boincadm/DA has done a couple of changesets: #24069, #24071 and #24072 that shows the Top GPU models here at Seti, (the link is beneath Statistics on the front page),

I assume this is with the Stock GPU apps, as Linux, Mac and ATI/AMD are unfilled.

Interesting, thanks for the link. Some thing doesn't look right in the line-up though.

We also need to work with David to help him refine the list into something more useful.

The stated thinking behind the list is:

I added a page that shows the most productive GPU types,
total and by platform:

This will at least provide suggestions for which type
of GPU board to buy.

-- David

It looks as if the data is being pulled from recently returned results, so it should be up-to-date. But so far (and it's very early days yet) the list would be positively misleading as a buyer's guide: for a single card, no way can 9600GT>9800GT>9800GTX+ be right.

I presume the scores must be strongly influenced by the number of each type of card in use here: the 9800GT was pretty much 'most bang for the buck' three years ago, and there'll be lots of them around, but that doesn't make it a 'best buy' in 2011.

Do we have anyone reading the board today who could analyse gpu_list.php, and work out exactly what's being shown in the lists? My guess is that it's the raw total credits for results in the database for each card type - and I'm wondering if it might be for people running stock apps only.

My first suggestion, given space constraints, would be to add the count of cards in brackets after the model name, and to sort the list by average (total/count). But I'm sure between us we can help make it even better than that. Any ideas?

Is this based on computation potential or purely the number of cards that are present on the project? Surely it can't be based on processing power, listing a 9600GT over a GTX580...

Perhaps it is just total contribution based on card type?

A quick look suggest it's counting number of results in the last day for each model. I'll look again to check when my eyes decide to cooperate better with the PhP code.

[Edit:] I would suggest, if that's so, that it reflects a compound value of raw performance x number in circulation of each model, rather than performance alone. They would need to divide the figures by some complicated figure based on active hosts with the given model. Unfortunately Boinc doesn't identify mixed card setups properly, but if a count of the cards per machine is available it might provide something 'near enough'

and i vote for an overview of incoming results of the last 30 days, but like jason said, thats near enough

Yep, that looks a bit more reasonable, some figures would be nice, and what happened to the 8400 GS? has it dropped off the bottom?

The code in [24085] seems to consider the first 5,000 results it encounters in a list of tasks created in the last 30 days. With SETI turning over 50,000 tasks an hour, that's a pretty sparse sample - my guess is that the 8400 GS just hasn't reported in the last 5,000.

It's still not right - although David (brownie point for this one) has skipped tasks running for less than 100 seconds, basically the -9s - he's done nothing to account for shorty storms. I'd prefer to see a page like list of recently connected client types, with some explanations and cautions. And like that list, I'd like to see the query run periodically, and the results cached - the time it takes to refresh the 'Top GPU models' page suggests the code hits the servers pretty hard. Caching the page would help, though hopefully with a refresh interval of less than 10 months. Remind me to try and find a way of celebrating the anniversary of the current list ;-)

What about double chip grafic cards: 9800GX2, GTX295, GTX590?

As I looked GTX295 #13, GTX260 #11.

Maybe x2 or /2 (depend of how the place is calculated), so the double chip grafic cards are higher placed.


1. GeForce GTX 570
2. GeForce GTX 580
3. GeForce GTX 480
4. GeForce GTX 470
5. GeForce GTX 560 Ti
6. GeForce GTX 465
7. GeForce GTX 460
8. GeForce GTX 280
9. GeForce GTX 275
10. GeForce GTX 285
11. GeForce GTX 260
12. GeForce GTS 450
13. GeForce GTX 295
14. GeForce 8800 GTX
15. GeForce 9800 GTX/9800 GTX+
16. GeForce GTX 560
17. GeForce GTX 460 SE
18. GeForce 9800 GTX+
19. GeForce GTS 250
20. GeForce 8800 GTS 512
21. GeForce 9800 GT
22. GeForce 8800 GT
23. GeForce 8800 GTS
24. GeForce GT 440
25. GeForce GT 240
26. GeForce GT 220
27. GeForce GT 430
28. GeForce GT 330M
29. GeForce 9600 GT
30. GeForce 8600 GT
31. GeForce 9500 GT
32. GeForce 210
33. GeForce 9400 GT

With so few tasks sampled and so many gpu's, and with the processing of mid range AR's and VHAR's havin at least a 30% variation. This exersize seems pointless and misleading, especially if it takes up a lot of server power.

It is nice to see that -9's etc can be disregarded, now maybe Dr A. can apply it where it is most needed, calculating APR.

This is what the Top GPU models list looks like now:

1.GeForce GTX 590
2.GeForce GTX 570
3.GeForce GTX 480
4.GeForce GTX 580
5.GeForce GTX 470
6.GeForce GTX 465
7.GeForce GTX 560 Ti
8.GeForce GTX 460
9.GeForce GTX 285
10.GeForce GTX 275
11.GeForce GTX 260
12.GeForce GTX 295
13.GeForce GTS 450
14.GeForce 8800 GTX
15.GeForce 8800 GTS 512
16.GeForce 8800 GT
17.GeForce GTS 250
18.GeForce 9800 GT
19.GeForce GT 240
20.GeForce GT 430
21.GeForce 8800 GTS
22.GeForce GT 220
23.GeForce 9600 GT
24.GeForce GT 330M
25.Quadro FX 580
26.GeForce 9500 GT
27.GeForce 9400 GT

some GPU have now made the list, while others have vanished like the GTX 9800/GTX 9800+, wouldn't it be better if it was a running average of app times, ie update the list, don't make a new list.

A performance graph would be nice ;)

For example I'm using both GTX 460s and 560ti's, but there is quite a price jump, I wonder if the performance increase reflects this - I'm still trying to find out from my own tests.

Useful information though, I'm not sure how it compares to other performance comparisons which I tend to refer to when buying new stuff... also referring to power consumption and price.

The Top GPU models list now has some numbers, not sure what they mean:

They're relative performance, presumably what fraction of the current 'top dog' each card is achieving.

I added a new web page, html/user/gpu_list.php

This shows a list of the top-performing GPUs for your project,
broken down by vendor and platform. For example:
http://setiathome.berkeley.edu/gpu_list.php

The performance figures shown on this page are not
the manufacturer's peak-FLOPS claims;
they are the actual performance for your projects' applications,
based on job runtime info from your database.

Projects with GPU apps should consider adding this to your site
(to do so, just upgrade to the latest web code).
Your users will be interested,
and it may influence their GPU-buying decisions to your benefit.

It may not have been there at first - I got it from an off-list email. He may still be tuning the code - it hasn't been committed into trac yet.

This should help answer those "best video card bang for the buck" questions.

I wonder how big of a mess it would be to do this for CPUs as well.
