# Ddrram Vs. Rdram?

## #1 — marianil, 2002-07-31T11:51Z

Alternativ 1:
\#Intel Pentium 4 processor 1800 MHz med 256Kb Cache, 400MHz FSB
\#Intel® 845 - E chipset 400MHz/533MHz FSB USB 2.0
\#256MB DDRRAM (1x256MB)
\= 16,963 kr 

Alternativ 2:
\#Intel Pentium 4 processor 1800 MHz med 256Kb Cache, 400MHz FSB
\#Intel 850-E chipset/533MHz FSB
\#256MB 400MHz RDRAM 
\=18,213 kr 
 
Om det är samma konfig. i övrigt!

Det som skiljer sig är vilket chip det är och minnestypen.

Vilket alternativ ska jag sats på?

Jag har kört på paketet med DDR-minne, för RDRAM är så överskattat.

Varför anser du att RDram är överskattat? \*nyfiken\*

För dom är snabba i teorin, men inte så snabba i praktiken. Därför det känns lite dumt att betala ett överpris för en produkt som inte håller vad den lovar.

> However, very preliminary signs indicate that the current little benefit/substantial additional cost will shift to some benefit/somewhat less additional cost. It is too soon to determine whether the additional benefit would be worth the additional cost for most, since we don't know the values of either, nor will know before the fall at earliest.

> 
> If RDRAM production ramps up to at least the degree needed to initially supply Willamette, and prices are at least somewhat competitive with DDR, RDRAM stands a good chance of becoming the general desktop standard. If these conditions are not met, this is very unlikely to happen.
