Difference between Athlon 1.3 vs Duron 800 in SETI?

[RossMAN]

Title pretty much sums it up, this is assuming I'm using 256 to 512MB PC133 RAM.

I would estimate a Duron would do WU's in about 9hrs ish whilst the T bird would achieve about 5-6 hrs.

Anyone with hard figures?

Meanwhile you can check here for some benchmarks from the Edge teams site.

Assim1, Those times are pretty close.

That's pretty significant, the cost difference isn't that much between a TBird and Duron, I'll prob go with the TBird then.

RossMAN, I bought 2 Duron 750/mobo combo sets for $99 each well over a month ago from Fry's. I tried them first on SETI and was so bummed at the results that I switched them to RC5. I have since purchased a 1.2GHz Tbird and it does really well on SETI. Some days it will spit out 5 WUs in a day! 😀 I tried it on RC5 and it hung after only 30 mins. 😕 Wouldn't think RC5 was more demanding than SETI, but that is the second Tbird that has happened on.

Thanks JWMiddleton, I'm glad that AMD has such competitive pricing because I can probably get a TBird/IWILL mobo combo for $300 or less shipped.

Yep the TBird will be tons faster! 😀

I just upgraded to a socket a mobo, and had to go with a 800 Duron due to lack of funds.
I'm running it at 8 x 111 = 888 Mhz and that gives me an average setitime around 7,5 hours.
Now i'm saving up to a Palomino to put in my mobo 😉

That's pretty good!:Q ,my PIII 650 @ 820 does most in about 7hrs!

What WU times were you getting with the Durons?

 

[JWMiddleton]

Assim1, I had to check the SetiSpy log and I found that it was doing a standard WU in 8:30. I changed it to a 1GHz Tbird and the time dropped to 6:39. I hadn't planned that switch, but someone may me a really good deal on the 1 gigger. The 750 Duron is currently in an ECS mobo doing RC5 where it performs as well as a PIII @ 910MHz.

I just checked the log and my PIII-650/840 averages 6:45. It has Crucial CAS2 RAM with max settings in BIOS.


toft-dk, Excellent time on the 800 Duron. I saw on Pricewatch where an 800 Duron/ECS mobo combo w/HSF is $89 US. This has thinking of upgrading my Mother's PII-300. 😀

The T-birds have the bigger cache (as compared to the Duron), so for SETI, T-birds will always do much better. Same when comparing a P3 with a Celly II.

For something like RC5, the Mhz will make more of the difference when comparing the T-bird to the Duron.

Interestingly, I haven't tried SETI on my Duron 700@954 (mainly because of that cache issue), but on my P3 600@972, SETI runs ~6.10 hrs/WU for mid-ARs and under 6 hrs/WU for the high ARs.

 

[RossMAN]

What are ARs?

 

[Poof]

Awww.... 🙂

AR = Angle Range.

The way the SETI client is setup, depending on the angle range of the WU (ie., how the telescope was tilted when the data in the WU was recorded), certain types of analyses are performed on that WU. So for example, the very highest angle range WUs (eg., AR = >1) have much less analysis performed on them than the mids (eg., AR ~0.2 - 0.5). Same goes theoretically for the very low (eg., AR < 0.1). However, there is a bug in the WIN CLI that makes the very lows take longer to process than normal, despite the fact that they should process almost as quickly as the very highs because not much is being looked at in them.
