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.”

There is something to be said for the Athlon 64 in terms of longevitiy compared to Intels previous products. ie, as 64 bit OS and applications hit the mainstream over the next few years, those who have a 64 bit A64 will see performance boosts (see link below showing 5-20% boosts in performnace on 64 bit os & software benchmarks).

Naturally core 2 is still faster in 64 bit mode, no question. However, Intel really hasn't had anything of value in the 64 bit world until the last 7 or 8 months. Keep in mind the original 'core duo' was not truly 64 bit.

None of this helps AMD looking forward, except to say that prior to Core 2 AMD was demonstrating a lot of vision in looking to the 64 bit world. It also means the A64 will have much longer legs than its Pentium 4 class rivals :

Core Duo doesn't have 64 bit at all.

If you meant the current Core 2 Duo, yes it does have true 64-bit support. If you are talking about Core 2 Duo having lack of Macro Op Fusion at 64 bit, that's strictly a performance feature. It can run full "AMD64" regardless. The Pentium 4/Pentium D's before 2006 has partial implementation of the 64-bit.

Even then they are still full 64-bit. They are just not full AMD64.
