With no onboard graphics you are required to buy a graphics card. That can raise your cost a significant amount if you weren't planning on buying one. If it ever dies, and every build I've owned has had the GPU die at some point, your computer is unusable until you buy another. Plus you can't do any Android development unless you boot into Linux. I'm sure these issues don't affect most people, and probably saves some gamers a little money that they can put toward their GPU, but I had two similar builds for the same price, picked AMD Ryzen over Intel to support the underdog and I regret it. I'm planning to give my Ryzen build to my folks and buy an Intel.

Getting a CPU with GPU is actually something I try to avoid. I don't want or need it, as I use 3d software primarily. It's a complete waste for me. So, as you can see this argument depends on the needs of the user. I have avoided buying a CPU with built in GPU so far, glad AMD is this way, I am converted.

Wow. I did not know about the Linux/Android development thing. Just looked it up. That is so weird.

I'm about to build a Ryzen system. I run Linux and I don't do any Android development, so neither of those affect me. Still, that is a weird limitation.

There are APUs for the Ryzen Platform and IIRC Ryzens latest have GPUs.

you regret buying a ryzen because you had to buy a gpu, and why can't you do any android development? can you not use genymotion or a real device for development?

No, but I am saying that should factor into the cost. If I buy a CPU with similar performance to Intel for $20 less but have to buy a graphics card for $50, it's not really cheaper. The regret is just the difference between being able to do everything and having to work around it because my CPU isn't supported. I doubt there's anything you can run on an AMD chip that you can't run on Intel but the opposite isn't true.
