Intel Arc A380E x2 vs Intel Iris Xe Graphics 80EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no benchmark scores for either the Intel Arc A380E x2 or the Intel Iris Xe Graphics 80EU Mobile. Both entries show an average benchmark score of zero in the database, and the head-to-head benchmark list is empty. Consequently, there are no measured wins for either side in this comparison.

The absence of benchmark results means the percentile ranking for both products sits at 50 against all GPUs in the database. This identical percentile is a placeholder value rather than a performance indicator, as no empirical data exists to differentiate their standing.

The Arc A380E x2 delivers a peak FP32 throughput of 4.096 TFLOPS, which is more than double the 1.856 TFLOPS recorded for the Iris Xe 80EU. The Arc part also reaches 8.192 TFLOPS in FP16 with a 2:1 ratio, compared to 3.712 TFLOPS for the integrated GPU. These compute figures represent the theoretical ceilings for each architecture, not measured application performance.

Pixel throughput shows a similar gap. The Arc A380E x2 achieves 64.00 GPixel/s, while the Iris Xe 80EU manages 29.00 GPixel/s. Texture fill rates differ by a wider margin: 128.0 GTexel/s versus 58.00 GTexel/s. These raw throughput numbers indicate the discrete solution has substantially more fill capacity, but without benchmark scores, real-world scaling cannot be quantified.

The database records zero wins for each product in the head-to-head comparison. This does not imply parity; it reflects the complete lack of measured data in this entry.

Where Each One Wins

From the available specification data, the Arc A380E x2 holds the advantage in every compute and memory metric. It provides 6 GB of dedicated GDDR6 memory on a 96-bit bus, yielding 186.0 GB/s of bandwidth. The Iris Xe 80EU uses system shared memory with bandwidth described as system dependent, which ties its available throughput directly to the host platform's memory configuration.

The Arc A380E x2 supports DirectX 12 Ultimate (12_2), while the Iris Xe 80EU is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The discrete card also includes 8 ray tracing cores; the integrated part lists none. This gives the Arc A380E x2 a feature set advantage for applications that use hardware-accelerated ray tracing.

The Arc A380E x2 provides 1024 shading units, 64 texture mapping units, and 32 render output units. The Iris Xe 80EU has 640 shading units, 40 TMUs, and 20 ROPs. Every unit count favors the discrete solution by a factor of 1.6 across the board.

Clock behavior also splits the two. The Arc A380E x2 runs at a fixed 2000 MHz for both base and boost. The Iris Xe 80EU idles at 300 MHz and boosts to 1450 MHz, meaning its sustained performance depends on thermal and power headroom inside the host system.

The Arc A380E x2 is a single-slot card at 265 mm in length, 127 mm in height, and 20 mm in width. It requires one 6-pin power connector and a 300 W suggested power supply. The Iris Xe 80EU is an integrated graphics processor with no separate dimensions, power connector, or PSU requirement. It draws 15 W, while the Arc A380E x2 is rated at 130 W.

Architecture Differences

The two GPUs come from different architectural generations. The Arc A380E x2 uses the DG2-128 chip built on Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. It is fabricated by TSMC on a 6 nm process with 7,200 million transistors on a 157 mm² die, producing a transistor density of 45.9M per mm².

The Iris Xe 80EU uses the Raptor Lake chip built on Generation 12.2 architecture, listed under HD Graphics-M (Raptor Lake). It is fabricated by Intel on a 10 nm process. The database records no transistor count, die size, or transistor density for this part.

Memory architecture differs fundamentally. The Arc A380E x2 has dedicated GDDR6 memory clocked at 1937 MHz with 15.5 Gbps effective speed. The Iris Xe 80EU relies entirely on system shared memory with no dedicated VRAM, making its effective bandwidth dependent on the host platform.

The Arc A380E x2 connects through a PCIe 4.0 x8 interface. The Iris Xe 80EU uses a Ring Bus interface, which is typical for integrated graphics tied directly to the processor.

Display output capabilities also diverge. The Arc A380E x2 offers 8x mini-DisplayPort 2.0 outputs. The Iris Xe 80EU has display outputs described as portable device dependent, reflecting its role in laptops and compact systems.

Production status and release timing differ as well. The Arc A380E x2 is end-of-life and was released on 2024-03-31. Its predecessor is Xe Graphics and its successor is Battlemage. The Iris Xe 80EU is active, released on 2023-01-03, with no predecessor listed and Arc Graphics-M as its successor.

The Arc A380E x2 is a discrete, single-slot card requiring external power. The Iris Xe 80EU is an IGP with no slot width, no power connectors, and no suggested PSU rating. The power envelope difference is substantial: 130 W for the discrete card versus 15 W for the integrated solution.

The Verdict

The database contains no benchmark scores for either product, so any selection must rest entirely on the recorded specifications. The Arc A380E x2 exceeds the Iris Xe 80EU in every measured hardware category: shading units (1024 versus 640), TMUs (64 versus 40), ROPs (32 versus 20), FP32 compute (4.096 TFLOPS versus 1.856 TFLOPS), FP16 compute (8.192 TFLOPS versus 3.712 TFLOPS), pixel rate (64.00 GPixel/s versus 29.00 GPixel/s), and texture rate (128.0 GTexel/s versus 58.00 GTexel/s).

The Arc A380E x2 also brings dedicated memory with 186.0 GB/s bandwidth, 8 ray tracing cores, DirectX 12 Ultimate support, and a PCIe 4.0 x8 interface. Its fixed 2000 MHz clock eliminates boost variability. The Iris Xe 80EU counters with a 15 W power draw, no external power requirement, and integration into the host processor.

The Arc A380E x2 suits scenarios where maximum compute throughput and dedicated memory bandwidth matter most. The Iris Xe 80EU fits systems where power consumption and physical footprint are the primary constraints. The data shows no middle ground: the discrete card dominates every listed specification while consuming 115 W more power.

The 50th percentile ranking for both products reflects missing data rather than equivalence. Until benchmark results are recorded, the specification sheet is the only basis for comparison, and it clearly favors the Arc A380E x2 for performance-oriented tasks.
