GeForce GTX Titan

[JulioCayetano]

Glimpse you have written exactly the same thougths I have about Titan but with better words so +1 for your comment.
Btw, I'm exactly in the same situation... I have a double slot free and waiting for a possible second gtx670 4gb, but maybe this Titan does surprise us and takes a place in our rigs... Who knows.

Announcement trailer : I wonder if they rendered this in octane?

first mini review, looks like this thing is for real

interesting comments on the SP and DP performance...


I'm a cheap Tesla, then?

The $999 asking price appears to be prohibitive to the gamer but can also be construed as a Tesla K20X on the (relative) cheap. This fact is further substantiated by the knowledge that, just like Tesla K20X, TITAN can run double-precision compute at 1/3rd of single-precision speeds, leading to over 1TFLOPS DP throughput. However, being a gamer's card at heart, TITAN's DP rate is set to 1/24th of SP, just like GTX 680, as no games use double-precision calculations. The full 1/3rd ratio can be set via the control panel, yet doing so forces the GPU's clocks down. And no gamer wants that, right?

NVIDIA ensures that those who are willing to pay for Tesla's feature-set continue to do so; TITAN doesn't feature the K20X's ECC memory, Hyper-Q and Grid Management Unit, amongst other $3,000-dollar niceties, though Dynamic Parallelism makes the cut.

Waiting for tests in Octane

[jmfowler]

Also waiting for someone to buy one and give some bench test results...

We should all chip in for the dev`s to buy it!

I would laught if someone buys a bunch of this cards and they dont even run octane without an update or so. Like with Kepler 680 series.

yeah, that's a problem =) but..because it's more or less the same architecture based on Kepler, just diff chip..I believe it should run out of the box =)..let's wait and see..

who wants to try? =)))

[smicha]

Let me guess:

2688/1536 * 837/1006 = 1.456 = 45% speed up?

We need someone to take the plunge for the team

Here s a link to the thread where GTX 580 was compared to Tesla K20 (Tesla K20 37% faster than a GTX 580 in octane).

However, Titan has been modified from the K20 to deliver more power in some areas, and less in others (like DP), so that's going to change the benchmark above.

I don't understand the internal architecture of Octane, but for me the big question is this : Can the GTX Titan outperform the GTX 690? It should easily outperform the 580 and 680. Gaming benchmarks put the Titan well behind the 690 true, however could it be possible that with titan's GK110 and Octane's reliance on compute performance, we might see Titan surpass the 690? If so the price tag of the card would then look more attractive.

Tempted to try myself, but at £800 a go, it isn't a cheap experiment.

I will get two (95% probability) and sent them back if they are not that faster as my two 580. No problem here in Germany to do so 14 days after buying online (doesn't not count for offline buying).
Maybe I will even keep one 580 too and only sell one. Would need another PSU then..
