Hi,

My old Pentium system finally packed in and I plan to do a cheap, short-term upgrade of the motherboard to keep things rolling before I get a brand-new, more powerful system in about 6 months time.

I am thinking of the MSI KM3M-V motherboard fitted with a slow-ish Sempron processor (performance isn't important at the moment). My questions are:

1) Would a Sempron 2200 require a cooling fan? (I'm trying to keep costs and complexity down to a minimum)

2) What FSB speed is suitable for a 2200 processor (the fastest possible?), or is it only the RAM speed that determines that?

3) What speed rating of DDR Ram is recommended (PC2100, PC2700, etc) for a Sempron 2200 based system? (I know the faster the RAM, the faster the throughput, but it's not linear and I don't want spend extra money in going from, say, a PC2100 DDR RAM to a PC3100, if it's just to get a 1% effective increase).

4) Just out of curiosity, what theorectical speed improvement is to be expected in going from a Pentium III 500MHz, 100MHz bus to a Sempron 2200, say 333MHz bus, system (all other things being equal).


Looking forward, does AMD have a comparison chart (either theoretical or "real system") of their own processor range and against Intel's?

Many thanks.

yes it would.

The XP2200+ runs at 13.5x133MHz (1800MHz)
The Sempron 2200+ runs at 9x166MHz (1500MHz)

But...a faster bus speed can improve performance...

Semprons run with a 166MHz front side bus, so your ram has to be able to run at that same speed for synchronous operation, you'll need PC2700 aka DDR333 memory.

Pricewise, the faster ram is actually cheaper, ram is backward compatible speedwise. Sort of like your car, you can do 100KM/h on the highway but your car can still drive 30KM/h in a school zone.

You should see a significant improvement in speed, the Sempron 2200+ is marketed against the newer Intel Celeron-D processor running at 2200MHz.

Due to the construction of AMD cpu's they can do more instructions per clock with a slower overall speed.

There are many 3rd party comaprisons available on the internet. Although most are based against gaming applications.

Many thanks MD. Really appreciate it.
