size vs speed

Is there a table that gives the % speed improvment for each processor based routine on the prior processors improvement. For me, if there is only 1% gain using an SSE4 optmized routine vs one from the SSE2 based optomization then adding all the extra code to the app isn't worth it when it has limited space to fit in.

Hello,

There may not be a simple table can show this now. The performance improvements may depends on the functions ( as some function may benefit more from the new CPU instructions), and the actual optimization has been done for the function.

But if you have specific function list, and some system you want to test, The following tool may help you on the test:
