Q: Which Pentium chipset has the best performance?
A: The performance difference of chipset depends on what kind of DRAM they use and the DRAM timing
they support. (They all use PBSRAM, so that the difference is very little at 2nd level cache.)
The following table lists the read timing of current available chipsets. The four digital represents the
clocks needed for 1st-2nd-3rd-4th QWord. Notice that the Intel HX + EDO or SIS 5571+ EDO are
almost the same as VX + SDRAM and the TX + SDRAM has the best performance among Pentium
chipsets. Please note AP57 does not support SDRAM..
