Cryptocurrency mining on X11 algorithm. The use and comparison of CPU and GPU for mining on X11 algorithm.

cryptocurrencies on X11 algorithm, X11 cryptocurrency mining Let’s perform the settings of cryptocurrency mining software on X11 algorithm on GPU and CPU, let’s check how it works and make some conclusions

For CPU, OS WIN7 × 64
We use two versions of programs that run on processors with X11 algorithm. If your processor supports AVX / AES instruction sets, use cpuminer-1.3. If not, use cpuminer-1.2c.
Cpuminer-1.3 has several miners for different processors, you need to choose one that is suitable for your processor.

Below is an example of processor settings:
1. Intel Core 2 Duo E7200, 2533 MHz
2. APU A6-6400K, 3900 MHz

To view supported instruction sets we used Everest.
1. According to specification you can see that there is no support for AVX, or AES. Download the cpuminer-1.2c. Unpack the archive and create a batch file in the folder with the following data:
minerd-a X11 -o <host>:<port> -u <user> -p <password>
Run the batch file and get on the Intel Core 2 Duo E7200, 2533 MHz processor: ~ 76 kHash/s (~ 38 kHash/s per core).

2. For processor APU A6-6400K, 3900 MHz download the cpuminer-1.3. Unpack the archive and create in the folder a batch file with the following data:
minerd-bdver1 -a X11 -o <host>:<port> -u <user> -p <password>
Here you need to use the core minerd-bdver1 which supports AMD processors.
Run the batch file and get on APU A6-6400K, 3900 MHz processor: ~ 100 kHash/s (~ 50 kHash/s per core).

for GPU use sgminer 4.1.0, OS WIN7 × 64
sgminer 4.1.0, read more info here
in the settings you must specify the core -k darkcoin (-k darkcoin -o <host>:<port> -u <user> -p <password>).

Below are some grphic cards and their settings as an example of what you can get:
We used sgminer 4.1.0
AMD Radeon HD 8470D(AMD A6-6400K) (—gpu-engine 800 —gpu-memclock 800 -I 18) — 0.2 MHash/s;
AMD Radeon HD 5870(ASUS): (—gpu-engine 900 —gpu-memclock 1100 -I 20) — 1.27 MHash/s;
AMD Radeon HD 7970(MSI) (—gpu-engine 1050 —gpu-memclock 1690 —thread-concurrency 24000 -I 20) — 2.14 MHash/s;
AMD Radeon R9 290(Ref, BIOS от Stilt) (—gpu-engine 980 —gpu-memclock 1450 -I 20) — 2.4 MHash/s;

In these examples we did not intend to find the best performance.

The memory and processor (GPU) temperature is significantly lower comparing to Scrypt algorithm.
The description of X11 algorithm as processor-friendly is not entirely correct, although average cost equipment was used .
