All my machines, except for one 486 laptop, have been AMD based. However, my 800MHz Athlon died, and I need to upgrade *now* without waiting for the Hammer, which disappoints me greatly. So, the best PC I can build from existing parts is going to be a dual Xeon box. I'd rather have a single Hammer because its 64-bitness and strong, efficient performance at lower clockspeeds appeal to me--but I'm buying a Placer motherboard and dual Xeons because they're here *now*. They also offer a guaranteed upgrade path to probably 3.5GHz or better since Intel is good about keeping Xeon platforms viable for some time. Whereas, if I were to buy a non-Hammer Athlon right now, I'd be almost guaranteed to have little upgrade room by comparison.

      AMD just lost a long-time customer because of their lateness to market with Hammer, and I'm sure I'm not the only one.

      That is absolutely not true. Having 64 bits allows you to access a larger amount of total memory, and it lets you put more information in each instruction. The amount of data you can work on in any given clock cycle is proportional to the cache access and bandwidth and the register size (Neither of which inherently need 64 bit long instructions).

      Think about it - the main problem in terms of pushing computing power these days is electron migration, caused by extremely high clock rates.

      Say it with me: There is no such thing as electron migration. There is, however, something called electromigration and it has nothing to do with clock rate. The problem is that as electrons flow in a conductor, they collide with lattice ions and push these ions around a little bit. This isn't a problem in the macroscopic world since wires are so big, but in a microscopic (or nanoscopic) scale this can lead to melting and diffusion of the conductor into the surrounding medium. The copper atoms slowly diffuse into the silicon around them, almost like a gas (a very slow moving gas).

      Since these motions are caused entirely by the force of electrons colliding with the atoms, they are completely determined by the kinetic energy of the electrons -- i.e., how fast they move. And that in turn depends on the mean-free-path length (a property of the conductor) and the electric field within the conductor. It has absolutely nothing to do with clock rates.

      Newer, high-speed chips may suffer more from electromigration than slower chips, but this is only because the new chips have much thinner wires and are therefore subjected to a greater current density at a given voltage. I.e., more electrons flow per unit area, so the number of electron-atom collisions goes up.

It's about tradeoffs... the more you try to "do" in a clock cycle, the more circuitry you have to have actually "doing" something.

This, of course, makes chips more and more complex (read: harder to test, design, etc.).

      Back in the day, there were two schools of design philosophy. The "Brainiacs" believed in doing more per clock. The "Speed Freaks" believed in designs optimized for increased (and increasing) clock speed.

      One of the things I think the Brainiacs realized is that the more you try to do in a single clock, the bigger and more complex the cpu becomes, and it is a greater than linear increase in complexity. Complexity causes the clock speed to be hard to increase (longer pathways may result from the increased complexity = lower clock speeds). The Speed Freaks aren't without their problems either -- I/O (keeping the cpu fed), heat, clock signals, etc.

      Design approaches like Intel's EPIC are a hybrid of the two approaches, to some degree. It is supposed to make the chip design more simple, eliminating a lot of the forwarding/ordering logic in the CPU, by offloading these responsibilities to the compliers (which have to become more complex). At the same time, it provides a 'wide' set of execution units. This idea is to make the CPU simpler, which helps increase clock speed, while not sacrificing compute power (because you have a bunch of execution units). The challenge of the compilers is to keep all the execution pathways in the EPIC cpu full. Of course, with this design philosophy, you are at the mercy of the quality of compiler writers. EPIC tries to tradeoff complexity/speed in this way. Of course, Intel is having its share of problems getting EPIC to fly (chicken and egg problem with software to some degree, cost, etc).

      Which is right? It's a matter of preference I guess. Both designs enable fast parts. I guess the only real question in my mind is which design more future value (to the company that is making the cpus) -- how much of today's design can be reused when going forward? how hard is it to come out with version++ from where you are today? how hard is it to get more performance than what we have today?

If the price is reasonable, we'd buy them right now even if they ran at half the speed of a top-of-the-line Pentium4. The ability to address greater than 4 Gbytes of memory directly just outweighs even fairly significant differences in raw CPU performance. In different words, even a slow pointer dereference is still a lot faster than read/seek/write.

