From sweclockers, a link to article that talks about a demo AMD ran on Kaveri ES at press conference.
AMD A-Series 'Kaveri' may require a new socket

Upcoming AMD A-Series "Richland" will be no durable processor family without being replaced by Kaveri at the end of the year. This includes a possible transition to socket FM2 +.


Shortly launches new AMD processors with integrated graphics, so-called Accelerated Processing Units (APU). One of these is Richland, replacing today's A-series "Trinity". This variant is not durable. At a press conference in Toronto announces AMD's Director Lisa Su to the sequel Kaveri launched towards the end of the year, just as planned.


AMD A-Series "Kaveri" contains four cores in two modules of the architecture Steamroller and equipped with new graphics, based on an updated version of the Graphics Core Next (GCN) - allegedly with 512 stream processors. Kaveri is also the first HSA-compatible product with HUMA , where both physical and virtual memory shared by the CPU and GPU. In addition, it is also possible to use GDDR5 as system memory. The latter issue in the Playstation 4 and applies in particular circuits tailored to individual customers.
Lisa Su reveals that AMD now has access to functioning circuits architecture Kaveri and demonstrated this with a computer system that runs the game DmC: Devil May Cry. In this connection, also showed the processor for SweClockers emitted, which in appearance looks to fit the socket FM2, which is also confirmed by Lisa Su.
Another of AMD's representatives argue that it is unclear whether Kaveri suited to today's motherboards. Because of the major changes towards Trinity and Richland with new demands on voltage regulation, which probably means that the Kaveri will require an updated socket FM2. This can be named socket FM2 +.
AMD announces that some motherboards can work with an updated BIOS / UEFI, but this may vary depending on model and design, not unlike the situation at the launch of socket AM3 + for FX-series "Bulldozer". However, nothing is yet set in stone.
AMD A-Series "Kaveri" to developers soon

At the same time revealed that Kaveri is in good shape to be delivered to software developers shortly. The official launch will take place towards the end of the year for processors intended for desktop computers, while models for laptops will be delayed until the beginning of 2014.

So the silicon is ready, it's going to software developers soon-a good news. Bad news is that FM2 compatibility is all but confirmed. There is still a chance it might work but AMD is unsure whether mobo makers will release BIOS for their current FM2 boards. The chip is good for Q4 2013 desktop launch and early 2014 for mobile.

I'm not sure we'll see it until next year, but looks promising so far.

The Sweclockers link is down by the way.

It may be that FM2+ is required for GDDR5, which would make sense.

like Am2+ to AM3?

if that's the case, and kaveri can indeed work on FM2 boards with a bios upgrade, this is good news, considering what they did with FM1...


but 512GCN GPU with 128bit DDR3 suffers a lot with the slow memory

That should truly raise the GPU performance. No longer having to perform write back from cpu/gpu frame buffer if I'm understanding correctly.

I think this would be completely dependent of software optimization!?
Game, DX, Driver?

Yeah and Intel demoed Larrabee and we never saw it at all. Phynaz is just up to his usual thread crapping. Ignore him and stick to the tech talk.

well, with P1 AMD demoed a 3GHz chip but released only the 2.3-2.4GHz models for a long time...

The thing is AMD mentioned no clockspeeds (for Kaveri) so that's invalid argument there ;). As a matter of fact they mentioned no performance claims so I still have no idea what he was implying with that post?

I doubt there will be a FM2+ socket. Next step is FM3.

And I hope AMD learned from past mistakes to keep socket compability to satisfy <1% of its users on the expensive of power/performance benefits. They was fast to drop the FM1 socket on the good side.

Likewise, I think Richland is for folks who wanna stay on FM2 & there should be FM3 for Kaveri but anyways lets see how this pans out, I for one will get'em at launch time provided they don't rob us early adopters from my part of the world !

For most people that know "Larrabee", Xeon Phi is practically not one. The graphics aspirations don't carry onto the Xeon Phi.

We now know why Intel never got Larrabee architecture into graphics(or into any product at all!). The Knights Ferry development boards, which was the one that was aimed for graphics has 1TFlop Single Precision FP performance and 150GFlops Double Precision FP performance.

That means the 300W consuming card has graphics horsepower that is only a little better than the Iris Pro in Haswell, while theoretical DP Flops is lower than a single Xeon E5. Sure, Flops aren't everything but when its so low you can only go so far.

Last time I checked, the Phi sat up with AMD and nVidias best cards. And beating AMD badly in Tflop/watt.

Yes, after ditching the GPU aspirations and spending another development cycle on it. This news explains Richland quite well, mobile Kaveri not until next year. Desktop FM2/2+ looks to be going the same route of AM3/3+. Disappointing they didn't work more closely with motherboard makers to build in support but not surprising given AMD's checkered history when it comes to working with supporting vendors.

Even with crippled desktop DDR3, it will blow DDR3 models of the 7750 out of the water. I would buy 2133MHz or faster to deliberately deliver above 7750 performance. Unless GDDR5 doesn't become a problem for casual desktop workflow, I would rather invest into that. The more talk about Kaveri delivering 8 GCN compute units, the more I can't wait to jump on the APU bandwagon (I'll sell my like new HD 5870 to buy a Kaveri A10). By the sounds of it there will be no MMO Kaveri cannot run. With that kind of power, Diablo 3, Dota 2, Skyrim and other games will all play on high presets (16:9). It will be time for me personally to kiss discrete GPU's goodbye, and welcome the extra dollars in my pocket to spend on SSD's or other parts of the system. Overclocking these will be a riot as long as AMD doesn't run into any issues along the way. I don't think they will as its only 28nm and they will be using a better fab process than Intel did for 22nm. I can only imagine the overclock ability and scaling of both the CPU and the iGPU.

I wonder how much GDDR5 kits will cost.

Did they mention if they'll go for 2x64bit or 3x64bit config?

Edit: PS4 is 256bit so this most likely will be 128bit. 256bit for next gen(2015) APU? :whiste:

Highly doubt it.

A 128 bit interface using 900 mhz DDR3 gets around 28GB/sec. 2133 mhz ram gets around 34 gb/sec but has to share that with the cpu. You are not looking at 'blow out of the water'.

5870 to a10 is probably going to be a downgrade.
