Rumour: ATI Radeon HD 4890 X2 cards in the works

Rumours indicate that AMD's board partners could be introducing their own Radeon HD 4890 X2 cards (not a genuine photo).

Now that dual-GPU graphics cards are frequently topping the performance leagues, the first question that many people asked when the ATI Radeon HD 4890 surfaced was whether there would be an X2 version. Officially, AMD has so far declined to comment on it, and it’s likely that such a card would be difficult to manufacture when you consider that a single 4890 has a quoted TDP of 190W. However, reports have started appearing about potential Radeon HD 4890 X2 cards.

According to the rumour mill, there won’t be a reference Radeon HD 4890 X2 card from AMD, but it’s up to AMD’s board partners as to whether they want to manufacture such a card. Bright Side of News claims to have spoken to one anonymous board partner, which the site says plans to make a 4890 X2 card with two 1GHz GPUs and options for 2GB and 4GB of GDDR5 memory. The site doesn’t reveal the identity of the board partner, but says that it has seen some “engineering drawings” of the card.

The rumours also point to a recent video interview with AMD’s Saša Marinkovic from the guys at www.pcgameshardware.de. Bright Side of News says that Marinkovic makes a “we're going flat out to capture the crown statement”, while Softpedia says the video reveals that “AMD's AIB partners would be given the opportunity to make their own Radeon HD 4890X2,” adding that “the support for such a card is already available, thanks to an 8+6 power configuration that is featured on the current reference boards.”

However, after watching the video ourselves, we have to say that Marinkovic is much more guarded than the reports imply. He mentions that Radeon HD 4890 reference boards can feature two eight-pin power connectors so that board partners can make overclocked cards. Plus, when asked about the potential for a Radeon HD 4890 X2, Marinkovic says: “similar to when we launched the 4870, you could see the performance and the scaling by putting two of the cards in the system in a CrossFire mode. So, similar to that, if you take 4890 and run it in CrossFire mode it’s a great indication where the performance can get.”

Marinkovic doesn’t in fact say that board partners will be able to make Radeon HD 4890 X2 cards, but you could say that there’s an implication there. That is, if you put two Radeon HD 4890 cards in CrossFire mode, you can see how a future top-end card might perform.

There’s a lot of rumour and speculation here, and it’s also fair to say that a Radeon HD 4890 X2 card would need a lot of power, as well as a hefty cooler. Would you be interested in picking up a Radeon HD 4890 X2 card? Let us know your thoughts in the forums.

I'd like one with a Heatkiller waterblock on it.

And i'd like that to come out straight from a board-partner with warranty.

But hey, wishful thinking.

(Imagines a 4890x2 @ 1200mhz core clock and 1200mhz mem)

Respect for all X2 cards;) they are the best....

I'm waiting for DX11 X2 Card ;)

a card drawing 400 watts. two of them in crossfire: 800 watts. a nice mobo: 100watts a fun cpu: 120watts a few hard disks, bells and wissles: 80watts. 1100watts total. hefty system.
can't they come up with some supah performance low power design, more or less like core2 was for the PentiumIV?

Triple slot cooler anyone? Especially if the core is going to be running at 1GHz!
Quote Evildead666 15th April 2009, 17:50
No.
I'd rather go for dual cards if i was in for a setup like that.
Unless of course, the fantastic "link" between the two GPU's was finally solved, and they had unified memory between both cores...but thats probably for DX11 cards....

So if I put one of these things in my computer and turn it on will i be hearing from the FBI asking me if I had anything to do with the entire East Cost power grid got knocked offline?

Well, they've done the HD4870X2. It's only a small step from there to an HD4890X2.

Oh YES!!! I bought the ATI Radeon HD 4870x2 the day it was available and I havent seen a card (or cards) that could touch it, this might make me put it on ebay and get this new Monster.
Good thing I already have a 1300 watt PSU!!

lol,
S*D

Yikes, where are those numbers coming from? Bit-Tech's own numbers show an ENTIRE SYSTEM equipped with a single 4890 drawing less power at the wall than you're claiming for a single card.

I would think we wont see any 4890x2's until the die shrink, would shave off some watts.
Quote stonedsurd 16th April 2009, 01:58
I don't really think it's possible on either design (PCB sandwich or two GPUs on one PCB).
Too hot, too hungry.
Doubt they'd make enough money off of a move like this (whoever DOES it, that is).

There have a been a few dual GPU cards made already.

nonsense; rather invest the efforts in the new 40nm generation.
Ati was saying that it was "on track" and that it should make a debut in summer 2009. Summer is close and everything is quiet; rumors are floating that Nvidia (which was behind) will even catch up to Ati.
