Best 4XX series GPU

siegert81 · 2011-04-23, 21:13

I've noticed that the 500 series GPUs are quite expensive. What's the best 400 series Nvidia GPU for number-crunching purposes?

460 should give you best bang for the buck.
470 is more powerful, but is also hungry for power.

I read that 560 should be the best choice.

I'm very happy with my 460 --- reasonable price, reasonable power consumption --- but you should go for the 1GB version as the price differential over the 768M (my model) is no longer as significant as it was last summer.

I recently installed a 1GB EVGA GTX 460 SSC in a Dual Core Intel E5700 setup and have been pleasantly surprised with how quiet it is.

Even when the GPU load is 99% the fan doesn't have to go above 50% to keep the temp at about 65 degrees.

Two instances of mfaktc have the CPU and GPU at 100% producing maybe 130 to 150Ghz-Days per day.
cudalucas did a double check on 26238437 in about 60 hours, which seems roughly equivalent to to how long the E5700 would take.

I just thought I'd add - I bought 2x GT430s for some ex-corporate systems.

They aren't flash, but they were ideal for the situation. I bought some cheap corporate Core2 Duo systems for about $150 each. The power supply was only 200W. They had custom fitting power supply in the case, so I couldn't replace the power supply. It was also a low profile case.

It really wasn't worth me buying a new case and a new power supply. But buying a GT430 did the job. The power requirements are small - it doesn't need those 6/8-pin power cables. It gets all it's power from the pci express port. It's suits a low profile case.

GT430 does around 35-40 GHz-days/day on mfaktc. Faster than single socket CPU only system.

It's not the fastest GPU on the block, but may suit someone's situation.

...and did I mention they are cheap.

How's your noise level on the 430? I've got a 440 ($90 us) since it didn't push the original PS on this box. I think the 440 can do 90GHz days/day, but it's a bit noisy....and definitely warm...

I have other noise sources that are drowning it out. So it's hard to tell.

There's the GT520 out - and you can get completely passively cooled versions. Completely silent.

A bit noisy = I can hear it in the other room, acceptable.....I'm waiting to find out what a GT480 sounds like, have one of those available as soon as we ensure we have power supply and monitor and cables available.

On further thought on the GT440: The slow, periodic changes in tone and volume due to fan speed changes bother me more than the absolute volume. Any way to set the fan speed to a minimum, which should be more than sufficient, and above that annoying mid-frequency peak?

Windows users can use Afterburner or some similar tool from another card manufacturer to create a custom fan profile. Linux users can override the fan settings via the Coolbits option. Changing the fan settings seems to work on Fermis.

You should keep an eye on the temperatures if you lock the fan settings and disable the automatic fan control: Over the time the cards will collect dust and this will lead to higher temperatures if the fan speed is locked.

I was looking for a quiet GPU upgrade that can do some GIMPS work. Currently on a passively cooled 7600GS. Looking at
http://www.dabs.ie/products/gigabyte...?refs=55040000
or
http://www.dabs.ie/products/asus-gef...?refs=55050000
or even:
http://www.dabs.ie/products/asus-gef...?refs=55050000

Which card would be the best bang for buck? Is a 520 even worth the GPU output? I like it because it is passively cooled.
