ive never gotten around to watching youtube videos or anything but i would like to know any major differences between them
to summarize things simplistically, which is about how I understand it anyway...
Ryzen 3rd gen processors have slightly better IPC and higher core counts with even low-end processors including SMT, AMD's term for hyperthreading.
Intel processors can overclock to higher clock speeds, which overcomes IPC defecits. But you have to buy high-end to properly exploit the potential; high-end processors, e.g., 9900K, 9700K, high-end overclockable motherboards for correct chipsets and powerful VRM's, and high-end (closed loop) cooling.
In the end, Intel's very top-end processors still enjoy slight gaming advantages when overclocked (that includes 9900KS and other factory-overclocked variants and refreshes), usually when gaming at low enough resolution where the GPU is not the bottleneck. But for productivity/content creation apps that like processing threads you can find cheaper processor/motherboard/memory combinations with AMD that outperforms (many times far outperforms) Intel's offerings at any price point or market segment.
With pricing where it is now Intel's low and mid-range processors (I3's and I5's) are largely irrelevant in the market today when compared on price/performance basis. Many would argue so are the high-end (I9's), except when even 1fps makes the difference and cost is no object to achieving that.
But to answer 'which is better...' is a lot more difficult. I suppose I'd say Intel's are better because they've had a lot more opportunities to get the most out of 14nm. But if the newer and more efficient process is better that has to go to AMD/TSMC and the 7nm process used on the Zen2 CPU dies. If you're limited to buying from a well established pre-built mfr, e.g. Dell, HP, Lenovo, you'll probably find Intel is better if simply because they don't offer a proper range of AMD alternatives. It's really hard to define what 'better' means to someone else as it's so personal.
EDIT add: and oh yeah...you'll also find Intel is better when used in various scientific, engineering and mathematics applications that were compiled to benefit Intel processors, e.g., MatLab. There aren't all that many and so are properly considered edge-use cases, but if yours happens to be one you'll appreciate knowing so. You'll have to ask very specifically in the support forums for that app. to find out.
