AMD Stream TechnologyAccelerate the most demanding applications with AMD Stream technology and do more with your PC. AMD Stream Technology allows you to use the teraflops of compute power locked up in your graphics processer on tasks other than traditional graphics such as video encoding, at which the graphics processor is many, many times faster than using the CPU alone.
AMD Eyefinity multi-display technologyAMD Eyefinity technology maximizes your field of view across up to two displays, fully engaging your peripheral vision, perfect for gaming and multimedia applications.
AMD CrossFireX multi-GPU technologyAMD CrossFireX multi-GPU technology allows you to double graphics performance via dual GPU scaling.
AMD PowerPlayDynamically manage power efficiency and take control of your performance with AMD’s revolutionary AMD PowerPlay power management technology delivering high performance features when needed and conserving power when the demand on the graphics processor is low. This seemless technology dramatically reduces the overall power consumption allowing for break-through energy efficiency.
Pros: I own multiple AMD/ATI Radeon HD 5450 cards from Sapphire, XFX and PowerColor. All the cards meet my needs (I'm not a gamer). My heaviest demand is Windows Media Center (MCE). Other than the amount of DDR3 RAM, I thought the cards would be identical. Boy was I wrong. I am posting my results, comparing the three vendors.
Cons: The Sapphire (I own two) and PowerColor have 1GB of DDR3. The XFX has 512MB of DDR3. Using CPUID HWMonitor all four card cores run at 650 MHz. The DDR3 on the two Sapphire cards run at 667 MHz (above spec); the XFX DDR3 at 533 MHz (at spec); the PowerColor DDR3 at 400 MHz (below spec). All the cards are 64 bit, so card specs double the MHz. The Sapphire and XFX reduce the core and DDR3 MHz under light load (to reduce power and heat). The PowerColor remains constant at 650 and 400 MHz. Running the same (real life) workload (Windows MCE), the Sapphire utilization is ~28%; the XFX ~58%; the PowerColor ~60%. The Sapphire operates at ~47C; the XFX ~43C; the PowerColor ~49C. From visual inspection, the Sapphire has the largest heat sync (it wraps around the card). The XFX heat sync is smaller (only extends above the card). The PowerColor has the smallest heat sync. Windows Experience Index (Desktop Graphics, and 3D Business and Gaming): Sapphire (4.5 and 6.1); XFX* (2.7 and 5.4); PowerColor (3.4 and 5.7). * Note the XFX card only has half the DDR3.
Overall Review: By nearly every metric I measured, the Sapphire is the best; the XFX a near second (given equal DDR3); the PowerColor a distant third. I rate only two Eggs mostly because the DDR3 is not to Spec.
