When will non-Fermi work units end?

Postby JimF » Thu Jul 28, 2011 3:22 pm

There was a post about a year ago that the non-Fermi work units would end, which obviously hasn't happened yet. What is the latest on this? I can't seem to find it in a search.
GTX 970 (i5-3550), GTX 980 (i7-3770); Win10 64-bit; FAH 7.4.4

If the past is any indication of the future, F@H had PowerPC work units available 5 years after Apple stopped making them.

GTX 480 was introduced March 2010, and the last of the GTX 200-series, the GTX 275 was introduced in April 2009. It will probably be a gradual decline in WU availability, as fewer project teams decide to run their projects on the older cores. I'd be very surprised if F@H flipped an "off" switch, which would eliminate a lot of useful, already-developed compute ability.

There is no new information on this, hence the lack of search results. No news is good news.

Keep on folding.

I''ve been out of the loop for a long time on GPU folding, just now getting things set back up. The bulk of my GPU cards are EVGA 9800 GT's (about 10 of them or so), couple GTS-8800's and a couple GTX-280's. Are these cards still worth folding on, or should I sell them and upgrade to the new GTX-5x & above series cards?

Need to update my sig too, it's way out of date :-)

Power efficiency when comparing ppd vs watt is something I'm curious to as well. The legoman666 spreadsheets aren't really up to date afaik?

My 9600gso was doing less then 3k, my q6600 can do more since it has the qrb ( this info is a month old or so, things might have changed with gpu points already ). Atm if you want ppd you're better of with cpu clients then gpu clients.

If you want to fold on the gpu, I think the nvidia's are using allot of power for not allot of points in comparison, but as always it's your choice.

Edit: viewtopic.php?f=52&t=11077 links are down, no updates since gtx285

You can get your hands on a 600 series card already?!?!?! :wink:

It is true that CPU's are where the massive points (and very nice PPD/W) are at. To be more specific, the Quick Return Bonus on bigadv WUs can result in hundreds of thousands of PPD with a suitably powerful system.

The major downside to bigadv is that a proper rig for it is on the expensive side. You need a computer with at least 8 CPU cores to run bigadv, and to start approaching 100k+ PPD you really need a multi-socket system. It is possible to run bigadv on an i7 because hyperthreading presents the CPU as having 8 logical cores (it only has 4 physical cores), but the Pande Group's best practices guide suggests that you not run bigadv on machines with less than 8 physical cores. Still, many people have set up standard single-CPU Sandy Bridge rigs since they can power through bigadv fairly well, especially considering their relative cheapness.

The true bigadv rigs, though, tend to run a much higher price because of their crazy core counts. From what I've gathered the high-producing rigs are 2- or 4-socket AMD rigs, often with 12-core processors. Those fetch several hundred dollars each, and that's not counting the cost of the motherboard, all the RAM, etc. Sandy Bridge Xeons haven't gone over 4 cores yet, and while you could probably scrounge around for 8- or 10-core Westmere Xeons, they're liable to be thousands of dollars each.

I did not mean just bigadv, regular smp also outperforms my g94/g92 nv gpu's.

I don't have any BigDave rigs that's for sure. All my CPU's are single quad cores flavors, so it would seem the winds of change have shifted back to CPU's. When I was loading out boxes, GPU's were the flavor of the day but it seems that's no longer the case. I guess I'll set back up on SMP clients and see how that pans out while I'm looking at what's needed for the BigDave Rigs.

I have a system with a 9800gt and 9800gtx that uses the same power as my other system with a 570, needless to say the 570 is atleast %50 faster than the other two combined

Do you have a wattage meter ( forgot the proper english term sorry :oops: ) so you could compare power draw from both systems as well, as that would be nice info!

Edit:

Trying to figure out the turnaround point for ppd/watt with current high end hw.

Doh, I knew the term.

So what's the power draw while folding? I know you say they use the same but can you give us a number?

Depending on how much overclock I use and the atom count of the work unit, they go up about 150 watts from idle usage

Wow that's actually allot less then I expected the 570 to use.. I thought they would gulp up watts like nothing before but 150w seeing their performance/points is making me want to buy some ( got to wait and see what santa brings this year :( ).

Thanks for the information!

I think the 570 is a bit under undilized with the current work units, when they start sending out the new 2k atom count units I can't imagine what the power draw might be
