OC vs non-OC GPUs

Jawad14 · October 4, 2019

Whats the difference between an OC card and a non-OC one? For example, the RTX 2080Ti comes in 2080Ti OC and 2080Ti non-OC. And is it worth to spend a little more money to get the OC version of a graphics card like the 2080Ti OC ?

OC models usually bring higher max power limits which can allow greater overclocks. Could easily make a non-OC model carry OC model's power limit with a simple BIOS flash though (yes it's just a firmware change between the two models)

There big differences in models when it comes to 2080 tis.

First there are two different GPU types, A and non A, or

TU102-300A-K1-A1 = from 1650MHz to 1770MHz Boost Clock

TU102-300-K1-A1 = 1545MHz Boost Clock

The non As have less of everything. Here is a chart. https://en.wikipedia.org/wiki/GeForce_20_series

Even the As can be put into two groups and that is the difference in power delivery.

To give you an Idea here are the differences in my two 2080 tis.

Maximum power on my XC is 338 watts and on my FTW3 Ultra it is 373 watts.

The FTW3 Ultra always wins in benches even at lower clock since it can draw more power.

All 2080 tis can be overclocked but the high power limit A chips will give you the best results.

wow okay got it. So just confirm this to me .. the 2080Ti(s) that are OC will be the TU102-300A-K1-A1 ..... On the other hand, 2080Ti(s) that are non-OC will be the TU102-300-K1-A1 , is that right? Or thats not really necessary?

Second thing is that how to know which card on the market is the A version of the 2080Ti and which one is not? Because am soon going to be building a PC for myself and am planning on slapping a 2080Ti from ASUS, the Strix version on it.
