Intel Arc A380E x2 vs Intel Arc Graphics 64EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data for this comparison contains no direct head-to-head benchmark results. Both the Intel Arc A380E x2 and the Intel Arc Graphics 64EU Mobile return an average benchmark score of 0 and hold identical percentile placements at the 50th percentile among all GPUs in the database. The win counts are also tied at zero each, meaning the database has no measured performance deltas between these two parts.

What can be established from the raw specifications is the theoretical compute ceiling for each. The Arc A380E x2 delivers 4.096 TFLOPS of FP32 throughput. The Arc Graphics 64EU Mobile delivers 1.792 TFLOPS. That places the discrete card at roughly 2.3 times the raw shader throughput of the integrated part. On the FP16 side, the A380E x2 reaches 8.192 TFLOPS with a 2:1 ratio, while the mobile part reaches 3.584 TFLOPS under the same ratio. These are not measured benchmark scores, but they define the upper bound of what each architecture can express in compute-bound workloads.

Pixel and texture rates tell a similar story. The A380E x2 produces 64.00 GPixel/s and 128.0 GTexel/s. The mobile part produces 28.00 GPixel/s and 56.00 GTexel/s. Again, the discrete card holds a clear advantage, roughly 2.3 times in both metrics. The lack of actual benchmark deltas means no single workload can be declared a win for either side from measured data. The specification comparison, however, consistently favors the discrete card by a wide margin across every throughput metric.

Architecture Differences

The two GPUs come from different Intel families. The Arc A380E x2 uses the DG2-128 chip built on the Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. The Arc Graphics 64EU Mobile uses the Meteor Lake chip built on the Xe-LPG architecture, placed in the Arc Graphics-M (Meteor Lake) generation. The process nodes differ substantially: the A380E x2 is fabricated by TSMC on a 6 nm process, while the mobile part is fabricated by Intel on a 10 nm process.

The transistor counts are not comparable because the mobile part has no listed transistor count or die size in the database. The A380E x2 carries 7,200 million transistors on a 157 mm² die, resulting in a transistor density of 45.9M per mm². The mobile part lists no die dimensions at all.

Execution resources scale with the chip class. The A380E x2 has 1024 shading units, 64 texture mapping units, 32 ROPs, and 8 ray tracing cores. The Arc Graphics 64EU Mobile has 512 shading units, 32 TMUs, and 16 ROPs. It lists no ray tracing cores in the database. The EU count implied by the name, 64 execution units, aligns with the halved shading unit count compared to the discrete card.

Memory architecture is fundamentally different. The A380E x2 uses 6 GB of dedicated GDDR6 memory on a 96 bit bus, with 186.0 GB/s of bandwidth and memory clocks at 1937 MHz, or 15.5 Gbps effective. The mobile part uses System Shared memory, meaning its size, type, bus width, and bandwidth are all dependent on the host system. The database records the bandwidth as System Dependent. Clock behavior also diverges. The A380E x2 runs at a flat 2000 MHz for both base and boost. The mobile part runs at a 300 MHz base clock and boosts to 1750 MHz.

API support differs in the DirectX version. The A380E x2 supports DirectX 12 Ultimate (12_2), while the mobile part supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The discrete card uses a PCIe 4.0 x8 bus interface, while the mobile part connects through a Ring Bus.

Power and physical design are also distinct. The A380E x2 has a 130 W TDP, is single-slot, requires a 1x 6-pin power connector, and suggests a 300 W power supply. It measures 265 mm by 127 mm by 20 mm. The mobile part has a 65 W TDP, is an IGP, has no power connector, no suggested PSU, and no listed dimensions. Display outputs for the discrete card are 8x mini-DisplayPort 2.0, while the mobile part's outputs are listed as Portable Device Dependent.

Where Each One Wins

The A380E x2 wins on raw compute resources. Its 1024 shading units outnumber the mobile part's 512. Its 64 TMUs double the mobile part's 32. Its 32 ROPs double the mobile part's 16. Its 8 ray tracing cores exist where the mobile part lists none. In any workload that scales with shader count, texture fill, or pixel fill, the discrete card has a structural advantage.

The mobile part wins on integration. It is an IGP with a 65 W TDP, no power connector, and no separate card dimensions. It can operate inside a laptop where a 130 W single-slot card with a 265 mm length cannot physically fit. The 300 MHz base clock and 1750 MHz boost clock suggest power management is a priority, as does the System Shared memory model that avoids dedicated VRAM costs. The mobile part's DirectX 12 (12_1) support covers most current game titles, though it lacks the 12_2 feature set of the discrete card.

The A380E x2 also wins on memory bandwidth. Dedicated GDDR6 at 186.0 GB/s is a fixed resource, whereas the mobile part's bandwidth is System Dependent and shared with the CPU. In memory-heavy scenarios, the discrete card's dedicated 6 GB pool provides predictable performance. The mobile part's shared memory can be larger or smaller depending on the host laptop, which makes its behavior variable.

Production status favors the mobile part. The A380E x2 is listed as End-of-life, while the Arc Graphics 64EU Mobile is Active. The discrete card's predecessor is Xe Graphics and its successor is Battlemage. The mobile part's predecessor is HD Graphics-M and it has no successor listed. Release dates put the A380E x2 at March 31, 2024 and the mobile part at December 13, 2023.

The Verdict

The data indicates two different use cases. The Intel Arc A380E x2 is a discrete, single-slot card with 4.096 TFLOPS FP32, 6 GB of dedicated GDDR6, and a 130 W TDP. It is built for systems that can accommodate a 265 mm card and supply a 6-pin power connector. Its compute throughput is 2.3 times the mobile part in FP32, FP16, pixel rate, and texture rate. For any workload that can use a full PCIe 4.0 x8 connection and dedicated VRAM, the A380E x2 is the stronger part.

The Intel Arc Graphics 64EU Mobile is an integrated GPU inside a Meteor Lake chip. It has 1.792 TFLOPS FP32, 512 shading units, and a 65 W TDP. It uses system memory and depends on the host platform for bandwidth. It fits in laptops and other portable devices where no expansion slot exists. Its DirectX 12 (12_1) support is one feature level behind the discrete card's 12 Ultimate (12_2).

The database shows no measured benchmark scores for either part. The verdict must rest on specifications. Users who need maximum throughput in a desktop or rack system should pick the A380E x2. Users who need graphics in a mobile platform with no discrete card slot should pick the Arc Graphics 64EU Mobile. The production status matters for long-term availability: the A380E x2 is end-of-life, so supply may shrink over time, while the mobile part remains active in the database.
