Dan - just a few things.
D1BR - 200,000 sq. ft. (once development, now production)
I don't know what you mean by D1BR, but this has not been mentioned on any of the pages that I saw on Intel's site. There was a fab called D1B, but it was renamed to Fab20 when it became a production fab. Therefore, you can't count it twice.
D1C - 135,000 sq. ft. [.13 -> .10]
I found a link in my previous post that had the cleanroom size labeled as 120,000 sq ft. The link is from Intel, so I would consider it more reliable.
D1D - 175,000 sq. ft. (not built out) I agree.
D2 - 36,000 sq. ft. in 1991 [.18/.13] flash
It's probably larger than 36,000 sq ft now. The capacity, though, is .18u flash and .13u logic. The link I found was sure to specify.
RP1 - 56,000 sq. ft.
It might be worth mentioning that this is purely a research facility. I don't think Intel intends it to be a production fab in the near future.
FAB1 - closed? I agree
FAB2 - closed? I agree
FAB4 - replaced on site, probably D1D
D1D is being built completely new. I don't think Fab4 exists any longer.
FAB5 - closed?
According to one of my previous links, Intel connected Fab5 with Fab15, and now calls them a single fab.
FAB6 - closed? I agree.
FAB7 - 435,000 sq. ft. closing next year [.35] flash
I think your link is quite mistaken about the size of the clean room on this one - and I think I know why. I saw one link that mentioned Fab7, and then shortly afterward, said that Intel would increase cleanroom space by more than 400,000 sq ft. However, in the context with the rest of the paragraph, you realize that Intel was talking about the combined space of several new facilities - not just Fab7. Fab7 by itself is much smaller, but the link didn't go into specifics.
FAB8 - ? [.35 and above] I agree.
FAB9 - Closed? flash
I think it might still be opened, but it's probably combined under the title of another fab (much like Fab5 is now part of Fab15).
FAB10 - 90,000 sq. ft.? [.25/.18]
Fab10 and Fab14 together combine to create 90,000 sq ft of cleanroom. You can't count them twice.
FAB11 - 120,000 sq. ft.? [.18 -> .13] flash
Fab11 is both flash and logic - and none of it is .13u, according to the links I saw. I have also not heard any press releases suggest another .13u fab.
FAB11x - 135,000 sq. ft. [.13] I agree.
FAB12 - 135,000 sq. ft. [.18] I agree.
FAB14 - 90,000 sq. ft. [.25/.18]
Like I said, you can't count this, and Fab10 together.
FAB15 - 120,000? [.35/25] -> [.18/.13] flash
It does not appear that this fab has commenced .13u production. The links that I gave should be recent as of earlier this year, and they did not even mention .18u production.
FAB16 - On Hold I agree.
FAB17 - 95,000 sq. ft. [.13]
I'm sure some of this fab is still producing things at larger geometries. Intel acquired this fab from Digital Equipment Corp, and I think Intel still has contracts that they outsource out on it - thus the strange .28u listed capacity.
FAB18 - 80,000 sq. ft. [.18] I agree.
FAB20 - 120,000? [.13]
I am not familiar with the size of this fab. I have been told that it is smaller than D1C, though.
FAB23 - 120,000 sq. ft. [.18] flash I agree.
FAB22 - 133,000 sq. ft. [.13] I agree.
FAB24 - 135,000 sq. ft. - on hold? I agree.
Based on my previous figures, I think that Intel's current production CPU fabs are Fab11, Fab12, Fab14, and Fab18 for .18u, and Fab17, Fab20, Fab22, and FabD2 for .13u.
Fab11 is partially flash and partially .25u (probably chipsets). If we estimate half of the fab goes towards production of .18u CPUs, that would mean ~60,000 sq ft, according to your guess of 120,000 sq ft, total.
Fab12 is all .18u logic, so it probably produces nearly all .18u CPUs. Therefore, that's 135,000 more sq ft.
Fab14 is partially .25u, and that's probably chipsets. .18u might be used for chipsets, too (aka Brookdale). Let's estimate that half of this fab produces .18u CPUs, which is 45,000 sq ft.
Fab18 is all .18u logic, so we might be able to estimate all 80,000 sq ft as going towards .18u CPUs.
Added up, that's 320,000 sq ft of space. The majority of Intel's CPUs (probably 75%) are built on .18u right now, including the large Pentium 4, and ultra-large Cascades and Merced dice.
Estimating .13u fab capacity is futile, since most of those fabs are new, and need to ramp up. FabD2 and Fab20 have been ramping since this past Summer, so they will be closer, but Fab17 and Fab22 have only just begun.
However, if we guess that 25% of Intel's CPUs are now .13u, and guess that Intel's .18u fab space is about 320,000 sq ft, that would bring Intel's total fab space to about 425,000 sq ft. You guessed AMD's fab space between 160,000 to 180,000 sq. ft. Given AMD's lower yields, it makes sense that Intel has about 2.5x more fab space, yet they can produce 4-5x as many CPUs.
Then again, most of these numbers had to be made-up, anyway, so I don't believe for a second that this is accurate. Still, it's fun using Dan3-Math to prove a point.
