Intel Xeon w7-2555X

The Intel Xeon w7-2555X is a 14-core (28-thread) processor built for the workstation CPU market. It launched in Q3 2024 with a suggested retail price of $1,069. It is part of Intel's Xeon W lineup, which is based on the Sapphire Rapids microarchitecture. The w7-2555X is compatible with Intel Socket 4677 motherboards and is fabricated on Intel's 10 nm manufacturing process.

Memory and Cache

The Xeon w7-2555X supports DDR5 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Xeon w7-2555X has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 33.75 MB.

Cores and Clock Speeds

The Xeon w7-2555X features 14 total cores which can process 28 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.3 GHz, and it can boost up to 4.8 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Xeon w7-2555X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
