HD 4770 Previews/Reviews

[SKYMTL]

The missing hardware (mosfets, capacitors) will make 0 difference, unless you are running LN2 and you absolutely need to run 1.6v through the card

I agree but overclocking isn't the only thing that is being addressed here. A "dumbed down" voltage regulation section can lead to higher power consumption very easily. A good example of this is how Gigabyte has been able to increase efficiency on some of their GPUs by using their "Ultra Durable" approach. Them adding higher quality components (or in some cases just using additional caps and VRMs to clean up power distribution) has led to some pretty good results in power consumption tests.

I know that a point about that was already brought up but nearly every site seems to test power conumption differently so drawing parallels between two tests is very hard.

I think the lack of "uproar" over this developement is partly due to the way things happened.
Mainly, ATi didn't hold back reviews with retail cards.

Why people are not complaining about missing components on HD4870 cards? Or any other cards in general?
PCB's are designed to address wide spectrum of possible configurations. It is natural to have PCB which includes over the top PWM, output, memory sections.
I understand that AMD shouldn't sent fully fledged cards to reviewers while retail was getting standard boards. But both cards have identical specs. and perform the same.

I would just put the caps on myself....

Well, I've shown that this might not be that much of a drawback as you are suggesting. And also; the card is sold as is, the OC is just a bonus and a quite good one I would say.

About power consumption, most sites use a rather simple solution by measuring the power drawn from the outlet. You use it, Anandtech uses it and so on. The differences are in hardware choices but the GFX is still the same (one would hope at least :P).

I'm not complaining since I got a retail version. What I was saying that that people seem to react differently to ATI's flubs than they do to Nvidia's. It was more a comment about human nature rather than anything else.



Since people will soon be (and some are already) using RivaTuner which can clock the card FAR above 830Mhz, it could become an issue.

Thats because ATI fans are smarter than the nVidia ones

Don't shoot! Its just a joke

XFX First to Use Premium Reference Design for Radeon HD 4770

http://www.techpowerup.com/92862/XFX...n_HD_4770.html

any idea wen this one will be avail? thx...

I would assume about Mid-May.

I got bored and ended up buying a 55nm gtx260.. but i'll pick up a pair of these when the place i work at starts stocking them.. i have a feeling these will be more moddable than most other cards

My feeling is they would be LESS moddable than anything. And if you want to OC, make sure you get the higher end one, since it has more VRMs.

What happened to that TV show Pimp My Videocard?

Look at Xmods section !
We already have ASUS TOP BIOS which allows voltage regulation from Windows up to 1.3vGPU (review sample card up to 919MHz GPU on stock cooler)!
Also there are hardware volt-mods in the works, so it's not that bad as you think .

there's a non-premium one doing 1000mhz already right here: http://www.xtremesystems.org/forums/...d.php?t=223573

Woah crazy stuff right there. Hopefully the one i'm picking up will be as good. Strange though, is it only me or there doesn't seem to be many people picking this baby up?

Well it's that plus the fact that it's not as much fun to criticize AMD

Besides, someone posted a retail card doing 1GHz core. I don't think there is a noticeable difference between the cards.

[Wadkiller]

Will the stock heatsink backplate work with a aftermarket heatsink, specifically the Maze4? I'm not too keen to drill holes in the acrylic DD backplate. (The maze4 have the correct mounting holes for teh card, but not the back plate)

How thick are the bolts they use with the stock heatsink, wondering if the bolts of the maze4 will fit through the holes in the stock backplate.

Thanks

hd4770 clocked at 1 ghz video review :

http://forum.donanimhaber.com/m_31428998/tm.htm#

ps with new g_y cooler :p

[Caveman787]

wow thats impressive taken to 1000/4000 in that video it shows the 4770 trading blows with the 4870. I have a feeling if it were taken to 1000/4800 it would surpass the 4870 more often as the extreme high core clock is being held back by memory bandwidth.

These things in crossfire seem like they could be as good as 4870's when overclcked well.

HD4770 CrossFire is faster than HD4890 in some games

Onetreehill those are some good reviews but I actually meant as good as 4870 crossfire or close since well overclocked they get a pretty big performance boost.

I don't think this can be looked at in terms of practical use those.

The card had added volts, was artifacting at that speed and the fan was at 100%.

Most people already don't want to flash their bios, so doing all the above means that these type of results mean nothing to 99.9%percent of the general population.

HD4770 CrossFire Reviews

Today we are looking at how the new and exciting ATI Radeon HD 4770 performs when used in Crossfire mode. Priced at just $100 US, this affordable graphics card has already proved to be unbeatable in value, so now we will explore the feasibility of sticking two of them together...

http://www.legionhardware.com/document.php?id=828

After accompanying the launch of AMD's new mainstream RV740 GPU, and the Radeon HD 4770 part that it powers, with a look at HIS' offering based around said SKU, today we take a look at Sapphire's Radeon HD 4770 board, which features the exact same cooler and clock speeds as the aforementioned card.

Of course, basically repeating the exact same review all over again would be both dull and pointless, so for this article we've spiced things up a little by combining the power of two Radeon HD 4770 boards in a CrossFire multi-GPU configuration. Interestingly, in cost terms this brings a pair of Radeon HD 4770 parts into almost exactly the same price bracket as (if not cheaper than) a single Radeon HD 4890 1GB, which makes for a potentially interesting match-up in its own right.

So which is better - Two Radeon HD 4770 512MB boards in CrossFire, or a single Radeon HD 4890 1GB? There's only one way to find out...

ATI released the mid-range Radeon HD 4770 GPU to general acclaim last week. Based on a cheap-to-produce manufacturing process and high on performance, the <£80 card is a strong contender for best graphics solution under £100.

Its potency is such that you will be able to play most of the latest games on a 22in widescreen monitor, commonly shipping with a 1,680x1,050-pixel resolution. But what happens when you grab a couple of cards and set them to run multi-GPU CrossFireX? A £150-£160 outlay could well beat single-GPU cards at that price point. Should GeForce GTX 275 and Radeon HD 4890 be worried? There's only one way to find out, and that's by reading on.

HD 4770 is now @99.99 (89.99 after MIR)

[spursindonesia]

As the yield improves and GDDR5 price drops, the competition mantra in its class will be "How low can you go ?", LOL.
