The super benchmark: WinRAR 5.31 VS 7-Zip 16.02


Hello! I am back with another amazing article.. wait.. it is a comparison. A first on earth like the previous time. So, before I start showing you the details, let me give a self-link to my previous comparison between these two titans of the compression world:

winrar vs 7zip benchmark

 

WinRAR has had many improvements since its 5.20 version, mostly being graphical fixes and archive bits-and-pieces feature fixes.

Interestingly, 7-Zip 16.02 has had a major feature addition since the 9.34 alpha: multivolume ZIP and RAR5 extraction support. Other fixes are hardly noticeable to be honest. And this is a stable version (yay!).

My comprehensive benchmark results will be shown. But before that, few more things I want to tell you all.

One, the best archiver on the basis of feature set, supported by SqueezeChart 2014 and my own benchmark was concluded by me for major OSes in this article:

Two, WinRAR with 512 MB dictionary size usage requires only 3 GB RAM. But 7-Zip requires 11 GB RAM for 512 MB dictionary size, which is not common in PCs or laptops. So WinRAR is better for common PCs.

My benchmark is here, below this line.

System Specs

Windows 7 Home Premium (OS also makes some difference in terms of optimisation of system resources)

Core i3-2120 3.3 GHz

4 GB DDR3 RAM

1 GB AMD Radeon HD 6450 gfx card

Seagate 1 TB HDD @ 7200 rpm

Software used

WinRAR 5.31

7-Zip 16.02

PeaZip 6.02 (for the only GZip result)

Datasets

MVSC (contains Cadillacs n Dinosaurs, Marvel Superheroes VS Street Fighter,

Marvel VS Capcom, Street Fighter Alpha 2, X-Men VS Street Fighter ROMs

and Final Burn Alpha 0.2.97.05 emulator) 119 MB

NFS MW — NFS Most Wanted installed game folder 2.83 GB

Oni — Bungie’s Oni installed game folder 1.01 GB

DBZ BT3 — Dragon Ball Z Budokai Tenkaichi 3 PS2 ISO ROM 2.81 GB

Format Dict size used

RAR5 128 MB

RAR 4 MB

7Z 64 MB (Best)

7Z 32 MB (Max)

7Z 16 MB (Normal)

7Z 1 MB (Fast)

Throughout, for 7Z, LZMA2 algorithm was used.

In each case Solid compression was used.

Note: In RAR and RAR5, Best and good were almost equivalent in size and time and

hardly made difference in memory usage,

which was doubling time to benchmark so to avoid time wastage, “good” was excluded.

Note: no test was done twice, as others say to remove HDD bottleneck.

This is a real-world performance test, and as expected, no one would compress a file

twice to ensure removal of bottlenecks as it will take nearly double the time to do such a task practically.

NOTE: NO OTHER PROCESS WAS RUNNING WHILE COMPRESSING WAS GOING ON.

Time is in seconds throughout.

Conclusion

So, the best setting as I can observe is “RAR5 Fast (Solid)”. It means the newer RAR5 format used with Fast compression setting and “Solid archiving” option checked.

For even quicker compression, I will simply go with “RAR5 Fastest (Non-Solid)”.

Why have I written “Non-Solid”? Even though I used “Solid” setting, non-solid is faster than solid compression as headers for all seperate files are compressed together rather than individually treated so. But compressing these headers makes an archive much smaller at the expense of nearly 1 sec per 700 individual files. It also means the solid setting will not let you extract a file individually out of a solid archive. All files are processed and skipped except for those file(s).

WinRAR is better for daily life usage, even though 7-Zip has better compression (2-3%). But time is money, and 7-Zip wastes that to get smaller archives. WinRAR is efficient enough for daily life usage.

NOTE: FreeARC and NanoZip, the more efficient archivers than WinRAR are projects that have been abandoned.

There is a little chit-chat about FreeARC Next at encode.ru, but no progress. Moreover, Bulat Ziganshin has posted some code at GitHub, but is unwilling to release some parts as open source. There has been no update since March 2015.

As for NanoZip, there are no updates since April 30, 2014 (website updation only) and there is absolutely no source code available even though it is still in experimental stage. Suffice to say, it looks abandoned to me in 2016.

Let’s see what my readers want to say. 🙂
