Intel Core 7 253PE vs Intel Core Ultra 7 270HX Plus Comparison

The Verdict

The benchmark data presents a decisive outcome. The Intel Core Ultra 7 270HX Plus wins all 17 recorded head-to-head comparisons against the Intel Core 7 253PE. There are no benchmark categories where the Core 7 253PE takes a single win. The average benchmark score reflects this dominance: the Core Ultra 7 270HX Plus records an average of 61,834, while the Core 7 253PE averages 40,557. This places the Ultra 7 in the 93rd percentile of all CPUs in the database, compared to the 87th percentile for the Core 7.

The Core Ultra 7 270HX Plus also sits alongside much more powerful company. Its nearest rivals include the Intel Core i9-13900KF at an average score of 61,841, with a delta of 0%, and the Intel Core i9-13900K at 61,766 with a delta of 0.1%. The Core 7 253PE, by contrast, is grouped with the Intel Core 5 223PE at 40,585, a delta of -0.1%, and the AMD Ryzen 9 7940H at 40,431, a delta of 0.3%. The data indicates that the Core Ultra 7 270HX Plus competes in a higher performance class entirely.

For a user selecting between these two, the data points exclusively to the Core Ultra 7 270HX Plus. It delivers substantially higher scores in every single-core, multi-core, and specialized workload category recorded. The only caveat in the database is structural: the Core 7 253PE is a desktop part on Intel Socket 1700, while the Core Ultra 7 270HX Plus is a mobile part on Intel BGA 2114, so the platform choice will be dictated by the system form factor. Within the measured performance metrics, there is no scenario where the Core 7 253PE is the stronger processor.

Architecture Differences

The two processors come from different architectural lineages. The Intel Core 7 253PE uses the Bartlett Lake codename, built on a 10 nm process node at Intel's own foundry. The Intel Core Ultra 7 270HX Plus belongs to the Core Ultra Series 2, using the Arrow Lake-HX Refresh codename, and is manufactured on a 3 nm process node at TSMC. The transistor counts and die sizes are not recorded for the Bartlett Lake part, but the Arrow Lake-HX Refresh chip carries 17,800 million transistors across a 243 mm² die.

Core counts differ sharply. The Core 7 253PE has 10 cores and 20 threads. The Core Ultra 7 270HX Plus has 20 cores and also 20 threads. That means the Ultra 7 has double the physical cores but the same thread count, which implies a different core topology: the 20-core part likely uses a mix of performance and efficiency cores without hyper-threading on the performance cores, while the 10-core part achieves 20 threads through simultaneous multithreading. The database does not specify the core type split, but the thread-to-core ratio is a key structural distinction.

Cache hierarchies also diverge. The Core 7 253PE has an L1 cache of 80 KB per core, an L2 of 2 MB per core, and 33 MB of shared L3. The Core Ultra 7 270HX Plus has a larger L1 at 192 KB per core, a larger L2 at 3 MB per core, but a slightly smaller shared L3 at 30 MB. The larger per-core caches on the Ultra 7 align with its higher core count and newer process node.

Clock speeds show a mixed picture. The Core 7 253PE has a base clock of 2.50 GHz and a boost clock of 5.50 GHz. The Core Ultra 7 270HX Plus has a lower base clock of 2.40 GHz and a lower boost of 5.30 GHz. Despite the lower clocks, the Ultra 7 wins every benchmark, which points to architectural efficiency and the 3 nm process giving it an advantage in instructions per clock. The Core 7 253PE has a TDP of 65 watts, while the mobile Ultra 7 has a TDP of 55 watts, meaning the faster part also carries a lower power envelope in the recorded specifications.

Memory support differs as well. The Core 7 253PE supports both DDR4 and DDR5, while the Core Ultra 7 270HX Plus supports DDR5 only. Both use dual-channel memory buses. The memory bandwidth is higher on the Ultra 7 at 102.4 GB/s versus 89.6 GB/s on the Core 7. ECC memory is supported on the Core 7 253PE but not on the Core Ultra 7 270HX Plus. PCIe lanes also differ: the Core 7 provides Gen 5 with 16 lanes, while the Ultra 7 provides Gen 5 with 20 lanes. The integrated graphics are different models, with the Core 7 using UHD Graphics 730 and the Ultra 7 using Arc Xe-LPG Graphics 64EU. The Core 7 253PE has a locked multiplier, while the Core Ultra 7 270HX Plus has an unlocked multiplier.

