Architecture Differences

The two GPUs belong to different architectural generations and design philosophies. The Intel Arc A310E is built on the Xe-HPG architecture, a high-performance graphics architecture designed for discrete gaming and workstation workloads. It uses the DG2-128 chip manufactured on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9 million per mm². The UHD Graphics 770 Mobile, by contrast, uses the Generation 12.2 architecture, which is an integrated graphics solution built into the Raptor Lake processor. It is manufactured on a 10 nm Intel process, though the database records no transistor count, die size, or density figures for it.

The memory architecture marks a fundamental split. The Arc A310E has a dedicated 4 GB GDDR6 frame buffer on a 64-bit bus, providing a fixed 124.0 GB/s of bandwidth. The UHD Graphics 770 Mobile has no dedicated memory; it uses System Shared memory, meaning its bandwidth is System Dependent on the host system's memory configuration. This is a critical distinction for workloads that require consistent, high-bandwidth memory access.

The compute configurations are heavily skewed toward the discrete part. The Arc A310E packs 768 shading units, 32 TMUs, and 16 ROPs, plus 6 ray tracing cores. The UHD Graphics 770 Mobile has 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing support listed. The Arc A310E's boost clock of 2000 MHz is constant across base and boost, while the UHD 770 ramps from 300 MHz to a 1600 MHz boost. The Arc A310E's higher clock speed combined with triple the shading units produces a significant compute advantage: 3.072 TFLOPS FP32 versus 819.2 GFLOPS.

Power and physical design also diverge. The Arc A310E is a discrete single-slot card measuring 168 mm in length, 69 mm in height, and 20 mm in width, with a TDP of 75 W and a suggested PSU of 250 W. It requires no power connectors. The UHD Graphics 770 Mobile is an IGP with a 15 W TDP, no physical dimensions, and no power connector information. The Arc A310E uses a PCIe 4.0 x8 bus interface, while the UHD 770 uses the Ring Bus internal to the processor.

The Arc A310E supports DirectX 12 Ultimate (12_2), which includes advanced features like ray tracing and mesh shaders. The UHD Graphics 770 Mobile supports DirectX 12 (12_1), a slightly lower feature level that omits some of the DirectX 12 Ultimate capabilities. Both support OpenGL 4.6 and Vulkan 1.4.

The production status differs as well: the Arc A310E is marked as end-of-life, with a release date of 2024-03-31, while the UHD Graphics 770 Mobile is active, released on 2023-01-03. The Arc A310E's predecessor is Xe Graphics and its successor is Battlemage. The UHD 770's successor is Arc Graphics-M, and it has no recorded predecessor.

The Verdict

The data indicates a clear performance hierarchy, but the choice depends on the use case. The Intel Arc A310E, with 3.072 TFLOPS FP32, 768 shading units, 6 ray tracing cores, and 124.0 GB/s of dedicated bandwidth, is positioned for discrete graphics workloads that demand sustained throughput. Its DirectX 12 Ultimate support enables hardware ray tracing and the full feature set of modern game engines. The UHD Graphics 770 Mobile, with 819.2 GFLOPS FP32, 256 shading units, and no ray tracing cores, is an integrated solution aimed at basic display output and light 2D or low-demand 3D tasks.

For users who need a dedicated, single-slot graphics card with its own memory and a 75 W power envelope, the Arc A310E is the clear choice. It delivers 3.75 times the FP32 throughput of the UHD 770 (3.072 TFLOPS versus 819.2 GFLOPS) and has 4 GB of dedicated GDDR6, which eliminates memory bandwidth contention. Its 6 ray tracing cores provide hardware acceleration that the UHD 770 lacks entirely.

For systems where power efficiency is paramount, such as thin-and-light laptops or fanless designs, the UHD Graphics 770 Mobile's 15 W TDP (versus 75 W) is a substantial advantage. It is an IGP with no physical footprint, no power connectors, and no dedicated memory requirements. It is actively produced, while the Arc A310E is end-of-life.

