Hello  community , unsure where to post this, but appreciate the help.

How do u know if a CPU is good at mining before u buy it ?
I find this a challenge, where do u check this?
www.cpubenchmark.net is not a good indication of this i find, or maybe i dont know what to check?
I really want to know because i am told you can buy a really cheap CPU like an AMD operton or INTEL celeron and it can be as good good as an i3 or xx phenom.
Really bizzare, but i have tested this theory and it seems with the 5 computers i have tested, the CPUs on cpubenchmark  show different results to real actual mining.
For example mining against AEON.... AMD X4 860K mines at 115 hashes/second  and the i7 2600K mines at 210 hashes/second  BUT on cpubenchmark  it is not the same stats...
Another example, using an Intel E6300 u get 45 hashes/per second and this is almost half of the AMD x4 860k and they are years and years apart in manufacturing and even speed...
But why only almost 2.1 times faster, it just doesn't make sense to me.
Therefore , for me i need to know what or where to check this information and what to check for , can i use www.cpubenchmark.net as this gauge ?

I really want to know this more clearly.

Thanks

Why are you even trying to do CPU mining? CPU, GPU, and FPGA mining on Bitcoin is completely useless, you won't earn anything as the hash power is way too little. Even with Altcoins, CPU mining is still fairly useless as basically all altcoins use algorithms that are easily GPU mined. You shouldn't try CPU mining, go with GPU mining instead.

Agree with achow101. CPUs are useless for mining BTC.

If you still looking for info check these two pages: Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison) and Non-specialized_hardware_comparison (https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison) (here you can find CPUs)
