This quad core processor features K10 microarchitecture, an Agena processor core, and B3 core stepping. The K10 architecture of this AMD Phenom X4 2.5 GHz processor introduces optimization features, such as Dual Dynamic Power Management, which reduces the voltage of all microprocessor cores and makes usage-based decisions when adjusting the voltage of the integrated memory controller. It also usesIndependent Dynamic Core Technology, which adjusts the frequencies of individual cores depending on their usage, operating heavily loaded cores at maximum frequency and lightly loaded cores at low frequencies to reduce power consumption. This AMD 9850 processor also features Level 2 and Level 3 cache at four 512 KB and 2 MB, respectively, making this AMD Phenom X4 2.5 Ghz processor an ideal choice for multitasking, high-volume environments. AMD optimization features, such as 3DNow! and the SSE, SSE2, SSE3, and SSE4a instruction sets on this AMD 9850 processor further enhance its rich media capabilities. With AMD64 technology allowing the AMD Phenom X4 2.5 GHz processor to address multiple applications, this unit is a diverse and high-functioning quad core processor that can enhance any compatible desktop setup.
