Intel UHD Graphics 620 Review – All You Need to Know [2023]

In the world of computers, there are consumers of all kinds. Some are happy with their basic functioning systems, some are highly demanding in what they are being offered, some are super-specific, and so on. The varying range of the kinds of users is vastly broad. That is why manufacturing companies find themselves constantly developing, changing, and switching things up to meet the demands of people.

In the last few decades, computers have been perceived as the most life-altering and successful invention that is working out problems in human life. There is not a single business today that doesn’t find itself lending the help of technology in one way or the other. In the educational sector, for once, health, transport, and mainly the communication area, you can see the impact and application of computers. It’s tough to hold a business without embracing computers.

What we aim to do is dig deeper into the aspects that are of the utmost significance but we seldom find ourselves falling into any detailed conversations of a laptop or computer’s build, core, what graphics card it uses, its compatibility, RAM discussions and much more. 

Graphics Card 

Before we dive into the details of UHD Graphics-620, it is imperative to fully grasp the concept of it all. A graphics card sounds fancy, doesn’t it? But what it actually is just computer hardware that is responsible for producing the image and visuals you see on your monitor or laptop screen.

The pictures you see on your monitor are composed of small dots called pixels. At broadly common settings of the resolution, a screen displays more than a million pixels, and the computer determines what to do with them all in order to generate an image. To be able to do this, it requires a translator, something that can take binary data from the CPU and turn it into a picture that can be seen clearly. But if a computer already has graphics ability manufactured into its motherboard that translation can be done by a graphics card.

A graphics card’s task is complicated, but its principles and elements are simple to understand.  For example, let’s suppose there’s a company with its own art department and in-house artists, when an artwork is required the company sends the request to the department and their artists decide what to do and how best to do it, turning their ideas into an actual visual. The graphic card works in a very similar pattern. The CPU collaborates with software applications to refer information regarding the image to the graphics card which in turn decides how to use and manipulate the pixels on the screen to create an image. And that information is then sent to the monitor.

This process takes place using these four components:

  • Motherboard connection.
  • A processor that instructs what to do with each pixel.
  • Memory to handle information about every pixel.
  • A monitor connection to witness the final output

After this, the next crucial aspect to learn is about the types of graphic cards, there has always been an enquiry on what approach to take with these cards. Use an inbuilt one or spend some coin for a standalone. 

The two types of these cards are

This card is the one where the CPU and the GPU (graphics processing unit) are on the same chip, hence the name integrated. This means this card uses the system RAM (memory) and system CPU, if your computer’s RAM is 8GB, the integrated graphics card will use half of it. This ultimately means that not all of these components can work at their maximum capacity as they share space and memory.

Banking on the size of the task, your graphics card will usually expend between one and five percent of the accessible memory for graphics processing in gaming or simple multitasking.


  • It comes with the CPU so no extra expenditure
  • No worrying about the installation of the GPU
  • No separate heat concerns
  • Forget the hassle of checking compatibility
  • Increases battery life.


  • Slow
  • Not much for gaming
  • Lack of RAM
  • Not good enough graphics 


It is a separate system that uses its own independent source of memory and processor. It provides the CPU with a breather from all the graphics work which results in efficient and fast workflow. It is like a mini-processor that is wholly dedicated to rendering the visuals. It comes with automatic updates and flexible choices of picking different models with faster GPU.


  • More memory 
  • Perfect for hardcore gaming
  • Great graphics 
  • Faster CPU
  • Separate motherboard
  • More features
  • Overall improved performance 


  • Heat issues
  • Extra cost
  • Compatibility problems
  • More power consumption 

So, which one to pick?

Integrated is more affordable and is able to render the basic graphics and you can also play games with it but you would need to set the resolution on the lower side. Dedicated, however, in contrast, is a bit heavy on the wallet but is a nice investment. It not only delivers epic graphics but also speeds up the workflow of your system in general to make everything a smoother experience. Although the question is how much power you require from your card and based on all the pros and cons you can make your decision. 

