Ada Lovelace
Nvidia's consumer GPU architecture, launched October 2022. RTX 4090, 4080, 4070, 4060. TSMC 4N. 2x ray-tracing perf vs Ampere (RTX 30 series). DLSS 3 with frame generation.
4090 ($1599 MSRP): 16384 CUDA cores, 24 GB GDDR6X, ~450W. Mythical Halo card; 2023 priced just under $2000 on real market due to AI deepfake demand rumor. 4060 weak — only 8 GB VRAM, poor value. Power spike issue: 12VHPWR cable melted on several 4090s. Successor: Blackwell consumer (RTX 50 series, 2025). Distinct from Hopper (datacenter Ada): consumer Ada lacks NVLink, comes in AIB cards not SXM.
