Is it better to not have integrated graphics?

Hey friend! Let‘s dive into the age old tech debate between integrated vs dedicated graphics. I‘ll explain what integrated graphics are, when they‘re sufficient, and when you‘re better off with a dedicated GPU.

What are integrated graphics?

Integrated graphics processors (or iGPUs) combine basic graphical capabilities into the CPU itself. Modern CPUs from Intel and AMD allocate part of the chip to non-compute graphical tasks.

Instead of a separate GPU chip, an area of the CPU with its own cores and cache acts as a mini graphical processor. This saves space and cost compared to adding a dedicated graphics card.

Integrated graphics share system resources like CPU cores and RAM with the rest of the processor. This allows basic graphics and video processing without a dedicated GPU, ideal for laptops and budget systems.

But this consolidation means integrated graphics have much less raw power than even entry-level discrete GPUs. There are tradeoffs either way!

Key advantage: Power efficiency

For laptops and mobile devices, the efficiency of integrated graphics is a godsend. Utilizing shared CPU resources means integrated graphics use way less power than even a low-end mobile GPU.

This provides better battery life compared to constantly running a power-hungry Nvidia or AMD mobile GPU. For gaming laptops the dedicated GPU can be disabled when not needed.

But for general use laptops, especially ultrabooks and MacBooks, the meager power draw of integrated graphics is crucial for mobility.

Even in desktops, integrated solutions use much less electricity than most add-in graphics cards. My AMD Ryzen 5600G system with Radeon Vega 7 integrated graphics maxes out around 65W total power consumption under load.

Whereas a dedicated GTX 1660 Super GPU alone can draw 120W+ easy. So there are definite efficiency benefits to relying on your CPU‘s integrated graphics capabilities in some cases.

Key disadvantage: Graphics performance

But how does performance compare? Well I ran some benchmarks on my Ryzen 5600G rig to find out.

In the 3DMark Time Spy test, my Vega 7 iGPU scored just 2358 points. That‘s less than 1/10th the score of a budget GTX 1650 dedicated GPU!

And in Horizon Zero Dawn at 1080p low settings, I averaged a measly 24fps render time on the iGPU. That‘s far from an ideal smooth gaming experience.

Of course FPS and benchmarks don‘t tell the whole story. But there is a very noticeable difference trying to play modern 3D games on an integrated chip versus dedicated GPU.

For example, my Ryzen iGPU struggles to maintain 30fps in Fortnite unless I drop resolution to 900p with minimal settings. That‘s despite the 5600G being a very strong and modern integrated solution!

Dedicated GPUs have vastly more raw processing power and memory bandwidth optimized for graphical workloads. An entry-level GTX 1650 can easily hit 60fps+ even in many new AAA game titles.

So while integrated graphics have come a long way, a discrete GPU is still miles ahead for gaming and GPU compute tasks.

When integrated graphics are sufficient

Now just because integrated graphics can‘t run Crysis doesn‘t make them useless. Let‘s talk about some situations where an iGPU gets the job done just fine!

For general home and office use, integrated solutions work great. Web browsing, watching 4K video, Microsoft Office, and 2D applications pose no problem.

Casual and older games are also fair game for modern integrated graphics. 2D indie games, emulators, RTS titles, MOBAs, and eSports games like Valorant often run 60fps+ on an iGPU.

I had no issues running Apex Legends on my Ryzen Vega iGPU at 60fps on low settings at 900p resolution.

AAA single player experiences at high fidelity are really the only major limitation. For kids and casual gamers, an iGPU allows decent gaming without a dedicated GPU‘s cost.

Video playback is another integrated graphics strong suit. Intel and AMD iGPUs have full hardware decode support for popular 4K formats. My Ryzen chip handles 4K YouTube and even 8K HEVC sample footage without breaking a sweat.

Basic photo and video editing is also viable on a modern iGPU. Simple timeline editing in 1080p won‘t require a powerful discrete GPU. Just don‘t expect to be rendering tons of complex effects and timelines.

Finally, integrated graphics work great for multi-display productivity setups. Both Intel and AMD‘s iGPUs can handle 3-4 monitors for office workflows.

But each display will be limited to the ports and refresh rates supported by the iGPU. Don‘t expect to game or do GPU-intensive work across multiple monitors from an integrated chip.

When to opt for a dedicated GPU

Alright, now that we‘ve covered integrated graphics strengths, let‘s talk about where a dedicated GPU is the better choice.

For any gaming beyond basic eSports titles, a discrete GPU is recommended. Especially at resolutions above 1080p or maxed graphics settings.

AAA games continue to become more demanding each year. A mid-range or better GPU often provides a vastly smoother experience in the latest releases.

For example, in Horizon Zero Dawn at 1080p high settings, a GTX 1060 delivered 56fps to my iGPU‘s unplayable 24fps. That‘s the difference a mainstream $200 GPU makes!

Graphical workstation uses also demand discrete graphics power. Tasks like 3D rendering, CAD, video production, programming, and GPU compute all benefit from stronger dedicated hardware.

Applications like Blender, Premiere Pro, AutoCAD, Unity, Unreal Engine, MATLAB, and more thrive with the horsepower of a dedicated Nvidia Quadro or AMD Radeon Pro card.

Also consider a dedicated GPU if you want to maximize refresh rates above 60Hz for a high FPS competitive gaming setup.

And graphics intensive multiplayer games like Battlefield, Warzone, and Escape from Tarkov perform far better with a discrete card.

For PC VR and AR headsets, an Nvidia 1060/1660 or AMD RX 580 and above card is recommended at minimum for passable fidelity and frame rates.

Finally, having a dedicated GPU is useful as a backup in case you ever need to troubleshoot a failed integrated GPU or driver issues that prevent video output.

