Intel Arc 140V Mobile vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the Intel Arc 140V Mobile or the Intel Arc A380E. Both entries show an average benchmark score of zero and no listed head-to-head results. Consequently, a numeric comparison of performance deltas between these two parts cannot be derived from the available data.

Both GPUs occupy the 50th percentile against all GPUs in the database, indicating that their overall standing in the broader performance distribution is identical, at least as far as the recorded percentile metric is concerned. The absence of benchmark data means that any performance ranking between them must be inferred from their architectural specifications and feature sets rather than from direct measurements.

The lack of wins assigned to either part (zero wins each) further confirms that no validated comparison exists in the database. This is not a case of one part dominating the other; it is a case where the database simply has not recorded comparative performance results for these two Intel graphics products.

Architecture Differences

The Intel Arc 140V Mobile is built on the Lunar Lake chip and uses the Xe2-LPG architecture, which represents Intel's second-generation Xe graphics design. It is fabricated on a 3 nm process node at TSMC. The Intel Arc A380E, by contrast, uses the DG2-128 chip and the Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. The A380E is manufactured on a 6 nm process node, also at TSMC.

The process node difference is significant: the 140V Mobile uses a 3 nm process, while the A380E uses a 6 nm process. This indicates that the mobile part is built on a more advanced manufacturing technology, which typically allows for higher transistor density and lower power consumption at equivalent performance levels.

Transistor counts differ as well. The A380E integrates 7,200 million transistors on a die size of 157 mm², yielding a transistor density of 45.9 million transistors per square millimeter. The 140V Mobile's transistor count is listed as unknown, but its die size is recorded as 172 mm². Without a transistor figure for the 140V Mobile, direct density calculations are not possible from the database.

The 140V Mobile is an integrated graphics processor (IGP), meaning it is part of the host processor package and shares system memory. The A380E is a discrete, single-slot add-in card with its own dedicated memory. This fundamental packaging difference drives many of the other specification gaps.

Where Each One Wins

The Intel Arc 140V Mobile wins in the context of power efficiency and system integration. Its TDP is recorded at 37 W, whereas the A380E consumes 75 W. For mobile devices, where thermal and power budgets are constrained, the 140V Mobile's lower power draw is a clear advantage. It is also an IGP with a bus interface of "IGP," meaning it requires no separate power connectors and no additional slot. The A380E, while also lacking power connectors, requires a 250 W suggested power supply and occupies a single slot in a chassis.

The A380E wins in the context of memory bandwidth and capacity. It has 6 GB of dedicated GDDR6 memory on a 96-bit bus, delivering 186.0 GB/s of bandwidth. The 140V Mobile uses system shared memory, with bandwidth described as "System Dependent." In workloads that are sensitive to memory bandwidth, such as high-resolution texture streaming or certain compute tasks, the A380E's fixed, dedicated memory subsystem provides a more predictable performance envelope.

In raw compute throughput, the A380E holds a slight edge based on clock speeds. Its base and boost clocks are both 2000 MHz, while the 140V Mobile has a base clock of 300 MHz and a boost clock of 1950 MHz. The A380E's pixel rate is 64.00 GPixel/s versus 62.40 GPixel/s for the 140V Mobile. Its texture rate is 128.0 GTexel/s versus 124.8 GTexel/s. FP32 performance is 4.096 TFLOPS for the A380E versus 3.994 TFLOPS for the 140V Mobile. FP16 performance is 8.192 TFLOPS versus 7.987 TFLOPS. In every one of these throughput metrics, the A380E records a higher number, though the margins are modest, ranging from roughly 1.3% to 2.6%.

The 140V Mobile wins on production status: it is listed as Active, while the A380E is End-of-life. The A380E has a listed successor, Battlemage, whereas the 140V Mobile does not yet have a successor in the database.

Specification Differences

The two parts differ across several specification fields. The 140V Mobile uses a 3 nm process node; the A380E uses 6 nm. The A380E has a recorded transistor count of 7,200 million and a density of 45.9M per mm²; the 140V Mobile's transistor count is unknown. Die size is 172 mm² for the 140V Mobile and 157 mm² for the A380E.

Clock speeds differ substantially. The 140V Mobile has a base clock of 300 MHz and a boost clock of 1950 MHz. The A380E has a fixed clock of 2000 MHz for both base and boost. The A380E's memory clock is 1937 MHz with 15.5 Gbps effective speed.

Memory configuration is entirely different. The 140V Mobile uses System Shared memory with a System Shared bus width and System Dependent bandwidth. The A380E has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth.

Shading units, texture mapping units, and raster output units are identical: 1024 shading units, 64 TMUs, and 32 ROPs for both. Ray tracing cores are also the same at 8 for each part.

Pixel rate, texture rate, FP32, and FP16 performance all favor the A380E by small margins, as detailed in the previous section.

TDP is 37 W for the 140V Mobile and 75 W for the A380E. The 140V Mobile is an IGP with an IGP bus interface; the A380E is Single-slot with a PCIe 4.0 x8 interface. The A380E has no power connectors but a 250 W suggested PSU; the 140V Mobile has no power connector fields applicable.

Display outputs differ: the 140V Mobile is "Portable Device Dependent," while the A380E offers 4x DisplayPort 2.0.

Dimensions are only recorded for the A380E: 254 mm length, 127 mm height, and 20 mm width.

Release dates differ: the 140V Mobile launched on 2024-09-23, while the A380E launched on 2024-03-31. The A380E is End-of-life with a successor named Battlemage; the 140V Mobile is Active with no successor. A380E's predecessor is Xe Graphics; 140V Mobile's predecessor is HD Graphics-M.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates that the Intel Arc A380E is the stronger part in raw compute metrics. It exceeds the 140V Mobile in pixel rate (64.00 GPixel/s vs 62.40 GPixel/s), texture rate (128.0 GTexel/s vs 124.8 GTexel/s), FP32 throughput (4.096 TFLOPS vs 3.994 TFLOPS), and FP16 throughput (8.192 TFLOPS vs 7.987 TFLOPS). It also has a higher boost clock (2000 MHz vs 1950 MHz) and dedicated GDDR6 memory with 186.0 GB/s bandwidth, which is a significant advantage for memory-bound workloads. However, these performance gains come with a TDP of 75 W, double the 37 W of the 140V Mobile, and the A380E is End-of-life, with a successor already identified.

The Intel Arc 140V Mobile is the appropriate choice for mobile and integrated system designs where power consumption is critical. Its 3 nm process node, lower TDP, and IGP form factor make it suitable for portable devices where the A380E's discrete card footprint and higher power draw are impractical. The 140V Mobile is Active in production, ensuring ongoing availability.

For users who need a discrete, single-slot GPU with dedicated memory and consistent bandwidth, the A380E provides modestly higher throughput across every recorded compute metric. But the A380E's End-of-life status and higher power requirements mean it is a legacy option. The 140V Mobile, despite lower raw numbers, offers a modern, efficient alternative that matches the A380E in core counts, ray tracing cores, and API support. The choice between the two should be guided by the target system's form factor and power constraints, with the A380E favored for standalone graphics tasks and the 140V Mobile favored for integrated mobile applications.
