I read a post recently that was posted a year ago by an AMD processor APU that has eight cores that would be based off the PS4 processor?
Have there been any updates since then?
well the PS4 APU is on the AM1 socket which just came out so they could possibly be making them but they could be under some contract or nda of some sort. the only reason i would see that they are not is because of the heat for it,
I'd like to see them scale up to a 220w TDP APU.

I want to see them release a chipset that uses GDDR5 as system memory with quad-channel support. That would be awesome, but not possible with the current pinout (and likely the size) of the socket FM2+ socket. If they finally ditched the pins and went for contacts, like Intel, then they might be able to make it work on that size of chip. I also like what the author queries, about whether AMD would be considering a bit beefier of an integrated graphics solution on their APU, should they increase the chip and die size to allow them to pin out for quad-channel GDDR5. If they released a chip with 20 GCN cores (1280 stream processors) then the APU would become quite a serious option. The problem is both the heat, which would be severe, and the price, which would go up. I think they need to just stop beating around the bush and create a 2"x2" chip which includes all of the necessary controllers, so that the thing would still fit on a mini-ITX board (with an AIO cooler being practically a requirement, since the APU would likely have a TDP of 140-200W...) But, like, seriously AMD, stop teasing us with these APUs that are almost good enough to buy.
Primarily, AMD needs to sink a bunch of this new console money into transistor development. They need to figure out a way to overcome their current transistor design limitations to reduce the tolerances of their transistors, even if they don't shrink the size any further, as Intel is wont to do. Intel uses rare earth metal oxides, such as Yttrium, as shielding agents to help prevent leakage from the transistors. On top of that, they also developed the first '3D transistor', the tri-gate transistor. AMD needs to go invest some money into the world of physics to see if there is any possible alternative to the transistor technology that Intel is using, and work on bringing that into their lineup. After they've fixed that, they need to revive the Phenom line of processors and stop using this damnable 'module' design of processing cores. It's just shameful. The Phenom II series of processors are more capable, clock-per-clock, than their newer FX replacements. I would bring it back as the Phenom IV, and post-posthumously rename the FX series as the Phenom III.
Incorrect, the processing cores implemented within the PS4 are present on the new Sempron chips on the AM1 platform.
The number of GCN cores is much lower, depressingly so.
since when does AMD care about heat on their CPUs?

An am1 or FM2 board with GDDR5 on it would be kinda cool.....
GDDR5 would suck as system memory... The reason why GDDR5 memory isn't currently used as system memory is because the timings on it are absurd compared to DDR3 or DDR4. There's a lot of different factors that complicate GDDR5 being used as system ram. The memory bit rates don't work like DDR1/2/3/4 do. In GDDR5 they add up and on DDR3 the processor has a 64bit controller so the ram works in 64bit in single channel, in dual channel it adds and goes to 128bit and so forth for higher channel density's. But in GDDR5 the gpu can use multiple 32bit memory chips. So for example, to get the 256bit memory bus on a Gtx 760 it needs 8 memory chips. Then to get 8gb's of dual channel memory you need 2 sticks of 4gb size. Very complicated and I'm not quite sure how it works on Ps4. It may be some work around I'm not aware of or its just some special design thing in the Ps4. No matter how they did it, the cas latency of GDDR5 is way to high to be acceptable for desktop use. Server use, maybe. But for desktop's, the cas is just to high.
I'd like to see them intergrate either quad channel memory controller or have memory slots specifically for the GPU, DDR4 is just around the corner and also either work on their cache latency or MOAR cache like they did on the xbox one chip
as far as transistor design, besides a better composition, they actually need to hand design the transistors, one guy who retired from amd said they have a computer do it which is only about 10% as efficient as a hand designed one so if they do that then they could save enough space for a die shrink, plus the better materials would be helpful too
