Fujitsu Lifebook NH751 gaming notebook review
As usual, before we start with the benchmarks, here is a more detailed list of specifications about the hardware used to power the Fujitsu Lifebook NH751 gaming notebook, courtesy of tools such as CPU-Z and GPU-Z:
Initially, we were unable to proceed with any of the benchmarks we had installed on the LifeBook NH751, simply because the NVIDIA driver and control panel decided that they did not want to cooperate with us. Indeed, the driver refused to recognize any changes made to its default settings, and every time we attempted to force the system to utilize the discreet NVIDIA GeForce GT525 GPU for our tests, the notebook never failed to switch itself back to the built-in Intel IGP (and disrupting our tests in the process).
As it turns out, the answer to this little problem was both simple and amusing at the same time. Apparently, the factory image that was loaded into our review unit lacked a working driver from NVIDIA to power the GT525; instead, it was Windows' own built-in driver that was driving the GT525, and suffice to say the built-in driver is way too old to support new technologies such as Optimus. Fortunately, after trashing the older drivers and installing the latest stable version of the ForceWare drivers we could get our hands on (which is 275.33), Optimus was up and running without a hitch.
With that said, here are the results of our benchmarking proper:
Battery Eater PRO
Battery life on the Fujitsu Lifebook NH751 when idle is decent, regardless of whether the GT525M or the onboard Intel IGP was accelerating the desktop. In both cases, we were able to clock battery uptimes of more than three hours, although it is clear that the onboard Intel IGP has a slight advantage over NVIDIA's GeForce GT525M graphics card where idle battery life is concerned.
However, things were slightly different in the battery drain tests, where the Intel IGP lost to GT525M by a razor-thin margin. This means that, contrary to popular belief, utilizing the Intel IGP for graphics-heavy tasks will not help a user in gaining the maximum amount of uptime possible from the NH751's battery.
Futuremark 3DMark 11
Considering how the GT525M graphics card used to power the NH751's graphics crunching capabilities is very similar to the GT520M found in the Lenovo IdeaPad Z470 notebook that we had reviewed earlier, we were really not surprised to see the NH751 throwing up a rather low score in the 3DMark 11 benchmark tests. However, while both the GT525M and GT520M only have a measly 96 shaders, the GT525M boasts a slightly larger memory bandwidth of 128-bit, which appears to be the main reason for the GT525M outperforming the GT520M in this test.
Futuremark PCMark 7
However, where overall performance is concerned, the NH751 manages to fare surprisingly well, in spite of it feeling sluggish when executing basic applications and tasks in the bundled Windows 7 operating system. Indeed, with a score of 2196 in PCMark 7, the NH751 definitively has more than sufficient power needed to fulfill its role as a multimedia entertainment notebook, although we'd caution against using it for hardcore gaming on the latest titles available on the market.
