While there are a plethora of browsers to choose from, it’s the likes of Chrome, Edge, and Firefox that have managed to carve out a rich fanbase for themselves.
If we talk about the offering from Google Chrome, then its handy cross-device and support for numerous extensions and add-ons have made it the go-to choice for many users.
Along the same lines, it has also benefited from the first-move advantage, i.e., being one of the first names to make their entry in this domain. As far as Mozilla Firefox is concerned, well, it prides itself on being the most secure and private browser out there.
Then Microsoft’s revamped Edge browser offers you all the Chromium features but without being a heavyweight on your system. However, the performance metric for all these three browsers has always been up for debate.
While Chrome is usually documented as the most resource-hungry browser out there, there haven’t been any numbers to justify this claim. Edge has been claimed to be the least resource-hungry browser along the same lines, whereas Firefox occupies a middle ground.
Well, you might have already read these reviews across many different forums, but we decided to put them to the test. This article has performed a detailed performance review for Chrome, Edge, and the Firefox browser, based on different parameters.

Browser Testing Environment
The test was carried out on a Windows 11 OS, and only two apps were running- the test browser and the Task Manager. Moreover, all three browsers were set to their default configurations- except for third-party extensions.
With that said, each of these browsers underwent four different tests, namely:
- When no tabs were running in the browser.
- Incognito/Private Mode browsing session with all the extensions disabled.
- When five tabs were running (same across all the three browsers).
- When 20 tabs were running (same across all the three browsers).
We then judged them on the CPU Usage and Memory Consumption data taken from the Performance tab of the Task Manager.
So what were the results, and who came out on top in all these four tests? Well, without any further ado, let’s check it out!
Google Chrome Performance
Here are the results of the performance that we carried out on the Chrome browser.
No Tabs Opened
When we opened no tabs in the Chrome browser, the CPU usage was around 4-5%, whereas the Memory consumption clock at 62%
Incognito Mode
Using the browser in an Incognito Mode resulted in the CPU Usage of 3-4%, whereas the memory usage percentage was 62.
Running Five Tabs
When we opened five different tabs concurrently, CPU usage and Memory witnessed only a slight increase. The former was recorded at 5% whereas the latter stood at 70%.
Running Twenty Tabs
Running twenty different tabs at once was enough to push the CPU Usage to 12-14%, and the Memory consumption also increased all the easy up to 92%.
Chrome Performance Results
Following is the results data for four tests performed on Google Chrome:
| Chrome Running | No Tabs | Incognito | 5 Tabs | 20 Tabs |
|---|---|---|---|---|
| CPU Usage (%) | 4-5 | 3-4 | 5 | 12-14 |
| Memory (%) | 62 | 62 | 70 | 92 |
Microsoft Edge Performance
Here’s how the Chromium build of the Microsoft Edge browser performed across the four tests we conducted.
No Tabs Opened
When the Edge browser didn’t have any opened tabs, the CPU Usage was a meager 3-4%. Likewise, the Memory percentage was also on the considerably lower side, i.e., 68%.
InPrivate Mode
Using Edge in its Private Mode gave out similar results as to when no tabs were running. The CPU usage stood at 3%, and Memory consumption was at 68%.
Running Five Tabs
When we ran five tabs at once, there wasn’t much increase in the CPU usage; it oscillated between 4 to 6%. However, the Memory consumption was somewhat on the higher side, at 85%.
Running Twenty Tabs
The browser recorded increased CPU and Memory consumption when 20 tabs were running together after a rigorous test. The former was found to have values between 7 to 10 %, whereas the latter was close to touching 90%.
Edge Performance Results
Following is the results data for four tests performed on Microsoft Edge:
| Microsoft Edge | No Tabs | Private | 5 Tabs | 20 Tabs |
|---|---|---|---|---|
| CPU Usage (%) | 3-4 | 3 | 4-6 | 7-10 |
| Memory (%) | 68 | 68 | 85 | 89 |
Mozilla Firefox Performance
The privacy enriched Firefox was also put to the same tests as the other two, and here are its results.
