    Stripped-down PS4 SoC... sounds to me like the embedded Kaveri w/ GDDR5...



    I wouldn't be surprised if 28nm Steamroller clocks at 5GHz out of the factory, considering Piledriver refresh (that's still 32nm) will prolly hit 4,5GHz or more... Still, I'd rather they clock it lower and fit in a lower TDP envelope and/or make them in 5M/10C or 6M/12C versions as well.


    Also, why hasn't anyone posted about the desktop Richland moving forward to the 12th of this month? Or the specifications of the normal power mobile parts, or the fact that mobile flagship will suport DDR3-1866.

    Sorry, I just happen to be very up-to-date with AMD APUs at the moment. :p
    And it's kinda frustrating seeing all these crappy news articles about humdrum TITAN brand launches or misc hardware that almost no one is interested it, but nothing on Richland, which is so close to launch.

    You indicated arm was irelivant I was pointing out x86 is largely unimportant now and all these processors are made in the same way's so clock speeds dont vary that much on diff npdes and processes , the rich land apu at 2ghz is a lower bin obv but thats not to say they couldn't have been made quicker, Amd have a lot of sku's lingering in the lower price sector and have to be carefull not to diminish old stock saleability .
    Ps4 will be top bin richland all 8 cores and features working and 2.6ghz it Will be.
    The more I think about it though I too wouldn't be surprised by higher clocks. Efin phone

    Why would you bee surprised by clocks higher than 2.6 GHz. Both current generation offerings from Microsoft and Sony are clocked at 3.2 GHz. While more cores will be a great boon since they can better utilize them, raw clock speed can be very helpful in single threaded applications such as Blu-ray playback, web browsing, system UI, their audio cloud player thingy, etc.

    I personall don't see the cores being less than 3.6 GHz with Turbo up to 4.0 GHz easy.

    PS4 is not Richland. Richland does not have Jaguar cores. Jaguar is an updated Bobcat core, not Bulldozer.

    AMD has already stated what max clocks will be for a 4 core Jaguar with a 25w TDP. If high clocks with low TDP was possible, they would have already done it. PS3 is a Cell design which is totally different from the PS4 AMD design. When you drop a process node, with the same overall design, you either gain higher clocks with the same TDP or lower TDP with the same clocks. I don't know how much of a drop it is going from 40nm to 28nm, but if AMD is saying a 10% clock boost with a slight increase in TDP, I don't see how anyone can come to the conclusion that 3Ghz+ is easy. If it was, then they would have done it. It's not like the TDP of the APU is going to be like that of a desktop either since there are power limits to what a console system can pull from the wall.

    Sos kabini I miswaffled. Put kabini In and my statement stands top bin kabini is ps4 and one t two cores could easy do 3ghz in tdp with scaled p states

    (ignoring core count and IPC gains) E2-2000 1,75GHz @ 18W TDP -> +10% clock = 1,925Ghz @ 18W+ -> 25W ~= 2GHz+ final clocks, for the X4 5110 (25W TDP) flagship. Refreshes will probably go something like 10% beyond that as well (like E-450 to E2-1800 to E2-2000).
     
    mastrdrver says thanks.
