anybody folding on a 4850 yet...

[MikeB12]

just wondering what ppd these are producing, since they are a $200 card with 800sp's...

I noticed some guy reporting folding on one at fah, but didn't post any numbers..

actually, ne has 4 with mir's, all around $170-180

OK, apparently that fah thread is going nowhere as far as getting numbers, and it appears from the comments it's not doing to hot on the 4xxx cards yet... no optimized wu's... I guess fah's focus has been on nvidia during gpu2 developement..

The 9600GT is getting 4030 PPD @ 775 MHz for the core / 1935 MHz for the SP. I don't want to post numbers for the 4850 (RV770) until Mike H post a new optimized core, or Stnaford releases bigger WU (more atoms) but I can tell that on current WU, the RV770 is a bit more efficient than the RV670 (3850 and 3870) at the same frequency, and it scales better with overclocking than the RV670.

Unfortunately, current WU are too small to fully use the 800 SP in the RV770, and I'm not even sure they use the 320 SP in the RV670.

I'm anxious to see some numbers on the HD4870, for gaming and folding. Guess we'll have to wait until early July for that.

If it doesn't fold it ain't good for me:down:

[MikeB12]

the 4850's will fold... there are just some issues with the code apparently, so they don't utilize all the sp's...

At the moment, the 4850 will offer little performance gain over a 38XX until we retune the code to utilize all 800 SPs. Basically, the current code path, besides having a few optimization issues in general on all boards, doesn't go "wide enough" to utilize the SPs. At the moment, a 4850 is a little bit faster clock for clock than a 3870, but the 4850's stock clocks are lower than the 3870s. Over the next weeks and months we will be tuning, we have some things in the works for 2XXX/3XXX still but most of the focus is on 4XXX, as well as getting the remaining stability issues fixed up.

The code needs to be retuned to scale from the 320 SPs in the 38XX boards to the 800 SPs in the 4850. At the moment, at least on the smaller proteins FAH is currently running, the 4850 is a little faster clock for clock than a 38XX, but the clocks are lower so it's currently a small drop in performance. We are tuning away, but it's going to be a little while until things are tweaked to utilized the 2.5X increase in SPs in the 4850 over the 38XX boards. We went for stability first, and are now just a little way into a heaving tuning pass. 2XXX/3XXX will get faster as well, but the 4XXX has the most headroom.

Things can only get better. I think they're getting ready for a massive fold assault with the 4870 along with a massive visual assault (Cinema 2.0 interactive graphical demo) to counteract the incredible pace of the Nvidia folding client.

-signed 8800GTX folder.. Hoping that the 4870 will whop the 5292PPD back to the stone age. :cool:

[blaH]

I guess 4850 is even more CPU bound, 3850 needs ~2,5GHz K8 to fully utilize GPU, although I guess running multiple GPU clients on same VGA would help quite a bit on 4850

Funny how the Nvidia client is out before the new ATI client:shrug:

What do you mean? It's the same client now,but different projects.
Take a good look at the pick: that was one of the first projects for the ATI's
client.

1. It was very similar to the current NV projects (seconds per frame),completely gpu bound and
was worth 30 points.
However if the credit was 98 like it is for NV right now, the total ppd
would have been just ~under 4000 (can't remember if I used 3850 or 3870 :shrug:)
Do you see what I am getting at ?
NV client is faster but not how most people think which is - twice as fast

btw that project is no longer running
Oh yea I am picking my 4850 up on Saturday, paid 199 CAD.
It's the HIS version came with Call of Juares and coupon for the freee "black box" from
Valve.
Maybe I should have picked another 8800GT:confused: too late now:rofl:

Does anyone know if 38xx and 48xx can be Crossfired ?

[MikeB12]

yeah, it's the same client... but I guess we won't see any good ppd numbers on the ati's until the code gets optimized or wu's get released that utilize all the sp's...
at least thats' the info I kinda stumbled onto after my OP aat the top of this thread..

in fact totow reported he's running a nvidia card and ati card in the same system on 2 clients. one of the OP links above...

- gpu 0 for the PCIe 16x board (4850)

anyway, later Mhouston posted later why the ati's aren't doing well yet. see above quotes in this thread.

-------------------------------------------
good luck on the 4850, Socket. I was thinking about one too, until I read that info from Mhouston about the code isn't ready yet... but who knows, a month from now they may have it all sorted. wait game I guess.. I guess in reality I'm waiting for 2 things to happen= 1. 4870 2. new optimized code to maximize ati sp's.

