You also get four times the memory capacity — up to 64 GB. Intel Acceleration Technology helps by cutting CPU overhead by up to 40 percent which lets the CPU handle the other tasks more efficiently. The Intel Xeon E5405 2GHz processor features four complete processor cores in one physical package. Significant CPU performance headroom, especially for multi-threaded applications, helps boost system utilization through virtualization and application responsiveness. Its 12 MB L2 cache increases efficiency of cache-to-processor data transfer, maximizes main memory to processor bandwidth, and reduces latency. Intel EM64T provides an enhancement to intel 32-bit architecture for the Intel Xeon E5405 2GHz by enabling the mobile processor platform to access larger amounts of memory. With appropriate 64 bit hardware and software, platforms used on an Intel processor supporting Intel EM64T can enable sue of extended virtual and physical
