The two giants of the gaming industry namely the AMD and Nvidia are busy innovating the technology and each year they introduce new exciting products. Since both have great deal of competition among the graphic card, so each try to manufacture cutting edge new video rendering engines. In order to increase sales, they keep on fluctuate the prices of cards, overall both develop reliable video cards but AMD has relatively more sales due to their lower price strategy, since it is targeted towards lower income gamer who need to build performance machine without spending a lot of money.
Nvidia -> GeForce GPU
AMD -> ATi Raedeon GPU
Cost Vs Performance for Nvidia & AMD:
Gamers around the world are hungry for performance delivering components, video rendering GPU are at the top of the list since they play the major role in creating game environment to keep the player indulge in the gameplay. When we talk about performance then undoubtedly Nvidia graphics technology under brand name of GeForce is far superior and best suit for any serious gaming or multimedia needs but the price is much more than AMD cards, this is the reason Nvidia cards are no the preferred option by many gamers. On the other hand AMD devlelop video adapter under the name of ATi Radeon delivers performance quite close to Nvidia but their prices are far lower than the competitor. This attracts millions of gamers from all the world to buy Radeon graphic cards for powering their gaming computers.
Another reason for AMD graphic cards huge sales is that their GPU can be easily optimized to increase clock-speed by altering the voltage from motherboard BIOS settings as well from the GPU software. Over-clocking ATi cards enables budget gamers to harness more performance out card that costs less price in comparison to Nvidia Geforce. AMD cards also delivers high memory bandwidth as well as comes with more discrete video RAM. This enables the graphics processor to run faster and render high quality images on the screen.
Nvidia -> Rock Solid Performance, Expensive Price
AMD -> Good Performance, Better Overclocking, Cheaper Price
But sometimes the performance can be same, so does the price. For example, Nvidia Geforce GTX Titan is an extreme graphics card and it cost around $1000, whereas the alternate provided by AMD is ATi Radeon HD 7990 costing $999. Both card manufacturers claims these cards are the world fastest and no third card can reach up to this performance threshold with 6 GB dedicated video memory.
