Nice to see an improvement in power consumption, its depressing that the same silicon could be many factors more powerful if they stopped with the clock speed/shader juggling

Nuts! Not long bought a gts250

Nice review, will be interesting to see what happens to 4850 prices too.

Interesting, the price on Ebuyer has already dropped from £83.05 to £79.99

Probably the reason for the temporarily dead link, great to see the same drivers used on each family of cards, the best graphics card reviews, now with a cherry on top!

No overclocking? or is that saved for a separate article?

Does the HD4770 really come with this cooler? From what I've read and seen elsewhere the cooling solution is more like this.

finally looks like my 8800gt has been well and truly bested at the low end, still it has lasted a long time. so are they killing the 4830 now since it has no point

Great review :) BTW Cross fire review planed for 4770 ?

Looks like a good card for the money!

I understand why you tested it using an i7 940 @ rediculus clocks, but it really isn't very representitive of the sort of system people are likely to be wanting to use this on. Is there any chance of some benches on mid-range hardware?

It was one thing we wanted to do, but ran out of time because we had to re-run our Far Cry 2 numbers a few times to be doubly sure that they were correct. There are a couple of retail cards in house already that'll be reviewed in traditional fashion and if there's time today, I'll pop down and see how well the reference card overclocks. I'll update in a blog post over the next day or so and add an addendum to the article. :)

That's Sapphire's aftermarket solution

Nice review - one correction

Regardless of that though, it’s double the amount of shader units in the Radeon HD 4670’s RV730 GPU and 25 percent fewer units than there are in the excellent RV770 chip, which featured 160 shader units or 800 stream processors.
640 is 20 per cent fewer than 800, not 25%.

Apparently then it's also HIS', PowerColor's, MSI's and
Gigabyte's "special" aftermarket cooler... :p

Haven't bothered looking up more manufacturers.

Thanks - fixed. /brainfart

My £104 4850 at Christmas still seems a bargin :D

Totally understandable! I think we are all dying to see just how well 40nm can be pushed :D

Muahahha someone got a cheap ODM deal :D

Very impressed with the performance for the price. Would have been interested in seeing how a 1GB card compared at the higher resolutions like 1920x1200, but I can go look at other reviews and piece it together myself. ;) (I only ask this because... well, Oblivion chews up a lot more than 512MB of graphics RAM when using some of the HQ texture mods. :D And yes, I still play Oblivion. The wealth of mods out there make it a whole new game.

AMD/ATi have pulled some fantastic technical achievements with RV770.

Maybe there will be a slightly underclocked single slot cooler model that doesn't require the 6-pin PCI-E for HTPCs? If it draws 80w max, that isn't much power draw to cut off...

Either that, or there's a special "reviewer's edition". The reason I asked in the first place was because I read about it over at ExPreview.com.

As of right now it seems impossible to get a HD4770 with the "reference" cooler. None of the manufacturers I've checked (and I checked a few more since last) have any HD4770 resembling the one tested at bit-tech and elsewhere. I'm not really liking this, to be honest...

XBitLabs claim it doesn't get near 80W at any given time. Seems like ATi put the connector there just to be on the safe side.
Paradigm Shifter 28th April 2009, 12:26 Quote
Fair enough - but I bet the card complains if you don't give it the PCI-E power line. :(

Seems like ATi want overclockers to be able to break 1GHz with this. :D

Stop looking for a conspiracy :P

ATI probably just relied on partners to send out their own cards and because competition is so tight quite a few seem to have got a good deal on this cooler.

Just be concerned with "reference" clock speeds - if ATI ships out pre-oc cards then that's a no-no.

I'm already bored with 40nm cards, I want 32nm parts now! :p

That's what they all say ...just before they come and get you! ;)

To be honest, I'm quite a bit interested in the cooling and noise properties since I plan to pick up a HD 4770 for a friend's birthday. He has a HTPC, but would like a bit of graphics power for the odd game as well. :)
