A cynical part of me feels this "8 > 4" will be key in a bad way for Sony. I mean how many people will be informed of which RAM is actually faster? They'll look at raw numbers.

Correct. Even if the old 1:1.5 is wrong. And as I wrote above about the rolling scale for OS memory reservation. 3, even taking into account something insane, is huge.
I'm gonna be skeptical on this--especially the CPU bit. Even Phenoms beat Jaguar cores, and i5 is the better choice for gaming.
It also seems like a lot of the CPU work will be offloaded to the GPU (and that mini, pseudo compute GPU thing in PS4), so I wouldn't put too much stress on the CPU bit, but we'll see.

So for the technologically unaware, can you explain to me if this difference in RAM matters?
They'll also look at the games lol.

Depends on where the develops want the bottleneck. You can have plenty of RAM and no feasible way to move the data around quick enough (bandwidth), you can have plenty of RAM and have too little horse power in the GPU to process the data (compute units, stream processors, etc.), you could also just not have enough room to fit all your code and assets (RAM size).
You can design and optimize around all of these issues.
7900GS? That was a fairly decent card for it's time, judging by benchmarks..
Why is Doom 3 so wack on the PS3, if the 7900GS has such impressive framerates on the PC?
RSX is a gimped 7800GTX - half the ROPs and lower memory bandwidth. Definitely not a 7900GS. It's more powerful than a 7600GT but not by much really.
You're tired of seeing ignorant comments about hardware performance? You're in for a long year.
Sony could have an advert comparing a sports car with a bus.

lol, yeah, that too.
How many people outside GAF will even know those numbers?

- If you're multiplayer gamer, it's simple. You just wait and buy the system your friends are playing on.
- If you're a single player gamer, you get the system that offers the best games.
If you're both... well, then you're fucked. You'll just end up buying both. Like I did this gen.

Interesting analogy. So the smaller, faster RAM, is better than the bigger slower RAM?

So now we know the core GPU of the PS4 doesn't even match a stock clocked GTX 580, a card made more than 2 years ago, and in fact is based on a underclocked laptop model, making it closer to a GTX 570/480 in all likelihood.
We now know one thing for sure. Do not expect the Samaritan demo to run 1080p at 60 or even 30 fps on the PS4, even with antialiasing or tessellation turned down. We will be lucky to have on 720 or 900p in medium settings.
To those hesitating whether or invest in a high end PC compared to buying these consoles: Go for the PC, and do not turn back. Current high end(in fact, medium end) PCs of last year already surpasses both the PS4 and the Xbox 720. The gap will only grow larger every year.

It will be used by fanboys on message boards, but since when did consoles used their specs for advertising?

Well... judging by how "well" GPUs ran stuff like FEAR back when PS360 came out (IIRC) and how a 7970m runs Crysis 2 extreme (at 1080p I guess) plus extra CUs and GDDR5 I guess we'll be fine?
Many have been suffering for the past year already D:
Remembers when people expected 4TFLOPS performance out of the GPUs and 8GB GDDR5
It is your duty to make sure everyone at Gamestop understands this fact when someone asks a clerk this question.
Highest i've seen DDR3 is 2000Mhz, DDR5 is at 6000Mhz in the last batch on Nvidia cards.

Indeed. I mean I get why some people are excited, it's been so long since a new console generation has been out. But personally I'm quite disappointed, I expected something much better than a mid-range PC from 2011. Oh well, maybe the Steambox will blow both of them out of the water when it drops. Highly unlikely but hope dies last
A lot of people that are disappointed with the rumoured specs seem to be comparing console tech to PC. This is a common mistake, PC games have an extra layer of abstraction that makes them heavily unoptimised 'compared' to console tech. So take these specs with a pinch of salt, they have incredible potential.
GDDR5 has huge bandwidth advantages over DDR3.

You're forgeting audio dsp, which does what an entire i7 core can do at audio.
Graphically I think you'll be able to play Orbis ports fine with
Sandy Bridge the weakest desktop i3
4GB of ram
7870 GHZ edition
What's wrong with it? They make one of the closest skins to stock Android and they let you root/open up your phone way too easy... Maybe you're thinking of 2 years ago when they were really slow with the updates and had heavy skins?
256-bit for PS4, I assume.

