Understanding why Xbox One doesn't need GDDR5 RAM

My OP is fine and correct, but its ok.

Just a few minutes ago, I wrote a lengthy post explaining some of the wrong assumptions you make. Pretty much every other point you made in your post is also false.

If you want to learn why the gddr5 memory in the PS4 produces LESS heat than the ddr3/esram, and why designing a mb with gddr5 ram is easier (and hence probably cheaper) than one with ddr3, I suggest you download the data sheets from hynix/samsung and read through them. I don't hink I should waste my time writing another article explainig it to you because you seem to simply ignore what people write if it doesn't repeat what you _think_ you know (and yes, I am right and you are wrong)

Same reply as ethomaz:

"There are merits to both approaches. Sony has the most present-day-GPU-centric approach to its memory subsystem: give the GPU a wide and fast GDDR5 interface and call it a day. It’s well understood and simple to manage. The downsides? High speed GDDR5 isn’t the most power efficient, and Sony is now married to a more costly memory technology for the life of the PlayStation 4."

Feel free to post some more personal opinions and theories though.

I don't feel educated enough in this stuff to shoot any argument down about the speed of memory and bandwidth (you bloody geeks ;) 

*BUT* a few things that don't sit right with me....

I don't think i have actually seen *any* developer say that the Xbox is a powerful machine... the only comments ive seen is that the Cloud is something that could be useful (and we know all about that).

The bit thats bolded (that i didnt bold but you did)... is false with *ANY* tech that starts to get used more (and GDDR5 if being used more and more now)... the cheaper it gets... so it wont stay costly. That makes me discount that argument straight away.. because if they cannot get that right, then the rest of their argument is surely up for mis-information.

Finally.... we only have spec's for the PS4... Xbox have not released any specs except for 5 billion transistors. There are only two reasons for not releasing specs:

1. They are changing the specs (very very unlikely)

2. The machine isnt as powerful.

That is all :)
