What's the fastest

1: SDRAM
2: DDR
3: RDRAM

Fastest how ? Bandwith and Mhz ability

 

[CyberFed]

RDRAM performs better than DDR and its better for overclocking IMHO so go with Rambus

That's right...in YOUR OWN OPINION....

Mostly WRONG though....jeesh.

calm down Therapture
you can nicely explains why he is wrong

DDR is better in OCing than RDram, and once you reach DDR333, your DDR's bandwidth is higher than Rambus. there are alot of benchmarks on DDRams in the Memory Forum, and almost all of them have Rambus PC800 as references. you can clearly see that DDR is beating Rambus with DDR333 or over.

***In theory***

SDRAM is the slowest. PC66 can do 66MHz, PC100 can do 100Mhz and PC133 can do 133Mhz. Boards that support SDRAM are available for all CPUs.

DDR RAM is sort of mid way between SDRAM and RDRAM. It comes in four flavours:
PC1600.....100MHz*2 = 200MHz
PC2100.....133MHz*2 = 266MHz
PC2400.....150MHz*2 = 300MHz
PC2700.....166Mhz*2 = 333MHz

DDR400 is set to come out soon, using the DDRII spec. It will run at 400MHz max (200*2). These speeds are the max rated speeds - they will not always run at these speeds by default.

RDRAM is Rambus DRAM and is available as PC600 and PC800 (I think). The RAM runs at 600MHz and 800MHz respectively.

RDRAM is only available for intel CPUs and makes better use of th P4s 400MHz FSB than DDR RAM.

Is this list updatable yet ?

What - like this:

PC3000 -> 200*2 = 400MHz

ok right forgot

Here's my take on the issue:

SDRAM is the slowest, period. You should really try to get DDR/RDRAM if at all possible. It's not that much more expensive.

DDR RAM was lacking behind RDRAM for quite awhile, but with PC2700, it's caught up, and with PC3000, it's surpassed it by quite a bit.

There are a few significant advantages with going with DDR RAM. DDR RAM is significantly cheaper than RDRAM. Secondly, it's useable in both AMD-based and Intel-based (depending on the chipset) motherboards, while RDRAM is only available for Intel chipsets. Thirdly, Intel is discontinuing support for RDRAM and pursuing the cheaper DDR RAM. Finally, DDR RAM is far superior for overclocking, especially since many Intel-based boards don't exactly make it easy to overclock.

Rdram does run at 800 mhz but it only has a 16 bit data bus(can only process this much info at a time) as a apposed to a normal 32 bit data bus in the other ram. Correct if I'm off.
