AMD's 28nm graphics is only a die shrink

Written by Fuad Abazovic

No new architecture
If you though that after dual-chip cards the rest of 2011 will get very boring for the graphics world, you got it right. After Radeon HD 6990 and GTX 590 we can only wait for 28nm chips and hope that they will make a real difference. Turks and Caicos will barely excite anyone as the Llano APU will have graphics that will put a lot of pressure on mainstream market. Brazos will compete with entry level.

According to our sources, AMD's Southern Islands are nothing more than a die shrink of an existing 40nm Northern Islands. There won't be any major architectural difference, just a die shrink. However, you can expect to see some more shaders, as at 28nm there is simply more space and the TDP's are lower. This still means that the chips that will replace the HD 6870 and HD 6850 will get more shaders and performance.

The new graphics architecture from AMD will only come in 2012, when the 28nm process gets more mature, and most likely this will happen only in second half of the year. Whether you like it or not, you will have to start getting excited about integrated graphics as from this point there will be more and more graphics on CPUs.

Perhaps they have learned from the problems that you've outlined in the Llano article on yields......they may be going to apply a "tick tock" cadence to both graphics and cpu design in future?

One thing though, I guess that going from a 40nm to a 28nm process is a big jump and will mean a larger increase in the number of shaders they can put in there. They don't really need to develop a new architecture in order to deliver a large performance jump.

Hey!!! I have a year before I am owning yesterday's junk technology! :lol:

techno, my thoughts exactly. Because its AMD Fuad has put a very negative spin on this article but equally he could have said due to 28nm we will see 6990 performance in one single die and lower TDPs than current 6970!

I think Fuad is upset that AMD will have 28nm so much earlier than his beloved nVidia and lets fancy it if anyone has problems with TDPs its nVidia!

Quoting loadwick:
BS BS BS BS BS..i admit-im talking BS!!

LOL - you amd fangirls really like talk BS is it?
Why you coming here if you see everything through red tinted glasses?
Have to laugh really hard when idiots like you claiming Fuad loves NV more than amd LOL
Oh,problems with TDP - when was last time you checked what temperatures on 6970 and 6950 and what on 580,570,560? You sound to optimistic for amd fanboy LOL

I hope for the scenario where fuad sources are wrong about this, and that happens often on this site.

Its because NV cooling is better, the chip itself produces more heat.

OT: Well, a die shrink should help with performance already. NV showed that architecture change is a risky thing, pretty good.

The article is close but not correct. The new chips will be VLIW4. There will also be some minor improvements. The article states more shaders buts it should have said different shaders.

Actually, now that I look at it again, the article is not that accurate.

This could have been a great article should the right person was writting...

I'm not sure the author understands what a "die shrink" is. Any architectural changes, such as the addition of more shaders as he mentions means that it won’t be "only a die shrink."

Obviously Fudzilla not getting many hits this week so they got Fraud Abazovic to create a nice fud article..

The new 28nm AMD and Nvidia cards will be a major jump in performance and more importantly lower power use. Nvidia predict almost 3 times the performance of current tech with there new Kepler GPU. AMD will offer similar peformance but better price and lower power use, just like with every other Generation. Imagine AMD will add nearly double the shaders on top end cards and increase clocks, these cards will be beasts..
