Windows Phone 8.1 benchmarks

We already said in our Windows Phone 8.1 review that the OS feels smoother than its predecessor, but is it really? Well we’ve decided to run some benchmark tests and see how the new OS performs under pressure. Microsoft has done quite a few optimizations for sure, so we are eager to see how the update is handled by different phones.

We had three Lumia phones around for our tests – Lumia 720, Lumia 1020 and Lumia 1520. We rаn each benchmark on Windows Phone 8 with GDR3 and Nokia Black updates, and then we’ve updated all three devices to the latest Windows Phone 8.1 Developer’s Preview.
The first test measures the single-core performance by calculating the Number Pi. All phones scored the same on both version of the OS, but that’s hardly surprising as it’s a strictly CPU-intensive test.

Pi Benchmark

Lower is better
  • Nokia Lumia 1520 (WP8.1) 146
  • Nokia Lumia 1520 (WP8.0) 146
  • Nokia Lumia 1020 (WP8.1) 215
  • Nokia Lumia 1020 (WP8.0) 215
  • Nokia Lumia 720 (WP8.1) 336
  • Nokia Lumia 720 (WP8.0) 336
Then we got to the compound test AnTuTu. All three Lumia phones showed no significant rise or drop in the performance. So there is nothing conclusive about any potential performance benefits of Windows Phone 8.1.

AnTuTu

Higher is better
  • Nokia Lumia 1520 (WP8.1) 25659
  • Nokia Lumia 1520 (WP8.0) 24797
  • Nokia Lumia 1020 (WP8.1) 11567
  • Nokia Lumia 1020 (WP8.0) 12064
  • Nokia Lumia 720 (WP8.1) 7135
  • Nokia Lumia 720 (WP8.0) 7319
Finally, we used the popular cross-platform BaseMark OS II compound benchmark. The three Lumia phones scored noticeably higher when running on the Windows Phone 8.1 update, testifying that the Windows Phone 8.1 OS indeed brings about a certain performance boost over its predecessor.

Basemark OS II

Higher is better
  • Nokia Lumia 1520 (WP8.1) 1116
  • Nokia Lumia 1520 (WP8.0) 1012
  • Nokia Lumia 1020 (WP8.1) 526
  • Nokia Lumia 1020 (WP8.0) 495
  • Nokia Lumia 720 (WP8.1) 332
  • Nokia Lumia 720 (WP8.0) 319
Windows Phone 8.1 comes with a brand new Internet Explorer 11 web browser that brings lots of new goodies and… performance improvements. We explain all the new stuff a bit further down, but for now we’ll just show you how the new IE11 stacks against its previous version and other competing web browsers.
SunSpider measures the JavaScript performance of the web browser. While the Internet Explorer 11 on Lumia 1520 and 1020 demonstrated boost of its JavaScript capabilities, the app on Lumia 720 somehow managed to get worse. We believe this might be fixed in the final version of the OS though.

SinSpider 1.0.2

Lower is better
  • Nokia Lumia 1520 (WP8.1) 514
  • Nokia Lumia 1520 (WP8.0) 543
  • Nokia Lumia 1020 (WP8.1) 912
  • Nokia Lumia 1020 (WP8.0) 965
  • Nokia Lumia 720 (WP8.1) 1756
  • Nokia Lumia 720 (WP8.0) 1430
BrowserMark 2 compound benchmark tests the web browsers in several departments. While Internet Explorer 11 is still behind its competitors, it is definitely better and faster than the IE10, which comes with Windows Phone 8.0.

BrowserMark 2

Higher is better
  • Nokia Lumia 1520 (WP8.1) 2699
  • Nokia Lumia 1520 (WP8.0) 2019
  • Nokia Lumia 1020 (WP8.1) 2261
  • Nokia Lumia 1020 (WP8.0) 1767
  • Nokia Lumia 720 (WP8.1) 1769
  • Nokia Lumia 720 (WP8.0) 1477
Finally, we put the phones through the standard HTML5Test and the entire gang showed similar bump in its HTML5 capabilities, courtesy of Windows Phone 8.1.

