Core i9-12900E

The Core i9-12900E is a 16-core / 24-thread processor based on the Alder Lake-S (2022) architecture, manufactured on a 10 nm process node. It reaches a maximum boost clock of 5 GHz from a base frequency of 2.3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 30 MB (total) of L3 cache, plus 1.25 MB (per core) of L2 cache and 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 28,170, placing it in the High-End performance tier as a Aging generation product. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 13,420.

The Core i9-12900E fits into the LGA1700 socket and supports PCIe 5.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR4, DDR5 Dual-channel memory at speeds up to DDR5-4800 (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. Integrated graphics: UHD Graphics 770 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

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

The Core i9-12900E 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. Recommended cooling: Air Cooler 120mm+.

At an average price of $500, the Core i9-12900E delivers 56 PassMark points per dollar. Performance ranking position: #478 out of all indexed processors.
