If you are buying a refurbished laptop, this is probably the most important comparison you will come across
i5 7th generation vs i5 8th generation
At first, it doesn’t seem like a big deal
Just one generation difference right
But in reality, this is one of the biggest jumps Intel ever made in laptop performance
And this is exactly where most people make a mistake
They try to save a little money by choosing 7th gen without realizing how much difference it actually makes in daily use
So instead of confusing you with technical terms, let’s break this down in a real, practical way
Understanding the Core Difference
Let’s keep this simple
i5 7th gen laptops usually come with 2 cores
i5 8th gen laptops usually come with 4 cores
That means the 8th gen literally doubles the processing power in many cases
And this is not a small upgrade
This is the main reason why 8th gen feels much faster in real life
Performance CPU and RAM
This is where everything changes
In 7th gen
You get dual core processors
Limited multitasking capability
In 8th gen
You get quad core processors
Much better multitasking
Because of this difference, real world performance can improve massively
Some tests show up to 50 percent to even 90 percent improvement depending on the task
Now let’s translate that into real life
If you are
Opening multiple Chrome tabs
Using Excel
Watching videos while working
Switching between apps
7th gen will start to feel slow
8th gen will feel smooth
That is the real difference
Multitasking Real World Example
Let’s say you are doing this
10 to 15 Chrome tabs open
YouTube running
Excel or Word open
Zoom meeting in background
On a 7th gen laptop
You will notice lag
System feels heavy
Switching apps takes time
On an 8th gen laptop
Everything feels smoother
Apps switch faster
Less frustration
This is because more cores handle more tasks at the same time
Single Core vs Multi Core Performance
Here is something interesting
If you are doing very basic tasks like opening one app at a time
The difference is not huge
Single core performance is only slightly better in 8th gen
But once multiple tasks start running
8th gen pulls far ahead
That is why people feel a big difference in daily usage
Speed Comparison in Real Tasks
Let’s look at some real scenarios
Opening apps
8th gen opens apps faster because of better processing and optimization
Excel work
Large spreadsheets run much faster on 8th gen
Some tests show around 50 to 70 percent improvement in heavy Excel tasks
Video editing or conversion
7th gen struggles with heavy tasks
8th gen handles them much better
Even basic things like system startup and responsiveness feel quicker
Graphics and Everyday Use
Graphics is not a huge difference but still slightly better in 8th gen
Better integrated graphics performance
Smoother video playback
Better handling of light editing
But don’t expect gaming level difference
This is still for basic to moderate usage
Battery and Efficiency
You might think more power means more battery usage
But 8th gen is actually more efficient
Because of better architecture
So in many cases
You get better performance
And similar or even better battery life
That’s a win win
Real Life Usage Difference
Let’s make this very practical
If you choose i5 7th gen
It works fine for
Basic browsing
Watching videos
Simple office work
But once you start multitasking
It feels slow
If you choose i5 8th gen
It handles
Multitasking
Office work
Freelancing
Coding
Light editing
Much more comfortably
That is why most people prefer it
Biggest Truth Most Sellers Won’t Tell You
Here is something important
An i5 8th gen is often faster than even an i7 7th gen
Yes that’s true
Because more cores matter more than branding
Real world tests show i5 8th gen outperforming older i7 processors by a big margin
So don’t get confused by i5 vs i7
Generation matters more
Refurbished Laptop Value Comparison
Now let’s talk about money
In the refurbished market
i5 7th gen laptops are cheaper
i5 8th gen laptops cost slightly more
Usually the difference is around a few thousand rupees
But the performance difference is huge
So the real question is
Do you want to save a little now or avoid frustration later
Most people who buy 7th gen end up upgrading sooner
Who Should Buy i5 7th Gen
Go for 7th gen only if
Your budget is extremely tight
Your usage is very basic
You just need a temporary laptop
Otherwise it is not future proof anymore
Who Should Buy i5 8th Gen
Go for 8th gen if
You multitask
You use Excel or office tools
You attend meetings
You want smooth performance
You want a long term laptop
This is the safest choice today
Common Mistakes to Avoid
Choosing 7th gen just to save a small amount
Thinking i7 7th gen is better than i5 8th gen
Ignoring number of cores
Buying without SSD
Not checking RAM
These mistakes affect performance more than anything else
Expert Tips Before Buying
Always prioritize processor generation
Choose at least i5 8th gen if budget allows
Get minimum 8GB RAM 16GB if possible
Always choose SSD
Do not get confused between i5 and i7 without checking generation
Buy from a seller that offers warranty
FAQs
Is i5 8th gen much better than 7th gen
Yes the difference is significant especially in multitasking
Is i5 7th gen still usable
Yes for basic tasks but not ideal for long term use
Is i5 8th gen future proof
Yes it is still a solid choice for most users
Why is 8th gen faster
Because it has more cores and better architecture
Is it worth paying extra for 8th gen
Yes the performance difference justifies the price
Conclusion
If you were expecting a small difference between i5 7th gen and 8th gen, it is not small at all
It is one of the biggest performance jumps in recent laptop generations
7th gen is basic and limited
8th gen is smoother and more capable
So if your budget allows, the choice is very clear
Go for i5 8th gen without overthinking
Because in daily use, that extra performance makes a much bigger difference than saving a little money upfront. Shop i5 laptops like the Dell Latitude 5480 (7th Gen) and HP EliteBook 840 G5 (8th Gen) at Inspire Connectivity.
