The performance of the server's four channel memory is improved. How about the performance of the four channel memory

Hello everyone , I meet you again , I'm your friend, Quan Jun .

Four channel memory has been improved , But the cost performance is not very good , If you are an enthusiast, you don't need to think about anything , If it is a pragmatist, the performance improvement brought by the four channels may not be obvious in use .

Building a four channel memory is simple , There are enough memory card slots ,X79 Chipset of ,i7-3960K The processor of ,Apacer Yuzhan Cheetah DDR3-1600 2GB * 4 perhaps a pirate boat DDR3 1600 2GB*4 Memory module is OK , Of course, other brands of memory modules can also , This is just an example , Just four pieces of the same memory . But the processor must be better , Otherwise, it will become the bottleneck of memory performance .

Users upgraded from the old platform can continue to use the previous machine DDR3 Memory , Its performance can meet the needs of most users . If you want to install a brand new machine , So spend a little more money on 4 Pieces of memory can be put into place at one time , And single 2GB Memory can also meet the needs of game applications , And the cost of buying memory will not be very large .

As for the performance improvement , Just look at the data and comments below .

Chess test

First, let's start with chess , as everyone knows , Chess can be said to be a more objective test software to measure the multi-threaded parallel computing ability of the platform .

【 Analysis of test results 】：

From the actual test results, we can see , Multichannel + Large memory does not bring higher scores , In the four cases, there is no bottleneck for simple operation , Even a single channel can have very good performance . The results of the four specifications are more errors , At present, most memory specifications are 1333-1600 In this range , This small-scale operation has no bottleneck .

CineBench test

Next, let's test the sensitivity of graphics rendering to the number of memory channels and memory capacity , Use of test tools CineBench R11.5, This is also a professional testing software . The software can test the processor and graphics card respectively , And it can be compared with other performance samples . Compared with chess , This kind of test is more close to our daily work . So will it be more memory dependent in such professional applications .

【 Analysis of test results 】：

Same as the previous chess test , The increase in the number of channels and memory capacity still does not lead to a significant improvement in performance . The increase of quadruple channel number and memory capacity is not proportional to the increase of performance , It will inevitably disappoint people . although i7-3960X It's good enough , The demand can be satisfied if such a situation exists in a single channel , But such a result will still surprise many people .

AIDA64 Cache & Memory Benchmark

Next, let's see how the increase in the number of memory channels can affect the memory bandwidth , And the software that can be qualified for this test should be AIDA64 Cache & Memory Benchmark 了 . The software can objectively reflect the platform memory reading 、 Write and copy bandwidth .

【 Result analysis 】：

From the results we can see , Different from the previous test results , The increase in the number of channels can also lead to more objective bandwidth improvement . However, the improvement from single channel to dual channel is very obvious , However, the performance improvement from dual channel to three channel and then to four channel has once again encountered a small bottleneck . So we think that in terms of bandwidth , The bandwidth provided by dual channel memory can feed the memory controller of the processor .

PCMark Vantage test

PCMark It is also a regular customer in our test , The test tool can test the performance of each part of the platform , And give very impressive results . Here we use PCMark Vantage Rather than PCMark 7 The reason is that the former has a special test project for memory performance , Can better see the actual performance of memory . Next, let's take a look at the test results ：

【 Analysis of test results 】：

PCMark Vantage The test results are different from the previous tests , From single channel to three channel, the performance increases linearly , And when it comes to the fourth channel, the result is basically the same as that of the third channel . stay PCMark Vantage Under such test software , The four channels still do not show their advantages .

3DMark 11 test

After testing the computing performance and memory bandwidth , Let's take a look at the impact of memory performance on graphics processing power .

【 Analysis of test results 】：

It is basically consistent with the previous results , Dual channel can be said to maintain a good balance between performance and price , The performance improvement from the three channels is very limited . Even on highly configured platforms , Memory does not cause bottlenecks .
