APU AMD A4-6320: review and testing

If you want to build the budget office or home computer one of the most important roles plays the correct selection of the processor. In many cases, one of the low-cost APU models from AMD will be suitable. The advantages of this solution are:

  • the ability to use inexpensive motherboard;
  • easier cooling system;
  • lower cost compared with a set of processor and discrete accelerator with the same performance.

AMD A4-6320

As you can see, the acquisition of APU has many benefits. If we talk about the hero of this review, AMD A4-6320, the advantages are extended by relatively low cost. As a result you will have a well-balanced computer for watching video and surfing the Web.

Package, content and design 

AMD A4-6320

AMD A4-6320 processor comes in white standard packaging typical for all APUs produced by AMD. They don’t have an unlocked CPU multiplier.

AMD A4-6320

The reverse side of the box features a delivery set in different languages.

AMD A4-6320

Delivery set of APU AMD A4-6320 includes:

  • cooling system;
  • quick guide for installing the processor and cooling system;
  • sticker for the computer case.

This set is typical for the majority of boxed processors and includes everything you may need to start the building the computer.

AMD A4-6320

Externally the APU also looks quite standard. Its heat-spreading lid has the manufacturer's logo, name and serial number of model. Also here you can find the list of countries of chip production (Germany) and final assembly (China).

AMD A4-6320

The reverse side of the device is equipped with a standard set of contacts that are compatible with the CPU socket Socket FM2. This means that AMD A4-6320 can be used in tandem with the new motherboards (Socket FM2+).

Cooling system

AMD A4-6320

The delivery set of today’s product under review contains compact cooling system which consists of the fan blades with a diameter of 70 mm and a small aluminum radiator. In general, it is quite typical for the APU with TDP level of 65 W.

AMD A4-6320

The active blowing is provided by fan Foxconn PVA070E12L (12 V; 0.20 A), which is attached to the radiator by means of conventional screws and it connects to the motherboard via a standard 4-pin connector. Speed adjustment of blades is supported by PWM method.

The radiator is in contact with the processor through a thin layer of thermal paste. The entire cooling system is attached by using standard metal staples and a plastic latch.

Analysis of technical features

AMD A4-6320

In case of disabled technology AMD Turbo Core 3.0, our APU AMD A4-6320 worked at a frequency of about 3800 MHz at multiplier of "x38", and a reference frequency of 100 MHz. The voltage on the core was at the level of 1,360 V.

After activation of technology AMD Turbo Core 3.0 the frequency of processor cores was increased. During the testing it eas in the range from 3800 to 4000 MHz. Core voltage varied from 1.312 to 1.4 V (most of the time it was on the level of 1,366 V).

AMD A4-6320

When using bench cooling system and during stress tests core temperature does not exceed 41°C, which is an excellent indicator.

AMD A4-6320

After moving to the idle mode the multiplier was decreased to "x18", and CPU clock speed has dropped to 1800 MHz. The power voltage was at the level of 0.904 V.

AMD A4-6320

Distribution of APU AMD A4-6320 cache memory is carried out as follows. L1 cache memory of: 16 KB per each of the 2 cores is allocated to the data with 4 channels of associativity, and for instruction has 64 KB with 2 channels of associativity. L2 cache memory: 1 MB with 16 channels of associativity. L3 cache memory is absent.

AMD A4-6320

Integrated memory controller supports DDR3 memory modules with a maximum frequency of 1600 MHz, which can operate in dual channel mode.
