Verify how memory performance affects gaming performance with "Ryzen 5 2400 G"

APD released by AMD in February 2018"Ryzen 5 2400 G" & "Ryzen 3 2200 G"He is showing a good start. It is known that the performance of the built-in GPU of Ryzen 5 2400 G is greatly affected by the performance of the installed memory, but Tom's Hardware has verified the gaming performance per memory speed in detail, and as expected, "Ryzen APU The result is that kimo is using high-speed memory ".

AMD Ryzen 5 2400 G Tests: How Much Does Memory Impact Gaming?
http://www.tomshardware.com/reviews/raven-ridge-memory-scaling-benchmarks,5489.html

Validation is APUI Ryzen 5 2400 G, motherboardMSI B350 Tomahawk, Storage isSamsung PM 863 (960 GB), OS is done with Windows 10 Pro (64 bit) configuration. The key memory says a perfect correspondence to RyzenG. Skill FlareX DDR 4 - 3200 (8 GB)In addition to the number of various memory clocks, two types of access timing are verified, 14-14-14-34 (CL14) and 16-16-16-36 (CL36). In Ryzen CPU · APU, the "rank" of the memory has been closed up, but the memory we used this time is a single ranked one. By the way, regarding ranking, Ms. Shimano of Century Micro Inc.CommentaryYou can understand well by looking at.

◆ Single channel
In single channel state "Civilization VIThe frame rate of each clock is measured for each access timing as follows. The number on the left of the graph shows the minimum value and the number on the right shows the average value. It can be seen that the frame rate is constantly increased in proportion to the increase in the number of memory clocks and that the difference between CL14 and CL16 tends to increase as the number of clocks increases.


In comparison with the configuration that combines Intel Core i3-8100 and Pentium G4620 with NVIDIA GeForce GT 1030, it is fairly struggling in single channel environment. Of course, Intel CPU + Graphic Board NVIDIA graphic board configuration seems to have not improved so much that the gaming performance can be experienced by memory performance.


The average frame rate looks like this. The graph does not intersect, it seems that the memory performance is in all the scenes, and the performance does not reverse.


"The Witcher 3: Wild HuntThe result of "is not very different from Civilization VI.


◆ Dual Channel
Then measure the benchmark with dual channel memory. The average frame rate of DDR 4 - 3200 (CL 14) setting of Civilization VI is "57.6", clear frame rate up can be confirmed compared with single channel which was "33.9".


The Witcher 3 will surely improve performance and reach performance comparable to Intel Core i3-8100 + NVIDIA GeForce GT 1030.


◆ Four DIMM inserts
MSI B350 Tomahawk has 4 DIMM slots, it is possible to use 4 single memory of this time inserted. So, the performance with the insertion of 4 memory cards has also been verified. As for the single rank memory, as the official announcement of AMD support of up to DDR 4-2933 with inserting two cards and DDR 4-2133 with four cards inserted, the number of clocks is limited in inserting four cards, and even at CL16 DDR 4 - 3200 It did not pass the setting, DDR 4 - 2933 also said there was a problem.

Civilization VI benchmark results are as follows.


The result of The Witcher 3. The same tendency result was obtained as for the insertion of two pieces except that the upper limit of the clock number is not enough.


◆ Summary
As you can see from the benchmark results, Ryzen APU (Ryzen 5 2400 G · Ryzen 3 2200 G) can not bring out performance almost with single channel, dual channel is essential. It has also been confirmed that it is effective to increase the gaming performance by using memory with the highest possible frequency. Tom's Hardware already improved the BIOS of the motherboard, and the severity of memory that was at the time of the release of Ryzen 7 series was not nearly as much as the test of Ryzen 5 2400 G. I hope that gaming performance will be further improved by optimization around memory.

A so-called overclocking memory (OC memory) with a high number of clocks was often less expensive than a general memory, and scenes that can experience the performance difference are few in many cases. However, in terms of Ryzen APU, memory performance is overwhelmingly important to bring out the performance of the internal GPU, and it seems to be good expecting to improve gaming performance commensurate with OC memory price.
