Douglas Eadline has put some of the latest multicore processors through their paces in a new feature article on the ClusterMonkey site. Rather than using the fastest (and most expensive) processors available, Eadline went with the following 65-Watt desktop chips:
- Intel Core2 Quad-core Q6600 running at 2.4GHz (Kentsfield)
- AMD Phenom II X4 quad-core 910e running at 2.6GHz (Deneb)
- Intel Core i5 Quad-core i5-2400S running at 2.5 GHz (Sandybridge)
Generational advances (like memory architecture) travel through the whole product line from desktop to server. The high end server processor may work 20% faster than the lower end desktop processors, but the cost is usually much more (almost always more than 20%). Thus, by using lower cost desktop parts, a large percentage of the “high end” performance can be had at a low end price. The Limulus Project is designed to take advantage of this marketing trend. And, to be clear, the Limulus Project is not a replacement for a large server based cluster. The testing is designed to measure how well a single multi-core processor performs with multiple programs running on it. Using single core performance as a measure of multi-core performance is difficult if not impossible. Thus, looking at parallel performance and scalability is the real measure of a modern multi-core processor.

Great the multi core processor indeed helps in speedning the process, and makes one very comfortable.
Hi There
Thanks for keeping good original content on the web. Not everyone has the ability to find such good technical information on good core processers. This data will help people decide what PC is best for them since they understand more about the performance of the core processor in the computer that the like.
How do you prove to your readers what the reliability is of the data sources you quote for the throughput mbit / s ?
Gracias por mantener un buen contenido original en la web. No todo el mundo tiene la capacidad de encontrar una buena información técnica sobre los procesadores centrales buena. Esta información ayudará a las personas decidir qué PC es mejor para ellos ya que entienden más sobre el rendimiento del procesador de núcleo en el equipo que por el estilo.
¿Cómo demostrar a sus lectores lo que la fiabilidad es de las fuentes de datos que usted cita para el rendimiento Mbit / s?
