Dear Chipdesigner:

If he was really serious about Sis making better controllers than AMD, all they would need to do is add one or two in their NB part of the chipset. AMD can use off chip memory controllers with HT, cHT is only needed because they connect to off chip caches in the other CPUs. So Sis can prove their memory controllers are superior. They can even be compared to access time wrt remote 2P memory access times. I think that Sis can't do it better than AMD, else they would do it. You know there would be a lot of MB manufacturers that would use a chipset allowing 8 unbuffered DIMMs on a one socket MB. Getting 10.4GB/s BW, 45-50ns on die and 50-55ns access latency off die (off die 16/16HT at 1GHz is slower than on die 32/32HT at 1.8-2.6GHz) with 8GB of LL PC3200 is better than 6.4GB/s,45-50ns and 4GB LL PC3200.

But since Sis doesn't, they likely can't do better and they know it.
