Har Windows 10 Mobile en chance mod Windows Phone 8.1 med hensyn til ydeevne?

Windows 10 Mobile er netop blevet lanceret uden for meget fanfare fra Microsofts^(Microsoft) side, og mange brugere har startet opgraderingsprocessen fra Windows Phone 8.1 . Denne opgradering betyder dog ikke kun et nyt udseende og nye og spændende funktioner. Desværre vil det også betyde et par fejl og ydeevneproblemer. Vi tog to smartphones med meget forskellig hardware, installerede begge operativsystemer på dem og sammenlignede derefter ydeevnen fra hvert operativsystem ved hjælp af flere tests og benchmarks. Her er, hvad vi har lært:

Windows 10 Mobile vs. Windows Phone 8.1 - Præstationssammenligningen

Vi er to kolleger, der har arbejdet på denne sammenligning sideløbende. En af os havde en Nokia Lumia 930 med Windows Phone 8.1 , og den anden havde en Microsoft Lumia 640 med Windows Phone 8.1 . Disse to smartphones er meget repræsentative for Windows Phone -økosystemet, både hvad angår funktioner og popularitet. Lumia 930 er den mest kraftfulde smartphone med Windows Phone 8.1 , mens Lumia 640 er en af de mest overkommelige og populære Windows Phone -enheder. Vi er begge baseret i Rumænien^(Romania), i forskellige byer, og vi bruger forskellige mobiludbydere. Vi kørte begge de samme tests, i samme rækkefølge, før og efter opgraderingen til Windows 10 Mobile^{(making the upgrade to Windows 10 Mobile)} .

Din smartphones opstartstid - Vinder: Windows Phone 8.1

Som du kan se, i skemaet nedenfor, tilføjer Windows 10 Mobile ret meget til din smartphones opstartstid. Microsoft Lumia 640 startede 28 % langsommere, da Windows 10 Mobile blev installeret, mens Lumia 930 var 33 % langsommere under opstartsproceduren.

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Indvirkningen Windows 10 Mobile har på din smartphones opstartstid er meget stor sammenlignet med Windows Phone 8.1.^{(The impact Windows 10 Mobile has on your smartphone's startup time is very large when compared to Windows Phone 8.1.)}

Webbrowsinghastighed - Vinder: Ingen

Mange mennesker surfer på nettet på deres smartphones dagligt. Det er derfor, vi anså det for vigtigt at køre et benchmark for hurtig webbrowsing: SunSpider . Som du kan se nedenfor, var Windows 10 Mobile lidt langsommere på Lumia 930 (med 6%) og lidt hurtigere på Lumia 640 (med 2%).

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Disse resultater tillader os ikke at drage en klar konklusion. Når det kommer til internetbrowsinghastigheden ^{(When it comes to the web browsing)} , ^(speed) bør din oplevelse være ens på begge operativsystemer. ^{(, your experience should be similar on both operating systems.)}Men webbrowserne er forskellige i Windows Phone 8.1 og Windows 10 Mobile , og de tilbyder forskellige funktioner. Det er meget sandsynligt, at du vil sætte mere pris på Microsoft Edge fra Windows 10 Mobile end Internet Explorer fra Windows Phone 8.1 .

Hastigheden på din dataforbindelse - Vinder: Windows 10 Mobile

De to smartphones, vi har brugt til at sammenligne Windows 10 Mobile med Windows Phone 8.1 , arbejdede hos forskellige teleudbydere fra forskellige geografiske placeringer. På Lumia 640 havde vi en god 4G-dataforbindelse, mens vi på Lumia 930 kun havde en 3G-dataforbindelse. Vi brugte SpeedTest til at se, hvilket operativsystem der er i stand til at levere hurtigere downloads og uploads på internettet^(Internet) .

Når man måler downloadhastigheden, er der ingen klar vinder. De forskelle, vi har bemærket, er små nok til ikke at blive bemærket under regelmæssig brug.

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Ved måling af uploadhastigheden på internettet lykkedes det Windows 10 Mobile at være hurtigere end Windows Phone 8.1^{(When measuring the upload speed on the Internet, Windows 10 Mobile managed to be faster than Windows Phone 8.1)} på både smartphones og mobilforbindelser.

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Dernæst ønskede vi at måle den ydeevne, de to operativsystemer tilbyder, når de kører apps, skriver data ind i RAM -hukommelsen eller lagerpladsen, hvor effektivt de brugte grafikchipsene på de to smartphones, og så videre. For at gøre det kørte vi flere benchmarks.

