AMD Ryzen 5 40 vs Intel Core i5-14401E Comparison

The AMD Ryzen 5 40 and Intel Core i5-14401E serve entirely different market segments, one being a mobile processor built for efficiency and the other a desktop part aimed at sustained performance. The benchmark data confirms a decisive performance gap, with the Intel chip winning every head-to-head test recorded in the database.

Head-to-Head Benchmarks

The Intel Core i5-14401E dominates the recorded benchmarks, winning all four shared tests. The largest margin appears in the multi-core Cinebench R23 test, where the Intel part scores 18,161 against the AMD Ryzen 5 40's 4,841, a delta of -73.3%. This result indicates that the Intel processor delivers more than three times the multi-threaded rendering performance, a gap that reflects both a higher core count and a substantially higher power envelope.

In the single-core Cinebench R23 test, the Intel part scores 2,564 versus 1,150 for the AMD chip, a difference of -55.1%. This confirms that even on a per-thread basis, the Raptor Lake architecture holds a significant advantage over the Zen 2-based Mendocino design. The older Cinebench R15 tests follow the same pattern. In the multi-core R15 test, Intel scores 1,830 against AMD's 790, a delta of -56.8%. In the single-core R15 test, Intel scores 258 versus 165.5, a delta of -35.9%.

The database also includes additional Cinebench R20 scores for the Intel chip (7,627 multi-core and 1,076 single-core), but no corresponding AMD scores exist in the dataset for that test. The overall average benchmark score for the Intel Core i5-14401E is 5,253, while the AMD Ryzen 5 40 averages 15,882. This apparent inversion stems from the fact that the AMD chip has a much larger set of recorded PassMark tests, including data compression, encryption, and integer math, which inflate its average relative to the Intel part's limited Cinebench-only dataset. The Intel processor sits at the 60th percentile of all CPUs in the database, while the AMD chip sits at the 70th percentile, a ranking that again reflects the different test sets rather than raw performance parity.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 40 uses the Zen 2 architecture on a 6 nm process node fabricated by TSMC, with a die size of 100 mm². The Intel Core i5-14401E uses the Raptor Lake architecture on a 10 nm process node fabricated by Intel, with a die size of 215 mm². The Intel chip is a desktop part with a 65 W TDP, while the AMD chip is a mobile part with a 15 W TDP.

Core and thread counts differ significantly. The AMD chip has 4 cores and 8 threads, while the Intel chip has 6 cores and 12 threads. Cache hierarchies also diverge. The AMD chip provides 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel chip provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The larger L3 cache on the Intel part likely contributes to its strong single-thread performance in the recorded benchmarks.

Memory support differs as well. The AMD chip supports LPDDR5 memory on a dual-channel bus, with a recorded memory bandwidth of 88.0 GB/s. The Intel chip supports both DDR4 and DDR5 on a dual-channel bus, though no memory bandwidth figure appears in the database. The AMD chip does not support ECC memory, while the Intel chip does. PCIe connectivity also differs: the AMD chip uses Gen 3 with 4 CPU lanes, while the Intel chip uses Gen 5 with 16 CPU lanes.

The integrated graphics differ. The AMD chip includes Radeon 610M graphics, while the Intel chip includes UHD Graphics 730. The AMD chip uses the AMD Socket FT6, while the Intel chip uses Intel Socket 1700. The AMD chip is marked as a mobile segment part, while the Intel chip is a desktop segment part. Both are listed as active production, and neither has an unlocked multiplier.

The Verdict

The recorded data shows a clear performance hierarchy. The Intel Core i5-14401E wins all four head-to-head benchmark tests, with margins ranging from -35.9% in single-core Cinebench R15 to -73.3% in multi-core Cinebench R23. The Intel chip also carries double the cores, five times the L3 cache, a higher boost clock, and a 65 W TDP that allows sustained desktop workloads.

The AMD Ryzen 5 40, by contrast, offers a 15 W TDP, a smaller die size, and mobile segment positioning. Its advantage lies in efficiency and compactness, not raw performance. The database shows no benchmark test where the AMD chip wins, and its nearest rivals in the overall average score include server-class AMD EPYC parts and an Intel Core Ultra 5, which indicates that its recorded PassMark results place it in a different performance class than the Intel desktop chip.

For a desktop user with access to standard power delivery and cooling, the Intel Core i5-14401E is the only choice based on the recorded data. It delivers superior results in every measured workload, from single-threaded responsiveness to heavily threaded rendering. For a mobile or low-power application, the AMD Ryzen 5 40 offers a functional feature set with integrated Radeon 610M graphics and LPDDR5 memory support, but its benchmark scores suggest it cannot match the Intel part in performance-intensive tasks. The data does not support any scenario where the AMD chip outperforms the Intel chip, so the selection depends entirely on whether the use case prioritizes the Intel chip's performance or the AMD chip's low-power mobile design.
