Nvidia unveils a broad range of efficient new laptop GPUs, from RTX 4050 to 4090

In addition to un-unlaunching the RTX 4070 Ti GPU for desktops at CES today, Nvidia announced a new range of RTX 4000-series laptop GPUs. Nvidia claims the new GPUs will provide big performance and power efficiency boosts, particularly for the lower-end GPUs that ship in the gaming laptops that most people buy.

The RTX 4000-series laptop GPUs use the same Ada Lovelace architecture as the desktop parts and will come with the same architectural benefits: DLSS 3 support, hardware-accelerated AV1 video encoding, and a more efficient manufacturing process that Nvidia is leaning on to improve power efficiency. (Nvidia didn't specify in its presentation, but presumably it's the same customized 5nm TSMC process used for the desktop Lovelace cards).

We don't have precise specs for any of the GPUs, and most of Nvidia's performance comparisons were pretty abstract. We know there will be 4050-, 4060-, 4070-, 4080-, and (for the first time in laptops) 4090-class GPUs. We also assume that manufacturers can set specific power targets for each GPU, providing better performance in designs that can handle it while tuning for power efficiency in thinner and lighter laptops. We know that each GPU will continue to use "ultra-low voltage" GDDR6 memory rather than GDDR6X, the same as the previous-generation RTX 3000-series laptop GPUs.
