  "First, we added another bus to the GPU that allows it to read directly from system memory or write directly to system memory, bypassing its own L1 and L2 caches. As a result, if the data that's being passed back and forth between CPU and GPU is small, you don't have issues with synchronization between them anymore. And by small, I just mean small in next-gen terms. We can pass almost 20 gigabytes a second down that bus. That's not very small in today’s terms -- it’s larger than the PCIe on most PCs!

• "Next, to support the case where you want to use the GPU L2 cache simultaneously for both graphics processing and asynchronous compute, we have added a bit in the tags of the cache lines, we call it the 'volatile' bit. You can then selectively mark all accesses by compute as 'volatile,' and when it's time for compute to read from system memory, it can invalidate, selectively, the lines it uses in the L2. When it comes time to write back the results, it can write back selectively the lines that it uses. This innovation allows compute to use the GPU L2 cache and perform the required operations without significantly impacting the graphics operations going on at the same time -- in other words, it radically reduces the overhead of running compute and graphics together on the GPU."

• Thirdly, said Cerny, "The original AMD GCN architecture allowed for one source of graphics commands, and two sources of compute commands. For PS4, we’ve worked with AMD to increase the limit to 64 sources of compute commands -- the idea is if you have some asynchronous compute you want to perform, you put commands in one of these 64 queues, and then there are multiple levels of arbitration in the hardware to determine what runs, how it runs, and when it runs, alongside the graphics that's in the system."

Oh right gamasutra not neogaf.

Alot of the parts are identical to the gamasutra one. All his quotes I googled occured earlier somewhere else, but when you say its worth reading I will do that.

Gamasutra shared some info last week and at the end said they will publish the full interview soo.

This is the full interview.

well I didn't understand any of that but hopefully it means prettier games running at higher framerates lol

To the end user. It sure does, which is all that's important in the end for a dedicated gaming machine as the regular consumer doesn't even know what a CPU, RAM or GPU even is, all they care is how awesome games look. :p

From a modding perspective though, the PS4 excites me, I would love to mod one, install Windows and call it my new HTPC /Media Center under my TV, with some emulation on top of it!

One thing I don't get on console games is why can't I customize the FPS and resolution?  I mean it's scalable on PC so if I want non-HD running at 60fps I can have it.  They know the console specs and can program a shorter range but there's no reason not to have it at all in SP (I understand MP because higher FPS could mean you react faster).

Because, people want better graphics, constantly. - That's been the case since computer gaming has begun.

Remember, consoles are fixed hardware, they don't change in compute capability, so what developers have to do is make concessions in some areas but make it up for it in other areas and introduce new tricks for more efficiency. (Impostering, Better texture compression, better texture or model streaming etc'.)
Or by making concessions in some areas like resolution and framerates to improve it in other areas like lighting, Shadows, Texture resolution etc'.

Besides, most people sit meters away from a TV, chances are most people only have a 32-42" LCD/Plasma and from those distances people wouldn't notice the difference between 720P and 1080P anyway.

It's a different ball game on the PC, most people sit up close to the monitor and they can see the tiny details, not to mention PC developers don't need to make concessions in framerate or resolution because the PC essentially allows for far more flexibility with it's constant improvement in performance, essentially giving them essentially unlimited performance.
Hell, PC gamers are a funny bunch, they will whinge and whine and complain till the cows come home if a game doesn't push their PC hard enough. (Like with Crysis 2.)

However, with the 16x jump in the amount of Ram this time around instead of last generations 8x jump, I would be surprised to see games dropped from 1080P @ 60fps down to 720P @ 30fps untill towards the end of the generation, where developers start to feel the limitations of the consoles (And PC gamers cry in agony at horrible ugly ports again.)

Then what is it then? It's certainly no match for my PC. No, please, do elaborate.
