I tend to agree with you, however I'm going to reserve judgment until they actually release the card. Two of the rumored new features sound like they will make a huge improvement. The GPU-to-GPU communication will be done in memory, plus the entire memory on the card will be fully utilized (as opposed to 'half wasted').

If you look at how seemlessly multiple CPUs can chug through an SMP-enabled application such as video encoding, you've gotta keep the faith that someday dual GPUs will be capable of 100% gains over a single one.

If the X2 can beat the GTX280 without any major driver issues, AMD will have pulled a major rabbit out of their hats IMO. I personally see the lack of texturing units as the 'achille's heel' of the 4870, but time will tell.

Your first point assumes the current bridges are a limiting factor for communication between GPUs for CF and SLi- which I've never seen referenced anywhere. Link to this needing a change?

it's not going to be faster than 280 gtx if it's $150 cheaper...that's just a hunch...😉

According to OBR (who definitely has a GTX 280) HD 4850's in CF are faster than a single GTX 280.... in whatever benchmark he tested (probably Crysis). And he's no AMD fanboy either.

If HD 4850 CF is faster.... HD 4870 CF should definitely be faster as well.

Radeon HD 4870X2 faster than GTX 280, no microstuttering?
Written by Andreas G 07 June 2008 19:39

Radeon HD 4870X2 is the high-end part of the Radeon HD 4000 series. Like the Radeon HD 3870X2 it sports two linked GPUs on a single PCB. The exact nature of the link is unknown, but we've been told that AMD has done some major changes to the linking since the last generation, since AMD was quite displeased with the performance of the 3870X2 bridge chip. According to a recent post at VR-Zone, citing a source who does not want to be named by name, Radeon HD 4870 will not suffer from microstuttering since the communication will be done through the memory instead of a bridge chip. This should also have a positive effect on the CrossFireX performance.

Microstuttering is a result from using AFR (Alternate Frame Rendering). The frames are then sent to the monitor at an uneven rate (more like two and two instead of a steady flow) which causes stuttering. Running two Radeon HD 4870X2 in CrossFireX for three or four GPUs should still have the same rendering problems though, I.e. if AMD hasn't come with another new feature for the Radeon HD 4000 series, but we're skeptical there.

There will also be Radeon HD 4850X2 cards which will instead use GDDR3 memory and lower clocks overall, but this is an optional card for partners. The performance of this card will of course vary depending on the clocks, but it should still be in the high-end part and able to compete with the GeForce GTX series, while the 4870X2 and its GDDR5 memory is estimated to beat the GTX cards with a margin. Both cards are slated for a fall launch.

4850's in Crossfire.... not a single 4850.

I doubt ORB is lying and it is not that hard to believe either. 4850 CF should be faster than a 9800GX2 and in certain situations the GTX 280 might not be much faster than the GX2.... I think 280 will excel in high res + AA/AF where the GX2's 512MB framebuffer wasn't enough. But in normal situations.... I don't think the 280 will be that much faster.

Ok thats much more likely...not saying it will or wont, but I thought you were saying a single 4850 would beat it lol.

No offense intended, but an unsubstantiated rumor from a "source who does not wish to be named" is not information anyone can take seriously.

I hope you're right though, the people who desire dual gpu card that are sensitive to "microstutter" would benefit by this.

I don't think it changes a lot for most people though. SLi/CF have been around for years, reviewed literally hundreds of times.

The "microstutter" hasn't been a big deal in any of those reviews, nor pointed out by users on forums till this year.

The GTX280 will still have advantages over dual gpu solutions (including 9800GX2) whether they microstutter or not.

Fair enough, it's a rumor but more of them are coming out and NV fan boys are getting more and more worried that AMD/ATI is heading in the right direction and NV is going to be behind.

Not sure if that has been posted yet. Picture of Gainwards box. On the bottom in fine print says it requires a 550+ watt PSU to power the GTX 280.

