Lets take a minute to look back at GPU and FPGA Bitcoin Mining hardware. The highest level of FGPAs is silicon chips that are re-programmable. This means that you can configure these chips using programmable routing devices and pre-built logic blocks, especially if you want to implement custom hardware functionality without the trouble of having to pick up a breadboard. The next logical step after the first Bitcoin mining hardware, CPU, was GPU also well known as graphics card mining. Just like its predecessor, FGPA, GPU has dedicated graphics chips that are usually reserved for gaming. In the recent past, GPU and FGPA chips adoption across all Bitcoin mining industries has been seen as lasting cause, because of the following key reasons.

Impressive performance

The performance of FGPA can exceed the computing power of a conventional digital signal processor because it takes advantage of its hardware parallelism that breaks the prototype of sequential execution, thus achieving more per clock cycle. In fact, this has been confirmed by a recent study report by BDTI, a noted analyst and bench-marking firm, that showed that FPGA can provide a processing power of a DSP solution. Faster response times can also be accomplished using two controlling output and inputs at the hardware level.

GPU's OpenCL allows all of its graphic cards to be handled in a higher level, and in a uniform fashion. This enhances the performance of this GPU Bitcoin mining. However, you will have to create your own software on non-OpenCL card, but the process can be so complicated.

Time to market

In the face of increased time-to-market concerns, GPU and FPGA offer flexibility and rapid prototyping experiences. This means that you can try a concept or an idea and confirm it in the hardware without having to go through the long tedious fabrication of custom ASIC design. It is also quite intriguing to note that you can iterate on FPGA and GPU design within hours. Prebuilt functions for advanced control and signal processing are also growing given the availability of high level software tools that reduce the learning curve with layers of abstraction.

Unfortunately Both FPGA and CPU mining is now dead and not effective if you are looking for a good ROI. ASIC bitcoin miners are now producing over 3TH/s speeds. With the current price of bitcoins ASICs devices have created huge ROI and made hundreds of bitcoin millionare ove the last year The future is now in the hand of ASIC bitcoin mining hardware.
