IBM to enlist high-k metal gate technology with its 45nm chips

Alongside Intel’s news of 45nm process technology, IBM today announced its own 45nm technological advancements that apply to products manufactured in its East Fishkill, NY plant starting in 2008.

Working with AMD and its other development partners including Sony and Toshiba, IBM has found a way to construct a critical part of the transistor with high-k metal gates, that substitutes a new material into a critical portion of the transistor that controls its primary on/off switching function. The material provides superior electrical properties compared to its predecessor, silicon dioxide, enhancing the transistor's function while also reducing leakage.

As important as the new material is the method for introducing it into current manufacturing techniques. The creation of this transistor component with the new material was accomplished by the IBM team without requiring major tooling or process changes in manufacturing - an essential element if the technology is to be economically viable.

“Until now, the chip industry was facing a major roadblock in terms of how far we could push current technology,” said Dr. T.C. Chen, vice president of Science and Technology, IBM Research. “After more than ten years of effort, we now have a way forward. With chip technology so pervasive in our everyday lives, this work will benefit people in many ways.”

I disagree. I have been using a 64-bit OS for years. Further, all my apps are compiled for a 64-bit machine. Linux (Gentoo in particular) were supporting AMD64 in a meaningful way looong before Microsoft, and I've been there getting the benefit the whole time.

To say that Intel was justified in dismissing AMD64 is just silly. Intel tried to downplay the major advancement as long a possible, because it was effecting their precious Itanium line.

I see real world speed boosts of around 5%-10% when running 64-bit, and that is no small change when it comes for free. AMD64 will become the standard (already is), and from now on, instead of saying x86, what people will really mean is AMD64.

true, but what percent of the user base do you represent?

According to 2004 surveys, 2.8% of desktop computers ran a flavor of Linux.

10% of those desktop Linux boxes ran Gentoo (2006 survey).

Which means he represents .28% of the desktop market. :)

Though to be fair, several major distro's have 64bit version available, but not all. So. Maybe he represents 1% or 1.5% of the desktop computer install base. Linux hasn't exploded in growth since 2004, so probably still less than 4% or so of the current market.

In other words, not much. :)
