Great update. Looks really good for AMD!

Ali, thanx alot for that Byte article on the Alpha/K7 EV6 bus. 3.3 x the memory bandwidth of Slot 1 or Slot 2. Impressive. After reading this, I think CPQ saw the same thing that I see -- a future for the Alpha chip because of future motherboard compatibility. Petz

Ali, thanks for the post on the AlphaBus, it's the first description I've seen. It's nice to see you are useful for something Based on the article I must say that the AlphaBus just goes to show you what can be done when cost and real estate are of no concern. It's a very nice design but don't expect to see it in a desktop system anytime soon. Just too expensive to manufacture. The pincount is way to high. When the author compared it to an Intel archeticture, he made some real fundemental errors, seemed strange for someone who seemed knowledgeable. An example is <In a Socket 7 system, the CPU, L2 cache, main memory, and PCI bus all hang off the same local I/O bus. P6 systems are similar, > Not true at all. A bus interface unit stands between the processor bus and memory, PCI and AGP in all x86 designs. He goes on to say, <In an EV-6 system, the CPU talks directly to the chip set over a private channel. The chip set, in turn, branches off to all the other buses: main memory, PCI, and AGP. Each of those buses runs at its own speed. Main memory could run at 66 or 100 MHz while the PCI bus runs at 33 MHz and AGP runs at 66 MHz.> Except for the private bus to the chipset, this is the same as every x86 chipset out there, depending on if it also has AGP. Intel's AGP runs at 133mhz, faster than the Alpha chipset. All busses are independent and run at their own frequency, so what is he talking about? The memory doesn't yet run at 100mhz, but it will long before you will ever see an Alpha chipset with an AMD processor on it. Even you Ali with your limited knowledge and even more limited intelligence wouldn't have made this mistake. EP
