Intel Itanium Cache Sizes

Intel has now published specific information on the cache sizes of the 64-bit server CPU, Itanium, on an FTP site . Accordingly, the size of the level 1 cache will only be 32KByte (16KByte instructions + 16KByte data) and would be the same size as with the Pentium II/III (AMD Athlon 64KByte + 64KByte). The L2 turns out to be 96 KByte even significantly smaller than the 256KByte of the Intel Pentium III (Coppermine). To compensate for these very small cache sizes for a 64-bit CPU, Intel relies on a 2 or 4MByte L3 cache for the Itanium, which also gave the old K6-3 good performance. However, the price will be correspondingly high. However, significantly larger L1 and L2 caches are expected for the successor McKinley, which is due to appear at the end of 2001.
