PS4 has 8 GB OF GDDR5 RAM

That table is quite old though. Technology has the habit of getting cheaper.
See I think it's possible the cost of including a kinect 2.0 in every box would make up for it though, which is why they'd have to go a little cheaper on the ram.
I suspected this may be the case.
Your PS3 ram count is wrong.
This must have been a very recent change, then.
2 Years ago this was just crazy talk ( the Embedded DRAM still is )

I get the suspicion that they didn't hold off on showing the console just to save it for E3, but because they may be doing last minute revisions to accommodate the more complex motherboard. But I don't know shit, just speculating.
That would make sense given that very few leaks seemed to indicate 8GB GDDR5.
I just remember that one that Sony promised to aim for 8GB if they could.

You're only showing system RAM, so your figures are not accurate.

16 4 Gbit chips (sandwiched, 8 per side) seems far more likely.That's one thing I honestly didn't expect. That's 32 chips! Board is gonna look like a 90ies arcade PCB.
man looking by your post history, please tell MS to put advanced RAM in next xbox . Otherwise many will be very disappointed like its investors
are you saying what we saw today was on 4gb?
I'm hyped.
Those games were probably using less than 2GB.

they are having a stacked set up like Riggby has been saying all along

I thought I read somewhere that GDDR5 can't be stacked?

about the RAM... i found this on the web. it's the only thing that lists a price of ram for gpus released in 2010
The 6970 is the GPU we should be looking @ because it has the same bandwidth rating as the PS4 rumors. 176GB/s and they required 8 chips to get 2GB on their board.
8*2Gbit (256MByte) chips rated @ 6GHZ and they ran it at a slower rate. (ran @ 5.5GHZ on a 256bit for 176GB/s bandwidth but the chips were rated for 192GB/s)
The ram cost was $48.57 for 8 chips. That's about $6.07 for each 256MB chip and this for a card released in December 2010. It's been 26 months since the release of this card and GDDR5 has gotten cheaper to produce now. 6GHZ rated chips are on the GTX660/660ti/670/680/7970. It's a mature spec and the fact that it's on all nvidia's cards from the 660 & up shows it.
Sony's GDDR5 would be @ 5.5GHz if the 176GB/s holds up and it's on a 256bit bus, which seems like the obvious thing they'd do to feed the GPU.
16 ram chips would be needed to get 8GB of ram @ 512MB densities which is the highest density we have today. The nvidia Tesla k20 has access to 12GB ram on 24 chips which gives us 512MB chips density f/ 2013.
http://vr-zone.com/articles/nvidia-...-k20-2013-geforce-and-quadro-cards/15884.html
16*$6.07 = $97.12 @ Dec 2010 prices. We don't know the 2013 prices, but you can be damn sure it's nowhere close to the extreme prices we got when these chips were top of the line and were only produced for the radeon 6970 @ this time. We now have these chips made for millions of cards from nvidia & amd. Sony is buying LARGE qty's of this mainstream spec ram. That's millions upon millions of chips being bought by Sony alone. I wouldn't be surprised if they're paying like $50-60 total for the 8GB of ram.
this site estimates the bill of materials for a nvidia quadro k5000 in the lower $200 range and you know the ram won't be making up 50% of that cost because it's just a GTX 670 4gb with full compute performance enabled.

it's a random site i found, but it's something and that's better than just spitting crap out of thin air.
I really just think we've been overstating the costs of GDDR5. yeah, it's expensive in comparison to ddr3, but it's not as expensive as it used to be. we find 1 GB GDDR5 in $65 retail gpus

This is all very exciting for someone who still has interest in console gaming. Even more exciting to see what Sony's very talented first party studios will do with that amount of fast RAM. Bring on more games!

That seems more sensible. Didn't realize 4Gb chips are available. Then again, it's been a while that I looked into it.

Is unified memory good or bad?
It's bad right?
It's bad right?
That's some solid work on the price estimation. In 2011 I predicted ~50-60€ for 8 GB GDDR5 in late 2013, seems like I wasn't too far off.
Pretty much entirely good, when it's this fast.

I believe the addition of the extra 4 gig was an extremely late decision, hence the lack of any images of the unit, the probably have to reconfigure the cooling system and the chassis accordingly.
I have him on ignore. Less crap to deal with. But his tears were delicious tonight.
yup I think so to.
That is really impressive.
I am fucking gobsmacked.
Two questions. People are shitting their pants over 8GBDDR5. Is there a current equivalent gfx card on the market? How many 680's slapped together would achieve the same power? Clearly I'm no tech head but in layman's terms what are we looking at here?
Also, with regards to the gif. Is it confirmed to be in-game?
Regardless, I am buying a PS4. yay!
That's Ninety-Nine Nights, not Dynasty Warriors.
Having armies consisting of a million troops would compromise Koei's commitment to strict historical accuracy.

It's good. It means developers are free to distribute the RAM across the GPU and CPU however they want, outside what the OS is taking.
If a developer wanted to use 7GB for the GPU and the rest for the CPU, they can.
This decision still doesn't make much sense to me, the GPU won't be fast enough to take advantage of more than about 2-3GB of that RAM, and this memory speed just isn't that necessary for the CPU.
a 680 is still faster than this.
a 680 is still faster than this.

Sooo.. is this an accurate representation for us layman who don' know jack shit about hardware specs? Because if so... I said god damn!
dammit Sony!
Sony cray....

It was played on stage.
RAM capacity isn't power. It's capacity. In terms of GPU throughput, the PS4 is still below a single 680.
you're missing something then. Because their engineers wouldn't have gone with 8GB of ram if it was pointless.
Dedicated memory is not as effective as unified memory in a closed platform such as a console.
It was played live, right before our very eyes.
Well you WERE right about 8GB.

What does the 8 GB GDDR Exactly mean??(in a conventional sense) I know that developers were craving for more ram. But Its still not completely clear what developers can benefit besides enormous space for texture work and enormous worlds. But I cant exactly picture what can be achieved does anyone have an simple example ??

GDDR5 better have dropped like a rock in price or Sony's gonna lose a fortune here.

Was all of the Xbox 360's ram being GDDR 3 pointless?
Or the rumoured Durango ram all being GDDR 3 pointless?
this is what i was wondering. it is a brilliant marketing tactic though.
Then I think it lends credence to the some people's assumption that what we saw today was based on older code and older specs (3.5GB GDDR5) especially KZ4 (and personally perhaps even Watch Dogs). It means games are about to go through some big changes by the time E3 rolls. It also means that second generation games built ground up to take advantage of 3.5+ GB of RAM will be the first proper show case for the system.
Why wouldn't technology prices drop by 50% or more over 3 years?
