The SR-71 is the later version of the A-12. The A12 has better overall performance than the SR-71.
The A12 was slightly faster, Mach 3.3 to Mach 3.2, and could fly slightly higher, 95000 ft. vs. 85000. The A-12 only required one man, the SR-71 two.
But the SR-71, as the successor to the A-12, had a greater refueling range, 3250 miles vs. 2500, and carried a heaver payload, 3500 lbs. vs. 2500.
