As these days, Computers are a need of everybody, the Graphics are a very important part of the computer for game play and other things. Nowadays the games are made on a vast scale and the games look so real that you hardly differentiate between a game and the real world. To make games look like this, new Graphics Processing Unit (GPU) is included in the Computer only for Graphics. Their are two main Companies which makes the GPU’s for computers – AMD Radeon and NIVIDIA . We have tried to differentiate between them to see which one is better than other.
Early days of graphics on the PC saw 3D cards like Nvidia’s RIVA 128 and TNT2 take on ATI’s Rage and Rage 128. But it was Nvidia who presaged the modern GPU or Graphics Processing Unit with the mighty GeForce 256 in 1999. ATI responded in 2000 with the Radeon graphics card. Ever since, successive generations of GeForce and Radeon GPUs have been leapfrogging each other in the race for graphics supremacy. Nvidia has the early advantage over the ATI’s Radeon. But in 2002 ATI turned the tables with the awesome Radeon 9700 Pro. The first GPU with fully programmable shaders, the 9700 Pro was massively more powerful than any graphics chip before.
Now Move into mid-range territory and direct comparison between ATI and Nvidia is currently a bit tricky. That’s because Nvidia is yet to release more affordable chips based on Fermi, the new DX11 architecture that underpins the GTX 480 and 470 GPUs. Consequently, the Radeon HD 5770 (£125), Radeon HD 5670 (£85) and Radeon HD 5570 (£72) are lording it without any DX11 competition and Nvidia makes older chipsets based on DX10 tech, such as the GeForce GTS 250 (£125) and GeForce GT 240 (£72).
Conclusion: What becomes of AMD graphics after two fruitless attempts at winning over the top-end market? The AMD Radeon HD 6870 failed to reach top-level performance that many expected, and was relegated to fighting off an army of factory-overclocked GeForce GTX 460′s that sell at a better price point. Now the Radeon HD 6970 proves that AMD doesn’t have a single-GPU answer to NVIDIA’s GeForce GTX 580. The DX11 discrete graphics market is already saturated with AMD Radeon HD 5000 series, diced into portions so thin that a mere $10 separates some products, leaving little room for additional growth. With the convincing likelihood that AMD’s Radeon HD 6900-series will miss the fast-approaching holiday season and the sales opportunities it brings.
