LE == "Light Edition" actually.
VE == "Value Edition"
The VE is more or less the 7200 with the TCL unit removed and a
few other minor changes, at a lower clock speed, but with the
addition of dualhead (it was the first dualhead Radeon).
The original Radeon LE was made for Asian market and produced by
a 3rd party company, however these boards made their way back to
the North American market as well. The Radeon LE is 100%
identical to a Radeon 7200 in every way chipwise (regardless of
any marketing materials or other claims one finds online). The
only difference between the Radeon LE and the Radeon 7200 is that
it has 166Mhz memory in it just like the OEM Radeon 7200, but it
is intentionally underclocked to 148Mhz or 143Mhz (I don't
remember exactly), and the BIOS on the card disables the TCL unit
at BIOS POST time, so that the drivers think it has no TCL
support. The card autodetects as a Radeon 7200 however as it
uses the same PCI ID (because it is the same chip). Further
details can probably be found in a web search, however anything
you read that discounts anything I've said is 100% incorrect.
;o)
The other LE cards such as 7500LE, 8500LE, etc. are the same as
their non-LE counterpart except at a lower clock speed of about
10-15% or so. I don't remember if they have any other changes or
not, but I think only the clock speed and perhaps memory speed
or type of memory was different on them. That's web searchable
also.
Some ATI trivia that'll hopefully be useful. ;o)