Head-to-Head Benchmarks

The Cinebench results show a consistent 40.6% deficit for the Core 7 253PE across all six recorded Cinebench tests. In Cinebench R23 multi-core, the Core Ultra 7 270HX Plus scores 41,913 against 24,880 for the Core 7. In R23 single-core, the Ultra 7 scores 5,917 against 3,512. The same 40.6% gap appears in R15 multi-core (4,224 versus 2,507), R15 single-core (596 versus 354), R20 multi-core (17,603 versus 10,449), and R20 single-core (2,485 versus 1,475). This uniformity across single and multi-core tests suggests the Ultra 7's advantage is not just about core count but also about per-core performance.

The Passmark suite reveals a wider range of deltas. The smallest gap is in integer math, where the Ultra 7 scores 122,449 against 114,158, a margin of only 6.8%. This is the closest contest in the entire comparison. Single-thread performance also shows a relatively modest gap: 4,764 versus 3,955, a 17% deficit for the Core 7. The largest gap appears in find prime numbers, where the Ultra 7 scores 482 against 138, a 71.4% deficit for the Core 7. Floating point math shows a 50.6% gap (163,567 versus 80,870), and physics shows a 52% gap (3,843 versus 1,845).

Data-oriented workloads also favor the Ultra 7 heavily. Data compression scores 493,179 versus 339,133, a 31.2% gap. Data encryption scores 37,813 versus 18,385, a 51.4% gap. Extended instructions score 39,283 versus 21,806, a 44.5% gap. Random string sorting scores 60,020 versus 32,777, a 45.4% gap. The multithread Passmark score is 48,270 versus 29,271, a 39.4% gap.

The pattern that emerges is that the Ultra 7's advantage grows with workload complexity and parallelism. Integer math, which scales relatively predictably with core count and clock speed, shows the smallest gap. Prime number finding, which can benefit from specific instruction sets and cache behavior, shows the largest. The consistent 40.6% Cinebench gap across both single and multi-core tests is notable because it suggests the per-core architectural uplift is roughly equal to the multi-core scaling advantage.

Where Each One Wins

The Intel Core Ultra 7 270HX Plus wins every recorded benchmark category. There are no wins for the Intel Core 7 253PE in the head-to-head data. The closest margin is in Passmark integer math, where the Ultra 7 leads by only 6.8%, suggesting that the Core 7 253PE is comparatively stronger in basic arithmetic throughput relative to its overall performance profile. The largest margin is in find prime numbers, where the Ultra 7 leads by 71.4%, indicating a major advantage in workloads that stress number-theoretic computation.

For single-threaded performance, the Ultra 7 leads by 17% in Passmark single-thread and by 40.6% in all Cinebench single-core tests. This means the Ultra 7 is not just a multi-core monster; it also has superior per-core performance despite its lower boost clock. The Core 7 253PE's higher boost clock of 5.50 GHz does not translate into a win in any single-core test, which points to the Ultra 7's architectural efficiency on the 3 nm node.

For multi-threaded workloads, the Ultra 7 leads by 40.6% in Cinebench multi-core and by 39.4% in Passmark multithread. The doubled core count combined with the per-core advantage compounds into a substantial overall lead. The Core 7 253PE's only structural advantages are its larger L3 cache (33 MB versus 30 MB), its ECC memory support, its dual memory type support (DDR4 and DDR5), and its desktop platform with a lower base clock but higher boost. None of these translate into a benchmark win.

The use-case split is therefore straightforward. For any workload represented in the database, the Core Ultra 7 270HX Plus is the faster processor. The Core 7 253PE retains relevance only for users who specifically need the desktop Socket 1700 platform, ECC memory support, or DDR4 compatibility. In pure performance terms, the data shows no scenario where the Core 7 253PE comes out ahead.
