The question is, how fast if Bitcoin mining is done with CPU?

Its impossible to mine fast on CPU currently.
To put you a perspective.
CPU  can mine with speed 1
GPU  can mine with speed 10
ASIC can mine with speed 100

;) You never beath GPU with CPU, not talking about ASIC. Gap is too wide.

it's all depends on your hardware obviously,
but it's not really fast if you compare it using GPU aka VGA or Others,
For example :
A CPU core can execute 4 32-bit instructions per clock (using a 128-bit SSE instruction) or 8 via AVX (256-Bit), whereas a GPU like the Radeon HD 5970 can execute 3200 32-bit instructions per clock (using its 3200 ALUs or shaders).

so based on this you should know how much the gap between both of them right ?

in conclusion,do not mining Bitcoin using CPU right now because it's no longer profitable,let alone CPU even GPU/VGA no longer profitable right now.
so buy a miner if you want to mining Bitcoin such as ASIC,BITMAIN Ant Miner and Others

Your numbers are way off.

CPU : 1 (50 MH/s)
GPU : 20 (1000 MH/s)
ASIC: 200000 (10000000 MH/s)

Don't waste your time, CPUs have long left the mining scene with Bitcoin. Is ASICs you want.
But not even ASICs unless you have a lot of money to spend on hardware.

It is also very risky in terms of investment.

Bitcoin is practically impossible to mine on a CPU. However, there are other coins, you can still mine Monero if you're on a pool for example.

Mining bitcoin with CPU is not a good idea because the primary device that you will be using is the GPU or graphics card because they have the capability to solve the math problems easier and faster so you can get your reward which is bitcoin faster enough than the CPU. It is also risky to use your CPU and it can damage the lifespan of your CPU because they are all maxed out when they are being used to mine bitcoin.

thanks for the information
But what is the Mining difference between using CPU / GPU and ASIC?

If you mine with CPU/GPU, you might never get a block at current time as the difficulty is rising with advance miners on mining.

Mining bitcoin with CPU became completely meaningless years ago, even using pools. I started mining in the first half of 2011 and even then solo mining with CPU was nearly impossible and mining pools became widespread. Now even GPU mining does not make sense.

there are some altcoins mineble on GPU. until they are not enough popular to get their own asics :D

Take a look at a calculator.

https://www.nicehash.com/?p=calc is a simple one

A basic CPU may get you 2400 satoshi a day, maybe
A top of the line GPU may get you 34000 satoshi a day (X10)
An antminer S9 is 410,000 satoshi a day.

You'll also notice the ASICs take up far less power.

I do question the CPU result, I doubt it could keep up fast enough for a pool to even recognize it.

Please dont try to Mine with CPU. Last thing you want is melted Laptop/Desktop. Lot of heat is generated during mining. Also, Mining is no more profitable. So better buy bitcoin.

you will generate 1$ in month ......

try gpu... or asic...

now , nobody use cpu to mining bitcoin because you waste 100000 years to mining 0.01 btc ,
good luck your idea.
ASIC is best choice

Mining with CPU is outdated and I don't know if there is even a single alt-coin (reputed) available for CPU mining or not. Do not waste your time on those ads (you might see on Facebook mostly) claiming to give you some Bitcoins against your CPU GHz. Even cloud mining is no more profitable these days. Bitcoin mining is a serious business now and we should leave it for them who consider it in that way.

As above, you're around 8 years too late to mine competitively with a CPU.

Other alt-coins are more suited to being CPU mined, but even then, GPUs are far more efficient.
I would suggest GPU mining with NiceHash for a beginner (it automatically mines the most profitable currency, then trades it for btc), or just spend the cash you would've spent on the electricity and depreciation of hardware to buy whichever currency you like.

Avoid Sterling though - hear that's going to tank with something called Brexit happening...  ;D

ASIC  is best choice now
GPU is low speed now

CPU Mining is definitely not profitable since logn time. The only way you can mine Bitcoin is with ASIC Hardware

Is there a difference in what type of CPU you use? like faster/slower CPUs with more or less pwr usage? does that make a difference in how fast you can mine?

CPU mining sadly died a long time ago.. but to answer your question, yea there is gonna be a difference if you use a newer (therefore faster) CPU with a lower power usage
than an older (slower) CPU that also uses more power. If you want to mine, I would start with a cheap ASIC USB stick...  I have 5 Antminer U2+ sticks, which are cheap ASIC USB sticks and together they do roughly 9 Gh/s... If you don't want to spend anything right away, I still suggest using a GPU rather than the CPU.

thanks for the info, but what about the GPU? same as the CPU? (like newer better ect..) idk about ASIC yet  :-\  the pwr usage is high. was wanting to use a low pwr CPU for starters,
what do you recommend?

Well if you have to buy a CPU, you mind as well get a ASIC stick really.. I mean just took a quick look on amazon and found a decent one (Rev 2 GekkoScience 2-Pac Compac USB Stick Bitcoin Miner 15gh/s+) for 90$ ( 32-.35 watts per gh)as for the GPU.. A Radeon RX 470 has a modest hash rate of 24.0MH/s. Its power cost per day is exactly the same as the Radeon RX 480 at $0.4320. Its cost per MH/s is $9.13, giving it a return per day of $1.15 and a return per year of $418.16. Radeon RX 470 will cost you $219. As you can see the GPU would use way more power than the ASIC sticks... and the ASIC generates more /sec. If you gotta spend money for a cpu you mind as well buy ASIC sticks.

Ok wow lots of "tech" info  :o
looks like I need to do more reserch haha, but from what I understood, yea it does seem like starting with a ASIC usb stick would be best in my situation (dont have to buy a new rig for that right) could I just plug it up in my old laptop?

lol yea by all means do your own reserch.. and yea you can plug it in your old laptop, usb stick dosent tax you CPU so can still go on and use your laptop as you would usually  ;)

A snail vs. a slug. Either way it is too slow.

You can invest in CPU mining, but not to mine BTC. There are other coins if you actually want to profit from your powerful CPU. Back in 2012 it was already hard to impossible to mine any bitcoins with a CPU. Back then the most efficient were FPGAs, the early mining chips. A year later ASICs came out and an era of dedicated miners begun. Sounds like quite a story, right?:D

You have made me curious, how long would a I5 or I3 survive if someone started mining with them

Also I have an IT friend that jokingly told me he is gonna get all the shitty gpu less pcs in my office to mine ETH how long till everything burns down?

For many years. Mining doesn't degrade a CPU, it keeps it at close to 100% load the whole time, but these chips are made for it. They just need proper cooling.
Unfortunately if you mine with low grade processors you'll pay more for power than you'll be able to mine. If you had a mainframe and could configure it to mine a CPU coin, you could bring in some serious money ;)

CPU for example have 2 cores that two cores need to solve math algorithm and problems when mining ..
the GPU have more cores so you can mine faster in a good GPU example 1080 Ti
the next one is the hardware dedicated only to make bitcoin or to solve faster math problems...
BE aware that the eletricity will be high and your bill may increase a lot :)

CPU coins are very rare but there are a couple. Most altcoins also will use asic now but there are some gpu coins like eth because of the difference algorithm.

The feeling is like your a turtle and you are racing with a horse. So you will mine at just speed 1 so lower income when you use CPU I recommend use a Antminer D3 :)

As i just started a Forum on building rig for bitcoins... I guess it will much and the return of investment is harder thab i expected... Considering the 1000 watts power per hour.... Thats huge... And as i just read... It is already dominated by ASIC.... i just have to divert to find ways to earn ....
