AMD's athlon number rating? (according to folding)

[Quailane]

Hey, I just got a new (to me) 1.33Ghz athlon thunderbird. To test it out, I put it in a pure folding rig, taking the 2100 pally out of that one temporarily. What I found was astonishing. The pally rating of 2100+ means it should be equal to a 2.1 Ghz thunderbird, but it actually is at 1.73Ghz. Well, guess what, the 2100+ got 26 mins a frame on a work unit, and the 1.33Ghz thunderbird got 41.5 mins a frame. It took me forever to figure out how to compare them, but I finally realized that multiplying the pr rating or processor speed by the minutes is the correct way to do it. 2.1x26=54.6 and 1.33x41.5=55.195. Pretty close huh? Proves amd's pr ratings are true, at least according to folding.

There's no arguement there that the old PR system was accurate. Up to the 2400XP model. After that AMD was just going crazy with these numbers. Back in the day the 1800XP was able beat out a 2.0 P4 Northwood.

Bandwidth wasn't even part of the arguement, most P4 systems were armed with RDRAM which only supplied 3.2gigs. Latency problems with RDRAM allowed PC2100 to catch up most of the time. Low latency 2,2,2,5 PC2100 versus the high latency nature of RDRAM allowed the athlon to dance on the P4 most of the time.

I thought the PR was susposed to compare it to a P4. I guess thunderbirds have about the same effiency as p4s. :eh?:

Well, technically it is not supposed to compare to a P4, but I would not doubt it if it was, if you kinda get what I am saying. If they actually compared it to a P4, they would have to supply tons of benchmarks and things to prove it was as fast as that P4 model, but if they just said they were comparing to the thunderbird, that would be alot easier right?

But yes, it is based off of the thunderbird, as said, up to about the 2400 model. I beleive they are going to go nuts with the Sempron line, but we just dont know for sure yet ;)

Ah, I see. It's like: this compares it to the thunderbird *wink*wink*, but it might compare it to something else.

Kinda, yea... ;)
