[PureOC] Why We Need a $3000 GPU

post #1 of 10
Thread Starter 
Quote:
I can’t help but say that I’m really excited about the new Godzilla movie coming out next month. As a kid, I grew up on the old Godzilla films, had a decent number of action figures, and shared in the disappointment that was the 1998 remake. What I’m seeing now looks like a great homage to the old 1954 monster. This long lead-in would no doubt beg the question of what any of this has to with NVIDIA’s Titan Z. While $3000 sounds like a lot to average PC users, this card is a huge release for the movie industry.

The K6000 is an impressive card. It has 12 GB of on-board memory and 2,688 CUDA cores. It also boasts 5.2 TFLOPS of single precision floating point performance. As impressive as all that sounds, the Titan Z has the same 12 GB of memory, but more than doubles the total CUDA count at 5,760 cores and is supposed to have a theoretical 8 TFLOPS performance. That’s not the clincher though. A K6000 costs nearly $5,000! All at once the Titan Z doesn’t sound nearly as expensive as before. So while the Titan Z gave most hardware enthusiasts a heart attack with the specs and price tag, the film industry probably can’t wait to get their hands on them.

You could still buy two single Titans before Titan Z came out if you don't want/need a Tesla.

They do, and likely will continue to use Tesla cards.

Not sure how this is news.

It presents no facts, just someone trying to justify the $3000 price tag of a Geforce card....

There are quite a few issues with the Titan Z.

Viewport performance in 3D Apps will not be as good as the K6000, exactly because you lack the drivers (and no, you cannot just "soft-mod" it) + unless Pixar re-writes their engine + make custom drivers, SLI is "invisible" to most 3D Modellers.

It is a 3-slot design, which means unless you are talking custom water-cooling it, you won't be getting more than 2 or those in a ATX tower...3 in some occasions but that's it. At the same time you are completely loosing the ability to use dedicated GPGPU platforms designed around a 2-slot air cooled paradigm, like the Tyan FT77A that could support 8x GK110 already. With the 3-slot design, you pretty much break even (you can do 4-2*GK110 cards instead of 8x singleGK110 cards, for more money).

.

You are also losing lots of the K6000's VRam - which has 12GB vs. 6GB per GPU. The Titan Z has 12GB of usable VRAM only in the marketing brochures. This is pretty important for high res 32bit images being rendered with multiple layers etc = what the composite RAW file for production purposes of a progressive rendering engine is. ECC also not important for those purposes, as the "results" are graphics that get interpolated over 100s or thousands of passes, and not a single number that needs to be exact beyond the 17th decimal (or w/e gives FP64 the advantage over FP32). Even if that tone of RGB is off or corrupted, when averaged out with 100s of others, the result will be pretty accurate.

So yeah, if you shortsightedly compare apples with oranges, you might say the Titan Z is a bargain.

Too bad it is comparable with Titans, or even better 780Tis which also will have 6GB variants - as DP advantage is useless for the graphic GPGPU processes they are talking about - and not the Quadro K6000.

Me thinks that the source decided to relay the Pixar story, without knowing or comfortably ignoring some facts.

PS: I thought Pixar would be using Mac Pros exclusively. tongue.gif

How about the cost of a $5000 AMD card?

Should we consider them as GeForce miners now? tongue.gif

"the Titan Z has the same 12 GB of memory"

Um, no. There might be a total of 12GB worth of chips on that PCB, but it's 6GB per core, which means 6GB total. I really wish people outside of OCN understood this. Claiming the 7990 is 6GB or the 690 is 4GB is borderline false advertising. Should be advertised "HD 7990 3GBX2" to be as accurate as possible. I bet there's been some frustrated non-techie people have bought something that said "GTX 690 4GB" on the box but fired up GPU-Z only to see "VRAM: 2048MB."

Anyways, this article is completely stupid, there is absolutely nothing this Titan Z can do that a pair of Titan Blacks can do (at most likely higher clocks) for $1000 less, other than fitting in a micro-PC, and I don't know why anybody would be willing to pay a $1000 premium to downsize from a mid-tower PC to a micro-ATX PC.

The only other argument I could see is motherboard savings, because a MB with 1 PCIe slot is going to be a little cheaper than one with 2 PCIe slots, but it's still about $950 savings in total. Which is a no-brainer.