Maybe AMD is on the right track. That said, its looking like the GTX 280 is going to be about double the performance of the 9800 GX2, at least in demanding situations. I don't see AMD topping this type of performance by leaps and bounds with CF solutions when they were already behind. If a pair of 4850's can consistently beat a GTX 280, that would be the greates technical achievement ever by ATI. The performane/price ratio would be at a whole new level.

actually i think AMD is heading in the wrong direction... But they are doing it on purpose to reach fusion, which will be the ultimate mid-range.
But for high end they are totally missing the mark.

I like the claim, "Your games in living color". It would kinda suck if the GTX 280 only put out a monochrome signal.

I really don't think that is true in the end. Some people might not like the idea of a dual-GPU card, but from the reports that HD 4850 CF beats a GTX 280, I'm pretty sure at this point that people concerned about raw performance will be buying the 4870 X2.

more like dual GTX 280's...

edit: plus, the reports that 4850 CF beats a single GTX 280 are still far from verified. ATI would have to make some pretty big strides in a short amount of time, considering that their last dual card just edged out the 8800GTX which was over a year old at the time of the 3870X2's release.

 

[sagrada]

Dual GTX280's wont happen without built in water blocks. Considering the G80 didn't have a GX2 edition until the G92 at 65nm and the GT200 is actually a larger hotter core than G80, we won't see anything until GT200 is shrunk to 45nm or 40 nm at the least.

According to OBR (who definitely has a GTX 280) HD 4850's in CF are faster than a single GTX 280.... in whatever benchmark he tested (probably Crysis). And he's no AMD fanboy either.

If HD 4850 CF is faster.... HD 4870 CF should definitely be faster as well.

Ok now I really believe the GTX 280 is close. This is normal for a nvidia launch - dampen expectations. You can bet on release day with new discovered drivers, the GTX will not disapoint.

I don't know what people expected from the GTX 280, but it looks like it delivers - 37 FPS in Crysis @ 1920x1200 VH, meanwhile 9800GX2 gets ~31. It's a solid 2x faster than the 8800 Ultra. The specifications support that performance, and I don't think there will be any magic drivers.

The problem this time is AMD is actually competing. The HD 4850 & HD 4870 are serious contenders, and they are very cheap to manufacture.

edit: plus, the reports that 4850 CF beats a single GTX 280 are still far from verified. ATI would have to make some pretty big strides in a short amount of time, considering that their last dual card just edged out the 8800GTX which was over a year old at the time of the 3870X2's release.

if two 4850s (200$ each) are really faster than a GTX 280 (650$) ten AMD will raise their price, a lot. Probably to around 400$ per card.

Plus I smell bull, there is no way that claim is true.

I just don't see 4850 CF being faster than a single 280gtx powerful card for Crysis.

Dual GTX280's wont happen without built in water blocks. Considering the G80 didn't have a GX2 edition until the G92 at 65nm and the GT200 is actually a larger hotter core than G80, we won't see anything until GT200 is shrunk to 45nm or 40 nm at the least.

I wouldn't bet the rent on that. 😉

Thermal constraints mean a GT200-GX2 on 65nm is impossible. Not only that, but imagine the PCB needed to accomodate 2x 576mm^2 chips with huge IHS. Not only that, but nVidia would have to use GDDR5 memory as it would be impossible to have 2x 512-bit bus for the 2 GPUs. And the thing would have to cost about $800-900 for it to be profitable.

55nm GT200 would still be above 400mm^2, so I highly doubt we would see a GX2 card from that. If we did, the clocks would have to be so low it wouldn't be worth it.

i think we may actually get a 55nm GT200 GX2 around dec08-jan09. Who knows by then 6 way sli may work... hehehe. $5000 on graphics cards for crysis at 51 FPS! YESH!

Actually I was only replying to "dual GTX 280s", not a GX2 type solution. Chewietobacco kind of strayed from nitro's point that dual/triple GTX 280s will be the high end solution, not dual/quad 48anything based on what we've seen so far.
