Intel Arc A380E x2 vs NVIDIA GeForce RTX 5080 Comparison

The Verdict

The recorded data positions the NVIDIA GeForce RTX 5080 as the dominant performer in this comparison, with an average benchmark score of 56,083 and a percentile rank of 87 among all GPUs. The Intel Arc A380E x2, by contrast, holds a 50th percentile ranking and carries no recorded benchmark scores in the database, meaning its measurable performance cannot be directly quantified from the available facts. For any workload requiring raw computational throughput, the RTX 5080 is the only option with verified results.

The Intel Arc A380E x2 is an end-of-life product released in March 2024, built on the Xe-HPG architecture with the DG2-128 chip. The RTX 5080 is an active product from January 2025, using the Blackwell 2.0 architecture with the GB203 chip. The data shows the RTX 5080 delivers 13.7 times the FP32 throughput (56.28 TFLOPS versus 4.096 TFLOPS), 5.2 times the memory bandwidth (960.0 GB/s versus 186.0 GB/s), and over 10 times the shading units (10,752 versus 1,024). These are not marginal differences; they represent entirely different performance classes.

Users who require verified benchmark results, modern API support with tensor cores, and a 16 GB GDDR7 memory buffer should select the RTX 5080. The Intel card, with its 6 GB GDDR6 memory, 96-bit bus, and 8 RT cores, targets a fundamentally different workload profile, likely embedded or multi-display deployments given its 8x mini-DisplayPort 2.0 outputs. The Arc A380E x2 has no launch MSRP recorded, while the RTX 5080 carries a launch MSRP of 999 USD.

Architecture Differences

The two GPUs share the same API feature set: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Beyond that commonality, the architectures diverge substantially.

The Intel Arc A380E x2 uses the DG2-128 chip on TSMC's 6 nm process, integrating 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. Its Xe-HPG architecture belongs to the Alchemist generation (Arc 3), with a predecessor of Xe Graphics and successor of Battlemage. The RTX 5080 uses the GB203 chip on TSMC's 5 nm process, packing 45,600 million transistors into 378 mm², for a density of 120.6 million per square millimeter. That is 6.3 times the transistor count and 2.6 times the die area of the Intel part, with a 2.6 times higher transistor density.

Compute resources differ by an order of magnitude. The Intel GPU provides 1,024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores, with no tensor cores listed. The RTX 5080 provides 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The FP16 ratio also differs: Intel lists 8.192 TFLOPS FP16 via a 2:1 ratio, while NVIDIA lists 56.28 TFLOPS FP16 at a 1:1 ratio, meaning the RTX 5080 does not rely on rate-halving for half-precision work.

Memory architecture is another major split. The Arc A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The RTX 5080 uses 16 GB of GDDR7 on a 256-bit bus, delivering 960.0 GB/s. The RTX 5080's memory clock runs at 1875 MHz with 30 Gbps effective, while the Intel card runs at 1937 MHz with 15.5 Gbps effective. The bus width difference, 256 bits versus 96 bits, drives the bandwidth gap.

Clocks and power draw also separate the two. The Intel card runs at a flat 2000 MHz for both base and boost, with a 130 W TDP, single-slot cooler, and a single 6-pin power connector. The RTX 5080 boosts to 2617 MHz from a 2295 MHz base, with a 360 W TDP, dual-slot cooler, and a 16-pin power connector. Suggested PSU ratings follow: 300 W for Intel, 750 W for NVIDIA. The RTX 5080 uses PCIe 5.0 x16, while the Intel card uses PCIe 4.0 x8.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two products, and the Intel Arc A380E x2 has an empty benchmark array. All quantitative comparison must rely on the RTX 5080's recorded scores and the architectural specifications of both parts.

The RTX 5080's recorded results cover multiple test families. In 3DMark Steel Nomad DX12, it scores 8,637. Geekbench results show 235,901 in OpenCL and 255,450 in Vulkan. Passmark results include 36,565 in G3D, 21,789 in GPU Compute, 1,415 in G2D, 389 in DirectX 9, 324 in DirectX 11, 208 in DirectX 10, and 151 in DirectX 12.

