About This Product
The Intel Xeon E5-2643 v3 is a 6-core, 12-thread server/workstation CPU from the Haswell-EP generation. With a high base clock of 3.4 GHz and boost up to 3.7 GHz, it offers strong single-threaded performance for its class. While its multi-threaded performance is modest compared to higher core count Xeons, it can be suitable for applications that benefit from higher clock speeds rather than raw core count in server or workstation environments. At its current price, it competes with newer, more efficient consumer CPUs offering similar or better multi-core performance.
Verdict
βBest for budget workstations needing high single-thread performance on the LGA 2011-3 platform.β
Performance Benchmarks
Scores are grouped by benchmark family so it is easy to compare raw speed, threaded output, and real-world value without mixing scales.
