Sad thing is all of that RAM will go to waste.

GDDR RAM is designed to transfer large chunks of data like textures, frames, shaders, etc. This is why they are commonly used in video cards.

The thing no one tells you is that GDDR is awful when it comes to sequential R/W. This is why gaming PCs are built with GDDR for video cards and DDR for system memory. Your system memory has to swap around millions of variables constantly while running.

Go buy a cheap flash drive. It will do great transferring large files. Try transferring a large number of smaller files - the thread will lock up/slow down.

Nintendo and MS made the right choice with DDR3/eDRAM. You get the benefits of sequential R/W while getting a part of the benefit of high bandwidth. Using the right system RAM is essential today, when the way the OS works is just as important as the games.

RAM cost about nothing, its cheaper than buying games nowadays

$399 won't mean a big loss at launch..

they are launching late 2013..

This isn't the same RAM you're buying on Newegg...

The new $1000 Nvidia Titan GPU has 2gb less GDDR5 than the PS4..

Oh God...

... define 'awful' please.

GPU GB sizes are not related to RAM sizes.

mate....

the GTX Titan is the company's most powerful single-processor GPU chip to-date, boasting a staggering 2,688 CUDA cores with 6GB of GDDR5 memory.

I'm guessing $499.

I really don't want the starting cost to be above 400$. If it is. I'm not buying it for a while. Just like I did with the PS3, Might as well wait for the PS4 slim then.