The percentile ranking for both is the same at 50, but that percentile is based on an average benchmark score of 0 for both, so it does not provide meaningful differentiation. The recorded data shows no head-to-head benchmarks, no wins for either side, and no nearest rivals. The verdict must therefore rest on the raw specifications.

The Arc A310E is the superior performer in every compute metric. The UHD Graphics 770 Mobile is the superior choice for integrated, low-power, portable scenarios. The Arc A310E is for a fixed installation with a power budget of at least 75 W and a need for discrete memory. The UHD 770 is for a mobile processor where the GPU shares system resources.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results, no wins for either GPU, and no average benchmark scores. The percentile for both is 50, but this is derived from an average score of 0, which provides no comparative data. The nearest rivals lists are empty for both parts.

Without benchmark data, the recorded specifications must serve as the basis for comparison. The Arc A310E's FP32 throughput of 3.072 TFLOPS is exactly 3.75 times the UHD 770's 819.2 GFLOPS. The pixel rate of 32.00 GPixel/s is 2.5 times the UHD's 12.80 GPixel/s. The texture rate of 64.00 GTexel/s is exactly 2.5 times the UHD's 25.60 GTexel/s. The FP16 output of 6.144 TFLOPS is 3.75 times the UHD's 1.638 TFLOPS.

The shading unit count is three times higher (768 versus 256). The TMU count is double (32 versus 16). The ROP count is double (16 versus 8). The Arc has 6 ray tracing cores; the UHD has none. The memory bandwidth of 124.0 GB/s is dedicated, whereas the UHD's bandwidth is System Dependent, which in practice is shared with CPU and other system components.

The clock speed difference is notable: the Arc runs at a constant 2000 MHz, while the UHD boosts to 1600 MHz. The Arc's boost clock is 25% higher than the UHD's boost clock. The Arc's base clock is 2000 MHz versus the UHD's 300 MHz, a 6.67 times difference at the base level.

The DirectX feature level difference (12_2 versus 12_1) means the Arc supports ray tracing and other DirectX 12 Ultimate features, while the UHD does not. This is a qualitative feature gap that the raw compute numbers do not fully capture.

Where Each One Wins

The Arc A310E wins in every compute-heavy scenario. Its 3.072 TFLOPS FP32 and 6.144 TFLOPS FP16 make it suitable for workloads that require sustained floating-point throughput, such as 3D rendering, GPGPU compute, and modern game rendering. The 6 ray tracing cores enable hardware-accelerated ray tracing, which the UHD 770 cannot do at all. The 4 GB of dedicated GDDR6 with 124.0 GB/s bandwidth ensures that memory-intensive textures and geometry do not compete with system memory traffic. The 4x mini-DisplayPort 2.0 outputs allow for multi-monitor setups with high-bandwidth display connections.

The UHD Graphics 770 Mobile wins in power-constrained and integration-focused scenarios. Its 15 W TDP is one-fifth of the Arc's 75 W TDP, making it viable in fanless or passively cooled designs. As an IGP, it has no physical slot requirement, no power connectors, and no dedicated memory allocation. Its System Shared memory model means it scales with the host system's RAM, which can be an advantage in systems where adding a discrete GPU is not possible. Its Ring Bus interface eliminates the need for a PCIe slot. It is an active product, while the Arc is end-of-life.

The DirectX 12 (12_1) support of the UHD 770 is sufficient for basic 3D acceleration and video playback. Its 819.2 GFLOPS and 12.80 GPixel/s are adequate for 2D desktop compositing, video decode, and light gaming at low resolutions. The Arc A310E, with its higher pixel rate and texture rate, is better suited for higher-resolution output and more complex shader workloads.

The production status difference is relevant for long-term system planning. The Arc A310E being end-of-life may affect availability, while the UHD 770 being active means it remains in current processors. The release dates show the Arc launched about 15 months after the UHD.

The choice is not ambiguous. The Arc A310E is for users who need a discrete, dedicated graphics solution with ray tracing, high FP32 throughput, and its own memory. The UHD Graphics 770 Mobile is for users who need a low-power, integrated graphics solution with no physical footprint and minimal power draw. The data shows no middle ground: each GPU is optimized for a fundamentally different deployment scenario.
