Not content to ruin the hopes of gamers wanting to upgrade to a Hawaii based AMD GPU now your smart devices are being press ganged into mining crypto-currency. Everything from TVs and fridges through printers, routers and security cameras can be infected with the linux.darlloz worm and will then begin mining for the author of the worm. The worm will even block other infections and has even been monitored patching certain holes in routers to prevent anything else from infecting the device and slowing down the mining computations. The Inquirer does have some humourous news about this worm, there are 31,716 separate IP addresses infected but this has manged to raise a mere $196.00 so for the author.
"A WORM that leverages the Internet of Things to mine cryptocurrencies has been found to have infected around 31,000 devices."

As we have talked about on several different occasions, Altcoin mining (anything that is NOT Bitcoin specifically) is a force on the current GPU market whether we like it or not. Traditionally, Miners have only bought AMD-based GPUs, due to the performance advantage when compared to their NVIDIA competition. However, with continued development of the cudaMiner application over the past few months, NVIDIA cards have been gaining performance in Scrypt mining.
The biggest performance change we've seen yet has come with a new version of cudaMiner released yesterday. This new version (2014-02-18) brings initial support for the Maxwell architecture, which was just released yesterday in the GTX 750 and 750 Ti. With support for Maxwell, mining starts to become a more compelling option with this new NVIDIA GPU.
With the new version of cudaMiner on the reference version of the GTX 750 Ti, we were able to achieve a hashrate of 263 KH/s, impressive when you compare it to the performance of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.
As you may know from our full GTX 750 Ti Review, the GM107 overclocks very well. We were able to push our sample to the highest offset configurable of +135 MHz, with an additional 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 additional 40 KH/s or so of performance, bringing us to just under 300KH/s with the 750 Ti.
As we compare the performance of the 750 Ti to AMD GPUs and previous generation NVIDIA GPUs, we start to see how impressive the performance of this card stacks up considering the $150 MSRP. For less than half the price of the GTX 770, and roughly the same price as a R7 260X, you can achieve the same performance.
When we look at power consumption based on the TDP of each card, this comparison only becomes more impressive. At 60W, there is no card that comes close to the performance 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 roughly the same hash rate.
Taking a look at the performance per dollar ratings of these graphics cards, we see the two top performers are the AMD R7 260X and our overclocked GTX 750 Ti.
However, when looking at the performance per watt differences of the field, the GTX 750 Ti looks more impressive. 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 we will likely see released later in 2014.

Tagged: supply shortage, shortage, R9 290X, podcast, litecoin, dogecoin, bitcoin
UPDATE (Feb 14th, 11pm ET): As a commenter has pointed out below, suddenly, as if by magic, Newegg has lowered prices on the currently in stock R9 290X cards by $200. That means you can currently find them for $699 - only $150 over the expected MSRP. Does that change anything about what we said above or in the video? Not really. It only lowers the severity.
I am curious to know if this was done by Newegg voluntarily due to pressure from news stories such as these, lack of sales at $899 or with some nudging from AMD...
If you have been keeping up with our podcasts and reviews, you will know that AMD cards are great compute devices for their MSRP. This is something that cryptocurrency applies a value to. Run a sufficient amount of encryption tasks and you are rewarded with newly created tokens (or some fee from validated transactions). Some people seem to think that GPUs are more valuable for that purpose than their MSRP, so retailers raise prices and people still buy them.
Currently, the cheapest R9 290X is being sold for $900. This is a 64% increase over AMD's intended $549 MSRP. They are not even the ones receiving this money!
This shortage also affects other products such as Corsair's 1200W power supply. Thankfully, only certain components are necessary for mining (mostly GPUs and a lot of power) so at least we are not seeing the shortage spread to RAM, CPUs, APUs, and so forth. We noted a mining kit on Newegg which was powered by a Sempron processor. This line of cheap and low-performance CPUs has not been updated since 2009.
We have kept up with GPU shortages, historically. We did semi-regular availability checks during the GeForce GTX 680 and 690 launch windows. The former was out of stock for over two months after its launch. Those also sometimes strayed from their MSRP, slightly.
Be sure to check out the clip (above) for a nice, 15-minute discussion.

I know we have posted about this a few times on PC Perspective and have discussed it on the PC Perspective Podcast as well, but if you are curious as to why the prices of AMD's latest generation of R9 graphics cards have skyrocketed, look no further than this enterprising consumer and his/her Dogecoin mining rig.
What you are looking at are six MSI Gaming series R9 270 cards running through the aid of PCI Express to USB 3.0 riser cards.
