And for L1 cache
, other mitigation methods might be used.
For example, the L1 cache
has a size of around 16 to 64 K and offers the highest level of performance.
Figure 12 is a comparative view of cache bus power for a 32 KB L1 cache
with 64-/32-/16-bit bus size.
The new benchmark results were achieved in an environment running SAP R/3 Enterprise Release 4.70 solution on a combined solution including NEC's Express5800/1320Xe, 32-way SMP, Intel Itanium 2, 1.6 GHz, 32 KB L1 cache
, 256 KB L3 cache, 9 MB L3 cache, 128 GB main memory, and iStorageS2000 SAN disk array system, Windows Server 2003 Datacenter Edition for Itanium-based systems and SQL Server 2000 (64-bit).
Each Power5 core has 64KB of L1 cache
, and the two cores on a chip share a 1.9MB, L2 cache.
900, 16-way SMP, SPARC64 V, 1.35 GHz, 256 KB L1 cache
The cache model simulated a direct mapped cache similar to the L1 cache
of our Sun machine.
It includes a 16-KB instruction and 16-KB data L1 cache
(32 KB total) and an external 512-KB half processor speed Level 2 cache.
The Athlon also features a 128KB on-chip L1 cache
and a 512KB standard L2 cache, scalable to 8MB.
Note, however, that Transmeta's processor has 128KB of L1 cache
, while Intel's chip has just 32KB.
