Some of the first questions people ask about what makes fast laptops involve the CPU and the RAM. Essentially the speed of the laptop depends on the processor within it. These days there are advancements such as the Core i7 for one instance. The design involves having two cores as oppose to just one. Obviously this will allow for much greater multitasking capabilities for the laptop. But these really fast laptops today can also take advantage of more than just increased speed they also have newer technology which can give quick bursts of speed during use.
If you consider the ratings of maximum turbo frequency, in Intel laptop processors, you can find numbers such as 3.8GHz currently. This is available when your laptop needs it, sort of like a reserve. They are still very fast without even looking at that aspect of the processor because they also are built with smart caching. As you are using the laptop, with a cache in the range of 12MB, it will simply be incredibly responsive when compared to many older laptops which simply use 1MB or 2MB L2 caches. This is merely a result of technologies advancing but laptops with these kinds of specs are not the cheapest ones out there. There really is no need to go for such a cutting edge computer unless you really want to experience that type of speed, yet they are impressive when using them for any type of task.
Most laptops are going to be categorized as netbooks, small laptops in the 10.1 inch range or standard size which is between 15 inch and 17 inch diagonal screen dimensions. However the quality of the display images as well as their speed and resolution capabilities these days, even on the cheap laptops are going to rely upon the faster processors and the increased amount of system memory (RAM). The TFT LED displays are quite common and the resolutions are comparable to those which have been on the market for some time now. The improvements are most notable in the speeds of the processors and the amounts of RAM which the lower priced laptops can handle currently. For instance, even those laptops under 300 dollars can compare relatively easily to some which are fare more expensive, at least in their speed anyway. The ability to not only multitask on a laptop but to enjoy a broad spectrum of multimedia applications are what the end goal is for most users. This versatility is what is appealing to people in the laptop market these days.
While these technological advancements are found in the broad range of laptop prices, the specifications are also going to represent their differences even though they are all considerably faster than older laptops. Looking at this progression from Pentium 4 processors for instance in the 2.0GHz clock speed range with 2MB of L2 cache, you can easily see that even one of the dual cores with 6MB of L3 cache is going to be so far beyond them that it is hard to believe. The real believers are made after they have actually experienced using one of these laptops. Still, it ultimately depends on how the laptop will be used by each individual. The used models of fast cheap laptop computers can just as easily provide the user with the perfect amount of internal components necessary to accomplish what they wish to accomplish, it just depends on what that may be and what price level the user happens to be in.
