The Athlon XP-M 1400+ (OPN AXMS1400GXS3B) was a 32-bit x86 microprocessor developed by AMD and introduced in March 2003 for thin and light mobile and value PCs, a low voltage Athlon XP-M processor in a smaller µPGA package as opposed to mainstream and desktop replacement models. It was based on the K7 microarchitecture, had a 256 KiB on die L2 cache, and operated at 1.2 GHz (12 × FSB frequency; the number in the model name and OPN is a relative performance rating). Its 100 MHz, 64-bit front side bus supported raw data rates up to 1.6 GB/s. The processor was manufactured on a 130 nm copper process at AMD's Fab 30 in Dresden, Germany. One of the lowest frequency members of the series, the low voltage Athlon XP-M 1400+ was already delisted by August 2003 and replaced by the Athlon XP-M 1500+ at a price (tray, 1k) of $ 57.

[Edit/Modify Cache Info]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
