CPUAMD FX-4350: review and testing

AMD FX series is currently unique among all popular lines for desktop PCs. It may interest users who don’t want to overpay for a built-in graphics core. This is important in case when you want to build a gaming computer with efficient graphics card. The second category is the buyers who are fond of overclocking (all processors in this series have a good overclocking potential).

AMD FX-4350

In this article we will introduce you to a representative of the younger models a high-performance lineup AMD FX called “AMD FX-4350.” Novelty is equipped with four cores with maximum dynamic frequency up to 4300 MHz. It has an unlocked multiplier, which gives good overclocking capabilities.

Packaging, set of delivery and design

AMD FX-4350

Processor AMD FX-4350 comes in a familiar package made in the series AMD FX colors. Its front side contains an illustration that represents the solution with an unlocked multiplier.

AMD FX-4350

The back side of the box has a list of its contents in different languages. Also here you can notice part of the sticker with printed bar code and serial number of CPU.

AMD FX-4350

Supplied set of AMD FX-4350 include:

  • cooling system;
  • sticker on the computer case;
  • Quick Installation Guide of CPU and cooling system.

AMD FX-4350

The heat-spreading lid contains the model name and labeling. At the bottom there is information about place of chip production (Germany) and the final assembly (Malaysia).

AMD FX-4350

On the reverse side there is a set of thin copper contacts that are compatible with the CPU socket Socket AM3+.

Cooling system

AMD FX-4350

The scope of delivery includes compact cooling system, equipped with copper heat pipes and nickel-plated radiator fins. In general, similar cooling systems are supplied with other series of processors AMD FX, TDP which is located at 125 W (for example, AMD FX-8370).

AMD FX-4350

Blowing function is performed by fan Cooler Master FA07015E12BMC (12 V; 0.7 A) with a diameter of 70 mm, which is mounted on a special plastic box. It is connected to the motherboard by a standard four-pin connector, which allows you to control the speed of blades rotation by PWM method.

AMD FX-4350

The radiator is not in direct contact with the processor, but through a special copper base, covered with a thin layer of thermal compound. This allows to distribute heat more evenly over the entire area.

AMD FX-4350

The process of heat removal is provided by four copper heat pipes, spread it over stepped heatsink fins. The whole structure is securely fastened using standard metal clips and a small plastic latches.

Performance analysis

AMD FX-4350

AMD FX-4350 consists of four processing cores that can operate in four-thread mode. Firstly we realized a test under full load with the utility LinX 0.6.5, during which technology AMD Turbo Core 3.0 has been disabled. In carrying out the tasks CPU clock rate stood at 4200 MHz with multiplier "x21" and the reference frequency of 200 MHz. Core voltage was around 1,344 V.

AMD FX-4350

Sometimes the core frequency rises to the level of 4300 MHz with multiplier "x21,5", which corresponds to the maximum stated parameters with activated technology AMD Turbo Core 3.0. The voltage dropped to 0.864 V.

AMD FX-4350

In general, during continuous load most of the time (based on the program AIDA64) processor was operating at a frequency of 4200 MHz. Looking at the chart, sometimes it drops to 4100 MHz.

AMD FX-4350

During testing, the core voltage varied in the range of 1,320 - 1,366 V.

AMD FX-4350

During testing we used bench cooling system, and the CPU did not exceed the temperature of 52°C.

AMD FX-4350

After the transition to the idle mode, the processing speed was decreased to 1400 MHz with multiplier "x7" and the voltage 0.864 V.

AMD FX-4350

Distribution of cache is performed as follows. 16 KB of L1 cache per core with 4 channels of associativity are allocated for caching data. For instructions there are 64 KB of L1 cache with 2 channels of associativity for each dual-core module. There is a 2048 KB of L2 cache with 16 channels of associativity for each dual-core module. Additionally there is 8 MB of shared L3 cache with 64 channels of associativity.
