[TWITCH] NVIDIA unveils the Titan Z - Page 68  

post #671 of 747
I don't understand the compute argument? Most of the compute benchmarks show the Titan Black getting easily beaten by the 290x? Should the 290X cost a couple grand too? The Titan only wins in F@H from the benches I've seen.

Titans are all about double precision. So this is the relevant compute benchmark:



Restrict the double precision performance and we get the 780Ti at a way lower price.

Okay thanks for clearing it up. Why is double precision so important?

On the whole, it isn't. But it's crucial for those people who are involved with very precise calculations that the 64-bit DP makes possible. For most everything in day-to-day computing, single precision 32-bit is well and truly precise enough.

Well honestly those folks most likely would end up getting a professional cards anyway. I don't really see compute as a real argument on the price. The justification for the price would more likely be due to Nvidia being considered a more "premium" brand than AMD.

Most would, but there is no question of whether or not DP plays a role in the pricing of Titan products. The VRAM difference is a part of the price premium between Titan Black and 780Ti but not all of it or even most. It will become evident when the 6GB 780Ti is available.

DP is a part of the premium profile of Titans. It is of absolutely no use for most of us and that makes the premium pricing a bit hard to understand. Suffice to say that the original Titan outsold Nvidia's own predictions, so there clearly is a market segment that considers the premium justified.

I only skimmed through the post, pinocchio, I never outright acknowledged anything about compute

Claiming they will be compared to gpu's?? They ARE compared to gaming gpu's

As far as the compute thing...."marketed at professionals" c'mon....its marketed at anyone willing to buy it

Nvidia says "Here is our dual gpu graphics card, only marketed at professionals of course wink.gif we'll just price it $3000 and leave it right here"

They're not marketing at professionals, they're testing the water....

Maybe because geforce cards are gaming gpus?

The funny thing is that AMD never restricted DP on high end cards until this generation. Did anyone justify the 7970's $550 price tag with "well it's got full double precision it's more than just consumer card"? NVIDIA artificially limited its cards, then deided to charge a gigantic premium to remove this limit, and its fanboys are justifying it.

Oh, and by the way, a true professional card has ECC (like the 7970 had...) and professional drivers and support.