WP Bench -benchmark - Vinder: Windows Phone 8.1

Vi startede med at køre WP Bench- benchmark på begge smartphones. Den tester hastigheden på processoren, grafikchippen, hukommelsen og lageret på din smartphone. Lad^(First) os først se på resultatet opnået i CPU- testene. I disse test er det vigtigt at opnå en lavere score. Jo lavere score, jo hurtigere er operativsystemet i at arbejde med smartphonens processor.

På Lumia 640 var Windows 10 Mobile 9 % langsommere end Windows Phone 8.1 , mens den på Lumia 930 var 3 % langsommere.

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Det ser ud til, at Windows 10 Mobile på lavere enheder med mindre kraftfulde processorer er langsommere end Windows Phone 8.1 , når de arbejder med CPU'en^(CPU) . På avancerede enheder med kraftigere processorer er forskellen ikke meningsfuld nok til at kunne mærkes ved normal brug.

Derefter så vi på resultaterne opnået i de andre test, der tilbydes af WP Bench : hukommelse, lagring og grafik. Vi kiggede også på den generelle score målt af WP Bench , så vi kan sammenligne ydeevnen fra de to operativsystemer.

Som du kan se nedenfor, var Windows 10 Mobile på ^(Mobile)Lumia 640 6 % langsommere end Windows Phone 8.1 .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

På Lumia 930 var Windows 10 Mobile igen 6 % langsommere end Windows Phone 8.1 .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Ifølge WP Bench- benchmark er the performance offered by Windows 10 Mobile is 6% lower than that of Windows Phone 8.1 på den samme smartphone.

Multibench 2 benchmark - Vinder: Windows Phone 8.1

Multibench 2^{(Multibench 2)} benchmark evaluerer hastigheden på din smartphones processor, dataoverførsler, hukommelsesoverførsler og grafikchippens. På Lumia 640 er situationen som følger:

Windows 10 Mobile var 3 % hurtigere end Windows Phone 8.1 i processortesten. Dette er i konflikt med resultaterne opnået i WP Bench CPU- testene og bekræfter de resultater, vi har set i SunSpider . Den eneste rimelige konklusion at drage er, at der højst sandsynligt ikke er nogen hastighedsgevinst ved at arbejde med CPU'en^(CPU) , når du bruger Windows 10 Mobile versus Windows Phone 8.1 .
Windows Phone 8.1 var 16 % hurtigere end Windows 10 Mobile med at overføre data til og fra lagerpladsen.
Windows Phone 8.1 var 10 % hurtigere end Windows 10 Mobile i hukommelsestesten.
Windows Phone 8.1 var 396 % hurtigere end Windows 10 Mobile i grafiktesten. Dette resultat lyder for godt til at være sandt, og den måde, Multibench 2^{(Multibench 2)} beregner sine resultater på i Windows 10 Mobile , skal sandsynligvis opdateres, så den returnerer mere realistiske resultater i Windows 10 Mobile .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

På Lumia 930 er situationen som følger:

Windows 10 Mobile var 2 % hurtigere end Windows Phone 8.1 i processortesten.
Windows Phone 8.1 var 20 % hurtigere i dataoverførselstesten.
Windows Phone 8.1 var 6 % hurtigere i hukommelsestesten.
Windows Phone 8.1 var 362 % hurtigere i grafiktesten. Igen^(Again) er dette højst sandsynligt en regnefejl i Multibench 2 , og benchmark skal opdateres, så det bedre afspejler den sande ydeevne af grafikchippen i Windows 10 Mobile .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Multibench 2 har en tendens til at bekræfte nogle af resultaterne opnået med WP Bench -benchmark, som siger, at Windows Phone 8.1 er mere effektiv til at bruge din smartphones hardware til at levere den ydeevne, du har brug for^{(Windows Phone 8.1 is more efficient in using your smartphone's hardware to deliver the performance you need)} .

AnTuTu benchmark - Vinder: Windows Phone 8.1

AnTuTu er et andet benchmark, der evaluerer mange ting, herunder: hukommelsen, processoren, 2D-grafikken, hastigheden på lagerpladsen og så videre. Det adskiller sine data i masser af komplicerede subscores, som er svære at følge, men det giver også en generel score, som vi brugte til sammenligning.

Som du kan se nedenfor, på Lumia 640 var Windows 10 Mobile 7 % langsommere end Windows Phone 8.1 , mens på Lumia 930 var Windows 10 Mobile 6 % langsommere end Windows Phone 8.1 .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

AnTuTu benchmark viser endnu en gang, at Windows 10 Mobile tilbyder mindre ydeevne på den samme smartphone end Windows Phone 8.1.^{(The AnTuTu benchmark shows one more time that Windows 10 Mobile offers less performance on the same smartphone than Windows Phone 8.1.)}

Batteritid - Vinder: Ingen

Vi ved, at batteritid er et vigtigt aspekt for enhver smartphonebruger. Derfor har vi kørt WP Bench batteritesten, som stresser smartphonen maksimalt, indtil den dræner hele batteriet. Som du kan se nedenfor, varede Windows Phone 8.1 på Lumia 640 ^{(Windows Phone 8.1)}3^{(Lumia 640)} minutter mere end Windows 10 Mobile , mens Windows 10 Mobile på Lumia 930 ^(Mobile)varede^{(Lumia 930)} 7 minutter mere end Windows Phone 8.1 .

