Well, I'm certainly late to this party.
The whole incompatibility thing is EXACTLY like the move to dualcore and going from the i925 to the i955x. The chipset needs to be able to handle the logic for the extra CPU on the die, and a hacked i875P certainly isn't going to do it. And, even though the use of the existing e7520 might imply that all you need for the newer server-class e752x series is a BIOS update, there's most likely pin-level differences that need a whole new mobo. I don't know, I haven't looked at the docs, but I don't have much motivation to honestly. This is a dead-end chip.
Thank you. Also, note that the tests were oriented mostly towards the Opteron's already known and proven strengths; there wasn't even one single PS bench in the whole thing, for example. Incidentally, the Opteron's strengths (especially servering) benefit more easily from 4 cores, whereas some of the content creation Xeon stuff probably wouldn't scale as well.
more cores that are slightly slower = Opteron goodness
two cores that are insanely fast = Xeon goodness
^ both for the physical architectures and the applications they're best at

Mr.Guvernment said:i HATE review sites that do this! they will then go on about how intel got their arse handed to them from AMD - like come on!
apples to apples PEOPLE!
