What is a Processor
•Processor is the portion of a computer system that carries out the
instructions of a computer program, and is the primary element carrying
out the computer's functions. This term has been in use in the computer
industry at least since the early 1960s .
The Process
Process is a program in execution .A process is more than the program code which is
known sometimes as a text section.
A multi-core processor is a single computing component with
Multi-Core two or more independent actual central processing units (called
(microarchitecture) "cores"), which are the units that read and execute program
instructions.
Interaction with the Operating System
• OS perceives each core as a separate processor
• OS scheduler maps threads/processes to different cores
• Most major OS support multi-core today: Windows, Linux, Mac OS X, …

Nehalem (microcomputer)
Nehalem is the codename for an Intel processor microarchitecture, successor to the Core microarchitecture.
• Nehalem processors use the 45 nm process.
• The first processor released with the Nehalem architecture was the desktop Core i5, which was released in
November 2008.
Core i5 Processors
• Intel has just announced their latest lineup of Core i5 11 gen

processors.
• Sandy Bridge, as the new architecture is called by engineers is Intel's
new microarchitecture, following Nehalem.
• The new processors are produced on Intel's 32 nm production process
which has reached maturity over the last few months.
• The core i5 line consists of three separate series of processors
with
i) DualCore Core i5 Processors
ii) QuadCore Core i5 Processors
• The DualCore Core i5 , as well as quad cores come with 4
threads each.
Core i5 • The clocking frequency ranging from 2.933 GHz to 3.2 GHz
processor • 4 MB to 8 MB L3 cache
• Direct media interface
• Intel HD graphics
• Intel smart cache technology
• Hyper-threading enabled
• i5 chips are faster than the i3 chips
Core i5 Quad-
Core Structure
Cache Memory
• In addition to generally faster base clock speeds, Core i5 processors have larger cache (on-board
memory).
• help the processor deal with repetitive tasks faster.
• If you're editing and calculating spreadsheets, your CPU shouldn't have to reload the framework the
numbers sit in. This info will sit in the cache so that when you change a number the calculations are
almost instantaneous.
• Larger cache sizes help with multitasking as well, since background tasks will be ready for when you
switch focus to another window.
• On currently available desktop processors, i5 CPUs have 3MB to 8MB of L3 cache, while i7
processors have 8MB to 15MB.
Turbo Boost feature
• Turbo Boost refers to Intel's "overclocking" feature built into its processors.
• It allows the processor to run faster than its base clock speed when only one or two processor cores
are needed (like when you're running a single-threaded task that you want done now).
• This provides users with the opportunity to turn off a core if it’s not being utilized.
• Both Core i5 and Core i7 processors use Turbo Boost

• Intel Hyper-Threading uses multi-threading technology to make a processor appear to
have more cores than it physically has to the operating system and applications.
• Hyper-Threading technology is used to increase performance at multi-threaded tasks.
• The simplest multi-threaded situation is a multi-tasking user running several programs

simultaneously, but there are other tasks that take advantage of Hyper-Threading
• For instance multimedia operations (like transcoding, rendering, etc.) and Web surfing
(loading different elements like Flash content and images simultaneously).
Integrated Graphics
• Integrated graphics built into the processor core itself.

• Previous Intel integrated graphics were built onto the motherboard chipsets,
rather than on the processor.
• Intel HD Graphics 2000/3000 in currently shipping Sandy Bridge processors.
• Integrated graphics saves power, since there won't be an extra graphics chip on
your laptop or desktop’s motherboard using power.
• Multi-core chips an important new trend in computer architecture
• Several new multi-core chips in design phases
• Parallel programming techniques likely to gain importance
• Turbo boost feature is implemented after Core i5 design. So it is main

Conclusion
feature of corei5.
• Core i5 has Dual and Quad Core Both.
• Core i5 is made for mainstream users who care about performance and
core i7 is made for enthusiasts and high end users.
Thank you
