Description:	The first Itaniums ran at 733 and 800MHz. Itanium is Intel's first true 64-bit chip, and uses their EPIC (Explicitly Parallel Instruction Computing) instruction set (IA-64 computing). The EPIC instruction set is heavily compiler dependant. The Itanium is capable of 6 gigaflops. It has 4 integer units, and 2 floating point units. Itanium comes with 2MB or 4MB of L3 cache. Also, it feature L1 (32K - 16K instruction, 16K data - 4-way set associative, 32-byte lines) and L2 (96KB dual-ported 6-way unified, 64-byte lines) cache on chip, with L3 cache in the Itanium package (which is smaller than 3x5" index card), but not on the chip. OEM's can also add a 4th level of cache, or L4 cache. The Itanium is capable of dealing with up to 16 GB of main memory. It shipped initially with the 460GX chipset, and used standard PC100 SDRAM at 100MHz. The Itanium contains a 10-stage instruction pipeline. As for registers, the Itanium has 128 floating point, 128 integer , 64 predict, and finally 8 branch registers In practice the performance of the Itanium was lackluster, mainly because it was highly compiler dependent. If the code was not perfectly compiled for it it would be very slow. However, if the code was clean, it would fly. But code is like pigs, rarely clean, so the Itanium is fast, when pigs fly. ------------------------------- L3 Cache: 2048k Bus: 133MHz --------------------------- This is the Commercially released final version.
