Intel's Dual-Core Core i3 Processor
By Stephen Bucaro
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture.
Core i3 Features
o Integrated dual-channel DDR3 memory controller
o separate DMI interface to peripheral devices
o HD-capable graphics controller
o separate 256 KB L2 cache for each core
o Up to 4 MB L3 cache shared between 2 cores
o SSE4 instructions
o HyperThreading technology
o support for Virtualization
Because Core i3 is entry-level certain features are not supported.
Core i3 Features Not Supported
o Turbo Boost Technology,, which temporary increases frequency of one or more cores, is disabled
o Advanced Encryption Standard (AES) instructions are not supported
o Trusted Execution technology not supported
o VT-d virtualization not supported
Core i3 CPUs for budget desktop use are packaged in Socket 1156 Land-Grid Array (LGA) package.
Core i3 CPUs for budget notebook and mobile use are packaged in BGA-1023 or 988 micro-PGA package.

Al Chartreux says, "I helped a friend put together a build with the Core i3-530. It's a nice machine,
and we're pleased with how it came out and performs. Like all of Intel's desktop CPU's, the Core i3-530
is a quality chip, and at a price of $114.99, certainly among the most inexpensive of Intel's desktop
offerings, which tend to be priced at a range of $150 to $300 for low to mid-range chips, and $310
and higher for high-end chips. At a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running
chip that doesn't gobble down loads of electricity, so those looking for power-efficient, quiet machines
will be happy with it.
