Intel Arc G3 Extreme vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for these two integrated graphics solutions. Both the Intel Arc G3 Extreme and the Intel UHD Graphics 770 Mobile return empty benchmark arrays, zero win counts on each side, and identical average benchmark scores of zero. The percentile ranking for both parts sits at the 50th mark against all GPUs in the database, which reflects the absence of comparable test data rather than any meaningful performance equivalence.

What the data does permit is a direct comparison of their theoretical compute ceilings, which are listed in the specification records. The Arc G3 Extreme delivers 7.680 TFLOPS of FP32 throughput, while the UHD Graphics 770 Mobile produces 819.2 GFLOPS. That places the Arc part at 9.4 times the raw shader throughput of the older Raptor Lake graphics. In FP16, the Arc G3 Extreme reaches 15.36 TFLOPS with a 2:1 ratio, compared to 1.638 TFLOPS for the UHD 770 Mobile, a multiple of roughly 9.4 again. The gap is consistent across both precision formats, indicating a generational scaling in execution resources rather than an architectural quirk.

Pixel and texture throughput tell the same story. The Arc G3 Extreme records 60.00 GPixel/s and 120.0 GTexel/s. The UHD Graphics 770 Mobile manages 12.80 GPixel/s and 25.60 GTexel/s. The Arc part leads by 4.7 times in pixel fill and by the same factor in texture fill. These figures come from the clock and unit counts in the database, not from any measured application performance, so they represent the theoretical maximums that the hardware can sustain.

Because the head-to-head benchmark field is empty, the database cannot provide real-world frame rates, workload-specific wins, or thermal behavior under load. The analysis below therefore relies entirely on the architectural and specification differences recorded for each part, plus the compute and fill rate figures that are present in the data.

Architecture Differences

The two GPUs come from different Intel design generations and use distinct architectures. The Arc G3 Extreme is built on the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. The UHD Graphics 770 Mobile uses Generation 12.2 architecture from the HD Graphics-M (Raptor Lake) generation. The chip for the Arc part is Panther Lake, while the UHD part uses Raptor Lake.

The process node separates them sharply. The Arc G3 Extreme is fabricated on Intel's 3 nm node. The UHD Graphics 770 Mobile is on a 10 nm node. That difference in process geometry contributes to the large gap in transistor density and power efficiency, though the database does not list transistor counts or die sizes for either part.

The execution pipeline differs in scale and capability. The Arc G3 Extreme has 1536 shading units, 48 TMUs, 24 ROPs, and 12 dedicated ray tracing cores. The UHD Graphics 770 Mobile has 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing hardware at all. This means the Arc part can handle hardware-accelerated ray tracing workloads, while the UHD part must rely on software fallbacks if any ray tracing is attempted.

The DirectX feature level also differs. The Arc G3 Extreme supports DirectX 12 Ultimate with feature level 12_2, which includes features like variable rate shading and mesh shaders. The UHD Graphics 770 Mobile supports DirectX 12 at feature level 12_1, which lacks some of the newer pipeline features. Both support OpenGL 4.6 and Vulkan 1.4, so API compatibility is otherwise identical.

The bus interface differs as well. The Arc G3 Extreme uses an IGP interface, while the UHD Graphics 770 Mobile connects via a Ring Bus. Both are integrated parts with no separate slot width, and both use system shared memory. The display outputs are listed as portable device dependent for both, meaning the available connectors depend on the laptop or handheld design.

Specification Differences

The database records several fields where the two GPUs differ. Clock speeds: the Arc G3 Extreme has a 2500 MHz boost, the UHD Graphics 770 Mobile has a 1600 MHz boost, and both share a 300 MHz base. Shading units: 1536 versus 256. TMUs: 48 versus 16. ROPs: 24 versus 8. Ray tracing cores: 12 versus none.

