ATi 4870X2(R700) PCB Debut

[jVIDIA]

And noise ? Same as a 4870 ?

[annihilat0r]

Sampsa I BEG OF YOU, can you do a frame time benchmark in either Lost Planet or Call of Juarez and tell us if there's microstuttering?

I don't need FPS numbers I just want the sequential frame delay times compared to each other. You don't need to tell me "one delay is 10ms, the second is 50ms and the third is again 10ms" or something. Just tell us if there are significant problems of synchronisation

PLEASE!!!

[spoof]

Strange, mine sample is more just 15% faster than 4870 CF. Sampsa, share with me you driver, 'cause i think there is something wrong.

[w0mbat]

@spoof: Thats exactly what i think and why i asked him about his driver version.

+69, I concur even though you can't give us numbers, at least tell us if the micro-stuttering is fixed

So how hot is that chip in the middle? Looks like I can drop two MCW60 I have on it and save some money and not get a full block, maybe add a stick on HS to it? That card looks like its going to be a fire ball if its not on water.

[zerazax]

So july 14th is the now rumored NDA date on performance or what?

[cadaveca]

Previews on the 15th I heard. Driver is delaying launch.

[zerazax]

Good move I guess. Undercut GTX 280 sales without even having to launch a card and build up the hype train (and healthy markups for the profit margins )

I don't think GTX 280 prices were cut due to HD4870X2 but already cuz of HD4850 and HD4870 price/performance ratio eating up GTX260/280 sales otherwise. Of course HD4870X2 won't make matters better for NVIDIA either.

[zerazax]

That's my point - if the leaked numbers blow away the GTX280, no one will bother buying it without a further price drop since the rumoed $499 for the 4870X2 puts it at the same price bracket right now. And if those numbers look awesome, people will hold off on the 280 until the R700 hits the floors.

Which driver are u using? Do u have the gddr3 or gddr5 version?

so you have this card also ?

[Sampsa]

Which driver are u using? Do u have the gddr3 or gddr5 version?

GDDR5 and driver is sample_vista32-64_R700_8-52rcp2.exe

I've tested with 3DMark06, 3DMark Vantage (Performance & Extreme), Crysis, Assassin's Creed, Call of Duty 4, Bioshock, World in Conflict and Race Driver: GRID. I do my game tests playing the actual game and recording min, avg and max FPS with Fraps.

Sorry, I haven't tested Lost Planet or Call of Juarez, but haven't noticed any problems with the games I tested.

[ripken204]

please let us know about microstuttering

how about microsluttering ?

[adamsleath]

at least tell us if the micro-stuttering is fixed

they cant because it wont be

you'll have to pray for anti-micro-sluttering profiles or some strange set of tweaks depending on the game
probably.

micro-sl' is under nda

"i can assure consumers that all crossfire related bugs have been ironed out"
i saw this message on one of those sky banners attached to a flock of flying pigs - truely, would i try to mislead ?

[eric66]

they cant because it wont be

and how do you know ?

[adamsleath]

i dont; i just dont expect a fix. sli and cf has been around for ages and it's still flawed.
i'd like multigpu to work as much as anyone.
& i dont wanna be plagued by disappointing glitches with an already expensive card.
hopefully the games i want to play, play nicely with multigpu. what happens if they dont? tough toenails? buyer beware?
believe it or not i think multigpu is a great idea - if it works.
performance boost from existing gpu's, more sales for producers everybody wins - if it works well.

if some or most apps run perfectly well with xfire and other have problems then my logic says it's a programming problem related to specific apps. there's no helpful point in dismissing problems if they exist.

a list of apps that are non xfire compatible would be useful - perhaps "not compatible with multigpu" labelling

[Sampsa]

please let us know about microstuttering

I will try to test this tomorrow with Fraps, I guess it doesn't matter which game I use? I've never tried to measure this problem or used logging of Frametimes. Is there something special I should be aware of?

im not sure of any tests aside from using your eyes..

you can google, i came up with this:

[adamsleath]

If I notice microstuttering, can I minimize/eliminate it?
Yes. By running the game at a setting where your graphics cards are able to output more than the monitors refresh rate (that is, the maximum FPS the monitors are capible of; the pixels on your screen can only change so fast) microstuttering is eliminated completely. Most monitors have a refresh rate of 60 or 70Hz, meaning you would need 70 or 80 FPS to eliminate microstuttering

[jaredpace]

so you could just run your game of choice at ~65 FPS, constant (or relatively constant aside from some dips), and then set your display to 60hz.

not a problem unless your dying to have 1920 4xAA crysis veryhigh...

[Akabeth]

I still have no video card in my rig... T_T

Stuck with laptop. I'm not sure if I can hold much longer

[cegras]

LCD's don't refresh like that though. The hertz refresh rate is quite irrelevant.
