Xeon E-2378

The Xeon E-2378 is a 8-core / 16-thread processor based on the Rocket Lake-E (2021) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.8 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 16 MB (total) of L3 cache, plus 512K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 17,069, placing it in the Mid-Range performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,821, while multi-core reaches 9,986.

The Xeon E-2378 fits into the LGA1200 socket and supports PCIe 4.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR4-3200 memory at speeds up to DDR4-3200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 128 GB across 2 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers.

It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: Yes — enables running virtual machines efficiently (important for development and server workloads).

The Xeon E-2378 has a rated TDP (Thermal Design Power) of 65 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately.

At an average price of $562 (MSRP: $362), the Xeon E-2378 delivers 30 PassMark points per dollar. Performance ranking position: #924 out of all indexed processors.
