Integrated graphics is a graphics processor built into the CPU package, so the processor can draw images on a monitor without a separate graphics card. For a gaming PC it matters in two ways: it is a handy backup display output when a discrete card fails, and on some chips it is good enough for light games, though it is not a replacement for a dedicated GPU.
What integrated graphics means
A graphics card (discrete GPU) is a separate board with its own processor and dedicated video memory. Integrated graphics, often shortened to iGPU, is a smaller graphics engine placed on the same chip package as the CPU cores. It does not have its own memory modules. Instead it borrows a slice of your system RAM, which is why memory speed and dual-channel configuration affect it far more than they affect a discrete card.

View on AmazonThe iGPU connects to the video outputs on the motherboard’s rear panel (HDMI or DisplayPort). A discrete card connects to its own ports on the back of the card. Mixing them up is one of the most common reasons for a “no signal” problem on a new build.
Which current processors include it
- AMD Ryzen 9000 and 7000 desktop chips: sources report these include a basic iGPU with two RDNA 2 compute units. It is designed for display output, troubleshooting and video playback rather than gaming. Reviewers describe it as supporting several displays and hardware decoding for common video formats such as AV1, HEVC and H.264.
- AMD Ryzen “G” chips: models in the G-series use a larger integrated graphics engine and are the ones meant for budget gaming without a graphics card.
- Intel Core Ultra 200S and earlier Core chips: most standard models include Intel integrated graphics. Models with an F suffix are sold with the graphics disabled, so they need a graphics card to show anything on screen.
The exact graphics configuration varies by model, so the processor maker’s product page is the reliable place to see whether a specific chip has an iGPU and how large it is.
How it differs from a discrete graphics card
| Aspect | Integrated graphics | Discrete graphics card |
|---|---|---|
| Location | Inside the CPU package | Separate card in a PCIe slot |
| Memory | Shares system RAM | Own dedicated video memory |
| Power and heat | Small addition to CPU power | Often the largest power draw in the PC |
| Gaming ability | Basic on most chips; modest on G-series | Wide range, up to RTX 50-series and Radeon RX 9000 class |
| Video outputs | Motherboard rear panel | Ports on the card |
| Main use case | Display, troubleshooting, light use | Games, rendering, AI workloads |
Why it matters for gaming PCs
A free diagnostic tool
If your PC will not show an image, plugging the monitor into the motherboard output lets you tell a dead graphics card from other faults. If the screen works from the motherboard port, the CPU, memory and board are at least partly alive and the card or its power cable becomes the suspect.
A temporary or secondary display
While a graphics card is being replaced or sent for repair, the iGPU can keep the machine usable for browsing and office work. Some builders also use it to drive a secondary monitor so the main GPU stays free for the game.
Video features
The iGPU often includes a hardware video engine. Some streaming and capture software can use it for encoding, which shifts a small amount of work away from the main graphics card. The benefit depends on the software and the chip.
Entry-level gaming
Basic iGPUs handle older titles, esports games at low settings and indie games. For current demanding games, reviewers consistently point to a discrete card.
How to check or set it on your own system
Check whether your CPU has one
- Note the exact processor name in Windows under Settings, System, About.
- Look it up on the maker’s product page and find the graphics section.
- Open Task Manager, go to the Performance tab, and look for a GPU entry labeled with the processor’s graphics name alongside any discrete card.
Enable it in the BIOS when a graphics card is installed
Some boards turn off the iGPU automatically when a discrete card is detected. The setting name and menu path depend on the board maker, so read the motherboard manual. Commonly used names include “iGPU Multi-Monitor”, “IGD Multi-Monitor” and “Internal Graphics”, and on AM5 boards options such as “Integrated Graphics” and the primary video device. Typical steps:
- Shut down and unplug the PC before touching any cables inside the case.
- Restart and enter the BIOS (usually with the Delete or F2 key).
- Find the integrated graphics option in the advanced menus and set it to enabled.
- Save and exit, then connect a monitor to the motherboard output.
Changing BIOS options can affect stability and may matter for warranty terms, so change one setting at a time and note the original value. If the system fails to start, clear the CMOS following your motherboard manual, or contact the board maker.
Common misconceptions
“Integrated graphics is the same as no graphics”
It is a real graphics processor. It simply has far less performance than a mid-range or high-end card.
“Using the iGPU and a graphics card together doubles performance”
Most games do not combine the two. Games use whichever GPU Windows or the application selects, normally the discrete card.
“The iGPU wastes power when I have a graphics card”
When idle it uses very little. Disabling it gives no meaningful benefit on a desktop, according to several guides, and you lose a useful backup output.
“More RAM means a faster iGPU”
Capacity helps only up to a point. Memory speed, dual-channel operation and the iGPU’s own size matter more. Running a single stick of memory commonly cuts iGPU performance noticeably.
When to care and when to ignore it
| Situation | Should you care? | Why |
|---|---|---|
| Building with a dedicated GPU | Minor | Useful backup output, not a performance factor |
| Choosing between an F-suffix Intel chip and a standard one | Yes | The F model has no display output without a graphics card |
| Building a no-GPU budget PC | Yes | Pick a chip with the strongest iGPU you can, and use dual-channel memory |
| Diagnosing a black screen | Yes | Helps isolate a faulty graphics card |
| Playing demanding new games | No | You need a discrete card |
Frequently Asked Questions
Can I play games on integrated graphics?
Yes, but expectations should be modest. Basic iGPUs suit older and lightweight games at low settings, while G-series Ryzen chips and newer Intel graphics do better. Demanding recent titles need a discrete graphics card.
Why does my monitor show nothing when plugged into the motherboard?
Either your CPU has no integrated graphics (such as an Intel F model), or the BIOS has disabled the iGPU because a graphics card is installed. Check the processor’s spec page and the motherboard manual for the relevant BIOS setting.
Should I plug my monitor into the motherboard or the graphics card?
Use the graphics card’s ports for gaming. If you plug into the motherboard while a card is installed, games usually still run on the card in some setups, but the display path can add overhead or restrict features, so the card output is the normal choice.
Does the iGPU affect CPU temperatures?
Slightly under graphics load, because both share the same package. At idle, with a discrete card doing the work, the effect is negligible.
Is an F-series Intel CPU a bad idea?
Not necessarily. If you always use a graphics card, the lack of an iGPU rarely matters. You lose the backup display output, which can make troubleshooting harder.
Does the iGPU help with streaming?
It can, if your streaming or editing software supports its video engine. Support varies by program and processor, so read the software’s documentation.
