Memory times


which is the faster memory

both are in 2 different computers.

The 2.5 memory has better timings. Timings influence the overal memory performance (as they tell something about how much cycles are required to do certain operations), but other factors are important as well. So it’s pretty hard to tell.

For example: PC2100 CL2 memory has way better timings than PC4200 CL4 memory, but the PC4200 memory (which is not an official standard btw) will beat the #### out of the PC2100 memory (in real life situations; synthetic benchmarks can let the PC2100 win if they want to).