Because the Intel card has no recorded scores, the architectural deltas serve as the only comparison metric. The FP32 gap is the most decisive: 56.28 TFLOPS versus 4.096 TFLOPS, a 13.7 times advantage for NVIDIA. Texture rate shows 879.3 GTexel/s versus 128.0 GTexel/s, a 6.9 times gap. Pixel rate shows 293.1 GPixel/s versus 64.00 GPixel/s, a 4.6 times gap. The RTX 5080's memory bandwidth is 5.2 times higher (960.0 GB/s versus 186.0 GB/s), and its ROP count is 3.5 times higher (112 versus 32).

The nearest rivals for the RTX 5080 provide context for its standing within the broader market. The AMD Radeon 8060S averages 55,757, which is 0.6% below the RTX 5080's 56,083. The AMD Radeon RX 6750 GRE 12 GB averages 55,698, 0.7% lower. The AMD Radeon Pro W5700X averages 54,828, 2.3% lower. The AMD Radeon RX 9070 GRE averages 57,367, which is 2.2% higher than the RTX 5080. These deltas show the RTX 5080 sits in a tightly contested band, with the RX 9070 GRE as the only listed rival ahead of it.

Where Each One Wins

The NVIDIA GeForce RTX 5080 wins across every measurable compute dimension in the database. Its 56.28 TFLOPS FP32 and FP16 throughput, 879.3 GTexel/s texture rate, and 293.1 GPixel/s pixel rate place it in a different performance tier than the Intel Arc A380E x2. The 84 RT cores and 336 tensor cores give it dedicated hardware for ray tracing and AI workloads, features the Intel card lacks entirely. The 16 GB GDDR7 frame buffer with 960.0 GB/s bandwidth supports high-resolution textures and large datasets, while the 256-bit bus sustains that bandwidth under load.

The RTX 5080's recorded benchmark scores confirm its standing. Its 87th percentile rank among all GPUs, alongside an average score of 56,083, places it slightly above the AMD Radeon 8060S and RX 6750 GRE 12 GB, and slightly below the AMD Radeon RX 9070 GRE. The 3DMark Steel Nomad DX12 score of 8,637 and Geekbench Vulkan score of 255,450 indicate strong DirectX 12 and Vulkan performance, while the Passmark G3D score of 36,565 and GPU Compute score of 21,789 reinforce the compute-oriented profile.

The Intel Arc A380E x2's advantages are structural rather than performance-based. Its 6 nm process, while older than the RTX 5080's 5 nm node, still offers a complete DirectX 12 Ultimate feature set. The 6 GB GDDR6 memory and 96-bit bus are modest, but the card's 130 W TDP and single-slot design with 8x mini-DisplayPort 2.0 outputs suggest a niche for multi-display configurations or compact embedded systems. The 2000 MHz flat clock profile, both base and boost, indicates a fixed-frequency design suited to consistent operation rather than burst performance. Its 50th percentile rank places it at the midpoint of all GPUs, though with no recorded benchmarks, that rank cannot be validated against specific tests.

The physical dimensions reinforce the positioning. The Intel card measures 265 mm in length, 127 mm in height, and 20 mm in width, a single-slot form factor. The RTX 5080 measures 304 mm in length, 137 mm in height, and 40 mm in width, a dual-slot design. The Intel card's smaller footprint and lower power draw make it suitable for space-constrained builds, while the RTX 5080 demands more chassis and PSU headroom.

For users prioritizing verified performance, the RTX 5080 is the clear choice, with the only listed rival ahead of it being the AMD Radeon RX 9070 GRE at 2.2% higher average score. For users prioritizing compact multi-display output with low power draw, the Arc A380E x2 offers a specific hardware profile, but the database contains no benchmark evidence of its performance capabilities.
