Sandra is designed to test the theoretical power of a
complete system and individual components. The numbers taken though are again,
purely theoretical and may not represent real world performance. Higher numbers
represent better performance.

The 1.9GHz, quad-core Intel Core i7-3517U processor
inside the Samsung 900X4C-A02 laptop manages good results for mobile processor,
netting 47.9GIPS and 35.24GFlops in Dhrystone and Whetstone sub-tests,
respectively. To put things into perspective, this is about 40% faster than the
older Core i5 750 CPU used in the Samsung R480 notebook.

The 256GB Samsung SSD housed in the slim aluminum chassis
of the NP900X4C-A02 ultrabook is dramatically faster than the old 5400RPM HDD
the 'R480 laptop was built around. In Sandra, the Samsung MZMPC256HBGJ SSD
scores a Read index of 503MB/s!
Let's take a closer look at the SSD performance next with
PCMark Vantage HDD test suite.
