Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Intel Arc G3 Extreme and the NVIDIA GeForce RTX 5080. The Arc G3 Extreme has zero benchmark scores recorded, and the winsA and winsB counters are both zero. The RTX 5080's individual benchmark results are all recorded, however. In 3DMark Steel Nomad DX12, it scores 8,637. In Geekbench OpenCL, it scores 235,901. In Geekbench Vulkan, it scores 255,450. PassMark results show 208 for DirectX 10, 324 for DirectX 11, 151 for DirectX 12, 389 for DirectX 9, 1,415 for G2D, 36,565 for G3D, and 21,789 for GPU compute. These figures place the RTX 5080 at the 87th percentile. The Arc G3 Extreme has no equivalent recorded data, so direct numerical comparison is impossible. The RTX 5080's nearest rival data provides context: its average score of 56,083 is 0.6% above the AMD Radeon 8060S, 0.7% above the AMD Radeon RX 6750 GRE 12 GB, 2.3% above the AMD Radeon Pro W5700X, and 2.2% below the AMD Radeon RX 9070 GRE.

Where Each One Wins

The RTX 5080 wins in every measurable benchmark category because it is the only part with recorded scores. Its 56.28 TFLOPS FP32 throughput, 293.1 GPixel/s pixel rate, and 879.3 GTexel/s texture rate indicate a design built for high-resolution, high-frame-rate rendering. The 16 GB GDDR7 memory with 960.0 GB/s bandwidth supports large textures and heavy compute workloads. The 336 tensor cores and 84 ray tracing cores provide dedicated acceleration for AI and ray tracing tasks. The RTX 5080's 87th percentile ranking confirms its position among the top GPUs in the database.

The Arc G3 Extreme wins in power efficiency and integration. Its 80 W TDP versus the RTX 5080's 360 W TDP means it consumes a fraction of the power. Its 3 nm process node is more advanced than the RTX 5080's 5 nm node. The integrated design with no power connectors and IGP bus interface makes it suitable for portable devices where space and power are limited. Its 15.36 TFLOPS FP16 throughput with a 2:1 ratio indicates some compute capability, but the 50th percentile ranking and absence of benchmark scores show it is not positioned for high-end rendering. The data suggests the RTX 5080 is for desktop systems with dedicated power delivery and cooling, while the Arc G3 Extreme is for mobile or compact platforms where the RTX 5080's dual-slot, 304 mm length, and 750 W PSU requirement would be impractical.
