GPU UPGRADE


The CPU does its job well, but there are some tasks that it isn't suited for. One of these is rendering graphics. Creating complex visuals quickly enough to provide a smooth experience requires massive parallelization. This is why a laptop CPU has one to four cores and a laptop GPU has between 2 and several hundred.

If you're like to play 3D games at high detail settings you'll need a discrete GPU. This is a separate component placed in the laptop to boost performance in games. Nvidia and AMD are the names well known in computer GPU.

Below is the list of latest GPUs available for desktop in the market(27-01-2017):
  1. AMD Radeon Pro Duo 
  2. NVIDIA Titan X (Pascal)
  3. NVIDIA GeForce GTX 1080

RAM UPGRADE


RAM aka Random Access Memory, has always been considered important by enthusiasts. The purpose of RAM is similar to the purpose of your own short-term memory. It provides the computer with a space to load information useful for a current task. The more RAM you have, the more information you can store.
There's usually a limit to the amount of information you need to store. 32-bit processors have a limit of 4 GB and 64-bit can support much more. During every-day tasks, and even some demanding tasks, you don't need more than four gigabytes of RAM. Adding more is only useful in certain situations. For example, people who edit HD video, play games frequently might need more memory.

 RAM is one of the few components that most laptops allow a user to upgrade. However the specifications are to be looked a bit careful as the RAM varies with voltage and frequency. The usual frequency stays between 800MHz-1600 MHz.

RAM MANAGEMENT

RAM or Random Access Memory is an essential component that provides temporary storage space for the programs to be executed in processor. Typically, the amount of RAM installed on your device varies from 512 MB to 32 GB depending up on the performance need. For a typical user with his normal functions such as browsing internet, using office 2-4 GB RAM is enough. More RAM available for work is always desired.
There are couple of ways you can increase the amount of RAM in the system.

  1. Buy a new RAM module and install it in your system.
  2. Terminate unnecessary processes in the task manager.
  3. Close unnecessary programs.
  4. Remove unnecessary shortcuts and icons in desktop.
  5. Clear temporary cache.
  6. Use a memory management application.
  7. We recommend to use a trusted software to manage the memory.

Alternate method using software:

You can use the Smart RAM feature in Advanced System Care.

PROCESSOR UPGRADE


The CPU is the brain of the computer. It performs all the calculations and computations necessary for programs to run. These calculations take place within millionths of a second. As the programs get more complex, the time required for the calculations will also increase. Processing a photo may take a second or two but encoding an hour-long video will take an hour or more.
Buying a faster processor can significantly decrease the time these tasks take. For example, a dual-core Core i5 can batch process videos three to five times quicker than an Atom processor.
Here are a list of processors currently available in the market. Choose the one that best suits your needs:
Basic Processors (Can handle web surfing, document writing, etc...)
  • AMD Turion
  • Atom
  • Intel Celeron
  • Fusion E-Series
Entry Level Processors - (Suitable for entertainment and everyday tasks)
  • Intel Pentium Series
  • AMD A-Series
  • Intel Core i3
Performance - (Suitable for resource intensive tasks like gaming)
  • Intel Core i5
  • Intel Core i7 (dual-core)
  • Intel Core i7 (quad-core)
High-End - (The fastest currently available)
  • Intel Extreme Edition
 If you use only the web and basic productivity applications like Word, Excel, PowerPoint etc. a basic processor will suffice. Everyone else will need at least an entry-level or performance CPU.

PC SELECTION


Four factors to take care while selecting your brand new laptop are
  1. Performance
  2. Portability
  3. Screen Size
  4. Thickness

1. Performance
Performance is a concern for most people in the hunt for a new laptop. But the fact is that most users are not aware of what should be the performance needed. If you go behind performance, you will end up in expensive laptops. But the fact is that, you may not be using its full potential in its lifetime.
Here are some common tasks that will benefit greatly from more powerful hardware.
  • Audio/Video de/encoding and editing
  • Photo editing
  • Programming
  • Editing large spreadsheets, documents and PDFs
  • Games
Some people don't frequently perform any of these tasks, and if that sounds like you, a basic laptop should suffice.
Users who want a computer that can handle several of these workloads at least several times a week, on the other hand, should start thinking about the benefits of an Intel Core i5 or i7.

