Intel has increased its DDR2 memory support to 800 MHz with the P965 Express chipset, putting Intel's latest and greatest at par with AMD's Socket AM2 Athlon64's. Intel calls the new memory controller FMA or 'Fast Memory Access' and gives the system a maximum theoretical bandwidth of 12.8GB/s. Below is breakdown on the full feature set of the Intel 975 / 965 Express series chipsets, including the P965 Express which is used on the Asus P5B Deluxe/WiFi-AP motherboard.

Initially Intel's P965 Express chipset only supported a single PCI Express x16 videocard, however most current motherboards feature two physical PCI Express x16 slots. Given that the ICH8R southbridge has six PCI Express lanes, these have been utilized to support the second PCI Express x16 slot with 4 PCI Express lanes. It's not as ideal as both videocards received the full 16 PCI Express lanes each, but it works well enough with conventional videocards. The Asus P5B Deluxe/WiFi-AP is one of the Intel P965 Express motherboards with two physical PCI Express x16 slots.

A dedicated 2GB/s I/O bus connects the Intel P965 Express Northbridge and ICH8R Southbridge together, which might be a little tight if you have many high bandwidth devices installed but should be just fine for the average user.

The Asus P5B Deluxe/WiFi-AP motherboard comes installed with the ICH8R Southbridge which includes a ton of goodies. There are six 3GB/s Serial ATA II channels (which support RAID modes 0, 1, 5 and 10) as well a 7.1 channel Intel Azalia high definition audio, 10 USB 2.0 ports in total (split between headers and the I/O slot), six PCI Express x1 lanes, and an integrated Intel Gigabit MAC that runs through the PCI Express bus.

Noticeably lacking from the chipset itself is parallel IDE support. This is forcing many motherboard manufacturers to integrate a standalone IDE controller onto their motherboards (as has been done here) so consumers have something to plug their optical drives into... A block chart of the Intel P965 Express chipset's major features is illustrated below.

Luckily parallel IDE technology isn't overly expensive to add to a motherboard. While I admit that Intel is the leader in computer technology, the notion that it has ceremoniously done away with IDE in one fell swoop seems a bit premature.
