GlobalFoundries – Expanding to Meet Demand

It’s been about a year since we last had a serious discussion with GlobalFoundries. Last CES, they were relatively recently separated from AMD and we didn’t have a whole lot to report; 12 months later, there’s a lot more going on. They are now doing full production of 45nm and 40nm chips, the latter going into many of the other electronics devices we use on a regular basis. Where AMD and Intel have lived on the 65nm, 45nm, and now 32nm nodes, most of the other IP developments are happening on the so-called half-nodes. Smartphones and their related technologies are the big one, and GF is working with many of the major players—Qualcomm, ST, ARM, and others. GlobalFoundries now has 300mm fabs in Germany, New York, and Singapore with additional 200mm fabs in Singapore; all told there are 12 locations with approximately 10,000 employees.

One of the big questions last year was how GlobalFoundries would handle the needs of other fabless semiconductor companies. The acquisition of Chartered Semiconductor increased their presence in a big way, also giving GF fabrication facilities in Singapore. While AMD continues to use nearly all of the 45nm capacity, the 40nm production has a long list of partners. The Dresden fab 1 is adding capacity and they’re pushing up to 80,000 wafers per month. The upstate New York fab 8 construction continues to progress, and demand for their services is great enough that GF has already begun working to expand the facility before the current construction is even complete! Fab 8 should come online in 2013, with production focused on 22/20nm output and capacity for around 60,000 wafers per month.

Right now, GlobalFoundries is entering full production mode for 32nm, with AMD’s Llano chips scheduled to be the first market solution to use the process. Later this year, AMD will also launch their Bulldozer cores on the 32nm process. In a similar vein, the 28nm node uses the same gate stack and will leverage the learning of their x86/32nm ramp. Qualification and production of 28nm will continue over the coming year, with plenty of new 28nm devices to come. One of the interesting points GF brought up is that in the past, doing test SRAM wafers has been the common practice for ironing out the glitches in a new process. SRAM wafers produce regular grids where errors are easy to detect; the problem is that complex logic stresses the latest process technology in a different way. To further help with process refinements, GF also runs a test SoC ARM Cortex A9 microprocessor design through the pipeline. The results of this test wafer not only help them find and fix problems, but they also give a better idea of how chips on the new process perform. The following slide summarizes what they’ve seen so far.

Bumping typical clock speeds from 1.5 to 2.0GHz for the lower power designs, and from 2.0 to 2.5GHz on higher performance chips is good, but even more importantly GF saw power requirements drop up to 30%. Providing 25-33% more performance using 30% less power (and a 100% increase in standby battery life) will be key to enabling the next generation of mobile devices, and we should continue to see a roughly two-fold improvement in performance at a given power envelope every couple of years. Over the course of the year we should see a major transition from 45nm to 32nm for AMD solutions, while the other devices should experience a similar transition from 40nm to 28nm.

GF looks to be doing well, and they are looking like a viable alternative to TSMC for companies looking for fabrication facilities. They have technologies ready for all the electronics segments, from CPUs and microprocessors to smartphones and DTV. They’re also looking at opportunities in the MEMS (Micro Electro Mechanical Systems, i.e. DLP, optical switches) and 3D stacking. Over the next two years, they should more than double their 300mm wafer capacity, and continue R&D into future technologies.

Moving beyond 32nm and 28nm, GlobalFoundries is well into the research and design phase on their 22nm and 20nm nodes. We asked about plans beyond 20nm, and GF says that the current planar transistor commonly used in today’s microprocessors should still be good for a few years. After that, they expect the next five or so generations of process refinements to move to more of a vertical arrangement for the transistor layout. Every so often the naysayers inevitably rear up and claim we’re reaching the end of what we can achieve with semiconductor technology. First it was getting below 1 micron, but we’ve long since smashed that barrier and are moving steadily towards the 1nm mark. How small can we go? No one is willing to call it quits yet at GF, and we expect to see additional creative solutions as we run into technological hurdles.

    Looks like you re arguing with an Intel employee,
    though AMD are quite messy with their PR job.
    Anyway, BD is sheduled for somewhere in april
    with Llano following in Q3 according to the few
    available official and leaked infos.

    Enough with the "Intel employee" garbage, please. I spent upwards of three hours in meetings with AMD at CES; I didn't even visit with Intel.

    As mentioned, AMD is entering their "quiet time" before the yearly earnings report, so they are not allowed to discuss products that aren't shipping in any sort of detail. The fact is, I asked about a dozen times in varying ways for more information on Llano and Bulldozer, and they cannot (legally) provide me with the details I'd like. Too bad for us. Most of the leaks you're referring to are now outdated, so other than AMD telling me "within a month of each other" (and they didn't tell me which would come first), we really don't know what's going on right now.

    Which will come out first: Llano or Bulldozer? It really doesn't matter that much. Both will release close to each other, and personally I think Llano would be the better chip to ship first. Imagine what Llano reviews will be if BD ships first (and lives up to the hype): "Well, Llano has some pretty sweet integrated graphics, but we can only wonder what it would have been like when paired with Bulldozer."

    The two products are also very different markets, and for some people Llano is the more exciting offering. Imagine HD 5650 performance from an IGP! If AMD can get the updated K10.5 power requirements down to Core i3/i5/i7 levels, that's enough to win a lot of important benchmarks. My biggest concern with Llano is that K10.5 in the past has been okay performance with pretty terrible battery life relative to Intel--we're talking Core 2 levels of performance but at the cost of higher power in many situations.

    If Llano has a lot of new power gating enhancements thrown in (relative to Athlon/Turion/Phenom II), that would really change it's potential. Sandy Bridge quad-core got 10.24W of average power draw during our Internet battery life benchmark with a 17.3" LCD. To put that in perspective, the AMD Phenom II P920 used roughly 15.3W of power in the same test, with a 15.6" LCD (and a paltry 1.6GHz maximum clock). So yeah, we'll see what happens probably in the next six months.

    Troll alert.

    Sorry, someone had to say it. May as well be me.

    "Brazos is even smaller than Atom, in part thanks to the use of 32nm (Brazos) vs. 45nm (Atom)"

    While 40nm TSMC process has even better density than Intel's 32nm process. The naming stands.

    Fixed. Sorry for the confusion; it's been a couple long days. Reply

    "Providing 25-33% more performance using 30% less power (and 100% less standby power)..."

    100% increase in standby battery life != 100% less standby power.

    Llano is a failed bulldozer. Reply
  • silverblue - Sunday, January 9, 2011 - link

    It's nothing of the sort. It's not even targeted at the same market as Bulldozer.

    Troll alert #2.

    i dont get brazos. lame cpu paired with lame dx11gpu. how exciting. at least with intel you got a GREAT cpu paried with the lame-st- gpu. simply put, the integrated gpu of amd needs to be GREAT . at least > 5770 levels of performance for me to even care. so yea, triple core brazos > no nerfed dual core + integrated no nerfed gpu.

    If you don't "get" Brazos then I suggest you go back and read all the articles that mention Ontario and Zacate, and concentrate on what their targeted market is. Reply
