Is this how CPU performance comparisons work?

Now, I am nearly 100% certain what I am about to say is completely incorrect, but I have no other way to determine it. Can someone please correct my logic here?

The passmark benchmark for each CPU is:
CPU1: 6600k @ 3.5 Ghz benchmark score - 8056
CPU2: 9600k @ 3.6 Ghz benchmark score - 13521

Now, if there is a linear relationship between clock speed and performance....
If my overclock on my 6600k is 4.6 Ghz, then the effective benchmark is 8056 * 4.6/3.5 = 10587
If I expect to overclock my 9600k to be 5 Ghz then the effective benchmark would be 13521 * 5/3.7 = 18272

Based on these numbers, I could estimate a 72.5% performance gain when switching from my 6600k @ 4.6 Ghz to a 9600k @ 5 Ghz in tasks that utilize all the cores.

Edit: Clarity.
Edit2: I went ahead and upgraded my CPU from the 6600k to the 9600k. I am getting about 72.5% more frames in previously CPU bottle-necked games like Destiny. Also, CPU based tasks such as video rendering feel about twice as fast as well, I have no exact data on this.

I had a feeling this would be the case. Would this be a close enough for a decent estimate or would it not even be close?

Ah, my thread was not clear, I will update it. I am attempting to determine the performance boost from upgrading from my 6600k @ 4.6 Ghz to a 9600k @ 5 Ghz.

So I went ahead and upgraded and with a 5Ghz overclock I get around 72% more fps in previously CPU bottle-necked games as well, go figure.

Will totally depends on the software. The 9600k has more cores, so if the program is highly threaded then youll get the biggest boost by the ability to use more cores.

The IPC and clock speed increase will be less dramatic.
