SERVER
Server Processors
• Server processors generally have more cores than desktop processors in the same class, allowing them to complete more tasks simultaneously.
• Most servers use more than one processor.
• Multiple processors allows the server to keep running in the event that one of its processors fails.
Server vs. Desktop
• Validation• Server processors are put through all kinds of tests under stressful
conditions such as higher temperatures, strict environmental conditions, and high computing loads.
• Dependable• Server processors are designed for reliability. For example, if your desktop
processor were to somehow fail, the whole workstation becomes inoperable. Server CPUs have the smarts to be able to failover, in the case of a dual CPU server, without having to crash or shutdown.
Server vs. Desktop
• Higher trafficking• Server CPUs are designed with buses that operate at much higher
frequencies (bandwidth). This means that they can process more data in and out of memory and other subsystems.
• Self Correcting• Server processors have the circuitry in place to correct memory errors that
can affect stability. The technology is called Error Code Correction (ECC).
Intel Xeon Processor
• Intel Xeon is a high-performance version of Intel desktop processors intended for use in servers and high-end workstations.
• Xeon CPUs have the same features as Pentium 4/D, Core 2 Duo/Quad desktop microprocessors.

Qualcomm-Snapdragon
Release: Q1 of 2013
Snapdragon 800
ZTE Grand Memo
News Flash: ZTE Grand Memo was just announced to be the first device to use the Snapdragon 800
Asynchronous Symmetric Multiprocessing
Qualcomm custom designed their own microarchitecture, called “Krait,” based on the ARM instruction set.
Technology can throttle the frequency of each CPU core independently, which makes the design more power efficient.

Variable Symmetric Multiprocessing Architecture
Variable SMP architecture enables four performance cores to be used for max burst, with each core independently and automatically enabled and disabled based on workload.
2MB L2 cache can be dynamically allocated to any CPU
