iPhone 8 is world's fastest phone (it's not even close)

Sun, 24 Sep 2017 00:09:56 GMT

The "Bionic" part in the name of Apple's A11 Bionic chip isn't just marketing speak. It's the most powerful processor ever put in a mobile phone. We've put this chip to the test in both synthetic benchmarks and some real-world speed trials, and it obliterates every Android phone we tested. As far as SoCs go, Apple is incredibly far ahead of Qualcomm and Samsung. These companies have some serious soul-searching to do. I can't wait for AnandTech to dive into the A11 Bionic, so we can get some more details than just people comparing GeekBench scores.



Intel Core i9-7900X review

Tue, 04 Jul 2017 21:06:57 GMT

Intel's latest 10-core, high-end desktop (HEDT) chip - the Core i9-7900X - costs £900/$1000. That's £500/$500 less than its predecessor, the i7-6950X. In previous years, such cost-cutting would have been regarded as generous. You might, at a stretch, even call it good value. But that was at a time when Intel's monopoly on the CPU market was as its strongest, before a resurgent AMD lay waste to the idea that a chip with more than four cores be reserved for those with the fattest wallets. [...] AMD's Ryzen is far from perfect. But when you can buy eight cores that serve even the heaviest of multitaskers and content creators for well under half the price of an Intel HEDT chip, i9 and X299 are a hard sell (except, perhaps, to fussy gamers that demand a no-compromises system). The question is: Are you willing to pay a premium for the best performing silicon on the market? Or is Ryzen, gaming foibles and all, good enough? I've said this countless times, but I want to keep bringing this one home: this is what competition does. It lowers prices, improves performance, and makes Intel looks like a stumbling fool. And what better day to celebrate the benefits of competition than today? Cheers, America. Party safe!



Google Now vs. Siri vs. Cortana

Thu, 09 Oct 2014 09:33:15 GMT

So there you have it. As of October 4, Google Now has a clear lead in terms of the sheer volume of queries addressed, and more complete accuracy with its queries than either Siri or Cortana. All three parties will keep investing in this type of technology, but the cold hard facts are that Google is progressing the fastest on all fronts. Not surprising, really, considering Google's huge information lead. Still, I have yet to find much use for these personal assistants - I essentially only use Google Now to set alarms and do simple Google queries, but even then only the English ones that do not contain complicated names.



The state of cheating in Android benchmarks

Thu, 03 Oct 2013 16:07:48 GMT

With the exception of Apple and Motorola, literally every single OEM we've worked with ships (or has shipped) at least one device that runs this silly CPU optimization. It's possible that older Motorola devices might've done the same thing, but none of the newer devices we have on hand exhibited the behavior. It's a systemic problem that seems to have surfaced over the last two years, and one that extends far beyond Samsung. Pathetic, but this has been going on in the wider industry for as long as I can remember - graphics chip makers come to mind, for instance. Still, this is clearly scumbag behaviour designed to mislead consumers. On the other hand, if you buy a phone based on silly artificial benchmark scores, you deserve to be cheated.



Real world comparison: GC vs. manual memory management

Thu, 06 Sep 2012 21:32:49 GMT

"During the 4th Semester of my studies I wrote a small 3d spaceship deathmatch shooter with the D-Programming language. It was created within 3 Months time and allows multiple players to play deathmatch over local area network. All of the code was written with a garbage collector in mind and made wide usage of the D standard library phobos. After the project was finished I noticed how much time is spend every frame for garbage collection, so I decided to create a version of the game which does not use a GC, to improve performance."



Web Browser Grand Prix VI: Chrome 13, Firefox 6, Mac OS X Lion

Mon, 29 Aug 2011 14:58:05 GMT

The latest browser benchmarks are in... again - seems like there's a new one every week. This is one of the best "browser battle" articles though. Chrome 13, Firefox 6, IE9, Opera 11.50, and Safari 5.1 are put through 40-something tests on both Windows 7 and Mac OS X Lion. As a PC guy I was pretty impressed with the performance of Safari on OS X, and the reader feature looks awesome too. The author also uncovered a nasty Catalyst bug that makes IE9 render pages improperly and freeze up under heavy loads of tabs. The tables at the end pinpoint the strengths and weaknesses of each browser, which is nicer than a 1-10 or star rating. Good article, and thorough.



