The weird blurriness in DF's PS4 images is hard to explain indeed. I know they said they had some kind of capture issues. But I'm not sure capture issues alone can explain the difference here. Looks like actual image IQ loss due to some filter. Like some kind of effect gone wrong.

Carmack just tweeted this: https://twitter.com/ID_AA_Carmack/status/304607913853476864 "I can’t speak freely about PS4, but now that some specs have been made public, I can say that Sony made wise engineering choices."

I would add powersupply and cooling system. Heavy duty cooling system and a high quality powersupply like the original PS3 had isn't cheap.

We are talking about companies who routinely build and sell boards near $1000 just to have bragging rights for thier flagship designs. I am pretty sure cost is not the reason why they do not use edram on thier high end. For the low end to midrange , you might be able to make that argument...

Like it has been said before... lots of PS3 games already do this. People are making mountains out of mole hills.

High clock speeds are generally only attainable by having very long pipelines with very short stages. Essentially you can get your clock rate up by doing less work per cycle. A more sophisticated cpu with a lower clock but a more efficent pipline can achive much greater real world throughput...

Since when did that become a doubt? The chance of that is zero. It will be some form of edram.

It is easy to say that now about the PS3 with hindsight. But 7 years ago, the proponent s of the PS3s design were saying a lot of the same things about how much more efficient it could be per core because of many dma fetches in flight etc, 2 pools of ram etc. And it's not that they were...

We have no reason to currently think core efficiency will be that high. All we know is bandwidth as it exists in that design is fairly low. And the added some work arounds to try to tackle this problem. Whether or not it is an actually efficient desgin we probably won't know for at least a year...

Only 2 of the 4 DME units have compress/decompress hardware if I understand correctly. My impression was that it would be used more for copying buffers between the edram and ddr3 than for more efficient texturing.

Just FYI. Enterprise editions of Windows Server 2003 supported upto 64GB of ram on 32bit x86 CPUs with PAE extentions. 32bit windows itself was not the wall. I recall reading MS considered increasing the adressable limit in XP too. But it broke a lot of drivers so they decided no to.

Ummm, that hypothetical design already has 2 cpus and 2 gpus. And you are trying to claim it needs another additional chip to support computation...

Ya, there are PS3 games that already do that. VirtuaFighter5 when the game is set to 1080p is the earliest example I recall noticing it on. And that with no dedicated hw scaler.Nifty sure. But hardly ground breaking.

I say not a chance. Maybe the dev kit versions might . Final version would make no sense cost wise.

Pretty big risk to gamble a successful Xbox business model on 2 new peripherals, surface and a new tablet. MS does not have a good track record launching new hardware. Also their first surface device already bombed. Besides the Xbox, nearly every other product line has been a flop. Designing...
