Samsung has just turned 40 Galaxy S5 smartphones into a large Bitcoin mining machine

It's no surprise that most smartphones launched these days are more powerful than many computers released several years ago. So, why wouldn't a handful of smartphones be as powerful as one of the modern PCs worth more than $2,000?

Well, it appears that you only need eight old Samsung Galaxy S5 smartphones to be able to mine Bitcoin the way a desktop computer does. In fact, the smartphones are more power-efficient at Bitcoin mining than a similarly powerful PC, Samsung claims.

As part of its “Upcycling” initiative, Samsung has decided to show other smartphone companies that even two-year-old handsets remain useful and can be turned into something new, thus prolonging their life.

For that purpose, Samsung built a Bitcoin mining rig comprising of 40 Galaxy S5 smartphones. The entire mining machine runs on a new operating system specially developed by Samsung for this “green” project.

Besides the Bitcoin mining rig, Samsung also showed a couple of other repurposed smartphones and tablets at its developer's conference in San Francisco. Among them, an old Samsung Galaxy Tab tablet turned into an Ubuntu-running laptop, and a Galaxy S3 programmed to monitor a fish tank.

So, yes, there seems to be life after death even for old smartphones that have reached their EOL (end of life) status.

But it’s just such a bad bitcoin mining rig. They were better off as phones. If you want to do something with them load them with stock android and recycle them as phones.

Why are they comparing it to a CPU? They're terrible at mining. Most desktop GPUs would run circles around this rig.

Both are bad at bitcoin mining. Bitcoin mining is all about ASICs now. GPU do good at ether and CPU for XMR(monero).

It's funny they pick phones with AMOLED screens to display things on the screen forever (pretty much)

It doesn't need to display anything, even most bitmining rig didn't even connected to monitor, It just need monitor for first setup (and after power cut)

i7 2600? Who the hell using this old processor to mine bitcoin? People use ASIC for bitcoin, and GPU for etherium. CPU is just ineffective
