NVIDIA RTX 5090

The RTX 5090 is the flagship of NVIDIA's 2025 Blackwell desktop generation and, by a wide margin, the largest consumer GPU NVIDIA has released: 21,760 CUDA cores, a massive 32GB of GDDR7, and a 512-bit bus pushing 1,792GB/s of bandwidth over PCIe 5.0. It's built for native 4K at high refresh rates, demanding content-creation workloads, and anyone who simply wants the fastest single GPU available.

All of that comes at a 575W TDP, so it needs a large case, exceptional airflow, and a high-wattage power supply - there is no realistic laptop equivalent at this core count or power draw. For 1080p or 1440p gaming it's significant overkill; its real audience is 4K gaming at the highest settings and GPU-heavy professional work.
