that's almost trivial compared to other issues. you have to learn to crawl before you can walk. for instance gpugrid, a DC project focused on curing diseases, attempted to make an ATi client based on opencl. we waited 2 months. the 5870 ended up performing as fast as an 8800gtx.

almost 2 years before this nvidia gave away free cards to gpugrid and helped them develop their acemd molecular dynamics software on cuda. gpugrid is currently the fastest bio-med project on boinc.

f@h is in the same situation. they want to make one good opencl client that can run on all hardware but they have to wait on stable compilers which takes time. i know this all sounds like a huge tangent but other developers eager to use gpu's are probably running into the same problems.

I tried to tell people about DP vs SP and how DP is better but no one really cared. I have been told time and again DP is much effective than SP for meaning full results

I thought DP was turned off on the Fermi (GF) cards and they are on for the Tesla cards.

**ajaidev** · 04-01-2010, 01:31 PM

Its not off gf100's DP power if barred by nvidia mainly to protect the tesla market.

I think its a bad move because if we crunch with DP its just more effective and better....

Sorry to thread jack again guys, but this review here has an nVidia GTX 480 running the "Heaven 2.0" Benchmark. It is running on an ASUS ASUS P6T Deluxe V2 and is suffering from the PCI-E Gen 2.0 bug. (as you can quite clearly see on the screenshots the card IS running in Gen 1.1 mode.) This is not a power saving feature.
Hopefully a more recent BIOS update for the ASUS P6T Deluxe V2 will resolve this bug.

Asus is being sloppy. They should have dealt with this by now...

GeForce GTX 480 Real World Temperatures & Sound
We have now spent some quality time with NVIDIA's Fermi in the form of its GeForce GTX 480 SLI and GTX 480 video card configurations. There has been a lot of talk about the sound and temperatures produced by these new GPUs. We look to put a fork into all the rumors and misunderstanding in the enthusiast community.

The Bottom Line

The GTX 480 is hot.

The GTX 480 is loud.

Okay so can we move on now?

**malik22** · 04-02-2010, 01:11 AM

are there any 470 sli reviews out there?

I have been looking myself...if you find one please post a link.

4870 shows 107.8C with little heat at the bottom of the case. This either shows that the test conducted is faulty or some fan (somewhere) wasn't working at the time the test was done. The same goes for the 4850 with their temps.

5870 shows 86.7C with some heat at the bottom of the case around 50C.

So what we have is completely useless results showing lower C temps making more of impact of the PC case then higher C temps. This makes the results invalid IMO.

You are confusing temperature with heat. They are related but aren´t the same. A drop of water can be at 90ºC but it will contain less heat (energy) than a gallon of water at 70ºC. There are components in a motherboard that can achieve high temps without releasing a lot of heat into the case. That´s the problem with the GTX480, it is transfering heat to other components despite the "cooler" temperature in comparison with the HD4870.

Case temps are clearly going to be higher with an exposed bbq grill like that. Wouldn't expected the 470 to push too much into the case though. Unless it has some air exiting internally
