This is actually intresting. Got me wonding what are the differnces?

This was about the only thing I could find:
http://www.ask.com/wiki/Multigate_device

Both seem to be "nonplanar" (not flat as a pancake or 2D)


Found pictures too... from what I can make out:


FinFET:
ts


More surface area for a single drain+source? (depends on how thick the fin is?).



Tri-Gate Transistors:
ts



Multiple drains + souces (more surface area depands on how many source/drains there are).






^All of above is just my speculation, I dont actually know any of this stuff, its just from looking at the pictures.

Would be cool if someone that knew more about the matter chimmed in, with some info on the differnces between FinFET and Tri-Gate.

So hypothetical future:



Remainder of 2012: AMD's answer????
You may have found the reason they fired their CEO. Can't tell me each company doesn't have a real good idea what the other is doing and will be doing.

Wow Intel is really on a roll......

I am glad they aren't slowing down the releases due to lack of competition. Hopefully they keep prices fair.

The question is..... How does FinFET compair to Tri-Gate?

Is either one Superior in some way? ei. does Intel use less power than FinFET?
Does FinFET allow for faster speeds compaired to Tri-gate? Does FinFET take up less space?


When will TSMC and Glofo have "FinFET"?




So hypothetical future:

Present Day: Sandy Bridge 2500k chips = best bang for the buck

June 2011: Bulldozer unveiled, AMD re-takes best bang for the buck crown with chips slightly cheaper than 2500k SB and on performance with 2600k SB. Bulldozer also re-takes performance crown with their high end BD chip (but at a price).

2nd Half 2011: Sandy Bridge-E unveiled. Performance crown back to Intel or about even with BD (but at a price).

1Q 2012: Ivy Bridge unveiled. 22nm process and 3D transistors = ~37% increase in performance, Intel releases mainstream versions at same price points as SB, AMD no longer best bang for buck. Higher end IB chips also unveiled, performance crown squarely back to Intel.

Remainder of 2012: AMD's answer????



^ That is almost certain to come to pass.

Obviously the "AMD answear?" a Bulldozer version with FinFET.... however thats up to TSMC and GLOFO.

Intel is always ahead with its fabs tech, which is one of the reasons they have 80% of the market share.

See my edit above. I think the difference is FinFET transfers power along the sides of the fin and Tri-Gate transfers top and sides. Probably wrong, but had to try.

Thats how I was readying it also . But as always Intel throws a wrench into the works with the video . By showing the Notebook , desktop and SERVER chip . Server chips appear to be ready for production . Interesting.

My household has a E8400 box and a i5-750 box. I was looking at SND or BD for an upgrade to the E8400 box this year, but I'm thinking that I need to see first what kind of gains we see from IVB come next year.

If the gains aren't that big, then I can probably go with a slower but at that point in time, a far cheaper BD system.

If IVB is as good as intel is trying to make it out to be, then I might be building a new IVB box in about 1 year from now.

The i5-750 box would go to my wife :D

Im kinda convinced now that a 22nm Atom chip, could probably go into a smart phone.


If AMD can make a 40nm non tri-gate, C-50 and make it only use 5watts.
Intel can probably make a 22nm with tri-gate, C-50 ish CPU/GPU combo ~1watt or so.


Glofo's 20nm (22nm-equivalent) and hence FinFET isn't until late 2013.


2012 is gonna SUCK for AMD.... 2011 looks to be really good though.

Intel wants to play in the ARM market . Atom on 22nm should be interesting

1W is still too much, unless Intel also develops an awesome new battery technology to go with their new 22nm process.

Really have you seen AMD benchmarks? Going off of 1st qt results I don't think so. If intel was worried about AMD they wouldn't have moved 22nm back to first qt 2012

I think it is telling that AMD hasn't let anything out and Intel is showing working units for the next generation. I just don't see anything major from AMD coming soon, competitive, yes, mindblowing, no.

I don't think BD will be that good. The best I hope for is equal single-threaded performance to nehalem and throughput exceeding Gulftown. All in all I think it's gonna be akin to choosing between gulftown and sandybridge. Better multi-threaded performance or single- threaded. I think SB-E is going to walk all over BD.

The 37% increase in performance if translates to clocks kinda takes the fun out of debating IB clocks speeds. That should put IB at about 4.30ghz at stock clocks without turbo

I have kind of felt that way too, until this anouncement of Ivy Bridge today. Now I think BD will be much better than I thought and may even take the overall performance crown. If Intel didn't announce their tri-gate 22nm process and promise working IB parts in a few weeks, I would still be very sceptical. Now, I think BD will be better than my humble expectations.

This 3D fad is getting old...

:)

It's not as bad as the "X" fad in the late 90s / early 2000s.

My favorite so far is the Crest "3D" Whitening. What a pointlessly named product. I hope this "3D" thing dries up soon.

Well as the AMD guys say these chips are already fast enough we don't need faster chips LOL. So even if BD was great . It would be WAY WAY to expensive to buy an amd product on outdated process.

I hope you're right, we really need competitive AMD again.

Whys that? its a 3D chip. and pretty much sumes up its design in its name. Planar sounds better to you some how .
