NaN.

This makes more sense than most of the guesses out there. Thanks for for sharing this answer with us.  :)

wolf, I don't get what you are trying to say. Can you put in layman terms please?

But that is actually nice on the hardware. Less wear and tear.

The dark coin wiki says this about it.

Is X11 cooler in GPUs because it's inefficient?

Not necessarily. Bitcoin mining in GPUs (SHA256) requires less energy than Scrypt and yet no-one claims that SHA256 implementation is inefficient – it's just that there are differences in how each hashing algorithm uses the hardware.

Regarding X11, apparently the “gaps” in the chaining sequence, as one algorithm is hashed with the next algorithm, provide for a “breathing” space or “lag”. An alternative explanation is that certain algorithms (out of the 11) are just slow when processed by a GPU and thus slow down the whole process. The hashing of a chain can only go as fast as the slowest algorithm of the chain.

There should be some level of optimization possible in some of the hashing algorithms that increase the hashrate and energy consumption in future versions of the GPU miners. Groestl in particular is considered to be improvable.

no shit i said that when it came out and they ran around advertising that and you all argued with me endlessly LOL

I told you so ;)

PS:
Put Blocknet in your topic title if you want people to read this ;)

The world is tuned in and we need up to the minute late breaking Blocknet-gate scandal coverage !

PPS:
I can post 50 quotes of me saying that 6 months ago too if need be ;)
thanks for proving my rightness though..
I am always right, come to terms with it  8)

What about the X7 that Cryptonite uses?

well i was impressed by your work though good job :)

and X7 i have no idea LOL

JHA aka: Jackpotcoin uses mix of 5 .an X5 algo of sorts
and it is less of heat draw than X11 too

any opinions on lyra2 that vertcoin is supposed to be coming out with?  they claim it will be easier on the cards than scrypt ... wonder if it has this compromise

P.S.  I'm picking up some jackpotcoin just 'cuz i love you spotniek

In other words - your closed sourced miner will be much more efficient than the open source one huh :P

Nothing wrong with that.  Just out of curiosity why do you normally sell your miner or mine yourself instead of releasing a closed source with a %?

Great write up and discussion great stuff.

Nice write up OP. Btw Spoetnik, you're wrong most of the time.

Is it the same for FRESH algo?

Oh ok. It runs cooler and acts a lot like x-11.

Hehe I've read in many forums x11 runs cooler cause it sucks at hashing.  I'm surprised nobody has bothered to fix this until now...

Or perhaps it was such a large job to do properly it required some long term planning.

Do me a favour mate, "basically the same - the extra wave in flight helps hide memory access times, causing it to be faster", can you explain why the extra wave in flight helps hide memory access times?  Why is hiding memory access times a good thing for speed?

OK so why is this so? Because the GPU schedules other waves to execute while the memory access is going on.

Why would it bother scheduling waves if it can operate more efficiently doing things a different way?

decent guide !

Are you saying X11 is better than other coin protocol?

Agreed. Enjoying it so far. :)

i don't open my mouth with out the ability to prove it 99% of the time and you all make vague snotty little insults at me.. as usual
and being an obnoxious asshole has no bearing on whether i am right or not sweety.. go back to flogging shit-coins and Trolling prick.

sad tons of you out there are mentally challenged idiots that could never master the concept of staying on topic on a forum.

click topic.. see Spoetnik say something.. insult him and then leave.

and i am the loser ?
mmmmm hmmmmmm  ::)

I can't even describe with words how far you are out of your league Come-In-Behind
..scurry off or i will give you the infamous and legendary Spoetnik Treatment !

Your only reply should be thank you, for me giving you my opinion (The correct one)
The words of Spoetnik are a gift to the Altcoin scene and you all should feel privileged you even get to read them !
..your welcome now be quiet i am the smart one here !

@UnicronFarts
I think they are pretty cheap so prob not a big risk eh (picking up some JPC coins) LOL
I have seen crappier coins go the moon hahahah

whats up with the furry wallpaper man

it was new to me... I went wtf?


Nice analysis, the thought I'd like to add is that even if you had the most possibly efficient x11 implementation and it still runs cooler than, say, scrypt, then you should still prefer scrypt over x-whatever. If the most optimized implementation is cooler, you are wasting power in keeping all the system working compared to scrypt, so you get a worst "network security / watt spent" ratio.

nicely explained Wolf0, thanks.

Very nice write up.  I've always wanted a good explanation.  Thanks.
