Recently I found a test about the performance between ICH 9R and ICH 10R. Very interesting while surprising. Have a look.

main hardware configuration:

Seagate ES.2 250GX4 Raid 0

DRAM: DDR2 1000 2GBX4

ICH 9R:

1

1

ICH 10R:

10

10

Seemingly, ICH 9R enjoys undeniable advantage. Is it due to firmware/software immaturity or the fact that ICH 10R is nothing but a brand new named ICH 9R with somewhat degraded performance? Only joking.

Nevertheless, looking into Intel’s history, we can safely expect future performance of the latest ICH improve by a impressing margin.

So it is not always the fact that the latest must be the best.

Sometimes they are, while sometimes they are really not.
