Right. I meant to say it will beat both memory bandwidth wise. 

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)

Honestly I don't buy your GPU side of the APU is less powerful so there is no need for faster RAM.

Past AMD APUs have (pretty much) all had proformance benifits from faster RAM (specifically A8/A10). There is no reason to think these newer generation ones will be any different. As I said in my first post this is still a wait and see topic because we have yet to gut either of these consoles.

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.

That's because AMD APU's before didn't work like this:

The Xbone is bundled with Kinect do you noticed this?

Time to educate: 

1) GDDR5 uses less energy and produces less heat.  The DDR3 is not "better system RAM."  Yes due to lower speeds it has tighter timings, but speed matters much more.  Example: My 2133 MHz DDR3 has 50% less tight timings than my old 1600MHz RAM, but it still performs better at EVERYTHING.

2) The 7750 has 512 Cores and runs at 900 MHz compared to the X1's 800 MHz.  Before RAM is considered it should be about 30% weaker.  Most 7750's use GDDR5, but there are cheap versions that use DDR3.  The DDR3 version performs half as well.  

RAM feeds the core, and the faster it is -> the faster the core can process.  Even with a miniscule amount of SRAM, the system will be majorly bottlenecked.  Prepare for a lot of pop in!

READ THE F*CKJING DATA SHEETS. gddr5 memory takes LESS heat than the ddr3/esram combo. The quote is SIMPLY WRONG because that idiot was too lazy to actually read the data sheets.

READ THE F*CKING DATA SHEETS for god's sake. How many times and how many people have to tell you that?

The cost thing was true upto this time, since gddr5 chips were not used on larger scale up to now. Sony wants to sell >10 million PS4 per year, that alone is >160 million gddr5 chips. >160 million chips for Sony alone. (That is more than ten times the number of cell chips Sony ever ordered in any year).

You should stop trying folks information outside this anandtech article is clearly not relevant to the poster. Everything on the internet is wrong except anandtech and there assumptions.

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 :)
