Since I myself am losing the oversight on the various miners that are currently available or in use I started a wiki page that might introduce users to alternative miners: http://www.bitcoin.org/wiki/doku.php?id=bitcoin_miners
It would also allow us to collect some real world comparisons about how they perform against each other Cheesy

Performance shouldn't be measured in multiplies of the CryptoPP miner. Maybe you could give hashrate examples for typical CPUs.

Just a few threads, that you should have read, if you want to complete your bitcoin miner wiki site.

Well the problem is that there is no typical CPU, or typical GPU for that matter. So you'd have to write down exactly your configuration and test that same configuration against all miners. I was thinking more in terms of list the requirements, and then what you usually get when fulfilling the requirements. It's not meant to be precise, it's just indicative of where users can go with certain miners. If results then vary +/- 10% the user wont care.

It's a wrapper around the Main client, not a miner flavor.

Looks like the patch by puddinpop, I have no viable benchmarks on this one.

I'm quite interested in this one, would like someone with a good GPU posting some benchmarks.

This is the main thread I took the idea from, but except puddinpop's code, it's all just generic talk.

Help the little ol CUDA developer:http://bitcointalk.org/index.php?topic=1324.0
These are improvements to code that exists elsewhere

Again just a fundraiser for puddinpop's code.

This one I actually didn't know yet Smiley

Prehistoric thread on how to build the main client on Mac.

Anyway the wiki is open, feel free to add anything important Smiley

Oh and since I don't have a GPU in my notebook (not one I could use anyway) I'd be especially interested in benchmarks of the CUDA and openCL miners, since I can't provide them myself.

GPU Benchmarks for OpenCL:
- ATI 5770: 170000 khash/s
- ATI 5870: 300000 khash/s

OC'ing the video cards:
- memory OC: no effect whatsoever, to save energy best to underclock gpu memory
- gpu frequency: performance goes up to 320000 khash/s at 850MHz

On the ATI5870, this means generating 1 block every 30 hours (at this moment).
