Introduction

With the recent news Windows 7 approaching the beginning of the end of its life cycle and Windows 8 is phased out in favour of the updated Windows 8.1 I decided to run a little test, to find out which of the two most modern Windows OSes performaned the best.

Many of us enthusiast refuse to upgrade from Windows 7, while most new system builders simply having no choice but to go for Windows 8.1, is either side losing out here? For the best performance should the old Guard on Windows 7 upgrade, or should the newcomers on Windows 8.1 consider searching for an increasingly rare Windows 7 liscence key? Lets find out.

Test Setup

Intel i5 4670k
Gigabyte Z87 G1-SNIPER
Sapphire R9 290
Team Extreem DDR3 2133Mhz 12GB
Samsung 830 128GB SSD
CoolerMaster Silent Pro 1000w
Custom Water Cooling loop
Modified Silverstone RV03
Windows 7 & 8.1
AMD Catalyest 14.7 Drivers


Test Procedure

While conducting this testing all components will be ran at stock speeds and both Operating Systems will be ran on the Same Samsung 830 Drive from a fresh/clean instal.
The only things that will be installed on the system will be the AMD 14.7 Driver, the programs that I will be using to test and every update that Microsoft automatically downloaded and installed, this is to leave no possible bload ware or any other performance reducing programs to be present.


System Benchmarks

Cinebench

We will start with Cinebench, a benchmark which from my experiences can have it’s scores drastically altered by even the most minor of backround applications has scores which are nigh identical on both Windows 7 and 8.1. This could mean that under the hood both operating systems perform very similarly, but lets see a few more benchmarks.

wPrime

wPrime shows a similar story to Cinebench, both have nigh identical performance numbers with only .6 and .02 second difference between 1024 and 32 times respectively.

PCMARK

Again in PCMARK we have the same story almost identical scores, with not even 50 PCMARKs between each OS. I think we can conclude that performance is the same throughout, but first we will need to see if this also applies to gaming.

3DMARK

We will start the gaming tests with 3DMARK, and yes you’ve guessed it nigh identiacal performance. Windows 8.1 came out slightly ahead in the Fire Strike Benchmarks, but 7 maintained a slight lead in all others.

CATZILLA

Moving onto Catzilla the differences are again non existant, it simply has to be said that performance wise these tests these operating Systems are identical.

Gaming Benchmarks

We will finish with a few in-game benchmarks, here regardless of the game or resolution the Games perform identically regardless of OS. Even when trying AMD’s Mantle, a beta API, neither OS can even beat the other by more than .1 of a FPS.

Conclusion

The conclusion here is simple, when comparing the performance of these Operating Systems neither reign supreme, not even a single scenario can give either a solid win over the other. It is almost like both are the same thing underneath, which we know isn’t true.

The only advice that can really be given here is buy the OS which you are most used to right now if you are building a new system as performance wise they are nigh identical in all tests. In my opinion there is no sense learning a new OS if there is literally nothing to be gained by it at present.

I did not conduct boot time testing and I do not plan to, simply put if you want a faster boot time buy an SSD. Any seconds saved on a boot with a different OS is easily cancelled out by the time taken to learn how to use it. Who cares if your boot time is a second faster if you trip around on the metro for a minute afterwards, or if you otherwise cannot easily navigate the OS. This test was about performance, where I have conclusively proven there are no differences.

Thank you all for reading this and Good night.

(also I know the images say 8 not 8.1 and some have data numbers missing, I will fix this tomorrow.)
 
Thanks for the nice thoughts and for the time you've been spending comparing both OS. I was starting to think about upgrading to 8.1 but I'll stick with 7 for a while :p
 
Battlefield 3/4 seems to have noticable performance improvements when going from windows 7 to 8/8.1. You should try benchmarking that
 
Frame times are better in windows 8.1 and 8.1 has better 4K support but those are pretty much the only things 8/8.1 has over 7 and they are miniscule.

And as RamcoOC stated the Battlefield games do feel smoother when on 8.1, Less stutters etc...
 
Nice report there can see Win 7 leading the way slightly in a few of the things, a lot more so than Win 8.1 does.

