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. Performance of Athlon microprocessors was improved even further when
the frequency of the Front Side Bus 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.
Athlon line of processors was replaced with AMD Athlon XP processor family.

Engineering sample
For each speed grade there were two versions of Athlon Thunderbird A processors with different core voltages. The processors with 'M' in the part number (like A0850AMT3B) had 1.75 core voltage. The processor with 'P' part numbers - like this A0850APT3B CPU - had core voltage 1.7 Volt. Due to lower core voltage, this processor war running slightly cooler that A0850AMT3B.

Staggered organic PGA (Socket A/Socket 462)
This AMD Athlon 1000 microprocessor is quite different from other Thunderbird CPUs. This processor it packaged into organic Pin Grid Array package - that package became common in the next generation of Athlon XP microprocessors. Judging by the 26876 package number we can assume that this is one of the earliest versions of organic PGA packages. For comparison - the earliest Athlon XP packages are marked as 27100.

All AMD Athlon processors, except the earlier ones, have 4 rubber pads located in package corners. The purpose of these pads is to prevent die substrate damage during installation of the fan/heatsink. Without the pads the die substrate could be easily cracked or chipped when a heatsink, which is not properly aligned to (not parallel to) die surface, is pushed down. The pads do not allow significant tilting of the heatsink, but even they cannot protect the die when excessive force is applied to the heatsink. Die substrate of this CPU shows typical damage which was caused by incorrect heatsink installation.

The fastest Athlon processor with Thunderbird core. This is the best upgrade choice if your motherboard supports only Thunderbird core, and has support for 266 MHz FSB. As this CPU has 266 Mhz front-size bus, it is on average 10% faster that Athlon 1400 with 200 MHz FSB. As of now (May 2006) they are still much easier to find than Athlon 1400 with 200 MHz FSB.
