Intel Core 7 253PQE vs Intel Core Ultra X7 358H Comparison

Head-to-Head Benchmarks

The benchmark data delivers a clear verdict: the Intel Core 7 253PQE dominates the Intel Core Ultra X7 358H in the vast majority of measured workloads. Out of 17 head-to-head comparisons, the Core 7 253PQE wins 14, while the Ultra X7 358H takes only 3. The average benchmark score gap is substantial, with the Core 7 253PQE posting 55919 against 40967 for the Ultra X7 358H, a difference that places the two processors in different performance tiers entirely.

The largest single-core margin appears in Cinebench R23 single-core, where the Core 7 253PQE scores 4431 against 2080 for the Ultra X7 358H, a 113% advantage. That is more than double the score, and it reflects the Core 7 253PQE's 5.70 GHz boost clock against the Ultra X7 358H's 4.80 GHz. The Cinebench R15 single-core test shows a similar pattern, with the Core 7 253PQE winning 446 to 301.5, a 47.9% delta. Cinebench R20 single-core is closer but still decisive: 1861 versus 1695, a 9.8% lead.

Multi-core results are equally lopsided in the Cinebench suite. Cinebench R23 multi-core shows the Core 7 253PQE at 31390 versus 18747, a 67.4% advantage. Cinebench R20 multi-core gives the Core 7 253PQE a 13183 to 12011 win, 9.8% ahead. Cinebench R15 multi-core is the closest of the three, with the Core 7 253PQE ahead 3163 to 3027, a 4.5% margin. The consistent multi-core lead is notable because the Ultra X7 358H actually has more physical cores (16 versus 10), but the Core 7 253PQE counters with 20 threads against 16 and a significantly higher base clock of 3.50 GHz versus 1.90 GHz.

PassMark integer math shows one of the biggest deltas: 137795 for the Core 7 253PQE versus 83147 for the Ultra X7 358H, a 65.7% lead. Data compression follows at 487335 versus 332508, a 46.6% margin. Random string sorting goes to the Core 7 253PQE at 54222 against 40357, 34.4% ahead. The multithread score is 41656 versus 33802, a 23.2% win. Extended instructions favor the Core 7 253PQE at 32390 versus 27274, an 18.8% edge. Single-thread PassMark results are closer, 4389 versus 4124, a 6.4% lead for the Core 7 253PQE. Floating point math is nearly even, with the Core 7 253PQE at 105279 against 103842, only 1.4% ahead.

The Ultra X7 358H takes its three wins in narrower, more specialized tests. PassMark find prime numbers goes to the Ultra X7 358H at 337 versus 206, a 38.9% advantage. Data encryption is a slim win at 26046 versus 25515, a 2% edge. Physics is also close, 3021 versus 2970, a 1.7% margin. These wins show that the Ultra X7 358H has specific strengths in prime number calculation and encryption workloads, but they do not offset the broad performance gap elsewhere.

The percentile ranking reinforces the split: the Core 7 253PQE sits at the 91st percentile among all CPUs, while the Ultra X7 358H ranks at the 87th percentile. The nearest rivals for the Core 7 253PQE are the Intel Core i9-14900HX at 56004 average score (0.2% higher), the AMD Ryzen AI Max 390 at 56273 (0.6% higher), the AMD Ryzen AI 9 HX PRO 470 at 56306 (0.7% higher), and the AMD Ryzen Threadripper PRO 3955WX at 56555 (1.1% higher). The Ultra X7 358H sits near the AMD Ryzen AI 5 PRO 440 at 41208 (0.6% higher), the Intel Core Ultra 7 356H at 41215 (0.6% higher), the AMD Ryzen AI 5 PRO 435G at 40718 (0.6% lower), and the Intel Core Ultra 7 366H at 41263 (0.7% higher). The Core 7 253PQE competes with high-end desktop and workstation parts, while the Ultra X7 358H trades blows with mid-range mobile processors.

Where Each One Wins

The Core 7 253PQE is the clear choice for compute-heavy, multi-threaded tasks. Its Cinebench R23 multi-core score of 31390 and PassMark multithread score of 41656 show it handles sustained parallel workloads with authority. Integer math at 137795 is a standout, and data compression at 487335 indicates strong performance for archiving, database operations, and file handling. The 33 MB shared L3 cache and 20 threads give it an advantage in workloads that benefit from large working sets and high thread counts.

Single-core responsiveness also belongs to the Core 7 253PQE. The Cinebench R23 single-core score of 4431 is more than double the Ultra X7 358H's 2080, and the Cinebench R15 single-core result of 446 versus 301.5 confirms the gap. The 5.70 GHz boost clock is the key factor here, and it shows in application launch times, spreadsheet recalculations, and lightly threaded productivity software. The 91st percentile ranking places it among the top tier of all CPUs in the database.

The Ultra X7 358H has a narrower but real set of strengths. Prime number finding at 337 versus 206 is a 38.9% win, which matters for certain mathematical workloads and cryptography-related calculations. Data encryption at 26046 edges out the Core 7 253PQE's 25515, indicating competitive performance in encryption and decryption tasks. The physics score of 3021 is marginally better than 2970, a slim but measurable advantage. Its 3 nm process node and 16 physical cores (without hyper-threading) deliver efficiency-oriented performance, and the 153.6 GB/s memory bandwidth is notably higher than the Core 7 253PQE's 89.6 GB/s, which helps in memory-bound scenarios. The integrated Arc B390 graphics also set it apart, though graphics performance is not covered by the benchmark data here.

The Verdict

The data directs different users to different processors. The Intel Core 7 253PQE is the performance leader in almost every measured category, with 14 wins out of 17 head-to-head tests. Its 67.4% lead in Cinebench R23 multi-core and 113% lead in Cinebench R23 single-core are decisive. Users running rendering, compilation, data analysis, or any workload that scales across threads should look at the Core 7 253PQE. Its 91st percentile ranking and average score of 55919 place it in the same bracket as the Intel Core i9-14900HX and AMD Ryzen AI Max 390, both of which sit within 0.6% of its average score.

The Intel Core Ultra X7 358H is a different proposition. Its 87th percentile ranking and average score of 40967 put it in the range of the AMD Ryzen AI 5 PRO 440 and Intel Core Ultra 7 356H, all within 0.7% of its average score. It wins in prime number calculation, data encryption, and physics, and it offers a 3 nm process node, 16 physical cores, and higher memory bandwidth. Users prioritizing those specific workloads, or needing a 25 W TDP mobile part with LPDDR5X memory support and Arc B390 graphics, will find it suitable. The Core 7 253PQE carries a 125 W TDP, so it is not a direct substitute in power-constrained mobile designs.

The Core 7 253PQE is the stronger processor by the recorded data. The Ultra X7 358H is the more efficient and specialized option, but it does not match the Core 7 253PQE in overall compute performance.
