[QUOTE="ronvalencia"][QUOTE="Shewgenja"] Eh, not really sure how anyone else feels about this, but to me, the conclusion is pretty clear. Whatever it is that MS is running besides games on their new system, it has them excited enough to spend resources on it instead of making a more straight-forward machine. I'm not entirely sure what people's expectations are for a machine that is running DDR3 in this day and age, but keeping up in any meaningful way with PC development really isn't one of them. Whatever they are throwing this heap of RAM at, it's not going to have the kind of deep bandwidth needed for games in an evolutionary sense. Of course, this shouldn't be necessarily painted as doom and gloom either. Obviously, just the fact that it is using a DX11 era gpu in the first place is no small step forward from the 360. It's just that this isn't a system designed to go toe to toe with the Sony machine in, oh let's just say, five years down the road. How you take that statement, is entirely up to you.ShewgenjaAMD's Cinema 2.0 voxel raytracing/raster hybrid demos needs alot of ram (i.e. +8 GB). I'm curious, though. What specification is that RAM they are using in that Demo. With DDR3, you are still looking at a diminishing pipeline for that kind of "heavy moving". It's neat to think that a console would go in that direction, but I shudder to think of what kind of framerate we are talking about here.
115.2GB/s from 900Mhz GDDR5 (1GB or 512MB). +8 GB refers to system memory with memory speed relates to 2008 era PC hardware i.e. DDR2 type.
4850 has GDDR3 with 63.6GB/s

Not necessarily, The 5gb of DDR3 can store most if not all the video and relevant game data into memory allowing faster asset loading and allowing more options. while having less faster memory would still need to swap out data and stream. which has been an issue for current consoles.[QUOTE="04dcarraher"] Not necessarily, The 5gb of DDR3 can store most if not all the video and relevant game data into memory allowing faster asset loading and allowing more options. while having less faster memory would still need to swap out data and stream. which has been an issue for current consoles. tormentosBut it takes way more time filling it than GDDR5 would take,the same data will not stay for ever on the ram,it changes guess who deliver the changes faster.? Like i already say the 690GTX has 4GB of ram,which basically max out every game out there,Orbis will not have such a powerful GPU,so i don't see the point,and todays consoles has that problem not only because of the lack of ram,but also because of slow DDR3.
Where do get it takes more time to fill it? that is all dependent on the cpu and bluray/harddrive. Look at Pc's using DDR 3 at 1333mhz only being able to do even with 128bit dual channel only can move 21,000 MB/s and yet can load games and game data much faster then the PS3 or 360 which their memory is faster. Point is that if you load most of the data you need from the start of the game you will not see any real difference between ddr5 or ddr3.
One of the rumored specs, the chart shows the Durango having 68 GB/s memory bandwidth and through the ESram 102 GB/s. which is 3x faster then average DDR3 speeds, Which means its most likely going to be using 256bit GDDR3 around the 1000mhz range to get the 68GB/s. which was fast enough for the most of the Geforce 8 series.
