Hi guys,

Help...
Please, try and talk this out of my head and give me good reasons (other configs) not to buy a machine with 2x TitanZ when the in my head wants to spend 5.5K euro.
(probably it will be 6.1k with upgrade RAM and CPU water,
but basically it is 5.5K with i7-5820K, 16GB, 2TB, 250GB SSD)
I have seen other threads about TianZ, 780's adn more,
but I did not want to hack someone's thread.

greetz,

Hi, Rappet.

I wrote a piece ago about TitanZ with OctaneRender =) some things have changed: nVidia felt the pressure of red team (aka AMD) as their DualGPU beast (aka Images R9 295X) was in comparison with TitanZ but for half the price =) So nVidia came with evil plan to cut price for TitanZ to 2k$ for boutique builders..& so the AMD slashed their price by 500$ to 999$ & not only for boutique builders, but for all =) I guess the end user wins out from these moves.. =) let the fight continue!

Now how about value =) well at 2K$ plus system TitanZ makes a lot more sense. Just think about: TitanZ is actually the first dual GPU card that comes with full set of vRAM (580 came in 1.5 & 3GB, while 590 "only" in 3Gb but in two chunks!!!, 690 had the same story.. =) thus TitanZ is a bit of different beast compared to any previous dual GPU cards - probably that's one of the reasons why nVidia felt so relaxed with stratospheric price for gaming card..

However, my opinion hasn't changed too much - & if it would be my money, I'd probably go for 3x780 6Gb (if You can find them) or even TitanBlacks under good waterCooling loop - this would get You the same performance, but lower price, better thermals, less noise =)

Last but not least Titan Z makes most of sense for Small Form Factor (mITX, LiquidCooled, OCed to ceiling..) builds - Bolt II from DigitalStorm or TikiZ from Falcon Northwest

Though there's one more situation.. =) If You take EK water block for TitanZ, what You get is two slot card (as it includes dual slot bracket! =) Now think of 4cards, 8xGPUs inside regular case (with some extra space for radiators) - that's a beast & without any need of PCIe Expandetion boxes (these usually cost ~2k$) or extra licences if You go multiple rig route. In that scenario, if You can get TitanZs for 2k & building a monster - that fairly good deal =) that brings back the value if You do things right =)

..just some food for Your thoughts =) keep spinin'

Thanx Glimpse,
I was hoping for your wisdomness
I' ll get back here with my thoughts after investigating more about 780 6 gb.. I think I might get my hands on 4 of them
Greetz,

hehe, looking forward to hear what You came up with =)

ghm, think I need to write 2nd part on TitanZ =)
like looking from different perspective on it..
as with time You start seeing things differently =p

Is this correct: the 780 (6gb) is not a dual 2x 3gb, but just one 6gb like the Titan,
And it has the same 2880 cores and same corespeed 889.
So the 780 6gb is100% like Titan 6gb?
I must be wrong, because why can I get my hands on those 780 for 'only' 500€ and Titans are 900€?
Am I overlooking something?
Greetz,

Am I overlooking something?

No, 780 is a bit slower than Titan, the 780Ti is a bit faster but only 3 GB.
Titan was really for extreme gamers with big pockets.

Cheers, mib

780 has "cropped" DP performance (compared to Titan, TitanBlack & Z), that on OctaneRender doesn't make any influence at all. 780 is a bit slower than Titan, but 6Giggers come with nonReference coolers : If You manage to space those out so they would have plenty of space to breath You can get extra performance & they perform on par with Titans (some users on this forum confirmed that =) & thus in theory & in practice 780 6gb for us, Octaners performs the same as Titan..

the problem is..after nVidia released 980/970..these 780/780Ti & 780 6Gb was discontinued.. - at 600$ 6gigger was a bargain..if You can get Your hands on those You'll be lucky =) maybe some retailers even make a discount for You =)..but it's getting harder to spot those, especially if You need more than one or two..

Hi Glimpse,
Thanx again for your thoughts... That helps a lot.

I did some math in price ratio performance and investment.
I came up with this config as good choice, wanting not only 3gb and not wanting to spend more then 5k:
TitanZ + 2x 780Ti (3gb) for 4.500€
Greetz,

I don´t really see the point of having a Titan Z (2x6GB) and 2 780Ti (each 3GB).
It means your VRAM is limited to 3 GB for GPU renderers....?

as nvidia dropped the price for Zs I've noticed a thing online =) Guys where buying bundles from boutiques & then selling Z between 2-3k$, as it seems this card has a bit of a demand =).. then for let's that money they buy 2x780 6GB - to get better performnce than TitanZ & still have 1/3rd of cash left in a pocket =)

I was really tempted when I saw Z for ~2k.. (as any e-tailer will keep the price around 3k$), but couldn't justify performance/price..Latelly got happy as I couldn't found 780 (6gb) - only STRIX, that I honestly dislike - but then used TitanBlack came into sight for the price I was willing to spend for 780.. =)

@Gueoct, I guess he has mixed workloads & for some scenes he might not need more than 3gb =)

p.s. I would love to see TitanZ under water - curious what performance You could squeeze out of it in OctaneRender, maybe You looking that way? if so, please post some stats as You go =)
