Much time has already gone since our last tests of modern IA32 chipsets. A lot has changed since then. Intel launched a couple of processors with an enhanced Coppermine core, 133MHz FSB has almost become a standard solution, Microsoft released a new operation system - Windows 2000, which is now quickly gaining popularity. All these events of the computer market made us once again turn to the problem of choosing the optimal mainboard, especially since this is a really hard choice to make today. The main problem is to choose the most optimal set of core logic, the mainboard will be based on. If we agree not to take into account chipsets with integrated graphics core, then the main chipsets for Slot 1/Socket 370 processors will be: a getting more outdated Intel 440BX, super fashionable Intel 820 and alternative VIA Apollo Pro133A. So, in the present article we are going to compare these chipsets and to take a look at their performance. We will try to see all cons and pros of each solution mentioned above. That´s why the tests will be carried out for processors on Coppermine core in Microsoft Windows 2000.
