DEC Alpha chip
Item #717
This Lucite paperweight from Digital features their very first Alpha chip, the DECchip 21064, introduced in 1992.

The DECchip 21064, codenamed "EV4", was a 64-bit superscalar RISC microprocessor. It used 32 bit instructions with a built-in integer, floating point, and load/store unit, an 8 KB data cache and 8 KB instruction cache.

The DEC 21064 chip measured 1.39 x 1.68 cm. It was manufactured by DEC using CMOS technology with 0.75 micron photo lithography, had three metal layers, and contained 1.68 million transistors.

At it's introduction in 1992, the DEC Alpha 21064 was the fastest microprocessor available, running at an impressive 150 MHz.
