| I have some experience with the various versions of K6-2+ and III+.
| Here's my two bits worth...
|
| The performance differences between the two vary widely depending on
| what software you use. (I doubt his mom will be playing much UT .
| 3DGames are very FPU dependent, so extra L2 cache doesn't play as
big
| a role.

Extra L2 cache plays a role in nearly all aspects of operation.
CPUmark99 results for the 2 chips were slightly different, tho not a
remarkable difference (maybe 59vs 55, been so long I don't remember
the actual scores). The fact that running UT with the 2 different
cpus resulted in only a small difference indicates performance of the
2 is quite comparable, as such games are actually quite memory
intensive. The bottleneck in a 3d (direct3d or opengl) game is
typically the graphics card, as fps rarely scales with CPU speed when
the graphics card is the limiting factor.

|
| It also depends on the system chipset and amount of RAM installed.
For
| example, on the FIC motherboard you mention, the MVP4 chipset only
| caches 128MB of RAM. Adding more RAM means the remainder will not be
| cached by the motherboard, only by the on-chip L2 cache. In this
| situation, the larger cache of the K6-III+ makes a world of
difference
| and a K6-III+/450 will be much faster than a K6-2+/550 for most
tasks.

Agreed, with the exception of the caching capability of the mvp3 and
mvp4 chipsets, both chipsets cache 256meg (actually 255 meg due to a
design decision regarding use of the onboard TAG ram) in write-thru
caching mode. If the intended usage is for word
processing/email/web-browsing then the performance differences between
similarly clocked k62+ and k63+ CPUs will not be noticable to the
average user unless more than 256 meg of ram is installed.

|
| I'm not sure what chipset is used in the laptop, but the ALI
chipsets
| are a bit better in this regards. Also, unless you know how to
change
| the settings for the laptop, just swapping chips would cause the
| K6-III+ to run at 550Mhz and 2.0v. I doubt very much that it would
| work reliably.
|
| All in all, I don't think a K6-2+/550 to K6-III+/400 swap would be
| wise, unless you're looking to reduce heat or increase battery life.
| Then it might make sense.