It's the 2 games and the funny screwdriver that sold me :)
I'll keep you guys posted how it folds.
I wonder now that the clients are the same, will the projects be the same also?
Ati has gone throe a crap load of different projects, even had 1 worth 1900
credits took 2 days to finish.:eek:
Nvidia (which is newer) only had 2 so far,both gpu limited, will see
I wonder how long it would take NV to finish #4716;)

That pick is the gpu2 client, guess you realized that
************************************************** ***
And a "royal" special here: no 4870 yet, that's the best I can do:D
I know 98% of the people who see it will think:
NV kills ATI in folding, well you are free to think what you want.
I tried my best to explain:) (earlier) To make a long story short: ATI needs something like "smpGPU" (just made it up)

[MikeB12]

Thanks for the numbers Socket... maybe we'll a see a code enhancement or core enhancement shortly that will allow the ati cards to load up and do their full potential...

kinda weird nvidia's code got optimized in gpu2, but not ati's. ATI may have not of had as much oil on hand as Nvidia to grease the wheels of advancement in recent history...

anyway, I have to wait until summer is over before splurging on a new video card... I reserved a beach house for family vacation in Sept that has to be paid for in the next 3 months, so goes my pc hobby budget until end of Sept.. maybe the ati/nvidia disparity wll be resolved by then..

[SocketMan]

No problem, mind you it's only 1 project so far.Family comes first no question
about it.There are other little things like an ability to watch a movie etc. with the ATI client running in the background but not NV.
I am thinking it comes down to the shaders:ATI has a lot more but NV's
are running at higher speed so "little" projects would run faster on NV and the
"future big ones" on ATI. I guess am lucky having the beach 25 minutes away:)
I've lowered the cpu speed by 200mhz there still getting the same ppd and gpu load (~99) increasing it first did not change the ppd

With all due respect Mr. mhouston, your posts remind me of Wimpy in the old Popeye cartoons. "Buy me a hamburger today and I'll gladly repay you on Tuesday." In this case it is: Buy our 4850-4870s today and you'll get some extra point in a couple months. :roll: All my current cards are ATI. The last 5 were purchased with folding in mind. I would be satisfied with my 3870s except for the fact I had to spend $200 on aftermarket water blocks for cooling and the fact Nvidia cards in the same price range are putting up over double the points. :roll: The Nvidia's are only using 20% of the CPU. AMD still doesn't have an answer for the Intel quads. For ATI to get kicked to the curb so easily made me forget about plans to purchase a pair of 4870s. Show us the points please! I'm sure ATI's 4870s do well for the gamers. Not all purchase cards for games. :wink:

************************************************** **********

The Villin WU folding now is only 500 molecules. Double the number of molecules, and the complexity goes up exponentially, and so does the need more shaders, etc.

When a new client is released, Pande Group starts out with well known proteins that are small and quick to finish. That way it is easy to see if the client is working well or not, and they get back lots of feedback very quickly. Starting with a small WU does both of those.

Besides, these were benchmarked on a ATI card. The NV cards perform very well on small WUs, ATI not so much.

All these performance numbers are VERY preliminary. Give it a month for the optimizations to settle in, drivers to get tweaked, an for some real (larger) work units to get folded, and then let's see where we are.

I sure wouldn't be making a buying decision based on the performance numbers for a client that is less than a week old.

[MikeB12]

I noticed they've added a couple new gpu2 wu's...

the biggest point one is a 5003 for 479points for nvidia... same number of atoms though, so I'm assuming it's just longer... so I doubt that would help the ati situation, it's probably just to help the servers not get so many requests for the smaller wu's from the nvidiia flood of folders..
edit: I copy/pasted the data of all the gpu2 wu's into a spreadsheet so it would be easy to see the current gpu2 wu's, # of atoms, and points comparison... from here http://fah-web.stanford.edu/psummary.html

[Kingcarcas]

Ok i'll remain calm, i was really starting to get ticked because i opted for the HD3870 (slower in games) over the 8800GT because it could Fold. Now i see those cards getting 6-7K PPD:shocked: Let's hope ATI kicks some butt in gaming/folding/price. :up:

[SocketMan]

Yea, you nailed it,
nice spreadsheet too, one project that I could not find any info on
was 4716, the one with the most # of atoms (~1800 credit)
Then again could have been the same deal as 5003 -just takes longer.

edit**
Your PC is still "functional" with ati: movies,flash or just windows 2d graphics even
With NV takes about 15 seconds to bring up the "menu" for the network card.
Both have + and - it seems,time will tell......

[SocketMan]

Time for an update on the "Red Front";)

Still a far cry (:p:) from the NV but it's getting better in terms of 4850
and ppd.
In fact I am seeing 2 cards on the same machine at 99% utilization for the first time ever.The cards are slightly OCed as well and the CPU is at lowly
2.8ghz.
Definitely progress.
