Intel Arc A380E vs NVIDIA GeForce RTX 5080 Comparison

The Verdict

The database places the NVIDIA GeForce RTX 5080 in a completely different competitive tier from the Intel Arc A380E. The RTX 5080 sits at the 87th percentile among all GPUs, while the Arc A380E sits at the 50th percentile. The RTX 5080 is the only one of the two with recorded benchmark scores, and its average benchmark score of 56,083 dwarfs the Arc A380E's unrecorded baseline. The Arc A380E is an end-of-life product from the Alchemist generation, while the RTX 5080 is an active GeForce 50-series part.

For users seeking maximum rendering performance, the RTX 5080 is the clear choice. Its FP32 throughput of 56.28 TFLOPS is roughly 13.7 times the Arc A380E's 4.096 TFLOPS. The RTX 5080 also delivers 879.3 GTexel/s of texture fill rate versus 128.0 GTexel/s on the Intel part, and 293.1 GPixel/s versus 64.00 GPixel/s. The RTX 5080's nearest rivals in the database, the AMD Radeon 8060S and AMD Radeon RX 6750 GRE 12 GB, sit within 0.7 percent of its average score, indicating the RTX 5080 is competitive within its immediate peer group.

The Arc A380E serves a different purpose entirely. Its 75 W TDP requires no power connectors and only a 250 W suggested PSU. The RTX 5080 draws 360 W and needs a 16-pin connector with a 750 W suggested PSU. The Arc A380E is also shorter at 254 mm versus 304 mm, and thinner at 20 mm versus 40 mm. For constrained systems where power delivery and physical space are the limiting factors, the Arc A380E is the only viable option in this pairing.

Where Each One Wins

The RTX 5080 wins in every measurable performance category. PassMark G3D score of 36,565 and PassMark GPU Compute score of 21,789 demonstrate strong general rendering and compute capability. Geekbench OpenCL score of 235,901 and Vulkan score of 255,450 show cross-API proficiency. The 3DMark Steel Nomad DX12 score of 8,637 indicates strong modern DirectX 12 performance. The RTX 5080 also has a larger memory footprint at 16 GB of GDDR7 versus 6 GB of GDDR6, a 256-bit bus versus 96-bit, and bandwidth of 960.0 GB/s versus 186.0 GB/s.

The Arc A380E wins in power efficiency and installation flexibility. Its 75 W TDP is one-fifth of the RTX 5080's 360 W. It uses no external power connectors, occupies a single slot, and measures 254 mm long, 127 mm tall, and 20 mm wide. The RTX 5080 is dual-slot, uses a 16-pin connector, and is larger in every dimension. The Arc A380E also provides four DisplayPort 2.0 outputs, while the RTX 5080 offers one HDMI 2.1b and three DisplayPort 2.1b outputs.

The RTX 5080's transistor count of 45,600 million on a 378 mm² die gives it a density of 120.6 million transistors per mm². The Arc A380E packs 7,200 million transistors into 157 mm², a density of 45.9 million per mm². The RTX 5080 also has far more execution resources: 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores versus the Arc A380E's 1,024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores.

Architecture Differences

The two GPUs come from different architectural families. The Arc A380E uses Intel's Xe-HPG architecture on the DG2-128 chip, part of the Alchemist generation. It is built on a 6 nm process at TSMC. The RTX 5080 uses NVIDIA's Blackwell 2.0 architecture on the GB203 chip, part of the GeForce 50 generation, fabricated on a 5 nm process at TSMC.

The compute capability differs fundamentally. The Arc A380E delivers 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16 with a 2:1 ratio. The RTX 5080 delivers 56.28 TFLOPS for both FP32 and FP16 at a 1:1 ratio. This means the RTX 5080 does not halve its throughput when switching to FP16, while the Arc A380E doubles its rate with reduced precision.

Memory architecture also diverges. The Arc A380E uses 6 GB of GDDR6 with a 96-bit bus and 186.0 GB/s bandwidth, running at 1937 MHz with 15.5 Gbps effective speed. The RTX 5080 uses 16 GB of GDDR7 with a 256-bit bus and 960.0 GB/s bandwidth, running at 1875 MHz with 30 Gbps effective speed. The RTX 5080's memory clock is lower in MHz, but the higher effective data rate and wider bus produce more than five times the bandwidth.

The RTX 5080 includes 336 tensor cores, which the Arc A380E lacks entirely. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 uses PCIe 5.0 x16, while the Arc A380E uses PCIe 4.0 x8. The RTX 5080's 84 RT cores versus the Arc A380E's 8 RT cores indicate a substantial difference in ray tracing throughput.

Clock behavior is also different. The Arc A380E has a flat clock profile with base and boost both at 2000 MHz. The RTX 5080 has a base clock of 2295 MHz and a boost clock of 2617 MHz. The RTX 5080's boost clock is 30.85 percent higher than its base, while the Arc A380E shows no boost headroom in the recorded data.
