40nm??! why not a smaller fabrication?

Because TSMC canceled their 32nm bulk process. 28nm isn't yet ready for volume production, so they had to fall back on 40nm (which at least has most of the teething problems we saw with 58xx and Fermi worked out now).

when the latest nVidia cards came out there was a forum full of excitement and anticipation. now it's ATI's turn. so next year when nVidia drops the next line... Although the nVidia Fermi cards have been crucified in some reviews.

 

[rohitbaran]

nVidia would be pissing its pants now!

 

[verbalizer]

ooops. what is nVidia going to do.? and I'm more of a nVidia guy than ATI.
ATI gets props.

 

[Trialsking]

Competition rulz! Lower the prices on the 5870 so I can Xfire already

love the avatar bro..

[citation][nom]Anon_Y[/nom]I just hope AMD fixes all their driver problems, then they'd be unstoppable.[/citation]

I had a Radeon 4850 for two years, then a GTX460 since this summer. They both have "driver problems". At least AMD releases new Catalyst drivers every month, so you know when you can expect a fix for the issue. With Nvidia, the schedule is much more sporadic and unpredictable. Sometimes many months might pass between updates, and then all you get is a Beta driver.

Really because I've had a cursor issue for well over a year. Just because they release a driver every month doesn't mean they actually fixing all the previous bugs.

[citation][nom]LORD_ORION[/nom]Seriously look, the 6770 has 184GB/s of memory bandwidth for its relative texture fill.[/citation]
I believe it's 134GB/s. Despite the fact that it's difficult to read off the chart, 184GB/s wouldn't make much sense given the 6770's memory clock, just 50MHz higher then the 6750 at 1050MHz. Given the high bandwidth in relation to the memory clock, I'm assuming that both of the new cards use a 256-bit interface.

do you have dual monitors and when watching a full screen video one one of them, after a short time your mouse will distort
and then it will effect your whole screen and the only way (if you don't catch it when it starts) is to reboot.
is this similar to your issue.?
if so then call me mal-stadamus.. lol (Nostradamus)

 

[hixbot]

Is it just me, or do we not expect the 6700 series to be faster than the 5800 series? Looking at the charts, it appears to be on par at best.
I would expect a 6770 to be faster than a 5870, and the 6870 to absolutely kill the 5870. Looking at this chart, it doesn't like such a big leap forward.

 

[elcentral]

hehe goint to start saving some money for radeons next 2x card to replace my 295 but it will still hold out for 1 more year ^^

No, it's expected that the 6700 series is faster than the 5700 series and that the 6800 series is faster than the 5800 series.

Was the GTX 480 twice faster than the GTX 285?

 

[hannibal]

Well 68xx series is not so easy task. It was supose to come in 32nm, but now they have to stay in 40 nm, so 68xx series most propably is not so much better than 67xx series. Ofcource there is more compute power, but when you compare the power consumption between 5770 and 6770, and if the difference between 5870 and 6870 would be relative to this, it means that 6870 would be the hottest ATI/AMD GPU for a long time. It can be problem, but who knows. One posibility is that only middle range gets this upgrade and upper end waits until 28nm production starts... Or they have to use less agressive GPU speed in upper end, untill they can make the production node leap. (or use more expensive cooler...)
6xxx series was suposed to be made in 32nm production technology, so every "upgrade" card has higher wattage use than they were hoping.

All in all this 67XX series seems to be really good upgrade, but ofcource real world and synthetic results are not the same. But this seems to indicate guite good real world increase allso. Maybe not double to 5770, but even 50% more speed would be guite impressive considerin the change in manufacturing node.

 

[hannibal]

Hmmm The power usage difference seems to be 35% between 5770 and 6770. Can some one who know better tell, how much less 32nm production would use power than 40nm (in theory?)

[citation][nom]rottingsheep[/nom]apparently leaked by AMD to hold off people from buying nvidia's cheap fermis[/citation]

You mean Thermi's? What about nvidia's leak about "mid life kickers", "Kepler" and all that powerpoint BS 😀. Of course AMD "leak" stuff when the launch is in less than few months. You forgot how many months sites were hyping Fermi and how dam good it would be? I think it was half a year.

yes its lower, but when you have more processors and so more transistors, you'll consume more power.
35% more power but for 2 times more ROPs, stream processors and texture units!!! a good ratio...

when you compare the 5850 and 6750 which both offers the same number of processors, its 25% less power usage.

but the chart says "40nm" for all the GPUs (not 32), so not sure if its a mistake here or not.

Your expectations are foolish. It will be impressive if they can get more than 20% gains using the same 40nm TSMC process the current generation is using and keeping the costs in control.

Maybe it was a good idea to wait with the new Intel processors.

ATI: We present to you! HD4870X2! I mean HD6770!

 

[Onus]

I'm looking for more graphics power with the same or LESS electric power; perhaps the 6670 will have the muscle of the 5770 and the appetite of the 5670...

 

[mosu]

20% is the commercial ratio of upgrade between generations.Why should they give you 100% more performance for the same money?You should consider all other improvements and capabilities alongside with the reduction of power consumption.Imagine two 6770 slightly underclocked in a laptop with 4 teraflops of graphic power and complete yourself the AMD naming scheme.Then add pricing and compare with NVidia prices against performance overall.

 

[hixbot]

Vladislaus I said nothing about twice faster. Merely faster, a 6770 than the 5870.

The 5770 is faster than the 4870. The 4770 was faster than the 3870. So why is it wrong to expect a 6770 to be faster than the 5870?

Before the market got so stale, generations leaped forward by much more than 20%.

scrumworks, 20% somehow equals twice the horsepower? my expectations aren't the issue. The chart title claims twice the horsepower.
