TreeMark™ Tree Rating – A fresh perspective to green computing

31 Aug

Recently, we have been seeing lots of energy-efficient products entering our lives, the change has been triggered by factors like rising oil prices, increase in environmental pollution and soaring electricity costs. There has been a significant shift towards energy efficient computers, especially in the data centers.

Centaur Technology have come up with a very interesting way of evaluating the energy efficiency of micoprocessor products. It is called the TreeMark™ Tree Rating. Centaur defines it as “The number of trees that need to be planted to counter the amount of carbon dioxide created as a by-product of the electricity generated to power the processor over its operational lifetime”. The good thing is, Centaur’s processors rate very well on this benchmark when compared with their Intel or AMD counterparts.

I still keep on wondering what would be the TreeMark rating for the components other than the processor in a computer. If a processor’s TreeMark rating is 7 trees, the rest of the electronics in the computer could raise the bar by 14-20 more trees. Not to mention the amount of thermal cooling required in the datacenters.

The situation demands more involvement in the process of creating energy efficient compute appliances on part of the industry leaders. I would like to mention the good work done by IBM for the Power6 Processor.

The figure below shows how the TreeMark Tree rating can be calculated for an electrical load.

    Thank you for discussing green computing. I'm linking to this posting from my site at http://cherrypal.blogspot.com

    I could not find the company you reference, "Centaur semiconductors", but I did find VIA Technologies at http://www.via.com.tw/en/initiatives/greencomputi… where they discuss this Tree Marking. Perhaps they make the semiconductors…

    I'm interested in green computing, cloud computing and as such am an anticipated fan of the CherryPal C100 desktop, which is being touted as a cloud computer. The CherryPal™ C100 desktop is about the size of a paperback book with the performance you would expect from a full-size desktop computer. It has Freescale’s triple-core mobileGT processor for multimedia performance and feature-rich user interfaces, while only consuming as much power as a clock radio. CherryPal uses 80 percent fewer components than a traditional PC, and because it has no moving parts, it operates without making a sound and will last 10 years or more. I am excited about how the CherryPal can bridge barriers to people who have not had access to computers or the internet because of money, fear, education or other challenges. I will be commenting on my experience of using it on my blog as soon as I get my own CherryPal C100! You can use CODE CPP206 to get your own CherryPal for $10 less than purchase price.

      Hi Solmn,

      Could you please tell what roadmap is there for Cherrypal considering players like RaspberryPI are being the focus of community attention?

      Thanks

    Solmn, thanks for the appreciation. I mistakenly mentioned Centaur Sermiconductors which is not correct. The correct name of the company is Centaur Technology. I have made a correction to the post on my blog. The company is a wholly owned subsidiary of VIA Technologies. They were known as IDT Centaur back in 1996 when they created the famous low power WinChip x86 processor. The details about the WinChip can be found here http://en.wikipedia.org/wiki/WinChip .