So in summary, opt for a dedicated GPU if you plan to play modern games above 1080p resolution, run intensive creative applications, or need maximum FPS for competitive gaming.

Comparing integrated vs dedicated GPU specs

Let‘s compare the raw specs of some integrated vs dedicated options to showcase just how vast the performance differences can be:

Specification	Intel UHD 730 (integrated)	Nvidia RTX 3060 (dedicated)
GPU cores	32	3584
Boost clock	1.1GHz	1.78 GHz
Memory bandwidth	47GB/s	360GB/s
TDP	15W (shared)	170W
Relative performance	1x	Up to 100x+ faster

As you can see, even a mid-range modern discrete GPU vastly outclasses integrated graphics in nearly every regard. More cores, higher clocks, tons more memory bandwidth, and 5-100x more overall performance.

The cost is that big discrete GPUs use over 10x more power and require hefty cooling solutions. But for maximizing FPS, resolution, graphics fidelity, and GPU accelerated workflows, a dedicated card remains the only option.

Let‘s compare some real world game FPS between the cards:

Game	Intel UHD 730	Nvidia RTX 3060
Red Dead Redemption 2	6fps	108fps
Elden Ring	15fps	140fps
Fortnite	48fps	360fps

No contest here – a mainstream discrete GPU runs circles around integrated graphics!

Discrete GPU pros

Here are some of the biggest advantages of choosing a dedicated graphics card:

Far more processing power – Many more cores and beaucoup memory bandwidth for pushing high FPS and resolutions in games.

Optimized architecture – Discrete GPUs have designs tailor made for graphical workloads vs integrated graphics sharing CPU resources.

Memory capacity – Entry level discrete cards start at 4GB VRAM up to 24GB on high end models. Integrated graphics rely on a fraction of system RAM.

Cooling headroom – Big heatsinks let discrete GPUs run at much higher sustained clocks and performance levels.

Overclocking – Can‘t overclock integrated graphics much. But most discrete cards provide extra OC headroom for free extra performance.

Upgradeability – You can swap out a discrete GPU for a new one. Integrated graphics can‘t be changed or upgraded independently from the CPU.

Driver support – Discrete GPU drivers see much more optimization from AMD and Nvidia than integrated graphics drivers.

Better encodes/decodes – Discrete cards again have dedicated encoder hardware superior to most iGPU encoding blocks. Great for game streaming and video production uses.

Specialized features – Things like Nvidia DLSS, superior ray tracing, and proprietary technologies are only found on discrete GPUs.

Simply put, you‘re not going to get anywhere near the same graphical fidelity or performance from integrated solutions. Discrete GPUs dominate the gaming, content creation, and GPU compute landscapes.

Optimizing integrated graphics

Alright, let‘s finish up with some tips for getting the most out of your integrated graphics if you don‘t have the option of a dedicated GPU.

Overclock your CPU – This can provide a small boost to integrated graphics performance if thermals allow. Just don‘t expect miracles.

Update graphics drivers – Keep integrated graphics drivers up to date for best performance, compatibility, and new features.

Enable above default iGPU memory – Assign the max shared system memory possible to integrated graphics for more usable VRAM.

Close background apps – Cut down on unnecessary processes eating up CPU resources integrated graphics relies on.

Lower in-game settings – Resolution, textures, shadows, draw distance – put them all on low to maximize FPS.

Limit FPS – Capping FPS below monitor refresh can help sustain smoother performance on an iGPU.

Add more RAM – Particularly for AMD APUs, more system RAM improves integrated Vega graphics performance.

External cooling – Laptop cooling pads and external fans can help reduce thermal throttling of an iGPU under load.

Undervolt your CPU – Reduces temperatures allowing integrated graphics to sustain higher boost clocks for longer without throttling.

Tweak visual settings – Anisotropic filtering, ambient occlusion and anti aliasing hit iGPUs hard. Disable them first.

Stick to lighter games – Favor 2D indie games, strategy games, MOBAs, emulators and less demanding eSports titles where possible.

With these tweaks and compromises on visuals, integrated graphics can deliver decent low fidelity gaming and graphics performance. You just have to temper expectations, as iGPUs remain far behind their discrete counterparts.

The future of integrated graphics

Integrated graphics technology continues advancing each CPU generation. The shared system memory limitations remain a tough bottleneck though.

AMD‘s APUs with Vega graphics scale well with faster RAM. But high speed memory costs disproportionally more than typical DDR4 RAM.

The gaming performance is still lacking overall. And drivers rarely see the same level of optimization from AMD and Intel compared to their discrete graphics support.

But new architectures like Intel‘s Xe graphics in their forthcoming discrete cards may trickle down to improve integrated performance too.

Higher bandwidth memory technologies, better fabrication techniques enabling more iGPU cores, and backported optimizations from big GPUs could move the bar for integrated graphics.

But dedicated GPUs will always have fundamental advantages. More diespace for cores and memory, greater power and thermal headroom, specialized architectures, etc. make discrete GPUs ideal for gaming rigs.

Integrated will continue handling basic graphics adequately. It will be exciting to see how much they can close the gap to low-end discrete GPUs in the coming years. But high end discrete cards seem safe for the foreseeable future.

The bottom line

Hopefully this overview gave you a realistic picture of integrated vs dedicated graphics capabilities and limitations!

Integrated GPUs are plucky and efficient for basic gaming and graphical needs. Especially in laptops and budget systems where cost and power are at a premium.

But for AAA gaming, content creation, high resolution and refresh rate displays, GPU compute needs, and maximum eye candy, a dedicated Nvidia or AMD card remains the only real option.

If your uses demand GPU power and your system has room for the card, discrete graphics provide an unparalleled experience. But integrated solutions have gotten impressively competent for more general work and play!
