New to the Q9000 series (Yorkfield)
Yorkfield brings new advancements to the floor including Intel’s 45nm High-k Metal Gate Silicon Technology, and SSE4 instructions for developers.
Intel’s 45nm High-k Metal Gate Silicon Technology
In short, the Intel’s 45nm High-k Metal Gate Silicon Technology uses a few new materials including hafnium.
“Compared to 65nm technology, Intel’s hafnium-based 45nm Hi-k silicon process technology will provide the following
- Approximately twice the transistor density (for smaller chip sizes or increased transistor counts)
- Approximately 30-percent reduction in transistor-switching power
- Greater than 20-percent improvement in transistor-switching speed or a greater than 5 times reduction in source-drain leakage power
- Greater than 10 times reduction in transistor gate oxide leakage for lower power requirements and increased battery life”
What this means for the end user is lower power consumption and more power in the same sized package. Intel’s 45nm technology shows it’s greatest benefits in it’s laptop processor line, providing powerful processors that use less power and create less heat; not somethings you usually take into high consideration in a desktop, but important nonetheless. In a desktop, 45nm means lower power requirements saving you a bit of money on your power bill, and producing less strain on your power supply.
Intel has also introduced their new SSE4 instruction set for developers.
“Unlocking performance and energy efficiency with new instruction set innovations. Integrated into Intel® processors based on Intel® 45nm high-k metal gate silicon technology, Intel® Streaming SIMD Extensions 4 (Intel® SSE4) instructions are Intel’s most significant media instruction set architecture (ISA) advancements since 2001.
These new instructions build upon the Intel® 64 architecture ISA and enable Intel processors to deliver superior performance and energy efficiency to a broad range of 32- and 64-bit applications including:
- Video encoding and processing
- 3-D imaging
- High-performance applications
Intel SSE4 is the result of continued work with the ISV community to deliver instruction set extensions that allow developers to easily enhance their products while maintaining the necessary application-level compatibility across processor generations.”
With SSE4, developers can make their apps perform faster in the aforementioned categories.
