The 1030 has 384 CUDA cores. I am somewhat surprised by this, but it suggests that I might even be able to experiment with CUDA programming on this low end card.
To my surprise, I learn that it is possible for display and CUDA programming to be done on the same hardware. In other words, you don't need to dedicate an Nvidia card to CUDA development. You can be fooling around with CUDA experiments while the same card is driving your display.
The RTX 3060 has 3584 CUDA cores, along with 28 RT cores and 112 Tensor cores. The RTX 3060 was officially released on February 25, 2021.
