Not Etched But Print Mark on the CPU Die
Test Benched Pen Marks on the case.The AMD Athlon Mobile Duron 1000 MHz ES (Engineering Sample) with the part number DHD1000AMT1B and the AHMBA stepping code is a highly collectible vintage processor based on the "Morgan" core architecture (Socket A / Socket 462).There is no record of such a ES DHD1000AMT1B with AHMBA Stepping code in any online CPU DatabasesAHMBA Stepping Code was used in production of800 MHz (DHM0800ALS1B) and 950 MHz (DHM0950AQS1B) only but this ES Version is also is built based on the same Stepping Code.

Here is the technical breakdown of the specifications embedded within that specific part number and stepping:Core Specifications

• Brand/Line: AMD Duron (Morgan Core, Family 6, Model 7)

• Frequency: 1000 MHz (1.0 GHz)

• Bus Speed: 200 MHz FSB (Double Data Rate, 100 MHz actual clock)

• Clock Multiplier: 10x

• Cache: 128 KB L1 Cache + 64 KB L2 Cache

• Socket: Socket A (Socket 462)

Part Number Breakdown (DHD1000AMT1B)According to official AMD K7 architectural naming conventions listed on databases like CPU-World

• DH: Duron Desktop/Mobile Processor

• D: Mobile configuration (often low voltage or power-optimized)

• 1000: 1000 MHz operating frequency

• A: Ceramic Gauze PGA Package (Socket A)

• M: Operating voltage (nominally 1.75V, though mobile variants vary)

• T: Maximum die temperature case limit (usually 90°C)

• 1: 64 KB L2 Cache size

• B: 200 MHz Front Side Bus

The AHMBA Stepping CodeThe AHMBA text printed on the core die denotes its manufacturing batch and physical architecture properties:

• Morgan Core Identity: The "H" in AHMBA represents the second-generation Duron core (Morgan), which added Intel SSE instruction support to AMD's traditional 3DNow! extensions.

• Engineering Sample Status (ES): Standard retail Morgan chips often carried steppings like AHLCA or AHLFA. An AHMPA designation, particularly when matched with an open multiplier or labeled explicitly as an "ES", makes it an early pre-production test chip sent to motherboard manufacturers and engineers before the public launch.
