Going by the latest news about Bulldozer I have seen posted on the forum, it seems AMD is taking another approach rather than pure performance part with this chip
and is not made to kill Intel`s chips on performance that everyone thought it would be, so it seems Intel will probably be performance king this year coming as well.
What are you talking about, the current rumour mill is that it might not quite match Sandybridge in clock for clock, per core performance per clock, but could be released and overclock to higher clock speeds.
LIkewise its a VASTLY improved IPC speed, its vastly improved performance over phenom per core/per clock/overall and should be the current i7's in clock for clock performance quite easily.
They've gone for a design whereby, hopefully an 8 core Bulldozer should be significantly smaller than an 8 core i7, as with the dual interger cores per fpu design its apparently only added on around 5% die space to add a second core to each module. Meaning price/production wise on the same process(which they won't be to start with but within a couple years glofo should be right on top of Intel when it comes to process release times) it should hold a massive die size advantage.
Its got what should be massively improved interger performance, a lot more FPU performance, fantastic FPU performance when AVX instructions become standard.
Anyway because of the die size increase from current 4 core, to future 8 core designs, they'll basically slip right in at likely marginally higher than current pricing, but the new 4 core versions should be cheaper than current 4 cores, because size wise they'll be closer to dual core than quad core size.
I've been saying for the past year, if you've got any current quad core, unless you do high end constant cpu work for your job where time = money, then theres no significant upgrade to be had for 99% of home use, next year, Sandybridge and Bulldozer are going to be huge advancements.
April production and similar release sounds like utter bull though, CPU's don't take a matter of minutes to pump through a processing line, they get etched, and this and that, for WEEKS, not hours or days.
In GPU terms AMD/Nvidia gpu's take SIX WEEKS from first stage of production to out the other end. I'd say 6 weeks at least really, often more and CPU's take a similar amount of time. Theres so many steps in the process, it takes a very long time.
So if production started on April 1st you wouldn't really expect to have chips finished before mid may/june, and as with most things you tend to wait several weeks so you can launch with a few weeks production ready at least.
IE production in April and a release around the same time, unless a paper launch, is highly unlikely. Also AMD have released server parts before desktop for a long time now, in general, and I wouldn't be surprised if that continued.
I'm fairly sure server parts samples have been "around" for a few months and real production of server versions of Bulldozer could start very soon, potentially even have started already. Bulldozers a MASSIVE change, and on a new process, and a new process for the first time with GloFo split off from AMD, and while GloFo are spending upwards of 20billion expanding, upgrading and building fabs from scratch so they are a tad busy aswell.
Realistically Bulldozer could launch anytime from March to September depending on when they start production.
