While the payoff from HK+MG could run out for Intel in the next decade, with respect to just this year, it could be huge. Intel's director of operations for its Digital Enterprise Group, Steve Smith, told reporters to expect a range of five new products using 45-nm lithography to emerge from Intel in the second half of 2007, to be released for the desktop, mobile, and server segments probably the same way the company approached its successful Core 2 Duo rollout last summer, in the following categories:
- A dual-core notebook processor with a 35W power envelope
- A new dual-core/quad-core processor family for desktops
- A new dual-core/quad-core processor family for dual-processor servers
The exact sequence of introduction will depend on customers' readiness, Smith added. Later, he told reporters he cannot guarantee that every motherboard currently in production for Core 2 Duo and Core 2 Quad processors will support these new families, though it's possible that some may.
One performance improvement consumers should expect to see from the Penryn family is an old familiar one - something we were once told we might not be thinking about any more: higher clock speed.
"For Penryn, we're going to deliver some micro-architectural features that will improve performance, and separate from that and orthogonal to that, we're going to deliver some clock rate improvements," Intel's Smith told reporters. "You can expect some frequency increase within the same thermal envelopes; we know that is possible, and that's our plan for these."
Smith also confirmed that the new Penryn series will implement the long-anticipated fourth set of Streaming SIMD extensions to its instruction set - its next generation of single-instruction, multiple-data instructions that have steadily improved Intel CPUs' capability to manage multimedia and streaming data. "We already see those running in our lab successfully," he stated, "and what we're seeing is excellent, multiple-double-digit performance gains on media-type applications. So we're seeing the result we expected there from SSE4 in our initial evaluations."
"There are literally hundreds of material options for metal gate electrodes and high-k dielectrics, and identifying the high-k-plus-metal-gate material combination that meets all of these requirements - high performance, low leakage, reliability, and manufacturing requirements - is a very significant accomplishment," Intel's Mark Bohr noted. "No other company has reached this level of success, and they are not expected to have high-k-plus-metal-gate until the 32 nm generation or later."
Earlier this week, AMD confirmed it's looking to 2008 as the year it completes its 45 nm transition plans. If Bohr's prediction is correct, then at least for AMD, that old projection of finding the "Holy Grail" in 2010 could be just about right.
11:15 am January 27, 2007 - ...Or not. Saturday morning, the IBM Research Center, working on behalf of partners AMD, Sony, and Toshiba, announced it has also found a formula for both the high-k and metal gate compounds. "After more than ten years of effort," stated IBM vice president of science and technology, Dr. T.C. Chen, "we now have a way forward."
There will be some skirmish over who made the discovery first, though it will likely be tossed around in academic circles before being discarded, as well as being entirely ignored by the consumer. IBM's announcement means both AMD's 45-nm CPUs in 2008 and beyond, and future renditions of the Cell CPU jointly produced by IBM, Sony, and Toshiba, and currently in use in the PlayStation 3 console, will use HK+MG technology.
IBM also stated that implementation of the new material will be possible without a major retooling of existing fabrication facilities - an achievement also boasted by Intel on Friday morning. If fabs had to extensively retool in order to implement new processes, critical months could elapse while the CPU market would have to settle for existing inventory - this at a time when the industry doesn't like to measure inventory in units other than weeks. Intel's Mark Bohr told reporters that the added steps for his company's fabs to implement HK+MG may add just a few percentage points to fabrication costs, but the benefits will tremendously outweigh those costs.
Bohr also mentioned that Intel will begin using a process called atomic layer deposition (ALD) in its lithography processes, which will enable Intel to deposit materials layers as narrow as one atom thick, giving it greater control over the thickness of the gate oxide material. Intel did not invent ALD, so it's likely that IBM -- and, by virtue of their partnership, AMD -- will also utilize this or a very similar process in the coming months.

|Great article. Very informative.
One point. Intel is enthusiastic, not "enthused." Please. This is not a word.
Thanks.

|The verb enthuse is not well accepted. Its use in the sentence The majority leader enthused over his party's gains was rejected by 76 percent of the Usage Panel in the late 1960s, and its status remains unfavorable: the same sentence was rejected by 65 percent of the Usage Panel in 1997. This lack of enthusiasm for enthuse is often attributed to its status as a back-formation; such words often meet with disapproval on their first appearance and only gradually become accepted over time. But other back-formations such as diagnose (a back-formation from diagnosis that was first recorded in 1861) and donate (first cited in 1785 as a back-formation from donation) are considered unimpeachable English words. Since enthuse dates from 1827, something more significant may be overriding the erosion of popular resistance. Unlike enthusiasm, which denotes an internal emotional state, enthuse denotes either the external expression of emotion, as in She enthused over attending the awards ceremony, or the inducement of enthusiasm by an external source, as in He was so enthused about the diet pills that he agreed to provide a testimonial. Possibly, some people's distaste for this emphasis on external emotional display and manipulation is the source of unease that is manifested by a distaste for the word itself.

|Nice.. I liked the update at the end. So IBM wanted to keep the discovery as a secret for a little longer - no big deal. Besides, once the CPU's go to mass production, it's VERY easy to bribe some worker to steal one for reverse engineering the exact materials used.
I just wonder why there was no mention of octa-core CPUs. It seems the real revolution will be having all popular software rewritten for parallel processing and smarter use of idle CPU cycles (for background virus checking of EVERY file with LATEST defs, backup, compression, indexing, preloading fav websites while making sure content is fresh the moment u click on tab, pre-drawing latest emails you've received incl attachment-preplaying for ZERO wait-time - not even HD access, whatever). Just smarter use of already avail resources, that's all...

