Placer, Granite Bay chipsets debut
Just in time for Comdex, Intel has launched its dual-DDR chipsets for its Pentium 4 and Xeon processors. "Placer" is the Xeon chipset, also known as the E7505. "Granite Bay" is the P4 chipset, and as I understand it, Granite Bay is targeted at the workstation market, not mainstream desktop systems. These chipsets have been hotly anticipated because the Pentium 4/Xeon platforms have the processing power and bus bandwidth necessary to really take advantage of additional memory bandwidth.
The gang at T-Break has a review of MSI's Granite Bay board for Pentium 4 chips, and 2CPU.com has some dually Xeon/dually DDR action going with MSI's "Placer"-based mobo. Oddly, neither incarnation of Intel's dual-channel DDR technology performs much better than the 845PE/GE chipsets (you can read our review of those here). Go figure.
