Many users, faced with graphical glitches or the need for an upgrade, wonder about the physical location of the GPU. Unlike RAM or storage, finding a video chip on a laptop board without special knowledge is quite difficult. This is a tiny chip that is the heart of the graphics processing system.
Understanding where the video chip is located is critical when diagnosing overheating or the need to resolder. In modern devices, the architecture can be radically different: from microcircuits integrated into the processor to separate expansion cards. Let's look at the main placement scenarios.
Integrated graphics: where to look for a chip in modern laptops
In the vast majority of modern ultrabooks and office models you will not find a separate video controller chip. Such devices use integrated graphics, which is part of the central processing unit. This means that the video core is physically located inside the same case as CPU.
If you open the lid of your laptop and see a large square chip with a heatsink, most likely there is both a processor and video chip hidden under it. It is physically impossible to separate them without completely dismantling the crystal, which is equivalent to replacing the entire processor. Such solutions save space and reduce power consumption, but limit performance in heavy tasks.
To check the presence of such a configuration, just go to Device Manager on Windows. In the "Video Adapters" section you will see the name Intel HD Graphics, UHD or Iris Xe. This confirms that the graphics core is integrated with the central processor.
Discrete graphics: location of a separate video chip
Used in gaming and workstations discrete video card. Here the situation is different: the video chip is a separate chip soldered to the motherboard. It is usually located some distance from the processor, often at the other end of the board or in a special recess.
This chip is usually larger than the northbridge (if there is one), and it has its own separate heatsink with heat pipes. Next to the video chip you will see RAM chips (VRAM). The presence of several memory chips will directly indicate that you have found a discrete video processor.
The specific location depends on the manufacturer. U NVIDIA chips are often square in shape and have black markings, while AMD they may be slightly smaller and have different markings. It is important to distinguish the GPU itself from the memory chips that surround it.
It is important to understand that some thin gaming models use technology MXM, where the video card is a module, but this is rare in the mass segment. In 95% of cases the chip is soldered to the board.
⚠️ Attention! Do not attempt to separate the video chip from the board yourself unless you have experience with soldering equipment. The risk of the contact pads (BGA) coming off is extremely high, which will lead to failure of the motherboard.

Visual identification of the chip on the motherboard
If you are planning a repair or replacement of thermal paste, you need to be able to visually distinguish the video chip from other components. On the board it is usually marked with the manufacturer’s logo: NVIDIA, AMD or Intel. Chips from NVIDIA series GeForce RTX often have large inscriptions on the chip body.
Pay attention to the cooling system. The video chip is always covered with a metal heatsink. To see the crystal itself, you need to carefully remove the radiator, first unscrewing the fasteners and cleaning the old thermal paste. This must be done extremely carefully so as not to damage adjacent small components.
Chip shape may vary. Modern GPUs are often shaped like a square or rectangle with many small pins underneath (BGA technology). Next to it you will definitely see memory chips arranged in a checkerboard pattern.
If you see the inscription GDDR6 on the chips around the main square, you've definitely found the GPU. This is a type of memory used exclusively for video cards.
Software methods for determining type and location
Before disassembling your laptop, you should use software tools to accurately determine the configuration. This will help you understand whether you have a discrete card, and whether you even need to look for a separate chip. Use the utility GPU-Z, which will show detailed information about the video subsystem.
In the program you will see the “Bus Interface” field. If it is indicated there PCI Express x16 or x8, this means that the chip is connected to the bus and is a separate device. If you see Integrated or Shared Memory, which means the chip is inside the processor.
You can also use the command line. Enter the command

Layout features in different classes of devices
The location of the video chip greatly depends on the class of the laptop. In budget models and netbooks you will only find integrated graphics, which is located under the same heatsink with the processor. This simplifies the design, but makes it impossible to upgrade the graphics.
In mid-range gaming models, the chip is often located next to the processor, but under a separate heatsink. In such cases, the cooling system usually has a complex configuration with two fans and common heat pipes covering both chips.
In professional laptops for rendering and 3D modeling, the video chip can occupy a significant area and have its own powerful cooling system. Sometimes it is even placed on a separate substrate for better heat dissipation.
