Overkill3D - PowerColor R9 295X2 Crossfire

Introduction

Roll up roll up. Yes it's that time of year again when we dispense with such simple considerations as affordability, efficiency or even sense. It's Overkill3D time, which means that if you're a recent lottery winner, a descendant of Rockefeller or perhaps a Prince killing time on their favourite website, this is exactly the test for you.

We recently looked at the PowerColor R9 295X2, a graphics card which comes equipped with two of the top-end Radeon GPUs, the Hawaii XT's, all kept just about cool by an All-In-One (AIO) watercooling solution. The numbers we attained were incredible.

Still, if loads is good then insane amounts is even better. So let's grab another R9 295X2 and test out some Quadfire gaming goodness. There is a thread there. 4K resolution. 4 GPU test setup. We're too good to you. 

But we know you're not interested in our preamble, you just want the benchmarks. So do we.

Test Setup

PowerColor R9 295X2 Quadfire
Intel Core i7-3960X @ 4.6GHz
ASUS Rampage IV Extreme
Corsair Dominator Platinum 2133
Corsair AX1500i
Corsair Neutron GTX
Corsair H100i
Windows 7 x64
ASUS 4K Monitor

What's that you say? How much power does this thing draw at 4K resolution? What a fortunate question you've asked there. Needless to say such a monster arrangement when coupled to the incredible 4K resolution certainly isn't the kind of thing to be attempted lightly. But this is Overkill3D, nothing about it is small and 1321W being pulled from the wall is the higest we have seen here to date. The power draw actually goes up by nearly 100w switching from 1440p to 4K resolution!

Two Hawaii XT GPU's not enough performance for you? Won the Euro Millions? Step this way...

Awesome video, Is it just my eyes or is the lower card sagging quite a bit ?

Dem benchmark scores

Pretty decent scaling in some of the games, over 100% in some of them which for quad fire is good.
And to think, you can get this set up for just over the price of one Titan Z

EDIT: make that 400 less than one Titan Z

Hmm, the scaling is actually surprisingly disappointing.

Edit: BRB, switching my eyes. Yeah, scales quite well, don't know what I was looking at.

100% percent scaling in certain scenarios disappoints you

Up to 100%+ is pretty good and that is at 4K.

Excellent video! "For all you AMD trolls, go back in your cave, cover your self up and shut up"! almost wet myself, with 1300w at the wall what is the wattage while idle with the second card switch off...

"That's my P scores" Phrase of the week!

Great video review Tom.I have a couple of R9 290X Tri-x laying about,i sometimes add one of the to the R9 295X2.But then i remove it because i don't feel comfortable pulling 800 watts out of my wall.

Lovely video Tom. Man that would be an awesome overkill rig for folding on. As long as you could keep it cool. On a good note, the system doubles as an office heater in the winter.

Awesome video, especially that power draw! That sag though on the bottom card

Insane, in all ways from heat generated to performance. As far as I know, Quad Crossfire/SLI isn't even technically supported.

Always love the jab at trolls/fanbois too.

and now the scores of a Titan Z please, just for shits and giggles... considering that a single Titan Z costs as much as two R295X2 + two full cover water blocks for them I think I know where my money would go... if I had that kind of money, that is

SB-E hexcores can cause problems with Quadfire Hawaii

I had to swap out my 3970X for a 4930k to get my single cards to run properly. Another guy with a similar setup to mine also had to do the same.

Another good video. I've been waiting for this for a little while now. I would love to see some F@H numbers from that rig.
