We will start by running several CPU benchmarks to get an idea of what the processing power is with the Intel Core i7-5600U processor.

Cinebench 11.5

CINEBENCH is a real-world cross platform test suite that evaluates your computer's performance capabilities. The test scenario uses all of your system's processing power to render a photorealistic 3D scene. This scene makes use of various different algorithms to stress all available processor cores. You can also run this test with a single core mode to give a single core rating.


We get our first look at CPU power in this Cinebench 11.5 benchmark. In our tests we will find that the Intel Core i7-5600U processor only has 2 cores and 4 threads, so in many tests the W540 will come out ahead because it has double the amount of cores.

Cinebench R15

Just like in the Cinebench 11.5 results, we see single threaded scores come very close to the Intel i7-4800MQ that the W540 has.


wPrime is a leading multi threaded benchmark for x86 processors that tests your processor performance. This is a great test to use to rate the system speed; it also works as a stress test to see how well the system cooling is performing.

This test puts a heavy load on the system and can stress the systems cooling ability. We had CPUz open through the whole test and did not see any throttling. This shows again that the W550s has a very robust cooling system inside.


AIDA64 memory bandwidth benchmarks (Memory Read, Memory Write, and Memory Copy) measure the maximum achievable memory data transfer bandwidth.

The W540 we tested had only one stick of RAM installed. The W550s has two sticks of RAM installed so we are seeing about double the memory bandwidth on the W550s.

William Harmon started working with computers back in 2005 and began overclocking all kinds of different setups. My focus back then and even now is extreme cooling using Single Stage Phase units, Cascades and Liquid Nitrogen. During this time I was also in several competitions that GIGABYTE had sponsored, GOOC 2009 and 2010. Using technics in overclocking and cooling that I have learned over the years I started building high speed workstations and servers for clients who needed higher performing systems. Many of these systems are used in high frequency trader companies and work stations used in all kinds of professions. At TweakTown, I provide and develop accurate test and benchmark methods for servers and other equipment to help make purchasing decisions easier.
