PCMark benchmarks computer’s performance in office and office-related applications and also produces performance scores for the main subsystems (CPU, memory, graphical, and disk subsystem). PCMark 2005 carries on the tradition of complex benchmarks of the series and uses fragments of real-life applications as tests. This makes it somewhat more relevant for end-users as opposed to fully synthetic benchmarks. After running a series of 11 tests on the different components of the system, the program calculates an overall performance score in units called PCMarks. PCMark 2005 can check a computer out at processing HD video and encoding audio, and offers enhanced tests of the CPU and hard disk under multithreaded load. The overall score is calculated by the formula: PCMark Score = 87 x (the geometric mean of the basic tests), where the geometric mean is calculated as (Result 1 x Result 2 x…) divided by the number of results.

It’s natural that the identical Core 2 Duo T8300 processors deliver identical and high performance. When powered by the batteries, the notebooks lower their CPU clock rates from 2.4GHz to 1.2GHz, which affects the results. The only test where the two notebooks are much different is Gaming but we’ll examine their gaming capabilities in more detail below.

3DMark uses its own rendering engine to create a set of 3D scenes that load the graphics subsystem in various ways.

The GeForce 9300M G proves to be only half as fast as the more advanced 9500M GS. Now let’s check out a few real games.

It’s the same in the synthetic benchmark. Alas, the GeForce 9300M G is capable of running old 3D games only. Quake 4 and Half-Life 2, rather old titles as they are, run too slow on it even. The M50Sv, with the GeForce 9500M GS chip, is twice as fast as the U6Sg in games.

Battery life is just as important a parameter of a notebook as its performance. The notebook’s battery life was measured with MobileMark 2007. We disabled standby and hibernate mode for the test.

The first scenario, Productivity, emulates the user’s working in typical office applications. The load is not constant as the user is frequently distracting from his work. The second scenario measures the notebook’s battery life when the user is reading text from the screen in Adobe Reader. The third scenario is about DVD playback in InterVideo WinDVD.

That’s where the trick with the compact battery shows up. The battery gets depleted in an hour, which is unsatisfactory. You can only use the 3-cell battery in your apartment to carry the notebook from one chair to another. The 6-cel battery improves the result twofold and more, yet the notebook doesn’t make it to 3 hours even with this large and heavy battery.
