Very nice, unfortunateley it's not a question of having a good CPU architecture, but to a much larger degree a marketing question. I don't doubt that AMD can design a good K8 chip, but in order to do that, they first have to make the K7 a success. They are pretty strapped for cash and unless they can stop bleeding red ink, they might not even be around long enough to see the introduction of the K8. So they can design decent CPUs. This is good, but hardly news. In the past they had good chip designs falter due to manufacturing problems. Lets hope they can ramp up K7 production fast enough so they have a product to sell.
Having said that with a light undertone of sarcasm, I should probably note that I am/was a satisfied AMD customer. I wish them well because Intel deserves some competition, but they need to be careful not to repeat past mistakes. They have to become profitable soon, which is no easy task when you face a giant like Intel.

The first is to build an IA-32 x86 chip and then add a mode that extends the x86 ISA with 64 bit registers, integer and logical operations, and flat addressing ("64 bit x86").
The alternative is to build a bilingual CPU that can execute both IA-32/x86 in one mode and a 64 bit ISA in another. There is really only one choice for the latter that makes sense - Alpha. AMD already licenses EV6 interface technology from Compaq and an Alpha ISA license would be an extension of it. It couldn't be Intel's IA-64 for two simple reasons: 1) details of IA-64 are only gradually entering the public domain, and 2) Intel has many aspects of IA-64 patented and cloning it would be like entering an infinitely deep legal minefield.
I suspect the K8 is the former, a 64 bit extended x86 although the apps and os software availability problems seem formidable. M$ has its hands full with x86 and now IA-64 versions of windoze and there already is an ideal 64 bit ISA to run Linux on - Alpha

On top of that, they are selling! AMD beat Intel in retail sales for a quarter! Big guys like Compaq, Gateway, and Intel are selling them in their systems!

AMD's specific financial problems (Score:3)
1) AMD's sixth generation processor design was put together decently, but with a very shallow pipeline. This means that with your typical ramping schema, it should be at about the same MHz level as the Cyrix chips (300MHz) or the WinChips (250MHz). As it is, AMD has an immensely aggressive ramping team which has managed to bring AMD's K6 family to just under Intel's P6 family in MHz, which has a couple effects:
(a) Because the K6 family has been historically about two clock bins lower than the P6 family, and because Intel's pricing schema involves tremendous gulfs between the top two clock bins and all below it, AMD's cpu Average Selling Prices could not help but drop lower and lower as time progressed.
(b) Due to the K6's low pipeline and the fab team's uncomparable (and absolutely necessary) aggressiveness, the bin split of the K6 family parts are HORRENDOUS. Before AMD's recent jump to their cs44e7 hybrid process (quarter micron with some 180nm features), the top bin being produced was 475MHz and the bottom bin was still way down at 333MHz or so, with over half the parts still binning below 400MHz. This added more shame to their ASPs, as anything below 400MHz was under a hundred bucks, which means something like only fifty dollars profit per chip, at best.
(c) As a result of the aggressive ramping they needed (to compete with Intel's more easily rampable design), yields were kept lower than comparable Intel parts (though for the most part not horrendous, save for the little "incident" in February). This means that they get lower quantity to sell than they could have gotten otherwise, which means that, in addition to ASPs, they're making very low amounts of revenue.
2) There really is no way to get past problem 1a without making a newer cpu core with a deeper instruction pipeline. And to get past the problem in 1b, while that newer cpu core will help, it'd really be the wiser choice to expand your capacity, so AMD has forced themselves to spend a whopping, Intel-like amount of money (in R&D and in building a whole new megafab) so that, while they hurt in current quarters, they can thrive in future quarters. Would this strategy work? It's not guaranteed, but it's a hell of a lot cooler than the old "play it safe" mentality. If AMD had played it safe and not done all this fab or R&D stuff, then they'd have easily made profits (I believe) off the K6 series in every quarter of 1998 and 1999. The only problem is that they'd be lagging in clock speed at this point and they'd have no real future technology with which to compete. In effect, though they'd be profiting, they would be writing their own tombstone. The way they're doing it now, they've lost lots of money but they *finally* have superior technology to work with. Even without that newer fab, as soon as they ramp K7 to at least 60% capacity, they'd be making a pretty solid profit. With the newer fab, they'll be able to profit very nicely and retroactively fund these projects that they so unharmoniously dumped cash into all these years. They'd also be able to afford their future plans, which is a nice byproduct.

