Acer Aspire S7-393 Review (2015): Refreshed With Intel's Broadwell

LAME MT and Cinebench

In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular 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.

Lame MT Benchmark
Audio Transcoding on the CPU
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 S7-393 came within one second of the top time for lightweight laptops on its multi-threaded test.  Better yet, its time of 33 seconds was the best of any laptop on our chart for single-threaded performance.  It's also, not coincidentally, the only laptop running an i7-5500U processor on the chart.

Cinebench R11.5
3D Rending On The CPU And Integated 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 Aspire S7-393 beat a number of its peers on Cinebench for both its OpenGL and CPU tests.  It was stronger on OpenGL than CPU, coming in at just around eight percent or so of our benchmark leader for lightweight laptops.  Its CPU performance was a little less impressive given how well its peers performed—even Haswell systems did a bit better than Acer's Broadwell-based laptop.
