Intel Arc A380E vs NVIDIA RTX 500 Mobile Ada Generation Comparison

Intel Arc A380E and NVIDIA RTX 500 Mobile Ada Generation occupy opposite ends of the GPU spectrum, yet both target compact, low-power systems. The Arc A380E is a desktop-oriented, end-of-life part from Intel’s Alchemist generation, while the RTX 500 Mobile is an active, integrated-class mobile GPU from NVIDIA’s Ada Lovelace line. The recorded data shows two very different design philosophies: Intel delivers more memory and a wider bus, while NVIDIA packs nearly double the shading units and raw compute into a 35 W envelope. The database places both at the 50th percentile among all GPUs, meaning they sit in the middle of the performance distribution, but the underlying specifications suggest they achieve that standing through different means.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database is empty, so there are no direct frame-rate comparisons or synthetic scores to reference. Both parts instead rely on their specification sheets, and those reveal a clear split. The most striking difference is raw compute. The RTX 500 Mobile delivers 8.294 TFLOPS of FP32 performance, which is 4.198 TFLOPS higher than the Arc A380E’s 4.096 TFLOPS. In percentage terms, the NVIDIA part is 104.8% ahead in FP32 throughput. That is a dominant lead in the metric most often associated with general rendering and compute workloads. The RTX 500 Mobile achieves this with 2048 shading units, exactly twice the 1024 shading units on the Arc A380E. Clock speeds tell part of the story: the NVIDIA part boosts to 2025 MHz, while the Intel part holds a steady 2000 MHz. The higher clock, combined with the doubled shader count, explains the FP32 gap almost entirely.

Memory, however, flips the script. The Arc A380E ships with 6 GB of GDDR6 on a 96-bit bus, producing 186.0 GB/s of bandwidth. The RTX 500 Mobile has 4 GB of GDDR6 on a 64-bit bus, yielding 128.0 GB/s. The Intel part is 45.3% ahead in memory bandwidth, a substantial margin that matters in texture-heavy scenes, high-resolution buffers, and any workload that saturates memory throughput. The Arc A380E also runs its memory at 1937 MHz (15.5 Gbps effective) versus 2000 MHz (16 Gbps effective) on the NVIDIA part, but the wider bus more than compensates for the slightly lower memory clock. Pixel and texture rates are nearly identical: the Arc A380E posts 64.00 GPixel/s and 128.0 GTexel/s, while the RTX 500 Mobile posts 64.80 GPixel/s and 129.6 GTexel/s. The NVIDIA part leads by 1.2% in pixel rate and by 1.25% in texture rate, margins so small they are effectively negligible for real-world workloads. The data indicates that rasterization throughput at the pixel and texture level is a wash, while compute and memory move in opposite directions.

The architecture differences also show up in ray tracing and AI acceleration. The RTX 500 Mobile includes 16 ray tracing cores and 64 tensor cores, while the Arc A380E includes 8 ray tracing cores and no tensor cores at all. The RTX 500 Mobile has 8 more RT cores and 64 more tensor cores, giving it a clear hardware advantage in ray-traced rendering and AI-assisted features like DLSS. The Arc A380E has no equivalent to the tensor core array, so any AI or deep-learning workload would rely on its FP16 capabilities, which reach 8.192 TFLOPS at a 2:1 ratio. The RTX 500 Mobile matches its FP32 rate in FP16 at 8.294 TFLOPS with a 1:1 ratio, so the NVIDIA part leads there too, though by a smaller 1.2% margin. In pure FP16 throughput, the two are close, but the tensor cores give the RTX 500 Mobile a dedicated path for AI workloads that the Intel part cannot match.

Where Each One Wins

The Arc A380E wins where memory capacity and memory bandwidth dominate. Its 6 GB frame buffer is 50% larger than the RTX 500 Mobile’s 4 GB, which allows it to hold larger textures, more geometry, and higher-resolution render targets without spilling to system memory. The bandwidth advantage of 186.0 GB/s versus 128.0 GB/s is a 45.3% lead, and that directly benefits workloads that stream large amounts of data, such as 4K textures, compute shaders that read and write big buffers, and multi-display setups with high resolutions. The Arc A380E also offers four DisplayPort 2.0 outputs, while the RTX 500 Mobile’s display outputs are described as portable-device dependent. For a fixed desktop workstation or a multi-monitor configuration, the Intel part provides a standardized, high-bandwidth display interface without relying on the host laptop’s panel wiring.

