The "series" is more of a cosmetic thing, a way to organise the sale of multiple CPUs and making it easier to view without having multiple sale tabs on.

Before I get into the main part of my comment, I would like to say you did a really good job at creating this game. I know you probably took most of the inspiration from Game Dev Tycoon, which is completely fine.
Here are a few things that you should do in the later future:
1. When I think of Hardware, I think of Mobile Phones, Tablets, Computers, Laptops, etc. If you are taking most of the influence from Game Dev Tycoon, implementing these Hardwares into the game should be a must. If you ever played Game Dev Tycoon, and I presume you have, you probably played the late game when the Hardware Lab was introduced and you could make your own game console. Use that similar architecture in this game.
2. Allow the production of laptop and mobile components and the ability to use other company's hardware in your own product.
3. Similar to Game Dev Tycoon, have the popups indicating historical releases of processors or other hardware.
4. Simulated Market?
5. Each Hardware you produce and sell should be stopped only when you want it to be stopped. Also 'Sequel' products should also be a thing. The ability to increase or decrease premium even when it's out in the public.
That's all I got for now. Hope you do some or most of these things in the future.
And again, what a great game!
