What makes a good Laptop Processor?
When buying a laptop one of the most important specifications is the notebook processor. Desktop processors are different from laptop processors because for them not only the performance counts, but also how much energy they consume.
What is a processor? A processor is like the brain of the Laptop. It does all the calculations necessary. From starting the notebook, to surfing the web with a Browser, the Processor does all the thinking necessary. The better the processor is, the faster you can start programs.
A few years ago a fast processor was necessary for many programs to run properly. Nowadays almost every program will run even on the slowest CPU (other word for Processor). The difference between a normal and a fast processor is not very big for everyday use. Most people will hardly notice any difference, except that some programs may start a few seconds quicker. Only when doing heavy computing like Photoshop, or video encoding and playing the newest games a fast processor does make a difference. For laptop owners, the most important factor is how much power the CPU uses. The more Watt per hour it uses the faster the battery will be empty.
When you decide on what processor you want in your Laptop you have to think about 3 things.
- Power usage:
The more Watt a processor uses, the faster the battery will die. Most CPUs are able to reduce their power usage on command. Under moderate usage, your processor will use only half the power. Also, as a general rule, the higher the performance of a processor the faster it empties the battery. - Performance:
A slow Processor can do everything a fast processor can do, it just takes longer. For most people the performance of the processor does not make a big difference. Only when you are playing the newest games, or encode videos you will notice a real difference between the processor speeds. - Price:
That one is obvious, when you are willing to pay extra you can expect a higher performance, but usually the power usage will also increase.
What is a good Processor?
For notebooks generally Intel processors have a better performance and use less power than AMD CPUs.
In the end it comes down, to what you want to do with your Laptop. If you want to use it on the go, take the lowest performance processor. If you will keep your notebook at home most of the time, take the best performance processor, you can afford.
How to read Processor information:
Until a few years ago there was a very simple rule to find out if the processor is fast or not. The rule was: the more GHz a processor had, the faster it was. Since about 2007 GHz are not very important anymore. Newer processors have two or 4 processors combined. It is like having to or four laptops in one chassis. This makes processors faster even when they have only 1 or 2 GHz. The only way to know if it is a fast CPU is to know what model series it belongs to.
Only if two CPUs are from the same model series you can say that the one with more GHz is actually faster.
Here is a short list of some popular Processors:
- Intel® Atom™
Very low energy consumption, very slow, cheap - Intel® Core™2 Duo
medium to high energy consumption, fast (old models), expensive - Intel® Core™ i
medium to high energy consumption, very fast (new models), very expensive - AMD Turion™
medium energy consumption, fast, cheap - AMD Athlon™
lwo to medium energy consumption, fast, cheap - AMD Sempron™
medium energy consumption, slow, very cheap

Anchor Bay DVDO HIGH DEFINITION VIDEO PROCESSOR $543.99 Say goodbye to the old standard How many standard defintion DVDs do you have in your collection at home? Buying Blu-ray versions of all of those movies seems a bit costly. But don’t worry, there’s a way you can enjoy your old DVDs, and any other standard definition source you have in your home theater, in full high definition. The DVDO EDGE is a high quality video processor and intelligent A/V hub that converts standard definition, high definition, and PC signals from up to ten sources to any HDTV resolution up to 1080p. EDGE has complete aspect ratio control that allows you to watch the way that you want, with or without the “black bars.” EDGE will also automatically sync up the audio with the video, eliminating the AV lipsync problem. So when you add EDGE into your home theater system, all your sources are converted to high definiton to make the most of your new HDTV. If you’ve got over 2 million pixels, why not use them all? It wasn’t so long ago that the standard television had a screen resolution of 640 vertical columns of pixels by 480 horizontal rows of pixels, for a total pixel count of 307,200 arranged in an almost square shape. But technology has made a giant leap forward, and now TVs are produced with a resolution of up to 1920 x 1080 with screens taking on a shape similar to what you see in movie theaters. The number of pixels in these screens has increased to 2,073,600! What that means for the viewer is that images on the screen will be shown in greater detail, creating a very realistic picture. Unfortunately, not all sources have caught up to the new standards in television production. So you’re stuck watching low-resolution footage on a screen that’s capable of much, much more. The EDGE will bring all your non-HD sources up to scratch by interpreting and upscaling the video into HD-quality. Plug your VHS player, your DVD player, and whatever other components you might have laying around, into the EDGE and watch an amazingly clear picture show up on your TV screen. The art of upscaling Creating HD images out of standard definition sources might seem like an impossible task, but with the right combination of technology, you’ll be amazed at the transformation. The EDGE contains a full complement of Video Reference Series (VRS(TM)) technologies, including mosquito noise reduction, fine detail and edge enhancement, Precision Deinterlacing, Precision Video Scaling II, Progressive ReProcessing, Progressive Cadence Detection, RightRate framerate conversion, AutoCUE-C, and Precision AV LipSync. Mosquito noise reduction Video compression is a commonly used technique to squeeze more video content onto a disc, or beam down more channels via satellite, or transmit more channels over a cable. By using video compression content providers can achieve better economies of scale and offer the consumer more video content — e.g. more channels, bonus materials, etc. The problem with nearly all video compression methods is that too |
