In this demo we can see a short fight against zombies, which are defeated with the help of a gravity gun loaded with anything available at hand. This weapon should really load the CPU. Moreover, we also witness a few huge explosions, which blast effect scatters all objects and characters around.
The situation is very similar to what we have already seen in the previous demo. AMD processors are again far ahead their rivals from Intel due to bigger computational potential.
When we run the tests in “heavier” resolution, LGA775 platform manages to significantly improve its performance due to PCI Express x16 bus. Pentium 4 processors tested in Socket 478 platform, which uses AGP 8x bus cannot boast the same success. For instance, Pentium 4 Northwood working at 3.4GHz clock frequency is totally defeated by AMD Athlon 64 3200+, while Pentium 4 on the Prescott core working at the same core frequency even falls behind Athlon 64 3000+. So I wouldn’t be so enthusiastic about the Pentium 4 platform performance in Half-Life 2: the victory here is not absolutely fair I should say.
