Most computers have multi-core CPUs nowadays which is almost the same thing as having multiple CPU's in a single physical package. Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts. I use it also. This page was last modified on 8 January , at One way to visualize it is a CPU works like a small group of very smart people who can quickly do any task given to them. Thanks for the idea for this. The structures that make CPUs good at what they do take up lots of space.

Why a GPU mines faster than a CPU - Bitcoin Wiki

A GPU is very different. Yes, a GPU can do math, and can also do "this" and "that" based on specific conditions. However, GPU's have been designed so they are very good at doing video processing, and less executive work. Video processing is a lot of repetitive work, since it is constantly being told to do the same thing to large groups of pixels on the screen.

In order to make this run efficiency, video processors are far heavier on the ability to do repetitive work, than the ability to rapidly switch tasks. As a result, they can do large amounts of bulky mathematical labor in a greater quantity than CPU's. One way to visualize it is a CPU works like a small group of very smart people who can quickly do any task given to them. A GPU is a large group of relatively dumb people who aren't individually very fast or smart, but who can be trained to do repetitive tasks, and collectively can be more productive just due to the sheer number of people.

It's not that a CPU is fat, spoiled, or lazy. On silicon chips, size is expensive. The structures that make CPUs good at what they do take up lots of space. When those structures are omitted, that leaves plenty of room for many "dumb" ALU's, which individually are very small.

They can either all work on nearly identical variations of one single task, in perfect sync with one another, or nothing at all. Trying different hashes repeatedly - the process behind Bitcoin mining - is a very repetitive task suitable for a GPU, with each attempt varying only by the changing of one number called a "nonce" in the data being hashed.

The ATI Radeon is a popular video card for Bitcoin mining and, to date, offers the best known performance of any video card for this purpose. This particular card has 3, "Stream Processors", which can be thought of as 3, very dumb execution units that can be trained to all do the same repetitive task, just so long as they don't have to make any decisions that interrupts their flow.

Those execution units are contained in blocks. The uses a VLIW-5 architecture, which means the 3, Stream Processors are actually "Cores," Each able to process 5 instruction per clock cycle. Nvidia would call these cores "Cuda Cores", but as mentioned in this article, they are not VLIW, meaning they cannot do as much work per cycle. This is why comparing graphics cards by core count alone is not an accurate method of determining performance, and this is also why nVidia lags so far behind ATI in SHA hashing.

Trying a single SHA hash in the context of Bitcoin mining requires around 1, simple mathematical steps that must be performed entirely by ALU's.

Bitcoin mining requires no decision making - it is repetitive mathematical work for a computer. The only decision making that must be made in Bitcoin mining is, "do I have a valid block" or "do I not". That's an excellent workload to run on a GPU. Because of this VLIW vs. Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts.
