Your choice of NFL teams is crap.

That has yet to be seen. Cross play hasn't helped it yet.
| superchunk said: ok, By now everyone knows PS4 has 8GB of GDDR5 RAM. Most should know that up until yesterday's meeting ALL rumors stated that it would only come with 4GB of GDDR5 RAM. Most should also know by now that even developers have been working up until NOW only 4GB of GDDR5 RAM for games, though dev kits had 8GB which is normal as dev kits always have more RAM than retail units. Finally, Most should know that ALL rumors for neXtBox have it also having 8GB of RAM, however its DDR3... slower is biggest difference. So here is my possible theories. 1) Sony realized they'd have 1/2 the RAM of their competitor where overall the rest of their system is equal or greater. So they simply made a last minute decision to go to full 8GB. This also means that likely the next round of dev kits will have >8GB GDDR5 ram so the devs can appropriately code for the full amount available to them while still having RAM available to their dev tools. 2) Sony always planned on having 8GB of RAM in the final retail unit, HOWEVER devs and others only knew about 4GB because the rest was secured solely for all the always on information behind the games. (i.e. 4GB is reserved for games and 4GB is reserved for OS) Think about the features they talked about. Always recording your gameplay so you can instantly share any screeshot or video segments. Always running opportunity to stream your content to someone else who can even play your game at will. Downloading and playing simulatneously. Cross game features of video and/or voice chat. As well as others. This all takes up a good amount of resources, especially RAM. Additionally, even though neXtBox has had 8GB rumored all along, the accompanying rumor is that it will eat up 3 or more GBs of that RAM for the OS as well. What do you think? |
my question = how can a system have GDDR5 memory as the main RAM memory?
I mean GDDR stands for graphics memory ... not the main memory...and btw: Am I the only one who thinks that way ??? :/

Short story, GDDR is an improved DDR designed for applications needing large ammounts of bandwidth. Of course it has it's downsides but that's basically it... memory is memory after all.
OT - I think #1 is correct, more or less like MS did with the X360 last gen. This and pressure from the developers.

well I guess for a system which is centered around the GPU (much like the wii u) it makes sense... thanks :)

It is also complete nonsense.
Look, WE KNOW many of the details. If only people would not have such a short attention span.
A few weeks ago, there was a thread about the fact that Sony had a 2.7G cap in the memory pool for gpu use. Much was speculated about those 2.7G. It is clear that this cap was introduced to leave sufficient room for the rest of the system ON A 4G machine. The PS4 was planned as a 4G gddr5 machine.
What made Sony change to 8G? That is anyone's guess. What should be perfectly obvious to everone here is the FACT that Sony was in constant discussion with devolpers (who DID USE 8G prototyping machines). Apparently experience showed that there would be a clear. mesasurable performance advantage to break the 2.7G cap on the gpu (once developers also started to use the "rest of the features" (streaming, cross talk, etc, everything that eats memory essentially). The clear disadvantage was enhanced costs of doubling the ram chips to 32 units which requires a pcb redesign.
Subtracting the disadvantage from the advantage, the result apparently was a number > 0 (it also majorly pissed off MS, who apparently did not see that coming).
"2) Sony always planned on having 8GB of RAM in the final retail unit, HOWEVER devs and others only knew about 4GB because the rest was secured solely for all the always on information behind the games."
That would be my guess. They were playing it safe because they weren't yet sure about how much RAM all the other stuff was going to take. It gave them wiggle room to add anything they wanted to the OS functionality.
Also, does anyone have an idea how much 4GB of GDDR5 RAM would cost Sony?

I bet. I hear a RAM-pack add on is already in the works at Microsoft. Ala N64 and Sega Saturn.
Seriously, this gen is becoming the gen of teh RAMz hype.
Teh Cell = RAM
If the PS4 can stream/record/do all the other social stuff with just 4GB ram and still display those great visuals, I imagine the extra 4GB will be fully utilized by games. And remember, OS footprint will go down over the years.
i know next to nothing about OS design but i do imagine the OS will be significant in size. it records the last 15 minutes of gameplay for easy sharing. background download. console sleep mode. gaikai integration. multiple user logins. 3D camera input. ...having 4 for OS seems huuuge but not impossible.
..but that's still 4x larger (for games) and some multiple of faster than wiiU which is a really big discrepancy. and even if 4Gb is reserved now there is still room for optimization down the road like how the ps3's OS shrank in halfish if i remember right.
