Intel Arc 140T Mobile vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the Intel Arc 140T Mobile and the Intel Arc A380E x2. Both entries show zero wins in matched testing, and no benchmark scores are available for either part. This absence of comparative data is itself informative. It suggests these two GPUs occupy different evaluation tracks within the database, one tied to mobile integration and the other to discrete embedded deployment.

The Intel Arc 140T Mobile carries an average benchmark score of 0 and sits at the 50th percentile against all GPUs. The Intel Arc A380E x2 also posts an average benchmark score of 0 and matches the same 50th percentile ranking. With no nearest rivals listed for either product, the database currently lacks a reference frame to position these parts against other discrete or integrated accelerators. The equal percentile rank indicates both are positioned near the median of the recorded GPU population, but the absence of scored runs means the percentile is a placeholder rather than a measured outcome.

What can be compared directly are the raw throughput ceilings derived from their clock and unit specifications. The Arc 140T Mobile reaches 75.20 GPixel/s of pixel fill rate and 150.4 GTexel/s of texture rate. The Arc A380E x2 delivers 64.00 GPixel/s and 128.0 GTexel/s. The mobile part leads by 11.20 GPixel/s in pixel throughput and by 22.4 GTexel/s in texture throughput.

Architecture Differences

The two GPUs stem from different Intel architectures and manufacturing processes. The Arc 140T Mobile uses the Arrow Lake-H chip built on the Xe-LPG+ architecture, fabricated on a 5 nm process at TSMC. It belongs to the Arc Graphics-M (Arrow Lake) generation. The Arc A380E x2 uses the DG2-128 chip built on the Xe-HPG architecture, fabricated on a 6 nm process at TSMC. It belongs to the Alchemist (Arc 3) generation.

The Xe-LPG+ architecture in the mobile part is designed for integrated graphics within a processor package. It operates as an IGP with no slot width, no power connectors, and a 35 W TDP. The Xe-HPG architecture in the discrete part is designed as a standalone accelerator. It occupies a single-slot form factor, requires a 6-pin power connector, and carries a 130 W TDP. The bus interface differs accordingly: the Arc 140T Mobile uses IGP, while the Arc A380E x2 uses PCIe 4.0 x8.

The transistor counts and die sizes are only recorded for the A380E x2. It contains 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9M per mm². The Arc 140T Mobile has unknown transistor count and die size in the database, so no die-level comparison is possible.

Display output capabilities also diverge. The Arc 140T Mobile relies on portable device dependent outputs, reflecting its integration into laptops and mobile systems. The Arc A380E x2 provides 8x mini-DisplayPort 2.0 outputs, suited for multi-display embedded or edge deployments.

The production lifecycle differs as well. The Arc 140T Mobile is Active, released on 2025-01-12, with a predecessor of HD Graphics-M. The Arc A380E x2 is End-of-life, released on 2024-03-31, with a predecessor of Xe Graphics and a successor of Battlemage.

Specification Differences

Clock speeds differ substantially. The Arc 140T Mobile has a 300 MHz base clock and a 2350 MHz boost clock. The Arc A380E x2 has a fixed 2000 MHz clock for both base and boost. The memory clock also differs: the mobile part uses system shared memory, while the discrete part runs at 1937 MHz (15.5 Gbps effective).

Memory configuration shows the largest gap. The Arc 140T Mobile has system shared memory with system dependent bandwidth. The Arc A380E x2 has 6 GB of GDDR6, a 96-bit bus, and 186.0 GB/s bandwidth.

Power delivery differs. The Arc 140T Mobile draws a 35 W TDP with no power connectors. The Arc A380E x2 draws a 130 W TDP, requires one 6-pin power connector, and carries a 300 W suggested PSU rating.

Physical dimensions are recorded only for the discrete part. The Arc A380E x2 measures 265 mm (10.4 inches) in length, 127 mm (5 inches) in height, and 20 mm (0.8 inches) in width. The mobile part has no recorded dimensions, consistent with its IGP status.

