Benchmarks for AT HD 5870

i'm kind of hoping the 5850 will surprise us, rumours are it will beat a gtx 285, and as stated in the other thread we might see improvements in performance once they've had a chance to get a few drivers out for them and resolve any initial issues that are bound to arise.

I think we can finally say that 5870 crossfire owns Crysis, about ****** time.

:confused: looks like crossfire gives very little extra in crysis

Single 5870

Dual 5870 in crossfire

I definately got higher fps with crossfire with my laptop, so I would say that drivers may well come into it. Impressive speed for a single card anyway! Price will be key here but looking good. The big difference without AA at 2560 also suggests something funky with engine or drivers, hard to tell without sys specs.

the second picture isn't the same res as the first, well the two AA shots aren't, they move up a slot and so are infact a decent wedge faster, but not massively.

the 5870 in crossfire is getting the same fps as a single 5870 with aa/af at a lower resolution, IE 5870 single gives the same performance at 1680x1050 4xaa/8af as the crossfire gives at 1920x1200 at 4xaa/8xaf, which as you'll know is a pretty massive bump in pixels and power needed.

However, judging by the single and crossfire numbers, its pretty much cpu limited around 55fps, and with aa/af the fancy drivers doing extra calculations to work out what needs doing on which core is killing a couple fps, so its only actually being tested at the highest res WITH 4xaa, everything below that is cpu limited.

You can see the scaling from the 2560 res, 35 single, 50.4 in crossfire, again with a little cpu limiting coming in but thats still a large performance increase.
 
I would imagine that the 5870 in cf is CPU limited - especially if they insisted on running it on an AMD CPU :D so in that situation you actually can see less performance even tho cf is working properly.
 
Well, if Crysis ran 43.6 frames SOLID, then that would be a good frame rate, as crysis (unlike some games) doesn't need much more than 30-35 frames to do the job IMO:)
 
I am happy with what the performance looks like at the minute and all these people disappointed because it doesn't kill a 295 i mean come on it's a single gpu using a hell of a lot less power and it isn't that far off the 295 even managing to beat it in a few games. Seriously some people really want the earth don't they lol :).

Single
1920x1200 4xAA 8xAF - 43.6

X-Fire
1920x1200 4xAA 8xAF - 53.9


An increase of 10 FPS, as this is Crysis I think that is a decent gain, if not amazing.

Not amazing but seemingly taking the framerate to the cpu limit, not the graphical limit, with an overclocked CPU that crossfire score may have increased up to 80fps for all we know. AFAIK more recent driver sets have drastically improved crossfire scaling (and sli probably) for Crysis, at launch the gains were almost non existant or even worse than single.

why they put the resolution higher for Crossfire? they should have used the same resolutions for single and 2 cards

Dunno, you can still see the relevant info, its always faster, and in the only really completely gpu limited area(2560x1600 on the single gpu) you see a massive increase with crossfire, well not massive but 50% isn't at all bad, again approaching the fps limit(it would seem) and a 5 fps range for cpu limit under various circumstances isn't uncommon. The drivers will work slightly differently and have more/less balancing to do depending on the complexity of the scene. What I read from those numbers is anything from 50-55fps could increase a lot when under a faster cpu, so really the only easy thing to read is crossfire is always faster and in at least one situation there is pretty decent scaling.

Not sure why you're using a review without either card in, which will be very old driver sets, also showing one of the games ATi tends to do very badly in(company of heroes) though again I think a recent driver set offered massive performance bumps to ATi when in DX10 mode(I think dx9 wasn't that bad on ATi but dx10 in company of heroes specifically had major issues for a long time).

http://www.bit-tech.net/hardware/graphics/2009/08/10/gainward-single-pcb-gtx-295-review/4

one of the more recent reviews, couple results where the 295gtx pulls away, but not by much, almost identical performance in more games than it pulls away in and several games where you literally wouldn't be able to tell which card you were using. They really are very very close in performance in most games, the odd massively Nvidia optimised game runs better but still not badly on ATi, and vice versa, theres some games that run great on ATi cards, but still not at all badly on Nvidia cards. Considering you'd be hard pushed to tell which card you had in your system, a 4870x2 at £240, or a 295GTX for the same performance at £330-350, the choice is easy for most people.

well in the resolution that i'm playing the 295 scored 10 wins and the 5870 only 3. i wont be upgrading my gpu for a while it seems.

the 5870 is still a good single card and a nice step up from the 48xx series but its nowhere close to a 8800gtx kind of thing.

If I already had a GTX295 or 4870X2, I wouldn't bother upgrading unless I desperately wanted DX11 or lower power consumption.

If I was buying a new card I would definitely go for the 5870.

I think it's the same situation people had when the GTX280 first came out, because it was similiar performance to a 9800GX2, with the 9800GX2 having a small lead most of the time, but this slowly changed as newer games came out, drivers matured and higher res/AA was used; i.e. the 9800GX2 quickly became obsolete compared to the GTX280.
