We are looking forward to testing the new nvidia architecture. We will report the performance soon and really thank one anonymous cruncher for the donation.

As I am going to do a new PC build later this year, I'll be interested in these results. I have seen several "gamer" oriented reviews that also tested "compute" capabilities, and I was not impressed by the compute results. All compute tests except for one were slower than previous gen cards. So, I still hold out hope that the GTX 680 will perform better than the previous gen cards.

As a summary of what I have read:

Power consumption is down quite a bit - TDP is around 195W under load.
Games run faster.

Its not much, I know, but that pretty much sums it up. ;)

... I'll be interested in these results.

Just like we all are.

I have a bad feeling

WARNING: The GTX 680 is **SLOWER** than the GTX 580

THAT's on an LLR-app which heavily relies on 64-bit capabilities.

it was pretty obvious right from the start, that GK-104 design was not planned for that.

The GTX680 has 100% more flops and 30% more transistors than the GTX580. We would be happy to have something in between those numbers.

Due to the fact that it requires cuda4.2 which is still experimental we are thinking to release it as a test application.

PG-sieve apps which are still cuda 2.3 do work. maybe not using the full potential, but they produce valid results.

With cuda4.2 I think that we will be within the window of performance I indicated before.

I thought cuda 4.2 was still under NDA. Would a cuda 4.1 app be a reasonable compromise? At least 4.1 is publicly released so we can beta test.

Besides given all the driver sleep bug issues people are not likely to have a 4.2 capable driver installed at the moment.

BOINC blog

cuda4.2 is publicly available from nvidia forums but not widely advertised.
You need the latest drivers to run on gtx680.

We have now two GTX680 installed locally and we are now testing the BOINC app.
Thanks for the donations.

any result?

Due to Easter holidays, we have a stop now. The BOINC cuda4.2 application is being tested though.

Just got my 680 in, unfortuantely I have to have it on Windows for gaming, and would like to know whether or not I should attach it to the project yet? Don't want to be returning a whole bunch of invalid or errors.

I'm not sure what the situation is. Gianni indicated that he might release a Beta app, and the server status shows 17 beta tasks waiting to be sent. It's been like that for a few days. These might be for Linux only though?

You need the latest drivers, and as far as I am aware, the GTX680 will not run normal or Long tasks. So I suggest you attach to the project, configure a profile to only run Beta's and see if any come your way.

HOW TO:
- Opt out of Beta Tests
- Ask for Help

It appears that they are Linux only. If I wasn't running out of drive space, i would give this rig the dual-boot, since I now know how to configure it. Don't feel like using usb, since im running wcg currently. Might go pick up a larger SSD in order to accomodate this weekend.

Just keep Windows. We use Linux because it is easier for us, but we should be having a Windows application soon after.

First off let me apologize for the "tone" of my written voice, but after spending 6 hours last night trying to install ubuntu i can say I HATE the "disgruntled" GRUB. Windows 7 install refused to play nice with it. Kept getting grub-efi failed to install on /target error, as well as MANY others. Even went to the trouble of disconnecting my Windows SATA connection, but still kept getting same error on fresh drive. Do to the fact that it is Easter Weekend (and the habit of wanting betas ala WCG), I have decided to unistall Windows 7 in order to accomplish my goal. Since this is mainly a crunching rig (0 files stored internally, I keep all on external encrypted HDDs), and besides the one game 1 game I play (which was ruined due to a recent "patch"), having Windows does nothing for me ATM. Should have this uninstalled shortly, and hopefully with it unistalled maybe GRUB will not be so grumpy (as well as me).


Happy Easter

P,S, Isn't learning fun. ;)

In order to crunch anything at all - beta or otherwise - you need both a supply of tasks and an application to run them with.

The standard BOINC applications page still seems to work, even if like me you can't find a link from the redesigned front page. No sign of a Beta application yet for either platform, which may take some time pressure off the OS (re-)installs.

Literally getting ready to de-install before you posted that....... Is that because those beta wu's can't be sent to anyone with the designated platforms unless they have a 680 though, meaning they don't want them to go to people who have the other apps, but without the proper GPU to run them?

EDIT

I wouldn't think they would even bother loading betas unless they were ready to go out. Meaning why bother loading them, if you're still testing in house. I would ASSUME it may not be listed in apps, for reasons stated above. Even though it is odd that nothing is listed, maybe that's just because the app doesn't matter, since this beta is related to hardware?
