AMD Mobile Athlon 4 processor

One unusual thing about this engineering sample is that the part number is printed on the processor with ink, unlike the production processor, where the part number is engraved. Also, like older Athlon socket A processors, this microprocessor doesn't have special rubber pads that support the heatsink and ensure that the CPU die is not damaged during heatsink installation. All other Mobile Athlon 4 processor have these pads.
