AM3's still in favour
CPU-Z highlights that the 970 BE of the same C3 revision as the 125W Phenom II X4 965 BE. No surprises there. Moreover, AMD's processor-comparison chart shows that the only meaningful difference between the two is the clockspeed.The Phenom II X6 1075T looks no different to any AM3 processor, either. We reckon AMD's done a good job in placing six execution cores into a long-in-the-tooth architecture that's currently manufactured on behind-the-curve 45nm technology.
A peek at the stepping and confirmation from AMD's useful chart indicates that, save for frequency, it's pretty much identical to the 1090T. The 1075T has a greater voltage range, perhaps indicating that the chip company isn't as fussy with the underlying silicon as on the 1090T: you may receive a 1075T with an operating voltage of 1.475V or, if you're lucky, of just 1.0V.
Summary
A look at the chips confirms that AMD isn't bringing any new mojo with the release of these two high-end processors. Let's now see how they fit in.
