Intel Arc A380E x2 vs NVIDIA GeForce RTX 5080 SUPER Comparison

Intel Arc A380E x2 and NVIDIA GeForce RTX 5080 SUPER occupy opposite ends of the graphics hardware spectrum, and the recorded data reflects a fundamental divide in compute capacity, memory subsystem, and intended workload. The A380E x2 is a dual-GPU configuration built around Intel's Alchemist architecture, while the RTX 5080 SUPER is a monolithic Blackwell 2.0 part. The benchmark database shows a single recorded 3DMark Steel Nomad DX12 score for the RTX 5080 SUPER, with no corresponding entry for the A380E x2, meaning direct numerical comparison is limited to the NVIDIA part's standing against its nearest rivals. What follows is an analysis based strictly on the specification sheets, architecture details, and the available performance percentile data.

Where Each One Wins

The Intel Arc A380E x2 delivers its advantage in scenarios defined by parallel output and compact physical integration. The card carries 8x mini-DisplayPort 2.0 outputs, a feature set that points toward multi-display signage, digital kiosks, or video wall deployments where a single card must drive numerous independent signals. Its single-slot profile, 265 mm length, and 1x 6-pin power connector allow installation in dense chassis where space and power delivery are constrained. The 130 W TDP and 300 W suggested PSU requirement reinforce this positioning as a low-power, high-output solution for embedded or commercial environments. The Xe-HPG architecture with 8 ray tracing cores and DirectX 12 Ultimate support means it is not bereft of modern rendering features, but its 4.096 TFLOPS FP32 throughput and 186.0 GB/s memory bandwidth cap its ceiling for heavy 3D workloads.

The NVIDIA GeForce RTX 5080 SUPER wins decisively in raw compute and rendering performance. Its 56.28 TFLOPS FP32 rate is an order of magnitude higher than the Intel part, and its 1.02 TB/s memory bandwidth, 24 GB GDDR7 frame buffer, and 256 bit bus provide the data throughput necessary for high-resolution rendering, ray tracing, and AI-adjacent workloads via 336 tensor cores. The 3DMark Steel Nomad DX12 score of 3075 places it in the 19th percentile of all GPUs in the database, a position that indicates it outperforms the vast majority of recorded graphics cards. The nearest rival data shows it is 3.1% ahead of the NVIDIA GeForce 820A and 3.6% ahead of the NVIDIA GeForce GTX 860M, while trailing the NVIDIA Quadro P1000 by 2.8% and the Intel Arc Pro B60 by 3.4% in the same benchmark. The A380E x2 has no recorded benchmark score and no nearest rival entries, so its performance percentile of 50 is derived from specifications rather than direct testing.

Architecture Differences

The two GPUs are built on different architectures from different generations. The Intel Arc A380E x2 uses the DG2-128 chip based on Xe-HPG architecture, belonging to the Alchemist generation (Arc 3). It is fabricated on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9M per mm². The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip based on Blackwell 2.0 architecture from the GeForce 50 generation. It is built on a 5 nm process, also at TSMC, with 45,600 million transistors on a 378 mm² die, for a transistor density of 120.6M per mm². The transistor density difference, 45.9M versus 120.6M per mm², indicates a significantly tighter packing of logic on the NVIDIA die.

Compute resources diverge sharply. The A380E x2 provides 1024 shading units, 64 texture mapping units, and 32 raster output units. The RTX 5080 SUPER provides 10752 shading units, 336 TMUs, and 112 ROPs. Ray tracing hardware scales similarly: 8 RT cores on the Intel part versus 84 RT cores on the NVIDIA part. The NVIDIA GPU also includes 336 tensor cores, while the Intel card lists none. The A380E x2 supports FP16 at 8.192 TFLOPS via a 2:1 ratio, meaning half precision is double the FP32 rate. The RTX 5080 SUPER supports FP16 at 56.28 TFLOPS with a 1:1 ratio, meaning FP16 throughput equals FP32. This architectural choice indicates the NVIDIA part is designed for sustained compute across precision formats without a throughput penalty.

The memory architectures reflect different design goals. The A380E x2 uses 6 GB of GDDR6 on a 96 bit bus, delivering 186.0 GB/s. The RTX 5080 SUPER uses 24 GB of GDDR7 on a 256 bit bus, delivering 1.02 TB/s. Effective memory clock speeds are 15.5 Gbps for the Intel card and 32 Gbps for the NVIDIA card. The NVIDIA part also uses a PCIe 5.0 x16 interface, while the Intel card uses PCIe 4.0 x8. The PCIe 5.0 x16 link provides substantially more host bandwidth, which matters for data-intensive workloads that stream geometry or textures from system memory.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two products. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. The only recorded performance data is the RTX 5080 SUPER's 3DMark Steel Nomad DX12 score of 3075. That score places the GPU at the 19th percentile among all GPUs in the database. The nearest rivals around this score provide context for the NVIDIA part's standing. The NVIDIA Quadro P1000 averaged 3163, which is 2.8% higher than the RTX 5080 SUPER's score. The Intel Arc Pro B60 averaged 3182, 3.4% higher. On the lower side, the NVIDIA GeForce 820A averaged 2983, which is 3.1% below the RTX 5080 SUPER, and the NVIDIA GeForce GTX 860M averaged 2967, 3.6% below.

