(Next, know your specs. These 3 are the most important to look up for when purchasing a laptop. make sure to look for these 3 when making decision.
AMD E Series or Intel Pentium CPUs is claimed as the least expensive system on the market, due to it often struggle in handling serious productivity or media tasks however can handle web surfing. Intel Atom processors are also in the same class which is low-performance, but offer long battery life. To simplify, everything AMD has launched in the past five years has been too late and too slow. Most tablet / laptop hybrids use Intel’s Core M CPU, which is faster than Atom but not as quick as Core Series (Core i3, i5 and i7). If you ever had a Core i3, Core i5 or Core i7, try to get the latest version which is Intel 5th Generation (aka Broadwell) as of early 2015.
Core i7: Intel's top-of-the-line consumer processor. The choice of "power users" like hardcore gamers, graphic designers, photographers and videographers. It excels at serious multitasking and high-demand multimedia creation for projects in 3D or high definition. It is the most brilliant system ever.
Core i5: Mid-grade Core processor and one of the most common Intel processors currently in use. Powerful enough for most computing tasks, and multitasks well so you can stream the big football game while looking up stats and sending e-mails.
Core i3: The entry-level Core processor, more than adequate for everyday e-mail, Internet and productivity tasks. It's also fine for common activities like listening to music.
Core M: A processor designed for ultraslim devices, providing plenty of power for day-to-day surfing and e-mailing without being a major drain on battery life.
Performance wise, do not go for less than an Intel Core M for thin systems or a Core i3 CPU /AMD A Series for mainstream laptops. If you willing to spend more, demand for at least an Intel Core i5 CPU, which is capable of increasing its clock speed enthusiatically when you need more performance. Power users and gamers should settle for no less than Core i7 sytstem, preferably a quad-core chip.
Memory matters also known as RAM, even the cheapest notebooks have 4GB these days so don’t settle for less. If you can get a system with 6 or 8GB, you’ll be better prepared for high-end applications and lots of multitasking. Gamers and power users should look for 16GB of RAM.
- Hard Disk Drives
Traditional, mechanical hard disk drives are the most common type of storage because they're fairly inexpensive and offer huge capacities. Significantly, it is also added up to a laptop's weight and thickness, and generate both heat and noise as well as lots of moving parts to your system. HDD can be found in diminishing number of laptops. They come in two standard speeds: A 5400 rpm (revolutions per minute) drive is adequate for day-to-day Web surfing, e-mailing and document creation, but a 7200 rpm drive transfers data more quickly and may be worth considering if you regularly work with large files or when editing video or playing games. Look for at least a 320GB hard drive, even in a budget system.
Solid-state drives, also known as SSDs (or, in Apple's case, "flash storage"), are many times faster than hard disk drives, but typically offer far less capacity (usually 128 to 256GB). SSDs also offer tremendous advantages in physical size, weight and power efficiency, along with negligible heat production and noiseless operation, making them an ideal choice for ultraslim, ultralightweight laptops. And unlike HDD, SSDs have no moving parts to wear out. However, SSDs sometimes could cost quite a bit more than traditional hard drives(offer larger storage capacity), but they dramatically improve performance. You’ll enjoy faster boot times, faster resume times, and faster application open times. Plus, because SSDs don’t have moving parts such as mechanical drives, failure is much less of an issue.
