Benchmarking a Windows 10 Home Laptop
As you may recall from my article on buying this so-called new laptop, I have an Acer laptop that’s cheap, heavy and running an i3 processor with 4GB RAM and (mostly) Windows 10 Home. I have replaced the slow HDD with a fast SSD Samsung 850 EVO drive.
As I helped a friend with some computer issues, I noticed that she had a very similar (but lighter) laptop (also Acer with 4GB RAM and same OS) with a less powerful N3060 processor. I was curious to see how the two computers performed in comparison, so I asked her to run some benchmarking software while using it and I did the same.
The quickest way to measure the performance of a Windows laptop is probably the “Windows Experience Index” which used to be made available in the “system” window, which one can bring up in several ways, such as pressing the Windows key + Pause/Break.
That is no longer shown in Windows 10, but it can be found by typing “winsat formal -v -xml c:\winstatresults.xml” in an admin command prompt. In my case, it ran for less than 2 minutes with a 4.4 system score.
To my knowledge, the free benchmarking suites for Windows computers include Novabench, Prime 95, PCMark, 3DMark, SiSoft Sandra. I skipped PCMark and 3DMark as, at 2GB and, respectively, 4GB, they are far too hefty for what I need and decided to go with Prime95 as that seemed to be the only one that is also portable.

I chose this one for the comparison as it seemed like a small download (from mersenne.org) and it was portable. However, the software belongs to a “prime search” project and their aim is to use your CPU cycles in a distributed model to search for such numbers. There is no bitcoin mining malware as far as I can tell – you have to press “Just Stress Testing” in the first window, then cancel the Torture Test offer and finally choose Benchmark under the Options menu.
Her results seem to indicate her laptoptablet being 4-5 times slower than mine. Her computer also had a McAfee antivirus as well as other Acer bloatware. I started to uninstall McAfee as the benchmark was running.

It is a bit difficult interpreting these numbers, but from the list of results (mersenne-results), the one closest to mine would be i3-4005U. Anyway, the numbers (mine are below) do indeed match the subjective observations, as her computer seemed extremely slow.
In contrast, my own laptop had a significantly better processor (though obsolete by today’s standards), no McAfee and a more or less clean Windows 10 install. Mine is updated, with the “creators update” blocked. However, the computer was in use while the benchmark was running with a Chrome-based browser with about 10 extensions and with two windows having a total of about 20 tabs, VLC playing a SomaFM radio stream, and most software running off a Veracrypt-ed drive; also f.lux.

Quitting GIMPS after current work completes.
A comparison between the i3 and Pentium (e.g., gadgets-compare) is rather subjective, as often the exact version compared might not match what one has, as it happens to these newer ones.
On Quora, somebody compares the newer i3-7100 and the G4620 (quora-comp).
At this moment (December 2017) I’m not sure there really is much difference. The Pentium G4620 is based on the Kaby Lake architecture, just like the 7-series i3s. Just like the 7-series i3s the Pentium has Hyper Threading and two processing cores for four threads. They both have intel 630 integrated graphics and both use identical 1151 sockets. In fact the only real difference between the two is that the i3 supports AVX2.0 while the Pentium has no AVX support and the Pentium has a lower core clock.
As a point of interest UserBenchmark places the performance of the i3–7100 as about 4–5% greater than the Pentium G4620:
Intel Core i3-7100 vs Pentium G4620
Interestingly, the i3–7100 clock is 3.9ghz, which is about 5% faster than the G4620’s 3.7ghz core clock. So the Pentium’s performance is directly inline with what you’d expect of the same generation i3 with the same clock rate.
It’s my belief that the current crop of Pentium processors are simply i3s that failed to test well enough after manufacture for the i3 brand. Thus they’re sold for a lower price with some features turned off and a lower clock rate. This is a fairly standard practice in CPU marketing and development.

The help section explains the numbers and to me it doesn’t seem very rigorous if you want to use it for comparison benchmarking.
There are two tests:
- Compression with LZMA method
- Decompression with LZMA method
The benchmark shows a rating in MIPS (million instructions per second). The rating value is calculated from the measured speed, and it is normalized with results of Intel Core 2 CPU with multi-threading option switched off. So if you have modern CPU from Intel or AMD, rating values in single-thread mode must be close to real CPU frequency.
You can change the dictionary size to increase memory usage. Also you can change the number of threads.
The CPU Usage column shows the percentage of time the processor is working. It's normalized for a one-thread load. For example, 180% CPU Usage for 2 threads can mean that average CPU usage is about 90% for each thread.
The Rating / Usage column shows rating normalized for 100% of CPU usage. That column shows performance of the one CPU thread. It must be close to real CPU frequency, if you have modern CPU.
The Total rating shows averages of the compressing and decompression ratings.
Compression speed and rating strongly depend from memory (RAM) latency.
Decompression speed and rating strongly depend on CPU integer operations. For example, an Intel Pentium 4 has big branch misprediction penalty (which is effect of long pipeline) and pretty slow multiply and shift operations. So, the Pentium 4 has pretty low decompressing ratings.
sandra
Sisoftware Sandra is a slightly more complex testing suite, using a client-server model, which makes it better suited for LANs.
I found the stand-alone install difficult to use and a bit buggy but it identified and reported on the hardware well.

I uninstalled it and it offered a license in return for completing some tasks – these involved depositing money with a betting site and buying fast food gift cards, so I passed.
Most buying advice no longer considers i3 processors, recommending an Atom or N#### class processor for budget conscious buyers, and i5-i7 for the rest (lptp-cpu).
In conclusion, I recommend Novabench as the only free benchmarking software worth trying. If, like me, you are using an encrypted drive, you might want to install it on the main (unencrypted) drive, so that you can test without the encryption software running.
