AMD FX-8350 "Vishera" CPU Review

AMD has given their desktop processing line a shot in the arm with the release of the FX-8350 processor nicknamed "Vishera." The Vishera, incorporating the new and improved Piledriver knowhow, is a major advancement over AMD's earlier Bulldozer core-based FX-8350 processor and sports numerous impressive features. An elaboration of the Vishera's characteristics, merits, and demerits:

Key Aspects 

Configurable up to 8 cores embedded with Piledriver technology
Unique unlocking and overclocking abilities
Performance of 4 GHz going up to 4.2 GHz with turbo boost
2-channel DDR3 memory of up to 1866 MHz
L2 and L3 cache of 8 MB each
Patented AMD OverDrive 4 programming framework
AMD SB950, FX CPU, and 990FX processor circuitry support

Performance and Internal Structure Analysis

The FX-8350 Vishera has a distinctive architecture built using 32-nanometer expertise. This proficiency has enabled the Vishera to become the foremost desktop processor to boast 4GHz speeds, which can be overclocked at 4.2 GHz in turbo core mode. The architecture's other state-of-the-art features are outlined below:
a) The Vishera has up to 8 cores spread over 4 Piledriver segments all controlled by AMD's proprietary OverDrive 4 programming mechanism. The higher number of cores facilitates faster clocking speeds, considerably lesser power consumption, and greater retention of electronic signal quality.
b) The Vishera possesses a Thermal Design Power (TDP) configuration of 125 watts imparting the processor with heightened cooling and the power to sustain intensive applications.
c) Inbuilt is a specially formulated Integrated Memory Controller (IMC) that can accommodate a 2-channel memory backup of up to 1866 megahertz. These features are boosted by the presence of 1.2 billion semiconductor devices in the Vishera's framework.
d) The Vishera has cache storage capacities of 8 MB each for both L2 and L3 (shared) caches thereby ensuring speedier processing of commonly used applications.          
e) Thankfully the FX-8350 processor has retained the compatibility faculties of AMD's previous processors. The Vishera supports motherboards pertaining to:

AMD FX CPU chipsets
AMD 990FX processors
AMD SB950 (Southbridge) chipsets
Users will need to, of course, tweak their BIOS mechanism to activate the Vishera.
f) The Piledriver construction of the Vishera has been significantly strengthened leading to greater speed, instructions-per-clock (IPC) ratings, and running frequencies. The L1 Translation Lookaside Buffer (TLB) has been increased resulting in higher translation speeds of virtual addresses as also enhanced hardware data pre-fetching and branch estimation capabilities. Moreover, the revamped Piledriver framework entails a sturdier L2 cache with distinguishing C0-stepping abilities.

g) The Vishera is also armed with:

A unique Clock and Voltage honing segment that can be used for optimizing turbo performance.
A multiplier that functions in an unlocked manner.
A technically sound encoder to output H.264 movies in a multi-threading manner.
Compatibility with Open Computing Language (OpenCL).

Powerful AMD processor for Graphics and Game

Limitations

The Vishera is not without its frailties. The FX-8350 loses out in the fields of maximum performance, IPC ratings, and single-threaded running when compared with Intel's Ivy Bridge as well as Sandy Bridge processing units. In addition, the Vishera usurps more peak power compared to the rivals listed above.      
         
Closing Remarks

Notwithstanding the minor flaws, AMD's Vishera processor is still well worth considering its outstanding all-round features. The icing on the cake is the relatively modest pricing – commencing at around USD 200 for a base version.
