GeForce GTX Titan

[darkline]

Looks like the card really does exist. Many specs here but found the below interesting for octane :

Performance - Faster or slower than a Dual-GPU GTX 690? HD 7990?
If you decide to use this card for GPGPU, for example password cracking, this card should be able to beat the K20 and K20X without breaking a sweat. The company castrated the Double Precision, and you can expect great Single Precision performance (2,688 CUDA cores time 875 MHz should result in around 4.5 TFLOPS SP from a single chip). Double-precision follows the Kepler tradition of 1/24 Single Precision performance. Yes, 4.7 TFLOPS SP and 196 GFLOPS DP, nicely protecting Tesla K20/K20X and the upcoming Quadro K6000 products.

The chip commands pixel fillrate of 49 GPixel/s and texel fillrate of 196 GTexel/s (once more, Texel fillrate is identical to FP64 Double Precision), while 384-bit at six billion transfers per second was enough for amazingly high 288.4GB/s.

Preliminary results show that in 3DMark Fire Strike (Extreme), GTX Titan scores 4870. According to our own testing, this would put the part some 500 points (10%) behind two GeForce GTX 680s in SLI mode. Given that single GTX 680 achieves around 3000 points, almost 1900 points fewer than GTX Titan. Bear in mind this is still not enough to beat a single GeForce GTX 690.

Rather far away from the 690, though OpenCL is a diffrent thing and this fluid simulation is more of thing for AMD cards.
Price tag is rumoured to be at 1000$ which would be similar to the GTX 690 at launch. Paper launch Feb 14th and Feb 26-28 actual shipping.

Im really addicted by the 6GB Vram. Still fighting with myself if I get 2 or not.

I've been waiting to upgrade for a looong time. If this performs well in Octane, I'm sold.

[photonf]

Is octanerenderer using single precision calculations ?

if yes titan specs sound really nice

otherwise even a (couple of) gtx 470 would be faster than 'titan'

[Daniel]

If what this article says is true, the Titan should have great SP performance.

[mbetke]

Yes Octane only benefits from SP performance. This is why the K20 doesn't performs so well at the moment.

[darkline]

As far as I know Octane doesn't use double precision, only SP. So the titan should be a good solution. In another thread I think it was Gabriel who benchmarked the K20 with octane and said he got a speed increase of about 40% over a GTX580.

While that isn't staggering, the Titan could beat the K20 benchmark further out of the box (or this article seem to suggest that). Bear in mind also this is with no optimization for the GK110 GPU by octane developers, which so far has only been designed to make the most of 'little Kepler' (GK104). So that could boost things further.

All speculation still, but the 6G ram alone is a good reason for me to get one, even at speeds close to the gtx 690. I'd be curious to know if anyone on the octane team has tested a K20 and sees any untapped potential for acceleration on the GK110.

Jut read in another article (also speculations only) there will be only 10.000 units of Titan. Paper launch?

[glimpse]

I wouldn't be surprised about quantity if we are ever going to see this beast. NVidia probably would not like to canibalise their profits from Tesla range, thus this card probably will be very highlypriced & in limited editions as it will probably use somewhat faulty chips, that don't live up to expectations to be put into K20(x). There is no need or any benefit at all for cards like these in games, but this is a nishe where is a lot of demands for those who have more money than pocket space =p at the end we alll know that cards like these would be interesting solution for profesionals who would like to build their rigs on budget, but so far all of the info online is like written with the stick on water..- nothing concrete..- it seams they're just writing it to get more trafic to their websites..let's wait a bit, maibe we'll see big Golden Kepler =) the other question remains unknown..whether Otoy team would manage to squeze that extra potencial from them..hope so =) have a slot reserved, if not going for second 670..
