Poll: DDR Really worth it? (Updated)

[GoldenTiger]

Worth it... $90 for Crucial 256mb PC1600... why not?

DDR PC1600 and Rambus PC-800 has the same theoretical max bandwidth at 1.6GByte/s DDR PC2100 will have ~2.1GByte/s bandwidth. Although DDR has slower interface (at 200/266 Mhz), The bus is wider. 64bit instead of 16bit of Rambus. plus at this point Rambus has a high latency issues, which DDR don't really have it (well, it did, but it's almost as fast as regular SDR SDRAM).

IMHO DDR PC2100 has a better future. and right now all the software compiler maker hasn't start to tweak their compiler to take advantage of the system yet (well, samething for 3DNow!, SSE, SSE2....), and the chipsets are still in the first generation. Hopefully in a year everything will be mature and the over performance will reaching almost to what the theory predicts. and hopefully by that time CPU speed will not outgrow the memory speed by too much.


Anyone remember back in the P-90 days a company called Oceantech is producing a special MB that uses Enhanced DRAM for 486? the EDRAM chips has some build in cache, which in a lot of benchmarks, the 486DX4-100 actually beatup the P-90.. but of course, it didn't last,
since 486 is already at the end of it's life.

For anyone wondering how I got multipliers working on the A7M266:

Go here.

Just bought a Infineon 256MB PC133 yesterday. I think I'd stick with SDR chipsets for a little longer. Now SDR chipsets are very mature and SDR SDRAM is dirt cheap. DDR offers insufficient speed advantage which can be easily offset by overclocking the FSB of BX, i815 and KT133A.

BTW- The AMD 760 runs the memory in sync with the bus, so it's not 200/266 with PC2100, it's 266/266.
