Worth a read
Looks like they've done quite a bit of fiddling with the Bulldozer cores. I'm wondering how low they managed to get the L2 latency as that was easily one of the bigger issues with Bulldozer. The reduced leakage is a welcome sign as well.
The AMD claims on Bulldozer were the biggest load of horseshit I've ever seen. JF immediately disappeared after its release in order to not live up to the shame. Frankly that was by far AMD's biggest mistake with Bulldozer. By overstating their improvements they built up a lot of hype and then never managed to live up to expectations.
The difference this time around seems to be that the leaked benchmarks and figures point to AMD's claims being on target. Prior to Bulldozer there were leaked figures and signs, numerous delays that pointed to some serious issues. This time around there's been a far more consistent picture painted and the picture looks pretty good for AMD. The real question is the price. They fucked it up bad with Bulldozer and it's only now that BD is dropping in price to where you can make the argument that it makes sense but it's taken an IB release and numerous SB price drops as well and now BD arguably looks even less attractive than it did at launch. Trinity's die size is slightly bigger than Llanos but apparently no yield issues so let's hope Read was serious about beating Intel on price.
