The youtuber dunno what he is doing... It is pointless to compare like this.

The test system used was:
System:
Windows 10 Pro
AMD Ryzen 7 3700 4.3GHz
GIGABYTE X570 AORUS PRO
GeForce RTX 2080 Ti 11GB
RAM 16GB DDR4 3200MHz CL16
RAM 16GB DDR4 4400MHz CL19

For all Ryzen 3000 (Matisse) , if you go above 3800Mhz on memory, you will get additional 8ns of latency for memory because FLCK and UCLK is unsync . That is assuming you can run infinity fabric clock at 1900Mhz which is what most people hit at the very best.

The 1 and only way to compare is, 3800Mhz on memory using the tightest timing you can do while running Infinity Fabric clock at 1900Mhz. Something like CL15 3800Mhz .

Running 4400Mhz on a Ryzen 3000 is really pointless.

3800Mhz CL14 -> 65ns memory latency
4400Mhz CL19 -> at least 77ns memory latency

Nolaa... Run the 4400Mhz CL19 at 3800Mhz but lower the timings.

Ryzen 4000 nobody knows what characteristic it has. It is a brand new architecture.
