About that Bitcoin vs. F@H thingie in the comments:

Unlike F@H Bitcoin has a 100% stable algorithm that has to be executed on every worker. F@H or any other BOINC project might update their algorithms over time and invalidating the older benchmarks. Bitcoin mining only might make use of updated OpenCL kernels if someone discovers that there is a more efficient wasy of combining some AND and OR instructions or the like. The algorithm itself ("SHA256(SHA256(header))<=Difficulty") won't change though.

Are they going to start using correct miners?  They were showing the 7970's max mining potential as 300mhash or so for a long time, while you could easily get double that with diablo...

Yeah it might be too much to ask but it would be nice if they ask for HERE for some assistance of proper mining configurations.

I mean yeah there is some variance depedning on the particular miners and params but 300 MH/s for a 7970 is just a useless datapoint.

Also, if anyone wants to do a straight swap of my 6970 at an impressive 390MH/s for your 6990 at a pathetic 389MH/s, we could work something out.

You can see their updated results here http://www.tomshardware.com/charts/2012-vga-gpgpu/14-GPGPU-Bitmining,2970.html

Which still seem too low. I know the 7950 I have gets 414 at stock clocks with cg miner and that's what their 7970 gets.

My 7970 gets over 550mhash at 950  core and under-clocked memory.  I don't know how they come up with that result.

They have no idea what they're doing. I have to imagine that the 6990 is mining on only one GPU and they figured that XFire would take care of the rest. How else do you explain it getting almost the same but slightly lower performance than a 6970?

Should send them an email letting them know that I would retest all their cards using a couple miners to get the optimal settings for each, if they'd be willing to send me all the cards for a couple months. Smiley

Doesn't go into operating costs or anything.  Also a 6990 is faster than a 6970, lol.  I'd take their results with a grain of salt.

Anybody on here also members of Overclockers.com or [H]? Do they have Bitcoin subforums yet? Those guys are big fans of crunching projects so it'd be good to have them on board.

[H] has a distributed computing sub forum with a thread for Bitcoin. Most of it is F@H however. We are generally more interested in builing 4P systems for F@H on the forum.

XtremeSystems has a bitcoin sub-forum but it receives very little attention due to WCG being the primary project over there.

Since their BTC benchmarks are so untrue and it seems they have little will to do anything to inform themselves to correct this, it makes me wonder if indeed all their other benchmarks could be of the same rubbish quality Roll Eyes
