Top Most Eco-friendly and Economical CPU's Chart

It is now time that people start factoring in what is Eco-friendly, mainly because Eco-friendly is quickly becoming the new economical. This is especially true for CPU's as they can be a major power hog with computers running almost 24/7 nowadays. Let the battle for the most Eco-friendly (and economical) CPU begin.

The most Eco-friendly and economical desktop CPU will be based on the following properties:

• Energy consumption of CPU
• Cost of CPU
• Clock rate of CPU (multiplied by number of cores)

The following CPU's will be used in this calculation:

• Intel Core i7 930 Processor
• Intel Core i7 920 Processor
• Intel Core 2 Quad Q9550 Processor
• AMD Phenom II 1055T Six Core Processor
• Intel Core i7 980X Extreme Edition Processor
• AMD Phenom II X4 955 Black Edition Processor

Now, the formula that will be used for this calculation is as follows (lower is better):

(Energy Consumption * Cost) / Combined Clock Rate of Cores

Here are the results, with the most efficient and economical desktop CPU's on top:

1. AMD Phenom II 1055T Six Core Processor [Result=1488]
2. AMD Phenom II X4 955 Black Edition Processor [Result=1563]
3. Intel Core 2 Quad Q9550 Processor [Result=2266]
4. Intel Core i7 920 Processor [Result=3299]
5. Intel Core i7 930 Processor [Result=3482]
6. Intel Core i7 980X Extreme Edition Processor [Result=6507]
