INTEL 925XE and FSB1066 Information
Shorty
Manchester, UK Icrontian
The 925XE is the twin of 925X, but it finally supports FSB1066. As the Front Side Bus works in QDR mode (quad data rate or 'quad-pumped'), it can transmit four times the data than a single transmission. Accordingly, marketing folks like to call it a 1,066 MHz bus.
The bandwidth of FSB1066 is 8.5 GB/s, as opposed to the 6.4 GB/s with FSB800. Running at Dual DDR2-533, the system is able to run FSB and RAM synchronously, as both the total bandwidth and the basic clock speed are the same.
There is, however, one thing that Intel distinctly ignores in its roadmaps: There is no mention of DDR2-667 memory, although all three DDR2 speed grades have been standardized by JEDEC in January 2004. As more and more 667 DIMMs are becoming available, we suppose that Intel will end up supporting the faster memory. For one thing, the benchmarks clearly benefit from it (see below), and for another, the chipset did not cause any problems running at up to DDR2-740. Finally, motherboard makers don't even need to redesign their boards.
It's not entirely clear, though, as to why Intel will still offer the 925X even after the 925XE becomes available.
When the 925XE is launched, Intel will also release 915GV at the same time. This one is a 915G without x16 PCI Express interface. There will also be a 910GL with support for DDR2 memory removed.
