What is the better processor? i7 v i7?

The 9th gen is slightly faster, but this takes a lot to explain fully.

You cannot know by anything you show. Quad core i7 in 10th generation are mobile processors.

Model number i7-1068G7 is 2.3GHz base and single core turbo to 4.1Ghz, all cores 3.6GHz CPU cores 4 threads 8

benchmark 10,397

The second is a laptop cpu also

Intel Core i7-9750H 

Core i7-9750H @ 2.60GHz benchmark 11,505

rank #41

The i7-9750H is 10.6% faster in most applications. Single core performance of the i7-1068G7 is faster for some applications. Its thermal design is only 28 watts vs 45 watts for i7-9750H. The graphics processor of i7-9750H is Intel UHD 630 rank #410. The i7-1068G7 has Intel Iris Plus Gen 11 rank #241

The graphics processor of the i7-1068G7 is much stronger than the graphics processor of the i7-9750H. In gaming, we expect a separate graphics card.

In some graphics generating applications, the i7-1068G7 would be faster if no extra card is added.

Also, since the i7-9750H is only 10 to 11% faster, other factors of the laptop could be important such as solid state drive and amount and speed of ram.

I would go with the two point six gigahertz processor. Simply because it has a faster base speed.
