5870 1.6 x faster than 4870

[jigger]

You seem to sex up dual GPU's. How much is not 100% ? It could be 1%.

Scaling can be anything from hardly anything, to a lot. Dual GPU performance depending on many factors.

Again you cant compare a high end cards performance to that of two cards cobbled together because they are performance dependant on many different levels of support.

At 2048x with my 260GTX SLI I see as close to double the fps as makes no odds in prolly 15 out of every 20 games I've tried. Most of the rest manage above 60% scaling and only 2-3 games see gains below that or no gains at all...

As said previously if you play sim type games then you'd see a higher percentage of games not working with multi GPU so well.

Well a 4890 give's a 260 a very hard time. One half of the 295 performs close to a 260 and a £126 4890 on ATI favoured games will whoop a 260. alah loads faster in this circumstance. Hence me saying you cant compare the new ATI card to a 295 gtx as dual GPU cards performance cant relayed on.

The point is, high end dual cards, and high end single cards cant be directly compared.

I must have missed your first post, I see your point now . You cannot compare a dual-GPU card to a single GPU card without benchmarks. You can easily say "a 4890 will beat a 260", but you cannot say for sure, that a 295 will beat a 285, or vice versa.

 

[jigger]

And how much configuring did you have to do Rroff ? What was the perfomance like every other resolution and what effect did every level of AA/ AF have ?

I'm tired of this now. You and I both know dual GPU performance is all over the shop so lets stop ****** about.

 

[reflux]

Jigger, you really don't seem to have a clue what you're on about. What did dual gpu do to you to make you hate it so much? Answer my question - have you owned a dual gpu system?

No-one's disputing dual gpu isnt perfect, but people with experience in the situation think its worthwhile.

 

[Rroff]

I've run multi GPU rigs for a number of years and I know that generally they work very well...

Generally I don't have to do anything more than select enable SLI in the control panel and make sure I keep my profiles updated either via driver updates or between driver updates that nVidia are now doing for SLI.

No its not 100% perfect... but generally it works very very well these days... the only time I've had any major problems with it was back in the 6 series days... few times with the 7 series I've had to make my own profiles, but since then its been mostly smooth sailing.

For the record I've owned:

6800 SLI (didn't work very well), 7950GX2, 8800GT SLI, 8500GT SLI (for kicks), 260GTX SLI.

I wouldn't say from 7 series.. 9800GX2 is complete rubbish tbh

 

[Rroff]

I've never owned a 9800GX2 but my 8800GT SLI ran flawlessly... if it wasn't for the fact I changed to a higher res display I'd use it still.

In £ thats £199 and £299.

Did you pull those figures out of a dark crack?

When the 3800s and 4800s came out, they were $199 and $299.

People need to get over this 'rip off Britain' nonsense.

We pay the exchange rate equivalent + VAT.

That makes a 5850 £140 and a 5870 £210.

TBH I think your being a bit opptomisitic - launch prices are more likely to be closer to £199 and £300 with a drop to £150-160 and £260-280 once the dust settles... it'll prolly be awhile before they drop to the prices your quoting as theres little in the way of competition from nVidia.

EDIT: That said I'd be happy to see you prove right on this one

You need to calm down about dual GPU performance.

I've had a 3870X2, currently got 4850 crossfire, and I'm about to fit a second 2900 into my spare/server PC.

These issues you talk of are very rare, even when a game doesn't work, there are applications that can make a quick profile to force crossfire on.

Heard of Agent God's Crossfire Xtension application?

They do more good than they cause problems.

You're acting like you've tried a dual GPU setup and couldn't get it working due to your own incompetence so now you're raging against anyone when they say anything positive about them.

A lot of games have a doubling of performance with a second GPU, most games get a 70-80% boost on average. With each driver release and new game release, the scaling is going up and up.

Some games even scale close to 100% across 4 GPUs.

You might call it optimism, but were the 4800s not in line with what I'm saying?

I keep having to repeat to people, I'm not taking numbers out of the air.

The 3800s and 4800s were released at the same price points. The 5800s are supposed to be too.

So why would they be any different in price?

If you go and look at US prices on US stores, then convert it to £ using the current exchange rate, then plus VAT, you'll see the majority of prices are within 5% of eachother.

I hope it's better than at least a GTX285.

 

[LittleChimp]

But will it run crysis? .

Anyone who quotes Fudzilla as a source should be shot in the back of the head.

The reality is - NOBODY KNOWS!
Unless someone here has a 5870 card in their PC right at this moment, and produces some actual real world benchmarks, everything else is going to be wrong.

Liek teh 5870 r gunna b 2000000000% fasta dan teh GTX295 bcoz AMD ROOLS AND NVIDIA SUXORZ LOLLOLOL.

Yes, but only at 640 x 480.

I honestly don't understand why you would think it's not as good as a 285? A 4890 is on par with a GTX285, why would a 5850 be not faster?

Theres a bit of a sweeping generalisation... for instance there are atleast 2 people who regularly post on this forum who have inside access to ATI/AMD and another person who is (or was) a ATI beta tester...

I haven't had much experience with multi gpu's like some folk before me, but I can say that if I switch cat ai from advanced to off then the frames do most definitely drop, and this is in a number of games I've tinkered with.
