Developing a node for a memory technology is different from a node for general logic ... 

Compared to logic, NAND memory chips are more specialized and have a simpler structure, therefore they are easier to achieve density scaling ...

If memory chips doesn't do it for you, will a SoC do it?

That's probably manufactured on TSMC's 20nm process node so I don't think that proves anything about Samsung having their own 20nm process node ...

My God! You're never happy, are you?

Ok, what about Samsung stating that the Exynos chip is build on "Samsung's new 20nm process"

Alright, it looks like I was incorrect there but I still don't think AMD will be using Samsung since TSMC's 20nm process node likely has the higher yields ... 

does it really matter? This card alone cost more than the ps4, there are various other and cheaper pc graphicscards.

A10 7850K + R7250 in hybrid crossfire baby + 300 dollars left over for hookers...

While that is indeed a cool setup that many people overlook, it is fast becoming outdated, particularly with the increasing demands of newly released games and their sloppy optimization.

Really, if a person needs a gpu right now and doesn't have a ton of money to spend, I honestly can't think of better performance per dollar than the GTX 970. It gets roughly the same performance as an R9 290x reference, yet has a lower TDP and costs slightly cheaper, starting at around $330.

If you can wait and do have money, just wait for the R9 380X which will likely go head to head with the GTX 990.

Surprisingly PC Perspective last week reviewed launch drivers VS latest drivers for that APU + GPU setup.

As well as frame pacing:

If AMD can deliver 25% improvements with next gen of APU's combined with a low end card, and keep the price below $250 for mobo + APU + GPU, they pretty much have the specs for a kickass PC steambox with a sub $400 dollar price tag. 

@disolitude: Isn't the SteamOS based on Linux? And don't AMD Linux drivers suck? (Honest question here as I only know what I've read on forums).

@ofrm1: AMD's R9 290 is also a good choice: it's cheaper than a 970 and almost as fast, plus with a non reference card heat is not a problem if your case has good ariflow. Yes, it's more power hungry, but unless you plan to run it for +10 years during several hours a day, it will still be cheaper than a 970.
