Are newer i5's as fast as older i7's?

I have a Surface 5 with the the older i7 chip (i7-7660U) and I need to replace it with a newer Surface Pro 7 machine. My question is whether I will need the new i7 or if the new i5 is at least as fast as my older i7?

It seems hard to find this comparison on the internet: Older Surface Pro with i7 vs Newer Surface Pro with i5.

Any insights out there??

Since the Pro 7 i5 out-performs the Pro 6 i7 I would say yes :)

Is the Surface Pro 6 relevant in the face of the refreshed Pro 7?

The SP7 CPU is 30% faster.
UserBenchmark: Intel Core i5-1035G4 vs i7-7660U

It's harder to find graphics benchmarks for the i5-1035G4 in direct comparison with the i7-7660U iris plus 640
But Notbookcheck lists both on a 3DMark 11 benchmark:
1280x720 Combined
i5-1035G4 - 2739 +35%
i7-7660U - 2184
1280x720 GPU
i5-1035G4 - 3228 +34%
i7-7660U - 2493
