List of CPU Friendly AltCoins

There are rumors about CHC GPU miner
It would not be difficult to "fork"

Hirocoin claims to be GPU coin....  

Hirocoin and Darkcoin use the X11 algorithm. X11 does not give GPUs a huge advantage over CPUs.

All these 11 hash functions have efficient circuit implementation as a design criterion.
So they're all very ASIC friendly, just like SHA256.

If the GPU implementation doesn't have a huge advantage over CPUs,
it can only be due to lack of proper optimization.


This is all the "X11 whitepaper" has to say about X11:

Darkcoin  uses  a  new  chained  hashing  algorithm   approach,  with  many  new  scientific  hashing algorithms  for  the   proof­of­work.  X11  consists  of  blake,  bmw,  groestl,   jh,  keccak,  skein,  luffa, cubehash, shavite, simd, and echo. 
Because  it is more complicated than a SHA256 ASIC implementation,
the use of X11 will prevent the  use  of  ASIC miners for  the  short­-term  to midterm future. It will also allow for a longer period of mining for CPU/GPU users.
GPU   miners   that   mine  with  the X11  algorithm  are  currently  experiencing  reduced  power  usage (up to 50%) and reduced heat generation compared to scrypt.

Is the GPU power savings (compared to other coins) also due to inefficient coding?

im thinking state switches are what is causing the cooler work enviroment for the gpus, you are talking about changing between 11 different hashing algos, so either it has to be compiled as 1 long stream or optimised in other ways

Not a rumor. I updated first post with link.

anyone have a difficulty list of these coins? Would be interesting to see which are profitable

[bbeikoff]

Thanks for the list!!! my cpu is working now!!! 

[YYmeans]

you should list QuickQuickCoin , both CPU and GPU.

Each coin has its own algorithm so you can't compare difficulty

Great!

I am not going to add because the developer is missing. If the dev returns or someone takes over, I will consider.

This made me realize that any coin on the list without an active developer should be removed. I will be making changes. Removed pnut.

Considering about current situation best are X11 to mine for now.

Hi,
the groestlcoin (https://bitcointalk.org/index.php?topic=525926.660) may be also a coin worth to mine.
I've got an E5-1620 and I can mine at 1200 kh/s (~500 kh/s on hirocoin X11).
at this speed it seems to be more profitable (or less bad ) than Hiro or Riecoin

That coin is GPU mineable since day 1. This list is intended for coins that are CPU only or were CPU only in the beginning.

Is there any pool that can be mined through proxy server I have on work several i3 n i5 machines that i can use post here pls.

Found some but no connection.

The original intention of the list was CPU only. As the list evolved, I realized that some coins were still worth CPU mining even when there was a GPU miner available. It doesn't matter to me when the GPU miner becomes available, as long as the CPU is still competitive.

I will check it out.

Look for pools that allow you to connect on port 80. You should be able to connect without proxy.

Isn't Primechain/Primecoin the only hashing algorithm that GPU is no faster than CPU with current software?

The jury is still out on Cuckoo Cycle, as little effort has been put into GPU implementations.
A direct port of the current latency-bounded CPU implementation performs
much worse than the CPU one, but that's not saying much...

Not anymore.

Let me know if you need a tester with 5830, 6950 !

Cuckoo Cycle isn't used by and coins yet, is it?
