP32 performance, while the UHD Graphics 770 Mobile delivers 819.2 GFLOPS. That places the Arc part at roughly 2.9 times the single-precision compute rate of the older integrated graphics. The FP16 figures follow the same pattern: the Arc part reaches 4.710 TFLOPS (2:1) versus 1.638 TFLOPS (2:1) for the UHD 770 Mobile.

Pixel throughput favors the Arc Graphics 4 Xe Mobile as well. The recorded pixel rate is 36.80 GPixel/s against 12.80 GPixel/s for the UHD 770 Mobile. Texture rate shows a similar ratio, with 73.60 GTexel/s versus 25.60 GTexel/s. These numbers indicate that the Arc part can fill and shade a screen faster, which matters for resolution scaling and effects-heavy scenes.

Clock behavior also differs. The Arc Graphics 4 Xe Mobile has a base clock of 300 MHz and a boost clock of 2300 MHz. The UHD Graphics 770 Mobile also starts at 300 MHz but boosts to only 1600 MHz. The higher boost ceiling contributes directly to the compute and fill rate advantages.

Neither part has any recorded benchmark wins in the database, as both win counters sit at zero. The percentile versus all GPUs is identical at 50 for both, which is a placeholder value given the absence of measured scores. The practical interpretation is that the Arc part has a clear theoretical advantage in every measured throughput category, but the database cannot confirm real-world deltas without actual benchmark submissions.

Where Each One Wins

The Intel Arc Graphics 4 Xe Mobile wins in every measured throughput category. FP32 compute is 2.355 TFLOPS versus 819.2 GFLOPS. Pixel rate is 36.80 GPixel/s versus 12.80 GPixel/s. Texture rate is 73.60 GTexel/s versus 25.60 GTexel/s. FP16 compute is 4.710 TFLOPS versus 1.638 TFLOPS. It also brings hardware ray tracing cores, which the UHD 770 Mobile lacks entirely. The higher boost clock of 2300 MHz versus 1600 MHz reinforces the performance gap.

The Intel UHD Graphics 770 Mobile wins on power draw and release timing. Its TDP is 15 W versus 25 W for the Arc part. That 10 W difference matters for thin-and-light laptops where thermal headroom is limited. The UHD 770 Mobile also has a longer driver maturity window, having been released on 2023-01-03 while the Arc Graphics 4 Xe Mobile arrived later on 2026-01-26. For basic desktop composition, video playback, and light productivity, the lower power envelope is an advantage.

The UHD 770 Mobile also holds a manufacturing process advantage in terms of established production. It uses a 10 nm Intel process, while the Arc part uses a 3 nm Intel process. The smaller node does not automatically translate to better efficiency in the recorded data, since the Arc part draws more power despite the newer node. The database shows the Arc part uses 25 W at its specifications, while the UHD 770 Mobile uses 15 W.

Specification Differences

The two GPUs differ across nearly every specification field. Shading units: 512 versus 256. Texture mapping units: 32 versus 16. Raster output units: 16 versus 8. Ray tracing cores: 4 versus none. FP32 throughput: 2.355 TFLOPS versus 819.2 GFLOPS. FP16 throughput: 4.710 TFLOPS versus 1.638 TFLOPS. Pixel rate: 36.80 GPixel/s versus 12.80 GPixel/s. Texture rate: 73.60 GTexel/s versus 25.60 GTexel/s.

Clock speeds differ only at the top end. Base clock is 300 MHz for both. Boost clock is 2300 MHz for the Arc part and 1600 MHz for the UHD part.

Power consumption differs: 25 W for the Arc Graphics 4 Xe Mobile and 15 W for the UHD Graphics 770 Mobile. Both are listed as IGP slot width with portable device dependent display outputs. Neither has a power connector requirement. Neither has a suggested PSU rating.

Memory configuration is identical in structure: system shared size, type, and bus width. Memory bandwidth is system dependent for both.

API support differs in DirectX level. The Arc part supports DirectX 12 Ultimate (12_2). The UHD part supports DirectX 12 (12_1). OpenGL is 4.6 for both, and Vulkan is 1.4 for both.

Release dates differ by roughly three years. The UHD 770 Mobile launched on 2023-01-03. The Arc Graphics 4 Xe Mobile launched on 2026-01-26. The UHD part lists its successor as "Arc Graphics-M", which aligns with the newer part's generation.

Bus interface differs. The Arc part uses IGP. The UHD part uses Ring Bus.

Architecture Differences

The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on a 3 nm Intel process. It belongs to the Arc Graphics-M (Panther Lake) generation. The chip is Panther Lake. The UHD Graphics 770 Mobile uses Generation 12.2 architecture on a 10 nm Intel process. It belongs to the HD Graphics-M (Raptor Lake) generation, with the chip being Raptor Lake.

The core configuration difference is substantial. The Arc part has 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. The UHD part has 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing cores. This is a doubling of every fixed-function unit count plus the addition of dedicated ray tracing hardware.

The memory architecture is the same in concept: both use system shared memory with no dedicated VRAM. Memory bandwidth is system dependent for both. The database records no dedicated memory clock or bus width for either part.

The Xe3-LPG architecture includes support for DirectX 12 Ultimate, which brings features such as mesh shaders and variable rate shading at the 12_2 feature level. The Generation 12.2 architecture in the UHD part is capped at DirectX 12_1, which lacks those newer feature level requirements. Both support OpenGL 4.6 and Vulkan 1.4.

The process node difference is significant: 3 nm for the Arc part versus 10 nm for the UHD part. The newer node allows for more transistors in a given area, though the database does not list transistor counts or die sizes for either GPU. The Arc part uses the newer Panther Lake chip, while the UHD part uses the older Raptor Lake chip.

The Arc Graphics 4 Xe Mobile has a higher TDP of 25 W, which reflects the larger core configuration and higher boost clock. The UHD Graphics 770 Mobile runs at 15 W, which suits lower-power platforms. The production status for both is listed as Active.

The Verdict

The data points to a clear performance hierarchy. The Intel Arc Graphics 4 Xe Mobile delivers over twice the shading units, double the texture units, double the raster output units, and adds ray tracing cores. Its FP32 throughput of 2.355 TFLOPS dwarfs the 819.2 GFLOPS of the UHD Graphics 770 Mobile. The pixel rate of 36.80 GPixel/s versus 12.80 GPixel/s and texture rate of 73.60 GTexel/s versus 25.60 GTexel/s confirm that the Arc part is built for substantially heavier graphics workloads.

The UHD Graphics 770 Mobile retains a role in power-constrained designs. At 15 W, it draws 10 W less than the Arc part. For laptops where battery life and thermals take priority over graphics capability, the UHD part remains a viable option. Its older release date also means it appears in platforms that do not require the newer Panther Lake chip.

Buyers should pick the Arc Graphics 4 Xe Mobile if the workload involves 3D rendering, modern game titles, or any use case that benefits from ray tracing and DirectX 12 Ultimate features. The recorded throughput figures show it is the stronger part in every measured category.

Buyers should pick the UHD Graphics 770 Mobile if the system is built around a 15 W thermal envelope and the graphics workload is limited to desktop, video, and light 2D tasks. The lower power draw is the only recorded advantage, but it is a meaningful one for certain mobile form factors.

The database does not include any measured benchmark scores or rival comparisons for either GPU. The verdict here rests entirely on the specification records. Within those records, the Arc Graphics 4 Xe Mobile is the superior graphics processor by a wide margin.