UHD Graphics 620

Now that we have broken down all the details of graphics cards, their purpose, and importance, we now come to UHD Graphics-620. UHD stands for ultra-high definition and is a direct successor of HD or high definition and has four times better resolution. It is an integrated graphics unit that can be commonly found in the various ultra low voltage processors of the Kaby Lake generation which is the eight generation Core of Intel. Seeing as how it is integrated, you will be able to understand much better what it entails and offers. 

The details and workings of a graphics card have been explained above but now we look at the in-depth description of UHD Graphics 620.

The Intel UHD 620 Graphics is used in the broadly accepted 8th Generation Intel Core U-series laptop processors. It is almost similar to the previous HD 620 of the 7th Generation Core. The new version has only a little bit of amplified clock speed as the key distinction. Both of these rudimentary integrated graphics processors are adequate for some basic level, casual gaming and multimedia use.

However, some tests of the UHD 620 integrated into the popular 8th Gen Intel Core i5-8250U quad-core processor demonstrated some evident performance developments in some games when described in relation to previous tests of the i5-7200U dual-core / HD 620. Specifically, in games like Grand Theft Auto 5, and FIFA 2018. These refinements are an outcome of the faster execution of the 8th Generation Core CPUs, to speak so generally, and other components that include faster RAM, extra optimized software, and drivers than the speed of the graphics processor.

Here are some of the technical specs of UHD 620

  • Number of Execution Units, Cores, Shaders:24
  • Video Memory Size: Shared main memory and depends on the system
  • Memory type: Shared with system memory
  • Video Memory Speed: Dependent on system memory 
  • ROPs / TMUs :8 / 16
  • Core Clock Speed: 300 – 1,100 MHz on i5 CPUs / 300 – 1,150 MHz on i7 CPUs
  • Memory Bus Width: 128-bit 64-bit
  • Resolution :4096 x 2304
  • Processing Power:422.4 − 441.6 GFLOPS
  • Base Frequency : 300 MHzMax Frequency1.10 GHz / 1.15 GHz
  • 4k Support: Supported at 60HzMax 
  • Production Technology:14-nanometer

This Graphics Processing Unit is incorporated with Intel’s 8th generation processors. It is established on the Kaby Lake Refresh structure. Correlated with earlier generations, this brings forth some new features like 10-bit colors, H.265/HEVC Main 10 Profile, and HDCP 2.2. The Thermal Design Power (TDP) is identical to 15W which is the same as the processor. It is founded on the 14nm Tri-Gate (FinFET) production system.

It can boost a maximum VRAM/Graphics Memory of 32 GB and the memory type will be dependent on the RAM. The base frequency of this GPU is 300 MHz which is the same as the prior generation HD 620 graphics. Nonetheless, the all-out GPU frequency is greater than HD 620 and it is 1.10 or 1.15 GHz. So in this scenario of Core-i5, the maximum frequency is 1.10 GHz and for Core-i7 it is equivalent to 1.15 GHz. 

It does support 4K at 60Hz and the peak display resolution can be 4096 x 2304 pixels. At the same time, you can easily connect a maximum of three displays with this graphics processor. Most of the features are pretty much the same as the earlier generation but there are some slight improvements in some regards for sure.


The precise performance of the UHD Graphics 620 relies on several factors like cache size, memory, and the maximum clock rate of the particular model; it is similar to the Intel HD Graphics 620 and Intel HD Graphics 630. Described in relation to the average HD Graphics 620, the UHD graphics revenues from the quad-core CPU and then some in the gaming standards. For games, the drivers are not so quickly updated and assessed as with some graphics cards. UHD 620 has tested out to be the most competent for simple games.

Apart from some serious 3D rendering, integrated graphics solutions in the processor have enough power and capacities to ace most of everyday tasks. Since there is an affiliated graphics processor in every Intel CPU, the graphics chips are normally among the best-selling explanations.

Some of the features of UHD-620 are:

  • Improved support for three independent display options
  • Timely synchronization of video
  • Clear graphics 
  • Cleaner video
  • Basic Gaming
  • High definition multimedia
  • Enhanced clock speed
  • 4K support


Being an integrated graphics card, as we have established already, UHD Graphics 620 doesn’t possess any memory of its own. It utilizes the system’s memory (RAM) as its video memory. That means it will always share the memory with the CPU. This will cause the CPU to spare substantial size of its RAM for the graphical rendering part of the process. The maximum memory it can support is 32GB and it will invariably be less than the RAM, making it insufficient. 

