PC Graphics

[Mix4]

Hello everyone. There is a ryzen 5 5600g, Kingston FURRY Beast black [KF432C16BB/16] one bar, Gigabyte b550m ds3h and a 700 power supply. There are problems with the performance of the built-in graphics card, namely, not the performance in games that is shown in the tests. I found only one video where there was a test of single-channel and dual-channel memory and the difference was 2 times. Is this really the case, or will the difference be less significant? I apologize for my poor English, I wrote through a translator

Yes, the integrated graphics of the 5600G does not have dedicated graphics memory and must use the system memory. The Ryzen processor has two 64bit memory controllers, so when using two DIMMs in dual channel it's getting the full 128bit data width. With DDR4-3200 memory that translates to 25GB/s throughput. If you use a single memory module you are literally cutting that throughput in half to only 13GB/s. This hurts not only the CPU performance but also the IGP performance.

Compare that to a modern entry level graphics card like the Radeon RX 7600 that also uses a 128bit memory bus but with GDDR6 has 288GB/s memory bandwidth.

Thank you very much for the reply. I watched a lot of videos and discussions, but no one talked about it.
