2GB vs 4GB Video Memory Graphics Card Comparison

Many cards in the market now come with 2GB Video Memory and 4GB Video Memory variants, the 4GB Video Memory variants cost a bit more but is it worth the paying a bit more for it?

In this article I will be using the ASUS GTX 960 Turbo as the contender for the 2GB Video Memory while the 4GB Video Memory contender would be the ASUS GTX 960 STRIX with the core clock downclocked to match that of the ASUS GTX 960 Turbo.

By lowering the clock speed of the GTX 960, both cards now have matching processing speed. This will help identify the benchmark that takes advantage of the additional memory.

In Unigine Heaven 4.0 benchmark both cards show the same speed, same goes to Metro Last Light and BioShock Infinite.

Going on with newer games like say Shadow of Mordor and GTA Five, the benchmark goes in favor of the card with more Video Memory showing some 10 to 20% performance gain.

The Verdict

So is it worth paying a bit more for the additional Video RAM? Yes I think it’s worth it, especially if you have plans to add another GTX 960 into the setup for SLI goodness, you then have 4GB of Video Memory instead of just 2GB.