No Tabs Running
When Firefox wasn’t running any tabs, it didn’t consume much system resources. We found it to have around 3% CPU Usage and just 63% memory consumption.
Private Mode
Running Firefox in the Private Browser window gave a mixed result (in comparison with our earlier No Tabs Running test). While the CPU usage was around the expected 3-4% lines, the memory utilization slightly increased to 67. It was even when all the extensions stood disabled.
Running Five Tabs
There wasn’t much increase in the CPU Usage when the browser had five tabs running at once. However, Memory consumption witnessed an increment of 10% (from 63 to 73) compared to when the browser didn’t have any opened tabs.
Running Twenty Tabs
When the number of tabs increased to 20, so did the CPU and the Memory Usage. While the former spiked up to 10%, the latter also achieved a higher 90% value.
Edge Performance Results
Following is the results data for four tests performed on Mozilla Firefox:
| Firefox Running | No Tabs | Private | 5 Tabs | 20 Tabs |
|---|---|---|---|---|
| CPU Usage (%) | 3 | 3-4 | 3-4 | 7-10 |
| Memory (%) | 63 | 67 | 73 | 90 |
Test Results Comparison
The data of all the four tests performed on Chrome, Edge, and Firefox made for some pretty interesting observations. Let’s dive deep into the results of all these four tests and see what they have in store for us.
| Chrome | No Tabs | Incognito | 5 Tabs | 20 Tabs |
|---|---|---|---|---|
| CPU Usage (%) | 4-5 | 3-4 | 5 | 12-14 |
| Memory (%) | 62 | 62 | 70 | 92 |
| Edge | No Tabs | Private | 5 Tabs | 20 Tabs |
| CPU Usage (%) | 3-4 | 3 | 4-6 | 7-10 |
| Memory (%) | 68 | 68 | 85 | 89 |
| Firefox | No Tabs | Private | 5 Tabs | 20 Tabs |
| CPU Usage (%) | 3 | 3-4 | 3-4 | 7-10 |
| Memory (%) | 63 | 67 | 73 | 90 |
When we opened no tabs in the first test, the CPU usage was the maximum in Chrome, but only by minuscule margins. However, it consumed the least resources in the Memory domain, with Firefox occupying the second spot and Edge coming at a distant third.
Next up, in the Private/Incognito Mode, all the three browsers had around 3-4% CPU Usage. Still, Chrome again came out with flying colors in the memory consumption with 62% instead of approximately 67% for the other two.
When we had five tabs running, the browser from Google outdid its competitor in the Memory Usage section. Whereas Edge had clocked over 85%, Firefox was around 73%, whereas Chrome was touching 70%. Firefox sneaked in front of Chrome in the CPU Usage test, and Edge again had to settle for the last spot.
But when we tested the three browsers to the extreme, Microsoft was finally able to taste the winner’s medal, but only by just a whisker.
Both Edge and Firefox had similar results in the CPU Usage (7-10%), but it ‘edged’ out its counterpart by a single percent and Chrome by a comfortable 3% margin.
Bottom Line: Best Browser Performance
Going through all the numbers, we might soon put the myth that Chrome is the most resource-hungry browser to rest.
Well, the numbers don’t lie, and hence it should be an easy decision to crown as the ultimate Chrome of this performance review test. But before you ditch the Edge or Firefox browser for Chrome, there are a couple of things to keep in mind.
First off, the test was carried out in an experimental environment, with only two apps running. However, there might be many instances when you would have multiple apps concurrently running at once on your PC. And in those scenarios, the results might be slightly different. Well, we tried that as well.
In that case, it was a near-impossible task to switch over to another app in Chrome (especially when it had 20 tabs opened). However, Edge did it with ease, and Firefox also didn’t cause much of an issue. But even then, let’s give some credit to Chrome for performing quite decently in all these four tests.
On that note, we round off this performance review between Chrome, Edge, and Firefox.
