Since I can’t seem to reply to the original thread from 2017, I’m making a new one.

(Tells me “the license you chose for this post is not valid”) - whatever that means.

Anyways;

Something people forget about the 400 (200MHz) bus speeds. Literally EVERYTHING in the system communicates over the Front Side Bus. So overall system performance increases as a whole. Not just memory speed and CPU processing ability.

Easy way to test this is run a benchmark off memory and hard drives (preferably an SSD) off the SATA controller off an nForce2 equipped board and see the results between the 266 & 400 bus speeds. Easy enough to do with any 400 processor as they can all be downclocked

Sorry to revive an old thread. It when I went from my Palomino 1800+ which I already punched to 166MHz FSB (was a pain with this chip to get it there) to the Barton 3200+ at 200(400)bus, beyond the CPU clock speed, my system was significantly faster.

Going from a 266 bus to a 400 mhz bus is going to be a big improvement. Doubling the on chip cache and a newer chipset probably helped too.

No. The south bridge speed, which is handling most of I/O, will remain unchanged.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

No doubt.

Chipset --> Interconnect --> Bandwidth
VIA KT333 --> V-Link --> 266 MB/s
nVIDIA nForce --> HyperTransport --> 800 MB/s
SiS 735/745 --> MuTIOL --> 1.2 GB/s