The RTX 500 Mobile wins where raw compute, ray tracing, and power efficiency matter. Its FP32 throughput of 8.294 TFLOPS is more than double the Arc A380E’s 4.096 TFLOPS, so any shader-bound workload, physics simulation, or general-purpose compute task will complete faster on the NVIDIA part. The 16 RT cores versus 8 provide a 2x hardware count for ray-traced effects, and the 64 tensor cores enable AI acceleration features that the Intel part lacks entirely. The RTX 500 Mobile also operates within a 35 W TDP, less than half of the Arc A380E’s 75 W TDP. The data shows that the NVIDIA part delivers 0.237 TFLOPS per watt, while the Intel part delivers 0.055 TFLOPS per watt. That is a 4.3x efficiency advantage for the RTX 500 Mobile, a decisive factor for laptops, compact systems, and battery-powered devices where thermal headroom is scarce. The RTX 500 Mobile is also an integrated form factor (IGP), meaning it is designed to be soldered onto a motherboard, while the Arc A380E is a single-slot, 254 mm long add-in card that requires a 250 W suggested power supply.

Architecture Differences

The two GPUs come from different process nodes and different architectural generations. The Arc A380E uses Intel’s Xe-HPG architecture, specifically the DG2-128 chip, built on TSMC’s 6 nm process. The RTX 500 Mobile uses NVIDIA’s Ada Lovelace architecture, with the AD107 chip, built on TSMC’s 5 nm process. The smaller process node gives the NVIDIA part a density advantage: the AD107 packs 18,900 million transistors into a 159 mm² die, for a transistor density of 118.9 million per square millimeter. The DG2-128 packs 7,200 million transistors into a 157 mm² die, for a density of 45.9 million per square millimeter. That is a 2.6x difference in transistor density, which explains how the RTX 500 Mobile fits 2048 shading units, 16 RT cores, and 64 tensor cores into a 35 W power budget while the Arc A380E uses 75 W for half the shading units and fewer RT cores.

The memory subsystems reflect different priorities. The Arc A380E uses a 96-bit bus with 6 GB of GDDR6, while the RTX 500 Mobile uses a 64-bit bus with 4 GB of GDDR6. The Intel part’s wider bus is its primary lever for bandwidth, and the database shows 186.0 GB/s versus 128.0 GB/s. The memory clock on the NVIDIA part is higher at 2000 MHz (16 Gbps effective) versus 1937 MHz (15.5 Gbps effective), but the narrower bus negates that advantage. The Arc A380E’s 6 GB capacity suggests a target of 1080p gaming or professional workloads with moderate texture sizes, while the RTX 500 Mobile’s 4 GB is more constrained for modern game assets but sufficient for its intended mobile, efficiency-focused role.

The feature sets diverge significantly in compute accelerators. The RTX 500 Mobile has 16 ray tracing cores and 64 tensor cores, while the Arc A380E has 8 ray tracing cores and no tensor cores. The RTX 500 Mobile’s FP16 throughput is 8.294 TFLOPS at a 1:1 ratio with FP32, meaning it does not rely on a rate-halving scheme. The Arc A380E reaches 8.192 TFLOPS in FP16 but only at a 2:1 ratio, so its FP16 performance is effectively half its FP32 rate per clock. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical. The bus interface is the same for both: PCIe 4.0 x8. Neither GPU requires external power connectors; the Arc A380E draws its power from the PCIe slot plus a 250 W suggested power supply, while the RTX 500 Mobile, as an IGP, draws power from the motherboard’s allocation for the mobile platform.

The physical and production profiles differ starkly. The Arc A380E is a 254 mm long, 127 mm high, 20 mm wide single-slot card with four DisplayPort 2.0 outputs. It is marked end-of-life, with a release date in March 2024, and its predecessor and successor are listed as Xe Graphics and Battlemage, respectively. The RTX 500 Mobile has no listed dimensions, no independent display outputs (portable-device dependent), and is marked active, with a release date in February 2024. Its predecessor is Ampere-MW and its successor is Blackwell-MW. The Intel part is a standalone desktop component; the NVIDIA part is a mobile chip designed to be integrated into a laptop or compact device.

The RTX 500 Mobile is the stronger compute device, with more than double the FP32 throughput, a 2x count of ray tracing cores, and the only tensor core array in this comparison. Its 35 W TDP makes it the obvious choice for any mobile, battery-powered, or thermally constrained system. The Arc A380E is the better memory-oriented part, with 6 GB of capacity and 45.3% more bandwidth, plus a standardized set of four DisplayPort 2.0 outputs for desktop integration. For a workload that is shader-bound or ray-traced, the RTX 500 Mobile wins decisively. For a workload that is bandwidth-bound, such as high-resolution texture streaming or multi-display output, the Arc A380E holds the advantage. The RTX 500 Mobile also stands out for AI workloads due to its 64 tensor cores, which the Arc A380E cannot match.
