I also don't think a CH V will overclock the same CPU further than a CH IV...
Who says it will, does a CH4 overclock an the very latest AM3 chip further than the best AM2+ board that will also run AM3 chips, unlikely to no.
YOu keep thinking black and white and marketing gimmicks and claims.
Its a standard, not a single board, AM3+ is the spec for the first Bulldozers out, AND chips out 1, maybe 2 years later, will THOSE chips overclock the same on the current AM3 boards as a new AM3+ version.
YOu keep seeming to miss the point, 98-99% of sales are to Dell's, to OEM's, to server builders, etc, etc, these people validate computers by thorough testing for months, often 6-12months for servers. Mobo's can't change on a daily basis, or monthly, the specs, the aims, the targets need to be established years in advance.
Phenom 2 would have a target range of amp drawage, top to bottom, range of voltages, memory voltages, etc, etc, and a mobo standard that fit the spec, top to bottom is created. Bulldozer will have the same design targets, and they make a new mobo standard to fit those targets. If Bulldozer is starting at 100amp's but intended to be at 135amp's in 2 years time, and Phenom 2 chips don't go beyond 105amps, then a new standard needs to be introduced AHEAD of time, WAY ahead of time, that will support the architecture OVER ITS LIFESPAN.
A basic low end AM3 chip worked on AM2+ boards(but not AM2 IIRC), but does a the top end hexcore chips, I honestly don't know, but then that was the same architecture and same process. Thats what you seem to be ignoring, new process, new voltage, amp, leakage, power requirement, on top of a new architecture.
Noise is VERY important, the smaller a node gets, the higher leakage is, the bigger the problem a chip actually has differentiating between 0's and 1's, less noise, cleaner signal, more accurate power is simply required.
Oh, one key thing to remember is how easily AM3+ boards will unlock a cpu, maybe bulldozer's have a chance to unlock, with a new option say Asus come up with to add to the board, but AM3 boards, out long before Bulldozers, can't do it.
I'm still really hoping AMD is going to give us the chance of a 6 core, pretty damn cheap Bulldozer that with a little voltage and a bios option, will unlock to a octo core.
, secondly, overclock the cpu if its a dual core, or unlock cores if possible, or whatever. xfire 6950's aren't even close to being cpu limited by a quad core Phenom 2.
) encoding being done on the on die gpu, Sandybridge-e without that will be way way slower for a lot of encoding jobs.
