Additionally, let's not forget that rambus is also dieing because of intel's laughable chipsets, which need some fundamental rewireing to support such a different memory philosophy.
Don't get me wrong - Rambus is a bad buying idea, and the company is highly associal - but the idea is a good, and eventually necessary one. The memory of the future might not be RDRAM, but it certainly won't be any form of SDRAM.
e.g. 600MHz DDR SDRAM has half a wavelength of 25 centimeters - So that's how far apart signals will be. Signals certainly don't normally arrive at the same time in a clock cycle (this depends on where the memory is getting it from, whether a bank switch occurs, etc.) that's already a very, very, small margin in _theory_. And in practice it's going to be very hard - I'ld think. The fastest DDR SDRAM around is about half as fast, at the moment.

All wires have capacitance, inductance and resistance. To change the voltage on a wire (change the charge), current must be applied to it. When the current is applied, it takes time for the voltage to change. The amount of time it takes is determined by how much capacitance has to be charged and how much current is avaliable to charge it. It also takes time for voltage to get from one end of the wire to the other. The time for travel is figured by the capacitance of the wire, the length of the wire and the inductance of the wire. To reduce the time, (inverse of speed) the
(1)transistors must be improved for more current
(2)The wires must have lower resistance
(3) the amount of capaticance of the wires must be reduced. (using low K dielectrics)and
(4) wires must be shorter by using smaller transistors
These are all items that research and developement do constantly. IBM is using copper instead of aluminum. Intel is working on the same. Low K dielectrics are being used. Lithography is pressed to use smaller features so the parts are closer and more of them fit. Also the clocking on the chip has to be uniform. If you want to see some of this stuff in action, Look up the wavelength of 4 Ghz. 1 wavelength away on a wire isn't very far. A wire with a signal caries a signal slower than the speed of light. A clock signal on this wire would be one full clock cycle late at the other end of a wire one wavelength long. At 4 Ghz, how far away can your cache memory be before a memory read request and clock get to it and the data return without being late? 4 Ghz signals tend to treat wire as an antenna (it is a radio frequency). Signal tends to leave one wire and show up on another causing errors called crosstalk. All of these issues are the things that have to be worked out to produce a faster chip. Oh by the way-add heat and power distribution to this dense mix of transistors. That is another couple of issues.

AMD dropping Mustang now is Great (Score:1)
At this point in development, AMD knows that the processing power of the Athlon core is heavily dependant on the latency of the L1 cache. Much more so than the PIII. The instruction pipeline cannot feed information into the core fast enough.
My understanding is that the Mustang/Palamino group was supposed to increase the accuracy of the branch prediction AND increase the number of instructions available to the core by enlarging the cache.
The downside of a large L1 cache is that a larger L1 cache has a larger latency (to demultiplex the addresses) than a smaller cache.
After running several tests in simulation and possible early silicon, AMD probably realized that a very large L1 cache does not add value to the processor, especially when coupled with DDR RAM. Instead, the money and research should probably go toward the other, more promising research.
The extra cache is bound to increase the price quite a bit when you consider the increased probability of lower yields.
Think about it cost-wise, would you prefer a 1.2 GHz with 1 MB cache, or two 1.0 GHz with 256 KB for the same price?
There are OTHER x86 companies out there that stick with technology for too long regardless of the performance, and wait to change only after the market has incurred the cost of their mistakes.
Score one for AMD.

I don't know if I can wait for x86-64 but it sounds so good. Anyone know what quarter they want it to ship in? Maybe I could hold out 'till Q2 2001 but beyond that it gets rather painful.
Some trouble with such large amounts of cache on-die are: larger dies, higher power requirements, and much more heat. Larger dies cut manufacturers' yeilds two ways:
1. Less cores/wafer
2. Higher failure rate.
Prices would likely be sky high for a processor with 2 MB of L2 cache on-die. I doubt many people/companies would pay the premiums with x86-64 around the corner.

On the other side, AMD has very fast processors, and a multi-processor capable chipset(using DDR memory) is on its way.
So, as far as I can see, AMD decided to a) not risk everything on a chip that would be difficult to design/manufacture, and b) rely on their current, fast, processors and the soon to be released multi-processor, DDR capable chipset.
Add to the mix that we might be seeing chipsets with ~8 megs of integrated cache within the next year or so, and you see why they might not want to "waste" time on a "server"-oriented processor.

While clock synch is an issue, this isn't what constrains the speed of traditional memory interfaces.
sdrams modules (both traditional and ddr) use a simple node driver on it's output and don't do any tailoring of the waveform or impedance matching. This is fine as long as you keep most of your signal energy at longer wavelenghts than the length of the wire (or more precicely pcb trace) so that you can fully charge the entire trace to the voltage you want. Speedwise this technique got pretty hard limits on ow fast we can go, which cannot be resolved by just improving processing or circuit technique.
However as we increase the datarate pr. pin it become infeasable to shorten the trace enough to do the transmission this way.
Enter the transmission line. On this kind of interface we can have multiple bit 'on' the wire at the same time. This does however tight control of the wire's analogue properties and the waveform issued by the driver. When we do this we must limit the number and severity of bends and corners on the wires, and both sender and reciever must be designed to spesific impedances.
Since an TL interface is expensive both on die and pcb resources rambus opted to serialize the architecture to reduce costs and and increase capasity.
Eventually we will have to go to TL interfaces, not only to ram but just about all interfaces on our computers. However, right now it's apparent that TL tech isn't quite there yet. When they can push the speed up to say 2GHz we might want to reevaluate, though hopefully without rambus' disruptive influences.

Traditionally, you could get a cheap Intel 2-way SMP board like the BX or (bleh) 820, which was great for the server and 'workstation' OEMs like Compaq and IBM, as well as better mb shops like Asus. But no longer - now one has to get a 840/Rambus model. And worse, the Pentium 4 will be introduced with no SMP support, which implies that they will be forcing all SMP users to buy (emasculated) Xeons (for big $$$).
The net effect is that Intel is jacking the prices on SMP systems. (Consipriacy theory - perhaps this is to make the Itanium look more affordable.) So, AMD has a huge market opportunity here to take the 'low-end' SMP market away from Intel with the 760MP and standard cheap Athlons. Now, they just need to win some OEM bids for "departmental servers" and "workstations", and if they are technically successful, they'll be in much tighter with the big OEMs (who don't totally trust them yet.)
Plus, there's a bunch of production logistics with producing a high-margin, low-volume Xeon-like chip. Furthermore, you pretty much have to have a top-tier server OEM to move those systems, which AMD doesn't have right now.

I agree that x86 is a bad thing, but it is certainly not a killer.
Furthermore, I think its important to face the fact that software developement cost is probably the biggest expense around, and it is simply better to have a compatible chip for old software than it is to get a new thing - even if the new thing is a bit faster - because speed is just one factor in the whole equation.
