I doubt GCN is that inefficient about mixing GPGPU and graphics tasks normally (?) I thought it could mix them around on a pretty finely grained level.
I'm sure this probably does have something to do with task scheduling though.
A cluster of up to 4 Compute Units share a single 32KB L1 instruction cache that is 4-way associative and backed by the L2 cache. Cache lines are 64B long
and typically hold 8 instructions. When the cache is full, a new request will evict the Least Recently Used (i.e. LRU replacement) cache line to make room for
new instructions. The shared L1 instruction cache has 4 banks, and can sustain 32B instruction fetch per cycle to all 4 Compute Units. Instruction fetching is
arbitrated between SIMDs within a CU based on age, scheduling priority and utilization of the wavefront instruction buffers.
Dual Asynchronous Compute Engines (ACE)
◊ Efficient multi-tasking with independent scheduling and workgroup
dispatch
◊ Parallel operation with graphics and fast switching between task
submissions
◊ Support of OCL 1.2 device partitioning.

Seriously, i mean what good games are there were Kinect makes the experience better? And i better not hear people mention voice commands.
no bc means im not buying anymore psn games. ever.
I think im going pc next gen. Its going to be a safe bet if these numbers are correct.
yup and then some, and there's nothing OMG FABLEDDD about it.So how much better is this fabled PS4 RAM we're talking about here?
Will the RAM's speed honestly makeup for its lack in volume?
It is almost no point to work out the overall strength because we will never know how much they will reserve some part for OS untill near launch. ie 3.5GB vs 5GB or 3.5GB vs 7GB are big different imo.
For now we can do is the speed rather than capacity. The rumours suggest that Orbis has more advanced speed on GPU and RAM with same CPU.
Depending on how easy it is for devs to code for the 720, we might the max the system can do in the first few years. The only interesting extra piece of tech in the system is the ESRAM. Otherwise it's a pretty straight forward PC with a Kinect attached to it and an underpowered (imo) GPU in comparison to what Sony is offering.
We might get a full spec leak before E3 if possible.
After the proper announcements of course.
Interesting question, I wonder how devs have to manage the two different types, or does it even matter in the final release product as long as it fits the min, specs required?

With the included camera, move controller and new DualShock. I'd put the price at $450 minimum.

ipads can be used for more things and are 100 times more portable.shucks they downgraded the gddr5....
sony planning to sell this for $399 and turn a profit with the first-second games bought? i see no problem hitting $399, the specs are not impressive. by the time PS4 launches, i believe high end gaming laptop will surpass the performance with ease...
too conservative, should have built for $499. people pay for ipads at a higher price.
I still expect the drive to support BDXL by launch, especially with Sony pushing 4K content.
deader than dead.
lol Why do people keep trying to directly compare PC to closed systems? With these specs, Orbis/Durango are going to output some ridiculous looking games and I can't wait.
Higher frame rates.
There are several PC games already this generation that wouldn't fit comfortably on a Blu-Ray. If we are to surpass that, then it's likely that a lot of games will be using the 50GB discs, or more than one 25GB disc.
Easy. They'll target 3.5 GB DDR3 RAM and all will be good.
What is BDXL? And why is it better than the BD in the PS3?
The only concern for me is that multiplat games will have higher res textures on Durango than Orbis, I don't see any way the opposite will be true. Faster Ram can't compensate texture resolution can it?

lol you wish. Luckily for me I'll get my 1080p24fps pre-rendered cutscenes, I wager they'll get that HDMI 2.0 spec out and for next gen consoles so 1080p30 and 1080p60 3D cutscenes can be played.

Nor do I.I don't have a single game that comes close to 50GB in my PC game collection. What games are pushing that limit? I'm not saying you're wrong, I just haven't ran into any, personally.
The only thing that caught my eye here is that the GPU is formatted at 14+4 CU. Can someone explain what that means exactly? Is the extra 4CUs the "Compute unit" the Eurogamer was talking about? If so, that means that the compute unit flops are rolled into the 1.82TF count, right?
Does anyone care to guess why they did this instead of making all 18CUs available for whatever? I remember Durante was making TF/BW calculation for this hardware, saying that its ratio there is higher than AMDs GPU normally are, so is this why they dedicated the 4CUs for a non rendering purpose? Because they'd otherwise be wasteful?
*edit* OK, I see this is already being discussed.
BDXL allows for 100GB and 150GB storage on a disk. Necessary for 4K videos and 9.1 lossless sound. Maybe even 1080p48 3D for movies like the Hobbit.
Devs can put 1080p60 3D content for their pre-rendered scenes, Dolby True HD and DTS MA game soundtracks, and more higher quality textures.
Nor do I.
The poster you quoted won't be able to come up with a game that is larger than 50 gigs unless the pulls the whole 'Skyrim Modded with ULTRA insane wasteful textures' card.

So RAM bandwidth is downgraded? I'm reading confusing posts here.
Yeah but the ps4 won't have this plastered all over it. $399 is the least it will cost.
Let's not forget it allows for an easy crossfade between two completely different sceneries which is a typical thing you could need in a cutscene and is a nightmare to pull off completely in realtime.There is little disadvantage to using a prerendered cutscene. It looks better, allows you to load the next section, and doesn't even cost that much to do if you do it in engine like uncharted.
Then I really hope it has BDXL. 1080p48 looked incredible in the hobbit. It would be ridiculous if Sony's premiere AV device wasn't able to support that.
up to 100GB on quad layer discs, will probably be required if they ever ship 4k movies on bluray.
Either Sony will use BDXL and devkits simply have a standard drive, or they think perhaps there is no market for 4k on disc (they've been talking about downloading 4k stuff) and so won't bother investing in it?
The cost isn't just the drive but also the printing cost of discs.
no need to wish, 3D televisions did not sell well at all. They're largely considered a flop and the new focus will be on 4K.

I think Max Payne is in the 30GB territory because it uses some HD video for cutscenes and I think the Force Unleashed 2(?) is inexplicably enormous. Maybe some MMOs + all their expansions get up there but even games with optional HD texture packs don't typically come anywhere near 50GB.

single layer (25 GB) or dual layer (50 GB) discs
Welp. Time to enjoy either:
a) low texture resolutions
b) increased disc manufacturing costs -> higher game prices (hopefully they go full digital as well, like with Wii U, so this isn't a factor)
c) multiple disc games
Charging more than $399 is suicide. Microsoft is going to get there again, and Sony had better match them this time.
Now, if Sony can get two controllers and a camera in there and still get to $399, then that's fantastic.
I need a translation into layman. Maybe add in Durango/U comparisons as well.

WHOA!!! So what speed would you guys think can be in the system if it does have a BDXL drive? At least 6x?
Please stop comparing PCs to consoles.If this were the case we would see PC video cards with 8GB of DDR3, you don't.
