Intel Pentium dual core and core 2 duo are two of the most common processors in the market at present. But which is the better one for you? Read this Techspirited article to find out…
They sound the same – dual core and core 2 duo – come from the same fabled stable of Intel, and are widely used all over the world. What could possibly account for the difference between the two? While it may not seem so, there are a few points which will lay to rest this debate once and for all.
How do the two processors rate in the bust-up? Let’s check it out…
Architecture
Dual Core: The dual core is the older of the two having an architecture that sports two cores on one processor, but its older technology puts it in a position of disadvantage.
Core 2 Duo: The core 2 duo two has two cores on the same processor. However while the architecture sounds vaguely the same, it is more advanced than the dual core processors.
Winner: Core 2 Duo and its new, advanced architecture.
Performance
Dual Core: This is without a doubt one of the best Intel processors, however it lacks the bite in terms of performance, when pitted against the much more advanced core 2 duo.
Core 2 Duo: This newer processor beats the dual core in all bench-marking tests and therefore performance-wise, is definitely the better pick.
Winner: Core 2 Duo thanks to its advanced architecture.
Heat
Dual Core: Compared to the previous ones, the Pentium dual core is a processor that produces very little heat.
Core 2 Duo: The core 2 duo takes cool performance one step further producing even lesser heat.
Winner: Core 2 Duo.
Power Consumption
Dual Core: Extremely power-efficient processor which has a maximum TDP of an astoundingly low 15 watts.
Core 2 Duo: Power efficient enough, but the 65 watts of maximum TDP are nowhere as low as the dual core.
Winner: Dual core for its efficient use of power.
Clock Speeds
Dual Core: Acceptable enough clock speeds of about 2.33 GHz for the best ones.
Core 2 Duo: Slams the opposition clocking speeds of 3.33 GHz clock as seen of the higher end ones.
Winner: The Core 2 Duo.
Price
Dual Core: Older model processor, so available pretty cheap nowadays.
Core 2 Duo: Comes at a premium which is nearly double the price of the dual core.
Winner: The Dual Core is older, but cheaper.
The final verdict? Well, the Core 2 Duo is a better performer at a higher price. To choose between the two, you need to decide what you want to use your computer for, because ultimately, it is the actual intended use which will help you finalize the processor. A dual core processor is decent enough for routine tasks like MS Office applications and Internet browsing. The Core 2 Duo, on the other hand, shows better functionality when it comes to bigger, more processor-intensive programs and applications.

10 Difference Between Dual Core And Core 2 Duo Processors
Computers have evolved fast from the time they were introduced. Computers were originally launched to be able to solve mathematical applications. These computers were slow to process data and could only run one operating at a time, which means another action or operation had to wait for one operation to become over, before another operation could begin. These were known as single core processors. The demand for faster technology required that the processor companies make faster processors which higher clock speeds. Once a maximum clock speed was achieved, the manufacturers tried increasing the performance of their products by adding more cores to a single chip. These became known as multi-core processors and include dual core, quad core, hexa-core and octa-core processors.
Dual core technology refers to two individual
microprocessors on a single die cast chip. This is essentially two processing
units (CPUs) in one. The advantage of a
dual core chip is that tasks can be carried out in parallel streams, decreasing
processing time. Core Duo was simply 2 Pentium processors on a single chip. As
the company began advancing processor technology making it faster and better,
they decided to differentiate it from their first generation by labeling them
Core 2 Duo. The 2 in the name refers to the 2nd generation of
processors. Basically, the difference between dual core processors and the Core
2 duo processors is just in the semantics as Core 2 Duo is simply a name given
to a more recent family of dual core processors.
What Is Dual Core?
Dual core processors is a CPU that contain two processors or
‘’execution cores’’ in the same integrated circuit. Each processor has its own
cache and controller, which enables it to function as efficient as a single
processor.
Given that the two processors are linked together, they can perform
operations up to twice as fast as a single processor can.
While a dual core system has twice the processing power of a
single-processor machine, it does not always perform twice as fast. This is
because the software running on the machine may not be able to take full
advantage or both processors. Some operating systems and programs are optimized
for multiprocessing while others are not, though programs that have been
optimized for multiple processors will run especially fast on dual core
systems. The Intel Core Duo, the AMD X2 and the dual-core PowerPC G5 are all
examples of CPUs that use dual core technologies. These CPUs each combine two
processors cores on a single silicon chip.
What You Need To
Know About Dual Core
- Dual core is the generic name given to
processors that have 2 cores in a single silicon chip. - It comes under Multi core processor.
- In comparison with previous processors, Dual core
is better than all.
- In Dual core processor, there is 3 MB of L2
cache memory. - In Dou core processor, we can overclock the CPU
up to 3.12 GHz (approximate value). - Duo core processor has two complete execution
cores. - All Core 2 Duo processors are dual core.
- Example include: Intel G530 Dual Core.
What Is Core 2
duo?
Core 2 duo is the name given by Intel to its second batch of
dual core processors. The Core 2 duo is a 64 bit dual core processor. This means two processor cores work inside a
Core 2 Duo in parallel. The Core 2 Duo was introduced on July 27 2006 as a
direct successor of the Core Duo. Each core is based on the Pentium M micro
architecture. When compared to the old Net burst architecture of the Pentium 4,
the cores in the Core 2 Duo have short pipelines and as a result, the maximum
clock rate is lower but the performance per clock is significantly higher.
However, while the architecture of Core 2 Duo sounds vaguely
the same with that of Core Duo, Core 2 Duo is a more advanced version than the
dual core processors.
Core 2 Duo processors are much popular these days because
they have more powerful Dual Core chip, best execution time and consumes less
power in comparison to other version of Intel Core. There are also no
overheating issues, as they run cool and have a perfect over-clock.
What You Need To
Know About Core 2 duo
- Core 2 duo is the name given by Intel to its
second batch of dual core processors. - It is the extensive version of Dual core
processor. - Core 2 duo has better performance than Dual core
as it has better overclock ability than Dual core. - In Core 2 duo processor there is 6 MB of L2
cache memory. - In Core 2 Duo processor, we can overclock it up
to 4.0 GHz. - Due to high clock speed/overclock ability, it
can execute multiple task paralley. - Not all dual core processors are Core 2 Duo.
- Example include: Intel Core 2 duo T8100.
