Just when we all thought that AMD is king of the hill, along comes a Nvidia contender powered by their heavily plugged Maxwell chip – and knocks the R7 for 1st place. A recent comparison test done by Tom’s Hardware reveals the facts:
The GeForce GTX 750 Ti achieves 245 kh/s which is almost 40 kh/s faster than its nearest AMD rival, the R7 260 X which outputs 206 kh/s. The GTX 750 Ti achieves the hash rate by consuming only 60W of power compared to the R7 260 X’s 130W. Although the Nvidia card is $20 more expensive by RRP, the bang-for-buck factor is significant and makes the GTX 750 Ti the surprise winner.
The bigger surprise is that the closest competitor above: the AMD R7 265 also falls short of the GTX 750 Ti in measures of value for money and power efficiency. Although the R7 265 output is 252 kh/s, a 7 kh/s advantage, it does so by burning through 150W of power – more than double the consumption of the GTX 750 Ti! So from a TCO perspective you would be paying $11 more for the R7 265’s extra 7 kh/s only to pay double the cost in electricity throughout its useful life! Hmm. Which one to choose, eh?
A recent article in Forbes featured the GTX 750 Ti in an overclocking experiment (shown in the image below). It achieved 280 kh/s without distress to CUDAminer, and did so without rising above 60 degrees Celsius.
So, from the perspective of mining output per Watt, the GTX 750 Ti is best of breed. This calls into question the current preoccupation with AMD Radeon and the favor it enjoys. Is it justified? Apparently not, and Nvidia is nowhere near out of the mining GPU race yet.
As the Mining Performance per Watt chart below illustrates, the AMD flagship R9 290 is fairly power hungry. This is, of course, justified by its incredible output of 500 kh/s. If your rig allows it and your business plan demands it, you may find the unparalleled R9 290 to be the card for you. For the average miner, who is looking for a fast and cost effective card, the Nvidia GTX 750 Ti is a recommended buy.
Some miners mistakenly believe that GPUs are being made redundant in the mining sector by the rise of Scrypt ASICs. Think again!
A new generation of altcoins, notably Execoin, are specifically designed to be ASIC resistant and argue that GPU mining is yet to experience it’s hey-day. Read what the Execoin developers have to say about the coming ASIC Invasion.
With AMD making a big deal of its forthcoming High Bandwidth Memory (HBM) Pirate Islands series, Nvidia is sure to follow. We can expect more miners to pile into the buying side for this new generation of GPUs, which look to challenge the notion that ASICs are the path to mining nirvana.
