Intel Core i5-14401E vs Intel Core Ultra 5 336H Comparison

Intel Core i5-14401E is a desktop part built on Intel's Raptor Lake architecture, while the Intel Core Ultra 5 336H is a mobile processor using the newer Panther Lake design. The benchmark data shows a clear overall winner in the Core Ultra 5 336H, which wins every recorded Cinebench test, but the two chips serve very different physical markets. The i5-14401E uses the LGA 1700 socket for desktop builds, while the Ultra 5 336H uses the BGA 2540 socket and is designed for laptops.

Where Each One Wins

The data records no wins for the Intel Core i5-14401E in the head-to-head benchmarks. Across all six Cinebench tests, the Intel Core Ultra 5 336H takes every single victory. The closest margin appears in the single-core tests, but even there the Ultra 5 336H maintains a consistent 24.3% lead in every comparison, from Cinebench R15 single-core to Cinebench R23 multi-core.

The Core Ultra 5 336H also holds the advantage in the broader database metrics. It sits in the 84th percentile of all CPUs, while the Core i5-14401E sits in the 60th percentile. The average benchmark score tells the same story: the Ultra 5 336H records 34485, while the i5-14401E records 5253. That gap reflects the different benchmark suites available for each chip, but the percentile placement confirms the Ultra 5 336H is the stronger performer overall.

The Core i5-14401E does not win any recorded category. Its only advantages are structural: it is a desktop chip with a 65 W TDP, an LGA 1700 socket, and support for DDR4 memory. Those traits do not show up as benchmark wins, but they matter for a builder choosing a platform. The data shows the i5-14401E is the only one of the two with ECC memory support and the only one that can use DDR4.

Cinebench R23 shows the largest absolute margins. The Ultra 5 336H scores 23991 in multi-core, while the i5-14401E scores 18161. In single-core, the Ultra 5 336H scores 3387, while the i5-14401E scores 2564.

The consistency of the 24.3% delta across every test is notable. It suggests the performance gap is not workload-specific but reflects a general processing advantage for the Ultra 5 336H. The nearest rival data supports this. The Ultra 5 336H sits within 0.8% of the AMD Ryzen AI 7 350 and 0.7% of the AMD Ryzen 7 3700X, while the i5-14401E sits within 0.8% of the Intel Core i5-13400T and 0.2% of the Intel Core i9-10850K. These positions confirm the Ultra 5 336H competes in a higher performance tier.

The Verdict

The benchmark data points clearly to the Intel Core Ultra 5 336H as the stronger processor. It wins every recorded Cinebench test by 24.3%, occupies the 84th percentile of all CPUs, and averages 34485 in the database. The Core i5-14401E, by contrast, wins no recorded tests and sits in the 60th percentile.

The choice depends on platform. The Core Ultra 5 336H is a mobile processor with a 25 W TDP, a BGA 2540 socket, and support for DDR5 and LPDDR5X. It belongs in a laptop. The Core i5-14401E is a desktop processor with a 65 W TDP, an LGA 1700 socket, and support for DDR4 and DDR5. It belongs in a desktop build.

For a desktop builder, the i5-14401E offers ECC memory support and a 16-lane Gen 5 PCIe connection, neither of which the Ultra 5 336H provides. For anyone comparing raw benchmark performance, the Ultra 5 336H is ahead in every recorded metric. The data does not record a single test where the i5-14401E comes out on top.