Luckily for me I have several Win 7 keys, for all versions of it (technet subscription that had expired now) but unfortunately I have only 1 Windows 8 key (bought through the upgrade when Win 8 first come out), but I always seem to stick with Win 7 on my machines, I am really put off Win 8 / 8.1 because of Metro, and no start button without things to modify the system.

I haven't yet tried how Windows 8 / 8.1 will run on my new rig, so I am debating whether to install Win 8 Pro and do all the upgrades on it to see if it worth me running it as my full time OS.

If someone can recommend a good Start Menu replacement program (preferably free so I can test it out with Win 8.x), then I will get to testing it out some point today on this machine.
 
its a shame you couldn't show things from the AMD side for CPU performance, the bulldozer architecture gains a fair bit in performance on windows 8 compared to 7
 
Great performance testing. I thought 8.1 would have much better performance, but clearly it hasn't. Oh well, theres no going back now ;)
 
Ok on lunch break so will try to answer a few questions

Why are W7 keys hard to get? Is it not the case that all copies of W8 Pro have downgrade rights.

JR

I was unaware of "downgrade rights" for windows 7, if they do exist then Windows 7 Isn't hard to come by. I recently had to source a truck load of licence keys for pretty much my whole family after XP ended.

I'll look it up when I get home.

It's a shame, but I doubt the gains will be that high. Then again without testing I don't know.
I'd love to have the chance to test AMD CPUs on this, but the FX 8350 is nearly 2 years old isn't it? I wonder if a A10 7850 could even compare to the i5, even if heavily overclocked? It would be an interesting test.

I've heard of the downgrade rights, but I thought that it was just a case of being able to run the windows setup through Windows to install, does that mean that the win key for 8 / 8.1 is all you need then and windows 7 will accept it?
 
From reading the OEM speil that on the M$ partner network, I not certain about the key, it doesn't make it clear windows 8.1 or windows 7.

It will only downgrade win 8.1 pro to windows 7 pro or vista business editions until a time where you want to run windows 8.1 again.

Steps for an end user to downgrade Windows software
To downgrade Windows 8.1 or Windows 7 software, end users must:

Purchase a PC preinstalled with Windows software.
Accept the Microsoft Software License Terms.
Perform the downgrade process to the eligible downgrade product using the media/key from a genuine, previously licensed OEM or retail product.
The downgrade process
Follow these steps to downgrade to an earlier version of Windows software:

Use genuine Windows media and a corresponding product key for the version of Windows that is eligible for downgrade. The media/key should come from a previously licensed product from the OEM or retail channel.
End users who are licensed separately through Microsoft Volume Licensing (VL) may provide their VL media and key to a system builder to facilitate the downgrade on their own systems.
Insert the downgrade-eligible version of Windows media and follow the installation instructions.
Enter the product key.
If the software was previously activated, it cannot be activated online. In this case, the appropriate local Activation Support phone number will be displayed. Call the number and explain the circumstances. When it is determined that the end user has an eligible Windows license, the customer service representative will provide a single-use activation code to activate the software. Please note that Microsoft does not provide a full product key in this scenario.
Activate the software.
 
Hmm... After reading this, I think I'll stick to Windows 7 for a while longer. I know they're phasing it out a little with mainstream updates ending next year and full support ending in 2020 but I will try to stay with the more familiar 7 for as long as possible.

Still, I feel sure that they will have worked the bugs out of Windows 8 either by now OR they will within the next few years. That said, I can certainly understand why Enthusiasts fight the change over like the plague as we all like to stay with what we know.
 
I'm going to continue to be happy holding on to my Win 7 license for a long time to come :)

Actually gamers and enthusiasts were the people who jumped onto Win8 first! Many people just went back to Win7. I've tried both and my main rig is happy on Win7. Performance wise there's not much to talk about but some parts of Win8 I like and some really bug me.

Yea, Win8 did have a few issues to start with. like a confusing interface and it wasn't the easiest to shut down either. :| My mom has it on her laptop and I could figure out just WHERE the shutdown switch was. Thankfully, they fixed that in one of the updates for it.

I may give it a try some day to see how well it looks and feels since we know performance wise that they're the same.
 
From what i remember i did have quite noticable performance increase going from windows 7 to windows 8.1 on a low end apu (amd a6 -6400k)

I'm considering a HTPC build with an APU, if that materializes I'll consider rerunning the tests. But at present, with Intel it makes no difference.
