Lenovo ThinkPad Edge E420s Laptop Review
SiSoft Sandra & CineBench

We continued 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).

We've started to see some notebooks ship with 8GB of memory, and while our E420s came configured with half that much, it still performed well in synthetic testing due to its high frequency (DDR3-1333). And of course here again the Sandy Bridge processor was able to show what all the fuss is about. In the Physical Disks test, the E420s returned a score comparable to other machines that use a mechanical hard drive spinning at 7200RPM.

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.
Pretty ugly, right? It always is, not because the machines we review are weak, but because Cinebench is specifically tuned for high-power workstations destined for CAD work and other professional activities. You're just not going to get far in your career if you're relying on integrated graphics to mold complex 3D models.
