Lenovo IdeaPad U400 Notebook Review


SiSoftware Sandra and Cinebench Performance

Preliminary Testing with SiSoft SANDRA 2011
Synthetic Benchmarks

We started off our testing with SiSoftware's SANDRA 2011, the System ANalyzer, Diagnostic and Reporting Assistant.  We ran four of the built-in subsystem tests (CPU Arithmetic, Memory Bandwidth, Physical Disks).
All of the scores reported below were taken with the processor running at its default clock speeds of 2.4GHz with 6GB of DDR3 RAM running in dual-channel mode.


Processor Arithmetic


Multi-Media


Memory Bandwidth

SiSoft Sandra didn't reveal anything surprising; the U400 posted strong scores in all categories.

Cinebench R11.5 64bit
Content Creation Performance

Maxon's Cinebench R11.5 benchmark is based on Maxon's Cinema 4D software used for 3D content creation chores and tests both the CPU and GPU in separate benchmark runs. On the CPU side, Cinebench renders a photorealistic 3D scene by tapping into up to 64 processing threads (CPU) to process more than 300,000 total polygons, while the GPU benchmark measures graphics performance by manipulating nearly 1 million polygons and huge amounts of textures.

 

Here's where we start to see some chinks in the armor. While the innards are impressive for medium-duty gaming, multimedia and conventional chores, it's clear that the U400 isn't cut out for heavy duty computational work. Or, it can cut it, but it'll cut far slower than workstation type notebooks. But you knew that.
