Processor: Core i7-6500U
Display: 15.6 Inches
Battery: 1 Lithium-ion battery
Ram: 8 GB DDR3
Hard Disk: 1TB HDD

1. Performance

This 6th generation Core i7 can provide excellent performance with a CPU that has a base clock speed of 2.5 gigahertz with a turbo boost up to 3.1 gigahertz. This means it could dynamically increase and decrease depending on the task you’re doing.  This is one of the better processors you can get in this price range, and it can provide sufficient power for office multimedia purposes. It can also handle high demand software and multitasking without any problem.

This laptop offers moderate to heavy multi-tasking capabilities with its 8 gigabytes of DDR3L RAM. This amount of RAM can help you run a fair amount of programs in the background without worrying about getting a sluggish performance.  It is typical in this price range and good enough for most users.


2. Design 

The design of the Dell Inspiron i5559 is elegant and refined. The interior of this laptop has a matte grey finish, whereas the exterior is encased in a silver finished shell that both feels and looks premium. It features much more toned down elements, slightly rounded edges, and a discrete trackpad/keyboard combo. All these elements help to make the user experience more pleasant.


3. Display

The screen features a full high-definition 1080p Led-backlit display along with anti-glare coating finishing so that users will be able to use their laptops in outdoor environments or places with high light. Plus, the 1920*1080p resolution FHD display comes in handy when playing videos.

The one feature that makes it special is Intel’s new and exciting proprietary RealSense technology that significantly improves user’s input by introducing gesture control, just as it is done on our smartphones.


4. Processor 

The Dell Inspiron i5559-7080SLV is powered by the Intel Core i7-6500U processor. This Core i7 processor comes from Intel’s U series. It is designed to function at a low power setting and has a thermal design power of just 15 Watts, which makes it ideal for mobile devices craving for battery life. The Intel Core i7-6500U processor has a total of 4 MB of Intel’s own proprietary Smart Cache as well as a maximum turbo boost frequency of 3.10 GHz. This processor also features its own Intel HD 520 integrated graphics card.

The primary benefit of this feature is that technologically proficient users will be able to enter the laptop’s BIOS and disable the discrete AMD Radeon graphics card and switch on the Intel HD 520 integrated graphics card, which will further improve the battery power consumption of the laptop and significantly extend its operating time.


5. System Memory

The laptop features two low power consuming 4 GB sticks of DDR3L SDRAM. The motherboard of the laptop, however, is capable of supporting a maximum system RAM of 16 GB. If you want a smoother operation, you can swap out the 4 GB RAM sticks with 8 GB RAM sticks at the time of purchase. This will also future-proof the purchase as much as possible.

At this price point, laptop manufacturers typically tend to design their products with the latest DDR4 SDRAM to take the full benefit of the latest RAM data transfer speed. Nevertheless, it is not far-fetched to guess that Dell probably didn’t go that way because it wanted to keep the price of the laptop below $1000.


5. Graphics Card

The Dell i5559-7080SLV features an entry-level GPU or graphics processing unit by Dell. The AMD Radeon R5 M335 discrete GPU is furnished with 320 processors, a clock speed of 1 GHz as well as a VRAM of 4 GB.  All these features sound startling on paper but don’t get your hopes high just yet. They are worthless when translated into real-world performance figures. It won’t be able to handle the newest titles unless their settings are dialed down to low. You can also find the benchmarks with just the tiniest amount of effort on Google search.


6. Keyboard

The Inspiron i5559-7080SLV comes with a backlit laptop that allows you to keep going even when it is dark, providing better typing accuracy in low light. The keyboard also comes with a 10-digit numeric keypad that helps you navigate spreadsheets or crunch numbers. There is also a large precision touchpad for your convenience.


7. Battery life

Provided data of the battery performance on the official website of the laptop is not the ultimate result because the official test is not likely to include the various factors of a real-world setting, mostly where the users will operate the laptop. That’s why, with its discrete graphics card, the Dell Inspiron i5559-7080SLV is unlikely to be a power-saving laptop.


8. Storage

This laptop has 1 TB of abundant storage space. The average diligent users shouldn’t need to delete any data in order to have free space. However, the performance of the laptop could have been better if only the manufacturer had replaced the mechanical one terabyte drive with a solid-state drive of 512 GB or 256 GB, which already exist at this price range from laptop brands, such as ACER or ASUS.


9. Portability 

At 5.4 pounds, it is a bit heavy laptop. Carrying it around will not be quite easy for everyone. It is just too bulky to be a portable device. Therefore, it will be better suited as a desktop replacement laptop.



This laptop will cost you around $600, which is not bad at all with all the features it is offering. It is a good pick at this price point.



  • 6th generation Intel processor
  • Intel RealSense Technology
  • Adequate storage space and system memory 
  • Fine High Definition display
  • Dedicated video card
  • Good battery life


  • A bit on the heavy side
  • No SSD

Should you buy it?

This depends on what you are looking to get out of your laptop. If you are looking for a laptop with a high-end configuration that will help you run all the latest software, then this will not be a good choice.

However, if you are a moderate daily user, then you can go for it. While making this as your final choice, you should also remember that it is a bulky laptop. It might not be what you are looking for if you want to take your device wherever you go.


Final Thoughts

The Dell Inspiron 15 i5559-7080SLV comes with a good configuration. It is a fine but slightly pricier and heavier laptop.
