CPU mining of a coin is only inefficient if the difficulty is extremely high.
Some in this thread are showing extreme ignorance by comparing CPU mining of LTC, a coin with 400+ difficulty, to CPU mining of YAC, a coin with 7+ difficulty
In very simple terms that I hope everyone can understand It takes fare more kh/s right now to mint a single LTC , due to difficulty, than to mint a single YAC
You can't compare a coin that is mostly CPU mined, low difficulty, to one that is mostly GPU mined high difficulty. Apples to Oranges
What you can compare is total joules needed to mine a YAC v to mint an LTC. At present difficulties, I think YAC wins that battle because - in part - it is so new

What was the hash rate of your 7950 for scrypt+chacha/kekkac(32,1,1) again? 
~650.I assume you meant ~650kH/sec for scrypt(1024,1,1) rather than scrypt+chacha/kekkac(32,1,1)?
What was the hash rate of your 7950 for scrypt+chacha/kekkac(32,1,1) again?
I just mine an actual, profitable alt coin, LTC...And my hash rate is 550 KH/sec
Kinda an apples vs. oranges comparison then, eh?
Might that be equivalent to me saying my Radeon 5850's mine SHA-256 coins at 350MH/sec vs. your 7950 on scrypt at 0.55MH/sec and declare the 5850 the winner by several hundred times?
4 Xeon CPU's, to barely hit the hash rate, of a single 7950....That is certainly cost effective 
What was the hash rate of your 7950 for scrypt+chacha/kekkac(32,1,1) again?
2x Intel Xeon E5-2670 = ~750.
I just mine an actual, profitable alt coin, LTC...And my hash rate is 550 KH/sec
Because you can only mine 1 at a time, yes?

And, last I checked, you can't shove 4 CPU's into a single tower, so, we are talking an entire PC for each CPU...
That's not entirely true. It would be true if you said you can't shove 4x consumer-level i7's onto a single consumer-level motherboard. Finding a motherboard that'll fit a normal ATX case and holds 4 Xeon CPU's is not particularly difficult.

When it comes to wanting a lot of CPU power, it's hard to beat the IBM BladeCenter platform. There are already photos of part of my BladeCenter server farm in some of the Yacoin threads. You can cram 28 Xeon CPU's (2 per blade server) into each 7U of rack space, and currently you can do it at a cost of around 50% what you'd pay to set up headless i7-2600k PC's for an equivalent amount of CPU power. On one hand you have consumer-grade gear with PSU's that'll fail if you look at them funny, and on the other hand you have carrier-class equipment that'll run for years and years hands-off without a single hardware problem, yet still cost less than the consumer crap.
A single 42U rack (standard 7' tall 19" rack) can happily support 84 IBM blade servers with 168 Xeon CPU's, taking up a whole whopping 6 square feet of floor space in the process.
do you have any idea, how much money can people make and their kids dont have to starve or rob a old lady?
heh heh heh
Do you guys have any idea, how much electricity it takes, to run enough servers at %100 load, to make it worth while to mine these coins? Just saying, not very green...Not to mention, there's gonna be a lot of unhappy parents, when they get the power bill this month lol
Do you have any idea how bitcoin started out?
Yes, in a savage, dark age, of Pentium 4's, and 32 MB GPU's....Do you want us to go back to those times? Shall we live in caves, and club our women too??
So in other words, you have no clue. Pentium 4's and 32mb gpu's, really? LOL!
It was an over exageration

B) YAC is extremely vulnerable to an 51% attack by someone who writes a gpu kernel and has a decent rig
YAC generates coins by PoW and PoS. That someone would need to own 51% of all the Stake. Kinda self defeating.
2) Actually, attacker needs only 25% of current active stake weight.
But it's correct that it's almost impossible to overtake PoW+PoS chain using pure PoW chain.
The forums are getting really quiet, as Yac value drops...lol

Actually, for the ammount of hashing power in a single 7970, you would need multiple CPU's to match it, ergo, you need more power to run the equivilent number of cpu's, then a single GPU
There is a reason research centers like switching to GPUs. It is cheaper per petaflop

The only reason why people mine this coin is because it is CPU only and everyone and their dogs have CPUs.
To deliberately handicap the GPU base is a terrible idea IMO. You're only making the network susceptible to 51% attack from botnets.
Isn't it what all cryptos are striving for is to have more security by increased hashrate?
I guess this coin is appealing to high school kids with plans to capitalize on school computer labs?
