who cares about windows ⌠only people who are too lazy to install free stable and secure linux LOL⌠why do people want to use an OS with backdoors out the ying yang
3x more people have been working on Zcash GPU miners for 2x longer than the 2 people working on CPU miners, and I canât confirm that the RX480 or 7950 is a better buy at this point than CPUs. Yaâll are assuming GPUâs will advance from 50 Sol/s faster than CPUs.
The other developer was saying 120 Sol/s for the GTX1070 ($400 in similar price comparison basis) for a 150 W GPU (1050 Watts for 6x system, 720 Sol/s). So that would be a little cheaper than CPUs at 1/2.5 the electricity.
The 7950 appears to be $75 ebay (for direct price comparison to desktops, i.e. youâve previously said it was lower in which case desktops would be lower with similar bargain hunting skills) and uses 225 Watts. You previously posted 25 Sol/s for this, so Iâm not sure jumping to 100 Sol/s is possible (again, this reasoning assumes a more efficient CPU miner will not come along also).
A detailed article says itâs gross wattage is 150 W per card in an optimized system which means 900 Watt system giving 300 Sol/s. So 900 Watts for 300 sol/s is same as current CPU miner.
Initial price-wise for 6 of these giving 300 Sol/s, I see GPU miners claim a system of $200 cards would cost $1700 because 900 W power supply is not cheap plus overhead hardware. This is slightly less than $7 per Sol/s for CPU in comparable pricing. Thatâs slightly less expensive my CPU options. This assumes he can get 50 Sol/s on the RX480.
You helped make the challenge so I had to do the work to dig up the numbers.
My point in all this is to try to show developers they can make Zcash a very different coin, in accordance with their stated objectives. There is such a strong belief that GPUâs are better at mining, that itâs a hard belief to go against. I posted back in July it looked like GPUs would not be able to do better than being 2x more expensive in electricity. This was based on looking at about 10 papers showing a long history of not being able to get GPUâs to be as efficient as CPUs at sorting. The GPU development speed almost caused me to start selling my desktops, then tromp and xenoncat changed things. BTW the desktops have not dropped in price in 6 months because Mooreâs law has stopped. (I estimated 2015 was the limit for mooreâs law back in 1992 based landauer and bennettâs work which is based on the speed of light and the entropy (heat) released from changing the state of 1 bit. Assuming a synchronous clock, constant voltage, and non-quantum. The limit is not based on the minimal size of traces.)
You need to realize that your numbers will change tomorrow, next week, next month.
Honestly this entire ZEC can end up crashing completely and nobody will be mining it.
With GPUs you can mine ETH at least. If power consumption is a big issue in your area then you shouldnât be mining in the first place because eventually Profit = Energy Consumed and only those with free or cheap power will survive
