Quad-Core Or Dual-Core: Which One Is Best For Me?

When you plan to purchase a new laptop, one of the most important components is the processor.

When you’re looking at the manufacturer specifications, it can be difficult to know which processor is best for your needs.

If you’re not a computer expert, some of the figures and numbers quoted by laptop manufacturers can be baffling. The main points to consider when choosing a processor are speed, price, and build quality.

To determine whether you should choose quad-core or dual-core, we’ll look at the key features of both to see how they differ.

Quad-Core

Core i5 and Core i7 Review

A quad-core processor is a chip inside your computer that has four separate cores.

Each core works with circuits in the machine such as ports, cache, and memory management.

The two big names in processors are Intel and AMD, and they both manufacture a range of quad-core processors. These brands are trusted by consumers, and you’ll see Intel or AMD processors fitted in the majority of business and home laptops.

Quad-core processors are usually fitted to higher end laptops rather than budget notebooks and Chromebooks. This is due to the budget laptops not needing high performance or the speed that the more expensive machines require.

Components

There are not a lot of components inside a quad-core processor and very little can go wrong with them.

As well as the four cores, there are small pins that connect a circuit board and the processor housing.

Inside the processor there are four silicon cores that are derived from sand and these cores are wafer-thin. The cores are coated with a blue solution before being exposed to UV light and etched to form a type of circuit. There is also a tiny transistor inside the processor, which acts as a switch to turn it on and off.

A quad-core processor uses more power than a dual-core chip, and your laptop battery supplies this power. When you’re running a quad-core chip, your overall battery life will be lower than if your machine was fitted with a dual-core processor.

Design

Core 7

Quad-core processors are designed to be compact, fast, and easy to change when upgrades are needed. Processors are usually square and made from materials that repel heat to keep the cores cool.

Quad-core processors tend to generate more heat than dual-core chips, as each core emits its own heat. When quad-core processors are fitted, you’ll usually have better cooling fans in the laptop.

A processor doesn’t have to be aesthetically pleasing, as most laptop users will never see the chip. The chip designers constantly update processors to make them faster and to meet the challenges of modern computing.

Price

Because there are more cores, a quad-core processor will usually be more expensive than a dual-core processor. You’ll find that most budget laptops are not fitted with quad-core processors, to keep the prices down.

There are some exceptions, and a dual-core processor with a higher clock speed may be more expensive than a quad-core processor. There are also manufacturers that make custom chips, and these are often costly.

Innovation

Core i7 Ryzen

Both Intel and AMD update their quad-core processors regularly and you’ll see this when you’re looking at specs. Many of the latest processors can now be turbo-boosted to get a higher clock speed.

Manufacturers are also now looking at combining the CPU with the graphics processor in a single chip. This innovation will save a little space, and in time the costs of these all-in-one chips will drop and they’ll be fitted to more machines.

Why They Stand Out

In the majority of cases, a laptop that’s fitted with a quad-core processor will be faster than one with a dual-core chip. Task management will be swift and efficient, and you’ll be able to perform more tasks at the same time.

The general rule is that more cores equals more speed for general computing tasks; so buying a laptop with a quad-core processor is beneficial.

An important thing to bear in mind is that it’s not necessarily how many cores you have, but what software you’re running. For example, Google Chrome automatically tells different cores to run different tasks and a quad-core chip will not give a performance boost.

Laptop

When laptoping.com reviewed the 8th generation Intel quad-core i5-8250U processor, they were impressed with its speed. The processor handles 4k video smoothly, and streaming videos only use five percent of the power.

The reviewer was impressed with how cool the laptop was during the tests with a temperature of over 100 degrees fahrenheit.

The same website also reviewed the AMD A8-7410 quad-core processor and praised its smooth performance. The reviewer was impressed with the low cost of the processor compared to some of its rivals. They also liked the fact that the A8-7410 has an integrated Radeon R5 graphics processor.

Notebookcheck.net looked at the Intel Pentium N3710 quad-core processor, which is designed for entry-level laptops. They said that base speed of the processor is good and suitable for everyday computing tasks. They liked the fact that the processor didn’t use too much power and it stays reasonably cool.

Dual-Core

Dual Core Intel

A dual-core processor looks exactly the same as a quad-core chip but it only has 2 cores.

These processors are more common than quad-core processors at the moment, because of their lower price.

As with quad-core processors, Intel and AMD are the most common chips fitted to laptop computers. Many laptops at the cheaper end of the price scale will be equipped with a dual-core processor.

Dual-core processors still have their place, and it doesn’t mean your laptop is inferior because it doesn’t have a quad-core chip. Many laptop users are quite happy working with dual-core processors for everyday computing tasks.

Components

Dual-core processors are similar in design and construction to quad-core chips, apart from having half the number of cores. The casing and pins are similar, and they’re fitted to the laptop in the same way.

Dual-core processors have the same wafer-thin layers of silicon that quad-core chips have, which are specially treated to turn them into a processor.

Design

Intel i5 and i3

As with all processors, a dual-core is not meant to be seen and they look basic and functional. A heat-resistant housing holds the two cores, and the copper pins are at the base, which connects to the laptop.

Dual-core chips run cooler than quad-core and your laptop will not have to work so hard to stay cool. Your machine will still have a cooling fan, but it probably won’t kick in so often when you’re using dual-core processors.

These two core chips require less power than a quad-core processor, and your laptop battery should last longer than it would with a quad-core chip.

Price

Dual-core processors are generally cheaper than quad-core, and this is one of the reasons they’re fitted to budget laptops. Laptop manufacturers can keep the price of a machine low if it’s not fitted with the latest quad-core processor.

Cheap does not always mean lower quality, and the Intel and AMD dual-core processors have a good track record for outstanding performance. You may not need the extra two cores. If you don’t need them, then money can be saved when buying a laptop.

Innovation

Laptops Dual Core

Both Intel and AMD continue to develop and upgrade their dual-core processors, and they will need to for the foreseeable future. Due to the fact that there are so many of these chips being used, they need to be upgraded from time to time.

As quad-core becomes the norm, it may be the case that dual-core processors will fade away and no longer be used. However, because there is still a demand for budget laptops, this is probably a number of years away from happening.

Why They Stand Out

Dual-core processors have been around for a while and they continue to perform well when fitted to laptops. Most users have no issues with a dual-core chip, reporting that performance and clock speeds are good.

A decent dual-core chip will handle most tasks with speed and efficiency, and the laptop will run smoothly.

One of the main things that make dual-core processors stand out is price, which is important to most consumers. A laptop is a costly piece of kit, and if money can be saved when buying one, it’s always beneficial.
