Product Description

Are you fed up of your system crashing too many times and not able to perform the various multi-tasks that it should perform? Maybe you should change the brain of the computer! Made with the latest technology, the AMD A6-6400K Richland 4.1GHz Socket FM2 65W Dual-Core Desktop Processor AMD Radeon HD is here to speed up your system with its unmatched specs. Now let your computer perform tasks at lightning speeds without any kind of interruption.

Features and Benefits

This product is a CPU / Microprocessor that can be installed in your desktop. It is from the AMD A6 series while the model number is A6-6400K. The frequency of this processor is 3900 MHz while the turbo frequency is 4100 MHz. Microprocessor frequency specifies the operating (internal) frequency of CPU's core. The higher the frequency is for a given CPU family, the faster the processor is. The boosted P states are 4100 MHz at 1.275V and the other is 4000 MHz at 1.15V.

The microarchitecture of this AMD dual core desktop processor is PileDriver. The processor core is Richland while the core stepping is RL-A1. Each microprocessor core could be refined or tweaked multiple times without changing or adding any major processor features. The purpose of the tweaks is to eliminate existing errors, improve processor's stability or reliability, and enhance some electrical, thermal or other processor characteristics. Each new core revision with these changes is referred to as a core stepping, and the changes never affect CPU performance. The core stepping will see that it matches the processors for use in multi-processing system, get CPU that fixes certain errata, determine stepping-specific electrical and thermal characteristics and estimate your chances of successful processor over-clocking.

The CPUID of this device is 641f31 while the manufacturing process is 0.032 micron. The number of cores that are present are 2 while the number of threads are also 2. The data width is 64 bit with an integrated floating point unit. The level 1 cache size is a 64 KB 2-way set associative shared instruction cache and 2 x 16 KB 4-way set associative data caches. Level 1 cache, often called primary cache, is a static memory integrated with processor core that is used to store information recently accessed by a processor. The purpose of level 1 cache is to improve data access speed in cases when the CPU accesses the same data multiple times. For this reason access time of level 1 cache is always faster than access time of system memory. The level 2 cache size is a 1 MB 16-way set associative shared cache. Level 2 cache, also called secondary cache, is a memory that is used to store recently accessed information. The goal of having the level 2 cache is to reduce data access time in cases when the same data was already accessed before. It is used to buffer program instructions and data that the processor is about to request from memory. This also reduces data access time. All data that is requested from level 2 cache is copied to level 1 cache. Requested data stays in the secondary cache if it's an inclusive cache, and is removed from secondary cache if it's an exclusive cache. Secondary cache is usually unified, i.e. it is used to store both program instructions and program data. This AMD A6-6400K 4.1GHz processor is a uniprocessor that will speed up your system like no one else!
