i7 3770 vs 4770 is math coprocessor the same? need info for Software V&V

looking for literature that confirms the math coprocessor used in the i7 4770 is equal to that in the i7 3770. Thanks.

Stidhamjason, what do you mean with math coprocessor?

The CPU micro architecture now contains ALU's (Arithmetic Logic Units) and FPU's (Floating Point Units) that do the job of a traditional math coprocessor.

There have been improvements in the ALU/FPU instructions with Haswell processors.

Please check the following article for more information about these changes: http://www.anandtech.com/show/6355/intels-haswell-architecture/8 http://www.anandtech.com/show/6355/intels-haswell-architecture/8
