The next step is to perform the process of upgrading your laptop’s processor step by step. You will follow these instructions to complete a few simple but technical steps. If you follow these steps precisely, you’ll achieve your goals.

Check The Compatibility Of The CPU And Motherboard

It is important to check the compatibility between the CPU and motherboard before upgrading the CPU. The processors supported by your motherboard are limited.  Your first step should be to check it out. In this process, we will only be interacting with these three components. A useful tool from Intel makes it easy to find the best motherboard or CPU for your needs.

Check The Compatibility Of The CPU And Motherboard

There are also other applications you can use such as CPU-Z that will tell you your processor type for you. The processor details can be viewed by going to your computer and selecting this PC, right-clicking and selecting Properties or searching online.  This motherboard’s CPU list can be found by searching Google. Depending on your budget for upgrading, you can choose from i3, i5 or i7 processors.

The motherboard socket type should be checked before you upgrade the motherboard. A socket type is determined by its architecture.  It is possible to replace the processor if there is no problem with the socket type. You can also upgrade your socket to something more powerful.

You could upgrade your laptop further by buying these GPUs for under 150 rupees and upgrading the RAM and GPU.  Your new processor will be able to perform better with this added performance. The RAM of a processor should be as powerful as possible.

The Core Hardware Differences Between CPUs, GPUs, and TPUs

Find A Compatible Processor To Upgrade

You will then need to find a processor that will work with your motherboard. You should know the differences between i3, i5 and I7 processors before deciding which one to choose. They will guide your decision. In terms of performance, the i7 CPU is superior to the i5. In addition, the i5 is faster than the i3. The reason for the difference in performance needs to be explained in more detail.

It’s important to remember that i3, i5 and i7 refer to the relative processing power of every Intel Core family processor. The number in the name of the CPU does not indicate how many cores it has or how well it performs. There are no seven cores in Core i7 CPUs nor are there three cores in Core i3. 

The number of Intel technologies integrated into an Intel Core CPU determines its family. These include core count, clock speed and cache size. You are considerably less likely to find Turbo Boost and Hyper-Threading in an i3 CPU than in an i5 or i7 processor. They give buyers an indication of the performance of each class of Intel Core CPU.

  • It is possible to perform basic tasks with an Intel Core i3 processor.
  • In most cases, an Intel Core i5 is a good choice.
  • It provides superb performance for even the most demanding tasks.

A processor’s name does not always indicate its performance. A few i5 processors can beat older Intel i7 processors in performance.  The performance should not be judged by its name. In its name, the number serves as a guide to understanding the processor’s performance and core family. There is also a way to group Intel’s Core i3, i5 and i7 processors by their intended devices.

There are some for laptops and others for desktops. The main difference here is the amount of power the CPU uses as mobile devices are often required to reduce power usage. Your processor will perform tasks faster if it has more cores. A PC with multiple cores is also more suitable for multi-threading projects such as video games and web servers.

One exception is the 8th Gen Core i3 CPU from “Coffee Lake,” the only Core i3 CPU with only two cores. Because they are built to be more cost-effective than powerful i3 processors offer lower performance for a lower price.  This type of component can usually be found in PCs intended for budget-conscious markets where a low price overrides the need for more performance. Cheap gaming laptops with fewer cores or older processors are more likely to use the i7 processor which has more cores than the i5. 

Changing the Processor

Changing the Processor

If you are unsatisfied with your existing processor, it’s time to upgrade it. The purpose of this tutorial is to teach you how to upgrade the processor in a laptop. The steps below explain how to dismantle your laptop:

  • Connect the antistatic strap to a metal surface and yourself. You can use a radiator as an earthing point. 
  • You should unplug the heatsink or cooler from the processor if any cords are in the way.
  • The cooler needs to be removed carefully after the screws are removed. In a solution, soak a lint-free cloth to remove the thermal paste.
  • The worst compound should be wiped off the CPU to prevent moisture from getting onto the motherboard.
  • You should repeat the procedure for the cooler/heatsink.
  • After applying the purifier, you should apply a clean cloth to the CPU and the heat sink.
  • You can remove the old CPU by releasing the lever holding it, raising the flap and pulling it out. It would help if you lifted it by the corners. 
  • Remember the golden arrow in the bottom right corner to install the new processor while installing. In the same way that the old processor was removed, the new one should be installed.
  • Be careful and soft when installing the new processor.
  • The flap should be replaced and the lever should be gently reinserted.
  • The new thermal paste should be applied now.
  • For the paste to cover the entire processor, it must not spill over the edges.
  • The CPU cooler should be replaced, reconnected and tightened.
  • Ensure that all cables are plugged in again.

A processor upgrade will improve the performance of your laptop. You will notice the improvements more easily since they are not drastic.  There will be no more waiting for your laptop to start up since the booting speed will be increased. Cooling occurs without making any loud sounds. There will be a significant increase in the speed at which MS Word, MS Excel and other applications start.

Your laptop will be more capable of playing games. There will be no problems running modern high-graphics games. Your laptop will have an increase in battery life of about 15 minutes.  This software allows you to transfer files quickly as well as multitask easily. The improved performance of your laptop will surely increase your overall productivity.

Necessary Factors to Consider While Upgrading

The decision to upgrade from one core to another and add a higher core involves several factors. The following are just two important things to consider but we will explain them more clearly for clarity. There must be several similarities between your old and new processors except for a few small differences.

TDP Rating

It would help if you focused on TDP first. To replace your old processor, you would want to find one with the same TDP rating. This results in the processor generating almost the same amount of heat. Your laptop cooling system can dissipate that generated heat. 

If you add a processor with high TDP, it’ll generate more heat. Your laptop would not be able to dissipate the extra heat and could cause damage to your laptop. This factor is crucial as adding an incompatible CPU could worsen the condition. 

Generation & CPU Cores

In contrast to desktop computers, laptops cannot be upgraded with higher-generation CPUs. In other words, you must select an i7 processor with the same generation as your i3. The main purpose of upgrading is to run high-end software and multitask. The only option would be the i7. 

A laptop processor with more cores will perform faster. You can multitask and run programs more quickly with the Core i7 processor because it has more cores than the i3. It is therefore not advisable to upgrade to higher generations as it could risk your money and laptop. 

Before And After Laptop Processor Upgrade

  • The bootup time on my Windows 10 used to take 8 seconds, from the start-up logo until you reached the login screen. There is now a 5-second delay!
  • Cooling sounds don’t come from the laptop fan. It used to be more common before and is now very rare.
  • The opening of MS Word, MS Excel etc is much faster.
  • There is a greater sense of responsiveness and fluidity when playing games such as Counter-Strike GO or MK4 11 – Komplete Edition.