Pixel rate: 60.00 GPixel/s for the Arc part, 12.80 GPixel/s for the UHD part. Texture rate: 120.0 GTexel/s versus 25.60 GTexel/s. FP32 throughput: 7.680 TFLOPS versus 819.2 GFLOPS. FP16 throughput: 15.36 TFLOPS versus 1.638 TFLOPS, both with a 2:1 ratio. TDP: 80 W versus 15 W. Process node: 3 nm versus 10 nm. DirectX version: 12 Ultimate (12_2) versus 12 (12_1).

The architecture, chip, generation, and bus interface fields all differ as listed in the previous section. The release dates are not identical: the Arc G3 Extreme is recorded with a release date of May 31, 2026, while the UHD Graphics 770 Mobile has a release date of January 3, 2023. The production status for both is Active. The UHD Graphics 770 Mobile lists a successor as Arc Graphics-M, which aligns with the Arc G3 Extreme's generation.

Fields that are the same between the two parts include the manufacturer (Intel), the foundry (Intel), memory size/type/bus width (all system shared), memory bandwidth (system dependent), slot width (IGP), display outputs (portable device dependent), OpenGL (4.6), Vulkan (1.4), and the absence of a launch MSRP in the database.

Where Each One Wins

The Arc G3 Extreme wins on raw compute throughput by a wide margin. Its FP32 figure of 7.680 TFLOPS is roughly 9.4 times the UHD Graphics 770 Mobile's 819.2 GFLOPS. That advantage applies to any workload that scales with shader execution, including general-purpose compute, modern game rendering, and GPU-accelerated applications. The texture rate of 120.0 GTexel/s versus 25.60 GTexel/s means the Arc part can feed its shading units with filtered textures much faster, which matters for detailed scene rendering.

The Arc G3 Extreme also wins on feature support. It has 12 ray tracing cores, which the UHD Graphics 770 Mobile lacks entirely. DirectX 12 Ultimate support at feature level 12_2 enables hardware features that the older 12_1 part cannot use. The higher boost clock of 2500 MHz versus 1600 MHz gives the Arc part a per-cycle advantage on top of its larger execution resource pool.

The UHD Graphics 770 Mobile wins on power draw. Its 15 W TDP is far below the Arc G3 Extreme's 80 W. For a thin-and-light laptop or a fanless design where battery life and thermal headroom are the primary constraints, the UHD part consumes a fraction of the power budget. The lower clock and fewer units produce less heat, which can be an advantage in passively cooled systems or devices with minimal chassis ventilation. The UHD part also has an earlier release date, so it is available in platforms that shipped before the Arc part's 2026 launch window.

The Verdict

The data points in one direction for performance. The Intel Arc G3 Extreme delivers roughly 9.4 times the FP32 throughput of the Intel UHD Graphics 770 Mobile, along with 4.7 times the pixel fill rate and 4.7 times the texture fill rate. It adds ray tracing hardware, supports DirectX 12 Ultimate, and boosts to 2500 MHz. Any workload that depends on shader throughput, fill rate, or modern graphics features will be dramatically faster on the Arc part.

The UHD Graphics 770 Mobile is the choice only when power consumption is the dominant factor. Its 15 W TDP is one-sixth of the Arc part's 80 W figure. For basic desktop composition, video playback, and light 2D workloads, the UHD part can handle those tasks with far less energy draw. It also fits into platforms built around Raptor Lake processors, which may be more common in existing laptop designs.

The choice between the two is therefore a split between capability and efficiency. The Arc G3 Extreme is the part for any graphics-intensive work, including gaming, 3D rendering, or GPU compute, provided the host system can supply 80 W. The UHD Graphics 770 Mobile is the part for minimal-power integrated graphics where battery life and thermal limits matter more than frame rates. The database does not include measured application benchmarks for either part, so real-world performance differences may vary from the theoretical figures recorded here, but the specification gap is substantial enough that the Arc G3 Extreme is the clear performance winner on paper.
