Lame MT and Cinebench
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which mimics a scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content. LAME is an open-source MP3 audio encoder that is used widely in a multitude of third party applications.
For this test, we created our own 223MB WAV file (a mile-long Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application, in both single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.
We've got a new champ! The Inspiron 13 7000 Special Edition eked out a small victory over the Asus T300 Chi and Surface Pro 3, and it handily bested the top machines from a year ago. Sure, it's just a few seconds here and there, but over the course of a machine's useful life, those seconds add up to differences in productivity.
3D Rending On The CPU And Integrated GPU
Cinebench R15 is a 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation suite used by animation houses and producers like Sony Animation and many others. It's very demanding of processor resources and is an excellent gauge of computational throughput. This is a multi-threaded, multi-processor aware benchmark that renders a photorealistic 3D scene (from the viral "No Keyframes" animation by AixSponza). This scene makes use of various algorithms to stress all available processor cores. The rate at which each test system was able to render the entire scene is represented in the graph below.
The Inspiron 13 7000 SE topped the charts yet again in the Cinebench test. What's notable here is that it actually secured a better score than Dell's XPS 13, which is a bona fide workhorse. Consider that the unit we're testing here is a 2-in-1 tablet, and it's all the more impressive.