DDR3/4
Dual channel DDR 2666 is ~42GB/s
Triple channel DDR 2666 is ~63GB/s
http://www.hardwaresecrets.com/prin...ple-and-Quad-Channel-Memory-Architectures/133
256-bit GDDR5 @ 1000Mhz is 192GB/s
So the differences can be as little as 2.3x or as high as 5x with typical numbers. For example, triple channel DDR 2666 is not common yet, in fact I just see 1600.
Scale according to the clock rate for both. My number be off, feel free to call them.

You won't need an i7. A Core i5 @ 3.2 GHz already has twice the clock rate (more than making up the difference in number of cores) and considerably more IPC.

Totally, and there is stuff that we still don't know yet, and this has Been said many times before, 1.8TF on a custom closed box is totally different than 1.8TF on a PC.
More Ramz for the Kinect lol
But seriously, what if 720 comes with Kinect and they expect the Kinect to be always on for motion controlling (e.g controlling the OS, Voice Commands and etc). And of course the 720 being a DVR cable box also, so switching between a game a TV is needed, also while maybe a programme is recorded in the background, while the Live Store is open, and the web browser is also open.
Sorry if I sound ignorant but how does that translate into real world rendering? Take for example a huge open world like Fallout ot Elder Scrolls. Which system would benefit more, the one with a faster bandwidth or the one with higher capacity ? Those differences in speed are huge, surely MS is doing something to compensate such as eDRAM? Or software magic ?
Let's take some more realistic clock speeds, like PC-2133
256-bit DDR3/4 would make 68 GB/s
Do you honestly think the new Kinect isn't going to be in every single new system box?

These specs wont matter to the majority of consumers, except in how they manifest themselves in games, os features, graphics, etc.
Karak

not really. i wanted 2.5tflops or more. I am willing to pay. But I guess this is more realistic and is fine. but I am not buying PS4 1.8fltops vs 1.2flops on MS. thats big difference.
Not really. GDDR3 is faster than DDR3 and GDDR5 is twice as fast as GDDR3.
This is a better answer.
Real world rendering depends entirely on the software. There are different approaches to how you use VRAM, how you use system RAM, how/what you cache and where you cache it, streaming data from the disk... There's not a black and white answer to which one is better.
Microsoft is almost certainly going to have eDRAM again.

They do, some in this thread are just too blind to see it. I don't know why people think MS is stupid, software is their business. You really think MS would reserve 3GB for simple shit that the 360 already does?? I'm 100% sure they will have new features and capabilities that no one in this thread has even thought of yet.
Indeed, the things devs will pull with both these consoles will blow minds. Can't friggin wait.
No really I can't
I think you'd be talking about two sides the OS - a hard 'game OS' with strict resources, and then something more windows-8-y for apps where you'd have that kind of looser application closing.
But anyway, I'm not sure the suggestion is that any one app would need >2GB of memory. But presumably if MS did want a certain level of software compatibility with Windows 8 or RT, they'd want you to be able to run more than one app at once. How much RAM could afford that kind of experience? And they might have an eye on future generations of app for a 5-year box.
Karak's suggestion of an inflating OS depending on game features could make sense too. Although I dunno what optional gameOS features could potentially add up to 1.5GB of RAM

Yes, eSRAM or eDRAM is a high speed buffer or cache, the rumor is 32MB.
Quad channel DDR4? I guess that makes more sense, though this is all cutting edge as far as I know.
So 4x2GB quad channel or 2x4GB dual channel.
Edit: Interesting, wonder if DDR ever get near the theoretical bandwidth as you increase the channels and clock?

That's what I was thinking. The PC comparisons I've seen so far seem rather...off.
+1 on that. They will differentiate themseles with their software feature set, as they did last gen. and it will be a big fucking difference, as it was most of last gen.
Durango to use Floppies CONFIRMED!
$50 vs $150 for 8GB of 2133 vs 2666