Test Driving GNU Hurd, with Benchmarks Against Linux

Thu, 21 Jul 2011 14:08:12 GMT

Phoronix has conducted some preliminary benchmarks, comparing Debian GNU/Hurd to Debian GNU/Linux. "There was only a handful of tests that could be successfully run under Debian GNU/Hurd and in those results the numbers were generally close, though Debian GNU/Linux was running about 4% faster in some and with the MP3 encoding the Linux OS was nearly 20% faster. Debian GNU/Hurd is an interesting project but for now its support is still in shambles, the hardware support is vastly outdated, and there is also no SMP support at this time. Regardless, it will be interesting to see how Debian GNU/Hurd turns out for the 7.0 Wheezy milestone."



C++ Clear Winner in Google Language Benchmark

Fri, 10 Jun 2011 22:22:26 GMT

"Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."



GCC 4.6, LLVM/Clang 2.9, DragonEgg Benchmarks

Tue, 29 Mar 2011 23:53:58 GMT

"Version 4.6 of GCC was released over the weekend with a multitude of improvements and version 2.9 of the Low-Level Virtual Machine is due out in early April with its share of improvements. How though do these two leading open-source compilers compare? In this article we are providing benchmarks of GCC 4.5.2, GCC 4.6.0, DragonEgg with LLVM 2.9, and Clang with LLVM 2.9 across five distinct AMD/Intel systems to see how the compiler performance compares."



WebM, H264, Theora Encoder Benchmarks

Wed, 23 Mar 2011 23:14:27 GMT

A new set of x264 and vpxenc encoder benchmarks have been published. The new benchmarks address many of the concerns raised in the comments about the methodology used in the previous article, such as using SSIM for quality measurement. Theora is also included in these tests.



WebM, H264: Encoder Speed Benchmark

Tue, 15 Mar 2011 23:32:20 GMT

A comment on the recent article about the Bali release of Googles WebM tools (libvpx) claimed that one of the biggest problems facing the adoption of WebM video was the slow speed of the encoder as compared to x264. This article sets out to benchmark the encoder against x264 to see if this is indeed true and if so, how significant the speed difference really is.



Compiler Benchmarks of GCC, LLVM-GCC, DragonEgg, Clang

Mon, 08 Nov 2010 22:43:29 GMT

"LLVM 2.8 was released last month with the Clang compiler having feature-complete C++ support, enhancements to the DragonEgg GCC plug-in, a near feature-complete alternative to libstdc++, a drop-in system assembler, ARM code-generation improvements, and many other changes. With there being great interest in the Low-Level Virtual Machine, we have conducted a large LLVM-focused compiler comparison at Phoronix of GCC with versions 4.2.1 through 4.6-20101030, GCC 4.5.1 using the DragonEgg 2.8 plug-in, LLVM-GCC with LLVM 2.8 and GCC 4.2, and lastly with Clang on LLVM 2.8."



Workstation Benchmarks: Windows 7 vs. Ubuntu Linux

Tue, 03 Aug 2010 17:20:40 GMT

Here is the continuation of a series of comparison tests that is without doubt bound to cause a huge amount of controversy: Workstation Benchmarks: Windows 7 vs. Ubuntu Linux There are performance wins and losses on both sides of the fence, but Ubuntu compares very well with Windows 7, and no doubt these tests indicate a much closer performance comparison than most people would have expected.



Phoronix Benchmarking.. Statistically Significant?

Mon, 26 Jul 2010 00:36:19 GMT

Blogger Kevin Bowling takes a look at the never-ending stream of benchmarks from Phoronix, with various Linux distros pitted against each other and even different operating systems, and he wonders, are they bullshit? . Case in point, this Debian vs FreeBSD benchmark that was submitted to OSNews yesterday.



First Look: VP8 vs. H264

Sun, 23 May 2010 09:41:47 GMT

Now that Google has opened up VP8, the big question is obviously how it'll hold up to H264. Of course, VP8 already wins by default because it's open source and royalty free, but that doesn't mean we should neglect the quality issue. Jan Ozer from StreamingMedia.com has put up an article comparing the two codecs, and concludes that the differences are negligible - in fact, only in some high-motion videos did H264 win out. As always, this is just one comparison and most certainly anything but conclusive. Update: Another comparison. I can't spot the difference, but then again, I'm no expert.
