The Intel Xeon E5-2603 v4 was a server/workstation processor with 6 cores, launched in Q1 2016. It is part of the Xeon E5 v4 lineup, using the Broadwell-EP architecture with Socket LGA2011-3. The processor operates at a base frequency of 1.7 GHz and does not support Intel Turbo Boost technology. Xeon E5-2603 v4 features 15 MB of shared L3 cache, providing efficient data access for multi-threaded workloads. Intel manufactured this processor on a 14 nm production process, offering improved power efficiency compared to previous generations.

With a TDP of 85 W, the Xeon E5-2603 v4 is relatively power-efficient for a server-class processor, though proper cooling is still recommended. The processor supports DDR4 memory with a quad-channel interface, offering support for DDR4-1866 modules. ECC memory is supported as well, which is crucial for mission-critical applications to prevent data corruption. For system expansion, the Xeon E5-2603 v4 provides PCI-Express 3.0 connectivity.

This processor lacks integrated graphics, so a dedicated graphics card is required for display output. Hardware virtualization (Intel VT-x) is supported, enhancing virtual machine performance. The processor also includes advanced security features like Intel AES-NI for accelerated encryption. While it doesn't support Hyper-Threading (resulting in 6 threads total), its six physical cores make it suitable for basic server workloads and virtualization scenarios. The locked multiplier limits overclocking potential, as expected with most Xeon processors.
