Yes, larger chips means more transistor, inferior manufacturing or both. And it is also the number of extra chips they need. The Intel card contains the chip, the PHY and a little eeprom. > I'm running a few of these in higher-end (V480-range) Sun machines > running Solaris.

But I'm reasonably certain that an Intel card (later updates of Solaris 10 support those for SPARC as well) would perform better. A friend of mine used an i82541 based card in a SB1000 running Solaris 10 and it worked and performed very well. Kind regards -- Matthias Scheler http://zhadum.org.uk/
