I've found a lot of the memory to be of a different quality too. Generally the Rx cards perform much better for me. Keep in mind, at the factory a lot of the cards have IDENTICAL hardware, and then they test them at various clock speeds. Some work better than others, and that's often the deciding factor if a card gets branded as an OC model or not. Ultimately that's the result of imperfect manufacturing techniques. Same thing applies to processors and basically everything that uses today's ultra small fab processes.
Thats what I had in consideration i think its called binning (transistors) but I believe that they also add some safety margin just in case. Thats why you can always overclock instead of having the oveclock preapplied (notice that it wouldnt be called overclock then) AND that safety margin is the MHz that enough cards (in their opinion) work with that MHz |

Number of stream processors units (SPUs) is usually a good guide.
thanks anything else i can use? |

The upcoming Rx cards are supposedly going to smash records on the price/performance ratio.
Given that all their specifications are known how can one calculate their hashrate???
(with exact same settings of course)

The R7-260 series aren't rebranded either. They have an new audio system and processor.
I've read that many cards come with faster Ram and worse power block (low cost VRMs, capacitors and so on...)
They will tend to hash better, but failure rate may also be higher. For example, most 7870's have an hard time to reach 400 Kh/s while the Gigabyte and Sapphire R9-270 can touch 500
is it only because the new cards are overclocked compared to the same/similar  YES/NO |

Ive just found that AMD renamed its 7770 to R7 250 and its selling it as another product.
Update Ive found that all Rx are rebranded except R9 290 series.(I guess thats why these arent on hashrate lists online)
Am I correct to expect exact same hashrates as from the original not renamed versions?

R7 260x can do about 250 Kh/s
thanks Im adding it to my hashrates list, any other R7 kh/s you can share? |
|
|
|
It can't mine coins because it does not have the architecture.
im looking at the R7 cards any reason they arent so well known? I could only find r9 hashrates. I would like to know R7 hashrates please |

Just for fun, download and run demos made for the Radeon 8500, 9700 and 9800XT. Some are really awesome!
what do you mean by demos? |
|
|
|
The device does not support OpenCL, it is not programmable.
ok thanks what else should i do with it then? |

I have no idea what to do with this hardware. It is old but it is very good and it works excellenty as it should.It can play 480p video sometimes even 720p without lags.It even can have 40+ internet tabs open functioning without problems.For office work or internet it is good enough.You dont anything more powerful to just do that.
But because it is perfectly usable and it wll be just doing nothing I wan to know how much kh/s I can get just for the fun of it.
So how many kh/s?Or what else would you do with it?

Source? I've been doing this a very long time. Go out and get a multimeter and test it yourself, as I did. I've tested the current draw of every type of card I use. people are looking for a source on something absolutely simple to test.
If you want to see pcie specs, google it. Each 6 pin and 8 pin connector has a design specification, as do the motherboard components, and every electrical device. Much easier to just test it.
hahahahahaha multimeter??!?!?!?!?! do you know why you shouldnt test psu (or anything else?) with a multimeter? why proper reviews use laboratory equipment worth few grand? please answer back Hey kid, do you know how to test current draw? It's not hard, and doesn't require lab equipment. When you try to be cute, don't do it with professionals. Ive personally measured voltages and current of my psu.Then Ive read how stupid it is.Search about it on google. (Hope you dont have kids.) |

How does it show how many bitcoins I have earned by posting?
where are those bitcoin youve earned by posting? (r u stupid?) |
