Geekbench 3

Geekbench 3 is Primate Labs' cross-platform processor benchmark, with a new scoring system that separates single-core and multi-core performance, and new workloads that simulate real-world scenarios. Geekbench 3 makes it easier than ever to find out if your computer is up to speed. Every test in Geekbench 3 is multi-core aware. This allows Geekbench to show you the true potential of your system. Whether you're running Geekbench on a dual-core phone or a 32-core server, Geekbench is able to measure the performance of all the cores in your system.

Geekbench acts much like a traditional synthetic processor benchmark would, giving us an idea of the peak performance that the CPU offers in both integer and floating point math.

Geekbench starts out giving the performance advantage to the Exynos 5433 processor in the unlocked Galaxy Note 4. Single threaded performance is only slightly behind the iPhone 6 though the multi-threaded results are a large jump over the next fastest option, the Google Nexus 6. This is the only smartphone in our testing that uses the big.LITTLE 8-core CPU design, for now.

Floating point performance looks similar though the Cyclone cores of the Apple A8 have a bigger single threaded advantage over anything else we have in-house. Multi-threaded performance is also closer but the Exynos 5433 is still the best available option for a smartphone.

Google Octane

Octane 2.0 is a modern benchmark that measures a JavaScript engine’s performance by running a suite of tests representative of today’s complex and demanding web applications. Octane‘s goal is to measure the performance of JavaScript code found in large, real-world web applications, running on modern mobile and desktop browsers.

The updated Octane 2.0 benchmark includes four new tests to measure new aspects of JavaScript performance, among which: garbage collection / compiler latency and asm.js-style JavaScript performance.

Our testing with Google Octane was done exclusively on the latest version of the Chrome browser on Android, and Safari on iOS.

The Samsung Galaxy Note 4 is the fastest Android phone in our testing using Chrome for this test.

Mozilla Kraken

Kraken is a JavaScript performance benchmark created by Mozilla that measures the speed of several different test cases extracted from real-world applications and libraries. The test cases include:

  • An implementation of the A* search algorithm
  • Audio processing using Corban Brook's DSP.js library
  • Image filtering routines, including code from Jacob Seidelin's Pixastic library.
  • JSON parsing, including data from Tinderboxpushlog
  • Cryptographic routines from the Stanford JavaScript Crypto Library

Our testing with Mozilla Kraken was done exclusively on the latest version of the Chrome browser on Android and Safari on iOS.

Mozilla's JavaScript browser test is a bit older and the Exynos 5433 from Samsung has trouble keeping up with the iPhone 6 as well as the two Snapdragon 805 phones.


This is SunSpider, a JavaScript benchmark. This benchmark tests the core JavaScript language only, not the DOM or other browser APIs. It is designed to compare different versions of the same browser, and different browsers to each other.

This test mostly avoids microbenchmarks, and tries to focus on the kinds of actual problems developers solve with JavaScript today, and the problems they may want to tackle in the future as the language gets faster. This includes tests to generate a tagcloud from JSON input, a 3D raytracer, cryptography tests, code decompression, and many more examples. There are a few microbenchmarkish things, but they mostly represent real performance problems that developers have encountered.

This test is balanced between different areas of the language and different types of code. It's not all math, all string processing, or all timing simple loops. In addition to having tests in many categories, the individual tests were balanced to take similar amounts of time on currently shipping versions of popular browsers.

One of the challenges of benchmarking is knowing how much noise you have in your measurements. This benchmark runs each test multiple times and determines an error range (technically, a 95% confidence interval). In addition, in comparison mode it tells you if you have enough data to determine if the difference is statistically significant.

Our testing with SunSpider was done exclusively on the latest version of the Chrome browser on Android, and Safari on iOS.

Similar results in SunSpider - the Exynos 5433 is only able to outperform the OnePlus One using the Snapdragon 801 processor.

Vellamo 3.1

Vellamo 3.1 is designed to be an accurate, easy-to-use suite of system-level benchmarks for devices based on Android 4.0 forward. In Vellamo we want to enable performance enthusiasts to really understand their system, and how it compares to other systems, and our mission has just begun.

Vellamo began as a mobile web benchmarking tool that today has expanded to include three primary Chapters. The Browser Chapter evaluates mobile web browser performance, the Multicore Chapter measures the synergy of multiple CPU cores, and the Metal Chapter measures the single core CPU subsystem performance of mobile processors.

This test is Android-only, so the Apple results will be ignored.

Another browser test shows that the Exynos 5433, with the glory of 8-cores, isn't enough to overtake the Snapdragon 805.

Obviously where this SoC excels is in the multi-threaded testing, where the 4+4 design Samsung has chosen to implement can thrive.

The Metal test measures raw single threaded performance and the Exynos 5433 SoC is able to maintain a performance lead over the three other tested Android phones.


WebXPRT 2013 uses scenarios created to mirror the tasks you do every day to compare the performance of almost any Web-enabled device. It contains four HTML5- and JavaScript-based workloads: Photo Effects, Face Detect, Stocks Dashboard, and Offline Notes.

The Samsung Galaxy Note 4 finds itself in the middle of the pack, resulting in an overall score that is just behind the Motorola Droid Turbo and the iPhone 6. The Note 4 scores are photo effects and face detection show an impressive performance victory as it was able to outpace the Nexus 6 and the iPhone 6.

  • Allows device vendors to assess performance, drive competitive analysis, and accomplish stability testing
  • Empowers end-users to validate and compare capabilities of their phones or tablets
  • Compare your benchmark results with other uploaded results at our website - www.eembc.org/andebenchpro.php
  • Automated statistical analysis for minimum, median, and maximum values

Focuses on the key metrics that reflect the most common usage models of Android devices

  • Hardware tests exercise CPU, GPU, memory, and storage
  • Platform tests target common application services including GUI rendering, XML parsing, image operations, cryptography

The Galaxy Note 4 takes over our last CPU benchmark with a win, especially in the CoreMark test that focuses on synthetic peak performance capability. Memory bandwidth also measures high, matching that of the Nexus 6 and significantly faster than the Droid Turbo.
