Another GTX 580 data point:
4x EVGA GTX 580 1.5GB (797MHz default): 1m 43s
This test definitely doesn’t scale so well beyond 3 GPUs. Still, the above result
with four cheap 580s at least shows the economy option for those who can’t afford
780/Tis or Titans. 8)Ian.

It’s ok though, a friend is sorting out an insanely intesive
AE/CUDA test for me, which in its present form takes about
10 mins to render one frame using four GTX 580s. 😀Ian.

Oh I see! Apologies, I missed the different name of the
Titan card. 😀 Just curious, what is the core clock of
your Titan Black compared to the Classic you had before?Btw, a couple more data points, using a 5GHz 2700K setup
with 32GB/2133 RAM):Quadro 6000: 8m 7s
2x Quadro 6000: 4m 36sAlso, in case it’s of any interest, I’ve added some
Viewperf12 data to my site, for the moment using the
above 2700K system (which shows some major CPU bottlenecks
in several cases – looks like Viewperf12 needs more than
4 cores):https://www.sgidepot.co.uk/misc/viewperf.txt

Hi Teddy! Just wondered if you saw my reply to your post on
your old benchmark thread – can your new test suite be run
with AE 11.0.4?Ian.

Just curious, what did you do to speed up the result for
the single Titan? Or is it purely the change in mbd?Btw, I find Arion to be a useful test, as it fully utilises
all GPUs (AE doesn’t do that yet).Ian.

2xTitan is correct. Hopefully though soon I’ll be able to
show how multiple GPUs can scale more effectively than
this benchmark is able to demonstrate; test file is not
quite ready yet.EDIT: Quadro K5000 does the test in 8 mins and 4 secs,
though this was on a different system with a lot less RAM
(ASUS M4E, i7 2700K @ 5GHz, 8GB/2133).Ian.

That’s similar to why I like the P9X79 WS (basically the same type of
board as the R4E); the newer E-WS has a better PCI Express setup, but
people have reported more problems with it. The standard WS is very
reliable (I’v ejust bought another one, only cost 170 UKP).> … one advantage of this board:

empty slot between each card for 3-way CF/SLI. Alas this is not the case
with the WS, but it doesn’t matter because I chose the MSI LE version of
the GTX 580 (runs much cooler, totally different design to the reference
board, designed to cope with oc’s above 1GHz).It’s a pity nobody makes a super-extended board with 7x PCIe, spread
across at least 10 slots, giving much more cooling space between cards,
and greater options to exploit additional cards such as RAID or 10GigE.> I’am thinking about the ASUS P9X79-E WS too, but with most cpu coolers

the back of the first GTX 580), because I was using a large Phanteks
PH-TC14PE. I’ve solved this by replacing the Phanteks with a Corsair
H110, so now there is plenty of space around the CPU area, much easier
to access RAM, cool components, etc.For the next 3930K system I’m building for someone just now, I’m using
the same mbd but fitted with a Corsair H100i instead.> consumtion and heat and maybe i will get some (additional) lags during

of the WS is better support for RAID cards and more reliable with maxed
out RAM configurations, heavy loads, etc. Gaming doesn’t really stress
the whole system that much, but various pro apps do, eg. AE can hammer
all parts of a system at once, far more than any game.> Another interessting board: ASRock Fatal1ty X79 Champion

I doubt it would make any difference in reality, but I can understand
why it would feel annoying.There is of course the Asrock X79 Extreme11, but that’s overkill, not
really aimed at gaming. It’s more akin to the ASUS WS series, though
the lack of onboard RAID cache spoils it IMO.Ian.

Can you RMA you motherboard? What model is it? (just curious)
Note that Gigabyte GA-X79-UD3 boards sell quite cheaply these
days – I bought one for only 65 UKP recently.Ian.

The adjustment to the supported cards file should work fine,
just make sure the name matches the identifier string in GPU-Z.
In your position I’d stick with the Titans, though for AE the
780Ti is the more sensible card to use, or it will be once we
can get a 6GB edition.Ian.
