I did some tests today running Superposition.
My results showed that having both CCD's enabled resulted in a much lesser result I ran my tests with one CCD enabled vs both CCS's for all of the caching modes regarding the X3D Cache.. here are the results.
AUTO FREQ CACHE Driver
CCD2 OFF 48100 48129 47998 48282
CCD2 ON 42494 42476 45394 43005
I am assuming here that AUTO lets the BIOS sort out what to run where, FREQ will run on the CCD parts with the highest frequency, CACHE will try and run everything in CACHE first and Driver will let AMDs Cache drivers decide, either way it seems horrific to me that in order to get the best performance when gaming you have to turn off the 2nd CCD and manually adjust the BIOS in order to get top performance and lets not kid ourselves here close to 6000 points in this test is not a minor difference you are talking 12.5% which is as much as a generation of CPU in speed that is just left sitting there.
