In general, does a 64-bit CPU just have two 64 bit inputs and one 128 bit output (so 276 pins I/O pins total)? Does that mean a CPU usually only does one calculation between two 64-bit inputs every clock cycle?

 

Current generation 64 bit processors have over a thousand pins.

 

Over a thousand data I/O pins? I'm just looking for the general premise of a CPU. About how many calculations does the average CPU do each clock cycle?

 

No. CPUs have data sheets. That shows and explains how the CPU works.

 

What does a general cpu mean to you?

 

Hello,

What CPU are you looking for?
The Intel I7 has a LGA2011 socket:

There will be multiple pins for powers and ground.

I'm just looking for the general premise of a CPU.

Generally, a 64 bit processor would have 64 bit wide I/O.

There is no general answer; it depends on architecture.

LGA3647 socket has 3,647 pins! And that is not "new".

 

This is my 64 bit general cpu. I use it on my desktop.

It is several years old and I believe, out of production now.

https://www.newegg.com/Product/Product.aspx?Item=N82E16819116901

It has 1151 pins.

Here is the first volume of the datasheet.

There is also no requirement for operations inside the CPU to use any external input or output. Those external accesses only occur when the required data is not already in an internal cache memory, or needs to be written to external memory.

 

And are we considering multi-core CPUs? Those can be performing multiple operations at the same time.
