What happened to the SIS Quad Channel RDRAM P4HT chipset?
Basically the SIS R658 was announced back in 2003 but saw no release as it was replaced with the R659 in 2004 and the R659TX for Q1 2005 the latter being able to provide the Intel Pentium 4 with Hyper Threading the following support:
800Mhz FSB (possible 1066FSB support)
Four 16bit channels
PC 1600 RDRAM support
PCI-Express X-16 support (no AGP support)
With Intel Prescotts being slightly bested in some benchmarks by competing AMD 64 processors don't you think that having a RDRAM mobo with quad channel support would give the Prescotts a shot in the arm lead?
Unfortunately AMD 64 cpus cannot use RDRAM so even though some still hate the memory company you cannot deny the performance lead it game Intel back in the days so please don't turn this into an Intel vs AMD topic since this is only for Intel cpus.
Then there is the possible arrival of official support from Intel of Rambus Inc.'s XDR-DRAM (get it XD-RDRAM) providing even more bandwith increases once either the dual core Pentiums are released or the P4HTs with 2MB of L2 cache.
Also with the knowledge of the Pentium M with its 2MB L2 cache being a performance demon wouldn't it make sense for SIS to also make a quad channel RDRAM P-M chipset?
