There are new results from testing the latest current generation of CPUs using the latest version of DAWbench. You can read up on it in these places:
(the second link doesn’t work for me).
For those who don’t know how the test results differ and don’t want to read up on it the short version is that the DSP test focuses on running plugins whereas the “VI” test focuses on the number of voices played back when using virtual instruments. There’s an argument to be made then that if you’re mostly mixing and not playing back instruments in realtime the DSP test might be a better indicator of what performance you’ll get, whereas if you play virtual instruments in realtime the “VI” test is more appropriate.
Please note: this test is performed using Reaper which if I understand correctly scales much better across CPU cores than Cubase/Nuendo does. So the test shows the relative performance between the CPUs, not an absolute number that you can achieve in Cubase/Nuendo.
