The difference you’re seeing is gain bandwidth product. en.m.wikipedia.org/wiki/Gain–bandwidth_product the 741 rolls off at 1MHz and the 5532 rolls off at 10MHz, so it’ll go about a decade higher frequency at about the same performance.
If you want the layout difference, in the 741 datasheet look at section 7.2, and on the ne5532, section 8.2, the schematic is different.
On top of that, the 741 was released in 1968, vs 1979 for the 5532. 10 years is huge.

Thank you, yes I specifically saw a breakdown in my sin wave at ~60 kHz on ua741, and NE5532 got to ~650 kHz before I saw distortion. I thought that was awesome. I will study the layouts as you suggested. Any other advice? Does this also explain the noise floor difference or no?
