HOW TO CHOOSE
RTX 4000 Ada vs RTX A4000
The generational step: 20 GB versus 16 GB, Ada tensor cores with FP8 versus Ampere, and 130 W versus 140 W. The Ada card is faster, roomier, and cheaper to run - the A4000 only makes sense at a deep discount.
Workload fit
RTX 4000 Ada: budget professional inference, cad, rendering, and visualization, fine-tuning. RTX A4000: dev and small inference, graphics.
