Could someone please tell me the approximate values at which RDRAM performs similar to DDR. Do any of them have any distinct advantages?

ddr is cheaper

DDR RAM is much cheaper than RDRAM.

The max speed of DDR is 400Mhz and RDRAM is 800Mhz (i think maybe faster)...

DDR and RDRAM can be used with Intel based computers.

RDARAM cannot be used with AMD powered machines. (dont quote me on that)

DDR RAM is fast enough for the home user.

You only need the RDRAM is your doing some powerful computing.

actually i think that theoretically both ddr ram and rd ram run at nearly the same speed .. previously it was rd ram that was twice as fast as sd ram and since ddr is twice as fast as sd ram it works out to about the same as rd ram..

some one once posted a link with a lot of technical mumbo jumbo and the exact data transfer rates etc which proved the above.. i'll have to dig and see if i can find it..

oops dual post.. would you kindly delete one for me FE ? ;)

I think thats Dual - DRR

Different to DDR.

RD is faster but you cannot compare as they entirely different DDR is lots cheaper

i didn't quite get you there powerless...drr ?

ddr is double data rate..

never heard of drr..

have a look at the chart here click here and look at the bandwidth coloumn since thats the one that gives you an idea about the speed
