How fast do the fastest computers generate bitcoins?

I only have a 1Ghz netbook running bitcoin at the moment, so I’m curious what kind of bitcoin generation rates the faster computers get. 100/week, 1000/week, 10000/week? How big of an advantage is there to having a faster computer?

my CPU amd turion 2 cores rated at 1.6 Ghz generates 50 BC in 2 days…

100/day seems pretty good… Does internet connection speed matter? Also, does it matter how long your computer has been continuously connected?

Nope and you can only generate when you have all blocks, so you won’t generate for the first minutes of starting Bitcoin. Doesn’t matter past that.

I’ve noticed that hashing performance doesn’t vary as much between CPUs as you’d expect.  Compared to an old CPU, a newer CPU doesn’t show as much of a speedup at hashing as it does on general benchmarks.

I guess recent CPU optimizations must have concentrated on things like I/O and branch prediction.  Most programs are a bunch of memory access, comparisons and branching, they rarely get down to cranking away at maths for very long.

The latest SVN version has a khash/s display.  Around 400 khash/s per processor is typical.

That what Wiki pages are good for:

For example a computer with 6 x ATI HD5870 did 2568 Megahashes / second. RESPECT!

Any particular reason you felt the need to resurrect an 18 month old thread?

If you want to practice thread necromancy why not try it on a useful thread? Really a thread debating various CPU performances?

oh man … 100 btc a day and more…with a cpu 😢
