Intel details upcoming new processor generations

Marking the next step in Intel's "tick-tock" product strategy and

cadence to deliver a new process technology with an enhanced microarchitecture

or entirely new microarchitecture every year, Intel Corporation will begin

producing its next-generation Penryn family of processors in the second half of

this year. These new processors benefit from enhancements to the Intel Core

microarchitecture and also Intel's industry-leading 45nm Hi-k process technology

with its hafnium-based high-K + metal gate transistor design, which results in

higher performance and more energy-efficient processors.

Intel has more than 15 45nm Hi-k product designs in various stages of

development, and will have two 45nm manufacturing fabs in production by the end

of the year, with a total of four in production by the second half of 2008 that

will deliver tens of millions of these processors. Below are many of the details

of the Penryn processor family and a glimpse into some of the key features of

Intel's future generation of processors, codenamed Nehalem.

A Range of Products -- Six Penryn family processors, including dual and

quad-core desktop processors and a dual core mobile processor are all under the

Intel Core processor brand name as well as new dual and quad-core server

processors under the Intel Xeon processor brand name. A processor for higher-end

server multiprocessing systems is also under development. As previously noted,

Intel already has a total of 15 45nm products scheduled.


45nm next-generation Intel Core2 quad-core processors will have 820 million

transistors. Thanks to our high-k metal transistor invention, think of 820

million more power efficient light bulbs going on and off at light-speeds. The

dual-core version has a die size of 107mm2, which is 25 percent smaller than

Intel's current 65nm products - and quarter of the size of the average U.S.

postage stamp - and operate at the same or lower power than Intel's current dual

core processors.

The mobile Penryn processor has a new advanced power management state called

Deep Power Down Technology that significantly reduces the power of the processor

during idle periods such that internal transistor power leakage is no longer a

factor. This helps extend battery life in laptops. This is a major advancement

over previous generation industry leading Intel mobile processors.

For the mobile Penryn processor, Intel has enhanced the Intel Dynamic

Acceleration Technology available in current Intel Core 2 processors. This

feature uses the power headroom freed up when a core is made inactive to boost

the performance of another still active core. Imagine a shower with two powerful

water shower heads, when one shower head is turned off, the other has increased

water pressure (performance).

Penryn includes Intel Streaming SIMD Extensions 4 (SSE4) instructions, the

largest unique instruction set addition since the original SSE Instruction Set

Architecture (ISA). This extends the Intel 64 instruction set architecture to

expand the performance and capabilities of the Intel Architecture.
