Tri-gate transistors?

[5005]

Hey,

I had another question about Intel CPUs!

What are the advantages of tri-gate transistors? It's a proprietary thing for Intel right?

I saw it on this comparison. Does this explain why Intel processors always have lower TDPs than AMD? And are more power efficient?

Thanks in advance

Clearly faster CPU clock speed
8 x 4 GHz
vs
4 x 3.5 GHz
2.29x faster CPU clock speed

*facepalm*

This would be good reading for you

You probably already know this, but comparison sites like that are only good for a very high-level view of differences between processors, and usually it's only accurate if it's between two of the same family (ivy bridge vs. ivy bridge, etc). Comparing things like clock speeds between AMD and intel has never been accurate due to differences in architecture and the resultant instructions per cycle.

Dang If its that fast Ill have to sell my 4930k for one of those AMD's bad boys

The biggest advantage comes at low frequencies. And this advantage is lower power at low frequencies.

OP: what kind of gorilla math is that?

----

The biggest advantages of Tri-Gate (called FinFET by others) are that it significantly lowers leakage and enables smaller gate geometries. It's why all foundries are switching to FinFET at the 16nm node.

The way it works out is significantly lower power while running at lower frequencies, but also allows higher frequencies at the same power level.

Tri-Gate is Intel's implementation of a multi-gate transistor. Others call it FinFET, which is similar but not quite the same.

Pretty confusing but that explained a lot, thanks
