Best Processor for Laptop Computers? Intel Core i Laptop Processors

If you listen to Intel, the best processor for laptop computers is one of there new core i processors. They claim they are the best laptop processor. They're probably right.

• Intel Core 2 Extreme
• Intel Core 2 Quad
• Intel Core 2 Duo
• Intel Core Duo
• Intel Core 2 Solo
• Intel Core Solo
• Intel Pentium Dual Core
• Intel Celeron
• Intel Atom

The letters you have seen before the numbers and their meanings are:

• Q There are four cores combined in the processor.
• X Extreme. A top end high performance processor.
• T Power consumption -- Total design power (TDP) 30-39 watts
• P TDP 20-29 watts
• L TDP 12-19 watts
• U TDP 11.9 watts or less
• S small form factor
• N Network processor

The family names you'll see in 2010 are

• Intel Core i7
• Intel Core i5
• Intel Core i3
• Intel Celeron
• Intel Atom

Intel added a new letter. Mobile Core i processors now will have an M in the name.

This years Atom processors are the newer 32 mn. processors and you will find them in mini notebook computers. Intel has also changed what some of the letters mean when you look at the labeling of core i mobile processors. L and U no longer mean what they did. The "L" processors have a TDP of 25 Watts. The "U" processors have a TDP of 18 watts. It seems they are a level higher than they were. The "P" designation seems to have disappeared. The "L" seems to use the power the "P" did and the new "U" matches the old "L".

The core i7 mobile chips are not all the same. Three, the i7-720QM, the 820QM and the 920XM are older style chips. They were announced last September and have actually appeared in computers that have been for sale. These chips and the Celeron chips still use power at the old "T" level. There are several ways they differ from the 11 core i chips announce at the Consumer Electonics Show this year. The older chips

• are 45 nm. thick
• use more power
• do not have additional components integrated into the cpu

The new processors announced were

• Core i7-640LM
• Core i7-640UM
• Core i7-620M
• Core i7-620LM
• Core i7-620UM
• Core i5-540M
• Core i5-520M
• Core i5-520UM
• Core i5-430M
• Core i3-350M
• Core i3-330M

Whether these older chips or the newer models are the best processor for laptop computers is still to be seen.The new chips are the first 32 nm. mobile chips. The smallest chips last year were 45 nm. No Intel chips had the graphics processor and the memory controller integrated into the same package as the cpu. Intel has taken one of the two mother board chip sets and added it to the cpu.

This has several benefits. The TDP listed for the mobile processor includes several other items which consume power. The overall power consumption for the total components involved would put cpu the in or below the L or U designation if only the power for the laptop cpu was measured. The on processor memory controller allows for faster and more efficient use of the system memory. An integrated memory controller allowed laptops AMD processors to remain somewhat competitive with Intel even though the processors are slower. As we said when discussing the 60nm. and 45 nm. processors as compared to the 90 nm. processors, they are naturally faster. With everything smaller, instructions get where they were sent quicker, and less heat is generated with the smaller distances for electric current to travel. In many ways they are the best processor for laptop computers.
