This could be true but nahh i don't think so, it would be too expensive.Microsoft wouldn't pull a Sony(2006) on us.

They didn't even try to make this rumor believable.....

Remember when people were calling Nintendo crazy for having a whole billion of

just for the OS?

LOL

Whats funny is how everyone 5 minutes ago was saying 8 GB of GDDR5 on the PS4 is so awesome, etc etc. One rumor of 12 on the Xbox and all of a sudden it's overkill.

This rumor is most likely 90% false, and besides, in a few hours we'll get an official announcement anyways!

Personally, if I were Microsoft I would have done 4-8 Gigs of DDR3 + 2-4 Ggis of GDDR5 (much like a home PC build). DDR3 is very cheap and very fast (cheap being the key word).

The issue is not 12GB RAM but the split 8GB DDR3 + 4GB GDDR5 and the "IBM helping in the GPU development".

Hm, 8GB DDR3 + 4GB GDDR5 is not that unbelievable (though, not very likely cause of split pools IMO). On the other hand, 4.9TFLOPS GPU would mean 3072 shaders part @ rumored 800MHz (vs 1152 @800MHz in PS4) or maybe 2560 shaders @ 950MHz - that info is REALLY fishy, but let's wait few hours more...

i like it. make it happen MS.

wow 12gb? how much would that cost?

Well. 16Gb of the cheapest consumer grade DDR3 Ram retails for around $120 AUD. ($80 USD, give or take.)
Which to be honest, is bloody cheap compared to the $300 or so I spent on my System Ram.

However, that's DDR3, you can't exactly buy GDDR5 off the shelf and hence gauge prices, but even when said and done, AMD and nVidia have started to include 1-2Gb of GDDR 5 on some of the Lower end/Mid range cards now, so it can't be too cost prohibitive in the grand scheme of things.
