Why can’t CPUs merge cores?

1.05K views

So this is probably really stupid, but why, for a company such as AMD, cant they make a CPU similar to the 3970x but with 8 or so big cores with improved performance? I keep seeing insane core counts from them, but I don’t quite get why they can’t make really good single-core performance.

If one has a big house and multiple cabinets and kitchen appliances but only one person (thread) then that takes time to process serially in length versus a team of people (multiple threads).

A small house and kitchen cannot fit many people walking about either, which goes to the physical traces of people routing to needed parts of the house.

Then there is the agreed layout and remembered organization of tools and ingredient access (data storage and memory addressing). If there is any conflict of calls or needed slowdown to translate, this adds time to resolve for performance access of a timely manner.

In short, this is a balance of the intended output of a quick bachelor meal or a banquet for a large family gathering. Larger houses can process more at the cost of energy and heat with the space and usage.

To merge cores would require to decide what appliances and house layout to keep for optimal energy use with little uncomfortable heat for the people that walk about the area and this is given the output intended (a simple dedicated meal versus an excessive large buffet of varying side dishes).
