One of the more interesting demonstrations from CES thus far has come from Intel in the form of power consumption comparisons between three of the current tablet SoC solutions. Intel pits the Clovertrail SoC against NVIDIA's Tegra 3 and Qualcomm's Krait in a battle of power efficiency during video playback. What you'll see is that Intel's test shows the Clovertrail processor able to not only run near but surpass the power efficiency of the ARM-based processors shown.
This is an incredibly powerful collection of tools that Intel has presented and we are hoping to be able to dive into a similar level of detail in the future. By utilizing direct monitoring of power VRMs on the processor we could even see the power consumption of the CPU cores in comparison to the GPU cores and even against the L2 cache in some instances.
Intel is on a mission to prove that they are not only competitive today in the tablet SoC market but that they are a leader in the market. More to follow!!

How much will these Bitcoin mining configurations cost you in power?
Earlier this week we looked at Bitcoin mining performance across a large range of GPUs but we had many requests for estimates on the cost of the power to drive them. At the time we were much more interested in the performance of these configurations but now that we have that information and we started to look at the potential profitability of doing something like this, look at the actual real-world cost of running a mining machine 24 hours a day, 7 days a week became much more important.
This led us to today's update where we will talk about the average cost of power, and thus the average cost of running our 16 different configurations, in 50 different locations across the United States. We got our data from the U.S. Energy Information Administration website where they provide average retail prices on electricity divided up by state and by region. For use today, we downloaded the latest XLS file (which has slightly more updated information than the website as of this writing) and started going to work with some simple math.
Here is how your state matches up:
The first graph shows the rates in alphabetical order by state, the second graph in order from the most expensive to the least. First thing we noticed: if you live in Hawaii, I hope you REALLY love the weather. And maybe it's time to look into that whole solar panel thing, huh? Because Hawaii was SO FAR out beyond our other data points, we are going to be leaving it out of our calculations and instead are going to ask residents and those curious to just basically double one of our groupings.
Keep reading to get the full rundown on how power costs will affect your mining operations, and why it may not make sense to mine AT ALL with NVIDIA graphics cards!
