What happens if you build a PC without a graphics card? A Friendly Guide to Integrated Graphics

Hey there! So you‘re thinking about building a new PC but don‘t want to splurge on a fancy graphics card just yet. Well don‘t worry, you‘ve come to the right place!

As your friend in the world of PC building, I‘m here to guide you through the process of crafting a capable gaming and productivity machine using only integrated graphics.

A Quick 101 on GPUs

Before we dive in, let‘s first demystify some terminology around graphics cards.

There are generally two types of GPUs (graphics processing units) found in desktop PCs:

Discrete GPUs: These are physical cards that slot into PCIe slots on your motherboard. Discrete GPUs like Nvidia‘s RTX cards and AMD‘s Radeon RX cards pack tons of graphics horsepower with their own dedicated video memory and cooling systems.

Integrated GPUs: Also known as iGPUs, these are graphics chips built directly into the CPU die itself. Intel and AMD both offer integrated graphics solutions that share access to your system‘s RAM.

Now as you can imagine, discrete GPUs offer far more graphical processing muscle for gaming, media creation and other intensive workloads. But integrated graphics have evolved to suffice for general home and office tasks.

And the good news? Most modern CPUs from Intel and AMD come with capable integrated graphics that don‘t leave you completely stranded without a dedicated graphics card!

Gaming Without a Graphics Card

Let‘s address the elephant in the room – can you really game without a dedicated GPU?

The short answer is yes…to an extent! You will have to temper your expectations and accept lower resolutions with graphics settings dialed way down.

But plenty of eSports and older titles are very playable on an iGPU. As an example, here‘s a quick look at some average FPS counts in a few popular games running on integrated Vega 8 graphics:

With the right combination of CPU power and fast dual-channel system memory, an iGPU can pump out playable frame rates in esports and older games. You‘ll have to make some sacrifices in resolution and graphic details of course.

But it‘s a great starting point before adding a dedicated GPU! More on that later.

Everyday Computing Without a GPU

Gaming aside, integrated graphics offer plenty of muscle for your daily productivity and entertainment when you don‘t need heavy graphics acceleration.

Basic tasks like web browsing, office applications, media streaming are handled just fine by modern iGPUs. Even photo editing in Lightroom and 1080p video editing in Premiere Pro can provide decent experiences.

To quantify some of this performance, take a look at how Intel‘s Iris Xe and AMD‘s Vega iGPUs stack up against each other in synthetic benchmarks:

As you can see, the Iris Xe and Vega 11 represent the upper tier of integrated graphics performance and will handle most productivity workloads just fine. The key is pairing them with CPUs that have enough multi-core performance.

I‘d recommend at least a 6 core/12 thread CPU, but even budget quad core chips like the Ryzen 3 3200G can deliver smooth everyday experiences with the Vega 8 iGPU. And they leave tons of upgrade headroom later!

Choosing the Right CPU

If you‘re building a PC without a dedicated graphics card, choosing the right CPU deserves careful consideration:

Look for a CPU with the strongest integrated graphics capabilities that fits your budget.

For Intel processors, target CPUs with Iris Xe or UHD 750 graphics. Avoid ones with UHD 730 or lower if possible.

On the AMD side, aim for Ryzen CPUs ending in "G" like the 4600G or 5700G. These pack the latest Vega iGPUs. Ryzen without the "G" rely on discrete graphics.

Also keep an eye out for deals on previous gen APUs like the Ryzen 5 3400G which still offer decent Vega 11 graphics.

Favor CPUs with higher core/thread counts, as iGPUs benefit from additional CPU muscle. Aim for 6-core or 8-core chips when possible for smoother gaming experiences.

Make sure your CPU choice is paired with a motherboard that supports the integrated graphics, either through video outputs or by having video ports on the rear I/O.

Consider overclocking as you can often squeeze extra graphics performance by bumping up the iGPU clock speeds. Just make sure to get a CPU cooler adequate for the increased heat output and power draw.

Boosting iGPU Performance

Beyond choosing the right CPU, there are a few other ways to maximize integrated graphics capabilities:

• Use fast dual channel RAM – Favor 3200MHz+ memory with low CL timings, as iGPUs rely heavily on memory bandwidth

• Get an SSD – Boot from an NVMe SSD to avoid storage bottlenecks and load games/apps faster

• Enable XMP/DOCP – Make sure memory XMP/DOCP profiles are active in BIOS for full RAM speeds

• Overclock the iGPU – Carefully raise iGPU clock speeds for extra performance, if thermals allow

• Update drivers – Download latest GPU drivers from AMD or Intel for best experience

• Tweak in-game settings – Lower resolutions, turn down effects/shadows, increase draw distances etc.

With some performance optimization tweaks, an iGPU can really stretch its legs!

Adding a GPU Later On

The beauty of building a PC without a dedicated GPU is that you can always add one later to transform your gaming and content creation abilities!

Even an entry-level discrete card like the Nvidia GTX 1650 or AMD RX 6400 can enable smooth 60fps gameplay at 1080p on medium settings in most popular titles. And they can often be found for well under $200, making it an easy upgrade.

For example, take a look at how FPS can jump dramatically in some games by adding a budget GTX 1650 to a system previously running on integrated graphics:

For more graphical horsepower, something like an RTX 3060 or RX 6600 XT provides excellent 1080p and respectable 1440p performance in the latest AAA titles.

So you can customize your upgrade path over time as your budget allows. No need to splurge all at once!

Final Thoughts

Building a PC without a dedicated graphics card is totally doable and a great starting point! Modern integrated graphics solutions can genuinely deliver good-enough experiences for many gamers and everyday users.

Pair an iGPU with a decent CPU, fast RAM, and SSD storage for a capable 1080p gaming rig on a budget. Then add in a discrete GPU whenever you‘re ready to take things to the next level.

Hopefully this guide has demystified integrated graphics and given you confidence to start your PC build even without a fancy GPU! Let me know if you have any other questions – I‘m always happy to help a friend navigate the world of PC building.

Game on!
