Currently, the Nehalem Core i7 gives the best performance, but will cause a lot of heat on your laptop.
You wouldn't want the best probably.The very best gaming cpu's are ungodly expensive.Right now the Phenom II X3 720BE is one of the best price/performance processors.Several other of AMD's Phenom cpus give you superb performance for the money.
CPUs are designed especially for Laptops. They will shut off portions of themselves when not in use.
That depends on your usage. If you plan to use a lot it while standing or walking, tablets are great for that. If however, your most common usage will be at a desk or in a chair a laptop will be a better option. Your average tablet is the same size as a smaller laptop, they are generally geared towards battery life, and as such are usually equipped with lower-speed lower-power consumption cpus. So if you want a big screen & good gaming performance, laptop. There are many systems which can do both. It is accomplished by using a screen which can swivel 180 degrees for tablet mode. This may be the best option for you, although it comes at a premium.
Depends on the person you ask and what your price to performance ratio is. Amd is the cheaper of the two compared to intel. Amd has good cpus for less than comparable Intel cpus. If money is not to much of a problem then Intel will be your best bet.
A laptop processor is a CPU optimized for Laptops. One of the main characteristics differentiating laptop processors from other CPUs is low power consumption.
Intel = buissness and work AMD= gaming and raw power
You want to find a good price for a good core CPU model laptop. The best way to do this is to keep an eye on the CPU industry, especially Intel and AMD. Know when they are upgrading their CPUs with new developments. Once Intel takes the lead, not only will AMD try to soon follow, but the recent CPU model Intel computers will drop down in price, and this includes laptops. The best time to check out laptop computer sales is when the competing CPU industry has decided to produce new CPUs.
The CPUs in desktop computers are designed to provide maximum performance. This is usually not a concern for mobile computers; power efficiency and low heat are more important. So the processors in laptops and handhelds are designed slightly differently from those in desktops, to fit the needs of mobile suers better.
AMDs 'dual core' CPUs, those that contain 2 CPU cores, as opposed to the 1 CPU core found in earlier AMD (and intel, VIA, cyrix etc) CPUs. Dual core CPUs have much better multitasking performance than traditional single core CPUs.
On Intel CPUs which support IA-32 , the best is Protected Mode. But as for Intel CPUs supporting IA-32e ,the best is 64-bit Mode.
It's impossible to answer this question. There are hundreds of high speed processors. Be more accurate. There are CPUs that cost more than $1000 and there are also CPUs that cost $300. If you need it for a server or heavy rendering - $1000, if gaming $300.
One of the better places to view CPU benchmarks is on Passmark. It is good for comparing CPUs, both by performance and by price. They also have trial software you can download to see how your computer compares. If you want to use it past the trial, you have to purchase it.
