| Q: | What is the Performance-Power Rating?
|
| A: | The refined Performance-Power Rating (PPR) system was developed through a third party resource, Synchromesh, to ensure that AMD and other companies could test embedded processors in an open-standards, impartial environment. The intent and result is to give developers and customers an accurate assessment of how the processor will perform in real-world situations, not by touting speeds and feeds. |
|
|
| Q: | How do design engineers use the PPR?
|
| A: | The Performance-Power Rating (PPR) helps designers accelerate the embedded processor evaluation process by accurately reflecting system performance combined with power dissipation metrics. PPR more closely reflects how processors work within a device or solution, putting performance in context with real-world usage scenarios. |

|
| Q: | What does PPR really measure?
|
| A: | The microprocessor and embedded x86 industry as a whole have moved toward de-emphasizing the importance of clock speed, and showing performance in context of customer use. AMD leads the embedded x86 processor market by being the first company to introduce a Performance-Power Rating for design engineers to accurately evaluate an embedded processor. This metric will aid designers in assessing power and performance. |

| Q: | What makes you think that design engineers will care about application performance?
|
| A: | Especially since they can now design for full Windows® functionality on even the smallest consumer and industrial devices, design engineers will be able to include features and functionality previously unavailable. Designers need to be mindful of power, heat and cost challenges for embedded environments. In these environments developers need to evaluate device power requirements equally, and sometimes see them as more significant than processor performance. Currently, power specs are often shown secondarily or are more difficult to find for design engineers. |
