Intel Core 7 253PE vs Intel Core Ultra 5 235A Comparison

The Verdict

The benchmark data delivers a clear outcome: the Intel Core Ultra 5 235A wins 16 of 17 head-to-head tests, while the Intel Core 7 253PE manages a single victory. The Core Ultra 5 235A is the faster processor in nearly every workload category, with an average benchmark score of 48201 compared to 40557 for the Core 7 253PE. That places the Core Ultra 5 235A in the 90th percentile of all CPUs, while the Core 7 253PE sits in the 87th percentile.

The data indicates the Core Ultra 5 235A should be the default choice for users prioritizing raw performance across rendering, encryption, compression, and single-threaded tasks. The Core 7 253PE, however, holds a decisive lead in integer math, which may matter for specific computational workloads. The Core 7 253PE also offers ECC memory support, a feature absent from the Core Ultra 5 235A, making it the more appropriate option for systems requiring error-correcting memory.

Architecture Differences

The two processors come from different Intel design families. The Core 7 253PE uses the Bartlett Lake codename and is built on a 10 nm process node at Intel's own foundry. The Core Ultra 5 235A uses the Arrow Lake-S architecture, its codename Arrow Lake, and is manufactured on a 3 nm node at TSMC. This process difference is substantial: the Core Ultra 5 235A packs 17,800 million transistors into a 243 mm² die, while the Core 7 253PE has no transistor count or die size listed in the database.

Core and thread configurations diverge sharply. The Core 7 253PE has 10 cores and 20 threads, indicating simultaneous multithreading. The Core Ultra 5 235A has 14 cores but only 14 threads, meaning it does not use hyper-threading. Despite having fewer threads, the Core Ultra 5 235A wins multi-threaded benchmarks, which points to higher per-core efficiency from the newer architecture.

Cache hierarchies also differ. The Core 7 253PE has 80 KB of L1 cache per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Core Ultra 5 235A has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 5 235A provides more per-core cache, while the Core 7 253PE has more total L3.

Clock speeds and memory support separate the pair. The Core 7 253PE boosts to 5.50 GHz with a base clock of 2.50 GHz. The Core Ultra 5 235A boosts to 5.00 GHz with a base clock of 3.40 GHz. Both support dual-channel memory, but the Core 7 253PE accepts DDR4 and DDR5, while the Core Ultra 5 235A only supports DDR5. Memory bandwidth favors the Core Ultra 5 235A at 102.4 GB/s versus 89.6 GB/s for the Core 7 253PE. The Core 7 253PE supports ECC memory, which the Core Ultra 5 235A does not.

PCIe lanes differ as well. The Core 7 253PE provides Gen 5 with 16 lanes from the CPU. The Core Ultra 5 235A provides Gen 5 with 20 lanes. Sockets are incompatible: the Core 7 253PE uses Intel Socket 1700, while the Core Ultra 5 235A uses Intel Socket 1851. Integrated graphics also differ, with the Core 7 253PE featuring UHD Graphics 730 and the Core Ultra 5 235A featuring Arc Xe-LPG Graphics 24EU.