Windows 10 Mobile, Windows Phone 8.1, ydeevne, sammenligning, benchmarks, målinger

Fra disse resultater er det indlysende, at der ikke er nogen vigtig forskel mellem Windows Phone 8.1 og Windows 10 Mobile, når det kommer til batterilevetid. ^{(there is no important difference between Windows Phone 8.1 and Windows 10 Mobile when it comes to battery-life.)}De to styresystemer dræner din smartphones batteri på næsten samme tid.

Konklusion: Windows Phone 8.1 er hurtigere end Windows 10 Mobile

Dette burde ikke være en overraskelse for de fleste brugere: Windows Phone 8.1 er et yderst optimeret styresystem, som gør stor brug af selv den langsomste smartphone-hardware. Windows 10 Mobile har et stykke vej foran, indtil det når samme niveau af polering og ydeevne. Til gengæld for nye funktioner og nogle tabte funktioner får du meget længere opstartstid og mindre ydeevne, især på low-end smartphones med mindre kraftfuld hardware.

Does Windows 10 Mobile stand a chance against Windows Phone 8.1 in terms of performance?

Windows 10 Mobile waѕ just launched without too much fanfare on Miсrosoft's part and manу users have started the upgrade process from Windows Phone 8.1. However, this upgrade won't mean just a new look and new and еxciting feature s. Unfortunately, it will also mean a few bugs and performance issues. We took two smartphoneѕ with very different hardware, installed both oрerating systems on them and then comparеd the рerformance offered by each operаting syѕtem, using several tests and benchmarks. Here's what we hаve learned:

Windows 10 Mobile vs. Windows Phone 8.1 - The performance comparison

We are two colleagues wh o worked on this comparison in parallel. One of us had a Nokia Lumia 930 with Windows Phone 8.1 and the other had a Microsoft Lumia 640 with Windows Phone 8.1. These two smartphones are very representative for the Windows Phone ecosystem, both in terms of features and popularity. The Lumia 930 is the most powerful smartphone with Windows Phone 8.1 while Lumia 640 is one of the most affordable and popular Windows Phone device s. We are both based in Romania, in different cities, and we use different cellular providers. We both ran the same tests, in the same order, before and after making the upgrade to Windows 10 Mobile.

Your smartphone's startup time - Winner: Windows Phone 8.1

As you can see, in the chart below, Windows 10 Mobile adds quite a lot to the startup time of your smartphone. Microsoft Lumia 640 started 28% slower when Windows 10 Mobile was installed, while Lumia 930 was 33% slower during the startup procedure.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

The impact Windows 10 Mobile has on your smartphone's startup time is very large when compared to Windows Phone 8.1.

Web browsing speed - Winner: None

Many people browse the web on their smartphones on a daily basis. That's why we considered it important to run a quick web browsing benchmark: SunSpider. As you can see below, Windows 10 Mobile was slightly slower on the Lumia 930 (by 6%) and slightly faster on the Lumia 640 (by 2%).

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

These results don't allow us to draw a clear conclusion. When it comes to the web browsing speed , your experience should be similar on both operating systems. However, the web browsers are different in Windows Phone 8.1 and Windows 10 Mobile and they offer different features. It is very likely that you will appreciate Microsoft Edge from Windows 10 Mobile more than Internet Explorer from Windows Phone 8.1.

The speed of your data connection - Winner: Windows 10 Mobile

The two smartphones we have used for comparing Windows 10 Mobile with Windows Phone 8.1, worked on different telecom providers, from different geographical locations. On the Lumia 640 we had a good 4G data connection while on the Lumia 930 we had only a 3G data connection. We used SpeedTest to see which operating system is able to deliver faster downloads and uploads on the Internet.

When measuring the download speed, there is no clear winner. The differences we have noticed are small enough not to be noticed during regular use.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

When measuring the upload speed on the Internet, Windows 10 Mobile managed to be faster than Windows Phone 8.1 on both smartphones and cellular connections.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

Next, we wanted to measure the performance offered by the two operating systems when running apps, writing data into the RAM memory or the storage space, how efficiently they used the graphics chips on the two smartphones, and so on. In order to do that, we ran several benchmarks.

