New GPU Testing Methodology Puts Multi-GPU Solutions In Question

ADDED BONUS: many have already have all the equipment they need to get started. Like you said, it's a fun hobby.

New GPU Testing Methodology Puts Multi-GPU Solutions In Question

amanicdroid Re:You use GPUs for video games? (112 comments)

Considering the cards overheat at above 120 C and overclocking doesn't really do anything for hashing, miners in hot climate could put the boxes in a protected area outside and suffer few ill effects.

Mine is a joke? People call it waste heat, I use and enjoy the waste heat so I made a joke about it.

I doubt a natural gas furnace even has a PCIx16 slot much less match even a budget Nvidia's hashing specs.

^See what I did there? Another joke.

New GPU Testing Methodology Puts Multi-GPU Solutions In Question

Bitcoins stayed around $13 to 1 for months and you're correct, there wasn't a breakeven point for GPU mining. With Bitcoins trading at $30 the breakeven point is available again. For how long, I don't know, and I wouldn't bet a business on it.

New GPU Testing Methodology Puts Multi-GPU Solutions In Question

This is the explanation I've been given for the disparity between Nvidia and AMD:
https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU#Why_are_AMD_GPUs_faster_than_Nvidia_GPUs.3F

Specifically:

Secondly, another difference favoring Bitcoin mining on AMD GPUs instead of Nvidia's is that the mining algorithm is based on SHA-256, which makes heavy use of the 32-bit integer right rotate operation. This operation can be implemented as a single hardware instruction on AMD GPUs (BIT_ALIGN_INT), but requires three separate hardware instructions to be emulated on Nvidia GPUs (2 shifts + 1 add). This alone gives AMD another 1.7x performance advantage (~1900 instructions instead of ~3250 to execute the SHA-256 compression function).

For GPU programming I've enjoyed Nvidia's CUDA package greatly over wrangling OpenCL that Radeon relies on.

Waste heat? You mean my ATI Radeon 200W Space Heater® that takes away the night chills?

Haha, I'm at less than 1:1 electricity to bitcoin ratio after ~5 months.
Kill-A-Watt says I've used approx $68.23 of electricity at 11.5 cents per kWh. Bitcoins currently trade at 1 to $30 and I've got 2.2 bitcoins. The Radeon 6770 was (and still is) ~$110.

Additional factors to consider:
-The bitcoin machine is also my daily workstation so if it were running headless and otherwise unused it would have probably done better in the electricity used category.
-It makes a damn fine space heater and I've enjoyed it immensely this winter.
-My focus in this project was to learn hands-on about scientific computing applications and it's been great for that.

In conclusion: as a business it would have been a flop, partially because I haven't optimized the setup for that application. As a learning opportunity and 200 watt heater it's been phenomenal.

My AMD is cranking out Bitcoin hashes 15 times faster than an equivalently priced Nvidia so I'm okay with the results of this article.

Certain 'Personality Genes' Correlate With Longevity, Says Study

amanicdroid I am surprised. (72 comments)

So the angry hobo that stands in traffic screaming at cars will die sooner? Now if we could somehow correlate his behaviour with his genes while taking social factors into account as well.

UK Plan Would Use CCTV To Stop Uninsured Drivers From Refueling

amanicdroid Re:Unintended consequences (691 comments)

Give a man a siphon hose and he can drive for a day. Teach him how to puncture a gas tank to collect fuel and he can drive for life.

Or something.

Indonesian Man Faces Five Years For Atheist Facebook Post

amanicdroid Re:The real problem here (907 comments)

First of all: many people have had the balls to stand up and say that.

Secondly, many have had the balls to say it while not hiding their face as an anonymous coward merely tossing gasoline on the Slashdot bonfire.

Sweden Experiments With Public Twitter Takeover

amanicdroid Re:I have enjoyed following the new Sweden account (64 comments)

The Stockholm, Oslo, Copenhagen triangle looks interesting. I imagine that touring it would keep me busy for a week. The Aland islands look promising as well.

I'll keep your advice about visiting in spring or summer as the Arctic circle passes through that area. :)

Sweden Experiments With Public Twitter Takeover

amanicdroid I have enjoyed following the new Sweden account. (64 comments)

I have enjoyed following the new Sweden account and would consider visiting after enjoying the country shared from the viewpoint of common citizens. I have never looked at a brochure from the Bahamas and found it convincing or enticing.

In my case, it's entertaining and an effective ad campaign. The Swedish tourist bureau should probably win a medal or a cookie or something for an effective campaign.
