I have the Sapphire OC Dual X Radeon 7790. My measurements show about 3.44 to 3.78 MHash/watt. Depends on Machine -- this is a 1200MHz overclock and the memory slowed down a bit.

fwiw

From looking all those sites previously, it looks like even within the same card with all the same specs, different manufacturer's cards perform a bit differently. For example the XFX and HIS cards seem to perform better than the others in most cases. The Sapphire and MSI cards all seem to be middle of the line, the ASUS, AMD and Gigabyte cards seem hit-or-miss. That's not actual analysis, just what it sort of 'seemed like", and it was different per card. Also the IceQ and Frozr cards and such performed much higher H/s than other versions of the same card...however they also sucked up a lot more Wattage in most cases.

From what I saw, from a good manufacturer, with good settings and optimal cooling, a 7850 seems to be able to hit high 300s or just barely break 400. Taking a ~370H/s 7850 at it's routinely reported Wattage of 130, that's a 2.84H/s/W which is very competitive with other cards. In fact, depending on which manufacturer and how your tuning goes, I'd say the 7950 or 7850 are your best cards for power efficiency, with a fair amount of certainty at this point. The 7850 is also almost undeniably your best card in terms of H/s/$.

My Asus 7850 will only do 305@1050MHz with I=14.  The card won't go any faster without crashing the driver.

My Gigabyte 7950 stock (no overclocking) will do just over 500GH/s each, the pair give an average of 1.046GH/s according to cgminer. Far, far better cards, considering I got them both used off the Bay of E for the same price I paid for the 7850 new.

What are the settings other than intensity on your 7850, and how hot is it running?

The 7950 is definitely a good card and 500+ seems totally doable on it by all accounts, but getting 2 7950s for cheaper than 1 7850 is pure insanity. You got an awesome deal.

a 7850 with half the shaders will do exactly half of that *MAX* (or 365).  And when I say max, I mean max..

I have several 7850 they can get a max of 403 and have 5 running in one board. All 5 get 380-385. . I have 2 7870's too. Those cards were hard to get configured. I spent a lot of time messing with them and can get 360 max out of them. I have 2 7970's also they get 660 max
I'd love to know your settings for the 7850, as those will be some of my first purchases. I think as of right now, my numbers lean towards the 7850 and 7950 ben the best investments, they're fairly close on power efficiency and though the 7850 is a more efficient purchase in terms of H/s/$, the 7950 seems like it could put out a lot more horsepower if you set it up right.

One important thing to note about the chart is that a lot of the ranking are very close. So, while you see  1,2,3,4,etc, they may all be within a VERY small range of each other. In the case of some of the ranking, if you look closely, there were even some out-and-out ties. (2 2s in the BTC Rank coloumn, 2 7s in the Overall Rank column, etc).

The problem is some of the hashrates are incorrect.  

A 7970 will do 730 max..  a 7850 with half the shaders will do exactly half of that *MAX* (or 365).  And when I say max, I mean max.. a 7970 at 730 is extremely difficult to hit.

so while I don't have any 7870s, I can tell you 400 is practically impossible unless liquid nitrogen cooled.

New update up, sorry for the confusion...but there was some confusion. Tom's mixed several versions of cards in that are factory overclocked with enhanced cooling units...so they are TECHNICALLY stock - but not really...you can buy them, but it looks like the gains don't make up for the increased wattage.

Also, at least in the case of the 7870, they mixed in a 'Tahiti' version of the 7870 which is *basically* a 7890...it's not really a 7870 anyway, it puts out a lot more hashes/sec...but it eats a ton more power. I haven't included it on the list because for hashing purposes the stock 7870 is more efficient, both in terms of MSRP and Watts.

Also, since I last checked Bitcoin.it and Litecoin.info, someone came through and added a ton more stats to their page, some with screenshots, so I've updated those values where appropriate and included a color tag for the ones I had screenshots for.

I would say I hope this clears up some confusion - but being that it made the overall ranking outcome a lot more scattered, it actually does the opposite...sorry! Tongue

Ok, reviewing some of this, there was 1 card that I mistakenly took stats from the wrong row where they had a crossfire listed, and there's a couple others that were testing "IceQ" version - which are special OC'd versions with amp-d up cooling...you can buy these still - but they'd be more expensive and take more power I assume...and I doubt I'll be able to find all the stats on these, and it'd likely clutter the chart up something fierce...so just cleaning those out at the moment.

I'll have a new version up shortly.

And and there's a "Tahiti" version of the 7870 which is not *REALLY* a 7870 that cranks a hell of a lot harder...looks like it might beat out the 7950...not sure if I'll include it - dunno if I can find enough stats for it.

Well, that's sort of the rub when you're compiling statistics like this. Unless I'm going to get a rig and one of EVERY card, and personally test each myself, I have to base my numbers on whatever reputable benchmarks I can find.

I referenced 3 different sites, 1 of which I know is very reputable and has a very long history of some pretty detailed benchmarking, the other 2 are specifc community sites (wikis) for the respective cyptocoin communities.

I'm not sure why someone would be mis-representing what they're getting with their setups, but the Tom's benchmarks are specifically bitcoin mining benchmarks. Tom's says they've gotten 700 from the 7970 and they say they've gotten 592 from the 7850.

