Mining machine graphics card can play games
The miner is better
-
the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge
-
mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />
for mining, all mining machines do not shut down for several months. And the graphics card is always full of work, there is no time to rest
some of them are still used in overclocking mode, which is much more intensive than the personal home graphics card used for several years.
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.

mining is to split the hash operation into several sub operations. A card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times
in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics cards, such as gtx750ti / 750, came into the market, the mainstream currencies could not dig out anything with graphics cards. Therefore, few people use n-card mining.
in the next generation of procts, n card will further restrict the use of game card as computing card, and the division of proct line will be more strict; The driver and architecture of the game card will become more unsuitable for mining
as for AMD graphics cards, generally speaking, mining will not be strictly restricted, because the sales volume of AMD graphics cards is lower than that of NVIDIA graphics cards. Mining customers are also customers. It's a little more if they can sell more. AMD's attitude should be relatively open about what users use to do.
