Under the support of Ryzen and Vega, two major epoch-making architectures, AMD's new generation of APUs came to the world with great expectations and performed well in all tests. Xiao Bian's friends could not wait to prepare a small amount of money and they must immediately receive a piece of money. Get ready for a small computer that fits the game office. At this time Xiao Bian who is busy on the APU test platform asked him a word: How are you going to allocate memory? This time, my friend was shocked. Is this a problem? In order to verify the relationship between APU and memory, Xiao Bian selected some 3DMarks for game capabilities, Fritz Chess for pure computing power, and CineBench R15 for professional graphics applications to do some simple tests. Show him how APU fits Memory collocation.
complete in one step
Because AMD's processor itself is relatively large memory demand, coupled with APU integrated graphics card does not have memory, it is bound to borrow memory, which puts higher requirements on the memory bandwidth, so no doubt, high frequency + double Channel memory is the best solution to use with the APU. At present, DDR4 3200 is already the highest frequency memory that can be purchased in the market. Xiao Bian naturally uses high-frequency DDR4 3200 to set up dual-channel memory to run and see.
From the test results, the dual-channel + high-frequency memory combination is the best, can give full play to the APU's integrated graphics performance, but also help the system's memory performance. In fact, the result of this run has exceeded GT1030, which is really amazing, so if the budget is plentiful, this matching scheme is undoubtedly the most perfect.
Old memory continues to serve
In addition to using the latest and most expensive DDR4 3200, there is still the old memory continues to use, such as previously bought DDR4 2133 or DDR4 2400 memory, want to continue to use on the APU platform, in which case the result will be how? From the test results, even if the dual-channel DDR4 2400 memory, the theoretical bandwidth is only 75% of the dual-channel DDR4 3200, the gap is still quite large, this will cause serious impact? Although the dual-channel mode has been used, the performance of DDR4 2400×2 is still quite large compared to the best solution. Two of them are lower than the single-channel DDR4 3200. Surprisingly surprised, not surprised? In the graphics performance segment, the 3DMark performance is equivalent to 85% to 90% of the dual-channel DDR 4 3200, and the professional performance graphics performance is only about 80%.
Apparently, high-frequency memory has a large impact on APUs. There is a big gap between DDR4 2400 dual-channel performance and DDR4 3200 performance. However, it is better than nothing and it is always better than single-channel memory usage.
Future potential
Now that memory prices are still quite expensive, two DDR4 3200 memories may cause our budget to stretch. Then Xiaobian suggests that you can choose a single high-frequency memory to "make do" and wait until the price is more reasonable and then upgrade to double. Channel architecture, to give full play to the performance of the APU, of course, this approach will sacrifice some of the performance in the early stages. From the test point of view, the processor unit of the next-generation APU is obviously not very sensitive to the memory bandwidth, on the contrary, it is very demanding on the memory frequency, all CPU-related test scores are off, and the single-channel memory operation reaches 97% of the dual-channel even more. high. However, in the graphics performance test, the problem of insufficient bandwidth was exposed, and 3DMark performance and professional graphics performance were only equivalent to 65% and 73% of the dual channel.
This fully shows that without spending money ... In the case of budget constraints, the impact of a single memory on integrated graphics is very large, this configuration is only suitable for those who will definitely upgrade the supplemental memory in the near future, or not to the game Sensitive user use.

After seeing Xiao Bian's test, the friend also had an idea of ​​how to make full use of the little money in his hands. Then he opened the e-commerce page and shouted, "Go ahead, it's up to you!!"
