JiminyDigits writes "AMD recently
revealed a few more details of their upcoming quad-core platform
architecture called 4X4. With CPU bundles affectionately dubbed 'Quad
Father,' AMD is taking advantage of the inherent benefits of their
HyperTransport interconnect technology to directly connect a pair of dual Athlon
64 desktop chips together with system memory. Details here show
a dual socket motherboard that support a whopping 12 SATA connections, four
X16 PCI Express slots (x16,x8,x16,x8 configuration) and few other bells and
whistles. Supposedly Quad Father kits will come with matched CPUs from
2.6GHz up to 3GHz."

It's 4x4 so next step is 8x8 and ultimately to 64x64.

There are something like 3 parts to PCIe-speak on motherboards:
What they're saying here is that you're getting 2 x16 and 2 x8 lanes slots, but all the slots have a physical x16 size, which means that you can plug pretty much anything in it, including 4 PCIe graphic cards at once (since graphic cards require physical x16).
I'm not sure I've been perfectly clear though, anyway it's fairly clear when you talk about slot size versus number of lanes.

Which means it will cost $1000-$2000 just for CPUs and motherboard. AMD's and Intel's quad cores will cost a grand also, which limits all of this to people with more money than sense.
If they're going to allow dual processors, why not let people use the $150 2.0GHz dual cores? Then the whole thing will come in under $500 and have much wider appeal.

Also, $1000 doesn't seem that expensive, spending about $2500 on a computer (which you probably wouldn't need to upgrade for about 5 years) wouldn't be that crazy, would it? It seems cheaper than spending $1000 every year and a half (which might be an average upgrade cycle)

The target price is under $1000 for the CPUs and (presumably) board. That really doesn't price it out the range of people who were previously buying Athlon FX and Intel EE CPUs. Keep in mind that this is a high-end enthusiast-class platform, rather than the future of AMD's mainstream computing. If you just want dual CPU dual cores, you can buy an Opteron 200-series workstation for less probably. You won't get 4 PCI-E x16 slots and 12 SATA ports, but who needs that anyways? Or, you could just wait until 3Q of 07 and get a native quad core CPU.
Would it be great if they made it cheaper so that everyone could have one? Absolutely. But then they would be cannibalizing the sales of their other higher-end CPUs (why buy a $700 FX-series when you can spend $300 on low end X2 CPUs and get more performance?).

4x4 uses low-latency unbuffered RAM while servers use ECC RAM. More importantly, you can already buy dual CPU Opteron motherboards and chips. They've been capturing LOTS of market share from the Xeon, especially at the quad chip (8 core) level where the Xeon's obsolete FSB architecture falls down. Some vendors even have 8 CPU (16 core) boxes. And then there's Cray's Opteron-based supercomputers...
4x4 is basically an Opteron 2xx-series platform adapted for the desktop enthusiast market.

Absolutely. AMD full-time all-core processing provides outstanding traction with almost any air- or water cooled system. It constantly monitors processing conditions, sensing any loss of traction and automatically transfers processes from the cores that slip to the cores that grip. And cores that grip are especially nice if you're into Doom3 or any other game that demands a lot from a processor. Like grid computing, where AMD is a consistent
Re: (Score:3, Interesting)
Actually, that's not a bad analogy. Each AMD CPU has its own memory controller and bank of memory so there's lots of memory bandwidth to go around, whereas an Intel dual CPU config has both processors accessing memory through an obsolete FSB architecture. Accordingly, an Intel dual CPU machine will be spinning its wheels in situations where an AMD 4x4 has memory bandwidth to spare.

It was explained awhile back, but 4x4 isn't directly related to the core count. Otherwise, why wouldn't a dual CPU workstation class system with dual core CPUs be considered 4x4?
4x4 actually is in reference to 4 CPU cores and 4 video cards, at least that is the way that it was explained to me.

I'll bet you a beer that in 10 or 15 years you'll look back on the above statement and admit that you were completely wrong. You may be right that current apps, and even current types of apps, will receive limited benefit from dozens of processors, but what you're missing is that massive parallelism will enable new types of application that are barely imagined now.
Perhaps you remember the famous (apocyphal?) quote, "640K of RAM ought to be enough for anybody". I suspect that the author of that statement thought that because all apps at the time ran in 80x40 monochrome text mode, and what text-mode app could possibly need so much RAM? He didn't forsee the migration to GUI-based apps that was made practical by the availability of large amounts of RAM.

Basically, if you farm out four tasks to a 2xDual intel setup, the memory bandwidth available doesn't scale. IE, you can add more dies, but at the cost of reducing the memory bandwidth available to each of those dies (to/from system).
With AMD's setup, adding a new die also adds a new memory controller (they're on the die, remember?), which in turn increases the amount of memory bandwidth available (to/from system).