WP Bench benchmark - Winner: Windows Phone 8.1

We began by running the WP Bench benchmark on both smartphones. It tests the speed of the processor, the graphics chip, the memory and the storage on your smartphone. First, let's take a look at the result obtained in the CPU tests. In these tests it is important to obtain a lower score. The lower the score, the faster is the operating system in working with the smartphone's processor.

On the Lumia 640, Windows 10 Mobile was 9% slower than Windows Phone 8.1 while on the Lumia 930, it was 3% slower.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

It seems that, on lower-end devices with less powerful processors, Windows 10 Mobile is slower than Windows Phone 8.1 when working with the CPU. On high-end devices with more powerful processors, the difference isn't meaningful enough to be felt in normal use.

Then, we looked at the results obtained in the other tests offered by WP Bench : memory, storage and graphics. We also looked at the general score measured by WP Bench , so that we can compare the performance offered by the two operating systems.

As you can see below, on the Lumia 640, Windows 10 Mobile was 6% slower than Windows Phone 8.1.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

On the Lumia 930, Windows 10 Mobile was, again, 6% slower than Windows Phone 8.1.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

According to the WP Bench benchmark, the performance offered by Windows 10 Mobile is 6% lower than that of Windows Phone 8.1 on the same smartphone.

Multibench 2 benchmark - Winner: Windows Phone 8.1

The Multibench 2 benchmark evaluates the speed of your smartphone's processor, data transfers, memory transfers and that of the graphics chip. On the Lumia 640, the situation is as follows:

Windows 10 Mobile was 3% faster than Windows Phone 8.1, in the processor test. This conflicts with the results obtained in the WP Bench CPU tests and confirms the results we have seen in SunSpider. The only fair conclusion to draw is that, most probably, there's no speed gain in working with the CPU, when using Windows 10 Mobile versus Windows Phone 8.1.
Windows Phone 8.1 was 16% faster than Windows 10 Mobile in transferring data to and from the storage space.
Windows Phone 8.1 was 10% faster than Windows 10 Mobile in the memory test.
Windows Phone 8.1 was 396% faster than Windows 10 Mobile in the graphics test. This result sounds to o good to be true and most probably, the way the Multibench 2 calculates its results in Windows 10 Mobile needs to be updated so that it returns more realistic results in Windows 10 Mobile.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

On the Lumia 930, the situation is as follows:

Windows 10 Mobile was 2% faster than Windows Phone 8.1 in the processor test.
Windows Phone 8.1 was 20% faster in the data transfer test.
Windows Phone 8.1 was 6% faster in the memory test.
Windows Phone 8.1 was 362% faster in the graphics test. Again, this is most probably a calculation error in Multibench 2 and the benchmark needs to be updated so that it better reflects the true performance of the graphics chip in Windows 10 Mobile.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

Multibench 2 tends to confirm some of the results obtained with the WP Bench benchmark, which state that Windows Phone 8.1 is more efficient in using your smartphone's hardware to deliver the performance you need.

AnTuTu benchmark - Winner: Windows Phone 8.1

AnTuTu is another benchmark that evaluates lots of things, including: the memory, the processor, the 2D graphics, the speed of the storage space and so on. It separates its data into lots of complicated subscores which are hard to follow but it also provides a general score which we used for comparison.

As you can see below, on the Lumia 640, Windows 10 Mobile was 7% slower than Windows Phone 8.1 while on the Lumia 930, Windows 10 Mobile was 6% slower than Windows Phone 8.1.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

The AnTuTu benchmark shows one more time that Windows 10 Mobile offers less performance on the same smartphone than Windows Phone 8.1.

Battery time - Winner: None

We know that battery time is an important aspect for every smartphone user. That's why we have run the WP Bench battery test which stresses the smartphone to the maximum until it drains all its battery. As you can see below, on the Lumia 640, Windows Phone 8.1 lasted 3 minutes more than Windows 10 Mobile, while on the Lumia 930, Windows 10 Mobile lasted 7 minutes more than Windows Phone 8.1.

Windows 10 Mobile, Windows Phone 8.1, performance, comparison, benchmarks, measurements

From these results it is obvious that there is no important difference between Windows Phone 8.1 and Windows 10 Mobile when it comes to battery-life. The two operating systems drain your smartphone's battery in just about the same time.

Conclusion: Windows Phone 8.1 is faster than Windows 10 Mobile

This should not be a surprise to most users: Windows Phone 8.1 is a highly optimized operating system, which makes great use even of the slowest smartphone hardware. Windows 10 Mobile has a long way ahead until it reaches the same level of polish and performance. In return for new features and some lost features, you get a much longer startup time and less performance, especially on low-end smartphones with less powerful hardware.
