Of course AMD has to stick two 4870 GPUs on one board to win this prize. We ask if it offers any advantages over two single 4870s on a CrossFire motherboard. "The 4870X2 has 2G GDDR5 memory, which provides the end user a performance boost in high resolutions and high settings," says Byrne. "This is also a single slot board and doesn't require a CrossFire motherboard. It's just an awesome product and we're selling every board we produce.

"The great news is that demand keeps growing and we are significantly increasing our market share in both the channel and the OEM markets. The 4000 series graphics cards are considered by users and by customers as the best graphics cards available in the market today."

Byrne seemed pretty jubilant when we spoke to him just after the 4800 series launch. We ask him if his initial optimism has proven justified. "The great news is that demand keeps growing and we are significantly increasing our market share in both the channel and the OEM markets," says Byrne. "The 4000 series graphics cards are considered by users and by customers as the best graphics cards available in the market today."

The only way to stay ahead in the graphics market is to constantly innovate. To conclude we ask Byrne what we can expect to see next from AMD. Watch this space; you won't need to wait long for our next chat," he says. "Remember, the HD4870 X2 was step two, step three is imminent."

We would like to hear what the HEXUS.community thinks step three will be. Is it as predictable as the 4850 X2 or something else? What do you think a 4850 X2 card would bring to the table?

Step three???? What the ... ?

Step 3 could mean the activation of the sideport, which is currently disabled.

Excuse me for my noobness but ... sideport? What is it supposed to do?

may be X3, but I have no idea where they are going to put one more GPU :)))
so X3 is kinda out, but may be its was a plan to regain the market and step 3 will be good CPUs :))

Not two GPU's on one core, means that the actual GPU's could share data directly rather than having to send it through the on board crossfire bridge. It would increase the transfer rate of data immensely and then we would see the full potential of these cards.

Sideport is basically a connection between GPU cores (meh likes GPU technology). And this is why they didnt include it:

According to AMD the performance impact is negligible, while average frame rates don't see a gain every now and then you'll see a boost in minimum frame rates. There's also an issue where power consumption could go up enough that you'd run out of power on the two PCIe power connectors on the board. Board manufacturers also have to lay out the additional lanes on the graphics card connecting the two GPUs, which does increase board costs (although ever so slightly).

AMD decided that since there's relatively no performance increase yet there's an increase in power consumption and board costs that it would make more sense to leave the feature disabled.
Source - anandtech is kind of a adsite (read the p45/g45 preview) so I don't trust them that much, but it has the best info about r700 interconnection.

Sideport is just a peer-to-peer link between GPU (look at the 5GB orange arrows). But this is more of a short term thing. I don't think that's it in the grand scheme of things. If you notice, ATI (now AMD) does things in increments. The goal of the 4870 X2 (IMO) was to pave the way for true dual core GPU using shared memory buffer (among other technical aspects). I think (and I believe is rumored) that the R800 will do just that. Starting somewhere around Q1 of 2009. However, this is just my opinion on what step 3 maybe if you look at the grand scheme of things.

Hmm dunno, I would imagine that this would be almost a standard these days, IF it was achievable and the rewards were worth it.

If they're not, then I'd fail to see how simply enabling the port would be a 'step' forward for the X2.

R700 cards using insanely clocked (and stable) RV770 cores + sideport interconnect (?)

If we remember, AMD did claim in its slides before R700 launch that it would offer "a 100% increase in performance/watt over R680" , reviews of the card (in its current form) quashed that claim, but a company wouldn't lie on its internal company slide, it's not a PR event (unless the slide leak was staged) (?)

AMD/IBM was able to reach 22 nm silicon fabrication. Coupled with the possibility of a true dual core GPU with shared memory it isn't hard to believe that AMD maybe able to do some sort of GPU/CPU package. Technical aspects aside (as we wouldn't know how it would be done) this would be an innovation worth the attention of not only PC market but the console market and even wall street. But I digress time will tell.

Just asking....How possible does a dual-GPU card made of two G200(b) (192 SP / 448 bit mem bus GPUs) look like? Why did Byrne use the word 'imminent' ?

That's what I want to know. The GPU interconnect just may push this card into the WTF range of overkill. The interconnect basically doubles the gpu bandwidth of the fastest card to date. The outcome may be lackluster or it may pwn the sky, who knows. Any acclamation of a dual G200(b) or whatever is just going to be a barnburner, especially if they make it like the 9800GX2 - too big, too hot, & can't OC for nothing. I would rather them keep up the single powerful monsters. Let AMD have their X2s. On the other hand, let me have one too :D

What sideport does is eliminate the PCIe communication by doing it internally, correct?

If so, it should translate to a boost in performance, in theory, by eliminating an intermediary step (for lack of a better description), no?

Your 1st question is pretty vague for me and, doesn't appear to fit within the content of this thread. However, even Bryne admitted as much stating that such a card would be expensive. Also, if they do R&D GX2 for the 200 it would completely contradict their own belief of a single GPU being a better solution. Which IMO would eat at shareholders confidence when they said the very opposite.

As for your second question it's hard to say exactly what they have in mind. They are always innovating and developing something. If we don't see anything more from the RV770 I believe we would see some sort of innovation from the R800. We just have to wait and see. As it stands we know that the R700 has a sideport and it's inactive at this time. The real question will be if it was inactive as a strategic defensive against a GX2 variant or, they simply can't get it to bring an decent performance. Time will tell all...

Nvidia has done a GX2 for every major Arcitucture since the G70. A single chip is always the best option because you have less chance for conflicts to arise, that is the point Nvidia was making. But a dual G200b card would stomp the hell out of AMD

You would need 28 ram chips on that card...I dont think such a design would be cost effective.

You believe that a G200b GX2 would beat a X2. You can't burn the candle at both ins by saying:
-single GPU is better then a 2 GPUs
then turn around a say
-a G200b GX2 would stomp the hell out of AMD

That is the contradiction in and of itself regardless of whatever excuse is made. Their past GX2 variants have no baring on what they said recently regarding a single GPU solution.

From the way the diagram is set, it looks like the sideport will just allow the GPUs to communicate between themselves. That may or may not free up the bandwidth of the PCIe. It appears to be a logarithm thing where the parts out do the whole. The communication of the GPUs will speed up the AFR process but if the PCIe doesn't take that into account (& I don't see how the silly card would work w/o it doing so) then it would be all for naught. Those drivers better be kickass perfect. Adding the sideports to the equation is definitely going to make the drivers more complex by far from what we have now.

You believe that a G200b GX2 would beat a X2. You can't burn the candle at both ins by saying:
-single GPU is better then a 2 GPUs
then turn around a say
-a G200b GX2 would stomp the hell out of AMD

That is the contradiction in and of itself regardless of whatever excuse is made. Their past GX2 variants have no baring on what they said recently regarding a single GPU solution.

no its not for a very simple reason. A dual card setup is no faster than a single card setup unless you crank rez and AA/AF on it. For most users its not cost effective and also graphical glicths can occur suchs are tearing or pixelation from dual card, these issues do not affect single card as much if at all. In truth id rather have a single GPU card over a dual to avoid any issues that might arrise
