its an odd mishmash of high end on the ram, upper mid range on the gpu, and lower midrange on the cpu ...

using the gddr5 will help hide issues in the cpu but i still feel twoards the end of its life the "eight core" (4 module ) will actually limit what the gpu can do. it will be an interesting switch form this gen where the ram and then gpus were the choke points. and due to the design of the cores, if a game is not programed to take advantage of how the 4 modules operate they could actually slow down the performance below that of a quad core as has been shown on ars in the past.

it will be interesting to see where they take this, at least programming support will be easier... though if they had used intel could have been much easier ....

stupid fake 8 cores .... but then all about arguing what makes a core....


so i guess in summary the ram is a neat choice, the gpu is not as high end as i hopped but not a POS and since its custom may have trick up its sleave
and the cpu leaves a lot to be desired (are we 100% on its clock speed yet)

the clock speed is not really going to be that much of a problem if indeed this is a 3D stacked TSV which im pretty sure it is because the CEO over @ Sony back in jan of 2010 Confirmed it as such, and already Sony is using 3D stacked TSV design already for the PSVita.

the rummored 1.6 would not cut it. go back and look at the IPC of the liniage there yes it has imporved but it needs to be about 15-20% higher clock than comparable intel chips to get close to same leve of output (depeding on work type) even with "8 cores" you will have issues with some games playing at 1.6  . go ahead try out cpu bound games like skrim or civilization, while it will not hurt all games, it will lead to hampering the gpu and limiting the ability to use all resources (throttle a cpu back and play them its not hard to do) and in some cases make them unplayable. 

 

now if its an idle of 1.6 with throttling under load of up to say 4.x  depending on thermals that would work, but could lead to inconsistant game play among consoles 

more practically 1.6 base with a boost to 3.x  designed to keep it form any chance of throttling would work but would agian later in the gen lead to the gpu being hindered 

 

again so this is all not negative props on the gddr5 8 gig did not expect that, and it will be very interesting to see how that ends up being used and how it helps the cpu. I had been expecting at best 4 gig ddr 3 for the cpu and 2-3 gig gddr5 for the gpu , but realistically  4 gig ddr3 for the cpu and 1 gig gddr5  they blew that away and bravo to them

it would be nice to know what gpu family line the custom chip came from  tahiti or pitcarin 

upon reflection of the gpu id like to know the break down of how it was modified/clustered a bit more... it could be more powerful than we think for gaming with some of its gpucompute removed if the right optimizations were made, AMDs 7xxx series chips have left  some gaming on the table to ramp up the gpucompute and costimization could boost performance drastically . could be up to a 7890 performanc  (should have been called a 7930 to avoid chip confusion but both gpu makes seem to hate customers understanding what they are buying )
