HD 4770 Previews/Reviews

[Rasamaha]

would you mind telling us which program you used to bypass ATI's CCC overclocking limitations?

Just use a special verson of Riva Tuner, thank's to it's author.

pcgameshardware got 900MHz out of the "big" cooler, which kind of dents the theory that the cheaper cooler is better. Perhaps there's just a large variability in the amount of OC headroom in these chips? Would make sense seeing as these are the first chips on the new process.

Seems to be a good mid-end card.If it helps lower 4850 price even better....

From TPU:





damn

CFX doesn't make sense with these, it'd cost around $300, for that price 4870 CF is superior on all counts.

4770CF has good scaling as usual, but I'd never go cf with 512mb cards

they'll b down to around $70-80 within the blink of an eye.

$150 CF sollution... IMO that compares positively to the 512mb 4870...

[ToTTenTranz]

Why won't it support 3 and 4 way crossfire? It has two bridges..
Did someone try to do more than 2-way CF anyways?

How about a HD4770+HD4850 CF? Should be possible, right?

[Tuvok-LuR-]

we also have to consider that the retail samples miss a phase on the power side so oc tests on most review samples are not to be trusted

I'd rather spend the extra 50 $ for cf-proof equipment to pick a 4890.

[Shintai]

Seems a few reviews got good idle power consumption. The majority horrible. Wonder if its just a driverfix with powerplay.

But considering that review samples aint like retail is hmm hmm. Other cooler and different phase as mentioned above.

Need retail testers

If it is like in the xbitlabs one. Then I'll take one.

From Expreview regarding oc limit:

If you want more, just open the Rivatuner.cfg, find “RV770 = 9440h-9443h,944Ch”, and add the ID “94B3h” after.

Which reviews use retail cards?

I have never used crossfire/SLI before, will my E8500 @ 4.25GHz be fine with 4770's?

of course it will!
just ensure that you have a mobo with full speed 2xPci express lanes

The cooler is actually the same as some 4850 have − http://www.msi.com/index.php?func=pr...7&prod_no=1688

[STaRGaZeR]

Terrible idle consumption, GDDR5 strikes again... They should pack ATI Tray Tools with custom profiles with these cards :/

Not going to discuss "Coffey chat", like: I have a friend that know a friend that bought one FX 5200 instead of one HD 4870 because the number was bigger or bought 8600GT 1GB instead of GTX260 896Mb because it have more memory (both cases are real and the only thing they show is how ignorant or stupid humans can be). Not going to discuss also: I have a friend that know a friend that in his local store sell more "X" then "Y".

You should listen to yourself. It's ridiculous read those kind of posts here on XS. (same opinion about those posts in favor of Nvidia, intel, amd, microsoft, sony, watever)

I know quite a few well educated gamers that work in the "tech" field who still only buy nvidia based on misconceptions about ati drivers. These are software developers and server admins btw, and they still have no clue because they aren't what I'd consider "enthusiasts".

The points is not to say that every consumer feels one way or another but to share feedback from based on your experiences and conversations with others. The consumer bias favoring nvidia does exist whether you want to admit it or not. Have you ever heard someone who isn't an enthusiast say they only buy ati?

You greedy bit-tech guys, just can't say no to Nvidia's money, can't you?
GTS250 anywhere to 50%-100% faster than 9800GT according to them

Extremely nice catch!

Time to post that in their forums and stir a ruckus?