It has a clock speed of 1.150 MHz and thus 100 MHz higher than the old HD Graphics 620 ( which at most offered 1.050 MHz) and gives a comparative performance. Due to its scarcity of dedicated graphics memory or eDRAM cache, the HD 620 has to take from the main memory because there is no other option.

Although a dedicated graphics card can be a yearning for those interested in high-quality graphics, integrated graphics like UHD 620 are not half as bad. They simply make you compromise a little on the visual quality as far as gaming is concerned but the general multimedia options like videos and stuff are of decent enough quality. And not only that, you can easily have good quality video edits through UHD-620, too. It tends to take time and use a lot of memory but it definitely gets the job done.

Here are some pros and cons of UHD-620


  • Less power consumption 
  • Less heat emission
  • Good for Photoshop and video editing 
  • No extra cost for a graphics card
  • Easy compatibility 
  • No installations required
  • Comes with the CPU
  • Suitable best for simple browsing and watching movies


  • Low performance 
  • Mid-range graphics while gaming
  • Some users experience lag
  • Shares memory with the system

Many users have different opinions with regards to this graphics card and what it can provide for the gaming world. It is important to note that for a gamer, good and clear visuals are of the utmost importance. Gamers are wholly dedicated to this art and take their processors and graphical features very seriously. 

While many love to sit and play games, some of them can’t exactly afford all the fancy things and so this is where UHD 620 comes into play. Although it has its drawbacks and shortcomings particularly for gaming, it does work. Not everyone can go and splurge on a dedicated graphics card and call it a day. With a little bit of compromise on the visual quality, you can most definitely enjoy some of the best indie games if not the grand ones.

Being a mid-range graphics card, UHD Graphics 620 works relatively well for gaming. This does not imply that you can expect outstanding performance when it gets to modern games but consider it as average, acceptable, and reasonable. Contrary to dedicated video cards, UHD Graphics 620 eats up less power, generates less heat, and is rooted in the 8th generation Intel Core U processor. It all also depends on the type of games you want to play.

Here are a few examples of some of the games that play well on UHD 620.

League of Legends on full HD resolution between sixty to eighty frames per second delivers a smooth experience. GTA 5 is another common favorite that saw definite improvement compared to HD-620. Though it is a demanding game, with low resolution and settings, it can be a good time. The same goes for FIFA 2018, by turning the HD settings down and the resolution, it can end up being a happy experience. This, too, however, sees a reasonable improvement from HD-620. Fortnite Battle Royale is a big hit among gamers and this game set to low HD settings and resolution can easily be played on this processing unit. It’s still playable on medium settings but delivers a rather lagging and choppy output. Some of the other smoothly playable games are Dead Cells, StarCraft 2, Return of the Obra Dinn.

How to Improve the Gaming Experience 

While the whole gaming aspect can be a bit of a letdown, worry not for we have a few tips and tricks. Integrated graphics have expanded over the past years, but they still aren’t as swift as dedicated graphics hardware.  Here’s how to pinch some more gaming performance out of your UHD Graphics 620 

Update: Updating your graphics driver will drastically make some quick improvements.

Adjust Performance Settings:  In the graphics control panel, you can switch up your performance.

Allocate more memory: Dedicating more system memory to your ongoing graphics will improve the overall performance

Modify game settings:  This is a very important way to have your games perform better. Turn down your graphics settings in games to have a smoother experience 


Henceforth, there isn’t much that can be done to magically enhance the performance of your UHD Graphics 620, however, for an integrated graphics card, it works really well. Getting the most out of your graphics unit requires a few tweaks and adjustments but for the basic everyday tasks and for even enjoying Netflix or some multimedia, it is the correct option. While it can be tempting to want to get a dedicated graphics card, make sure that your needs actually require one otherwise an integrated card like UHD-620 is the best option.
