Intel Pentium MMX - 1997         Pentium MMX can be looked as the enhanced version of the original Pentium. Besides newly implemented MMX (Multi-Media eXtension) instructions and 64-bit data declaration, Intel also increased its internal cache size from 8KB to 16KB and lowered the working voltage to 2.8V. From now on, all the Intel processors for desktop computers supports MMX instructions. All of the Intel official documentation indicates that only 166Mhz-233Mhz Pentium MMX were released, but, did anyone notice that there actually are Pentium MMX 133Mhz, 150Mhz and 266Mhz CPUs in my collection? How could this be? In fact, the 266Mhz should be the mobile version of Pentium MMX (code name: Tillamook). I don't know about that 133Mhz and 150Mhz, though. The TT300 at lower right is actually TT80503300 Mobile version, which is also the fastest Pentium avalible in the market and pretty rare, too. Despite its market value, the TT300 is, in my opinion, one of the most beautiful chips in my whole Intel collection.