I don't know if you're basing your *MAX* numbers off something math/physics/engineering-based (I would actually love if you were, because I would love to learn more about the actual theoretical limitations here), but Tom's is pretty reputable, and their benchmarks are almost always stock or close to it. So, if they say they got 592MH/s out of a 7850 - I would lean towards believing that...however, based ont he other benchmarks posted on other sites, 592 seems unreasonably high, so maybe they got lucky, or maybe they've got someone in-house that's just super freaking awesome at tuning that card... I don't know.

My end numbers are based on a weighted average of the benchmarks I found though (the listed 416/406 H/s for the 7850), which, from what you're saying might still be a bit too high, though I do see reports of 375-411 from bit & lite-coin mining sites....so I don't know.

I will go ahead and go back and double check my numbers and make sure I didn't transpose 2 benchmarks or something, though.

can you include the 7790 ?!?!
the best cards watt/hash actually are

1) 7790

2) 7850

3) 7950

Ask and ye shall receive. Unfortunately, my research into the 7790 did not turn up as good results as you were hoping for, only showing an estimated efficiency of 2.87MH/s/W on SHA256 , 2.61KH/s/W on sCrypt. If it lived up to it's TDP of 85 it might be a different story, but Tom's clocked it in at 103W on their Kill-A-Watt during a Bitming benchmark. Even at it's listed TDP though, it would hit ~3.18MH/s/W or 2.88KH/s/W, which would put it in the running as a good card, but still not enough to topple the 7850 @ 3.2MH/s/W | 3.12KH/s/W.

The 7950 though, is pretty legit.

I couldn't find any 'trustworthy' sCrypt benches for the 6790, so it's greyed out on those columns because I pulled numbers from some anecdotal benches on a random forum... however, nothing I DID find on that card indicates it rises anywhere near a good level...

Yeah, those sorts of setup issues are the ones I'm finding REALLY hard to find good solid info on. I'd love to know which cards handle multiple best and what tricks you ened to get those working with 6+, considering I want to set up at least a 4 card rig in a week or two with plans to go to 6 at least...Any tips on that?

well i already know that for watt/hash the 7790 wins at over 3.5


the best cards watt/hash actually are

1) 7790

2) 7850

3) 7950

everything else is a really bad choice besides some very cheap ebay 58xx or 69xx cards.


The only problem: The 7790 has its own driver and there are no "tricks" around to get more than 4 or maybe 5 working and its problematic to run them with other 7xxx cards.


A nice idea would be to get a rig running with 3x to 6x 7950 and 2x to 4x 7850 or 7790.



My "dream rig" is actually:

SuperNOVA 1000 G2 1000W
8x pcie power

MSI z77 gd65
8 gb ram
7x pcie slots
ivy celeron total @ 40 watt

total only 400$+


3x 7950 @ 600 watt (undervolted, 620 hash)
4x 7790 @ 360 watt (320 hash)


Total: 3100+ khash/s @ 1100+ watt at the WALL!


BUT getting 7x 7xxx cards working is already very tricky and the the 7790 driver makes this probably impossible.  Cry

very nice chart

can you include the 7790 ?!?!


I could find some info on the 7790, but it wasn't on the other charts, leading me to believe it was not a popular card. Also, all the **90 cards seems to have a trend of being very inefficient purchases, both in H/ss/$ and H/s/W.

I think the usual etiquette I've seen around here so far is to request spare crypto-change for minor tasks you don't feel like doing?

To be honest, I'll probably add it eventually for completeness-sake, but I haven't put it up there yet.

bo122081, this is absolutely perfect Smiley
Thanks you very much!

I tried doing some of my own research, but got stuck on the amount of work it takes v.s. my spare time Tongue
No problem! I was hoping someone would be able to benefit. If I saved you a bunch of time, I wouldn't be against a small donation as this was a couple hours worth of work.

I hope whatever you build with this info kicks much cypto-butt (but not more than my upcoming rig >.>)

Maybe we should try this again.

Hi! I'm new here, I did a bunch of research the other day on different card's benchmarks from various reputable sites as well as the manufacturer's specs and compiled it on a spreadsheet.
I found many of the popular mining website's stat sheets, like Bitcoin.it to be fairly outdated, listing MSRP from a year ago among other things, so I thought I'd share my updated stats sheet.

I hope this helps some people!

If you have any questions about what any of the column labels mean, please feel free to ask!

For example, the Bitcoin.it columns mean that data was gathered from Bitcoin.it, and Litecoin.info from Litecoin.info. Tom's is referencing Tom's Hardware.

Did a lot of work making this, figured someone other than me might benefit and sometimes I'm a nice guy. Enjoy. Smiley


Edit: reversed 2 columns for consistency
Edit2: Added 7790, 6990, 6790. 6890 & 7890 don't actually exist. They were 'leaked' but never actually released.
Edit3: Removed/Changed some mis-reported values, added some values newly added to Bitcoin.it and Litecoin.info, marked which new numbers came with screenshots.


Oh, didn't mention - click on the image for a download link for the XLS spreadsheet through Google Drive. Feel free to leave comments there, as well, as they're enabled.
