Forget PCI Express, it's time for PCI Express 2

Trusted computing, you've heard of it

By INQUIRER staff: Monday 29 August 2005, 10:05
WHILE A LOT of people haven't got themselves fangled up for PCI Express yet, and AGP cards are still selling well, Intel told developers last week to be ready for PCI Express 2.

Ajay Bhatt and Ramin Neshati, who work at the Intel Corporation, divulged architectural extensions for PCIe II, with products expected in 2007-2008.

Features for PCI Express II include better formance at 5GHz PHY, device virtualisation, trusted platforms, and different sizes - or form factors as the jargon goes.

Luckily, you won't have to throw the baby out with the bathwater, because PCIe II will be compatible with PCIe 1.x, using the same power budget and the same clocking architecture. But the silicon cost will be cheaper, and so will the clocks.

A new form factor, or size as it's called in AmerenglishIntel discovered that systems are constrained by jitter and not voltage margins, and hitting the "jitter budget" is a fundamental requirement for version 2.0.

Five GHz devices have to operate at 2.5GT/s or 5.0GT/s. and the transmitter, receiver, reference clock and channel must all be 5GHz capable to get to that kind of performance.

The virtualisation feature will allow multiple OSes to run simultaneously and share the platform hardware resources, effectively sharing PCI Express devices.

OS improvements can lead to increased IO attacks on systems, so PCIe II will try and include better trusted computing. There will be a trusted configuration space, and a trusted configuration access mechanism will be included with modifications to the trusted platform module (TPM) to enable that.

Different sizes of devices will be included for wireless radios in the notebook lid. PCIe II may also include two distinct types of connector assemblies.

PCI-X != PCI-Express

No Offence. But I don't trust the source of this artical.

I am trying to work out why we have not heard this from other places.

true why is this not on toms hardware or http://betanews.com

Also PCI-X and PCI-E is 2 totaly different things.

[DJ-CHRIS]

I have heard of PCI-E II

And mislabelling PCI-E as PCI-X i am coming to shoot you.

Whoops, typo lol.

Intel has always attempted to prematurely force technology on the market...just look at RAMBUS and DDR2, it never works in their favour

[Apokalipse]

PCI-X is a 64-bit (or sometimes 128-bit) version of PCI

and why the **** push people to go to PCI-E II?
graphics cards, even the 6800's, struggle to use the full AGP 4x bandwith. if you test one in AGP 4x and AGP 8x, the difference is maybe a couple of fps.
and PCI-E already has a lot more bandwith than AGP 8X

plus, the majority of other expansion cards (like network cards, sound cards) do not even use the full bandwith of normal PCI.

in reality, the difference PCI-E II will make against PCI-E is really next to nothing, and probabbly will be for at least 3-4 generations of graphics cards

Intel is to far ahead themselves and the technology IMO. They need to slow down a bit and work like AMD does. It seems like Intel is out to make money whereas AMD is out to make logical components at logical times while not caring about $.
