The prices are a tiny bit outdated, but gives you a great idea! http://golubev.com/gpuest.htmtake the MD5 number and multiply it by 62.63 seems to work well for the 5XXX and 6XXX series, but for the rest, it just gives you an idea in proportion. I'm guessing each series of cards have a number like the 62.63. another one with a lot less cards is http://pastebin.com/AvymGnMJyou can then put it here for your average time etc: http://www.alloscomp.com/bitcoin/calculator.php |

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

You can infer it from the MD5 data: ...take the MD5 number and multiply it by 62.63 seems to work well for the 5XXX and 6XXX series, but for the rest, it just gives you an idea in proportion. I'm guessing each series of cards have a number like the 62.63.
It looks like the 6950 should be slightly under the 5870, i.e. you won't get 313 Mhash/s, but you won't be too far off. The 6970 should be slightly better than the 5870. |

With an unlocked firmware on a 6950 I get ~292 Mhash at 800 MHz and ~321 Mhash at 880 MHz, both with -f 20 and poclbm. When I'm at home I usually run it at 850 MHz to avoid too much fan noise, and when I'm away I run it at 915 MHz (~336 Mhash). |

Not to self-promote, but if you find it interesting, I just posted a table of all the currently-available Radeons, with prices (looked up personally at NewEgg about an hour ago) and assorted derived stats in another thread: http://bitcointalk.org/index.php?topic=3814.msg55620#msg55620 |

self-promote away, this is to help people estimate Mhash/s with -v -w 128 -f 0 and 1040 core 300 mem, I get 278~280 Mhash/s on a 6870. yes, 6870. keep in mind that in games 975 core BSODs, let alone 1040, so don' t be affraid to OC specifically for mining. At stock I get 229~234Mhash/s |

Either the conversion factor for the 46xx series is off, or something's messed up with my miner config. I'm only getting 27mhash on my 4670, and 3 different lists are putting it around 37.

did you use -w 132 -f 0 or similar? f should be 30 or less for best performance. Also check GPU usage and clocks |

For 4670 you need to use -w 32 and no vectors.

My GTX 560Ti get's about 7100Mhash/s with -w 128 -f 30
I wish I had bought a competing AMD card like the 6950 :\
(Although I think mine is better for gaming)

I just picked up a Radeon 5850 for $149 at TigerDirect on Tuesday and out of the box with no overclocking I'm getting 270Mhash/s with "-v -w -128 -f 60" The computer is still perfectly useable and there's only slight screen slowness. I'd say the 5850 is the best hash/$ if you're on a budget.

I'm getting ~95 from my sapphire 4870 (OC'd to 848 Mhz with rivatuner, the temp is 77C average with fan set to 37% - nice and quiet, almost no screen lags) anything more than 848 mhz freezes the screen, so I'll just stick to it until I buy 2x 5850 |

If you can find them for the price, they are definitely the best. I decided a little too late to get one of the recert visionteks unfortunately. I managed to pick up a nicely used one local for $150 today though. Pop it in my system, load my preferred BIOS and it's getting 360 Mh/s ... 2.4Mh:$1 .. sweet! |

My Radeon HD6950 gives me ~405MHash/s which is better than the 5870 (afaics) It is: 1.Overvolted to 1105mV 2.core clock is 905Mhz 3.mem clock is 947mhz (due to system stability issues) 4.Shader unlocked. Hows that for a radeon Hd6950? Good modding skills or what? |

Hey, thanks for necroing this thread. I normally would say that sarcastically, but I remembered this thread, however was unable to find it for the longest time. I like the info contained within for many uses.
On another note, every one of my 5870s can reach about 430MHash/sec, and if I had a better cooling solution could go above that (I don't overvolt because they're all stuffed together without extenders).
