Intel Core 7 253PE vs Intel Core i9-14900KS Comparison

Intel Core 7 253PE and Intel Core i9-14900KS are both desktop processors on the Intel Socket 1700 platform, but they occupy very different positions in the market. The database records show a clear performance hierarchy, with the Core i9-14900KS winning all 17 recorded head-to-head benchmark comparisons. The Core 7 253PE holds a 65 W TDP and a launch MSRP of $384, while the Core i9-14900KS has a 150 W TDP and a launch MSRP of $689. This analysis examines the benchmark data, architectural differences, and specification gaps between the two parts.

Where Each One Wins

The Core i9-14900KS is the outright winner in every single benchmark category recorded in the database. It does not merely edge out the Core 7 253PE; it dominates across single-threaded, multi-threaded, and specialized workloads. The data shows no workload where the Core 7 253PE comes out ahead, making the use-case split straightforward: the Core i9-14900KS is the superior choice for any task where raw performance is the primary requirement.

The Core 7 253PE's role is defined by its efficiency and platform positioning rather than benchmark victories. With a 65 W TDP, it delivers substantial performance at a fraction of the power envelope of the 150 W Core i9-14900KS. Its percentile ranking of 87 means it outperforms 87% of all CPUs in the database, making it a strong performer in absolute terms. The Core i9-14900KS sits at the 96th percentile, but the Core 7 253PE remains a capable processor for builds where power draw is a limiting factor.

The single-threaded results show the smallest gap between the two, with the Core i9-14900KS leading by 17.9% in PassMark single-thread testing. This suggests that for lightly-threaded workloads, the Core 7 253PE is relatively closer to its larger sibling. However, the multi-threaded and specialized workloads reveal massive differences, with the Core i9-14900KS often doubling or nearly doubling the Core 7 253PE's output.

Architecture Differences

Both processors are built on Intel's 10 nm process node and use the same foundry, but their architectures diverge significantly. The Core 7 253PE uses the Bartlett Lake codename, listed as part of the Core 7 generation, while the Core i9-14900KS is based on Raptor Lake, specifically the Raptor Lake-R refresh. This architectural split explains much of the performance gap.

The Core i9-14900KS features a die size of 257 mm², whereas the Core 7 253PE has no recorded die size in the database. The Core i9-14900KS also carries a significantly larger L3 cache: 36 MB shared versus 33 MB shared on the Core 7 253PE. Both processors share the same L1 cache configuration of 80 KB per core and L2 cache of 2 MB per core, but the extra 3 MB of L3 cache on the Core i9-14900KS helps with larger working sets.

The core counts differ substantially. The Core i9-14900KS has 24 cores and 32 threads, while the Core 7 253PE has 10 cores and 20 threads. This 14-core difference is the primary driver of multi-threaded benchmark results. The Core i9-14900KS also has a higher base clock of 3.20 GHz versus 2.50 GHz, and a higher boost clock of 6.20 GHz versus 5.50 GHz. The multiplier is unlocked on the Core i9-14900KS, allowing overclocking, while the Core 7 253PE has a locked multiplier.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern of the Core i9-14900KS leading by 51.2% across all six tests. In Cinebench R15 multi-core, the Core i9-14900KS scores 5140 versus 2507 for the Core 7 253PE. The single-core result is 725 versus 354, a similar percentage gap. Cinebench R20 shows 21417 versus 10449 in multi-core and 3023 versus 1475 in single-core. Cinebench R23 repeats the pattern with 50995 versus 24880 in multi-core and 7199 versus 3512 in single-core.

The PassMark suite reveals the widest margins. The largest gap is in random string sorting, where the Core i9-14900KS scores 89789 versus 32777, a 63.5% difference. Data encryption shows a 61.5% gap with 47717 versus 18385. Data compression follows at 57.8% with 803368 versus 339133. Extended instructions show a 52.1% gap with 45524 versus 21806. The multi-thread benchmark shows 60012 versus 29271, a 51.2% difference.

The smallest gap in the entire dataset is in PassMark single-thread testing, where the Core i9-14900KS scores 4815 versus 3955, a 17.9% difference. Other PassMark workloads show gaps between 43.4% and 47.5%. Find prime numbers shows 244 versus 138, a 43.4% gap. Physics shows 3381 versus 1845, a 45.4% gap. Integer math shows 212644 versus 114158, a 46.3% gap. Floating point math shows 153975 versus 80870, a 47.5% gap.

The Core i9-14900KS also has two Geekbench results in its benchmark list that the Core 7 253PE does not have: a multi-core score of 23931 and a single-core score of 2692. These additional benchmarks were not part of the head-to-head comparison, but they contribute to the Core i9-14900KS's average benchmark score of 81127, compared to 40557 for the Core 7 253PE.
