ASIC vs GPU mining
#1
ASIC = Application-specific integrated circuit
GPU = Graphic processing unit
 
There are currently many debates regarding ASIC mining (Bitcoins) vs GPU mining (Ethereum, Zcash etc). At Leetpro we like to stay on the forefront of crypto currency trends. We have done extensive research in the current market and have come to several conclusions.
 
ASIC mining in short
A bitcoin machine solves a complex algorithm and receives a reward in the form of a small fraction of bitcoin. The machine is specially built for this purpose and this purpose alone.
 
GPU mining in short
A graphics card solves a complex algorithm and receives a reward in the form of the current crypto currency it is mining. There are many different types of GPU mining currencies. Computers are the main mining machine in GPU mining.

Why we currently choose GPU

Resale value

Graphics cards are already being bought and sold second hand globally. This market is huge locally and internationally and easy to reach via advertising. The key here is to use your graphics card until you have recovered your initial investment and made some profit while there is still some warranty left on your card. This would be the perfect time to sell. If the profitability is still sufficient there is no need to upgrade. The usual warranty on a graphics card is about three years. ASIC miners have a warranty of about three months. They are harder to resell as they tend to be more expensive and fall within a niche market.
 
Multi-purpose
GPU miners are normal computers. As we write this blog, we are also mining. However, we do sell custom rigs that are built to the extreme and harness the graphics cards’ computing powers to keep costs to a minimum. In contrast, ASIC miners are built only to mine Bitcoin and you cannot use it as a desktop computer.

Energy efficient
We have found that GPU mining’s power usage is way lower than that of ASIC miners. Saving power saves money. We have also had success running our rig on a solar-power system. We wouldn’t advise you to acquire a solar-power system for this purpose only as they are expensive, but if you already have one it could probably be utilized. Mining off the grid is possible.

Noise pollution
ASIC miners tend to be loud as a result of the large fan that has to run constantly in order to keep the machine cool. There are many videos regarding this problem on the web. GPU miners also have fans but to a much smaller scale and won’t make more noise than a gaming computer.
 
Upgrade-ability
To upgrade a GPU miner involves upgrading your graphics card. To upgrade a graphics card is easy and usually, you need not buy an entire new computer. To upgrade an ASIC miner you need to buy a new machine completely. Unless you are upgrading on an enormous scale, upgrading your gaming PC with a new graphics card will then also increase your mining capabilities at the same time. Win-win situation.
 
Return on investment is faster
Since graphics cards are more affordable than ASIC miners, your return on investment is faster. Do the maths.
 
The cool factor
An impressive graphics card or two just look so beautiful in a custom PC box. In contrast, ASIC miners could be painted, but the warranty would probably expire immediately. They are not cool.
 
Disclaimer
This information is based on current findings. We constantly research crypto currencies and will keep you posted as we come across our findings. In the past ASIC miners were more profitable but times have changed and competition has grown. These are based on our findings for 2016 thus far.

Do you think the GTX1070s will still be able to offer value when nVidia announces the new 20xx series cards?

1. Do you believe there will be a resell value for the 1070s considering most miners will flood the second hand market with these cards.

2. Do you think the GTX1070s will be able to produce a profit for 3 years or will they be obsolete after the new 20xx series cards?

3. What do you think the future of GPU mining is?

Also interested in what the new AMD RX Vega cards will bring to the mining arena.

My personal view:

1. If the 1070s are still profitable to mine with, the market wont be flooded, it would rather be flooded with 470/480/570/580 cards.
2. Im still mining with a nVidia 680, 690 and a few 7970s and 7990, all still profitable, so i doubt the 1070s will become absolute anytime soon.
3. Alive and well, much more versatile than asic machines, we have invested (and still investing)50% of our profits into gpu rigs.

Thanks for the feedback Leetpro.

Glad to see our thoughts/conclusions are on par regarding the future prospects of the 1070s.

Do you find a difference between the different brands for example EVGA 1070 vs Gigabyte 1070 vs Asus GTX 1070?

What made you choose EVGA over the rest apart from price?

The brand doesnt really make a difference, the EVGA was the cheapest available cards with 3 year warranty at the time
