Sometimes more means less. The first multi-core central processing units based on Piledriver micro-architecture will be reportedly released next month and will even have sixteen x86 cores. What should be noted is that the chip will be aimed at high-performance servers and will have low clock-speed.

Piledriver micro-architecture that many pinned a lot of hopes on as on a breakthrough for Advanced Micro Devices when it comes to x86 performance has so far failed to impress with the low-power mobile accelerated processing units (APUs) code-named Trinity. Moreover, it will take some time before code-named Vishera chips with Piledriver cores reach desktops as the first high-performance multi-core processors with Piledriver cores to be released will be aimed at servers, which do not exactly require extreme performance demanded by the high-end desktops, reports VR-Zone web-site.

Although Advanced Micro Devices clearly knows how to build energy-efficient microprocessors for mobile computers, in the recent years the company has failed to release high-performance chips for desktops. Apparently, Piledriver micro-architecture will hardly become AMD's "saviour" when it comes to per-core x86 performance. Trinity may offer decent speed for mainstream PCs, but the eight-core and six-core FX-series processors will barely offer much better performance than existing models, which is why AMD is concentrating on multi-core offerings  for servers.

In case Piledriver does not provide truly high per-core performance, then AMD will essentially be two years behind Intel in terms of speed for another year. Therefore, all the hopes will be put on the next-generation AMD cores code-named Steamroller, which are due in late 2013 or even early 2014, according to AMD's roadmaps.

AMD did not comment on the news-story.

Get your facts straight, 28nm is not a processor node that AMD nor Intel are using, 32nm was the node for Bulldozer, 22nm is the node for Steamroller, 28nm is used for their graphics card division. And no, your comment demonstrates that you apparently lack all common knowledge that should be present in anyone commenting on a technology article.

And who will provide 22nm for AMD next year?
May be Intel?
Do you know what's going on in fab business?

According TomsHardware review, Pilledriver is 15% faster than Buldozer, I think to call it "failure" is nonsense...

That was Trinity (Piledriver without the L3 cache), so full fledged Piledriver will be faster

That was a joke of Toms. Don't buy it seriously.

When AMD release 'fixed' steamroller, intel release Haswell and AMD does not improve his 'superiority'.

Mid-mark doesn't mean low performance. A $225 Haswell chip should beat all AMD Piledriver chips just like right now i5-3570K beats all Bulldozers. It's still good to see AMD keep working on improving their CPUs and at least trying to compete, but to call Haswell low- and mid-market is laughable since it'll also add 10-15% IPC on top of the already class leading Sandy Bridge/IVB and still use Intel's advanced 22nm 3D transistors.

If Intel fixes the IVB solder IHS disaster, we may see 5.0ghz+ Haswell overclocks as well.

In this case you contradict your own posting above. Here you state Steamroller would run at lower power than BD. If SR cores would have the same IPC and clock frequency as BD cores, but need less power, this would allow do put more cores into the same TDP and in turn lead to higher parallel performance.

But if you would correlate lower power with lower performance, you could achieve the same with BD already, so there would be no sense in doing this just to have differently called cores.

Where did you get from that SR will have the SAME freq as BD?
My estimate, and you've been knowing quite well that I am 99.9% true in forecasting and many hate me for this, SR will have freq well below 3.0GHz.

Where do you get that SR will have lower frequency? My fact, 83% of statistics are made up on spot, and yours are no different. Apparently, you don't belong on a technology discussion. If you are going to talk about technological events and products, you need to bring actual facts into the picture instead of spreading around your ill-fated misinformed diarrhea all over the place. This might appeal to the fanboy crowds who would do anything to thumb up such a comment, although it really makes these fanboys look very conceitedly embarrassing. You have apparently missed processor design and eletronic nanophysics 101. There is already a decent amount of information leaked onto the web about what they are doing with Piledriver at the moment, what the fixes are. Clock gate mesh technology will reduce the energy required to reach specific frequencies, while many other untold fixes will improve upon other aspects of their design. Do you think a processor manufacturing company would spend a billion USD on twiddling their thumbs? After having released Bulldozer, they already know full well the faults of it's design. When a company knows that their products have faults, they will no doubt spend time to fix these faults. The main problem with IPC in bulldozer was simply an unavoidable caching error that otherwise could have been fixed if they had as much money as Intel does to brute force design. From a processor shrink, you have a much decreased voltage requirement because the closer the components in any device are, the less difference is required in order to pass electricity through it. This causes power consumption to decrease, and therefore what power is saved is used in pushing clocks higher. Therefore, to say something will have less frequency than a product two generations behind is beyond absurd. If you want to continue posting here, it would be a good idea to research your facts before you talk about them in a careless, haphazard manner.

Had you read my post carefully? I stated it in clear way: it's my forecast.
In a year or so, when we see the real product, we'll can estimate its accuracy. Not earlier.

Your comments are hilariously incorrect. Those of us who actually know about what is going on simply have to facepalm at all of your contradictions and misinformation.

Incorrect? Care to provide example?
The last from last January, which, BTW, turned Charlie in mad, was about Radeons might be inferior to NVidia's 6xx. Now everybody knows that is true.

This story makes no sense if it's stating that Trinity laptop chips are a disappointment, because they are not. In fact they are a big performance boost over Llano which was fine for many mainstream users. AMD sold many millions of llanos and will sell five times or more of Trinity.

As far as Piledriver based desktop and server CPUs, these will show the 15% performance improvement that AMD has projected in their slide above. Considering Ivy Bridge was a ~5% boost over Sandy Bridge, AMD is doing just fine with a 15% boost with Vishera and Abu Dhabi and sales will reflect this.

If you recommend something, it'd be good if you'd provide a reference to your recommendation.
Otherwise, your recommendation looks like a fiction of your mind.

AMD may have sold millions of APUs but you have to compare to last quarter and how they are doing relative to Intel:

"AMD's total shipments of heterogeneous GPU/CPUs, i.e., APUs dropped 13.8% in the desktop from Q1, and 6.7% in notebooks."

Their APU sales for this last quarters have dropped!
