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.

- 2. Cuprins ● Overview ● New 22nm technology ● New technologies ● Integrated Graphics Processor ● Benchmarks ● Conclusions
- 3. Overview Who is Intel? World's largest and highest valued 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”
- 8. traditional transistor Tri-gate transistor 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% New 22nm technology
- 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 Higher 3D performance with the new integrated graphics processor IPC improvements in Cores Digital Random Number Generator
- 12. New technologies Enhancements to ISA for SSE for graphic processing - Float16 format conversion instructions Supervisory Mode Execution Protection Improved power management Fast acces to FS and GS base registers
- 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 - available for 32-bit and 64-bit OS New technologies
- 15. Power management improvements - Power off DDR I/O when in idle state - configurable TDP / low power mode - lower choices for system agent operating voltages - power aware interrupt routing(PAIR): chooses best core to service interrupt based on optimization mode (power vs performances) - optimized voltage choice for all operating freq points New technologies
- 16. Integrated graphics processor More execution units (up to 16) on chip Higher 3D performance DirectX 11, OpenGL 3.1, OpenCL 1.1 support More performance for gaming experience Enhanced technologies: - Quick Sync video - InTru 3D - Intel HD Graphics - Clear video HD