Process node differs: 5 nm for the Arc 140T Mobile versus 6 nm for the Arc A380E x2. Transistor count, die size, and transistor density are unknown for the mobile part but recorded as 7,200 million transistors, 157 mm², and 45.9M per mm² for the discrete part.

Compute rates differ across all measured metrics. The Arc 140T Mobile posts 75.20 GPixel/s pixel rate and 150.4 GTexel/s texture rate. The Arc A380E x2 posts 64.00 GPixel/s and 128.0 GTexel/s. FP32 and FP16 throughput also favor the mobile part, as detailed in the head-to-head section.

Release timing and status differ. The Arc 140T Mobile released on 2025-01-12 and remains Active. The Arc A380E x2 released on 2024-03-31 and is End-of-life.

Where Each One Wins

The Arc 140T Mobile wins on raw compute throughput and efficiency metrics. Its 4.813 TFLOPS FP32 and 9.626 TFLOPS FP16 exceed the discrete part by 0.717 and 1.434 TFLOPS respectively. Its pixel rate of 75.20 GPixel/s and texture rate of 150.4 GTexel/s also lead the A380E x2. The 35 W TDP compared to 130 W means the mobile part delivers higher throughput per watt, a decisive factor in thermally constrained mobile chassis. Its 5 nm process node gives it a manufacturing advantage over the 6 nm discrete part. The 2350 MHz boost clock also exceeds the fixed 2000 MHz clock of the discrete GPU.

The Arc A380E x2 wins on memory resources and deployment flexibility. Its 6 GB of dedicated GDDR6 memory with 186.0 GB/s bandwidth is fixed and predictable, unlike the system dependent bandwidth of the shared-memory mobile part. This makes it suitable for workloads where memory allocation cannot compete with other system components. The 8x mini-DisplayPort 2.0 outputs support multi-display configurations that the portable device dependent outputs of the Arc 140T Mobile cannot guarantee. The PCIe 4.0 x8 interface provides a standard discrete connection path, while the IGP bus of the mobile part ties it to the host processor's integrated design. The single-slot form factor and 265 mm length allow installation in standard expansion slots, whereas the mobile part has no slot width and cannot be installed as a standalone card. The 130 W TDP, while higher, enables sustained operation in systems with adequate power delivery.

The A380E x2 also holds an advantage in historical context. It is End-of-life with a documented successor (Battlemage), meaning its specifications are fully settled. The Arc 140T Mobile is Active with no successor listed, so its long-term positioning remains open.

The Verdict

The data supports a clear split by use case. The Intel Arc 140T Mobile is the stronger compute performer. Its higher FP32 and FP16 throughput, faster pixel and texture rates, and superior process node make it the better choice for compute-focused workloads within a mobile platform. The 35 W TDP confirms it is engineered for power-sensitive environments where the 130 W discrete part would be impractical. Its Active production status also indicates ongoing availability and support.

The Intel Arc A380E x2 is the stronger memory and deployment option. Its 6 GB dedicated GDDR6 with 186.0 GB/s bandwidth removes memory sharing uncertainty. The 8x mini-DisplayPort 2.0 outputs and single-slot form factor suit fixed installations requiring multiple displays. The PCIe 4.0 x8 interface allows standard integration into discrete GPU slots. For systems needing predictable memory behavior and multi-display output, the A380E x2 is the only choice between the two.

Buyers selecting between these parts should base the decision on form factor and memory requirements. A mobile or compact system with shared memory and limited power budget aligns with the Arc 140T Mobile. A discrete, multi-display embedded system with dedicated memory aligns with the Arc A380E x2. The compute advantage of the mobile part is real but modest in percentage terms, while the memory and connectivity advantages of the discrete part are categorical. No head-to-head benchmark data exists to override these specification-driven conclusions.
