200 series = Up to 2-way servers and workstations
800 series = Up to 8-way servers and workstations
yy—Indicates relative performance within the series. In other words, an AMD Opteron processor
model 244 is higher performing than an AMD Opteron processor model 242, etc.
Table 3 further explains the differences between AMD Opteron processor series and model
numbers.