Why does the video chip get hotter than the processor?|GPUs under full load generate a huge amount of heat due to the high computing density. Unlike a CPU, which has a complex architecture with a cache, a GPU consists of thousands of simple cores running simultaneously. This leads to intense heat generation, requiring more efficient cooling systems and high-quality thermal paste.-->
Typical problems and troubleshooting
The most common problem associated with the video chip is its overheating and subsequent failure from the board. Due to the constant expansion and contraction caused by heat, the solder joint under the chip (BGA solder) can crack. This manifests itself in the form of artifacts on the screen or complete loss of the image.
If you suspect a problem, pay attention to the laptop's boot behavior. If the image appears but then disappears, or color streaks appear, this may indicate a problem with the video chip or memory. Diagnostics requires connecting an external monitor via HDMI or DisplayPort.
Sometimes the problem lies not in the chip itself, but in the power circuit. Checking the voltage on the video chip power lines with a multimeter may show an open or short circuit. This requires deep knowledge of circuit design.
Below is a table comparing the characteristics of the chip layout in different architectures
HDMI or DisplayPort.| Architecture type | Physical location | Possibility of replacement | Temperature |
|---|---|---|---|
| Integrated (Intel UHD) | Inside the CPU case | CPU replacement only | Low |
| Discrete (NVIDIA GeForce) | Separate chip on board | Repair by soldering or replacement | High |
| Discrete (AMD Radeon) | Single chip or module | Repair by soldering | Medium/High |
| Mobile station (MXM) | Removable module | Easy replacement | Very tall |
⚠️ Attention! When replacing thermal paste on a video chip, use only specialized materials with high thermal conductivity. Regular processor paste may not cope with the load and dry out quickly.
Precautions when working with video chip
Working with a graphics processor requires strict adherence to safety precautions. Microcircuits are very sensitive to static electricity. Before touching the board, be sure to ground yourself using an antistatic wrist strap or by touching the metal case of the system unit.
Use the correct tool to remove the radiator screws. Screws often have a specific shape (Torx or Phillips) and can be tightened with greater force. Do not use excessive force to avoid stripping the threads or damaging the chip itself.
If you are planning on resoldering a chip, remember that this is a high temperature process. Using a soldering gun requires precise adjustment of temperature and air flow. Incorrect actions can lead to degradation of adjacent elements or peeling of tracks.
The video chip in a modern laptop is either part of the processor or a separate BGA chip under the heatsink. For diagnostics and repairs, it is critical to accurately determine the type of architecture before starting any manipulations.
⚠️ Attention! Do not use a household hair dryer to dry or heat the chip. This will lead to local overheating and irreversible damage to the crystal. Use only professional soldering equipment.
Prospects for the development and replacement of the video subsystem
Laptop manufacturers strive to integrate components as much as possible to reduce size. This makes replacing the video chip almost impossible for the average user. In the future, we'll likely see even greater integration, where graphics will be part of a single SoC chip.
However, there are external video solutions (eGPUs) available for enthusiasts. They connect via port Thunderbolt or USB4 and allow the use of powerful desktop video cards. This is a great way to get around the limitations of integrated graphics without disassembling your laptop.
When choosing a laptop, it is important to consider not only the processor model, but also the presence of a discrete card. If you plan to play games or work with graphics, look for models where the chip is located separately and has a powerful cooling system.
Frequently asked questions from users
Is it possible to replace the video chip with a more powerful one in a laptop?
In most cases this is not possible since the chip is soldered to the motherboard and has a unique layout. The exception is rare models with an MXM connector, but they are extremely rare and expensive.
How to distinguish a memory chip from the video chip itself?
The video chip is usually larger and is marked by the manufacturer (NVIDIA, AMD). The memory chips are smaller, located around the main chip, and labeled as GDDR5, GDDR6 or HBM.
What to do if the laptop stops turning on after replacing the thermal paste?
You probably damaged the contacts when removing the radiator or did not press the radiator tightly. Check the integrity of the board and make sure the screws are tightened evenly diagonally.
Why does the video chip get hot even if I do nothing?
This could be a sign of a miner virus or a driver error that does not put the card into power-saving mode. Check processes in task manager and update drivers.
