Intel Core 7 253PQE vs Intel Core Ultra 3 105UL Comparison

Head-to-Head Benchmarks

The benchmark data presents an unambiguous performance hierarchy between these two processors. Across all 17 recorded head-to-head tests, the Intel Core 7 253PQE wins every single comparison. The magnitude of that lead, however, varies dramatically depending on the workload type.

In the Cinebench suite, the Core 7 253PQE consistently delivers roughly 259% higher scores. Cinebench R23 multi-core shows a score of 31390 against 8742, while the single-core test records 4431 versus 1234. The R15 and R20 results follow the same pattern: multi-core scores of 3163 versus 881 and 13183 versus 3671 respectively, with single-core scores of 446 versus 124 and 1861 versus 518. The deltas across all six Cinebench tests cluster tightly between 259.1% and 259.7%, indicating that the Core 7 253PQE's advantage is consistent regardless of render complexity.

The PassMark suite reveals where the architectural gap widens further. Data compression shows the largest proportional margin in integer-heavy work at 418.7%, with scores of 487335 against 93961. Extended instructions produce the single largest delta of 474.9% (32390 versus 5634). Random string sorting runs 385% ahead (54222 versus 11179), and prime number finding shows a 368.2% advantage (206 versus 44). Data encryption records a 301.6% lead (25515 versus 6354), while the multithread test shows 41656 versus 10285, a 305% margin.

The narrowest gap appears in PassMark's single-thread test, where the Core 7 253PQE scores 4389 against 3382, a 29.8% advantage. This is the only benchmark where the Ultra 3 105UL comes within striking distance, which suggests that per-clock efficiency differences are modest; the massive multi-thread gaps stem primarily from core count, thread count, and clock speed.

Floating-point math and integer math show deltas of 242.4% and 234.7% respectively, with scores of 105279 versus 30750 and 137795 versus 41171. Physics simulation records 2970 against 718, a 313.6% margin. The average benchmark score for the Core 7 253PQE is 55919, which places it in the 91st percentile of all CPUs. The Ultra 3 105UL averages 13061, sitting in the 68th percentile.

Architecture Differences

The two processors diverge sharply in their foundational design. The Intel Core 7 253PQE uses the Bartlett Lake codename on a 10 nm process, while the Intel Core Ultra 3 105UL belongs to the Meteor Lake-PS family on a 7 nm node. Both are manufactured by Intel, but they target entirely different power envelopes: the Core 7 253PQE carries a 125 W TDP, whereas the Ultra 3 105UL operates at just 15 W.

Core configuration differs substantially. The Core 7 253PQE provides 10 cores and 20 threads, while the Ultra 3 105UL offers 8 cores and 10 threads. This means the Core 7 253PQE supports hyper-threading across all cores, while the Ultra 3 105UL effectively has two fewer threads than its core count would suggest if fully threaded, indicating a hybrid core arrangement where only two cores add extra threads.

Clock speeds reinforce the performance gap. The Core 7 253PQE has a base clock of 3.50 GHz and a boost clock of 5.70 GHz. The Ultra 3 105UL runs at 1.50 GHz base and 4.20 GHz boost. The 2.0 GHz base clock deficit and 1.5 GHz boost deficit explain much of the single-thread performance difference, though the 29.8% single-thread margin shows that clock alone does not fully account for the gap.

Cache hierarchies also favor the Core 7 253PQE heavily. It features 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Ultra 3 105UL has 112 KB of L1 per core, which is actually larger, but only 2 MB of L2 per core and 10 MB of shared L3. The 23 MB L3 deficit is significant for workloads that repeatedly access large datasets.

Platform support differs across every major interface. The Core 7 253PQE uses Intel Socket 1700 and supports both DDR4 and DDR5 memory, while the Ultra 3 105UL uses Intel Socket 1851 and supports DDR5 only, with capacity depending on the motherboard. Both run dual-channel memory at 89.6 GB/s bandwidth. ECC memory is supported on the Core 7 253PQE but not on the Ultra 3 105UL. PCIe connectivity also diverges: the Core 7 253PQE provides Gen 5 with 16 CPU lanes, while the Ultra 3 105UL provides Gen 4 with 8 CPU lanes.

Integrated graphics differ as well. The Core 7 253PQE uses UHD Graphics 770, while the Ultra 3 105UL uses Arc Xe-LPG 48EU. Neither processor is multiplier-unlocked. The Core 7 253PQE launched on 2026-03-08 with a launch MSRP of $409. The Ultra 3 105UL launched on 2024-04-07 with a launch MSRP of $295.

Where Each One Wins

The Core 7 253PQE wins in every measured category, but the shape of its dominance points to specific strengths. The largest deltas appear in extended instructions, data compression, random string sorting, and prime number finding. These are all workloads that scale with core count, thread count, and cache capacity. The 33 MB L3 cache and 20 threads give it a clear advantage in parallel integer operations and data manipulation tasks. The multithread test result of 41656 against 10285 confirms that heavily parallel workloads see the biggest gains.

The smallest margin is in single-thread performance at 29.8%. This suggests that for lightly threaded applications, such as basic office tasks or legacy software that uses one core, the Ultra 3 105UL is comparatively less disadvantaged. The Ultra 3 105UL also has a larger L1 cache per core at 112 KB versus 80 KB, which may help in some latency-sensitive single-thread scenarios, though the recorded data does not isolate that effect.

The Ultra 3 105UL's 15 W TDP means it fits into power-constrained systems where the 125 W Core 7 253PQE cannot operate. The data shows no benchmark where the Ultra 3 105UL leads, so its case rests entirely on platform compatibility and power envelope, not on measured performance. The Core 7 253PQE sits in the 91st percentile of all CPUs and its nearest rivals include the Intel Core i9-14900HX at a 0.2% higher average score, the AMD Ryzen AI Max 390 at 0.6% higher, the AMD Ryzen AI 9 HX PRO 470 at 0.7% higher, and the AMD Ryzen Threadripper PRO 3955WX at 1.1% higher. The Ultra 3 105UL, by contrast, sits near the Intel Core i5-9400F, Intel Core i7-10750H, Intel Core i5-8500, and Intel Core i7-7700K, with deltas no larger than 1.7%.

The Verdict

The recorded data supports only one performance conclusion: the Intel Core 7 253PQE is dramatically faster than the Intel Core Ultra 3 105UL in every measured workload. The 259% Cinebench margins and the 234.7% to 474.9% PassMark deltas leave no ambiguity. The Core 7 253PQE's 10 cores, 20 threads, 5.70 GHz boost clock, and 33 MB of L3 cache position it for demanding multi-threaded desktop workloads, and its 91st percentile standing among all CPUs confirms that.

The Intel Core Ultra 3 105UL, with its 8 cores, 10 threads, 4.20 GHz boost clock, and 10 MB of L3 cache, occupies the 68th percentile. Its nearest rivals are older mainstream parts like the Intel Core i7-7700K and Intel Core i5-8500, which places it in a different performance class entirely.

Selection between these two should follow from platform and power constraints rather than performance expectations. The Ultra 3 105UL operates at 15 W and uses Socket 1851, which suits compact or low-power desktop builds. The Core 7 253PQE requires a 125 W envelope and Socket 1700, which suits full-size desktop systems where performance is the priority. The data does not show any workload where the Ultra 3 105UL closes the gap, so buyers who need the Core 7 253PQE's performance level should not expect the Ultra 3 105UL to substitute. Buyers who need the Ultra 3 105UL's power profile should expect roughly one-quarter to one-fifth of the multi-threaded throughput, depending on the specific test.
