Front view of Intel Xeon 7041

Reasons to consider the
Intel Xeon 7041

Report a correction
Supports more CPUs in SMP configuration 32 vs 1 31 supports more CPUs in SMP configuration
Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3 GHz vs 1.6 GHz More than 85% higher clock speed
Much more l2 cache per core 2 MB/core vs 0.5 MB/core 4x more l2 cache per core
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Higher Maximum operating temperature 76 °C vs 61.4 °C Around 25% higher Maximum operating temperature
More threads 4 vs 2 Twice as many threads
