CF-29 1.4Ghz v 1.6Ghz

Hi there

Is there any advantage in upgrading from a 1.4Ghz to a 1.6Ghz Toughbook?

 

Why yes its a 0.2 advantage.

All jokes aside the MK4 and MK5 (1.6GHz) models do have some more features. Some have an integrated card media reader, I believe they can take more RAM as well.
This is a good place to go for model comparison information:

DDR2 is on the mk4 & 5 as well

 

Well some 1.4GHZ are Mk3 and some are Mk4.

The Mk4&5 have a later chipset and use DDR2 RAM. The max that a Mk4or 5 has run RAM wise, is 2.25GB and that is only on the 256MB on board models. The rare models with 1GB onboard RAM will do 2GB.

No one has proven what the max RAM a Mk-1-3 will run yet, but I suspect 2GB with the right board, meaning 1GB or 256MB on board. I am not sure that that both of the configurations exist. The Mk-1-3 uses DDR1 RAM.

The Mk5 has a SDHC RAM slot. The Mk4&5 have two external USB ports.

That is about it, I think.

 

My MK3 has two external USB ports.

 

My MK3 has 2 but my MK1 has one. I do like the SD reader in my MK5

 

Send it back to Panasonic at once, it is defective!

OR, I could be wrong about the MK1-3. It appears some older models have two USB ports. Perhaps someone else knows the correct break down? It has appeared to me that the Mk3 was somewhat of a transitional model.

 

To my knowledge, all the CF-29HTM50BM retired SBC Mk3's have two USB ports: one next to the power adapter port on the right side and one on the rear under the fold-down door.

My Mk2 has a PS/2 port where the rear USB port resides on the Mk3.

 

The Pentium-M chips all clock down to the same speed when they're running on battery. It's a trick that Intel introduced to increase battery run times.

Unless you tweak the power settings, you'll see no performance difference when you're on the road.

 

The same with my MK1

 

BBB, I don't understand this... clock down to what speed?

When you said 'power settings', do you mean 'Power Option Properties' > Minimal Power Management??

All of the Pentium-M processors (including the 738 & 778 used in the CF-29) clock down to 600MHz when they're running in low-power mode.

If more agressive power settings are enabled, they will boost their clock-speed via Speedstep. However the Speedstep intervals are identical - you can only hit full clock speed if you're running on wall-power, or if you disable Speedstep (which comes at the expense of battery life).

That will disable Speedstep in Windows. But it disables other power saving features also, so you'll see your battery run-time cut in half.

There are other software tools that give you fine-grained control over Speedstep.
