Choosing a Graphics Card

 

       Graphics Card Comparison

 When it comes time to buy a new graphics card, the number of choices can be staggering. Add to that the names of graphics cards, featuring long lists of confusing specs and marketing jargon. How can you tell one card from another? In this graphics card comparison guide, we'll explain the three features that really matter most: processor name, memory, and number of bits.

 

 

       Processor Names

 When undertaking a graphics card comparison, you'll quickly discover there are two major brands of processors, GeForce and Radeon. You can compare two of the same brand based on their model numbers. For example, a GeForce GTX 690 has a newer and more powerful processor than a GeForce GTX 650. However, it's much harder to compare a GeForce against a Radeon card because their numbers don't really relate to each other. Both brands make quality processors, though, so either one may work for you.

 

 

      Memory Explained

 One big difference you'll see in graphics card memory has to do with its two types, DDR and GDDR. DDR is generic memory. The G in GDDR shows that it is dedicated to working with graphics. While some people consider GDDR superior, either kind of memory will work well for you.

 

 Another difference you'll see with memory is the amount on each card. The more memory you have, the more your card can do for you. You'll need at least 512MB of memory to run graphics-intensive games and software at minimum settings. This graphics card comparison guide recommends that you get at least 1GB to 2GB of memory so that your card will hold up further into the future.

 

 

       Bits Simplified

 The number of bits on a card usually ranges from 64 to 512. This number tells you how much information can be moved by the card at once. A 64-bit card may be easy on the wallet, but it is significantly slower than a 512-bit card. A 256-bit card is sufficient for all but hardcore gamers and graphics professionals.

 

 

      Tying It All Together

 When graphics cards have lots of memory but low bit rates, that memory becomes a flood trying to work its way through a straw. But a card with a high bit rate and low memory isn't going to help you, either. When you have your price point and are picking your processor, the best graphics card comparison comes from balancing memory and bit rate.

 

 

    Extra Features

The other information you will see about a graphics card falls into a few categories:

 

Display ports available on the card (such as HDMI for an HDTV connection)

 

Slots (almost all recent PCs use PCI-Express)

 

SLI-Ready, a technology that allows multiple graphics cards to work together
