Whether to buy an OC (Overclocked) or Non-OC graphics card has always been a popular topic of great debate. It can be very confusing sometimes and most of the users may face a hard time deciding on which graphics card (OC or Non-OC) to get for their gaming needs. Well the answer to this question is not straightforward as there are many factors that come into play when choosing from an overclocked and non-overclocked graphics card.
Nowadays you can find different models of graphics card (with the same GPU) from different graphics card manufacturers. Some of them are just plain vanilla Non-OC variants, some are slightly Overclocked variants and the top ones are the highly overclocked or the Extreme OC variants. This can make the selection procedure more difficult because of the different varieties available for the same card but here I am going to make a complete comparison between OC and Non-OC GPUs so that you will not face any hard time in selecting the right graphics card in future. Non-OC or Non-Overclocked graphics cards are also known by Vanilla or Plain variant graphics cards.

OC vs Non-OC Graphics Cards Comparison
Here is a detailed comparison of OC and Non-OC graphics cards (with same GPU) based on different factors.
Size / Form Factor
Non-OC graphics cards are generally smaller and compact in size compared to the OC graphics cards. This is because OC graphics cards require a beefy GPU cooler and more components e.g. VRM (Voltage Regulator Module) compared to a non-OC graphics card running at stock speeds. They are generally taller and a bit longer in size compared to the non-overclocked graphics cards having the same GPU within. OC graphics cards also have better build quality compared to a non-OC graphics cards. Also, OC graphics card are better looking than the plain Non-OC variants because of their fancy design but they are a bit heavier.
GPU / Memory Clock Speed
Non-OC graphics cards run on the stock speeds that are defined by the GPU manufacturer while OC graphics cards run on higher GPU and Memory speeds. Some overclocked graphics cards only have higher GPU clock but some may also have higher memory speeds. The amount of overclocking present in an OC graphics card depends on the GPU model and the cooling provided to it. This is because some GPUs have higher overclocking potential compared to others. and even graphics cards with same GPU can have different overclocking potential or capabilities.
Below you can see the comparison between ZOTAC GeForce GTX 1060 Mini which is a non-OC graphics card and ZOTAC GeForce GTX 1060 AMP! Edition+ which is an OC graphics card and runs at considerably higher GPU and Video Memory frequencies or clock speeds.
|ZOTAC GeForce GTX 1060 Mini||ZOTAC GeForce GTX 1060 AMP! Edition+|
|GPU Clock||1506 / 1708 MHz (Base / Boost)||1607 / 1835 MHz (Base/Boost)|
|Memory Clock||8 GHz||9 GHz|
|Memory Size||6GB GDDR5 (192-bit)||6GB GDDR5 (192-bit)|
|Fans / Cooling||Single Fan, Aluminum Heatsink||Dual Fan, Heatsink with Copper Heatpipes|
|Card Dimensions||174mm x 111.15mm||210mm x 128mm|
Cooler (Fan / Heatsink)
A non-OC regular graphics card comes with a basic GPU cooler with one fan only most of the time. On the other hand, an OC graphics card generally comes with dual or triple fans with a heatsink equipped with copper heatpipes for better heat dissipation. Some OC graphics cards also come with liquid cooling solution such as hybrid cooler with water cooling + fan or Water block cooling that is used with custom water cooling kit.

OC graphics cards generally have better components quality and does have more Voltage Regulator Modules (VRM) / Power Phases as to provide stable power during overclocking. This is because overclocking requires considerably more power from the power supply and it can lead to instability if the power supplied to the GPU is not stable and sufficient.
Well it is obvious that an overclocked graphics card will perform better than a non-overclocked one especially in games. The performance of an OC graphics card over the non-OC one can vary depending on the amount of overclocking and GPU. An overclocked graphics card may perform 5% to 15% better than a non-OC graphics card running on stock speeds.
Models & Features
All the major graphics card manufacturers have their own overclocked graphics card models. Some models come with less overclocking and some come with higher overclocking depending on their price and cooling involved. For example, Asus has their ROG STRIX series graphics cards, Gigabyte has AORUS graphics cards that are their flagship models and come with higher overclocking capability. These high-end overclocked graphics card models also come with extra features such as RGB lighting, metal backplate and high performance silent fans.
Non-OC graphics cards can also be overclocked but not by a huge margin because of their cooling limitations. On the other hand, an already overclocked graphics cards can be overclocked further to some extent resulting into much higher performance in gaming and 3D applications. You can overclock graphics card by using good overclocking softwares that can be downloaded free from internet. In my experience I have found that most of the times Nvidia GPUs are better at overclocking compared to AMD GPUs.

OC graphics cards consume higher power than the non-OC graphics cards. Also, an OC graphics card may come with additional 6-pin / 8-pin PCI-E power connectors. So, if you are buying an overclocked graphics card then you may have to buy higher wattage PSU than what is recommended for a non-OC graphics card with the same GPU.
OC graphics cards are expensive than the Non-OC counterparts. The difference in price may be bigger or lesser depending on the model of the OC graphics card. If it is a top of the line premium graphics card with high-end cooler and RGB LEDs then it will be priced considerably higher than the standard Non-OC graphics card.
At the end I would like to say that if you are on budget and does not care about overclocking or features such as RGB LED, metal backplate etc. then it is wiser to go with a Non-OC plain graphics card, but if you are an enthusiast and want the best performance out of it and want extra features then get the best available OC graphics card that can be overclocked further.
