[hashcash] Re: Speed problem with 1.03 on Mac G4

The dual-G5 Xserve is about 9 gigaflops, for $2,000. That's $222 per gigaflop . A company called Orion Multisystems have just announced a workstation offering between 18 and 36 gigaflops for about $9,000.... Works out at between $250 and $500 per gigaflop. But I wonder what sort of hashing performance it would give?;


I have absolutely no idea. The gigaflop is a (crude) measure of FPU performance, and hashcash doesn't touch the FPU at all. The Efficeon is a weird chip, too, and it's very hard to predict how any particular code will perform on it. It's even difficult to benchmark it, because it changes the code out from under you by dynamic optimisation.

It's probably safe to say, however, that each Efficeon chip will be considerably slower than each G5 chip, seeing as the G5 stands head and shoulders above everything else in sight, and benchmarks show the Efficeon as being slower than most of it's rivals.

Apple unveiled the new iMac G5 today... All this talk about G5's just makes me want to go and buy one! :-)

*"Apple has unveiled its next generation of desktop computers, the iMac G5, at the Apple Expo 2004 in Paris.* It is the first iMac to be powered by the high-speed G5 processors, used in its Power Macs, and is touted as the world's thinnest desktop computer."
