One of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. Here are pictures of a few of my rigs: 10 steps to implement and deploy your Bitcoin Mining Rigs. Below are the 10 steps to getting your bitcoin mining rigsBelow are statistics about the Bitcoin Mining performance of ASIC hardware and only includes specialized equipment that has been shipped.
GPUs, CPUs and other hardware not specifically designed for Bitcoin mining can be found in the Non-specialized_hardware_comparison. Notes: Mhash/s = millions hashes per second (double sha256 raw speed performance; may not be very energy efficient with some models) Mhash/J = millions hashes per joule (energy efficiency; 1 joule of energy is 1 watt during 1 second: 1 J = 1 W*s) W = watt (maximum power consumption, i.e. energy per unit of time: 1 W = 1 J/s) Be sure to research any of these vendors and machines intensely before spending any money.

More precisely, a major disadvantage to the actual Bitcoin mining process is the cost vs. revenue battle, where you may be spending more money on generating bitcoins than you are earning with the bitcoins you have mined. This can vary based on the hardware you use for mining as well as the current value of a bitcoin. However, even if you have read about the disadvantages to the process and have read our Bitcoin guide, you may have still decided to go for it and build yourself one or more Bitcoin mining rigs. The CPU does not matter for any bitcoin mining machines as the GPU(s) will do all of the work.
As this page explains, GPUs can do a lot more number-crunching than CPUs can, which leads to faster mining. We also wrote another article which highlights differences between CPUs and GPUs without a focus on bitcoin mining. Therefore, even the cheapest AMD CPU will do just fine, as you will want to save theThe era of Bitcoin mining on the GPU is dead.
A year ago, a single Radeon graphics card could crank out a reasonable fraction of a Bitcoin in a single day. Today, that same GPU earns a thousandth of a Bitcoin in 24 hours, generating little value while consuming a substantial amount of power. The shift to ASICs for Bitcoin mining mirrors the shift from CPUs to GPUs, but the market isn’t content to just turn those mining rigs off — not when there’s an alternative currency available for which ASIC miners do not exist. That alternative is Litecoin — and there’s reason to think that buyers have emptied the shelves of AMD’s Radeon hardware to build mining platforms. First off, there’s the fact that you can’t find a high-end Radeon in stock at the moment. Newegg and Amazon are both out of stock, while over at Amazon, the lowly AMD Sempron 145 — a single-core, 2.8GHz chip with a $29.75 price — is the 5th most popular CPU . Further proof of this trend is the Litecoin network hash rate, is shownSome Bitcoin users might wonder why there is a huge disparity between the mining output of a CPU versus a GPU. First, just to clarify, the CPU, or central processing unit, is the part of the computer that performs the will of the software loaded on the computer. It s the main executive for the entire machine. It is the master that tells all the parts of the computer what to do - in accordance with the program code of the software, and, hopefully, the will of the user. Most computers have multi-core CPUs nowadays (which is almost the same thing as having multiple CPU s in a single physical package)., and some computers even have multiple CPUs. The CPU is usually a removable component that plugs into the computer s main circuit board, or motherboard and sits underneath a large, metallic heat sink which usually has a fan, a few are cooled by water. The GPU, or graphics processing unit, is a part of the video rendering system of a computer. The typical function of a GPU is to assist withI got a Radeon HD 5970 on Craigslist for 400 USD, which is about half what it sells for new. If everything goes well I should have paid for it and all the electricity in a couple of months. If everything doesn t go well, I guess I ll have to console myself with my super-cheap video card. I wouldn t buy new hardware solely for mining unless I could get an equally good deal again. Look on Craigslist or sites like that.
A used 5770 sounds reasonable and will be a nice upgrade for your PC too. I shall check Craigslist, but being that I live on Kauai (Small island on the west of the Hawaiian chain) I don t know how much tech will be there. ;P I do a lot of GPU calculations, and have been getting into parallel programming recently.
So this wouldn t only be for mining purposes. I m more interested in porting CAL++ to poclbm. I too was looking for something under 100, and I too decided on the 5770. However, after looking around Ebay for a while, I figured I may be able to get lucky going a.
