We can speculate where the price of the HD4850 cards will end. It's already available for 149 euro at Alternate (Netherlands), including VAT. And Alternate is not even a price fighter.

Binning likely only plays a very small part in this. I am pretty sure I saw voltage numbers in one of the previews (but can't find it any longer
), and it was 1.089V under load. Compare this to the 1.22V and 1.32V of the HD3850/HD3870 (taken from some review - it's possible not all cards are exactly the same).Volt-modding might not really help too much though, not only would you possibly need another cooling solution, but the voltage regulator parts might get to their limits (or just blow up...).
edit: found the voltage number here: http://www.techpowerup.com/reviews/Powercolor/HD_4850/21.html - actually it's only 1.082V. Also explains the higher idle power draw compared to HD3850/HD3870 - for some reason idle voltage is almost the same, old cards were quite a bit lower (not to mention the frequency reduction is quite modest.

Dunno about VR-Zone, but at least one european shop has/had HD4870 1GB listed for presale @ 259€, so I'd imagine they won't be coming far behind 512MB models, more likely that they'll come out the same time

I highly doubt the 259€ bit however...
yeah.. it's probably lower. a 512mb product @199 and a 1GB @259?
4850 & Assassins creed dx10.1
"Only marketing" cit.
DX 10.1 which is not even supported by nV chips? How should that be possible?

I think he knows that NV chips run the DX10 codepath here while AMD cards use the DX10.1 codepath.
Presale prices are always bloated
Oh, and 199€ for 4870 512MB? I wish Finland was that cheap, I know 4850's are sub-150€ in Germany, but so far cheapest in Finland has been over 170€
Naturally it's 10.1 path for Radeons, 10 for GFsDX 10.1 which is not even supported by nV chips? How should that be possible?

No more ringbus + fixed performance (by way of lots more units while keeping transistor count fairly low) seems to indicate that the ringbus naysayers were right & the ringbus was a waste of transistors?
Do we know which bit of ATI/AMD designed the RV770?
Team A: R300 -> Xenos -> RV770?
Team B: R420 -> R520 -> R600

One characteristic of the RV670 and very possibly 770 is that voltage doesn't matter much relatively to clockspeed (I think the guys on XS concluded ths.
) for overall consumption. Which isn't vaguely close to ideals I know.It could be drivers that don't have aggressive Powerplay to scale clocks down.
The 8800GT SLI does look to offer the best graphics for price + it takes less power.
Nvidia should make a cheap bundle deal for them.

Last time I remember hearing from ATI design teams they had 3 teams which all collaborate more or less with each other
That only mentions 1GB HD4850 cards, and 512MB HD4870 cards.
