Toms Hardware Guide has been experimenting with the predecessor of i875P, the Granite Bay or E7205 chipset which features a Dual DDR interface. While it is significantly cheaper than i875P based motherboards in can provide as much performance. Motherboards used to confirm this were the Asus Asus P4G8X and P4C800. Currently, Intel is promoting the 875 chipset as the ultimate in chipsets. Intel has devoted the longest development time to this chipset, ever since components of this type have been available from Intel. The chipset that is sold under the code name "Canterwood" is supposed to enable very fast memory transfer performance (bypass paths and faster paths), thanks to PAT technology (Performance Acceleration Technology). Our tests show that the old Intel 7204 chipset runs stably with a new P4 processor at an FSB clock of 200 MHz. This brings up the question of what advantages the new high-end 875 chipset really can offer over the old 7205.
