Advantages: Very cheap, extremely low power consuption, can be used with fanless cooler
Disadvantages: Poor performance compared with today multi core processors

Well what can I say, single core processor, I used to have something like this not so long ago, a good processor then but now a new era of processors had arrived, the dual core and quad core processors. Nevertheless the processor has it's own and unique advantages and disadvantages: The good stuff: Still not many multi thread aplications that the processor deals pretty well Magnificent power consumption, only 30-35 watt on full load, and 5-6 watt ...
...fan less cooler for a silent and energy efficient computer So cheap The not so good stuff: Modest performance in single threaded aplications Poor performance in multi threaded aplications Say goodbye to HD movies (although some video cards can decode HD movies, but why risk: ) and future applications Modest over clocking on low cost motherboards, only 300-500 Mhz Conclusion: recommended for silent and energy efficient office computers ...

Advantages: Price, low power consumption
Disadvantages: Small L2 cache

It's low (35 watt) power consumption makes it an ideal candidate for a media player computer, an office computer or for browsing the internet. I've tested one of this processors, and it performed very well in every day tasks, but it also had it's not-so-well performances. The good: Very cheap Low power consumption It's low power consumption also makes is a cool processor, so cool that you can use a fanless cooler without having to worry about ... Read review

Advantages: ideal for intense computing environments
Disadvantages: none

...unbelieveable performance and The Dual-Core Intel Xeon processor 5100 series is ideal for intense computing environments, 32-bit and 64-bit business-critical applications and high-end workstation and Analysis in my mind Dual-Core Intel Xeon processor 5100 series-based platforms are expected to deliver up to 2.25 times the performance and 2.35 times the performance/watt of previous-generation dual-core Intel Xeon processors and realiable performance ...

Advantages: Intelligent Power Capability
Disadvantages: none

These new processors deliver amazing performance and power efficiency.With four execution cores, the Intel® Core™2 Quad processor blows through processor-intensive tasks in demanding multitasking environments and makes the most of highly threaded applications. Graphics Video works Just SUPER.Keep it cool, and you should be able to do some over clocking. I turned my ASUS auto overclocking off since I really dont need to over clock (& void the ...

Advantages: Cheap, Powerfull
Disadvantages: Small L2 cache

This is brilliant processor for its small price. In fact i like it so much, im writing this review using it right now. It is really easily over clocked using the right mother board. Personally, i have overclocked to 2.5Ghz using a cheap Gigabyte motherboard and an arctic cooling freezer 7 pro heat-sink fan unit. I have found that it is brilliant for multi-tasking. Even the programs that heavily use CPU power are done with ease on this powerful little ...
...obviously depending on case cooling and heat-sink fan, its not too bad. In my computer i have 3 additional 80cm fans for cooling as well as the heat-sink fan and im peaking at 45 degrees Celsius. The only disadvantage i can see with the CPU would be the L2 cache size. At only 1GB its not as fast as the Core 2 Duo CPU's but at this price its worth it. ... Read review
