Microprocessors 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.
