What effect does memory have on a10-7890k performance

As we all know, dual-channel, high frequency memory has a great influence on the performance of Apu, especially in the game experience. Today we're going to test the performance of AMD's new flagship APU a10-7890k at different memory frequencies and channels, to see how much memory affects APU performance.

　　About a10-7890k Processors

A10-7890K is AMD introduced this year's new flagship APU processor, the use of four nuclear design, the default frequency of 4.1GHz, accelerate up to 4.3GHz.

Graphics, a10-7890k built-in Radeon R7 GPU, with 512 stream processors, core frequency 866MHz, the official memory frequency of the highest support ddr3-2133, the author will be in the motherboard BIOS set different memory frequency and single dual channel, testing the current mainstream several games, Compare the set dominance of Apu to change.

　　The test platform is as follows:

Test Platform Configuration

We will test 4GB DDR3 2133 memory, 4gb*2 DDR3 1866 memory, 4gb*2 DDR3 2133 Memory Test 3DMark score, as well as the game "League of Heroes", "through the FireWire," "Biochemical Crisis 6" in the performance.

　　New 3DMark

The new 3DMark provides users with a number of functions such as benchmarking and functional testing. In the benchmark, including our familiar fire strike tests, which include a variety of strengths, users can choose the corresponding test project according to the performance level of their platform. Let's take a look at a10-7890k's performance first.

A10-7890k scored 4581 points under 4GB DDR3 2133 Memory single channel

A10-7890k scored 4781 points under 4gb*2 DDR3 1866 memory dual Channel

A10-7890k scored 6595 points under 4gb*2 DDR3 2133 Memory dual Channel

From the data, it can be seen that the high frequency memory dual channel has a considerable impact on APU, 4gb*2 DDR3 2133 exceeds the 4GB DDR3 2133 30%! High frequency dual channel to APU important self-evident.

1. League of Heroes

"The League of Heroes" is referred to as "LOL" by Riot Games developed and released a Windows and Mac OS x platform under the multiplayer online tactical Arena (English: MOBA (genre)) (MOBA) game, deeply favored by the vast number of game enthusiasts.

Hero League Score

a10-7890k is averaged at 41.71 frames under 4GB 2133, with an average of 78.51 frames at 4gb*2 1866, and an average of 2133 frames under 4gb*2 90.45.

2, through the FireWire

"Through the Line of Fire" (Cross Fire, referred to as CF) is the Korean Smile Gate Company launched in 2008 in the era of the Network Battle Game (2007 years), in mainland China by Tencent operations. "Through the line of Fire" is a first-person shooter game online game, players play control of a gun fighters, and other players to fight.

a10-7890k is averaged at 117.2 frames under 4GB 2133, with an average of 128.3 frames at 4gb*2 1866, and an average of 2133 frames under 4gb*2 140.38.

3, Biochemical crisis 6

"Biochemical Crisis 6" is a Japanese Capcom company launched the action adventure game, the founder of the three true division. The story of "biochemical crisis 6" is that since the raccoon, the President of the United States has uncovered the truth for the past ten years, Leon S. Kennedy, one of the survivors and the president's personal friend, has had to face a changed president after a biological terror attack, And make the hardest decisions of your personal life.

Biochemical Crisis 6 Test score

a10-7890k is averaged at 18.2 frames under 4GB 2133, with an average of 23.4 frames at 4gb*2 1866, and an average of 2133 frames under 4gb*2 32.16.

　　Test Summary:

APU is composed of two parts of the calculation module, CPU and GPU rely on a variety of APIs work together, so the two computing modules will inevitably face the problem of resource sharing, memory controller to share, memory to share. From the test data, it can be seen that the average elevation of the two-channel memory is above 30%, and the memory frequency has obvious effect on APU. Therefore, the formation of APU platform friends, or spend more money group of memory double channel, will get 1+1>2 effect.

Because AMD has not yet supported DDR4, and this a10-7890k only supports DDR3 2133, does not play out the full performance of memory, wait until the next generation of Bristol Ridge APU Support DDR4 memory, I believe that high frequency memory will also bring higher graphics performance space!
