"Single Core Score: 1728 (+7.6% over A14)
Multi Core Score: 4695 (+9.3% over A14)"

A14 @ 2.99 GHz
A15 @ 3.22 GHz
= +7.33%

M1 @ 3.2 GHz Single Core: 1721 (iPad Pro https://browser.geekbench.com/v5/cpu/9837998)
+0.4%

M1 @ 3.2 GHz
A15 @ 3.22 GHz
= 0.6%

Conclusion, the difference mainly boils down to an increase in frequency and presumably the bigger cache in multi core score.

Insider info leaked long time ago said that A15 design will be focused on power efficiency. It looks like that . They made it less hungry, probably cooler, better manufacturing process then allowed them to hick frequency and so the performance.  When we see proclaimed battery life improvements we can say that A15 give more juice for the same power. We will see what Anand tech will find up.

It is very likely made on TSMC's newer and improved N5P node, if so the better thermal efficiency is likely free lunch. Meaning Apple didn't put much/any work into it, but is profitting from TSMC's node progress.

TSMC reported that N5P node would only make a 5% increase in performance at isopower, so clearly Apple found anoother place to get some extra performance.

What extra performance are you talking about. As I stated, there is no extra single core performance over A14, except due to higher frequency. M1 is running A14 cores closer to A15 speed and is scoring virtually the same in Single core performance as A15. Likely A15 is running at 3.23GHz within the same thermal envolope as A14 is at 2.99GHz, due to improvements from N5P node.