I know about IBM horning in on everything patentable ala "Copper bottom" chips, etc. to support their almost totally misleading ad campaigns. As for reverse engineering the Intel "mystery metal" ... there is not eough time left in my life to re-invent someone elses wheel.
" ... there was no mention of octa-core CPUs ...(?)"
As for the transitions to high numbered CPU cores on a single die, the jump would be from quad-core (4 processors) to hexidecimal-core (16 processors) or hexi-core(?) The math works better, the traces match more easily to the individual PUs ... as does the gross topography, the core layout on the die and die layout on the board(s). The next "multi-core level" after that is to 64 processor units, which has all manner of thermal questions like hot areas on the die, etc. (The prefered gross, macro topography for multiple hexi-core PUs will be a round computing device about the size of a coffee can with hexi-core "blades" feeding a central, axial glass bus ... my next paper/article will explain the details. Copyrights & patents are non-IBM.)

|So if the jump is from 4 to 16, that probably means we won't be able to buy those 16-core CPUs in the next 3 years or so? Just cuz the jump is that high? And that is why there was no mention of the "next" multi-core CPU ver?
BTW re the re-inventing the wheel - well, if someone else's intel about wheels can make your wheels go 10% faster, you'd use that knowledge even in 2 years WHILE continuing work on your own wheel using your existing tools and knowledge. The race, after all, is a long term race.

|To do all that, we'll still probably have to wait for common RAM configurations to be in the double digit gigabyte range.

|Actually, I think hexicore would be six, and I think 8-core processors will be next. You are assuming they are going to be going by square powers of 2, when they could go by square and have 9, like the Cell; or they could just go by powers of 2 like their current quad core. IIRC, the Core Quad is just two Core Duos( i.e. a dual-dual core), not a "pure" quad core.

|Its true however..... The chips are completely different. If you look at say a 486dx133 (133 Mhz CPU) and a 90Mhz Pentium 1 its the pentium destroys it. Mhz and Ghz isnt the only thing that makes a chip better or faster.
The more Ghz you have the hotter the chip is going to run. You get at a 5 ghz chip you better have a air conditioner ontop of your chip or its going to smoke the moment you turn the computer on.

|After you pass 3 GHz you begin to get diminishing returns. The whole reason that Intel has stopped stressing names like "Pentium 4 3.06 Ghz" is because people get the impression that frequency is everything. That is why AMD always used numbers other then frequency to identify their products.

|So we go all the way to the atom.
Then I guess we just keep increasing clock speeds and researching parallel processing?
If the speed of light is as fast as you can go and
electricity flows at that speed, then this is an issue of switching frequency rather than speed of source.
Of course, for the average Windows user, the machines are getting so fast that new and old are hard to tell apart. The rushes of speed we used to feel a decade ago aren't happening anymore for me.

|This should not affect AMD, the way I read it it's just a different manufacturing proccess, will it realy allow them to make a better cpu cheaper... I dont use intel cause of price.. so as long as AMD can make a cheap CPU for endusers they'll alway's sell cpu's to the consumer market who dont need a 8ghz CPU!

I have started a thread/topic at DIYAudio.com to try to discover the identity of the Mystery Metal. My guess is it is Silver or a Silver alloy like Sterling Silver (90% Silver/8% Copper). I would bet as well that following metals commodity prices would likewise give additional clues at to the Mystery Metal ID.

|AMD ran into the same wall intel did--they were basking in the sun because their technology bested the competition. Well, if they had anticipated this Intel comeback earlier, they would have been scrambling to get new enhancements rather than selling buttloads of current technology cpus.
AMD learned the hard way, but honestly it may be too late for them. Intel's not taking their current lead for granted and is speeding through innovative designs despite their lead this time, something AMD needed to do a year ago. Problem is AMD does not have the nearly unlimited resources to make a huge comeback like Intel did. If Intel keeps up the pace, they will certainly spell certain death for AMD, though the death of AMD may not occurr for many years to come.

|AMD has been around since 1969 and making chips for the PC since the 8086, I really don't see them dying. Even if they don't take the lead again any time soon there is room for more than one player in the CPU business (not to mention they just bought ATI). Look at VIA, practically no one uses their processors and they're still making them. AMD has a very strong following of fans, they'll be back in the lead again eventually. This is coming from an Intel fan by the way.

|Fair questions. There are some unanswered questions at this point: We don't know what the new clock speeds will be, probably because tests on how much the accelerator pedal can be pushed have not been run yet. Intel's CPU tests were only conducted in the past few days; we do know a Penryn design can run Vista, Mac OS X, and Linux (don't know what distro).
How much would these chips cost? Earlier in the week, during Intel's conference call and before the materials discovery announcement, Intel's executives said their goal was to introduce the 45 nm generation at about the same price point as the 65 nm generation. My feeling is, that price point will elevate just a bit - chock that up to inflation.
I should add: Some of the real estate savings that Intel will gain by cutting the transistor size in half, will likely be partly consumed by an expanded L2 cache.
When? Intel has already announced its intention to begin production of Penryn chips in time for introduction to the mass market in the second half of 2007. So essentially now. There's not going to be a five-minute rest while these guys are getting retooled. Now, AMD has been working to phase in its 65 nm generation, and that job will be finished this year. But with IBM's announcement (see the update) that it's found an HK+MG formula as well, and it'll share that with AMD and the STI coalition (Cell), then we'll see HK+MG chips from AMD probably a year after Intel's - not 2010 as Intel's Mark Bohr was hoping.