I would agree about 64-bit x86 being an abomination (and I think it would be a marketing flop as well). I don't, however, think that splitting the market with an Alpha variant would be successful for AMD either. If for no other reason than I doubt that AMD could do much differently in getting long-term cooperation from Microsoft for an Alpha derived architecture than Compaq did.
Not only do I think that the abandonment of the desktop and server MPU market by AMD would be disasterous for the industry (competition for Intel has been a very good thing for consumers and system vendors), I think it would be disasterous in the long run for AMD, as it would permanently relegate them to being only a niche player. I think AMD's only option in the long run is to take Intel on directly with an IA-64 clone. There are ways of getting around the patent issues, although they certainly won't be easy and probably not cheap either. There are a lot of features of the current and previous generations of x86 designs that are the subjects of patents, and it hasn't stopped companies from building clones (AMD, Cyrix and IDT).
It may at some point become not so advantageous for Intel to have all of the clone chip builders drop out of the market, as it could start or re-start a move against them on anti-trust grounds. There are other ways that having a certain amount of healthy competition is good for a company too.

You are making the very common mistake of comparing production parts to prototype parts. The 700 and 733 Coppermines are PRODUCTION. Intel has managed to fab them at high yields, and they are bug free.
The 900 Mhz and 1 GHz K7 parts are PROTOTYPES. They may have various bugs, and they are probably not able to fab them at high yields. They may get one or two working parts per die. They are NOT parts which are ready for production and are NOT parts which can be fabbed in quantity.
I have no doubt that Intel is testing parts at those frequencies also (they demoed a 1 GHz Coppermine at the beginning of the year). Intel is a very private company and doesn't announce their parts until they are ready for production, so you don't hear about them until they are ready for production.
Also, your comment about K7 being 0.25 is wrong: the shipping K7 uses a hybrid 0.18/0.25 process, where the transistors are 0.18 and the lines are 0.25. This means the full 0.18 shrink of K7 will have a much lower boost than a full 0.25 to 0.18 transition (e.g. Katmai -> Coppermine). AMD advertises it as 0.25, probably to mislead people into thinking that the 0.18 shrink is going to gain them so much, and that the current part is just a preview.
Third, while Coppermine is debuting at only 700/733 those are the first parts. K7 debuted at 500/550/600 but that doesn't mean only those parts will be available for the future.

This is largely due to the pre-announcement effect: everybody heard about K7 and delays purchases of AMD chips(when they would have bought a K6).
Now they announce the K8 when the K7 is barely ready for production. This is going to have the same effect. Consumers are going to say, "Why should I buy K7 now when K8 is coming out Really Soon Now?" They'll probably just buy Intel.
Willamette/Foster will be out by the time K8 is. What has the world heard about that? Very little. Almost no details have been made public.
Intel never makes the details of a processor public to the industry until it it ready for VOLUME production. Often their published figures are lower than expected, so the compeititors feel comfortable and slack off, then they grab the crown from out of nowhere (P6 is the prime example, and Willlamette/Foster will do the same).
This is the reason Intel is more successful than AMD - they don't preannounce, so they can sell chips they can fab in volume NOW, and not tell customers "don't buy what we have now just wait a little while longer and we'll have this whiz-bang part" (OK, they didn't do this with Merced, but they have with everything else)

