GTX Titan is out...

Post by HuggiL » Tue Feb 26, 2013 12:30 am

If anyone ever gets, or knows someone who has/buys a GTX Titan, see if they can do a run with MediaCoder's CUDA encoding. I am curious as to how having 2688 CUDA cores stacks up against the 680 (1536 cores) and the 690 (2x1536, although I'm not sure how SLI factors into this).
I seriously wish I had $1400 (**** Australia Tax putting that extra $400 in) for this card...
In theory, theory and practice are the same. In practice, they are not.

Matey - i recently upgraded from a gts250 to a gtx650....

3 times the number of cores....

bugger all difference in speed.....if anything its marginally slower :-(

adding insult - the gts250 was about 50% utilised according to gpu-z....
the 650 is 70% utulised....

i don't think mediacoder will take advantage of having more cores :-(

there may be other factors at play, but various posts around the internets have net me little response....

hope no one wastes their money like i did....(albeit the gtx was only $130 and is quieter)

I have a GTX650 too :D got it for $50, brand-new, off someone who got it as an unwanted gift.

Shame that MediaCoder doesn't utilise the extra power. I wonder if all CUDA is like or it's just MC?

Matey -

Wish it were otherwise....but i have tried them all - free,paid - you name it....

They mostly all disappoint - especially the paid ones - the quality is woeful,
and the encode times are a joke.
The one that Nvidia used to sell is particularly bad....

Mediacoder and one other make the grade as far as i am concerned - won't mention it here,
but it's also "free" and you can "make" pretty good encodes with it ;-)

I took the GTS250 and put it in the kids dual core e6750 machine -and guess what?
using mediacoder and cuda, this ageing setup equalled the speed of my newer setup.....
that has 3 times the number of CPU and GPU cores....

Strange... Then, how does one increase the speed at which CUDA encodes?
