Description:AMD Athlon processor family is a line of high-
performance processors based on AMD K7
architecture. Earlier Athlon processors with
backside L2 cache were produced in a Card Module
package. With the introduction of a Thunderbird
core, which added on-die 256 KB L2 cache, it
became possible to package the processors into
smaller and cheaper PGA package. Because the L2
cache on Thunderbird Athlon CPUs is running at
the same speed as the processors, T-Bird Athlons
are faster than slot A Athlons with their slower
L2 cache. Athlon microprocessors received another
performance boost when their bus frequency was
increased from 200 to 266 MHz. The fastest
processors from the AMD Athlon CPU family are 1.4
GHz A1400AMS3C with 266 MHz front side bus (FSB)
and 1.4 GHz A1400AMS3B with 200 MHz FSB.

This is the infamous 1GHz, the race was brutal
between Intel and AMD to see who could hit 1GHz
first. Both companies turned out products that
were basically overclocked and unstable to get
there. All in all Intel lost the race and the
speed crown for some time.
