It has only been five days since ATI released the ATI Radeon HD 5450 video card, but they are back at it today with the announcement of the Radeon HD 5570 video card. This card was designed to be an energy efficient, low-profile, DirectX 11 card for small form factor PCs. It also happens to pack a pretty mean punch as it has a Compute Performance rating of 520 GFLOPS for a price tag of just $79. The Radeon HD 5450 that was released last week costs a mere $49, but is rated at only 104 GFLOPS. The bottom line here is that the Radeon HD 5570 has four times the compute performance for an extra $30 (a 61% price increase).  Those that are looking to build a Home Theater PC (HTPC) or Small Form Factor (SFF) that want some muscle now have a choice between these two budget friendly low-profile graphics cards.
