Intel Core 7 253PE vs Intel Core Ultra 5 250K Plus Comparison

The Intel Core 7 253PE and Intel Core Ultra 5 250K Plus represent two distinct approaches to desktop processing. The data shows a clear performance hierarchy between them, but the nature of that gap varies significantly depending on the workload. The Core 7 253PE holds a narrow lead in some single-threaded legacy tests, while the Core Ultra 5 250K Plus dominates almost everything else, particularly in multi-threaded and data-intensive tasks.

Head-to-Head Benchmarks

The most striking result in the recorded data is the single-core performance in Cinebench R23. The Core 7 253PE scores 3512, which is 55.3% ahead of the Core Ultra 5 250K Plus’s 2261. This is the largest win for the Core 7 in any test. It also wins Cinebench R15 single-core, scoring 354 against the Ultra 5’s 328, a 7.9% difference. These results indicate that for applications relying heavily on a single thread and specifically optimized for that older benchmark, the Core 7 has a distinct advantage.

However, this advantage does not carry over to other single-threaded tests. In the PassMark single-thread test, the Core Ultra 5 250K Plus wins with a score of 4757, which is 16.9% higher than the Core 7’s 3955. Similarly, in Cinebench R20 single-core, the Ultra 5 scores 2603, beating the Core 7’s 1475 by 43.3%. The data shows that the Core 7’s single-thread lead is specific to certain benchmark suites, not a universal trait.

In multi-threaded workloads, the Core Ultra 5 250K Plus is decisively ahead. In Cinebench R15 multicore, it scores 4640 versus 2507, a 46% lead. The gap narrows somewhat in Cinebench R23 multicore, where the Ultra 5 scores 30867 against the Core 7’s 24880, a 19.4% advantage. In Cinebench R20 multicore, the Ultra 5’s 18442 is 43.3% higher than the Core 7’s 10449.

The PassMark suite shows similar dominance. The Ultra 5 wins data compression with 568721 against 339133, a 40.4% lead. Data encryption shows an even larger gap, with the Ultra 5 scoring 42144, which is 56.4% higher than the Core 7’s 18385. The extended instructions test sees the Ultra 5 at 44565, a 51.1% advantage over 21806. Floating-point math shows a 50.3% lead for the Ultra 5 (162692 vs 80870), and random string sorting shows a 52.6% lead (69090 vs 32777).

The largest delta in the entire benchmark set is in the PassMark find prime numbers test. The Core Ultra 5 250K Plus scores 486, which is 71.6% higher than the Core 7’s 138. The integer math test shows the smallest multi-core gap, with the Ultra 5 scoring 125091, only 8.7% above the Core 7’s 114158. The PassMark multithread test has the Ultra 5 at 51596, a 43.3% lead over 29271, and the physics test shows a 47.2% lead (3494 vs 1845). Overall, the head-to-head results show the Core Ultra 5 250K Plus wins 15 of the 17 recorded tests, with the Core 7 253PE taking only 2.

The Verdict

The benchmark data is unambiguous for users who prioritize multi-threaded performance. The Core Ultra 5 250K Plus is the faster processor in the vast majority of tests. Its wins span Cinebench multicore, data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, physics, random string sorting, and single-thread PassMark tests. It also holds a higher average benchmark score of 66855, compared to the Core 7’s 40557, and sits in the 93rd percentile versus the Core 7’s 87th.

The Core 7 253PE has a specific niche. It wins Cinebench R23 single-core and Cinebench R15 single-core. Users running software that is heavily reliant on single-thread performance and compatible with those specific instruction paths may see an advantage with the Core 7. However, this advantage is narrow and does not extend to the more modern PassMark single-thread test, where the Ultra 5 is 16.9% faster. For any mixed or multi-threaded workload, the data indicates the Core Ultra 5 250K Plus is the stronger choice. The data also shows the Ultra 5 has a higher boost clock of 5.30 GHz compared to the Core 7’s 5.50 GHz, yet still wins the broader single-thread test, suggesting architectural efficiency plays a larger role than raw clock speed.

Memory support also differs. The Core 7 supports both DDR4 and DDR5 memory, while the Ultra 5 supports only DDR5. Both use a dual-channel memory bus, but the memory bandwidth is different. The Core 7 has a memory bandwidth of 89.6 GB/s, while the Ultra 5 has a higher bandwidth of 115.2 GB/s. Both support ECC memory. PCIe lanes are also different: the Core 7 provides Gen 5 with 16 Lanes (CPU only), while the Ultra 5 provides Gen 5 with 20 Lanes (CPU only). The integrated graphics differ, with the Core 7 featuring UHD Graphics 730 and the Ultra 5 featuring Arc Xe-LPG Graphics 64EU.

Architecture Differences

The architectural differences are substantial. The Intel Core 7 253PE is based on the Bartlett Lake codename and is built on a 10 nm process node by Intel. The Intel Core Ultra 5 250K Plus is based on the Arrow Lake Refresh codename and is built on a 3 nm process node by TSMC. The Ultra 5 also has a listed transistor count of 17,800 million and a die size of 243 mm², while the Core 7 does not have these figures recorded.

Cache hierarchies differ as well. The Core 7 has an L1 cache of 80 KB (per core), an L2 cache of 2 MB (per core), and a shared L3 cache of 33 MB. The Ultra 5 has a larger L1 cache of 192 KB (per core), a larger L2 cache of 3 MB (per core), but a smaller shared L3 cache of 30 MB. The Core 7 belongs to the Core 7 (Bartlett Lake) generation, while the Ultra 5 belongs to the Ultra 5 (Arrow Lake) generation and is part of the Core Ultra Series 2.

Where Each One Wins

The Intel Core 7 253PE wins in a narrow set of legacy single-threaded benchmarks. Its victories in Cinebench R15 single-core and Cinebench R23 single-core suggest it may hold an edge in older software that is not optimized for the newer architecture. This is despite having a lower base clock and a higher TDP efficiency rating.

The Intel Core Ultra 5 250K Plus wins in nearly all other scenarios. It is the clear choice for multi-threaded productivity, with decisive leads in all Cinebench multicore tests. Its performance in data compression, encryption, and extended instructions indicates strength in content creation, archival, and security-related tasks. The large lead in prime number finding and floating-point math points to advantages in scientific and simulation workloads. The higher PassMark single-thread score also makes it the better option for general responsiveness in modern applications. The Ultra 5’s higher memory bandwidth and support for more PCIe Gen 5 lanes further support its position for high-throughput systems. For any user whose workload extends beyond the specific legacy single-thread tests, the data shows the Core Ultra 5 250K Plus as the superior processor.