These deltas indicate that the RTX 5080 SUPER, despite its massive specification sheet, sits in a mid-range performance band according to this particular DirectX 12 workload. The 3DMark Steel Nomad benchmark is a demanding test, and scoring 3075 while being within 3.6% of older or lower-tier parts suggests the database's percentile calculation may weight results from a broad and uneven sample pool. The A380E x2 has no comparable score, so any direct performance comparison between the two cards must rely on the specification deltas rather than measured results. The FP32 throughput difference, 4.096 TFLOPS versus 56.28 TFLOPS, is the most direct indicator of relative compute capability. The texture rate difference, 128.0 GTexel/s versus 879.3 GTexel/s, and pixel rate difference, 64.00 GPixel/s versus 293.1 GPixel/s, reinforce the NVIDIA card's dominance in fill-rate-bound scenes.

The A380E x2's 50th percentile ranking, assigned without a benchmark score, suggests its aggregate capabilities place it at the median of all GPUs in the database. The RTX 5080 SUPER's 19th percentile ranking, based on its actual Steel Nomad run, places it above roughly 81% of recorded GPUs. Neither ranking directly compares the two cards to each other, but the percentile gap implies the NVIDIA part occupies a higher performance tier in the database's overall distribution.

Specification Differences

The two cards differ across nearly every measurable specification. The Intel Arc A380E x2 uses the DG2-128 chip, while the NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip. The process nodes differ: 6 nm for Intel, 5 nm for NVIDIA, both at TSMC. Transistor counts are 7,200 million versus 45,600 million. Die sizes are 157 mm² versus 378 mm². Transistor densities are 45.9M per mm² versus 120.6M per mm². Base clocks are 2000 MHz versus 2295 MHz. Boost clocks are 2000 MHz versus 2617 MHz. The Intel card has a fixed clock for both base and boost, while the NVIDIA card boosts 322 MHz above its base.

Memory configurations differ completely. The A380E x2 has 6 GB GDDR6 on a 96 bit bus with 186.0 GB/s bandwidth. The RTX 5080 SUPER has 24 GB GDDR7 on a 256 bit bus with 1.02 TB/s bandwidth. Effective memory clock is 15.5 Gbps versus 32 Gbps. Shading units number 1024 versus 10752. TMUs number 64 versus 336. ROPs number 32 versus 112. RT cores number 8 versus 84. Tensor cores are absent on the Intel card and number 336 on the NVIDIA card. Pixel rates are 64.00 GPixel/s versus 293.1 GPixel/s. Texture rates are 128.0 GTexel/s versus 879.3 GTexel/s. FP32 performance is 4.096 TFLOPS versus 56.28 TFLOPS. FP16 performance is 8.192 TFLOPS (2:1) versus 56.28 TFLOPS (1:1).

Power and physical specifications also diverge. The Intel card has a 130 W TDP, is single-slot, uses a 1x 6-pin power connector, and suggests a 300 W PSU. The NVIDIA card has a 415 W TDP, is dual-slot, uses a 1x 16-pin power connector, and lists no suggested PSU. The Intel card is 265 mm long, 127 mm tall, and 20 mm wide. The NVIDIA card is 304 mm long, 137 mm tall, and 40 mm wide. The Intel card uses PCIe 4.0 x8, while the NVIDIA card uses PCIe 5.0 x16. Display outputs are 8x mini-DisplayPort 2.0 for Intel versus 1x HDMI 2.1b and 3x DisplayPort 2.1b for NVIDIA. The Intel card is end-of-life and was released on 2024-03-31, with Battlemage listed as its successor. The NVIDIA card is active and has a release date of 2025-12-31. The NVIDIA card has a launch MSRP of 999 USD.

The Verdict

The recorded data supports a clear split by workload. The Intel Arc A380E x2 is a specialized multi-display card. Its 8x mini-DisplayPort 2.0 outputs, single-slot design, 130 W TDP, and 6-pin power requirement make it suitable for installations that prioritize output count and physical footprint over raw rendering power. Its 50th percentile ranking, derived from specifications rather than benchmark scores, indicates it is an average performer overall, but the architecture includes modern features like DirectX 12 Ultimate and 8 ray tracing cores. This card is not designed for high-end gaming or compute-intensive rendering; its 4.096 TFLOPS FP32 and 186.0 GB/s bandwidth are modest figures that align with its commercial display focus.

The NVIDIA GeForce RTX 5080 SUPER is the clear choice for compute and rendering workloads. Its 56.28 TFLOPS FP32, 1.02 TB/s memory bandwidth, 24 GB GDDR7 frame buffer, 84 RT cores, and 336 tensor cores place it in a different performance class entirely. Its 3DMark Steel Nomad DX12 score of 3075, while only narrowly ahead of the GeForce 820A and GTX 860M in the nearest rival data, still positions it at the 19th percentile of all GPUs, meaning it outperforms the majority of the database's recorded hardware. The 415 W TDP and dual-slot form factor reflect the power required to sustain that performance level. For users needing maximum compute throughput, high-resolution frame buffers, or tensor core acceleration, the RTX 5080 SUPER is the only option between these two that the data supports. The A380E x2 remains a niche product for multi-screen output, while the RTX 5080 SUPER is a general-purpose high-performance GPU.
