ATI Radeon HD 4000 Series discussion

[Chickenfeed]

Meh, if people were concerned about power consumption they wouldn't have bought the 2900xt, 8800ultra, 3870x2, 9800gx2 or gtx 280. People will deal with it for performance, its all about what your priorities are

This is what I've been saying all along.

You can't run your vehicle without fuel in the same way you can't operate a video card without power and sometimes to get the performance we want out of a vehicle, it just uses more fuel.

HD4870x2 only in end august ?!?!

I'll take 2 4870s with volt mods and waterblocks then please

That site is still basing that release point on pure speculation but it could very well be late August ( earliest I've heard is August 8th and that would be if things were going smoothly )

If you're gonna wait for the 1GB version wait until the 4870X2. But if it's CF on a card nope. ATI will never do a good driver for CF, at least in my life. So I wouldn't put too much faith in that

Crossfire drivers are nothing less then amazing. If you relized the type of obstacles that have to be worked around in Microsofts OS's then you would see that getting multiple GPU's to render at all is a spectacular feat. The catalyst developers are working full time between driver releases to find a succesfull way to get around one more obstacle and they have been succesfull at it many times thus improving crossfire performance. It will continue to improve on Vista where there main focus is.

to say "crossfire drivers suck", what is it being compared to? Look at how far and improved crossfire has become scents the X800 series.

Also as crossfire is becoming more and more mainstream game/software devs are increasingly suporting it. In point, I just dont see how crossfire could be a bad investment and I will most definetly be using crossfire with the 4870's.

ok sorry for the rant

G0ldBr1ck, you're 100% right. Don't misunderstand me, I highly appreciate the work of the engineers. But Crossfire is full of bugs, call it an inmature technology if you want. It's too much work to optimize for EACH game, like they have to do right now. You don't need to compare to anything, they're just bad. Or maybe a comparison with their own single cards is accurate. Only something like the 4870X2 could change this with its new interconnect. Being driver dependant = bad, always, period.

You got to watch out for these "private stuffs" You'd think you'd make an effort at literacy if your putting up a site like that.

If the 4870x2 is only going to run at the rumored 625hz on the core, I don't think any special bridge/interconnect will save it from 2 highly clock 4870s (which likely will hit 900-1000 with the right cooling )

As far as drivers go, I agree that both SLI and Crossfire are far from being perfect but you have to admit when it does work, it works really good. For the most part I've been happy with my 8800 SLI and can't say I ever regretted going for it and from what I've gathered ATI Vista drivers tend to perform better in relation to XP drivers than Nvidia's ( which at times I've felt I was missing something by running Vista )

4850 ordered from newegg ! Got the HIS one.Now just have to wait my aunt come to brazil bringin it

[Miwo]

ack this tidbit sucks. From Unwinder, author of Rivatuner..

Don't expect 48xx support earlier than in the end of July. I don't have a sample yet.

Not too be pessimistic, but it may be awhile till we can get past the CCC limit. The only other ray of hope is ATITool, which has not been updated in a long time to be frank. Here's to hoping AMD will release an internal clocking tool.....

700 wall is down.. broken, bashed, kicked in the nuttz. I have found a way to get past it. I have been testing for a few hours. I am hoping for a more elegant solution, but in the mean time it will do.

I will post up the info tonight. a seperate thread. WARNING: water cooling and V-mod is going to be needed. 700 is about the limit of both the stock cooler as well as the voltage given. it seems they set it about as low as it could go and be stable.

One more thing, that site is naming that card the 4870X2, but AMD has not even decided on a name so far for their R700.
@Chickenfeed: The fact that R700 has 2 cores running at 625MHz. might also the reason why AMD might give it another name. Maybe their R700 part will go through life as a 49x0, who knows....

EDIT:
@jimmyz: how much trouble did you have to go through to be able to get past the 700 MHz? Could it be 'easily' implemented in other software clocking programs?
Maybe you can now test what a 4850 is capable of when running at 4870 speeds, just to see what kind of impact the faster GDDR5 memory has. Although I don't think that's your main concern atm .

excellent, can't wait to see your results!
Please test the 4850 @ 750MHz if you have extra time in addition to whatever max you can hit, just because many people are interested in seeing how the 4850 and 4870 do with the same core speed and only differing in memory bandwidth

Thanks!

Some quick crossfire numbers on a P45 chipset, dual 4850's stock clocks

looks like ibuypower has put up some preliminary 4870 single + CF results:

only 40% scaling... well seems CF takes a bad hit on anything less then 2 pcie 16x slots.

Good thing i have my X38.

hmm, im quite disappointed by the scores in crysis. 1600x1200 4xaa only 24fps avarage.

singel 280gtx gets 26,4 fps @ 1920x1200 with 4xaa...

also im kinda confused, is this now 4870 in cf or 4850 in cf?

[zerazax]

Single GTX 280 gets 26.4 fps @ 1920 x 1200 with 4xAA on very high? Got a link? ... no AA I can believe but 4xAA seems a bit high for very high @ that res.

p.s. its a 50% scaling it looks like once you are no longer cpu bound

Nice pic

[zerazax]

I like the carbon fiber look lol

oh and iirc crysis wasn't scaling very well with the 4800's yet in CF so who knows what will happen

[Pudi]

halleluja

[informal]

^^ Above pic is actually a Phenom 9950(unreleased yet,soon to be) +790FX mobo+Hybrid CF of 2x4850s +2x4870. Can you imagine a system like that .

also:

1600x1200 4xaa -> 43fps

but since no further information is given what demo was used, its to hard to compare anything out there... even 280gtx reviews among each other.

[TheSynth]

What's with the ATI stickers? Are they manufacturing their own cards again? Or maybe they removed them.

[iTravis]

I'm still skeptical about the 1GB version, should I better off with the 512MB for better OC capability?

Yeah, I've seen # figure thrown everywhere so unless they were done on the exact same demo or were in game runs of the same setup, I have a hard time comparing #'s. Besides, in that neoseeker review, it doesn't even give what settings were used, because I doubt the 3870X2 gets even 30fps+ at very high dx10 1600x1200...
