Unlike the Core 2 processors, the new Core i7 and Core i5 processors have a monolithic design. That means the entire quad-core processor is fabricated on a single die. The quad-core version of the Core 2 processor, on the other hand, combines two dual-core dies in a multi-chip package (MCP). The newer Clarksdale core (powering some Core i5 processors) also uses the latest 32 nm process technology. Finally, the Core i7 and Core i5 processors feature a slew of new technologies :
- an integrated DDR3 memory controller
- a three-tier cache design
- QuickPath Interconnect (or Direct Media Interface for some Core i5 processors)
- Intel Turbo Mode technology (now renamed Intel Turbo Boost)
This article will focus on the mysterious Intel Turbo Boost Technology. It has been bandied about by Intel as a nifty way to improve the Core i7's performance with older applications that cannot fully utilize its four processing cores, but what exactly is it?