Intel was sure steamed about that ruling and has taken steps to ensure that no one can gain access to IA-64 in the same way. IA-64 has dozens of features that are patented or in the process of being patented. It is not good enough to be able to build a CPU that is 99% compatible with IA-64. Look at Lexra; they designed a MIPS clone embedded core but couldn't include the unaligned load and store instructions because SGI/MIPS had patents on the concept and implementation. In the end Lexra couldn't claim MIPS compatibility. This doesn't seem to have hurt Lexra but the embedded control world is a completely different market than desktop computers, servers, and workstations.
Aside from that, IA-64 is huge creaking edifice designed by a two company committee. In terms of ease of implementation Alpha is a much simpler and streamlined design. And with equivalent semi technology the EV68 Alpha wipes up the floor with the merced IA-64 and is much compact too (roughly half the die size). Alpha can likely be licensed by AMD and design assistance, both official and unofficial, would flow in AMD's direction. Also, many of AMD's key designers are ex-Alpha designers. Contrast that with IA-64 where much of the ISA will be hidden in secret "Appendix H's" and the public information will not always correspond to Intel hardware. Intel tied up AMD in court on and off for a decade over x86. They will be happy do the same for IA-64 and will have the benefit of the legal lessons learned in the first war.

Joe Consumer walks into Wal-Mart to buy a computer, is all set to go for the cheaper model, when he finds out it doesn't have Intel inside. "Hey! I don't want any of this A-M-whatever stuff, I want good, quality Intel Inside!"
Finally, with Intel having a near monopoly on the processor market, they can lean hard on third-parties to try and restrict competition. They're more subtle about it then Microsoft, but we have seen it plenty of times.

Maybe they're doing that, but it's hardly a trivial task from the software standpoint; I've no idea which OS suppliers (the free UNIX-flavored OSes, perhaps, but what about Microsoft, Sun, SCO, etc.?), compiler suppliers (GCC, perhaps), and other software suppliers (e.g., Oracle) will be willing to back them.

Intel have quacked and barked in the past; they may be more likely to quack than bark, but that doesn't prove beyond the shadow of a doubt that they will.
I don't think Intel has any plans to make it easy for anybody other than themselves or HP to build IA-64 implementations; I have no reason to believe that this necessarily means that they'll keep stuff secret forever - I suspect they'll make heavy use of patents, instead.

Really? I thought all you needed for a new viable platform was a compiler!

Last I checked, it *was* trivial getting protected-mode 16-bit 286 programs, even operating systems, to run on 32-bit 486es, even without emulators or access to the source code or compilers. Why? Because the 486 supports the 286's instruction set.
If, as the Register states in the article I linked to, the K8 is going to be a re-engineered K7, why in the world would they break its support for the IA-32 instruction set? So, like the 486 in 1992, the K8 would be the fastest x86 available and support all the old x86 programs. Now, it would additionally have support for an extended 64-bit mode. Like the 486, the additonal bits aren't the primary selling feature -- the selling point is speed and backwards compatibility.
And Linux, already with a single codebase supporting several 64-bit processors in addition to IA-32, would be a natural candidate for a K8-64 port, and it's a major OS for the kind of inexpensive servers the K8 would likely be found in initially. This at least gives the K8-64 a potential future...

I have no reason to believe they would. (If you thought I did, you read more into what I said than I put there....)
(Or the 386....)
The additional bits in the 386 weren't the primary selling feature for 16-bit OSes. If there's never a 64-bit OS for x86-64, they might as well just do a really fast implementation of boring old 32-bit x86.
So the only thing that'd make a 64-bit version of the x86 instruction set worthwhile would be, err, umm, an OS that supports the 64-bit mode, and compilers to generate 64-bit code - and, for at least some applications, probably other 64-bit software, e.g. 64-bit database software.
Maybe a 64-bit Linux port, say, would give its 64-bit mode a use; however, I'm not sure "inexpensive servers" would need a processor with a 64-bit virtual address space (they might want a processor and OS that supports more than 32 bits of physical address, but you can get such an x86 processor from Intel and, presumably, AMD now; I'm not sure what OSes support it - allegedly, W2K will, and I assume Sequent's Dynix/PTX supports it, albeit probably only on Sequent's big NUMA machines.

I have a novel idea: It's an electronic component, right? Let's give it an electronic-style part number. Since it's compatible with the 8086 processor, let's call it something like the 80986 or the 81086 shall we?
