760 graphics card 2G mining
the architecture of a card is different from that of N card. AMD is a brute force heap stream processor without considering the operation efficiency, while NVIDIA greatly improves the operation efficiency, but the number of stream processors is small. The final result is that both sides have their own advantages, and they are almost tied in all kinds of 3D games. In general computing applications, n-card has the upper hand, but the leading advantage of n-card may not be the problem of efficiency, but the software optimization and program development are in place
bitcoin digger adopts SHA-256 algorithm, which can perform a large number of 32-bit integer cyclic right shift operations. This operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate (2 Shift + 1 add) in NVIDIA GPU, This one alone brings amd an additional 1.7x computing efficiency advantage (about 1900 instructions to perform SHA-256 compression operation, rather than about 3250 instructions from NVIDIA)
in this way, AMD's high floating-point computing power and algorithm efficiency advantages make the performance of AMD GPU in password cracking and bitcoin mining more than three times that of NVIDIA GPU!
I read too much news
for bitcoin mining configuration, the CPU requirements are extremely low, as low as those of the old computers ten years ago, the graphics card requirements are extremely high, and the higher the efficiency, but mining is the world of a card, and the N card is only half of the efficiency of a card, and the electricity charges can not be returned.
amd GPU can be realized by a single hardware instruction, while NVIDIA GPU needs three hardware instructions to simulate, This one alone brings amd GPU an additional 1.7 times of computing efficiency advantage

running points are close to
! Dx12 fiasco
! No cost performance! 660 or R9 270 is recommended
No, most games don't use 2G video memory
First of all, let's look at a set of data. Gtx760 is the core of gk104, with a bit width of 256bit. Gtx660ti is castrating the bit width party. Unfortunately, gtx760 reces two groups of SMX, and the stream processor shrinks again. Although the bit width remains unchanged, the stream processor and texture unit are reced
there won't be a big gap between gtx760 and gtx660ti in the game, most of the games are slightly ahead of gtx660ti, and in indivial games, such as battlefield 3 under 1080p and biochemical crisis 58xaa gtx660ti are slightly ahead
considering that the performance of hd7870 is slightly worse than that of gtx660ti and the price is basically the same as that of gtx760, gtx760 has the advantage of performance and price in hd7870 and gtx760
compared with hd7950, gtx760 may have some disadvantages, but the difference is not too big. After all, the pricing of the two is different< br />
