AMD A10-6800K Review – Richland-Based Desktop APU (Part 2)

Products lineup

A product range such as the Richland notice was able to pass through unnoticed in the past. The increased clock speed will only lead to the quiet appearance of new products on the price table with slightly higher product numbers. But AMD wants to make some noise and the game with its products names. There is a new code, the old graphics core has got a number of new products and the new APU belongs to the 6000 line.

Entire A-Series Stack

Entire A-Series Stack

The only problem is the Richland platform APU that is not advanced enough to replace the Trinity form. They just add to it. The older products are mixed with new ones, so any correlation between performance and the number of samples product lost. Some 5000 Trinity APUs can be faster and more functions than 6000 Model Richland APU, and potential buyers can feel totally confused.

With the new version is released, the entire product line of socket FM2 APU now looks as following:

The products list

The products list

A list of the product number and the graphic core does not reflect any technological improvements, so you can ignore them completely. The only difference between the old and the new APU is about their clocked speed, and even this difference is not significant. The quad-core A10-6800K and A10 6700 are faster than A10-5800K and A10-5700 from 5 to 7% (in terms of both x86 and graphics cores). The quad-core A8-6600K and A8-6500 are accelerating faster than the A8-5600K and A8-5500 10%. And the new dual-core A6-6400K is faster than the A6-5400 in term of clocked speed about 6-8%.

As before, the Richland APU includes a number of K versions which have an unlocked frequency multiplier. Please note that the high-end overclocked APU is friendly with quad-core x86-, A10-6800K and A8-6600K, have a TDP of 100 watts, while the socket FM2 is different with APU that is more economical than 35 watts. On the other hand, the K line is faster than 200 MHz. Consider that graphics performance is very important for the APU A10-6700 seems to be an interesting pattern. It is quite economical. Its computing performance is equivalent to A10-5800K and its graphics core offers the highest performance among all socket FM2products.

Though, we have got 100 watts Richmond for our tests. AMD A10-6800K is used by AMD processor to introduce the benefits of the design of this CPU, so it has many x86 cores and good processor and all of its clock speed are at maximum. Moreover, it is only socket FM2 processors that officially support DDR3-2133 SDRAM.

The frequency ranges

The frequency ranges

The specified frequency in the range of 4.1 to 4.4 GHz does not give us any clue about how the A10-6800K uses Turbo Core technology. Then this really becomes more active than before, so the CPU spends most of its time working in the 4.2 to 4.3 GHz. If not all of its cores are being used, the CPU can even achieve a maximum speed of 4.4 GHz.

Trinity is used to reduce its clock speed at continuous and high multi-threading load. Richland does not like that. Its Turbo Core technology can reduce the clock speed to 3.8 GHz in this case. Though, it does not do that often. The previous generation APUs will do so with much higher probability.

Integrated graphics core does not have automatic overclocking or power saving features. It always has clock speed at the specified 844 MHz.

Testing configuration and methodology

As the Richland generation representative that we keep trying to get to this test, A10-6800K processor, nothing else but a slightly improved A10-5800K socket FM2 processor, we decided to compare side by side with official similar APUs, however, it belongs to the generation of different designs. The competition from Intel will be represented by two LGA 1155 processors with equivalent price: Core i3-3225 (a dual-core processor with Intel HD Graphics 4000 graphics core) and Core O5-3330 (the least expensive quad-core, featured a slower Intel HD graphics 2500 graphics core inside, just likes the majority of the desktop Ivy Bridge processors at that time.

According to Intel Haswell concerned, there is currently no model for the desktop in the family, can even remotely compare with the socket FM2 Richland desktop processor. So, we're going to avoid comparing the advanced today’s models with it.

As a result, we ended up using the following hardware and software for our tests:

·         Processors:

ü  AMD A10-6800K (Richland, 4 cores, 4.1-4.1 GHz, 4 MB L2, Radeon HD 8670D);

ü  AMD A10-5800K (Trinity, 4 cores, 3.8-4.2 GHz, 4 MB L2, Radeon HD 7660D);

ü  Intel Core i5-3330 (Ivy Bridge, 4 cores, 3.0-3.2 GHz, 6 MB L3, HD Graphics 2500);

ü  Intel Core i3-3225 (Ivy Bridge, 2 cores + HT, 3.2 GHz, 3 MB L3, HD Graphics 4000).

·         Mainboards:

ü  ASUS P8Z77-V Deluxe (LGA1155, Intel Z77 Express);

ü  ASUS F2A85-V Pro (Socket FM2, AMD A85).

ü  Memory: 2 x 4 GB, DDR3-1866 SDRAM, 9-11-9-27 (Kingston KHX1866C9D3K2/8GX);

·         Disk sub-system: Crucial m4 256 GB (CT256M4SSD2).

·         Power supply: Corsair AX760i (80 Plus Platinum, 760 W).

·         Operating system: Microsoft Windows 8 Enterprise x64.

We used the following driver versions

·         AMD Catalyst 13.6 Beta Driver;

·         AMD Chipset Driver 13.4;

·         Intel Chipset Driver;

·         Intel HD Graphics Driver;

·         Intel Management Engine Driver;

·         Intel Rapid Storage Technology

Calculate the APU types, all standards have been implemented without the discrete graphics card. The graphics cores are solely responsible for displaying the images on the screen.
