ASUS Sneak-Previews P7U Series Motherboards, Based on Intel P55 Platform

During the ongoing CeBIT event, ASUS has two of its newest motherboards on display. Their peculiarity lies in the fact that they are based on the Intel P55 chipset, and have the LGA-1156 CPU socket, supporting the upcoming Intel Core i5 series processors. ASUS chose the "P6T" prefix for naming its first generation of LGA-1366 motherboards based on the Intel X58 chipset. With LGA-1156 and Intel P55 chipset, the company plans to use the "P7U" prefix. The two motherboards on display are the P7U and P7U Pro.

Both motherboards have identical PCB layouts, except for the P7U having a few features toned-down. Both use a (3+1)+2 phase CPU power circuit. Both feature 4 DDR3 DIMM slots for dual-channel memory. Six SATA ports, a PCI-E x4 and a number of PCI-E x1 slots make for the rest of the mix. While the P7U Pro features two PCI-E 2.0 x16 slots (which arrange as x8, x8 when both are populated), the P7U features a single PCI-E 2.0 x16 slot. Both models feature ASUS-exclusive features such as Turbo-V that allows on-the-fly overclocking, ExpressGate that is a basic instant-on OS, and the EPU power management feature.

I wonder why they have gone back to ugly yellow. Their P5Q boards are some really nice looking ones. P55 was gonna be my next upgrade with a 32nm CPU, but I dont want that in my case! :p

I would guess they are prototypes?

I'm guessing these are entry-level. Sort of like how P5K and P5K SE are entry-level P35 motherboards that come with the yellow PCB.

I know, but even entry level P45 Asus boards have the black PCB. :(

P55 isn't exactly a successor to P45. It succeeds P43 (that segment). P57 succeeds P45, though it releases after P55.

Didnt know that! :rolleyes:

Why couldnt they stick with Px5, Px3, so as not to make things confusing :shadedshu

So P53 superceeds P43, P55 superceeds P45, etc.

P57 is a superset of P55, though you can't really find a feature that matters to users like us.

It seems P57 has no onboard video support, supports braidwood and 2x8 PCI-E.

One thing I dont get, is how CPU "talks" to the rest of the system if it has no QPI.

CPU has QPI. QPI is what connects the on-die processing complex to the NB complex (two dice on a package). The NB complex gives out a DMI connection to the P55 chipset in the same way an X58 communicates with an ICH10. The NB complex holds the PCI-E controller, and hence connects directly to PCI-E devices. Some PCI-E devices are connected to the 8-lane PCI-E hub the P5x holds. CPU talks to the memory directly. P5x connects to the LPCIO. An AGESA-like method initiates all components and gets them to communicate each time the system POSTs.

Very ugly motherboard. The IO plate in the back is going to look bad, as there is like a 3 x 1 inch block that has nothing on it.

Thats what annoyed me with this. I wonder what the name of that colour is ... sick or vomit :confused:

it looks like intel is going in another direction.
new chipsets on different sockets, so that means if you are a high end user then 1366 is for you and this is the platform you should be on.
and socket 1156 will be for mainstream.

i find that good only thing that sucks is that your upgrade options will be limited.
