I'm doing 2150MH per 750TI at default clocks speeds on my Gigabyte 750tis right now. Chris and Chris have said they have a version doing 2.8MH that will be released soon.  They also have a new version of Groestl that is far better also, but no eta on that one.  I can't wait to see what they can do with higher end Maxwell cards that will be released later in the year. 

Remember this cheap $150ish 750ti card competes with 270x on price but eats 290x on performance which is utterly fantastic (if you own a few of them)! Smiley
They rewrote groestl and X11 targeting Maxwell's strengths. Current groestl implementation for OpenCL is using tables which (my guess) is good for older cards but limits newer GCN generation...
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.

That sounds about right.  I believe X11 targets nVidia strengths only so they (C&C) released the source for this.  Groestl speedup I believe is more programmer then card functionality which is why they haven't made a release for this as it could be "copied" giving 280x/290x a big boost in speed.

That is why I alluded to the fact that some algos could be further optimized on AMDs.

The AMD camp needs a person or two of comparable strengths to C&C&D.  This isn't a slam at all on AMD hardware as it's basically better but nVidia did it right with CUDA which is really a lot better for programmers.  So now that a couple of really good programmers (Chris and Chris and occasionally Dave) have started pushing the boundaries of what CUDA offers to miners we are at a "pass". 

Is it better to have better hardware with lackluster software performance (in the hopes of better software) or "lesser" hardware with better software (which also requires less energy)?

Tough call but for the next month or two it would seem like nVidia/C&C owns the GPU market.  If nothing is done software wise from the AMD camp then nVidia will really run away with things in 6 months or so when nVidia releases higher end performance cards based on the Maxwell architecture with more cores.

Like I previously said I'm about 50/50 on hardware between the 2 camps so I'm not a hater but nVidia is looking really good for any new purchases right now.

mined X11 Nvdia is better than AMD?

Yes.  The 750Ti can get 1.8-2mh or even more on X11 for only 50-60 watts.  On scrypt it did between 300-400kh.  That is 5-6x the scrypt mining rate.  My R9 290s do 2.47mh on X11 which is roughly 2.9x what it got for scrypt mining and it uses ~180 watts per card.

Basically the 750Ti is 3x as efficient as the R9 290 at current X11 mining rates and power consumption for those cards.

2.47 seems very low for the 290, should go higher like 3MH/s +

I'm about split 50/50 on AMD and nVidia at the moment but I'm not buying any more AMD GPUs at present.

Makes me want to sell off my AMD cards and replace them with Maxwell cards.  The downside however is that ccminer isn't as "polished" as cgminer or variations of it from an interface or API standpoint.  Maybe one day when they get bored with new algos they will work on these things.

C&C are really ringing out the performance of the Maxwell 750ti cards.  I'm sure that more could be done on some algos for the AMD side of things if the right person/people were involved.





woah 2.8? insane, they are starting to optimize for x11 algo really well, you can tell that from the consumption

2.47 seems very low for the 290, should go higher like 3MH/s +

280x does about 2.2MH
290 does about 2.5MH
750ti does 2.15MH (soon 2.8MH)

On my rigs anyway.

it should go up to 27-28MH/s at least, because in scrypt a 290 is about 20% than a 280

do you have an optimized version of ccminer? I want to ddl it. I meant 2.8 MH/s with 750ti. Smiley

While sgminer is lagging around, someone already tried to earn money from the unoptimized x11 code for AMD card
https://bitcointa.lk/threads/ann-x11-x11-darkcoin-gpu-miner-40-faster-than-sph-sgminer.316575/
280x to 3MH/s, and he asks for 2% mining fee, come on!!!!

Perhaps gathering a bounty so that he can release the code would do the trick.

Yeah, it could be a scam. But it shows that an x11 optimization is much needed for sgminer now.

I tested it with 280x, 7850 and 5970.
With 5970 : no optimisation at all
With 7850 : 45% more hash (1 MHs => 1.47MHs)
with 280x : 37% more hash (2.33 => 3.2MHs)

So, i don't like at all the fee thing, i preffere to make a 0.15 btc donation, but it show there is room for optimization !

Dont think its scam, girino made a gpu miner for metisicoin - probably based it off ypools model of 2% dev fee for custom miner. mts is dying soo more profitable hitting x11 as it seems to be the flavour of the month atm.

I mine therefor I am Smiley - WIN : WcLLYcZfHQAMMVwiaAtMECZQh1YfCPw88g

it`s a scam (IMHO): I didn`t get any accepted shares from my pool, miner is digging only for creator  Angry
or may be my pool doesn`t like this software  Grin

6970 - 18% more (1770 vs 1500)

Had you tried
Code:
-g 2 -w 256  --shaders 1600 --thread-concurrency 8000
on 5970?
On older Radeons optimal seems to be threads==shaders*5

PS: It was mining OK at drk.coinmine.pl
30% up on 5850 - 1300KH/s up from 950KH/s

PPS: Changing to -w 128
6970 -  2050KH/
5850 - 1330

OK, i made some longer testing..

I'm mining darkcoin for testing. The diff is between 2000 and 3000.
I am mining for the dev (2%?) and for me (98%)

But, strangely, when mining for me, on my pool, with my worker (infos shown by sgminer),  sgminer claims i have found a bloc ! two times !...with 154 and 924 for best share... with a >2000 diff, it's not possible..so it's not on my darkcoin pool, as shown, but on dev pool

Did the dev disguised more fee than announced ? (so, is it a scam ? looks like)

edit : also, i saw it mining on my pool (darkcoin) but with an other block than normal shp-sgminer on another computer, strange ?

personally, I would avoid using it until it's opensourced, which probably won't happen because people will rebuild it without the fee asap.

Don't bother with this binary.

The "speed up" is all in the client display.  You will find you actually generate far less shares on any pool.

I tried it with 4 different pools and got the same results. Client shows higher MH rates but ALL POOLs show far less shares accepted.

JUNKWARE!

Hi Guys!

Just a quick question. Im mining DRK on x64 Win 8.1 with the sph-sgminer.

I only get rejection. Do i need to install another driver or this AMD SDK to solve this problem?

i have a ATI 6870 with latest driver and run at 20kh/s
