1. Games in PC alredy uses 4GB RAM today (it is System RAM and VRAM... not only the 2GB of the video card)... What make yo thing PCs will not use 8GB in games in 4-5 years... PS4 needs to live all these years without modifications.

2. The PS4 GPU is suppose to have close 100% efficiency of the raw power... PC have avg. 50% efficiency of the raw power... this close 2TFLOPS on PS4 will peeform like 3TFLOPS GPUs on PC.

3. Devs are not idiots... they asked for 8GB RAM... thd fact didn't use that today is because there is no graphical leap in PC since the first Crysis in 2007... now with PS4 the PC games will have again a big graphical leap in the next years.

4. I'm the only impressed in how AMD and Sony put a HD 7870 equivalent GPU into a APU with a 8-core CPU? An APU with low parts is easy to make but with high parts like that is really impressive... put a even bigger GPU could be near impossible in a business perspective.

Conclusion: 4GB was a big mistake from Sony... I'm glad they fixed that bootleneck early.

About the costs...

The biggest PS3 issue was the BluRay drive... over $300 alone at launch... the Cell was expensive but near $100.

The change from 4GB GDDR5 to 8GB will increase the cost from $50-70 to $100-140... not a big deal like the $300 of the Blu-Ray

You keep on talking without knowing what you talk about. AMD older cards had low efficiency due to the VLIW architecture. Nowadays both AMD and nVidia use high efficiency scalar architectures, so as always, you spread technical bullshit.

PS: It's funny how people use a number for the GDDR5 cost from a GAF user as it's the truth. Those modules weren't in production until recently, and AFAIK they haven't been used on any card, so we don't know/we can't try to guess how much do they cost. We can't know it unless we have a quotation from the manufacturer, and I doubt a guy working on a bank has it.

4GB is not enough in the long run, you'll be happy they went with 8GB in 3-4 years.

No. Had they gone with 6 GDDR5 and 2 DDR3 it would of been a better option... Or even a 4/4 split... but all that ram should be helpful especially as games move away from being pure gaming related.

8 was definitely a better choice over 4.

I never said it was a bad thing, but i just think 4gb of gddr5 is enough, especially if you get a much better gpu or even have the system drop in price by 50$. i personally owuld rather have a much better gpu, 4gb is of gddr5 is still better then 8gb of ddr3

That's highly debatable....GDDR5 is faster, but also has a much higher latency than DDR3. It's prefixed with "G" for a reason, because the high latency doesn't affect a highly parallel GPU as much, due to it's ability to process vast more amounts while it waits for a memory fetch. The CPU on the other hand, is an entirely different matter...

Console devs have been screaming for more ram for a long time now.
Im sure after the PS4 releases they will be screaming for Higher CPU clocks and improved GPU performance,

I think the decision to go with 8GB DDR5 ram will mean the console will have an extremely long lifetime, and it will mean this generation will be the longest console generation gamers have experienced.
Whether that is a good thing or not is something we will just have to wait and see.

Yeap... bullshit like there is no overhead in PC.

- Windows overhead
- Drivers overhead
- Graphic API overhead
- PCI-E overhead
- A lot more overhead

And before you said I'm saying bullshit... please do a research first because it is not my claiming... MS is saying the actual GPU have a 50% raw power efficiency, X360 had 60% efficiency and the Nextbox will have close 100% efficiency.

The eSRAM, Data Moves, and fixed units not existents in PC are created to archive that... the PS4 have 8 ACEs and 8 queues pipelines (GNC have 2 of each) to archive close 100% raw power efficiency too.

I'm no using random data or make assumptions... I was just sharing what the other companies says... not me... so call they bullshiters and not me.

The PS part... all the cost estimate was made using 32 chips of 2Gb GDDR5... the manufacturers share the cost of each chip... you can search in the google to find the official price of the 2Gb GDDR5 chips... for mass production contract Sony will pay less than the official price.

In any case no way close to the over $300 cost of Blu-ray drive.

The new AMD APUs uses the HSA for shared memory... there is no option for two types of memory.... Sony have trouble with separated memory pool with PS3 and a shared memory like the used in the APU give to developers more options and control over what they develop... but I have certain you know that.

Dear God I hope not, the 7th gen was so long it was agony, I wanted Wii U in 2011 and PS3/Nextbox last November.