HTML 5 Test

Higher is better
  • Nokia Lumia 1520 (WP8.1) 372
  • Nokia Lumia 1520 (WP8.0) 328
  • Nokia Lumia 1020 (WP8.1) 368
  • Nokia Lumia 1020 (WP8.0) 328
  • Nokia Lumia 720 (WP8.1) 368
  • Nokia Lumia 720 (WP8.0) 328
So overall, the new OS brings along a definite speed improvement over Windows Phone 8. We hope to see the final version does even better in this respect.

iPhone 8 Plus and iPhone 8 now rule DxOMark's rankings with best smartphone cameras ever tested

Image
With sales of the iPhone 8 and iPhone 8 Plus starting today, DxOMark has published comprehensive reviews of both handsets' cameras. Lo and behold, they have jumped straight to the first two spots in the DxOMark rankings, leaving the HTC U11 and Google Pixel in the dust. The Pixel used to be the king of DxO until the U11 got the same score of 90. Now though, the iPhone 8 Plus' camera becomes the best that the lab has ever tested, with a score of 94. The iPhone 8's shooter isn't far behind, ranked No.2 with its 92 points. The iPhone 8 Plus shines in picture taking, with a record-breaking Photo score of 96, while for recording videos it gets a score of 89 - tied with the HTC U11 and slightly below the Pixel's 91. The iPhone 8 Plus has "outstanding image quality" and "an industry-leading Portrait mode". It is at the top of the charts in nearly every category, while its advanced software means it does "an amazing job" ...

Microsoft has laid Windows Vista to rest

Image
Today, Microsoft is “sunsetting” Windows Vista. That means it will no longer be supported with security updates from Microsoft. So if you find yourself with a machine running Windows Vista, you should look at upgrading to a newer version of Windows in order to stay secure. Windows 2000, Windows Me, Windows XP, Windows Vista In the early 2000s, Windows pumped three major consumer operating systems: In early 2000 came Windows 2000, later that year, Windows released a Windows Millenium update which was filled with glitches and bugs, including a way to bypass the password screen by hitting a few keys. Then came Microsoft’s saving grace: Windows XP. Windows XP then became a very popular operating system getting its third service pack in 2008. Back-tracking a couple of years to 2006, Windows Vista is released to the public. Windows Vista was abundant with glitches, bugs, and the overall performance of the OS was quite awful on hardware available at the time: when d...

Google confirms that it's launching two flagship Android Wear smartwatches in early 2017

Image
Two reports from a few months ago claimed that Google was working on two high-end smartwatches of its own, which were supposed to debut alongside the Android Wear 2.0 release this year. But then the new version of the company's wearable OS got delayed until 2017, and so we assumed the launch of the watches was postponed for that reason. It turns out that's exactly what happened. Today Jeff Chang, Google's product manager of Android Wear, has confirmed that the company is developing two flagship smartwatches which will be on the market in the first quarter of next year (so before March 31). These will be the first devices to launch running Android Wear 2.0, but then throughout 2017 we'll reportedly see more watches powered by the new OS version, from other partners. Some of those may even present their wearables at CES in January, while others will wait for Baselworld in March. Google's watches will not be Pixel-branded as you may have expected...

Samsung explains the new tech behind the Galaxy S5 Super AMOLED display

Image
While much fuss has been made out of the Galaxy S5 display – the company’s 1080p Super AMOLED diamond matrix having been around since the Galaxy S4, after all – it turns out that Samsung has put quite a bit of work into making its latest panel the best ever. The company has posted some interesting demos of the new capabilities baked into the Galaxy S5 display, including local contrast enhancement for bright conditions, Adapt Display tech for different lighting, and different color realization modes for display photos. Local contrast enhancement allows the display itself to analyze and segment the display under different lighting conditions, meaning that it can change both the illumination and contrast level, including the ability to dim the display even further to avoid eye strain from excessive brightness in dark conditions. Adapt Display on the S5 means that the display will automatically change according to surrounding lighting conditions, including color ran...
