NOTES:
1. The register size and external data bus size are given in bits.
2. First level cache is denoted using the abbreviation L1, 2nd level cache is denoted as L2. The size
of L1 includes the first-level data cache and the instruction cache where applicable, but does not
include the trace cache.
3. Intel processor numbers are not a measure of performance. Processor numbers differentiate fea-
tures within each processor family, not across different processor families.
