How much faster is ddr333 verses pc133 sdram?

[jtw]

I am going to upgrade my motherboard from an Intel d845wnl (using 256mb pc133 sdram) to a Asus P4S8X (using 256mb ddr333). I will reuse the cpu, a 1.5ghz Pentium4. How much faster will my computer be? Will it be very noticable? Or will it only be marginally faster? Also, what is the max thoughput of sdram? I know the max of ddr333 is 2.7gigs/sec, but what about the sdram?Thanks for your time in advance!

the theoretical output of your pc133 sdram is about 1.1 g./s

IF I were You I would get a faster Cpu (northwood) along with your upgrade. You should notice a pretty big difference then.

But you must remember its all relative. If you are going from a p2 400mhz to a p4 2ghz you it will be that much more noticable.

For high end processors, P4 and XP2000+ and above, DDR makes a big difference.

IMHO

when I do go DDR 333 I shall do a comparison with my existing kt133a MB but that wont be for a few weeks

I would get any Intel PE chipset board if buying now. Sis 648 did not sit too well with me. Asus P4PE-L is a super board. Only thing missing is AGP 8X.

about 200 faster

I agree

DDR333 runs at 166MHz, so it is 33 MHz faster than PC133.

However DDR can send double the information per cycle.

SDRAM PC 133 = 1.1 GB
DDR 266 = 2.1 GB
DDR 333 = 2.7 GB
Dual DDR 266 = 4.2 GB
theoretical output
so DDR is about 1 GB faster then Sdram (2.1 - 1.1 = 1)
On a newer chip you will be able to tell the speed diff
I hope thats helps
