PII vs AMD K6

[Snowman]

How come a PII 300 can do a seti WU faster then a k6-2 500??

PII- average time 22 hours

K6-2 average time 28 hours

The too systems are the same as in ram hard drive and settings
so what gives

[MrP]

Various reasons for it, but the main 2 are :

no cache on the k6-2
really weak FPU.

the cache really cripples seti and the fact that the floating point unit is about as much use as a chocolate fireguard make it a bad processor for seti.

you may get better results from a k6-3 (the one with cache) but i dont have any figures to say by how much

toodles :xsofa:

The 300 PII has 512k cash running at 150mhz.
The k6-2 has very little cache(16k + 16k) on chip and also depending on system cache which is slow(512k - 2meg).runnning at 66mhz or 100mhz. I had one of the 2 meg board and it did not make much differenece.

Mrp is a right the cache was the big difference. The K6-3 extra 256k cache does not really make a diffence. The FPU was crappy until the Athlon came around.

Back in those day the xeons and alpha processed with large amounts of cache (1-2mb) Kicked but. After 3.0 was intraduced the cache size is not as much of a factor(still is to a point,but not as much). Look at the new p4 512k cache come paired to a Athlon xp or t-bird. The xeon now suck. You have to love better coding. A better FPU is better than more cache.
