The folks at PC Watch Japan made some diagrams of the PS4 architecture. Its more like a simplified overview of the PS4 from what is known.

Fantastic. It's nice to get visuals.

Except for the fact that the advantage the 360 enjoyed was the fact that it had unified ram which allowed assets to take great allotment of space than the PS3 could provide without a penalty.

Thanks for finding this. Helps me figure out things a lot better. Interesting info about the CPU clock speed too. I'm guessing that's still in flux since we haven't heard anything on that front yet. I was originally thinking they were targeting matched clocks but it sounds like that's completely unnecessary now and it seems like the GPU is set in stone.
The featureset of the GPU sounds super impressive.

They should increase the cpu clock to 2 ghz and gpu core speed to 1 ghZ ^-^

How much performance gain would this lead to? 20%?
In a perfect world...
If they were going to do matched clocks the highest I could see is 1.8/900 but they've been pretty open about 800MHz on the GPU since February so I doubt that'll happen. No confirmation on the CPU clock speed leads me to believe that it'll be more than 1.6 and they won't be going for matched clocks.
25%
GPU would wind up being around 2.3Tflops

Sounds worthwhile
In one of those it says GCN2.Does that mean anything good?
Oh snap. I guess some of the tweaks to the PS4 GPU are really GCN2 tweaks and not just PS4 customizations. Basically it just means more efficiency.
It would also add a ton of heat and a lot more power consumption.
Likely means GCN+

Sony should make a bigger box, add another fan...

Said it before, will say it again: This guy sounds like the best thing to happen to Sony in a long time. I generally agree with his view, but maybe that little puzzle that developers might have to solve isn't as complex as he implies it to be. Coming from 360 development, with the 360's EDRAM, that puzzle is most likely already solved by devs. So it requires a tad bit more care, but I don't foresee this being incredible difficult for devs to do.
Also, Microsoft has historically been pretty good at giving developers the tools and resources they need to get the most of their consoles. They might not have to solve a puzzle if Microsoft already does it for them.

Yes, Microsoft consoles have always been easy to develop for and I am sure Durango will continue this legacy....
We haven't seen an easy to develop for Sony console since the PSOne, so it is big news for the PS4.
I don't know what it is and I don't know why, but I just get a vibe from the PS4 that it will be a return to the PS2 glory years......at least it will be for gamers....

16 ram chips?
Hmm, PS4 has the potential go be larger than the PS3 was at launch...

They are in clamshell mode so take up about the same board spaces as 8.

I get that same sense, too, but they aren't facing the same weakened Xbox, so it'll be interesting to see what consumers do. I technically don't count, since I'm getting all the new consoles.

Well, they don't have to worry about Nintendo this time like they did with the PS3. But, Microsoft is the juggernaut this time. When the Xbox came out, Microsoft didn't have a good handle on how the industry worked. The system was powerful, but they didn't secure the extensive partnerships that Sony did.

I still have faith the Wii-U will produce some incredible games, but I do feel they are in a bad position.
Thanks for posting the new set of screens, danhese007. I do have two queries pertaining to information on the "overview (estimate)" image:
- Why does it say "32 or 16 ROPs"? I thought 32 was pretty much a given especially when cutting it to 16 effectively halves the performance from 25.6Gpixels to 12.8Gpixels/sec, the latter being a less than 3 times increase over RSX's 4.4Gpixels/sec.
- What does 5.5GT/sec for the GDDR5 RAM mean?

I want to know this too. I thought it was confirmed to be 32 ROPs?

Memory transfer rate. Here a slide from the same site for example:

Ah, I realise now that they are using it as a substitute for the memory clock speed, i.e. 5.5 GHz.

I really hope Sony aren't vacillating with the ROPs stuff at this time. I wish there was some sort of confirmation via EDGE/Eurogamer.
Indeed (thanks) and each transfer is tied one cycle.
Well to be frank from the look of things MS is not going to face a hard to code, late and over expensive PS3 like console either.
I never saw the original Xbox as a weak console, quite the contrary actually, it was a great console IMO, but when it launched the PS2 already had the whole market on lockdown. That's why MS had no choice but to kill it early to get the 360 out of the gates first, and that worked wonders for then.
Seems like this time Sony will not only launch first or close to the next box, but they are making sure to avoid mistakes of the past.

I can only understand talk like this when someone applies it to real-world gaming use. So... could someone do that?
hmmm 1.8 ghz +
That would be a nice surprise.
Love to hear more about PSSL. That is the "coding to the metal"
They did a great job on that diagrams.

I think it was an error on their part
Yeah its a shame
AMD have quite a few overclocked options with their GPUs, including 'GHz editions'. So they seem fairly flexible on that front (probably binned so its a cost thing). Wonder what the difference would be heatwise?
Isn't it just [FORUM RUMORS] or did he leak anything that was confirmed by a third party like when VGLeaks leaked stuff and Kotaku had the same things, as did EDGE?

So the cpu can read the gpu cache and vice versa?
So?
4mb lvl2 cache for cpu
512kb lvl2 cache for gpu
He said something about durango having a IBM cpu if im not mistaken.

One thing I still don't really understand is the change from 4 core CPU with higher clocks to 8 core with low clocks. Isn't this going against their new philosophy of making development as easy as they possibly can? Less cores is easier for devs AFAIK. The only reason for the change given their new goals I can think of is to make it as identical to the Xbox as possible just to make sure ports will not suffer? Or maybe they just got it at much better price for them?
Back when rumours first emerged about the change, it was said that Steamroller (the fatter, higher power core that would have come in a group of 4) simply wouldn't be ready in time for launch, so they had to switch to Jaguar.
Maybe one of the reasons was also that they need/want to reserve 1 core for the system?
If they would have reserved one of the 4 steamroller-cores, the loss of power for games would be higher than now.
heat issues and yelds.
Going for higher clocks = lower yelds and more costly cooling = increased price
Which chart? The one pertaining to GHz just says "1.8GHz?"
I should've said diagram, but I'm pretty sure it says >1.8 GHz
Notice in contrast how it states the GPU clock as just 800mhz
