AMD Radeon HD 6450 Launched: Low Cost DX11 Graphics Card

AMD Radeon HD 6450

AMD has launched a new level entry card: the Radeon HD 6450. For around US $55, you have a DX11 capable card with low power consumption which makes it perfect for HTPC (home theater PC) and other media apps. You can also use it for gaming (you can run Crysis 2 at more than 20FPS) but the HD 6450 is not intended for hardcore gaming. This low form factor, low power and low performance card is available with active or passive cooling.

The Radeon HD 6450 is the refresh of the Radeon HD 5450.
