ATI Radeon HD 4000 Series discussion

Rage3d architecture review: http://www.rage3d.com/reviews/video/.../architecture/

Wow, looking at how ATi basically modified or updated nearly EVERY component of R600 as well as the basic organization of RV770, calling it just a refresh is a disservice... amazing

I wouldn't call it beat, since it's less than 5% difference. But still, a $300 card matching a $400 card's performance, now that's great value.

Agreed, they scaled PAST 100% in COD4 and the Witcher (assuming the only reason it was able to pass 100% is the 512mb of vram bottleneck).

I want to see 4850+4870 Xfire numbers :up:

Ebuyer £179

It will end up being £149 for the lookout.:)

Edit : Free Delivery as it accounts.

Metroid.

just phoned ocuk and this girl answered, i asked her if they could knock some money off my purchase as they are selling their 4870's bundle at around £100 dearer than Ebuyer...
she said 'noooo sorry' so i said that you would lose future custom and she said 'well ebuyer IS our company so we wont lose customers'...

so they price gouge at ocuk and make their offer at Ebuyer look outstanding.... the ebuyer offer doesnt have them in stock...... :banana::banana::banana::banana::banana::banana:s. ...

End of Rant

Who cares dude. It's only money and you got them first. Enjoy'em :)

and i can send em back (when i've had my fun....):up:

German lowest price so far:

216,46 € ( but not on stock )

http://geizhals.at/deutschland/a346315.html

In a few weeks price might settle around 200 €

I'd be temped to get a pair of 4870's over a pair of 4850's, but to be honest, i'd need a new PSU :(

just snapped 1 up @ ebuyer very good for the price ...order b4 8pm it says to recieve it tommorrow ....we'll see...... kai is that bristol in the backgound of ur pic ?...soz ot..:cool:

No - the centrepoint building in London, at the crossroads of TCR, Charing Cross Road and Oxford St.

TCR is Geek Mecca :D

I live in Axbridge though....well, until the end of July :)

4870 is out in newegg but a10 bucks more than bestbuy

just orderd 3 4870's. damn its gonna be hard to get any money back out of my 2 month old 3870x2's and 3870's, with the 4000 series so cheap no one is gonna want them!!

600 dollars worth of cards owning 1300 dollars worth of cards.... priceless

That can't be right. Crossfire 4870's score over twice as high as a single 4870???? That would mean the scaling is better than perfect.

heh, all 3 brands are sold out on newegg now!

Must have got mine in the nick of time!

Nope.The drivers are in beta faze and not fully optimized for HD4xx in ssingle card mode.Expect even better performance once AMD starts to fully optimize for the new uarchitecture.
So single card performance is not up the max possible.In multi-gpu scenario,2 cards are performing great due to present good optimizations in Catalysts for CF.

Hehe, "faze". :)

That doesn't even make sense. Dual performance is based on the performance of a single card. In what reviews have you ever seen two cards perform over twice as well as the single card? I've looked at hundreds of reviews and I've never seen scaling that was better than perfect.

It might be because that particular game is very multi GPU friendly, and that the new ATI cards handle TLP/ILP.

I don't know if that would lead to better than perfect performance, but who knows maybe it's just THAT efficient in this particular instance?
