Intel Core 5 320 vs Intel Core 7 253PE Comparison

Where Each One Wins

The benchmark data splits this comparison into two very different profiles. The Intel Core 7 253PE wins 15 of the 17 recorded head-to-head tests, while the Intel Core 5 320 wins only 2. Those two wins, however, are both in single-threaded PassMark tests, where the Core 5 320 scores 4045 against 3955 for the Core 7 253PE, a margin of 2.3%. That is the only category where the smaller processor leads.

The Core 7 253PE dominates every multi-core workload in the database. In Cinebench R23 multicore, it scores 24880 versus 6197, a 75.1% advantage. In PassMark integer math, the gap widens to 71.7%, with scores of 114158 against 32323. Data compression shows a 56.1% lead at 339133 versus 148779. The Core 7 253PE also wins floating point math at 80870 versus 42440, a 47.5% margin, and multithreaded PassMark at 29271 versus 15450, a 47.2% margin.

The single-core Cinebench tests also favor the Core 7 253PE, despite the PassMark single-thread result going the other way. Cinebench R23 single-core shows 3512 for the Core 7 253PE against 1926 for the Core 5 320, a 45.2% lead. Cinebench R20 single-core shows 1475 versus 771, a 47.7% margin. Cinebench R15 single-core shows 354 versus 276, a 22% margin. So the Core 5 320 does not win universally in single-threaded work; it wins specifically in the PassMark single-thread measurement while losing the Cinebench single-core tests by substantial margins.

The use-case split is therefore clear. The Core 7 253PE is the processor for heavily threaded workloads: rendering, encryption, compression, math-heavy tasks, and any application that scales across cores. The Core 5 320 has a narrow niche in the PassMark single-thread metric, where it edges ahead by 2.3%, but that advantage does not carry over to Cinebench single-core tests.

The Verdict

The data indicates that the Intel Core 7 253PE is the stronger processor in nearly every measured dimension. Its average benchmark score of 40557 places it in the 87th percentile of all CPUs in the database, while the Core 5 320 averages 18023 and sits in the 72nd percentile. The nearest rivals for the Core 7 253PE include the Intel Core 5 223PE at 40585, a 0.1% difference, the Intel Core Ultra X7 368H at 40518, a 0.1% difference, and the AMD Ryzen 9 7940H at 40431, a 0.3% difference. The Core 5 320, by contrast, sits near the AMD Ryzen 5 1600 at 17994, a 0.2% difference, and the Intel Core i5-1334U at 18154, a 0.7% difference.

For workloads that use multiple cores, the Core 7 253PE is the clear choice. Its 10 cores and 20 threads, combined with a 5.50 GHz boost clock and 33 MB of shared L3 cache, deliver results that the 6-core, 6-thread Core 5 320 cannot approach. The Core 7 253PE leads by 75.1% in Cinebench R23 multicore and by 71.7% in PassMark integer math, margins that dwarf the Core 5 320's single PassMark single-thread win.

The Core 5 320 does have one measurable advantage: the PassMark single-thread score of 4045 versus 3955. For applications that rely on that specific metric, the Core 5 320 is ahead, but by only 2.3%. That is a narrow edge, and it does not appear in the Cinebench single-core tests, where the Core 7 253PE leads by 22% to 47.7% depending on the test version.

The production status of both processors is Active. The Core 7 253PE is a desktop part on Intel Socket 1700, while the Core 5 320 is a mobile part on Intel BGA 1516. They are not interchangeable in a system, so the choice is also a platform choice. The data shows that the Core 7 253PE is the higher-performing option across the board, with the Core 5 320 holding a single narrow single-thread lead.

Head-to-Head Benchmarks
