Intel Delays Lynnfield platform

If you've been waiting patiently for the release of the Core i5 processors and the p55 motherboards it may be time to twiddle your thumbs a little longer.

These going to have an upd8 over ICH10R similar to previous x/p releases ?

i.e. x48 would have ICH9 p45 would have ICH10 (in the main)

The Core i5 platform consists of a single controller hub, very much like some boards with nVidia's nForce MCP's. I/O Device support and RAID will be integrated into the P55 chipset, removing the need for a separate ICH chip.

Ah ic, so as opposed to the x58 having the ICH10R, the p55 will have what's on the p55 ?

The P55 chipset is supposed to integrate sufficient PCI-E 2.0 lanes for 1 x PCI-E 16x or 2 x PCI-E at 8x/8x, no memory controller like i7 as it's integrated to the CPU and then there's support for whatever many USB 2.0 ports (12, maybe 14?), a number of SATA II ports, RAID and Gigabit LAN. I'd expect USB/SATA peformance to be very much like ICH9R/ICH10R.

Jeez that sounds like they're asking alot of the chipset tbh. I'd like to see this tested.

It's nothing out of the ordinary to be fair. Motherboards as far back as AMD's nForce 3's for Socket 754 and 939 had a single chip MCP, which handled I/O Devices as well as AGP support (nForce 4 had PCI-E lanes). It's not too tricky to make a single chip solution, especially once the memory controller is out of the equation.

The likes of those older chipsets used to bring massive complaints about the use of mere pci cards, in particular soundblaster or anything requiring dma. Raid cards/drive controllers were an issue as I know myself ontop of soundblaster live.

We going to experience potential dma problems with this arrangement ? Going back to managing irq assignments and latencies with their drawbacks to oc'ing ?
