The Verdict

The data indicates two distinct usage profiles. The Intel Core Ultra 5 250K Plus is the stronger overall processor, with a 19.5% higher average benchmark score (66855 versus 55919) and a higher percentile ranking (93 versus 91). It wins the majority of workloads, particularly those involving encryption, compression, floating-point math, and multi-threaded rendering. The 18 cores, though without hyper-threading, provide substantial parallel throughput. The 3 nm process node and TSMC foundry production contribute to its efficiency profile, and the higher memory bandwidth of 115.2 GB/s supports data-intensive tasks.

The Intel Core 7 253PQE, while trailing in aggregate performance, delivers specific strengths. Its single-core Cinebench R23 result is exceptional, 96% ahead of the Ultra 5 250K Plus, and it holds a 36% edge in Cinebench R15 single-core. The 20 threads from its 10 cores, combined with a 5.70 GHz boost clock, give it strong legacy single-threaded performance. Integer math also favors the Core 7 253PQE by 10.2%. The 33 MB shared L3 cache is larger than the 30 MB on the Ultra 5 250K Plus, which may explain some of the integer workload advantage.

Users who prioritize multi-core throughput, encryption, compression, and modern floating-point workloads should select the Intel Core Ultra 5 250K Plus based on the recorded data. Users who need maximum single-threaded performance in legacy Cinebench versions, or who work with integer-heavy code, will find the Intel Core 7 253PQE more suitable. The Core 7 253PQE also supports DDR4 memory, which may be relevant for platforms that retain older memory modules. The Ultra 5 250K Plus supports DDR5 only, with a higher memory bandwidth of 115.2 GB/s versus 89.6 GB/s.

Architecture Differences

The recorded data shows distinct architectural approaches. The Intel Core 7 253PQE, codenamed Bartlett Lake, belongs to the Core 7 generation. It uses a 10 nm process node fabricated by Intel. The 10-core, 20-thread configuration relies on hyper-threading to achieve thread parallelism. The L1 cache is 80 KB per core, L2 is 2 MB per core, and L3 is 33 MB shared. This larger L3 cache, combined with a 5.70 GHz boost clock, explains the strong single-threaded Cinebench results. The Core 7 253PQE supports both DDR4 and DDR5 memory, providing platform flexibility. PCIe Gen 5 with 16 lanes covers CPU-attached devices. The integrated UHD Graphics 770 provides display output capabilities.

The Intel Core Ultra 5 250K Plus, codenamed Arrow Lake Refresh, belongs to the Core Ultra Series 2 and the Ultra 5 generation. It uses a 3 nm process node fabricated by TSMC, with 17,800 million transistors on a 243 mm² die. The 18-core, 18-thread configuration has no hyper-threading; each core is a physical thread. L1 cache is 192 KB per core, L2 is 3 MB per core, and L3 is 30 MB shared. The larger per-core caches and the 3 nm process contribute to the higher single-threaded PassMark score of 4757. The Ultra 5 250K Plus supports DDR5 only, with 115.2 GB/s memory bandwidth. PCIe Gen 5 with 20 lanes offers more CPU-attached expansion.
