An octa-core processor contains eight independent processing cores on a single chip. This allows multiple tasks to be performed simultaneously, improving efficiency. Some benefits of octa-core processors include increased multitasking ability, better performance for resource-intensive apps, lower power consumption, and a generally smoother experience for activities like web browsing, gaming and video playback. Trends in the microprocessor field have moved from dual-core to quad-core, penta-core, hexa-core and now octa-core designs, packing more cores onto a single chip to enable parallel processing.

3. INTRODUCTION
A Multicore processor is a single computing
component with two or more independent central
processing unit.
They have several independent cores which works
together in parallel.

4. MULTICORE PROCESSOR
• A Multicore microprocessor is
one which combines two or
more independent processor
into a single package, often a
single integrated circuit
• Eg:Dual core contains only 2
independent microprocessor

6. EXAMPLE-DUAL CORE

7. TERMINOLOGY

8. Comparison

9. features of multi-core
technology
• Works faster for certain program
• More features can be added to the computer
• The signals between different CPUs travel
shorter distances, therefore they degrade less
• The computer needs less power because it can
turn off some sections if they aren´t needed

10. downside of multi-core
technology
• The speed that the computer works at
depends on what the user is doing with
it.
• They cost more than single core
processors.
• They are more difficult to manage
thermally than lower-density single-core
processors.
• Not all operating systems support more
than one core.

11. Trends in the
microprocessor worlds

chip).
2. dual core chip is that tasks can be
carried out in parallel streams,

15. Dual Core Processor
Performance
a. each core handles incoming data strings
simultaneously to improve efficiency.
b. advantages of a dual-core processor over
the single processor is
a performance gain.
c. amount of improvement varies both with
the hardware and software involved and
also with the particular task the user is
doing.

16. Dual Core Processor Speed
• and a dual core system is faster than a single-
core system, when everything else is equal.
• SMT enables parallel multi-threading
increases the speed of processor
• multi-core processor is that it each processor
acts independently from one another

17. CLOCK SPEED
• Clock speed is a measure of how
quickly a computer completes basic
computations and operations
• most clock speed measures is very
high, the terms megahertz and
gigahertz are used
• A megahertz is one-million cycles
per second, while a gigahertz is
one-billion cycles per second.
• So a computer with a clock speed
of 800MHz is running 800,000,000
cycles per second, while a 2.4GHz
computer is running 2,400,000,000
cycles per second.

18. Benefits of dual core
1. Increased performance: latest dual-core,
64-bit computing for large workloads
and data-intensive applications
2. Increased memory: up to 32GB of
memory capacity
3. Increased storage: up to 600GB Serial-
Attached SCSI (SAS) drives at 15K rpm,
4. Increased reliability: fully buffered
DIMMs simultaneously boost memory
5. Increased flexibility: achieve greater
utilization applications with Intel
Virtualization Technology
6. Reduced cost: there is no added cost of a
second physical processor.
