Hi Setyanto,
We have already discussed about GTX590 and I will use this message to give some additional information and details. I have two of these cards.
My initial benchmarks were not so correct because it turned out that (during my tests) when I use more than one GTX590 the cards work with limited speed of 553Mhz, i.e. they reach only to the performance level 2. With simple words my tests were performed with downclocked GTX590's. At full speed of 612Mhz I obtained:
DHFR NPT benchmark
GTX590 1 core 22.05 ns/day
GTX590 2 cores 31.89 ns/day
GTX470 18.82 ns/day
GTX580 about 28 ns/day
As you can see from these values indeed the GTX590 is faster than GTX580 but if you use two GTX580's you will probably reach 40 ns/day against 36 with two GTX590.
For the more realistic case:
FactorIX benchmark
GTX590 1 core 4.55 ns/day
GTX590 2 cores 7.26 ns/day
GTX470 3.65 ns/day
GTX580 about 5.5 ns/day
Here I was a bit surprised and enjoy because as you can see the difference between 2 GTX580 and 1 GTX590 is not so big (about 8 ns/day against 7.3) and GTX590 is really about 100% faster than GTX470. However again, if you use 4 GTX580 they will be faster than two GTX590's.
I was not able to solve the downclock problem with my GTX590's till now. To be honest the Nvidia support was not great too. They supposed that it is just a PSU issue but after many tests both my and their results showed that indeed the PSU's are not the problem and it is "something" in my systems, but never received any suggestions what could be and how to solve the problem.. I think it is just a driver problem, because the cards work great with the older drivers but ..not for CUDA applications. Anyway...
I also have to mention that GTX590 works very good for QM and some docking applications. For instance for QM calculations two GTX590's are really great performer and even clocked at 553Mhz they are much faster then pair of GTX580's.
So if you plan to use many cards and only for MD calculations then GTX580 is definitely the better choice, but if you plan to use only a single card then GTX590 will perform better. Also if you plan to run multiple jobs at reasonable speed, with GTX590's you can safe PCI slots. Personally I use GTX590's and GTX470's and will upgrade the latter's to GTX580's.
Regards,
Filip
P.S. According to the rumors/news a new revision of GTX590 is expected in June, which hopefully will solve some of the power issues.
