The processor

SuperPi

SuperPi calculates the number Pi with 1 million decimals. The result is a time in seconds, so the lower is better. The time taken can be directly compared with other devices that have run the same test.

The processor does well and crunches the numbers quickly. It is slightly faster than the Acer model, so no complaints here. Both are based on the CULV platform mentioned before, which is one of the reasons why the Acer was chosen as a basis for comparison.

SiSoft Sandra CPU Arithmetic

SiSoft Sandra's Whetstone and Drystone benchmarks test the processor’s ability to perform pure number crunching that occurs during gaming or photo editing. Measures are in Mflops (Millionsof Floating Point Operations Per Second). A higher value is better.

The Acer did not go through this benchmark, and it can probably count itself lucky for that. Lenovo deliver a very good result and I am sure they would have beaten Acer.

SiSoft Sandra CPU Multimedia

The multimedia test in SiSoft Sandra, performs calculations on a 2D figure. The result (it/s) is Mandelbrot iterations per second, and once again a higher value is better.

Again we have nothing to compare it with, but the numbers here can be used for direct comparison with any other device you might want to look at.

RAM SiSoft Sandra Memory Bandwidth

SiSoft Sandra’s Memory Bandwidth benchmark is used to measure RAM performance. A higher value is better.

RAM performance is quite good. It seems Lenovo are keeping their promise and we have a product with no obvious weaknesses. It seems like a very nice device and the results are quite satisfactory.

Hard drive performance - SiSoft Sandra Harddisk Read

SiSoft Sandra’s hard drive test module is used to measure the hard drive performance.

The hard drive gets past the 50 and things start to look up. It does very well for a 5400RPM hard drive, and it certainly shows in day to day tasks. It is quick and easily retrieves data tucked far away.

GPU performance - 3Dmark

The 3Dmark tests show the performance in DirectX 9 and paints a picture of how well the computer does in newer games and programs. No tests have been run in DirectX 10.1, though both GPUs support it.

The Lenovo has the option of switching between powersaving and high performance graphics. That means it can run even newer games quite well, or you can choose to extend the battery life if you are on the go. It is great to have the choice and it is easy to do with the button at the front.

Here you can clearly see how the high performance easily sweeps away most others in this segment. It is also important to remember we are actually dealing with a both mobile and thin device. Great stuff.
