STREAM client now available (beta)

[IronBits]

I like to keep an eye on things for rc5 here to:
http://teamstats.macnn.com/rc572/sta...sort=StatsWeek

I'm almost at the level that 10 PS3s and a Mac Mini could do.

[Mustard]

well you don't have to worry about staying ahead of me as I've got a few too many things on my plate at the moment to be able to run out and rpelace everything with super hot running streams..... :-) Not that the thought hasn't hit my little head..... What's got my eye are those really high end cards, like the thousand and couple thousand dollar ones..... maybe for christmas.... LOL

edit: But yup, I can definitely see that the stream cards are going to walk all over the cuda stuff unless nvida makes a bit of a jump to get ahead in the game again.

edit: edit: And what's going to happen with the new PS3's? It's looking like they will be a tougher nut to crack, not that that stops anyone. The main thing they have is low power consumption in comparison.

[IronBits]

Well, not sure about that...
The PS3 does about 1/2 the performance, 3000 blocks per day for 114 watts.
vs ~250 watts on the video cards for 6000 blocks per day?
Fairly close... and I'm sure there is some tuning to do on this Stream stuff.
Plus, the PS3 is $300 and a ATI OC video card is $225 right now and I'm sure that price will come down over the next several months, as they always do.
At least it's interesting! I'm tired of the basic same old CPU, just more of them, with not much of a Hz increase... It's like CPUs stalled out.
I expected 10GHz by now, sheesh.

Your HD 4890 at 680.0 Mkeys/sec should be doing ~13,400 stats units per day.

[IronBits]

Oh ya, 6000 per day is what I get with the nVidia cards. duh

[alpha]

It would be interesting if we could get some performance comparison numbers between Windows and Linux on the same hardware. Any takers?

Looking at the official stats, the Linux Stream client has already completed twice as many blocks as the Windows version. I'm not saying there's anything to read in to about that, but perhaps the Linux client has an edge?

[Mustard]

The linux stream was the first one worked on and released. The windows one was just released. Keep watching and the windows stream will pass the linux one, just like what happened with the cuda stuff. As for the cuda, there wasn't any diff really between the linux and windows so I wouldn't expect any real difference with stream. My understanding is that the card output is the same between 64 and 32, so distributed.net just releases 32 bit cuda/stream clients. However, like many things in life I find out, I just possibly could be extremely wrong on this. LOL

[alpha]

Ah, OK.

I've got a 4870 coming this week so I'll hopefully be posting my numbers too.

[Mustard]

Well rats........... you people keep getting all this high powered new stuff instead of just the "average" new stuff and I'm going to have to hurt my bank account...

[alpha]

OK, my 4870 is in, and up and running:

0.00:00:07.46 [581,464,636 keys/sec]

A touch slower than DP's. I'm running 32-bit XP and had nothing running on the CPU at the time. Client priority was default.

I had to do some SERIOUS molex plug splitting and daisy chaining to have enough to get everything running. I really hope it holds up under load until I can swap some things around.

What are people's temperatures like? I'm running at 90 C, and it definitely feels like it being chucked out the back!

Over double the output of any nVidia GTX 285/280/275 series for 1/2 the wattage, because I only have to run 2 cards instead of 4.

[IronBits]

Actually, the output is better than the benchmark.

Real nice... For comparison how fast would RC5 crunch on one of your CPU cores?

[IronBits]

To put this into perspective, an
My I7-920 at 2.8GHz, with 4 hyperthreaded cores (8), does 29.2 Mkeys/sec

Well, from this thread alone we can summarise:

HD 3650 - ..57.3 Mkeys/sec: 194? watts: 120 shaders
HD 4650 - 174.9 Mkeys/sec : ..55 watts : 320 shaders
HD 4850 - 489.1 Mkeys/sec : 110 watts : 800 shaders
HD 4870 - 589.5 Mkeys/sec : 150 watts : 800 shaders
HD 4890 - 680.0 Mkeys/sec : 190 watts : 800 shaders
HD 4890 - 740.0 Mkeys/sec : 200 watts : 800 shaders : Core Clock 950MHz : Memory Clock 1050MHz

Also, check this Wikipedia article. It's a neat comparison table.

It looks to me like core clock is more important.

[Mustard]

So how many of those 4890's have you got stashed in your closet cranking away for the big dump IB????? Just thought I'd ask as that sounds like something you'd be springing on us. LOL

I just went for a couple of the 4850's, so if something broke, I wouldn't have all the eggs in my basket broken.

But then maybe I need to get one of them there rocketships and upgrade my stable a little bit and get rid of some of the slow gpu's. LOL

[IronBits]

I only have the two cards running.
I turned off everything else to save money on electricity.

[IronBits]

10 years at $300 per month (average) = a lot of coins
Then toss in the price of all the computers I have bought, upgraded and given away to make room for more upgraded computers,
in the interest of Distributed Computing FTW and humanity...
It boggles the mind...
I am preparing for and getting ready to retire in about another year or so...
It's time the younger generations stepped up to the plate, or not, it's their world now.

Looks like you bought your ATI cards a tad bit early. Double the FLOPS with the new gen card and some other goodies: http://www.anandtech.com/video/showdoc.aspx?i=3635

[IronBits]

That's always seems to happen to me. I might get one, might not.
Double FLOPS is always a fantastic leap

[Mustard]

yup, as you say IB it's a fantastic leap, but it's just a continuation of the game that's been going on that is basically designed just to separate you and your wallet from as much as possible. And like you mentioned above, some of us have been playing this game for quite some time. And sorry to say, I'm growing a bit weary of it as the old excitement just isn't there anymore. I too have put a small fortune into this game and have already retired. So I think I'll most likely just take a pass on the new stuff and the new prices, etc., etc., and just join the bystanders.

[IronBits]

Understood.
That new card has twice the processors, prolly the reason it's twice as fast

[Mustard]

funny how they don't mention anything regarding the price.

[alpha]

So, does anyone have an HD 5xxx series GPU yet?

I'd love to see RC5-72 benchmarks of the:

5850 (1440 stream cores, 725 MHz)
5870 (1600 stream cores, 850 MHz)
5970 (3200 stream cores, 725 MHz)

This looks promising for the future:

5990 (3840 stream cores, 850 MHz)


So it seems whatever keyrate the 5870 gets, we can roughly multiply it by 2.4 to get the potential keyrate of the 5990.

[matrix_fan]

did they remove all of the stream clients permanently?

[the-mk]

there is one Stream client in the prerelease download area for x86 linux...
there are also a lot of new versions: 516... maybe it is working out the next few days, so we are able to download some new prereleases

[alpha]

The Windows Stream client had expired before they removed the download link, so I'd guess another beta or release candidate is on the way.

[the-mk]

now there are Stream clients for Windows in the prerelease area - needs just some time to work out

[alpha]

MrJackson2000 @ Ars has posted RC5-72 benchmarks for his 5870.

1900 Mkeys/sec.

That means, with 10,000 of those cards you could exhaust the entire keyspace within 8 years.

[Digital Parasite]

Wow, that is fast. The scary thing is with 10,000 of those cards it would *still* take 8 years to exaust the entire keyspace...
