VIA's P4X266: The Pentium 4 gets DDR

Memory Bandwidth - Sandra 2001

In theory the dual channel RDRAM solution on the i850 provides about 50% more bandwidth than the P4X266's DDR memory controller when operating at full speed.  SiSoft Sandra's STREAM test actually works very well when attempting to measure bandwidth that's available to applications in real world tests, and these tests agree pretty much with what the specs state: 40% more bandwidth for the i850.  The real question is, do we need 1.6GB/s or will 1.1GB/s do just fine?

The picture doesn't change much here.
