Pentium 4 with single channel Rambus
Although the i850 Tehama chipset supports dual memory channels, what would happen if the bandwidth was reduced to one single channel? Well, if you were intrigued by the memory bandwidth & latency exploration posted on [H]ard|OCP but lamented the fact that Rambus was given the brush off, this ZDNet Germany article (Free Translation here) intends to do exactly that by benchmarking a Pentium 4 with only one single channel active with a stick of 256MB PC800 RDRAM. Follow that up with this energetic thread at Ace's Hardware (original post here) where studs like Tim Wilkens and Paul DeMone weigh in with some interesting commentary.
Separately, The Register is reporting on price cuts for Intel processors including the Pentium 4 on December 10.
