GTS 450

[Frizz]

I just got a GTS 450 (MSI Cyclone) to do some testing and wanted to share some benchmark results with you.

Summarized: It's nothing world-shattering. My GT 240 crunches one typical WU in about 20 minutes, my GTX 460 needs 11 minutes. The GTS 450 needs 16 minutes. Power consumption while crunching: ~70 watt (only for the GTS 450).

But the MSI GPU cooler is awesome - even under load it's never over 35°C.

[EDIT] Added results of GT 240 benchmark for comparison plus WUs.

Have you got any comparisons with other cards and these wu's?
Depending on price it may not be a bad entry level fermi card

Looks like I will be able to see some decent SETI speeds about Monday, that should be when my GTX 460 arrives.

Sorry if this was discussed before, but I didn't wont to open another thread for GTS 450.
 If I test it with cuda 2.3 GTS 450 throws invalid results, so it looks like she is not backward compability, or that is only temporary?
Thanks for any answer.
I have same card as member that open this thread.

Hi Pepi.  Cuda 2.3 has no support for Fermi architecture.  Only Cuda 3.0 onwards.

Your choices are stock 610 or x32f from the latest installer 0.37 .  x32f is better than stock (less errors & a tad faster)

[Pepi]

From CUDA 3.1 log

* Adds support for CUDA Toolkit 3.1 which includes significant performance increases for double precision math operations

It look like a boost when CUDA 2.3 was released, and she was way faster then 2.2

I was testing Lunatics verse 6.10 stock, and Lunatics was only faster 10 seconds ( on 364 seconds result)
So hope that  3.1 or even 3.2 and more optimized application from Lunatics will make this difference larger .
Also must notice one thing: 240 has only 96 cores and 450 has 192. But 450 is not double faster then 240. And has also much more clocks of shaders, memory and gpu. Why?

[Raistmer]

Boost not for SETI cause it's single float, not double

[Pepi]

And second one?
....240 has only 96 cores and 450 has 192. But 450 is not double faster then 240.....

[Jason G]

Also, Cuda 3.1 has bugs (when running Multi-GPU) that makes it not useful here.  Cuda 3.2 fixes these but is not released to the public yet. (Guess it is)

[Jason G]

And second one?
....240 has only 96 cores and 450 has 192. But 450 is not double faster then 240.....

Also Fermi optimisation has only just begun.  There is a long way to go.  For now the focus has been on getting a build that runs with less errors.

[Pepi]

So hope is not vanished for GTS 450?
That is great news!

[Jason G]

So hope is not vanished for GTS 450?
That is great news!

It's a brand new card/chip that isn't even in the Cuda documentation yet.  I can't predict what the final capability will be, but it should be more than what we get now 

[Pepi]

So all I need is waiting And hope that SETI will live enough time
