Intel Core 7 253PQE vs Intel Core Ultra 5 225H Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core 7 253PQE and the Intel Core Ultra 5 225H shows a decisive performance advantage for the desktop part in nearly every measured workload. The Core 7 253PQE wins 16 of the 17 head-to-head tests, with the Core Ultra 5 225H taking only a single narrow victory.

The most dramatic gap appears in the Cinebench R23 tests. In the multi-core test, the Core 7 253PQE scores 31,390 against 14,629.5 for the Core Ultra 5 225H, a 114.6% advantage. The single-core R23 result is even more lopsided: 4,431 versus 1,969, a 125% delta. These are the largest percentage differences in the entire comparison, indicating that the Core 7 253PQE holds a substantial lead in both heavily threaded and lightly threaded rendering workloads.

The Cinebench R15 and R20 results follow a similar pattern, though with smaller margins. In R15 multi-core, the Core 7 253PQE scores 3,163 against 2,397.5, a 31.9% lead. The R15 single-core test shows a 54.6% advantage (446 versus 288.5). R20 multi-core and single-core both show exactly 31.3% deltas, with scores of 13,183 versus 10,041 and 1,861 versus 1,417 respectively.

PassMark integer math reveals another massive gap. The Core 7 253PQE scores 137,795 versus 68,520 for the Core Ultra 5 225H, a 101.1% difference. This nearly doubles the throughput in integer-heavy calculations. Floating-point math shows a smaller but still significant 21.7% lead (105,279 versus 86,540). Data compression also favors the Core 7 253PQE by 71.9% (487,335 versus 283,451), while extended instruction throughput shows a 47.8% advantage (32,390 versus 21,915).

Multithreaded performance in PassMark delivers a 48.1% delta (41,656 versus 28,119), while the physics test shows a 58.2% lead (2,970 versus 1,877). Random string sorting favors the Core 7 253PQE by 61.1% (54,222 versus 33,654). Data encryption shows a more modest 19.1% gap (25,515 versus 21,428).

Single-thread performance in PassMark is the closest contest. The Core 7 253PQE scores 4,389 versus 4,258, a mere 3.1% margin. This near parity in single-threaded PassMark results contrasts sharply with the larger single-core gaps in the Cinebench tests. The Core Ultra 5 225H manages its only win in the find prime numbers test, scoring 220 against 206, a 6.4% edge in that specific workload.

Architecture Differences

The two processors come from fundamentally different design families. The Intel Core 7 253PQE uses the Bartlett Lake architecture built on a 10 nm process at Intel's own foundry. It belongs to the Core 7 generation and targets the desktop segment with an Intel Socket 1700 package. The Core Ultra 5 225H uses the Arrow Lake architecture on a 3 nm process fabricated by TSMC, belonging to the Core Ultra Series 2 family and designed for mobile systems with an Intel BGA 2049 socket.

Core and thread counts differ significantly. The Core 7 253PQE has 10 cores and 20 threads, while the Core Ultra 5 225H has 14 cores but only 14 threads. This means the desktop part enables simultaneous multithreading on all its cores, whereas the mobile part runs all threads as independent physical threads without SMT. The higher thread count of the Core 7 253PQE contributes to its strong multi-core results despite having fewer physical cores.

Clock speeds also diverge sharply. The Core 7 253PQE has a base clock of 3.50 GHz and boosts to 5.70 GHz. The Core Ultra 5 225H runs at a much lower 1.70 GHz base and boosts to 4.90 GHz. The higher boost clock of the desktop part explains its substantial single-core advantages in Cinebench tests.

Cache configurations differ across all levels. The Core 7 253PQE has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Core Ultra 5 225H has larger per-core caches at 192 KB L1 and 3 MB L2, but a smaller 18 MB shared L3. The larger L3 on the desktop part likely contributes to its performance in cache-sensitive workloads like data compression and random string sorting.

Memory support and bandwidth also differ. The Core 7 253PQE supports DDR4 and DDR5 memory with dual-channel operation and 89.6 GB/s bandwidth. The Core Ultra 5 225H supports DDR5 and LPDDR5X with dual-channel operation and higher bandwidth at 102.4 GB/s. The mobile part also lacks ECC memory support, while the desktop part includes it.

PCIe connectivity shows another distinction. The Core 7 253PQE provides Gen 5 with 16 CPU lanes, while the Core Ultra 5 225H provides Gen 5 with only 8 CPU lanes. Integrated graphics differ as well: the desktop part uses UHD Graphics 770, while the mobile part uses Arc Graphics 130T.

FAQ

Q: Which processor has a higher thread count?

A: The Intel Core 7 253PQE has 20 threads, while the Intel Core Ultra 5 225H has 14 threads. The desktop part achieves this with 10 cores using simultaneous multithreading, whereas the mobile part has 14 physical cores but no SMT.

The Verdict

The recorded data shows a clear performance hierarchy between these two processors. The Intel Core 7 253PQE delivers superior results in 16 of 17 benchmark comparisons, with margins ranging from a narrow 3.1% in PassMark single-thread to a dominant 125% in Cinebench R23 single-core. The average benchmark score of 55,919 versus 31,508 places the desktop part in the 91st percentile of all CPUs, compared to the 82nd percentile for the mobile part.

The Core Ultra 5 225H holds advantages in energy efficiency, with a 28 watt TDP versus 125 watts, and in memory bandwidth at 102.4 GB/s versus 89.6 GB/s. It also uses a smaller 3 nm process node compared to 10 nm. However, these advantages do not translate into benchmark wins. The only victory for the mobile part is a 6.4% edge in the find prime numbers test.

For users who prioritize raw computational throughput, the Core 7 253PQE is the clear choice from the benchmark data. Its higher boost clock, larger L3 cache, and doubled thread count deliver substantial wins in rendering, integer math, compression, and multithreaded workloads. The Core Ultra 5 225H suits environments where low power consumption and compact mobile packaging matter more than peak performance, though the data indicates it trails significantly in almost every measured task.
