GPU has landed in the form of three new 4000-series graphics cards, and they are beasts. The $1,599 RTX 4090 24GB is a triple-slot 450W monster with 16,384 CUDA cores—50 percent more than the RTX 3090. Next is the $1,199 RTX 4080 16GB with 9,728 CUDA cores, and finally, the RTX 4080 12GB at $899 with 7,680 cores. All three use different versions of the new Ada Lovelace GPU coupled to GDDR6X
