It's not that simple. Systems using the TSE are very different than the ones using the LAN91C111 so it's not safe to assume that you will get the same performance with the DP83848. You need to try it.

If you get a bandwidth that is sensibly lower than the PHY's theoretical limit (as in your example, 48Mbps on a 100Mbps phy), then you will probably get the exact same speed with a gigabit PHY. This kind of figure indicates that your speed is limited by the CPU side and not the PHY itself.
