NVIDIA GeForce RTX 3090 Ti

$1000$1999 MSRP

The NVIDIA GeForce RTX 3090 Ti pushed the Ampere architecture to its limits with 24GB of GDDR6X at higher bandwidth than the standard 3090. On the used market, it offers slightly faster AI inference than the 3090 at a modest price premium. The 450W TDP is aggressive, requiring a robust PSU and good airflow. A solid used-market AI pick for those who want the fastest 24GB Ampere option.

VerdictFaster than the 3090 but much hungrier — worth the premium if power isn't a concern.
