Intel Arc A380E x2 vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark comparisons between the Intel Arc A380E x2 and the Intel UHD Graphics 770 Mobile. Neither GPU has any benchmark entries, average scores, or win counts in the recorded data. The percentile ranking for both parts sits at the same position, the 50th percentile against all GPUs in the database. Without direct measurement data, the analysis must rely entirely on the architectural and specification differences recorded for each part.

The Arc A380E x2 delivers 4.096 TFLOPS of FP32 compute, which is five times the 819.2 GFLOPS recorded for the UHD Graphics 770 Mobile. The texture rate shows a similar gap: 128.0 GTexel/s versus 25.60 GTexel/s, a fivefold difference. Pixel throughput tells the same story, with the Arc part reaching 64.00 GPixel/s compared to 12.80 GPixel/s for the integrated graphics. These are the largest recorded numerical gaps between the two products.

The memory subsystem widens the divide further. The Arc A380E x2 uses 6 GB of GDDR6 on a 96 bit bus, producing 186.0 GB/s of bandwidth. The UHD Graphics 770 Mobile relies on system shared memory with bandwidth listed as system dependent. The dedicated memory interface gives the discrete card a fixed, substantial bandwidth advantage that the integrated part cannot match.

Clock behavior also differs sharply. The Arc A380E x2 runs at a constant 2000 MHz for both base and boost. The UHD Graphics 770 Mobile has a 300 MHz base clock and a 1600 MHz boost clock. The integrated part depends on thermal and power headroom to reach its maximum frequency, while the discrete card maintains a steady clock rate.

Architecture Differences

The Arc A380E x2 uses the DG2-128 chip built on the Xe-HPG architecture, part of the Alchemist Arc 3 generation. It is fabricated on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die. The transistor density works out to 45.9M per mm². The UHD Graphics 770 Mobile uses a Raptor Lake chip on the Generation 12.2 architecture, part of the HD Graphics-M product line. It is fabricated on a 10 nm process at Intel. The database records no transistor count or die size for the integrated part.

The execution resources differ by a factor of four. The Arc A380E x2 contains 1024 shading units, 64 texture mapping units, 32 ROPs, and 8 ray tracing cores. The UHD Graphics 770 Mobile contains 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing cores recorded. The discrete card also supports DirectX 12 Ultimate with feature level 12_2, while the integrated part supports DirectX 12 with feature level 12_1. Both parts support OpenGL 4.6 and Vulkan 1.4.

The memory architecture is fundamentally different. The Arc A380E x2 has dedicated 6 GB GDDR6 memory clocked at 1937 MHz, 15.5 Gbps effective, on a 96 bit bus. The UHD Graphics 770 Mobile uses system shared memory with a system shared bus width and system dependent bandwidth. This affects not only capacity but also latency characteristics and the ability to sustain heavy memory workloads.

Power delivery separates the two products as well. The Arc A380E x2 has a 130 W TDP, requires a 300 W suggested power supply, uses a single 6-pin power connector, and occupies a single slot. The UHD Graphics 770 Mobile has a 15 W TDP and is an integrated graphics processor with no power connectors and no separate slot width.

Where Each One Wins

The Arc A380E x2 wins in every recorded compute metric. Its FP32 throughput of 4.096 TFLOPS exceeds the UHD Graphics 770 Mobile's 819.2 GFLOPS by a factor of five. FP16 performance follows the same ratio, with 8.192 TFLOPS versus 1.638 TFLOPS, both operating at a 2:1 ratio relative to FP32.

The discrete card also wins on memory capacity and bandwidth. It has 6 GB of dedicated GDDR6 with 186.0 GB/s of bandwidth. The integrated part has no dedicated memory allocation and its bandwidth is system dependent, meaning it varies with the host platform's memory configuration. For workloads that are sensitive to memory bandwidth, the Arc A380E x2 provides a fixed and far larger resource.

The UHD Graphics 770 Mobile wins on power efficiency in absolute terms. Its 15 W TDP is dramatically lower than the 130 W TDP of the Arc A380E x2. It also wins on physical integration, since it is an IGP with no separate card dimensions, no power connectors, and no power supply requirement. The integrated part fits into any system built around a Raptor Lake processor without additional hardware.

The Arc A380E x2 wins on display output capability. It provides 8x mini-DisplayPort 2.0 outputs, while the UHD Graphics 770 Mobile's display outputs are listed as portable device dependent. The discrete card offers a fixed, high-bandwidth multi-display configuration. The integrated part's output capability depends entirely on the host device's design.

The Arc A380E x2 also wins on production status considerations. It is recorded as end-of-life with a successor in Battlemage. The UHD Graphics 770 Mobile is active with a successor in Arc Graphics-M. The discrete part has a predecessor in Xe Graphics, while no predecessor is recorded for the integrated part.

Specification Differences

The Verdict

The recorded data separates these two GPUs into distinct roles. The Arc A380E x2 is a discrete, single-slot card with dedicated GDDR6 memory, 1024 shading units, 8 ray tracing cores, and a constant 2000 MHz clock. It delivers 4.096 TFLOPS of FP32 compute, 186.0 GB/s of memory bandwidth, and supports DirectX 12 Ultimate. Its 130 W TDP and 300 W suggested power supply indicate a system designed for sustained graphics workloads.

The UHD Graphics 770 Mobile is an integrated processor with 256 shading units, no ray tracing cores, and a 15 W TDP. Its performance metrics are uniformly lower across pixel rate, texture rate, and compute throughput. Its memory bandwidth is system dependent, meaning performance scales with the host platform's memory configuration. It supports DirectX 12 at feature level 12_1.

The choice between these parts depends entirely on the system context. The Arc A380E x2 suits systems that need fixed, high-bandwidth graphics performance with dedicated memory and multi-display output via 8x mini-DisplayPort 2.0. The UHD Graphics 770 Mobile suits portable or low-power systems where the 15 W TDP and integrated form factor are priorities, and where graphics performance is secondary to power efficiency.

The data shows no benchmark scores for either part, so performance conclusions rest on the recorded architectural specifications. The compute, texture, and pixel rate ratios are all exactly 5:1 in favor of the Arc A380E x2. The memory bandwidth is fixed at 186.0 GB/s for the discrete card versus system dependent for the integrated part. These are the decisive recorded differences.
