Introduction of a processor
Before discussing about i3 processor, let a small introduction of processor.
A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.
The term processor has generally replaced the
term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor.

Brief introduction about i3 processor The only question I have is if there's any
advantage to using a Core i3 over a Core2Duo.
The Core i3 is a 3.2 GHz dual core chip, and it's quite a big improvement over the Core2Duo. It's a good 700 MHz faster, much faster bus with significantly faster RAM.
The first Core i3 processors were launched on January 7, 2010.

Single-core CPU chipthe single core
6
Multi-core CPU chip
The cores fit on a single processor socket .Also called CMP (Chip Multi-Processor
Task level and Tread level parallelism.

Some features of i3
Intel® Hyper-Threading Technology (Intel® HT Technology).Intel® Virtualization Technology (Intel® VT).
Intel® Smart Cache.
Execute Disable Bit.
Intel Smart Memory Access.
9
Intel Hyper-Threading Technology
Single core can run multiple thread.
Simultaneous multi threading.
Increase throughput and efficiency.
Turbo Bust Technology.
Thermal Design Power(TDP)

Intel® Virtualization Technology (Intel® VT)
Speeding up the transfer of platform control between the guest operating systems (OSs) and the virtual machine manager (VMM)/hypervisor.
Enabling the VMM to uniquely assign I/O devices to guest OSs
Optimizing the network for virtualization with adapter-based acceleration
13
Server Virtualization
Desktop Virtualization
Intel® VT Flex Priority
Intel® VT Flex Migration
Its also provide help to run 32bit O.S. on 64 bit
Types of Hypervisor
Type 1: oracle VM server for SPARC
Type2:VMWare workstation , Virtual Box

Intel® Smart Cache
Smart Cache is a level 2 or level 3 cache method for multiple execution cores invented by Intel.
It shares the cache among cores
It decrease the cache miss rate.
It provide peak transfer rate of 96GB/sec .
16
17
Smart Memory Access
Improve the performance.
It also include Memory disambiguation.
It aim to locate data as close as possible to reduce memory latency time.
18
19
Execute Disable Bit.
Malicious buffer overflow attacks pose a significant security threat to businesses.
These attacks cost businesses precious productivity time, which can equal significant financial loss.
It allows the processor to classify where application code can execute and where it cannot in the memory.
When a malicious worm attempts to insert code in the buffer, the processor disables code execution.
