Computer Hope

Introduction:

The world of graphics cards is constantly changing, even faster than the rest of the computer industry. This is intended to be a guide to what's on offer at the minute. This guide will be kept up to date if possible, but will inevitably fall behind slightly.  Last update: October 24th 2013.

For any specific questions, please create a new thread in the appropriate board, most likely hardware.


Jargon

AMD
AMD is a manufacturer of graphics card chips. These chips are added to other video cards and resold by other manufacturers - for example, you may see an Asus AMD Radeon HD7950 - this is an AMD Radeon HD7950, branded, packaged and supported by Asus.

Nvidia
Nvidia is ATI's rival graphics card manufacturer. Similarly, its cards are rebranded, repackaged and sold by other manufacturers, very seldom by Nvidia themselves, so you may see an EVGA Geforce GTX 780 which is an Nvidia Geforce GTX 780, branded, packaged and supported by EVGA.

GPU
GPU stands for Graphics processing unit - it's the chip on a graphics card that does all the work.

PCI-E (PCI Express)
The standard interface for graphics cards. It offers high bandwidth, meaning higher-performance cards. Most new cards available today are for PCI-E. Also sometimes abbreviated as PCI-X, although this is incorrect.

AGP (Accelerated Graphics Port)
This is the older interface for graphics cards. It provides less bandwidth than PCI-E, and has been completely replaced by PCI-E now. The newest card available for the AGP interface was the HD4670, the fastest was the HD3850.  Neither are common, and neither is a cost effective upgrade, especially as they're both quite old and not very fast by today's standards.

SLI (Scalable Link Interface)
This is Nvidia's technology to use two or more graphics cards together for increased performance. All you need are two identical Nvidia cards (the memory size can be different but the core must be the same) and a motherboard that supports SLI.  Most modern motherboards with more than one PCI-E slot will support SLI.

Crossfire
This is ATI's technology to use two or more graphics cards together for increased performance.  Identical cards are not necessary but the series must match, e.g. a 6850 and 6870 can be used together, but a 6850 and 6950 cannot.  A Crossfire capable motherboard must be used.  Almost all modern motherboards with two or more PCI-E slots support Crossfire.

DX11
DirectX 11. This is the newest in Microsoft's DirectX software series. It allows for better, more realistic graphics, but only the newest cards support this. Windows 7 SP1 or Windows 8 is required, earlier versions of Windows do not support DX11.  Graphics cards from the AMD HD5850 and Nvidia GTX 4 series and newer support DX11.  DX11 is coded in such a way that DX10 cards can run a subset of features, so if a card can run DX10 it can run DX11 games, just not with all the eye candy.

DX10
DirectX 10. This is the previous release of DirectX, supported from Windows Vista onwards. It requires an AMD HD2xxx series of Nvidia GTX 2xx series card or newer.

DDR2 memory
Double Data Rate v2 memory.  This is standard system RAM, used on low end video cards as video memory.  Cards using this memory will be quite slow.

GDDR memory
Graphics Double Data Rate memory.  Currently, there are GDDR3, GDDR4 and GDDR5 variations on the market.  Newer versions are faster than older versions.



Graphics cards
Below is a list of graphics cards, from highest to lowest performance.  This is not comprehensive, but covers most common cards from around 2006 onwards.  Some cards will perform better or worse than others higher or lower on the list in certain applications, this list should only be taken as a general indicator of performance so for any specific questions, please either research or create a thread in the appropriate board, most likely hardware
