Factory Overclocked vs Self Overclocked Graphics Cards Comparison

There are generally two types of graphics cards that you can find in the market whether from Nvidia or AMD. The first ones are the reference graphics cards or non-overclocked graphics cards that come with stock frequencies specified by the GPU manufacturer. Another is the overclocked graphics cards or overclocked (OC) edition graphics cards that come with higher GPU and VRAM frequencies and offers better performance than its non-overclocked brothers. However, overclocked graphics cards cost a bit more than non-overclocked graphics cards. Also, you may be able to overclock a non-overclocked graphics card but not by much. So, are these factory overclocked graphics cards worth the extra price or not? To answer this question, I am going to make a complete comparison between overclocked and non-overclocked / reference graphics cards, so that you can make an informed decision when buying a graphics card for gaming.

Factory Overclocked Graphics Cards

Factory overclocked graphics cards come with higher GPU & VRAM frequencies or they can be easily overclocked to higher GPU and Video Memory clock speeds. These overclocked graphics cards come with better cooling and some of them have more power phases to give the card extra stability during overclocking. Some overclocked graphics cards also come with a liquid cooler that offers higher overclocking potential and lower temperatures. Below you can see a factory overclocked graphics card from Zotac.


These factory overclocked graphics cards offer around a 10% to 20% performance increase over their non-overclocked counterparts. Also, they are a bit more expensive than their non-overclocked variants. These factory overclocked graphics cards can cost around 30 to 40 dollars (or maybe more) higher than the non-overclocked graphics cards. Almost all the graphics cards manufacturers offer OC edition graphics cards and the degree of overclocking depends on the card model, cooler used, and the number of VRMs or power phases used on the graphics card. Graphics cards using more fans (dual or triple fans), better heatsinks with copper heatpipes and a higher number of VRMs have better overclocking capabilities and are generally overclocked higher. Also, factory overclocked graphics cards consume a bit more power and may include more 6-pin / 8-pin PCI-Express power connectors as compared to the reference or Non-OC graphics cards.

Generally, there are two types of Factory Overclocked Graphics Cards:

Factory Pre-Overclocked Graphics Cards

These graphics cards come directly pre-overclocked from the factory or the manufacturer and you do not have to do anything through software or utility. You just have to plug these overclocked in the PCI-Express x16 slot, install the video drivers and just sit back and relax. When you run any GPU info software then you will be able to see higher GPU and VRAM frequencies in it.

Factory Tested Overclocked Graphics Cards

These overclocked graphics cards are tested for higher frequencies by the manufacturer but they come with the stock frequencies from the factory. So, when you plug these graphics cards in your PC and use GPU-Z or any other graphics card info tool to detect the GPU and Video Memory clock speeds then you will get the default stock frequencies shown there. These graphics cards come with their own overclocking software and using them you can easily overclock them to the higher tested frequencies with a single click (One-click Overclocking). After that, your graphics card will run at those higher overclocked frequencies and thus giving you extra performance in games and other applications. You can also reset the graphics card to their original stock frequencies any time you want. The only difference between these graphics cards and the pre-overclocked graphics cards is that in these graphics cards you have to perform some extra steps and use its GPU OC software to run them at their higher advertised speeds.



Can you overclock a factory overclocked card?

Yes, you can overclock a factory overclocked or already overclocked graphics card but this may not apply to all factory overclocked graphics cards. This is because some overclocked graphics cards have some room left for overclocking and some don’t. Also, if the graphics card is fitted with a good cooler, has more power phases, and allows voltage modifications then you may be able to overclock higher to extract every bit of performance from it.

Self Manual Overclocking of Non-Overclocked Graphics Cards

It is a fact that if you want to increase the performance of your graphics card then you have to overclock it. You can overclock your graphics card using graphics card overclocking software that can be downloaded from the internet for free. But there are some issues or dangers of manual or self overclocking. If done incorrectly then overclocking results in overheating of your GPU, VRAM & VRM and can lead to damage to your video card. Also, it can also result in the instability of your graphics card and this may cause freezing, BSOD, and frequent restarting in the operating system.


A non-overclocked graphics card generally comes with an average heatsink and fan. Normally you would see a single fan and heatsink without heatpipes on a non-overclocked graphics card. Also, their voltages are locked in the GPU BIOS and you cannot fiddle with it to achieve stable and high overclocks. Reference graphics cards from Nvidia and AMD come with a blower-type fan with average aluminum heatsink assembly and they generally run hotter and cannot be overclocked to higher levels. If your non-overclocked graphics card comes with a better cooling then you may be able to overclock it to the levels of the OC Edition variant of it. Generally, you will find small form factor (SFF) and low profile graphics cards come with stock frequencies. You can check out the guide on graphics card overclocking from the link given below.

Factory Overclocked vs Reference / Non-Overclocked Graphics Cards

  Reference/ Non-Overclocked Graphics Cards Factory Overclocked Graphics Cards
GPU / VRAM Clock Frequencies Default or Stock Clock Speeds specified by the GPU manufacturer Higher than the Stock Speeds
Cooling Average, generally comes with only one fan Better, comes with two or triple fans, and some high-end GPUs come with liquid/water cooler
Stability Stable at Stock Speeds / May remain stable at minor overclocked speeds Stable at even Overclocked Speeds
Power Consumption Normal as specified by the GPU manufacturer Can be higher than the Reference / Stock cards. Some may require extra 6-pin/8-pin power connectors
Features Normal Features Can be higher than the reference / non-OC cards e.g. LED lighting, metal backplate, etc.
Price Normal Higher than the reference/stock cards

So, which one to buy?

Overclocked graphics cards do offer some significant amount of performance improvements over reference graphics cards or non-graphics cards having stock frequencies. But are they worth the extra price? Well, it depends on the user requirements, preference, and budget, because if you can spend a few bucks more and want the best performing card in its segment then factory overclocked graphics cards really make sense. I personally do prefer the OC Edition graphics cards rather than buying the plain vanilla variant with stock frequencies.

On the other hand, if you are on a tight budget and are experienced enough to overclock a non-overclocked graphics card then you should get a non-overclocked variant of that graphics card. You may not be able to overclock it higher but you some overclock is possible.
