AMD Goes Intel Route?

Source: X-bit LabsAdvanced Micro Devices Incorporated goes Intel route these days when it obliges end-users to acquire expensive registered PC3200 DDR SDRAM memory modules for AMD Athlon FX-51 microprocessors. The company, however, does not pin any illusions on registered memory modules, as next year it plans to launch another version of its chips with integrated memory controller supporting ordinary DDR SDRAM memory modules even in dual-channel mode.
In Fall 1999 Intel Corporation, Santa Clara, California, unveiled its Pentium III “Coppermine” processors with i820 (Camino) chipsets with RDRAM memory controller. It was clear, PC600, PC800 RDRAM memory was not necessary for Intel Pentium III CPUs and very few users utilized Intel’s RDRAM supporting P6 platform. One year later, in November 2000, the Santa Clara, California-based chip-maker launched its Pentium 4 processor and i850 chipset with only RDRAM support. RIMMs have always been the most expensive memory modules and even enthusiasts did not want to adopt them. Furthermore, RDRAM and supporting platforms were not able to show tangible performance increase over the less expensive AMD Athlon as well as Intel Pentium III with PC100 or PC133 SDRAM. What is happening now? AMD tries to go the same route by forcing to use expensive PC3200 registered DIMMs with its desktop AMD Athlon FX-51 processors.

There had to be a high-end consumer chip. To deliver such a chip, they had to work with what they had. That's the Opteron. They added 3200 support to the memory controller and fired it off. If they don't want to pay for that memory, they can get 754 or wait for 939.
The biggest difference between AMD and Intel, and x-bit admitted this indirectly in their own article, was the fact that AMD already announced to update their architecture for unregistered DDR support by the middle of next year at the absolute latest. Intel didn't drop RDRAM for almost two years.

am I going to have to buy new memory? or will my PC2100 and PC2700 DDR modules work?
The rdram days are over.
must have, will sell an internal organ to have. I should be able to get the cash to build several machines if I sell a kidney.

Here is the story...

Even on a Via chipset, at 220 fsb 1:1, the memory score in sandra is way over 6000/6000 with ECC memory(!). It takes around 245-250 1:1 or 290 5:4 for an Intel setup with DDR ram to do that numbers. We are talking bandwidth effective stuff here. Goddayum i want that stuff to play with. The 939 chip with dual ,non ecc, unbuffered DDRII....10,000/10,000 in sandra perhaps?
Now featuring DDR 667..
333 x 2 x 16 = 10667*91% = 9706MB/s of bandwidth on Dual Channel DDR667. Tack on another 150MB/s for it not being registered, it's around 9806. Tack on another 200MB/s from some mild overclocking, there's the 10GB barrier.
I edited it a little
This stuff looks good. I have seen what is supposed to be the first test of a prescott and i can say it sucked monkey-arse.
Unless Intel have something else up in their sleeve, buying amd stocks NOW might be a winnar in 1 year.
tack on another 120MBps to correct for an increase in efficiency due to a slightly more optimized memory controller.
tack on another 100MBps for by running CAS 1.5 2-2-2.
take on . . . oh forget it.
