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

Head-to-Head Benchmarks

The recorded database does not contain direct head-to-head benchmark entries for the Intel Arc A380E versus the Intel Iris Xe Graphics 80EU Mobile. Both parts register an identical percentile position of 50 against all GPUs, and both show an average benchmark score of 0 in the current dataset. This means the two cannot be separated by aggregate performance metrics at this time.

What the data does allow is a comparison of their theoretical throughput ceilings, which are firmly in favor of the Arc A380E. The Arc A380E delivers 4.096 TFLOPS of FP32 compute, while the Iris Xe Graphics 80EU Mobile delivers 1.856 TFLOPS. That places the discrete part at approximately 2.2 times the floating-point throughput of the integrated solution. FP16 rates follow the same pattern: 8.192 TFLOPS for the Arc A380E versus 3.712 TFLOPS for the Iris Xe part, both with a 2:1 ratio to FP32.

Pixel throughput tells a similar story. The Arc A380E reaches 64.00 GPixel/s, while the Iris Xe Graphics 80EU Mobile reaches 29.00 GPixel/s. Texture rate is 128.0 GTexel/s on the Arc A380E against 58.00 GTexel/s on the Iris Xe. In each case the Arc A380E holds a lead of just over two to one. These figures represent theoretical limits based on clock speed and execution resource counts, not application-level results, but they indicate a substantial performance class gap between the two products.

Clock behavior also differs sharply. The Arc A380E runs at a fixed 2000 MHz for both base and boost, suggesting a steady-state design that does not rely on power-limited boosting. The Iris Xe Graphics 80EU Mobile idles at a 300 MHz base clock and boosts to 1450 MHz, which is typical of an integrated part sharing power and thermal budgets with a CPU. The Arc A380E therefore sustains a higher frequency across the board, and it does so with dedicated memory rather than borrowing system RAM.

Memory bandwidth is another major separator. The Arc A380E uses 6 GB of GDDR6 on a 96-bit bus, producing 186.0 GB/s of bandwidth. The Iris Xe Graphics 80EU Mobile uses System Shared memory with bandwidth listed as System Dependent. No fixed bandwidth number exists for the integrated part, but the dependency on shared system memory means the available bandwidth is not guaranteed and will vary with platform configuration. The discrete card's 186.0 GB/s is a fixed, dedicated resource.

The Arc A380E also wins on API feature level. It supports DirectX 12 Ultimate (12_2), while the Iris Xe Graphics 80EU Mobile supports DirectX 12 (12_1). Both parts support OpenGL 4.6 and Vulkan 1.4. The DirectX 12 Ultimate designation on the Arc A380E indicates support for the full feature set associated with that tier, including hardware ray tracing, which is present in the form of 8 ray tracing cores. The Iris Xe part lists no ray tracing cores at all.

Architecture Differences

The two GPUs come from different manufacturing and design lineages. The Intel Arc A380E is built on the DG2-128 chip using the Xe-HPG architecture, which belongs to the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC. The Intel Iris Xe Graphics 80EU Mobile is built on the Raptor Lake chip using Generation 12.2 architecture, part of the HD Graphics-M (Raptor Lake) family. It is fabricated on a 10 nm process at Intel. The process node gap, 6 nm versus 10 nm, is significant for transistor density and power efficiency.

Transistor counts are only recorded for the Arc A380E: 7,200 million transistors on a 157 mm² die, yielding a density of 45.9 million transistors per square millimeter. No transistor count, die size, or density figure exists in the database for the Iris Xe Graphics 80EU Mobile, so a direct comparison of die economics is not possible.

Execution resource counts differ at every level. The Arc A380E has 1024 shading units, 64 texture mapping units, and 32 ROPs. The Iris Xe Graphics 80EU Mobile has 640 shading units, 40 TMUs, and 20 ROPs. The execution resource ratio is roughly 1.6 to 1 in favor of the discrete part, which is smaller than the FP32 throughput ratio because the Arc A380E also runs at a higher clock. The Arc A380E includes 8 ray tracing cores; the Iris Xe part has none listed.

Memory architecture is completely different. The Arc A380E uses dedicated 6 GB GDDR6 memory at 1937 MHz (15.5 Gbps effective) on a 96-bit bus. The Iris Xe Graphics 80EU Mobile uses System Shared memory with a System Shared bus width and System Dependent bandwidth. The discrete part's memory clock is fixed and independent of host system memory speed. The integrated part's performance is tied to the host platform's memory subsystem.

Power and physical design also diverge. The Arc A380E has a TDP of 75 W, is a single-slot card, draws power through the PCIe slot with no additional power connectors, and requires a 250 W suggested power supply. It is 254 mm long, 127 mm high, and 20 mm wide. The Iris Xe Graphics 80EU Mobile is an IGP with a 15 W TDP, has no slot width, no power connector listing, and no dimensions. The integrated part uses a Ring Bus interface, while the discrete card uses PCIe 4.0 x8.

Production status differs as well. The Arc A380E is listed as End-of-life, with a release date of 2024-03-31. The Iris Xe Graphics 80EU Mobile is listed as Active, with a release date of 2023-01-03. The Iris Xe part's successor is listed as Arc Graphics-M, while the Arc A380E's predecessor is Xe Graphics and its successor is Battlemage.

Where Each One Wins

The Arc A380E wins on every recorded performance metric. It has higher FP32 and FP16 throughput, higher pixel rate, higher texture rate, more shading units, more TMUs, more ROPs, dedicated memory with fixed bandwidth, and hardware ray tracing support. It also sustains a higher clock speed and supports DirectX 12 Ultimate. For any workload that scales with raw compute throughput, texture filtering, or pixel fill, the data points squarely at the discrete card.

The Iris Xe Graphics 80EU Mobile wins on power draw and integration. Its 15 W TDP is one-fifth of the Arc A380E's 75 W TDP. It requires no separate card, no power supply recommendation, and no physical slot beyond the motherboard. It is an integrated part designed for portable devices, with display outputs listed as Portable Device Dependent. The Arc A380E, by contrast, is a 254 mm add-in board with four DisplayPort 2.0 outputs and a 250 W suggested power supply. The Iris Xe part is also listed as Active production, whereas the Arc A380E is End-of-life.

The Iris Xe part also has a lower base clock, which is not a benefit in performance terms but reflects its role as a power-conserving integrated GPU. Its 300 MHz base clock and 1450 MHz boost clock allow it to idle at very low frequency and draw minimal power. The Arc A380E runs at a constant 2000 MHz, which is better for sustained throughput but worse for idle efficiency.

In use-case terms, the Arc A380E fits scenarios where a fixed, dedicated GPU with known bandwidth and a full DirectX 12 Ultimate feature set is required, and where 75 W of power and single-slot space are acceptable. The Iris Xe Graphics 80EU Mobile fits scenarios where the GPU must share the thermal and power envelope of a mobile CPU, where memory is shared with the system, and where no discrete card can be installed.

The ray tracing difference is a decisive feature split. The Arc A380E has 8 ray tracing cores. The Iris Xe Graphics 80EU Mobile has none listed. Any workload that requires hardware-accelerated ray tracing can only run on the Arc A380E. This also aligns with the DirectX 12 Ultimate versus DirectX 12 (12_1) API split, since ray tracing is part of the higher feature tier.
