Faster RAM will give your PC better performance in certain specific benchmarks, but in terms of actual benefit to most users, having more RAM available is almost always better than having faster RAM. Graphics cards include their own memory, so games aren't majorly affected by system RAM speed.
No there is really no such thing as Intel ram and AMD ram. It depends on if the two computers use the same memory type. A new computer uses DDR2 while an older computer would use DDR1 and an even older computer would use SDRAM.
Optimal RAM speed for Ryzen 7 2700X
The general consensus is that 3200MHz RAM is the sweet spot in terms of price-to-performance ratio. Up till that point you will see a decent performance bump for each increase in clock speed.See also

In general, we recommend at least 4GB of RAM and think that most users will do well with 8GB. Choose 16GB or more if you're a power user, if you run today's most demanding games and applications, or if you simply want to make sure you're covered for any future needs.

Generally speaking, you'll want to be running 3000MHz RAM or faster with the Ryzen 5 3600. Corsair's Vengeance LPX 16GB Kit is an excellent option for this CPU.
Corsair on Thursday released its fastest memory kit to date, the Vengeance LPX DDR4-4866, aimed at the most performance-hungry enthusiasts. The modules are specifically tested for compatibility AMD's Ryzen 3000/X570 platforms, though they can work with Intel-based PCs too.
The Infinity Fabric speed is directly linked to the speed of your RAM. So faster memory makes for a faster CPU. Ryzen is also picky about what RAM will run at what speeds. Here's the best list that I've seen and what you can expect from individual kits.
Intel CPUs also benefit (quite significantly) from faster ram. Ryzen 1xxx is harder to get to run with faster memory speeds and it depends a lot on the specific kind of RAM - people would have to make sure they got Samsung B-die which was more likely to work at higher speed.
RAM speed also becomes more important when targeting high refresh rates, alongside CPU speed, so the uptake of 144Hz monitors has also heightened the importance of fast RAM. Fast forward to 2019 and third-gen Ryzen, and RAM is in a good spot.
Faster ram pushes more performance from ryzen. Its as simple as that. In some scenarios the performance difference between 2400 & 3200mHz ram can be as much as 10%. Not a bottleneck per se , 2400mHz ram will work fine , you'll still get great performance but not 100% optimal.
Yes Ryzen benefits from it because the speed of the Infinity Fabric connecting the 2 dies runs at the speed of the memory. For gaming it will be somewhat noticeable, for anything else it won't be.
RAM speed does matter. It's moderately important with an Intel CPU, but actually very important with a Ryzen CPU.
Depends on what CPU you have, on the intel side of things you will not need as high speed ram as on the ryzen side of things. 2666mhz 8gb will be great to game, you will not need 16gb becasue games rarely use more than 8gb of ram.
Overclocking RAM Isn't Scary
With memory, they don't produce much heat at all, so it's quite safe. Even on unstable overclocks, the worst that happens is you'll get an error when testing for stability and be kicked back to the drawing board.B450 will it be compatible with 3200Mhz ram? The motherboard will support 3200mhz yes, but you need to "overclock" to get your RAM to 3200mhz (All you need to do is enable XMP, no need to actually overclock anything).
You can use memory modules of different speeds as long as they are faster than those specified for your computer. It is recommended to use modules of the same speed as those already installed in your system. If you do mix speeds, the modules will all run at the speed of your slowest modules.
Well, Ryzen doesn't support quad-channel ram. You can use 4 stick, but it only operates in dual channel.
CL means cas latency, it tells you how many clock cycles it takes for a certain piece of data to be available after the memory controller requested it from the RAM.
Is 32GB overkill? In general, yes. The only real reason an average user would need 32GB is for future proofing. As far as just simply gaming goes, 16GB is plenty, and really, you can get by just fine with 8GB.
It has been noted that 3200MHz CL14 is theoretically the fastest memory timings for Ryzen Zen 2 compared to 3600MHz CL17 and 3733MHz CL17 on paper, but the recent test at HardwareLuxx goes against this – or at least for the Ryzen 7 3700X. The best 3200MHz CL14 B Die Memory Kit for Ryzen 3000 we recommend is the G.
