This is correct from a logical point of view but not a practical point of view. With a few major exceptions transistors basically are one shape and do one thing. So if you can scale the process node you scale the density, if you scale the density you scale the performance. It’s not like 1 transistor could you give you 0.01 flops and another could give you 0.02 flops, a transistor does 1 thing and it works or doesn’t (with a few caveats), and the second order effects don’t really overcome that.
- sroussey 4y agoOh, transistors are not one shape across nodes. Not anymore, and not for a long time. The planar version taught in beginning EE classes has evolved into various complicated 3D shapes.
- SilverBirch 4y agoYeah I know, I was putting caveats all over the place because first order, things are simple, but there's lots of complication. But in reality density == performance, and transistors are mainly just interchangeable. Yes, you could theoretically get a less dense transistor with a fantastic slew rate or some such property, but it's very unlikely it'll matter in a conversation about digital logic.
