Two different VM CPUs

Do you guys see any issues having a production VM running on 4x more powerful vCPU than the standby?  Would it matter much?

Primary production VM CPU:   Intel(R) Xeon(R) CPU           X5675  @ 3.07GHz

Clone standby VM CPU: Intel(R) Xeon(R) CPU E7- 2870  @ 2.40GHz

Just a decrease in performance for the most part if the standby becomes active.  In all honesty VM's can be pretty light on the CPU in my opinion

Main thing to watch for is just compatibility between the two

If you are talking about regular HA you should be fine but if you bring DRS you might have an issue. You may need to have a EVC cluster.

No HA or DRS.  Just a simple warm standby server.  If the primary tanks (OS corruption, application) I will need to spin up a standby with least amount of changes for the application.

How are these two CPU compared?  Is E7-2870 low-end CPU?

I could not find anything on this one.
E7- 2870

There is a pretty big difference there. If you are using  only a small percentage of this CPU E7-2870 I would say you would be fine but if you are taxing this CPU pretty hard I think you may have an issue.

you'll notice a big different between the 2...6 cores vs 10; larger memory supported; more than double the cache
