That's the max DPM state, which the card stays in very easily and constantly due to water cooling removing temp-related throttling issues which 290/290X had. Main goal of this card is to be faster than the equivalent CF/SLI setup.

This might be a better deal than dual cards as cooling will be MUCH MUCH easier. If you have an AIO for the CPU as well you can keep it cool very easily.

780ti SLI is still faster,
It was when you go above 2 cards, AMD's superior xdma runs away with the crown.

Are you sure?

I didn't take much time in google, but 290x crossfire seems to be substantially faster than 780ti SLi. With the added benefit of you being able to add a 3rd card for only a little more money than 780ti SLi if you catch the right prices. I'm not sure if the 780ti prices have come down so that could have changed. It's out of my price range so I haven't looked.

Rather than either 290x or 780ti, I would go 3 way crossfire 290's. That would absolutely scream.

That looks really shady.

I can't think of a single dual-GPU card that's EVER been faster than a quality CF/SLI setup of contemporary cards :

Eg : Radeon 6990 was slower than CF 6970OC, GTX690 was slower than 2X 680OC cards, etc.

Dual-GPU cards honestly suck, unless you :

Have a SFF case or a single PCIe slot to work with

or

Have a need for quad-GPU and only two PCIe slots to work with

For everyone else, they're MUCH better off with separate cards. If anyone told you they'd rather than a 295 in comparison to a quality 290X aftermarket CF rig, they're trolling, or stupid, or both (unless they meet the exemption above).

It's also nice to have a spare card down the line in case you want to sell one, repurpose the other, one dies, whatever.

The first dual-GPU card I think I had was a weird SLI on a card Voodoo1 that I got from an Id employee in 96 or so. The next one was a Rage 128 something or other (or similar, it's been too long), and it was almost unusably terrible.

If the card is clocked and cooled better than a pair of reference 290X cards. I don't see why it would not be faster.

Looks like its faster than 780Ti SLI Link
Maybe faster VRAM and better CF drivers?


AMD isn't using a CF bridge anymore. Maybe they have something on the board that mimics a lower latency PCIE connection between the GPU's? (total guess on that)

I know that is only one game at one resolution in the link above, but it'll be nice when we can finally double up on the >2 year old 7970 level performance for less than what it costs to do so now.

I don't see how those numbers are feasable unless the 290x 2-way CFX is throttling down quite a bit due to reference cooler or other unknown reason for lowered clocks during the bench.

295 should not throttle, but performance vs non throttling 290x xfire should be closer than ~15%.

Well sure, but who runs reference cards that would also be considering (and able to pay for) a watercooled 295? A pair of WC/OC 290X with good PCB design would easily beat a 295, just as a WC/OC 680 SLI setup dominated the 690, etc.

There are fundamental limitations that emerge with dual-GPU cards.

I think it's really just an epeen contest between NV/AMD to have the 'fastest single card' crown. Someone with a budget and a serious desire for performance would never buy one outside of the obvious exceptions (single slot but wants dual GPU, SFF with single slot, or dual slot but want quad GPU).

Someone doing a new build would be silly/insane to buy a 295 instead of a pair of solid 290X cards + water. Unless they were dead set on ITX or something goofy.

The Guru3D review you linked to is 780 SLI not the 780Ti SLI.

Here is 780Ti SLI http://www.guru3d.com/articles_pages/gtx_780_ti_sli_geforce_review,1.html

Basically when I made my comment yesterday, I googled 780Ti SLI review & Guru3D Review popped up 1st in which 780Ti Sli is faster than 290X CF, hence my post.

But even in the HardOcp review you linked before & Anand's review here http://www.anandtech.com/show/7492/the-geforce-gtx-780-ti-review


290x CF is faster, so I guess Guru3D has wrong numbers which led me to a wrong conclusion.

That's one heck of a case. I hope they have put that much attention to the cooling!!

/Not sure if sarcasm...

Does everyone online need a vision check?, that is a cheap ass oriental trading company case with a poorly applied glossy sticker.

Yeah that's pretty goofy. Pair of WC+OC 290X will handily smoke everything on that list. Stock 290X cards throttle quite a bit. It's a shame because the 290/290X are utter beasts, but really held back by gimpy stock cooling. Some GPUs don't have much more to give even with extreme cooling, but the 290s really open up a LOT.

Yes sure, a pair of WC+OC 290X's also have a large price premium of their own though. And you need 2 PCI-E slots now rather than one, and it's a bit more difficult to use quadfire, etc... It'll always be single card > dual-GPU card > dual cards.

This card was also made with the performance target of beating 290X and matching an overclocked 290X (1050MHz core clock, to be specific). You're just kind of spouting the same rhetoric as people do about every dual card, except this time the card is actually fast enough to make all your points kind of moot.

Ehhh... no.

Except price... You can get 2x 290X with aftermarket coolers that will sustain 1050MHz (apparently, I have no experience with them) for less than the price of the 295.

With aftermarket coolers, yes. He's talking about watercooled cards however, adding 2 waterblocks and a loop (or I guess an NZXT Cryo or whatever?) would bring the price to pretty much an even level. Either way, I just think this is a step up from using air coolers, and a change for the better.

Well, if is included in the $1500 price two binned golden Hawaii chips, then the deal is good.

Who will use this product clocked at stock clocks!?

Even if they are golden, I don't think they would OC as two separate golden chips.

Mad props to Anandtech, for not posting a picture of a damn briefcase on their website.

NDA's suck.

We will have to wait some more days. But all I see is a TitanZ owned in every aspect. Hope Nvidia can get a GTX790 as fast as this, without killing its own TitanZ. :biggrin:

Is that single RAD really enough to cool 2 of those GPUs?

It will most likely cool them enough so that it doesn't throttle down at the stock clock speed. However a single 120mm AIO even with dual fans (it shows only a single fan) won't have the capacity to remove the heat if you try serious OCing.

My 780 classified has an EVGA Hydro Copper water block and back plate with plenty of rad capacity for it and my 3930k OC'd to 4.5Ghz. I have the gpu OC'd to @1260 on the core (stock 993) and it NEVER exceeds 41C. Rad capacity and a true water block really makes the difference.

This promo has a quote from the CEO of Asetek about the cooling capacity of water. Trouble is I doubt the coolant in this system is distilled water; rather some other liquid with less cooling capacity than pure distilled water.

If I was cooling 2 R9 290s or 290Xs and wanted to do a respectable OC I would want 2-120 rad spaces PER gpu to keep it cool. It's hard for me to believe a single 120 mm rad will have the capacity to cool this sufficiently to allow any OCing.

Time for KaRLiTOs to chime in as he has 4 R9 290s WCed.

The fan on the actual heatsink would have to assist in cooling as well you would think. (Edit: probably to blow air on the VRMs now that I think of it.)
