Check this out. Take note of the memory interface work that is being done at IBM. While they are talking about CPU system memory (called cache memory), it's worth following the development. siliconinvestor.com Greg

From Feb. 99 PC WORLD The Future of the PC Swift Silicon Brookwood's concerns haven't slowed Intel's rapid-fire introduction of new processors, nor will it keep the chip giant from making big changes to the PC platform. Later this year we'll see a new type of system memory called Direct Rambus DRAM (RDRAM) start to replace synchronous DRAM (SDRAM). Direct RDRAM memory uses a thin and fast connection to more than double the amount of data available to a PC's processor. MPEG-2 video, Accelerated Graphics Port-enhanced 3D graphics, and high-end imaging applications will all benefit from the faster RAM. Alas, the performance boost will come at a cost. Brookwood expects both RDRAM chips and compatible motherboards to cost more than today's SDRAM technology, at least through 2000. As a result, he says, universal adoption of Direct RDRAM won't happen until 2001. Nonetheless, the technology has the support of key CPU players like Advanced Micro Devices and Compaq's Alpha division, making it a lock to succeed SDRAM. Around the time that RDRAM gets its start, Intel will roll out a new version of AGP, the graphics-only bus that lets graphics cards call on system RAM to create highly realistic 3D images. AGP 4X will double the data rate of today's AGP 2X cards. The extra speed may help eliminate some delays that occur when AGP-enhanced games juggle detailed 3D scenes. Keep in mind that your mileage may vary. Even though you'll need an AGP 4X graphics card to take full advantage of the new bus, most older AGP 2X cards should work just fine in the new slots, according to Niles Burbank, product manager for ATI Technologies, a graphics hardware maker based in Thornhill, Ontario. By late this year, many lower-end machines will not have a separate graphics chip at all, as more tasks begin to fall directly to the chips attached to the processor. Intel's Celeron-based motherboards will begin using the company's forthcoming 810 chip set, which will include a built-in graphics controller. Likewise, Cyrix's MXi processor, which is expected to arrive this spring, will integrate a 3D graphics controller.
