Intel Arc A380E vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the Intel Arc A380E and the NVIDIA GeForce RTX 4080 Mobile. The RTX 4080 Mobile holds a clear advantage across every measurable dimension, with no benchmark wins recorded for the Arc A380E. The database lists zero wins for the Intel part and zero wins for the NVIDIA part in head-to-head comparisons, but the underlying specifications and the RTX 4080 Mobile's benchmark scores paint an unambiguous picture.

The NVIDIA GeForce RTX 4080 Mobile delivers a Geekbench OpenCL score of 159,575 and a Geekbench Vulkan score of 145,807. These are substantial figures that place the GPU in the 81st percentile of all GPUs in the database. The Arc A380E, by contrast, has no recorded benchmark scores and sits at the 50th percentile. The RTX 4080 Mobile's average benchmark score is 38,135, and its nearest rivals in the database include the NVIDIA GeForce MX570 at 38,299 (0.4% ahead), the NVIDIA GeForce RTX 5080 Mobile at 38,349 (0.6% ahead), the NVIDIA GeForce RTX 4070 at 37,648 (1.3% behind), and the NVIDIA Tesla P4 at 37,628 (1.3% behind). This clustering shows the RTX 4080 Mobile is competitive with a tight group of high-end GPUs, while the Arc A380E has no comparable data points.

In compute-oriented workloads, the RTX 4080 Mobile records a PassMark GPU Compute score of 11,191. For DirectX 12, it scores 96, for DirectX 11 it reaches 244, and for DirectX 10 it posts 157. DirectX 9 performance is the strongest legacy result at 286. The 2D graphics score is 929, and the overall 3D graphics score is 24,926. These numbers reflect a GPU that is built for sustained high-load rendering and compute tasks. The Arc A380E, with no recorded benchmarks, cannot be positioned against these numbers beyond its theoretical specifications.

The FP32 throughput differential is stark. The RTX 4080 Mobile delivers 24.72 TFLOPS of FP32 compute, while the Arc A380E delivers 4.096 TFLOPS. That is roughly six times the raw floating-point throughput. Texture rate follows the same pattern: 386.3 GTexel/s for the NVIDIA part versus 128.0 GTexel/s for the Intel part. Pixel rate is 133.2 GPixel/s versus 64.00 GPixel/s. The RTX 4080 Mobile also has a massive lead in shading units, with 7,424 compared to 1,024, and in RT cores, with 58 versus 8.

Memory bandwidth is another major separator. The RTX 4080 Mobile uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The Arc A380E has 6 GB of GDDR6 on a 96-bit bus, yielding 186.0 GB/s. The NVIDIA part offers more than double the memory capacity and more than double the bandwidth. The Arc A380E does have a higher base clock at 2000 MHz versus 1290 MHz, and its boost clock matches its base at 2000 MHz, while the RTX 4080 Mobile boosts to 1665 MHz. Clock speed alone does not compensate for the massive differences in core counts and memory subsystem.

The Verdict

The data indicates the NVIDIA GeForce RTX 4080 Mobile is the superior GPU for essentially every workload captured in the database. It has a 24.72 TFLOPS FP32 figure, 432.0 GB/s of memory bandwidth, and a PassMark G3D score of 24,926. The Intel Arc A380E, with 4.096 TFLOPS, 186.0 GB/s bandwidth, and no recorded benchmark scores, is positioned for entirely different use cases. The Arc A380E's 50th percentile ranking and end-of-life production status place it as a low-power, entry-level discrete GPU. The RTX 4080 Mobile's 81st percentile ranking and its proximity to the RTX 5080 Mobile and RTX 4070 in average scores confirm it belongs to the high-performance mobile segment.

Users who need maximum rendering performance, high refresh rate gaming, or heavy GPGPU compute should select the RTX 4080 Mobile. The 12 GB memory pool and 58 RT cores make it suitable for modern game workloads and ray-traced content. Users who require a low-power, single-slot GPU with a 75 W TDP and no external power connectors should consider the Arc A380E. The Intel part draws 75 W versus 110 W for the NVIDIA part, and it is a single-slot design measuring 254 mm in length, 127 mm in height, and 20 mm in width. The RTX 4080 Mobile is an IGP (integrated graphics processor for mobile) with dimensions listed as portable device dependent. The Arc A380E is an end-of-life product, while the RTX 4080 Mobile is active.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc A380E uses the Xe-HPG architecture on the DG2-128 chip, part of the Alchemist generation under the Arc 3 series. The NVIDIA GeForce RTX 4080 Mobile uses the Ada Lovelace architecture on the AD104 chip, part of the GeForce 40 Mobile generation. Both are built by TSMC, but on different nodes: the Intel part uses a 6 nm process, while the NVIDIA part uses a 5 nm process. The transistor counts differ substantially. The Arc A380E has 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. The RTX 4080 Mobile has 35,800 million transistors on a 294 mm² die, yielding 121.8 million per square millimeter. The NVIDIA chip packs nearly five times the transistor count into less than double the die area.

The RTX 4080 Mobile includes 232 tensor cores, a feature entirely absent from the Arc A380E's specifications. This makes the NVIDIA part capable of AI-accelerated workloads that the Intel part cannot address through dedicated tensor hardware. The RTX 4080 Mobile also integrates 58 RT cores versus 8 on the Arc A380E, a significant difference for ray-traced rendering. The Arc A380E's RT core count is low enough to suggest only minimal ray-tracing capability.

FP16 compute differs in implementation. The Arc A380E reaches 8.192 TFLOPS at a 2:1 ratio relative to FP32, while the RTX 4080 Mobile achieves 24.72 TFLOPS at a 1:1 ratio. The NVIDIA part does not sacrifice half-precision throughput, which matters for mixed-precision compute workloads. The Intel part halves its FP16 rate, indicating a more limited compute feature set.

Where Each One Wins

The NVIDIA GeForce RTX 4080 Mobile wins in every performance category captured in the database. Its 24.92% higher passmark G3D score of 24,926 versus no recorded score for the Arc A380E, its 11,191 GPU compute score, and its 159,575 OpenCL score all point to a GPU designed for high-end gaming and professional workloads. The 432.0 GB/s bandwidth and 12 GB memory capacity give it substantial headroom for large textures, high-resolution assets, and compute datasets. The 58 RT cores and 232 tensor cores make it the clear choice for ray-traced games and AI-accelerated applications. The 81st percentile ranking places it among the top tier of GPUs in the database.

The Intel Arc A380E wins in power efficiency and physical design. Its 75 W TDP is lower than the 110 W TDP of the RTX 4080 Mobile. It is a single-slot card with fixed dimensions of 254 mm length, 127 mm height, and 20 mm width, and it requires no power connectors. It provides 4x DisplayPort 2.0 outputs, which is a fixed, known configuration, whereas the RTX 4080 Mobile's outputs depend on the portable device. The Arc A380E uses a PCIe 4.0 x8 interface, which is sufficient for its bandwidth requirements. For systems with strict power budgets, limited space, or a need for a dedicated low-profile GPU, the Arc A380E is the only viable option between the two. Its 50th percentile ranking indicates mid-pack performance among all GPUs, sufficient for basic rendering and display tasks but not for demanding 3D workloads. The RTX 4080 Mobile, with its 110 W TDP and IGP form factor, is meant for laptops and portable devices where the chassis handles cooling and power delivery. The choice between the two depends entirely on the target platform: mobile high-performance systems favor the RTX 4080 Mobile, while compact, low-power desktop builds favor the Arc A380E.
