AMD 7nm fab vs Intel 14nm fab ?

[Turtle Rig]

What advantages are there to getting a 7nm amd fab compared to a Intel 14nm fab ?.  Thanks plenty in advance.

None, because it's a completely different architecture and can't be compared.

 

That's like asking if a small fork or large spoon is better.

Small fork because it can grip to things.

Nvm spork would be.

You might as well be asking "What's better, a large toilet or a small bathtub?"

 

They're somewhat similar, but completely different, and you can't compare.

You're asking us to compare something that isn't out yet and is unverified in performance to the current Intel platform. What answer do you really expect from this? Because nothing that anyone says is going to be reliable.

First of all..

It's not AMD's 7nm ... the factories belong to Global Foundries (which was owned by AMD but they sold their part and it's somewhat independent) and TSMC. The design of the whole thing was made by Samsung (the machines and stuff)

 

Also ... you can't put an equal sign between  Intel 14nm and tsmc 14nm and global foundries 14 nm

The numbers 7nm or 14nm are more of a " n nm class", which means most of the things in the chip are 7nm or around 7nm, or 14nm or around 14nm.

 

When AMD, TSMC, Global foundries says 14nm, they mean some structures inside the chip can be 14nm... but for example if a component in the chip is 14nm wide, it may have to be at least 20nm long, a limitation of the manufacturing process.

In the case of other components in the chip, let's say less used, it may not be possible to make them lower than 22-25nm in any direction.

 

Intel may have different rules for what it considers 14 nm ... for example they may be more honest and they may say 14nm for when they make structures that are 14 nm wide AND 12-14nm long, so basically BETTER than the alternative solutions.

 

Anyway... in general, the lower the nm number, the smaller the internal components in a chip can be, which mean all the components can be packed closer together in the chip so

* you can squeeze more components inside a chip in the same surface, or make the chip smaller using the same number of components

* smaller transistors and components inside the chip means these components need less power to do their job, so overall the chip consumes less power

* the distance between components inside the chip is smaller, which means there's less power required to push electrons between components... and this means less heat is produced to achieve same things

* also, less distance means there is potential to reach higher frequencies - with older bigger nm designs some things are simply not possible, because the chip waits a lot of time for electrons to move at the speed of light from one side of the chip to another .. speed of electricity is around 280 meters per nanosecond or around 0.01" per picosecond ...

 

... and there's other reasons...

You rock man,  thank you soo much for your detailed response.  I appreciate it greatly.
