Personally I prefer the ASUS approach to hybrid cooling with their ROG Poseidon range. This system looks tacky and more like a botch job to me rather than a professional design.

Considering the dual GPU nature I am surprised that no SLi or XFire set-ups were compared.

We would have had we had two samples of anything on hand. Sadly it was too short notice to get anything else in, hopefully we'll be able to for when Titan Z comes in.

Woot for AMD math

1 x 8pin power is 150w

so 2 is 300w and

the slot for 75 w = 375.

wonder where the extra 125w is coming from ;)

This card needs a lot more current per connector, so that's where :P

cant increase the voltage since that's fixed at 12v , so they must be stuffing more amps through....

Yeah, you need them connected to separate 12V rails that can each supply 28A.

It's pretty ugly. For that and the ridiculous price I think I'll pass.
Harlequin 8th April 2014, 14:10 Quote
so its openly way above pcie spec then?


since 175 (w)/12(v) = 15(a) or just under

this it it at 336watts per 12v rail....

That 4k performance makes it look fairly future proof. Were it more competitively priced vs Titan Black they could have a winner.

Guessing with regards to the BF4 bench, the mantle driver doesn't support this yet?

Beast card :)

Personally I think the box looks nicer than the card itself. Can't deny the performance figures though.

You can just tell that a few years down the line, this generation of GPUs is going to be one where we look back and ask "What the F*** went wrong with the pricing there".

titan black is like $1100 and titan Z is apparently $3000

Pricing is crazy, 2 780s or 2 780 ti or 2 r290x would be both cheaper and faster and probably consume less power in the nvidia solutions.

You could also likely afford to buy a seperate water cool loop with the 2 780s or 2 r290x setup.

Nice to see these cards made but they are for milionaires as id take the 2 seperate cards over duel gpu any day of the week. My last experience of duel gpu was awful and I wont be going back to it again.

As for 4k gaming this card or 2 of any of the mensioned cards will only satisfy you if you are happy under 60fps I never could be.

Performance wise maxwell should be alot quicker than the current cards and hopefully a more realistic price to boot ( have my douts on this one )

Computer technology in general pricing as gone up alot in recent years.

Cryptocurrency mining has been keeping the AMD cards' prices artificially high too. So the Nvidia prices are becoming absurd.

Wonder how much R9 295X2 would be without that watercooling kit? As anyone laying down that sort of cash will probably put their own block on and integrate it into an existing loop.

Seems that way, though I doubt that actually means anything.

Good performance for what it is and decent temps.

Still cannot think of anything else to say other than Meh!

reminds me of old school cards with the red transparent fans

The actual GPU temperature is probably closer to 70 degrees, though compared to even a single R9 290X that's pretty damn good, and as I said I didn't see the card throttling.

You guys should look over at Toms for the details of the power use. There is so much concern about it that they brought out the o-scope. It appears this card is only pulling 28W from the slot under max load and doesn't use the 3.3V at all.

If you look at the reference specs, the GTX 780 doesn't get a look in. The 780 Ti can generate more textures/s than the R9 290X, but the R9 290X can generate more pixels/s and more GFLOPS. The R9 295X is faster than a pair of R9 290X (same configuration, higher clock speeds, no reliance on a bridge or the PCI-E bus to transfer data between GPUs).

As such, I would say, except when your bottleneck is in texture processing, the new card is more powerful than any two single cards, at reference clock speeds. Also, the 780Ti and the 290X both have TDP of 250W, which doubles up to give the 500W of the new card.

I do agree though that the separate cards are much cheaper, this card really targets a niche market (maybe miners who want to fit as much processing power as possible into a single system unit). Or TG of course, he likes buying high end hardware :)

Separate cards may be cheaper, but if I had the money/desire I'd be tempted by making a stupidly powerful compact gaming system even at a bit of a premium.

Imagine a mini-ITX system build around this monster :D

Also the simplicity of two relatively compact all in one coolers would be a boon for such a system.

It looks like an amazing card and I know someone who wants one, or two. LOL. :D

pcper have a review of 780ti`s in sli and this , bothusing the very latest beta drivers...... at 1440p the 780`s are slightly ahead but above that the 295 is ahead - that's down to the wider back end , something drivers simply cannot do anything about - the ability to shunt a lot of data.
sandys 8th April 2014, 23:25 Quote
Quite nice, shame about the price, I'd be tempted to have one of these in exchange for my 3 290s, would drop power use and heat down for very little performance sacrifice I'd of thought.
