Acer Aspire R 13 Convertible 2-in-1 Review
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.
The Aspire R 13 flies through this test and earns the top spot in our chart in both the single- and multi-threaded components of the test.
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 Aspire R 13 performs very well in both components of the Cinebench test. The machine earns the top spot in the OpenGL component of the Cinebench test. In the CPU benchmark component, the 2015 Dell XPS 13 sneaks ahead of the Aspire R 13 with a score that’s 0.01 higher.
