Architecture Differences

The two processors come from fundamentally different Intel lineages. The Xeon w3-2525 uses Sapphire Rapids, built on a 10 nm process at Intel's foundry, and is classified as a Server/Workstation part. The Core Ultra 5 235H uses Arrow Lake, built on a 3 nm process at TSMC, and is classified as a Mobile part. The node difference is significant: the Core Ultra 5 235H uses a more advanced manufacturing process, which helps explain its higher boost clock and better single-thread performance.

Core counts differ sharply. The Xeon has 8 cores and 16 threads, while the Core Ultra 5 235H has 14 cores and 14 threads. The Xeon relies on Hyper-Threading to reach 16 threads from 8 cores, while the Core Ultra 5 235H has more physical cores but no additional threads per core. In multi-threaded Cinebench tests, the Core Ultra 5 235H still wins, indicating that its extra cores outweigh the Xeon's thread advantage in those workloads.

Cache hierarchy also differs. The Xeon w3-2525 has 80 KB of L1 per core, 2 MB of L2 per core, and 22.5 MB of L3 cache. The Core Ultra 5 235H has 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. The Xeon has more total L3, but the Core Ultra 5 235H has larger per-core L1 and L2 allocations.

Memory support is a major differentiator. The Xeon supports DDR5 with a quad-channel memory bus and 140.8 GB/s of bandwidth, plus ECC memory. The Core Ultra 5 235H supports DDR5 and LPDDR5X with a dual-channel bus and 102.4 GB/s of bandwidth, without ECC. The Xeon's memory bandwidth is 37.5 percent higher, which likely contributes to its data compression and integer math wins.

PCIe connectivity also separates them. The Xeon provides Gen 5 with 64 lanes (CPU only), while the Core Ultra 5 235H provides Gen 5 with 8 lanes (CPU only). The Xeon is designed for expansion-heavy workstation or server boards, while the Core Ultra 5 235H is a mobile part with limited PCIe allocation. The Core Ultra 5 235H includes integrated Arc Graphics 140T, while the Xeon has no integrated graphics.