    The K5/K6 were Pentium/Pentium II clones, but the K7 was basically AMD's coming out in the Microprocessor realm, and has been extremely successful!

    Nope.

    Around 1995, AMD was really struggling to build a Pentium class processor. In 1994, the first company to ever reverse engineer an intel processor and create a functional equivalent was NexGen and their Nx586. This processor utilized a RISC core and a translation unit to get 386 instructions into RISC form. I actually owned two of these, a Nx586 66 and a Nx586 100. They were pretty funky. FPU's were optional, but most of the Nx586 100's had FPUs on board. There was always talk of putting a FPU socket a la 487 on the boards, but it never happened.

    Neadless to say, AMD purchased NexGen in late 1995 and released the K5, a clone of the Nx586. The K6 was the first processor released by AMD which was faster than the current Intel processor, a oft forgotten fact. For about 3 months before the Pentium II was released, the K6 233 was 5% or so faster than the Pentium Pro 233.

    The K6 and Athlon lines of AMD all utilized the same internal RISC core with a translation unit.

    So, you are wrong, no one ever cloned the Pentium or Pentium II. A lot of nasty history between Intel and AMD in the 386 days made sure that would never happen ever again. I wish I could find some fun links on the Nx586 for you, but even on google it seems to have been forgotten.

This is also not a well-thought post and wreaks of legacy apeal, of which AMD's Opteron benefits from. Itanium has never failed. The Linux kernel and all the supporting software to feature a stable and near-fully-featured operating system has been completed nearly 6 months ago! Itanium-based computers were available from HP, IBM, and Dell. Intel is releasing an Itanium2. Binary compatibility for X86 is non-existant in the Itanium and Itanium2 because it is a completly New Architecture. Support for Microsoft Windows and old DOS programs does not constitute binary compatibility of an architecture; that is the operating systems job to define. Yes, lack of Microsoft(R) Windows(TM) on IA64 will not alure retail Microsoft-brand customers to Intel...Linux will lure customers to Intel that need a somewhat Unix-compliant environment that once again (Alpha platform) features 64bit precision. What is the difference between a standards-compliant C program compiled in Linux/x86 versus Linux/IA64? The end-product's binary interaction with the architecture is what is different; protocol compliancy is retained. GPL software is just a quick compile away for IA64 by independant programmers and users. The real issue is in the non-opensource or non-interested programmers to port their software to the new protocol-compliant OS/platform. Looking at it another way, you didn't define a monopoly by Microsoft(R). As long as GNU and Linux are around, there is no monopoly from Microsoft(R) to speak of. Yes, Microsoft *tries to force companies out of business by doing certain things, but every company retains their freedom(TM) to contract with others...Linux is the monopoly of IA-64 in this respect, or whoever the fuck someone says should be accountable for another company's product; which IMHO is why I think political opinions/statments and the commercial(contract) world is evil and everyone is better off to be recognized by the goodness of their work, mind, and soul.

    IA64 and Opteron both have their markets; Linux bridges them together with *protocol* compatibility: which Microsoft chooses to *not* dream about. Microsoft is rumored(announcment without supporting evidence) to be porting Microsoft(R) Windows(TM) to IA64; just nothing yet.

    Look at a different picture where Microsoft has lost its monopoly but Linux is not a big force. Then the leading OS vendors have to follow whatever is the dominant chip. Ofcourse in this case there can be a monopoly in the chip market like the intel monopoly. The OS vendors will build only for intel, and we will have less improvements. But if we have a non monopoly situation we will have OS vendors supporting more than one chips, and there will be choice.

    Next take a look at what happens when Linux and other Free Operating Systems constitute a monopoly, ie proprietory OSs have been relegated to niches. In this case all kinds of chips are supported. A hardware vendor is not at the mercy of the OS vendor, but can produce his own distribution and provide it along with the hardware. This is possibly the best of all worlds in my opinion.

    Well you can look around you and see that current situation is precisely because there is a MS monopoly. AMD provides a processor but only because it is a clone of intel. No independent processor design can exist, in this monopolised environment. If Linux was the monopoly OS, Alpha wouldn't have died.
