Dell Latitude E7440 Touch Business Ultrabook Review

Cinebench and SiSoft SANDRA

In order to get a feel for how the Latitude E7440 compares to other ultrabooks on the market, we ran a few established benchmarks. We began our benchmark testing with Cinebench and SiSoft SANDRA.

Cinebench R11.5 64-bit
Content Creation Performance

Cinebench R11.5 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 pure computational throughput.



Although the Latitude E7440’s CPU score in Cinebench is tops, that OpenGL score is relatively weak. The primary cause is the single 4GB DIMM; 4GB is a sufficient amount of RAM, but with a lone DIMM, it runs as single channel which really kicks certain performance aspects in the teeth. Why Dell (and Lenovo, which did the same thing with the ThinkPad T440s) didn’t spend a few extra bucks to put another stick of RAM in there is a mystery.

SiSoft SANDRA 2013
Synthetic General Performance Metrics
 
We continued our testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests (CPU Arithmetic, Multimedia, Memory Bandwidth, File System).

  

  

All of the Latitude E7440’s SANDRA scores landed about where we expected them. The storage score is nice and high thanks to the SSD inside, and the Memory Bandwidth score is somewhat weak at 10.07GB/s--again, because of the lone 4GB stick of RAM.
