(confer however with the ati curse mentioned earlier regarding the 750ti)

and as my friend pointed out, with a high tier maxwell in the wings, it may be that the cost savings would not make up for capital switch costs til we have an idea of the maxwell high tier data. (But if you were already going for the 250 to 270 ATIs, then it may make sense to swap straight to the 750 ti now)

It will be pretty impressive if the high end maxwell can even surpass this performance to power ratio for 750 ti.

For that I guess we will have to wait a while to see…

Buried on the 17th page of Tom’s Hardware’s GeForce GTX 750 Ti graphics card review is a simple benchmark result that will dramatically disrupt the landscape of cryptocurrency mining. In fact, it’s the kind of data that should send AMD back to the drawing board — at least if they want to maintain their choke-hold on the mining hardware market.

Historically AMD has been the undisputed crowd favorite of miners looking to stock up on new forms of digital currency like Dogecoin and Litecoin. AMD’s Radeon graphics cards possess a secret sauce that allows significantly more powerful compute capabilities, at least the kind required for Scrypt-based mining.

What you’re looking at in the image above is a hashrate of about 242kh/s using Nvidia’s reference 750 Ti 1GB graphics card ($139). This is significant for several reasons. First, the 750 Ti is a 60Watt card and doesn’t even require a PCI-E power connector. You could plug this card into a cheap box from HP or Dell with a 300W power supply and have power to spare. Second, the temperature never seems to breach 65 degrees Celsius, and it runs considerably quieter and cooler than the AMD 260x ($119), which achieves a peak hashrate of 206kh/s and consumes nearly 130Watts of power.

For that same price of $149, here’s what I pulled off with PNY’s 750 Ti 2GB with a moderate (and stable) overclock:

PNY GTX 750 Ti overclocked and using Cudaminer to mine Dogecoin.

A single PNY 750 Ti 2GB graphics card, overclocked and using Cudaminer to mine Dogecoin.

That’s right, 284kh/s, and an even better temperature ceiling of about 56 degrees Celsius. This is consuming less than half the power of AMD’s Radeon 265.
