NVIDIA Coin Mining Spectacle Increases with Maxwell and GTX 750 Ti, PC Perspective

Spil wij have talked about on several different occasions, Altcoin mining (anything that is NOT Bitcoin specifically) is a force on the current GPU market whether wij like it or not. Traditionally, Miners have only bought AMD-based GPUs, due to the voorstelling advantage when compared to their NVIDIA competition. However, with continued development of the cudaMiner application overheen the past few months, NVIDIA cards have bot gaining spectacle ter Scrypt mining.

The largest show switch we`ve seen yet has come with a fresh version of cudaMiner released yesterday. This fresh version (2014-02-18) brings initial support for the Maxwell architecture, which wasgoed just released yesterday ter the GTX 750 and 750 Ti. With support for Maxwell, mining starts to become a more compelling option with this fresh NVIDIA GPU.

With the fresh version of cudaMiner on the reference version of the GTX 750 Ti, wij were able to achieve a hashrate of 263 KH/s, astounding when you compare it to the voorstelling of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.

Spil you may know from our utter GTX 750 Ti Review, the GM107 overclocks very well. Wij were able to shove our sample to the highest offset configurable of +135 MHz, with an extra 500 MHz added to the memory frequency, and 31 mV bump to the voltage offset. All of this combined to a

1200 MHz clockspeed while mining, and an extra 40 KH/s or so of spectacle, bringing us to just under 300KH/s with the 750 Ti.

Spil wij compare the spectacle of the 750 Ti to AMD GPUs and previous generation NVIDIA GPUs, wij commence to see how awesome the vertoning of this card stacks up considering the $150 MSRP. For less than half the price of the GTX 770, and toughly the same price spil a R7 260X, you can achieve the same voorstelling.

When wij look at power consumption based on the TDP of each card, this comparison only becomes more epic. At 60W, there is no card that comes close to the spectacle of the 750 Ti when mining. This means you will spend less to run a 750 Ti than a R7 260X or GTX 770 for toughly the same hash rate.

Taking a look at the spectacle vanaf dollar ratings of thesis graphics cards, wij see the two top performers are the AMD R7 260X and our overclocked GTX 750 Ti.

However, when looking at the show vanaf watt differences of the field, the GTX 750 Ti looks more extraordinaire. While most miners may think they don`t care about power draw, it can help your bottom line. By being able to buy a smaller, less efficient power supply the payoff date for the hardware is moved up. This also bodes well for future Maxwell based graphics cards that wij will likely see released straks ter 2014.

To illustrate this example, wij waterput together two builds of mining computers that should be capable of similar hashrates:

Te thesis two builds, the core toneelpodium stays the same, with the AMD Sempron 145 Single Core processor. While this processor would be essentially futile for a loterijlot of other tasks, Coin mining on a GPU is not a CPU intensive task, so wij can get away with one of the cheapest CPUs on the market.

Wij chose the Gigabyte 990FXA-UD3, spil it wasgoed the cheapest motherboard wij could find for this toneel with 6 PCI-Express ports.

Spil you have most likely noticed not all of the PCI-E ports on this motherboard permit for a x16 card to be plugged ter, and even the ones that are capable don`t have decent spacing for Two slot cards. To remedy this wij have included the adequate adapters.

Due to the fact that wij are using PCIE risers, there is no case included. You would most likely be best served by building an open-air test leger for the system out of milk crates, shelving systems, wood, or some other building material. Just reminisce, it doesn`t have to look pretty to be effective!

There is also no storage option included. For something like this you could either use any spare hard drive you have laying around, or even install a Linux distribution to a thumb drive. Due to this, wij found storage to be a negligible option.

Very first, wij have a more traditional build, using Four x R9 270Xs, which wij found available on Amazon right now for just above $300 each. With Four of thesis cards running at about 450KH/s each, wij should have a 1.8MH/s machine. With a power draw of 150W from each card, wij get a total of 600W just for the GPUs alone. Throwing ter another 75W for the 45W TDP processor and any extra overhead, wij come to approximately 675W power draw for our entire mining equipment.

At a total cost of around $1520, this machine would have a payoff period of about 113 days at the current Dogecoin rates, at 1.8MH/s

Our 2nd build is based on the GTX 750 Ti. This time wij instead opted for 6 x 750 Ti cards for a total of $900, which is still significantly lower than the $1200 for Four 270Xs. With 6 x 750 Ti cards, the estimated GPU power draw would only be 360W, just above half of the power draw of the 270X machine. Adding ter the same 75W for extra system components the total estimated power draw works out to 435W, which permits us to purchase a cheaper power supply.

At a total cost of around $1300, this machine would have a payoff period of about 97 days at the current Dogecoin rates, at 1.8MH/s

Spil you can see, by cramming more of the lower end but amazing GTX 750 Ti`s into a single machine you can create a similar performing machine for less money than the AMD alternative, which is contrary to all the advice given about coin mining up to this initial release of Maxwell. Ter addition, voorstelling of the Maxwell-based machine should only improve spil the Maxwell kernel for cudaMiner is developed further, whereas OpenCL spectacle for AMD mining has likely bot spil optimized spil wij will everzwijn see it.

An extra factor you have to keep ter mind is the fluctuating cryptocurrency market. Just because the payoff estimates today say you could be making a profit te 80 days, doesn`t mean that will remain the same te the future. While the estimate could get better, it also could get a lotsbestemming worse, leaving you with a loterijlot of hardware to sell off ter the future.

While no one is sure where the mining market will be spil far spil profitability is worried when the high end Maxwell GPUs klapper the market, NVIDIA could have a similar stock issues and an inability to produce GPUs to gamers spil wij see AMD having today.
