Being the worldwide motherboard leader, ASUS offers a wide range of high-performance motherboards that can take advantage of Intel's 45nm next-generation processors. Providing awesome performance for today's and tomorrow's thread-intensive games and applications, the cutting-edge 45nm processors offer a significant performance boost while providing an overall more energy efficient platform.

Extreme Performance for Games and Applications

The 45nm CPU introduces new micro-architecture features for greater performance at a given frequency, up to 50% larger L2 caches, and expanded power management capabilities for new levels of energy efficiency. By increasing transistor switching speeds, this breakthrough will enable higher core and bus clock frequencies, allowing more performance in the same power and thermal envelope.

45nm Ready Motherboards

The chart below shows the ASUS motherboards that are currently 45nm CPU support ready. ASUS will always stay in step with the latest developments and provide hardware and firmware for optimal performance and functionality. More 45nm Ready ASUS motherboards are expected to be announced soon.
P5E3 Deluxe/WiFi-AP boosts up system performance with Intel® Core™2 Extreme processor QX9650 (45nm CPU).
