"This is by no means intended to be a full-blown review of the KA7-100. Our
focus will instead be on the T-Bird/KX-133 combination as a viable upgrade
option. There are still many questions and some recent discouraging news
about changing the multiplier on the Socket A T-Bird, and the problems many
have had with overclocking Athlons via the front side bus are no secret.
Couple that with expense and work involved with preexisting Athlon users
upgrading their CPU's and their motherboard to take advantage of the
Thunderbird's "performance-enhancing on-chip L2 cache memory," one begins to
wonder if this combination is worth temporarily putting off the inevitable
transition to the Socket A form factor."
