Ivy Bridge was Intel's 3rd generation Core processor introduced in 2012. It was their first 22nm processor, providing better performance while being more energy efficient. Key features included revolutionary 3D Tri-Gate transistors for the first time, integrated graphics with up to 16 execution units, and various power optimizations. Benchmarks showed significant gains in performance and reductions in power compared to previous generations.

semiconductor chip maker
World leader in microprocessor manufacturing
with about 80% market share

4. Overview
Ivy Bridge - 3rd
generation of Intel Core
processors introduced in 2012
first 22nm processors
better performance, more energy efficient

5. Overview

6. New 22nm technology
Intel continues its strategy to introduce new
technology every 2 years

7. New 22nm technology
Revolutionary 3D Tri-Gate transistors used
The transistor forms conducting channels on
three sides, instead of two of a vertical fin
structure, providing “fully depleted operation”

New 22nm technology

9. ● Dramatic performance gain at low operating
voltage:
- about 37% performance increase at low
voltage
- more than 50% power reduction at
constant performance
● improved switching characteristics : on
current - off current
● higher drive current for a given transistor
● low cost adder : only 3%

10. New technologies
Already known Hyper-Threading, Turbo-
Boost, Virtualization, Smart-cache and other
technologies are used in Ivy bridge imported
from previous generation

11. New technologies
What is new?
22nm technology provides higher performance
at lower power

13. new Digital Random Number Generator
instruction
- returns a random number 16, 32 or 64 bit to
the destination register
- high quality, high performance
- standard compliants
- instruction available at all privilege levels
New technologies

14. Supervisor Mode Execution Protection
- prevent execution out of untrusted application
memory while operating at more privilege lvl
