"Mako" details

"Wahoo" details
PCI Express configuration revealed

Chile Hardware has come across more details of AMD’s upcoming RD790 chipset. The RD790 is the successor to AMD’s previously released 580X chipset, formerly known as CrossFire Xpress 3200. This time around AMD is only releasing a new north bridge. The upcoming RD790 is expected to pair with the existing SB600 south bridge.

Nevertheless, the RD790 has plenty of PCI Express lanes to go around. AMD has equipped the RD790 with 42 PCI Express lanes for plenty of expansion capabilities. Thirty-two PCI Express lanes are dedicated to two PCIe x16 slots for CrossFire operation. These lanes can be further divided to deliver four PCIe x8 slots as well. PCI Express 2.0 will be supported as well.

There will still be plenty of PCIe lanes for other devices or even more PCIe slots. As the two PCIe x16 or four PCIe x8 slots only take advantage of 32 PCIe lanes, there are ten remaining lanes with six lanes used for PCIe x1, x2, x4 slots and integrated PCIe devices and another four lanes used for the south bridge interconnect.

As far as processor support goes the RD790 supports HyperTransport 3.0 and Socket AM2+. Socket AM2+ will be the new socket used by AMD’s upcoming Stars core based processors.

It is unknown when RD790 will make its official debut; however, AMD has been shipping reference boards to manufacturers. There are two reference boards available: Mako and Wahoo. Mako is the single processor reference board with support for socket AM2 and AM2+ processors. It will consist of the RD790 coupled with the SB600. The PCI Express lane configuration for Mako is as follows: two full-speed PCIe x16 slots, one physical PCIe x16 slot with four lane signaling for physics, one physical PCIe x4 slots with two lanes shared between Gigabit Ethernet and SATA and one PCI slot.

Wahoo is the new 4x4 reference board powered by a combination of the RD790 and SB600. It will support socket 1207+ processors. Wahoo will feature a slightly different PCIe lane configuration. There will be one dedicated full-speed PCIe x16 slot while the secondary slot can be configured for x8 or x16 signaling. The third physical PCIe x16 slot will have eight PCIe lanes. Lastly it will have one PCIe x1 and one PCI slot.


All PCIe slots on RD790 based motherboards will be compatible with the PCI Express 2.0 specification.

I think you just haven't looked around very much, because TPM modules have been available for several years now on many boards. They're definitely not very common on consumer boards because there's basically nothing in TPM to benefit consumers, but on corporate systems they're pretty standard. Take a look at a Dell or HP business class system and you'll find that they pretty much all have TPM modules at least available as an option if not built-in.

As for what it means, probably dick-all. TPM is almost never used because it can be a HUGE pain in the butt to implement properly! It's also really poorly understood by most people, even in the IT business (hell, some people still think TPM has to do with preventing illegal music downloads or some such nonsense!).
