Review Windows 7 vs Windows 10 – RAM Usage, Memory Usage, Gaming

Windows 10 benchmarks performance, in the PC world there are only 2 Operating Systems that have been delivering quality benchmarks for several years.

However, it is time to switch to Windows 10 SP2, but not just because of better security and a more trustworthy Microsoft.

Rather than looking for quick fixes by putting off necessary new operating system upgrades, consider planning the upgrade in small stages.

Windows 10’s launch left much to be desired in regard to speed when measured against Windows 7.

But in 2020 Microsoft announced a lot of security enhancements with updates to Windows, improved antivirus software and that it is completely safe to use UNIX on their devices.

Unless you use the developer tools within the preview, Windows 10 is stable with loading files, opening applications and managing windows.

Windows 7 is no longer supported by Microsoft. Windows 8.1 on the hand has either ceased to exist or has been leaving traces of itself in history’s annals.

For example, the HTC Windows Phone 8X is faring better than its Android counterpart in both battery life and speed.

The IE10 and IE11 in Windows 10 are having a better JavaScript experience than their counterparts on android.

Windows 7 vs 8.1 vs 10 – Resource Usage and Performance in 2015

PCWizKids conducted performance tests and determined which OS is more memory efficient. He used three different operating systems – Windows 7, 8.1, and 10 Technical Preview – to do his testing.

The system configuration was something like this :

  • Processor – AMD A10-6700 (Richland)
  • Motherboard – ASUS-Tek Model F285- V PRO
  • Memory : 4 GB.
  • Graphics Card – NVidia GeForce GT 740
  • Hard Disk – Minimal

Windows 7 vs 8.1 vs 10 RAM Usage

Windows 7 utilized about 800 MB of memory, which amounts to 20% of the total memory predominantly employed in the handling of common processes.

10 and 8.1 are using a total of around 700 MB settings memory, which comes to about 17%.

Although it’s early to compare the 10 Technical Preview memory usage, it’s better (i.e. 17% compared to 20%).

So with less resources it can run the processes, and the remaining could be used for gaming and other memory-intensive programs.

A recent benchmark testing using the Asus T100 machine is on the Windows 10 platform and it was found that Idle RAM usage dropped from 44MB to 29MB between Windows 8.1 and Windows 10.

Though it depends on various factors like the size of RAM, it also depends on the beta build version. For example v10041 had problems with RAM usage compared to v10130.

Similar results have been found by another user. In fact, he says that in Task Manager, the RAM usage on Win 10 was about 90% during his 8 hour work using it.

And in a different blog , a user posted screenshots comparing the memory usage of Windows 10 versus Windows 8.1.

Initially, he figured there wasn’t that much of a difference. (February 2015) But then he noticed the biggest difference between Windows 10 and Windows 8 – memory usage. windows-8-1-10-ram-usage-comparison 1

Windows 7 vs 8.1 vs 10 Bench-Mark Tests win10-b3 2 win10-b2 3 win10-b1- 4 w10-b4 5 w10-b3 6 w10-b2 7 w10-b1 8

The AIDA64 Cache and Memory Benchmark revealed the following results.

Windows 10 copy memory bandwidth usage was a little higher than the others.

Improvements with drivers have some advantages, including the flexibility to improve on existing features and managing multiple devices.

Pi has been calculated out to 1 million decimal places and Windows 10 has come out on top.

It calculated in 28 seconds, while Windows 8.1 did it in 29 seconds and Windows 7 in 30 seconds.

The CPU Queen benchmark tests the raw processing speed of a computer and in Windows 10, Microsoft’s latest version, a score of 21203 was reached.

The overall system performance test on PC-Mark 8 Home tests by Future mark showed that Windows 7 and 8 scored 2743 points.

The Windows 10 operating system was used to test the performance of these hard drive speeds.

3DMark doing the Sky Diver test, Windows 7 scored 6544 points and Windows 8.1 scored a bit less with 6483 points most likely due to the physics section requiring more CPU cycles.

But Windows 10 made improvements when compared with Windows 8.x. For example, Windows 10 offers a better Start Menu than its predecessor.

Though 7 outscored all the three, it can be seen that 5 had improvements and we can see better scores in the final versions.

Windows 10 benchmarks performance, for each of the three scenarios, the same driver drives at a steady speed.

In the Unigine Heaven Benchmark 4.0 tests, the results did not vary greatly between all of the different runs.

Although I won’t deny you’ll find many examples of games released in Windows XP also on Windows 7, the later operating system was built to better support games and graphics.

While the FPS scores were very similar at around 503, we’ve not yet seen any improvements to driver accuracy. If one has already upgraded their hardware, they will have a clearer advantage over those who haven’t done so.

Windows 10 vs 8.1 vs 7 Gaming Performance

Tech YES City compared the performance of 3 commonly used games on Windows 7, Windows 8.1, and Windows 10 Technical Preview.


  • 5820k @ 4.2ghz / 3.3ghz cache ratio.
  • DDR4 Memory at 2133 default speeds.
  • GTX 970 at default speeds.
  • X99S SLI Plus MSI Motherboard

These results were obtained from the following games and software (Battlefield 4, Skyrim, Arma 3) / Adobe CS6 Premiere pro benchmark (rendering times) and a start up (boot) time test.

The final conclusion was that all the three games fared well. They were similar in all the three operating systems.

Windows 10 benchmarks performance, but there are some advantages that are worth mentioning for two of the games in Windows 8.1.

With the upcoming release of Direct X 12, Windows 10 may only continue to improve. The title Crysis 3 is known to have some issues on Windows 10, but the performance was still consistent with that of 7 and 8.1’s.
