Intel Arc A380E x2 vs Intel Arc Graphics 1 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the Intel Arc A380E x2 and the Intel Arc Graphics 1 Xe Mobile. The head-to-head benchmark table is empty, and neither part carries an average benchmark score. Both entries list an average benchmark score of 0, and both sit at the 50th percentile among all GPUs in the database. This lack of measured results means a comparison must be built from the architectural and specification data recorded for each part.

What the data does show is a dramatic difference in raw compute metrics. The Intel Arc A380E x2 delivers 4.096 TFLOPS of FP32 throughput, while the Intel Arc Graphics 1 Xe Mobile delivers 588.8 GFLOPS. In absolute terms, the A380E x2 computes roughly 6.96 times as much FP32 data per second as the mobile part. The gap narrows slightly in FP16, where the A380E x2 reaches 8.192 TFLOPS (2:1) versus 1,177.6 GFLOPS (2:1) for the mobile chip, a ratio of about 6.96 again. These are the largest wins for the A380E x2 in the recorded data.

The pixel and texture rate figures reinforce the same conclusion. The A380E x2 outputs 64.00 GPixel/s and 128.0 GTexel/s. The mobile part outputs 9.200 GPixel/s and 18.40 GTexel/s. The A380E x2 is therefore about 6.96 times faster in pixel throughput and about 6.96 times faster in texture throughput. The consistency across FP32, FP16, pixel, and texture rates indicates a straightforward scaling relationship tied to the number of execution units, rather than any clock or efficiency advantage.

Memory bandwidth shows the widest proportional gap in the entire comparison. The A380E x2 has 186.0 GB/s of dedicated GDDR6 bandwidth over a 96-bit bus. The mobile part uses system shared memory with bandwidth listed as "System Dependent", meaning no fixed figure exists in the database. In configurations where shared memory bandwidth is lower than dedicated GDDR6, the A380E x2 will pull further ahead in bandwidth-sensitive workloads. The mobile part also has no fixed memory size, while the A380E x2 carries 6 GB.

Clock speeds tell a more nuanced story. The A380E x2 runs at a fixed 2000 MHz for both base and boost, with no game clock recorded. The mobile part starts at a very low 300 MHz base but boosts to 2300 MHz, which is 300 MHz higher than the A380E x2's boost. This suggests the mobile chip is designed to idle aggressively and ramp up when needed, while the A380E x2 is a constant-speed discrete card. The mobile part's higher boost clock does not compensate for its far smaller execution resource pool, as the compute ratios above make clear.

The A380E x2 uses 1024 shading units, 64 TMUs, and 32 ROPs. The mobile part uses 128 shading units, 8 TMUs, and 4 ROPs. That is an 8:1 ratio in shading units, an 8:1 ratio in TMUs, and an 8:1 ratio in ROPs. The RT core count is 8 for the A380E x2 versus 1 for the mobile part, also an 8:1 ratio. These resource ratios align with the compute throughput ratios, confirming that the A380E x2 is essentially eight times the execution engine of the mobile part in every parallel unit category.

Neither part has any recorded benchmark wins in the head-to-head table, so winsA and winsB are both 0. The verdict must therefore rest on theoretical peak figures and hardware specifications, not on observed performance data. The database shows no scenario where the mobile part is faster in a measured benchmark, because no benchmarks exist for either part.

The Verdict

Based strictly on the recorded data, the Intel Arc A380E x2 is the faster part in every computable metric. It delivers 4.096 TFLOPS FP32 versus 588.8 GFLOPS for the mobile chip, 64.00 GPixel/s versus 9.200 GPixel/s, and 128.0 GTexel/s versus 18.40 GTexel/s. The A380E x2 also has 6 GB of dedicated GDDR6 with 186.0 GB/s bandwidth, whereas the mobile part relies on system shared memory with no fixed bandwidth figure. The mobile part has a higher boost clock at 2300 MHz versus 2000 MHz, and it uses a newer 3 nm Intel process node versus 6 nm TSMC, but neither advantage changes the compute outcome.

The Intel Arc Graphics 1 Xe Mobile is the part for a system where power and physical footprint dominate. Its 25 W TDP sits far below the A380E x2's 130 W TDP. The mobile part is an IGP with no power connectors and no slot width, while the A380E x2 is a single-slot card requiring a 1x 6-pin connector and a 300 W suggested PSU. The mobile part also uses a newer architecture, Xe3-LPG on Wildcat Lake, versus Xe-HPG on DG2-128 for the A380E x2.

Users who need a discrete GPU with dedicated memory, eight display outputs, and roughly seven times the FP32 throughput should select the A380E x2. Users who need an integrated graphics solution for a portable device, with minimal power draw and no add-in card footprint, should select the mobile part. The data does not support any claim that the mobile part outperforms the A380E x2 in raw graphics work, but its role is entirely different.

Where Each One Wins

The Intel Arc A380E x2 wins in every raw performance category recorded in the database. It holds a roughly 7x lead in FP32 throughput, FP16 throughput, pixel fill rate, and texture fill rate. It offers dedicated 6 GB GDDR6 memory with 186.0 GB/s bandwidth, which removes dependence on system memory performance. It provides 8 display outputs via mini-DisplayPort 2.0, making it suited for multi-display or embedded visual systems. Its 130 W TDP and single-slot form factor fit a desktop or industrial chassis with a 300 W PSU and one 6-pin connector.

The Intel Arc Graphics 1 Xe Mobile wins in power efficiency and integration. Its 25 W TDP is roughly one-fifth the A380E x2's 130 W TDP, though the database does not record a direct efficiency metric. It requires no power connectors, no slot width, and no separate PSU, since it is an IGP with a bus interface listed as IGP. Its 3 nm Intel process node is newer than the 6 nm TSMC node of the A380E x2. Its higher 2300 MHz boost clock gives it a clock speed advantage when active, and its base clock of 300 MHz allows very low idle power states. It is listed as active production, while the A380E x2 is end-of-life.

In practical terms, the mobile part suits portable devices where a discrete card cannot physically fit and where system shared memory is acceptable. The A380E x2 suits systems that need sustained compute throughput, dedicated memory bandwidth, and multiple display outputs. The database does not provide any benchmark result where the mobile part outperforms the A380E x2, and the compute ratios overwhelmingly favor the A380E x2 for graphics workloads. The mobile part's wins are limited to power draw, physical integration, process node, and production status.
