Intel SR204 E5-2643 v3 Server Processor

The Intel Xeon E5-2643 v3 is a workstation and server processor from Intel's Haswell-EP generation, built on the LGA 2011-3 platform. With six cores running at a 3.40GHz base clock and support for Hyper-Threading, it delivers 12 threads of processing power tuned for applications that demand both high clock speeds and multi-threaded throughput. The 20MB SmartCache provides generous on-die memory for reducing data access latency, which is particularly beneficial in rendering, simulation, financial modeling, and other compute-heavy professional workloads.

This processor connects via the QPI bus at 9.6 GT/s and supports quad-channel DDR4 memory through compatible X99 or C612 chipset platforms. It can also be deployed in dual-socket configurations for workloads that scale across multiple CPUs. At 135W TDP, it requires a capable cooling solution, but in return it offers one of the higher clock speeds available in the E5-2600 v3 family—making it a deliberate choice for users who prioritize per-core performance over sheer core count. For existing LGA 2011-3 builds or budget-conscious workstation upgrades, the E5-2643 v3 remains a strong performer in its class.
