Radeon HD5450 Features

The feature set of the ATI HD5450 video card is nearly identical to the entire HD5xxx series. The important differences are all related to the fact that the HD5450 chip is half the size of the HD5670, with half the transistors and a small fraction of the processing power. For those who first saw the monster version of this graphic at the launch of the 58xx series, it's amazing how little is left in the center of the diagram; only 2 SIMD Engines with a total of 80 Stream Processors. Rest assured; the architecture diagram may have gotten smaller, but the feature list hasn't shrunk at all.

1. Driver support scheduled for release in 2010
2. Driver version 8.66 (Catalyst 9.10) or above is required to support ATI Eyefinity technology and to enable a third display you require one panel with a DisplayPort connector
3. ATI Eyefinity technology works with games that support non-standard aspect ratios which is required for panning across three displays
4. Requires application support for ATI Stream technology
5. Digital rights management restrictions may apply
6. ATI CrossFireX technology requires an ATI CrossFireX Ready motherboard, an ATI CrossFireX Bridge Interconnect for each additional graphics card) and may require a specialized power supply
7. ATI PowerPlay, ATI Avivo and ATI Stream are technology platforms that include a broad set of capabilities offered by certain ATI Radeon HD GPUs. Not all products have all features and full enablement of some capabilities and may require complementary products
