ASUS ROG Astral White GeForce RTX 5080 16GB

This graphics card uses the NVIDIA Blackwell architecture with 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit bus. It is built for enthusiasts who want high frame rates at 4K and beyond. The OC Edition ships with factory overclocking for extra headroom in demanding titles.

PCI Express 5.0 x16 interface limits

The card connects through a PCI Express 5.0 x16 slot, which provides up to 32 GT/s per lane. A motherboard limited to PCI Express 4.0 will halve the theoretical peak bandwidth. The 30 Gbps memory clock also relies on the full 5.0 link to avoid bottlenecks in memory-heavy workloads.

Check motherboard slot and display outputs

Verify that your motherboard has a full-length PCI Express 5.0 x16 slot wired for 16 lanes. Confirm your power supply has the required 12VHPWR connector for this model. The card offers two HDMI 2.1b and three DisplayPort 2.1a outputs for up to four displays at 7680 x 4320 resolution.

Perguntas sobre este artigo

Should I choose the 16 GB GDDR7 version of this ROG Astral RTX 5080?

This model ships with 16 GB of GDDR7 memory on a 256-bit bus running at 30 Gbps, giving you the full memory configuration for the RTX 5080 GPU.

What does the 10752 CUDA core count mean for actual performance?

The 10752 CUDA cores handle shading, compute and ray-tracing workloads on the Blackwell architecture, and they work with DLSS 4.0 to boost frame rates in supported titles.

How does the PCI Express 5.0 x16 interface affect real-world throughput?

The PCIe 5.0 x16 link doubles the lane bandwidth of the previous generation, removing the bus bottleneck for the RTX 5080 when paired with a compatible motherboard.
