The Asus EAHD4870X2 card uses AMD’s standard ATI Radeon design. The Radeon HD4870X2 has two graphics chips on a single PCI Express graphics card. It has 2GB of DDR 5 video memory and a faster clock speed. The chips are products of a 55-nanometer manufacturing process.

Radeon EAHD4870X2 has a built-in audio processing capability. The card’s HDMI port can be used to pipe out digital audio, via an included DVI-to-HDMI adapter. The card can run all the new features in Windows Vista, including the forthcoming DirectX 10. The core clock speed is 750 MHz while the memory clock speed is 3.6GHz.

EVGA's GeForce GTX 9800+ Super clocked edition has basically the same price-performance benefit as its Radeon HD 4850-based graphics card competition. With identical bang-for-the-buck, the main reason of liking this card is demand power efficiency, but you should turn to ATI's card if your PC has limited upgrade room. Manufacturer of EVGA Sold individually Products features of NVIDIA unified architecture with full Microsoft DirectX 10NVIDIA SLI ready to use. NVIDIA Pure Video HD technology PCI Express 2.0 supporting Two dual-link DVI, and one HDTV Dual-link HDCP capable OpenGL 2.1.

NVIDIA’s GeForce GTX 9800 added with chip debuted was last July for around $230. In this "Super clocked" design from EVGA, NVIDIA’s chip has its unique core clock speed boosted to 756MHz, from its stock 738MHz setting.

The GeForce GTX 295 graphics card with CUDA technology deals not only with providing a world-class gaming experience, but it also delivers Graphics Plus. An experience can be done of jaw-dropping PhysX gaming effects, stereoscopic 3D, and lightning fast video and image processing all accelerated by the GPU.Somewhat it experiences a new world of realistic physical motion and massively destructible environments, strapping on NVIDIA GeForce 3D Vision glasses to game in true stereoscopic 3D, trans coding HD videos in minutes with portable video player, or rapidly editing digital images using Adobe CS4, the GeForce GTX 295 graphics card does it all with mind blowing performance.

In today’s world of cut throat competition every other corporation is trying extensively hard to develop technologies better than other. In this race of RAM development, there is extreme competition for introduction of world’s fastest memory for multimedia applications. There are introduction of many fast memory types –

• XDR – XDR is a Rambus-developed technology that moves the data at 8 bits per clock cycle. The data rate in this case is 8GB/sec. The data rate of DD2-400 is 0.8GB/sec, and this shows that XDR is ten times faster than DD2-400
• In fact this is not it but there is still more to come.
