At CES 2023, NVIDIA is expected to showcase not only its GeForce RTX 4070 and RTX 4070 Ti desktop graphics cards, but more importantly, the GeForce RTX 40-series laptop GPUs that will keep company in next generation laptops. based on future 13th generation Core «Raptor Lake» processors. NVIDIA seems to be balancing very hard between power management and generational performance gains in this power and heat limited form factor.

The GeForce RTX 40 «Ada» series laptop GPU lineup will be led by the RTX 4090 laptop GPU based on the 4nm «AD103» core (the same one found in the desktop RTX 4080). It will be equipped with 16 GB of memory in a yet unknown core configuration, a GPU boost frequency of up to 2.04 GHz and a typical power consumption of 150 to 175 W, which can reach 200 W thanks to the turbo mode.

Moving down the line, we can see that the RTX 4080 laptop GPU is based on «AD104», the same core found in the desktop RTX 4070 Ti and RTX 4070. The core configurations remain unknown, but given the name, the RTX 4080 laptop GPU is most likely surpasses him. The SKU features 12GB of memory on the chip’s 192-bit memory bus, overclocks to 2.28GHz, and has a power cap similar to the RTX 4090 laptop GPU — from 150W to 175W of typical graphics power, with an additional 25W.

The RTX 4070 is based on the yet-to-be-released 4nm «AD106» core, which is most likely equipped with a 128-bit GDDR6X memory interface with 8GB of memory. This GPU gets a TDP ranging from 115W to 140W, up to 25W. Rounding out the line is the RTX 4060 laptop GPU and the RTX 4050 laptop GPU, both of which are based on 4nm «AD107» cores, which is probably the smallest implementation of «Ada». The first one gets 8 GB of memory and the second one gets 6 GB.
