I have a inspiron 3647 small desktop computer with a 4th gen 4440s processor can I replace this chip with a 4th gen 4670s processor

It is for free dell put the 4440s in the machine I order and it should of been 4670S as on my invoice don't know what the real difference is but but the 4440s rates it at 2.8 GIB 3.3 turbo and the 4670s slow its a 3.1 GIB 3.6 turbo. I'm just checking to make sure if dell does this upgrade am I not going to have other problems because there is some incompatibility, thanks for your response

There should be zero incompatibility, there both the same processor, just one is a lower power version and the clock speed is lower, but the diffrence between the two wont even really be noticeable.
