Intel Arc A380E vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The Verdict

The Intel Arc A380E and the NVIDIA GeForce RTX 5070 Ti Mobile occupy opposite ends of the GPU spectrum. The Arc A380E is an end-of-life, entry-level discrete card for compact systems, while the RTX 5070 Ti Mobile is an active, high-end laptop GPU. The recorded data shows the RTX 5070 Ti Mobile delivers roughly four times the FP32 compute throughput, nearly four times the memory bandwidth, and sits at the 80th percentile of all GPUs in the database, compared to the A380E's 50th percentile. The RTX 5070 Ti Mobile has an average benchmark score of 35,435, placing it within 2.4% of the NVIDIA T1000 and 1.2% of the AMD Radeon Pro Duo, while the Arc A380E has no recorded benchmark scores or rival comparisons in the database.

The A380E is for a very narrow use case: a low-profile, single-slot card that draws 75 W and needs no auxiliary power connectors. Its 4x DisplayPort 2.0 outputs and 6 GB of GDDR6 make it a plausible multi-display output card for a workstation or server where rendering performance is secondary. The RTX 5070 Ti Mobile is for anyone who needs actual compute and gaming capability in a laptop. Its 12 GB of GDDR7, 184 tensor cores, and 46 ray tracing cores put it in a different performance class entirely. The data does not support any scenario where the A380E is the better pick for conventional 3D workloads.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The Intel Arc A380E uses the DG2-128 chip built on Xe-HPG architecture, part of the Alchemist (Arc 3) generation, fabricated by TSMC on a 6 nm process. It packs 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation, also fabricated by TSMC but on a 5 nm process. It contains 31,100 million transistors on a 263 mm² die, with a density of 118.3 million per square millimeter. The NVIDIA chip has more than four times the transistor count on a die that is only about 67% larger.

The compute resources differ massively. The A380E has 1,024 shading units, 64 texture mapping units, 32 raster output units, and 8 ray tracing cores. It has no tensor cores. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. The FP32 throughput tells the story: the A380E manages 4.096 TFLOPS, while the RTX 5070 Ti Mobile delivers 17.04 TFLOPS. FP16 performance also diverges, with the A380E at 8.192 TFLOPS using a 2:1 ratio versus the NVIDIA part's 17.04 TFLOPS at a 1:1 ratio, meaning the NVIDIA GPU does not rely on packed math to reach its FP16 number.

The memory subsystems are equally different. The A380E uses 6 GB of GDDR6 on a 96-bit bus, running at 1937 MHz (15.5 Gbps effective), providing 186.0 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, running at 1750 MHz (28 Gbps effective), providing 672.0 GB/s. That is a 3.6x bandwidth advantage for the NVIDIA part. The A380E connects via PCIe 4.0 x8, while the RTX 5070 Ti Mobile uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A380E outputs to 4x DisplayPort 2.0, while the mobile NVIDIA part's display outputs are marked as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two GPUs, and the Arc A380E has no individual benchmark scores recorded. The RTX 5070 Ti Mobile, however, has a full suite of results. Its Geekbench OpenCL score is 143,870, and its Geekbench Vulkan score is 139,213. Passmark results span multiple DirectX versions: DirectX 10 at 151, DirectX 11 at 237, DirectX 12 at 102, and DirectX 9 at 259. The 2D score is 981, the 3D score is 24,004, and the GPU compute score is 10,101. The average benchmark score across all recorded tests is 35,435.

Because the A380E has no benchmark entries, the only quantitative comparison available is through the RTX 5070 Ti Mobile's nearest rivals. The NVIDIA part scores 0.2% below the NVIDIA Quadro GV100 (35,520), 1.2% below the AMD Radeon Pro Duo (35,860), 2.1% above the NVIDIA A2 (34,690), and 2.4% below the NVIDIA T1000 (36,289). These deltas are all small, placing the RTX 5070 Ti Mobile firmly in a competitive band with those professional GPUs. The A380E's FP32 rate of 4.096 TFLOPS versus the RTX 5070 Ti Mobile's 17.04 TFLOPS suggests the Intel part would trail by a factor of roughly 4.2 in raw shader throughput, but without direct test data, that remains an inference from specifications rather than a measured result.

The pixel and texture rates reinforce the gap. The A380E produces 64.00 GPixel/s and 128.0 GTexel/s. The RTX 5070 Ti Mobile produces 115.8 GPixel/s and 266.2 GTexel/s. The NVIDIA GPU is roughly 1.8x faster at pixel fill and 2.1x faster at texture fill. These are derived rates from clock and unit counts, not application scores, but they indicate where the architectural advantage lies.

Where Each One Wins

The RTX 5070 Ti Mobile wins every measurable performance category in the database. Its FP32 compute is 4.2x higher, its texture rate is 2.1x higher, its pixel rate is 1.8x higher, and its memory bandwidth is 3.6x higher. Its 184 tensor cores enable AI and machine learning workloads that the A380E cannot attempt. Its 46 RT cores provide hardware ray tracing capability that scales well beyond the A380E's 8 RT cores. The 12 GB VRAM capacity doubles the A380E's 6 GB, which matters for large datasets, high-resolution textures, and modern game assets. The 80th percentile ranking versus the A380E's 50th percentile puts the NVIDIA part in a different performance tier altogether.

The A380E's wins are in form factor and output flexibility, not raw speed. It is a single-slot card measuring 254 mm by 127 mm by 20 mm, which fits in chassis that cannot accommodate larger GPUs. It requires no power connectors and runs on a 75 W TDP, making it easy to slot into existing systems with a 250 W power supply. Its 4x DisplayPort 2.0 outputs are a concrete advantage for multi-monitor setups; the RTX 5070 Ti Mobile's display outputs are portable device dependent, meaning the OEM laptop dictates what ports exist. For a system that needs many high-bandwidth display outputs from a low-power card, the A380E has a purpose. For any task that involves rendering, gaming, compute, or AI, the RTX 5070 Ti Mobile dominates.
