Architecture Differences

The two processors represent distinct design philosophies from Intel. The Core 7 253PTE uses the Bartlett Lake codename and is built on Intel's 10 nm process node, fabricated in-house. It contains 10 cores with 20 threads, indicating hyper-threading support. The Core Ultra 5 245HX belongs to the Core Ultra Series 2, uses the Arrow Lake-HX codename with Arrow Lake architecture, and is manufactured on a 3 nm node by TSMC. This newer part features 14 cores but only 14 threads, meaning it does not use hyper-threading.

The cache hierarchies differ substantially. The Core 7 253PTE allocates 80 KB of L1 cache per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Core Ultra 5 245HX provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 5 245HX has larger per-core caches but less total L3. The Core Ultra 5 245HX also reveals its transistor count at 17,800 million and die size at 243 mm², while the Core 7 253PTE does not list these figures.

Memory support creates another divergence. The Core 7 253PTE supports both DDR4 and DDR5 memory with dual-channel operation, achieving 89.6 GB/s bandwidth. The Core Ultra 5 245HX supports only DDR5, also dual-channel, but reaches 102.4 GB/s. The Core 7 253PTE supports ECC memory, which the Core Ultra 5 245HX does not. PCIe connectivity also differs: the Core 7 253PTE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 5 245HX offers Gen 5 with 20 lanes.

Integrated graphics distinguish the pair. The Core 7 253PTE uses UHD Graphics 730, while the Core Ultra 5 245HX uses Arc Xe-LPG Graphics 48EU. The Core 7 253PTE targets the desktop market segment on Intel Socket 1700, while the Core Ultra 5 245HX is a mobile part on Intel BGA 2114. The Core Ultra 5 245HX has an unlocked multiplier, whereas the Core 7 253PTE does not. The Core Ultra 5 245HX released earlier on 2025-01-12, with the Core 7 253PTE following on 2026-03-08. The Core 7 253PTE carries a launch MSRP of $384.
