Call me for the Avatar GFX

confirmed xbox next dumps amd for nvidia. resources say that the reason behind nvidia not mentioning xbox in several articles about the ps4.

yes im lying lol. i just like when people say stuff is confirmed

Nope. I mean PS4. GDDR5 is just insanely fast DDR3 with 5ghz fast bus instead of 1 ghz.

Which is why its more expensive. But its possible to replace it with stacked DDR3 which has 1024 bit instead of the 256 bit of GDDR5.

So you can lower the frequency, wattage, mainboardsize and you can start to use the cheaper GDDR5 rejects.

Wake me when Xbox 4/5 comes out. ^^

They won't make it in time man ^_^; AMD hasn't even shown similar designs in anyway. Maybe the next one, analysts that predict the 8th gen being the last gen are retarded because they have no idea how far ahead tech will be past the 2015 point.

That's good guestion indeed.

Also this makes the PS4's GDDR5 look like old gen tech already.

I'd guess he's argueing a "slim" redesign down the line, even then though that seems highly unlikely.

Additionally I still don't get why people are calling ram with better bandwith and worse latency FASTER. (Let alone insanely fast)

Ram with worse latency is slower.

If you were going to give GDDR5 a term vs DDR3 it wouldn't be faster, it'd be stronger.  It's like a truck vs a race car.   The Truck is slower (Latency) but can tow more at once.  (Bandwith)

lower latency is good for codes and higher bandwidth is good for carrying graphics data, so GDDR5 is faster for carrying large chunks of data at once but slower for quick fetching of smaller chunks. I honestly don't think the average consumer will know the difference anyways though, people argue for the sake of arguing sometimes.

as Kasz216 said I am talking about a slim redesign maybe in 5 years time

@Kasz

What makes you say that its unlikely ? Costreduction potential was probably a priority, this time around. PS3 is a disaster in that regard.

Sony wouldn't have used GDDR5 at all if they don't see a way to drastically cut costs later. It draws alot of power and through stacked Ram and a single chip PS4 will be tiny by the end of the gen. Sony are going to switch to stacked as soon as it becomes cheap enough. There is no reason why they wouldn't do it if they can. Saying thats unlikely is hard to understand looking at things. So I assume you know something I don't ? Please tell me what am I missing ? Or is that assumption  based on a feeling ?

Latency and bandwith. So why used I fast ? Because through bandwith you can transport a higher volume of data in a shorter timeframe which is why GDDR5 is considered faster aka More Data available per frame.

Latency is reaction time. Lets take a look at cars.

DDR3 is a lightweight tuned Volkswagen Golf with Schumacher on the wheel its faster from 0-5mph because the driver steps earlier on the pedal. GDDR5  is a Bugatti Veyron with a 500 pound guy behind the wheel. Schumacher will win on very curvy roads. Like a road through the Alps. But the Veyron with the 500 pound driver is still faster in 99% of the (gaming related) cases.

So yes the Veyron wins in  the (gaming related) cases even with a shitty driver. 

Also faster is used because it actually is faster doing a thing. And I mean the technology runs faster. One thing does something 1 Billion times per second and the other does it 5 Billion times.

So yes saying GDDR5 is faster than DDR3 is a perfectly correct way to describe the situation. Sure its sometimes slower but mostly not.

The Latency issue is not a big issue anyway I assume you are hinting at DDR3vsGDDR5 debate coming from nextgen talk ?

Caching in the CPU solves most problems. Throwing way more bandwith (HP) at one problem than necessary also. And yes the Latency issues are big compared MHZ to MHZ and Bit per Bit but are really not that big of a deal with 5 times the clockrate and 2.5 times  more bandwith. Even if the per MHZ latency is 6 times higher its not as bad if you have 5 times more MHZ.

But when I think about it MS reason for their Ram choice makes sense. Kinect might suffer big time on a PS4 the latency would really be noticeable here. As the Kinect needs alot smaller packages fast the GDDR5 larency would add up each time the software needs another package from the Ram. The lag would increase alot. This might be the reason for Esram+DDR3 in a console.  

I see, I think they won't do it just based on design principles, if you look at the PS3 super slim, even though they have tidied it up quiet a lot, it's more of a shrunk than a redesign and I'm not expecting them to introduce actual new tech for the PS4 once it's finalized hardware.
