NVIDIA T550 Laptop GPU

4 GB GDDR6 · 64-bit · 1,024 cores

An entry-level Turing-based professional GPU for thin and light mobile workstations, introduced in May 2022 as a step up from the T500. It uses the TU117 chip with 1,024 CUDA cores, 4 GB of GDDR6 on a 64-bit interface and certified professional drivers for CAD and visualization software, but has no RT or Tensor cores. Laptop makers set its power limit, so clock speeds and performance vary between systems.