2. Portability
Battery life is a commonly quoted statistic that holds just as much weight as a computer's performance. Usually the systems are capable of providing 80 % of the battery backup as promised by the manufacturer. But for intensive workloads such as gaming it could drop to 40-50 %. But the good news is that there are many laptops which will retain the battery for up to 5 hours with ease. Some ultra-books can even achieve up to 13 hours.

3. Screen Size
Display size of laptop varies from 10.1" to 18.4". The size of the display naturally determines the size of the rest of the laptop, which in turn determines what that laptop can do.
Let's break down laptops into categories based on their display:
  • 10.1" - Netbook. Extremely portable, but difficult for people with large hands. The small size of the chassis limits hardware to CPUs with poor performance.
  • 11-12.9" - Small ultraportable. Still easy to carry, and easier to use. Faster hardware can fit, but there are still limitations on performance.
  • 13-14.1" - Large ultraportable. Easily fits in all but the smallest bags, but difficult to use on an airplane and most forms of public transport. CPU performance can be excellent, but GPU performance iGIMs often lacking.
  • 14.2-17" - Mainstream laptop. Somewhat portable, but it won't fit in some bags. Performance is solid and some models offer excellent GPUs. A good all-rounder.
  • 17" or more - Desktop replacement. Won't fit in all but the largest backpacks. The best mobile hardware will fit, including high-performance GPUs. Most gaming laptops and high-end multimedia laptops are in this category.
4. Thickness

Products with a thick profile are considered outdated or unattractive, and sometimes ignored entirely. Now a day’s Ultra-books which has a thin profile has become trendy. Thin laptops are attractive, weighs less, portable. But thick laptop on the other hand can fit in high performance hardware inside. It also has better cooling mechanism and better battery backup.

HDD / SSD UPGRADE

We all use hard disk drives as storage solution for our computers. One thing most people overlook is that, hard disks have a significant part to contribute towards the performance of your computer. A sluggish hard drive will slow you down no matter how much faster your processor is or how much RAM you have installed.
There are mainly two types of hard drives available: Mechanical Hard Disk Drives (HDD) and the Solid State Drives (SSD).
HDD’s come in two varieties:
  • Hard disks with 5400 RPM spinning speed.
  • Hard disks with 7200 RPM spinning speed.
Higher speeds tend to offer better file transaction speeds.
Mechanical hard drives have a read/write head which has to move to the correct location on the disk before the reading of data begins. Hence it is slower.
SSD’s on the other hand do not have any physical moving parts. This helps to eliminate the extra read time and greatly improves the application loading time. But SSD’s are much more expensive than a mechanical drive. Hopefully they’ll get easily affordable in the future.
Some advantages of SSDs compared to HDDs are

  • Way faster than HDDs.
  • More reliability as there are no moving parts
  • Less power consumption with no noise
  • Low heat generation.

COOLING EFFICIENCY


Cooling is an important factor in the performance of your computer. The cooling system varies from a simple fan based system to liquid based system. The foam factor of the system also contributes towards efficient cooling. During use, your computer produces heat. This heat increases the resistance of components inside and thus affects the performance.
Some ways to increase the cooling efficiency are:

  1.   Clear the air vents. Usually after a period of usage the vents will be clogged with dust. Unclogging the vent will restore the efficiency of cooling. It can be done by opening the system as a whole or you can use a hair dryer / vacuum cleaner.
  2. External cooling pads are available in the market. This helps in keeping the system cool. Gaming is a pretty resource intensive process. Hence, a lot of heat will be generated. If the cooling system installed in your computer is not able to keep up with the amount of heat generated, a cooling pad may help.

SELECTING THE RIGHT BATTERY FOR YOUR PC


Selection of a battery is directly linked with your back up needs. Commonly available batteries for laptops are of 4-cell, 6-cell, 8-cell and 12-cell. Batteries with 4-cell being are having lowest power backup and are least expensive whereas 12-cell will be having highest backup and are highly expensive.
The battery backup depends upon many factors. Some of the prominent factors are:
  1. Processor power utilization.
  2. Other hardware such as Memory, HDD power utilization.
  3. Screen size and brightness used.
  4. The condition of the battery.
  5. Cooling ability of the laptop.
  6. OS and BIOS dependency.
  7. Charger power rating and battery type.

Ensure compatibility of battery with your system. You can check the price and model of battery from most of the manufacturer’s website. The purchase can be made from the manufacturer’s website or from an e-commerce website such as e-bay, amazon etc.
