ATI Radeon HD 4000 Series discussion

Umm yeah. . R700

The black is pretty sweet looking.

When are the 4870 and 4870x2 supposed to be launched? From the 4850 reviews i'm seeing that the 4870x2 would beat the GTX 280 hands down, in every game.

[Star_Hunter]

4870 is out on the 25th of June while the 4870x2 is unknown but is looking like July/August

hehhehehe


I've been ithcing to get a replacement for my 8800 GTX. Now 2 4850's would fit the bill nicely and not cost a ton of money and I'd probably still be okay with my 500w Ennermax Liberty PSU.


On the other had getting two 4870's would probably just make me cream my pants


So the initial launch of the 4870's is going to be 512MB cards right? If so, I'll be waiting on the 1GB ones.

[Leeghoofd]

Their avatar and that post should give enough insight into their character

I'm so happy that ATI finally got their act together and I hope they sell laods of these cards... Gamers that will get these latest generation cards are spoiled as we get a good increase in performance at an affordable price level, but quotes like Bob's really turn me off big time... so silly, maybe it's me that shouldn't react at all and be smarter

Hope that 4870(X2) kicks butt too... I just got a good deal on the 280GTX (370 euro's) and will cherish that card like I did with my 8800GTX... and I don't need to turn up the heater anymore... it's an all in one package

[MomijiTMO]

Lol. Well I hope these sell like hotcakes but so far, 2 stores here have them for $299 . Oh well, I'll just wade the 'new card madness' and buy them in a month or two.

It's always a good day when the consumer walks away the winner

Hey why is there only 1 crossfire connector madoobie in the R700 pic?

[Hornet331]

Hey why is there only 1 crossfire connector madoobie in the R700 pic?

drivers right now only support a max of 4 gpus, and if this limit remains there is no sense to make more connectors.

[Macadamia]

Hey why is there only 1 crossfire connector madoobie in the R700 pic?

Because 1 connector = 2 cards, and they won't let you exceed 4 GPUs.

EDIT- LOL same reply in 1min :p

[v_rr]

Because you can only crossfire 2x HD 4870X2.
Otherwise you could have 8 GPUs rendering in 4x HD4870X2. 8 Tera-Flops

"2nd generation PCI Express bridge design", also known as PCI-e 2.0?

So it's confirmed that what they have done is changed the pci-e bridge to a pci-e 2.0 one?

[w0mbat]

No, they change a lot more, but u´ll see soon enough

R700 is way more than R680 was...

[MomijiTMO]

So you really only need to have 1 bridge on 2 4850s right? Why does everyone whack both on?

It thats true in august/september i sell the GTX280 i step-up to, but with PhysX driver for GTX280 the 4870X2 and 4870CF might not be so clear winner after all if ATI does not add the same thing to their cards.
But with the issues CF/SLI always has the increase has to be substantial to consider the multi-GPU X2:s/4870CF.

[Macadamia]

Actually, a LOT of Crossfire problems using Catalyst 8.3+ were exactly due to that.


Previously 2 bridges = 2 cards, now only 1 is needed since 8.3. And there was flickering. Everywhere. For those still with 2 on.


I guess this is solved now however.


It's been rumoured that the PhysX driver is useless for other PhysX stuff AS OF NOW, besides Vantage and UT3 mod.
But I can see Futuremark correcting the scale- this might get very lame.

[Xello]

No, they change a lot more, but u´ll see soon enough

So this August/September launch is FUD?

[MomijiTMO]

Ahh ok. Cheers.

[Macadamia]

It isn't FUD (8 weeks rumour is true), but the tech specs will ALL be exposed come June 25.

[G.Foyle]

yeah but that was my point , either you can stick a 2900 or 3870 with a 4850 or you wont ;/

Inintial testing met with no success. The 4850 would disable itself and the driver wont load. I'll try once more with newer drivers found on ASUS ftp (8.503 as opposed to 8.500 found on driver CD that came with the card).

[flopper]

No, they change a lot more, but u´ll see soon enough

R700 is way more than R680 was...

so they solved the bus communications and the scaling is then pretty decent?
I just hate that the decisionmaking what cards to get is not open with all info yet.

Anyone tried these yet? I would like to know what kind of performance gains is will give, if any....

[G.Foyle]

I tried and they give me black screen when windows login prompt should pop up. Catalysts 8.6 also dont work.
