I've excitedly been waiting for the Kaveri launch, and this is it? No real new info, no demos for consumers? Two weeks before it's going to be available to the public, and... nothing except marketing speak? Unfortunately it makes me have second thoughts on preordering.

It won't. I'd focus on the top i3s/low i5s at best for workloads that cannot be offloaded to the GPU. As for workloads accelerated by HSA, that'll be interesting.

you can see clearly where amd has shifted its focus in recent years from raw cpu horsepower to apu's and it just shows you that despite people saying that amd is no longer a cpu performance competitor when it comes to raw cpu power, they are however a heavy competitor in the apu market and that's where the market is now and intel is finally realizing that, because cpu performance alone isn't what it used to be. Now the market has shifted to a all in one type of market where you have good performance from a cpu and gpu at the same time keeping power consumption at a reasonable level.
And better looking case, slim and slick

187% gaming performance. Hmm well that tells me it will be able to do 60fps at 1920x1080 res at reasonable settings. Add AA to the picture and it will drop like a stone. Good for a tv but for gaming on a pc with no aa looks terrible. I suppose that's its intended purpose though so its an ok box to sit under the tv or be in a laptop. As a pc gamer watching this transition as the cpu performance sits stagnant is dam right painful.

No no no no NO NO NO!!!! Did you see what happened to AMD last time they went for "MOOORREEE COOOOAAAARRRSSS!!!111!!!111" which they didn't need? Bulldozer, that's what happened. I'm glad they've finally abandoned that failure and moved back to focusing on CPUs with a sensible number of cores and focusing on IPC, which is where they really lag behind intel.
And I'm vaguely interested in seeing where HSA goes. Vaguely. I'll wait until benchmarks come out before getting too excited.

AFAIK, LibreOffice will support HSA.IIRC, there is also a grapgics program with support for it,...GIMP, Inkscape ? Maybe i'm making confusion.Anyway, i see lots of programs that could benefict with these AMD technologies....There is a graphic showing the speed difference in a search operation....it simply crushes Intel....or any other CPU/APU from AMD.....so, YEAH, in some circunstances, it's like to have 12 CPU cores...

bemused_fredAMD took a gamble on computing moving away from single-threaded workloads, along with shifting floating point work over to GPUs. Obviously, computing hasn't moved away quickly enough. Sure, Bulldozer was very much flawed in terms of starving itself of resources by having a narrow front end (four instructions per core OR module, whereas the new decoupled decoder should theoretically allow for eight), and the caching system was a mess, but some of these issues have been or are being worked out. Steamroller features a larger L1 instruction cache along with the previously mentioned decoupled decoder, but the latter probably sucks down a bit of power which could explain the reduced clock speeds. As far as I can see, power management is on a module level, so individual cores can't be turned off to save power, which must cause the design to use more power than it would had it been a more traditional design, but only when an odd number of cores are in use I suppose.

I can't be the only one who translates this as "they made more Cores than were actually useful in the real world and then fervently wished that all software companies would magically change their coding to help them".

That's true. Adding extra cores to Phenom II was, to me, a stop-gap measure to extend the life of the platform and thus make up for the delay in moving to Bulldozer, and while that worked pretty well, it was a completely different kettle of fish for Bulldozer - weaker cores would usually be offset by having more of them if software could take advantage of it. Intel were happy to keep making big cores which had the ability to take more load if it comes along in the form of HyperThreading, whereas it was essential for AMD to have huge workloads in order to properly make use of the hardware.
A few years back, there was a THG article on how having extra cores helps with system operation, and with respect to running multiple tasks at one time, it showed that a third core (or more) could allow, say, a game to remain somewhat playable if an extra task kicked in. I'd be curious to see this sort of article again with more current processors - details on scaling per core, as well as how those extra cores help when running multiple workloads at the same time. I'm not saying that the FX-6xxx and 8xxx processors will magically do well here, but if they did, at least it wouldn't be so bad.

yeh I see they hype and marketing flying around. Now lets see some real hard facts and real world applications. Good article Don, good info... just waiting on AMD to come out with something make me want to buy. I kinda think AMD isn't going for the performance arena as much as they are really gunning for feature set and complimenting existing technology with all the smart devices.
I hope AMD didn't force them selves into a corner with the Xbox/Sony contracts - It would be cool to see them pumping out APU's in the next couple years with 2 Gigaflops or higher, but I have a feeling they will have the know-how, but won't be able to release them due to the Xbox/Sony contracts...

Awesome. The biggest reason why I stayed away from Piledriver is that I still felt the per core performance still wasn't there and seemed overly reliant on multi core performance. Hopefully with Steamroller, I will be able to scoot by with 4 cores without having to go to Intel. I don't have much uses for 8 cores anyway. The saddled on 7750 will probably hold me over until I can get a decent dGPU and it will be a nice fallback if the dGPU craps out.This along with FM2+ being far better than AM3+ (in my opinion) with it being the only choice with Mini-ITX AMD system makes this a buy from me. Hopefully the benchmarks will back up these infographics.

Maybe 8 core versions when they can go to 22nm or smaller production technology...
You have to remember that in these "cores" there are 2 real cores with two integer parts (and it is called 4 core CPU) so if you want to have 4 real cores, you have to get 8 steamroller cores. But for most people 2 real cores is all they really need! So these are really good CPU to most users. But I hope that we will get "8" core versions in sometime in the future. I want to replase my 4 real core Phenom 2
. There definitely will be those available, the question is when. Most propably we need at least one die shrink until AMD can pack "8" cores and that massive GPU in the one die.

Not even,
Those 8 cores are going to take up a ton of die space with little benefits for the people who would use APUs. They are either going to have to scale back the GPU to a pathetically small size or make a special socket that would accomodate this massive CPU.
Is this thing even remotely interesting for Desktop-PCs that already have a GPU above HD 7750? (price/power wise?)Can this thing work as some kind of upgrade to your more powerfull discrete GPU out of the box (without application optimizing) or is it just for PCs without discrete GPUs?

At this moment... propably not, but if HSA really start moving to programs and programmers, then maybe. The GPU part can do some really heavy work that CPU normally has to do much better and leave the CPU part more resources of doing something else. So there definite is potential in here, but will there be enough support to it, remains to be seeing.
