Architecture Differences

The AMD Ryzen 5 7400 belongs to the 7000 series and is built on the Zen 4 architecture with the codename Raphael. It is manufactured on a 5 nm process at TSMC, featuring 6,570 million transistors on a 71 mm² die. The Intel Core i9-14901KE is part of the Core 14th Gen series, using the Raptor Lake architecture with the codename Raptor Lake-R, and is manufactured on Intel's 10 nm process with a die size of 257 mm². The transistor count for the Intel part is not recorded in the database.

The cache hierarchy reveals notable differences. The AMD chip provides 64 KB of L1 cache per core and 1 MB of L2 cache per core, with 16 MB of shared L3 cache. The Intel chip offers 80 KB of L1 cache per core and 2 MB of L2 cache per core, with a substantially larger 36 MB of shared L3 cache. This larger L3 capacity on the Intel side provides more room for frequently accessed data across its 8 cores.

Memory support also diverges. The AMD Ryzen 5 7400 supports only DDR5 memory over a dual-channel bus, with a recorded memory bandwidth of 83.2 GB/s. The Intel Core i9-14901KE supports both DDR4 and DDR5 memory over a dual-channel bus, though its memory bandwidth figure is not recorded in the database. Both processors support ECC memory.

PCIe connectivity differs as well. The AMD processor offers Gen 5 with 24 lanes (CPU only), while the Intel processor offers Gen 5 with 16 lanes (CPU only). Integrated graphics are present on both: the AMD chip includes Radeon Graphics, and the Intel chip includes UHD Graphics 770.

Socket compatibility separates the two platforms completely. The AMD Ryzen 5 7400 uses AMD Socket AM5, while the Intel Core i9-14901KE uses Intel Socket 1700. Both processors have unlocked multipliers, and both are listed as active production parts. The AMD part was released on 2025-09-15, while the Intel part was released on 2024-06-30.

The Verdict

The benchmark data in the database provides a clear picture for the AMD Ryzen 5 7400, which has an average benchmark score of 42,055 and sits at the 88th percentile among all CPUs. The Intel Core i9-14901KE, by contrast, has no recorded benchmark scores in the database, resulting in an average benchmark score of 0 and a 50th percentile ranking. This absence of recorded data means the Intel part cannot be directly compared on measured performance.

The AMD Ryzen 5 7400's nearest rivals in the database include the AMD Ryzen 9 PRO 8945HS at 41,963 (0.2% behind), the Intel Core i7-14700T at 41,914 (0.3% behind), the Intel Core i7-12850HX at 41,779 (0.7% behind), and the Intel Core i9-12900K at 42,335 (0.7% ahead). These figures place the Ryzen 5 7400 in a competitive band where small percentage differences separate adjacent processors.

Given the data, the AMD Ryzen 5 7400 is the only one of the two with verified performance measurements. Users requiring a lower-power desktop processor with a 65 W TDP, a 5 nm process, and AM5 platform compatibility would select the AMD part based on the recorded data. The Intel Core i9-14901KE offers a higher core count, higher clocks, and a larger cache, but the database contains no benchmark results to substantiate its performance level. The choice between them rests on platform preference and the need for the Intel part's specifications, not on measured benchmark comparisons.

Specification Differences

The two processors differ across nearly every recorded specification field. The AMD Ryzen 5 7400 has 6 cores and 12 threads; the Intel Core i9-14901KE has 8 cores and 16 threads. Base clocks are 3.30 GHz for the AMD part and 3.80 GHz for the Intel part, with boost clocks of 4.30 GHz and 5.80 GHz respectively.

TDP differs substantially: 65 W for the AMD chip versus 125 W for the Intel chip. Process technology also differs, with the AMD chip at 5 nm (TSMC) and the Intel chip at 10 nm (Intel). Die size is 71 mm² for AMD and 257 mm² for Intel. Transistor count is 6,570 million for AMD; no transistor count is recorded for Intel.

Cache layouts differ per core and in shared L3. The AMD chip has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel chip has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. Memory support: AMD uses DDR5 only with 83.2 GB/s bandwidth; Intel uses DDR4 and DDR5 with no bandwidth figure recorded. Both use dual-channel memory buses and support ECC.

PCIe configuration: AMD provides Gen 5 with 24 lanes (CPU only); Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics: AMD includes Radeon Graphics; Intel includes UHD Graphics 770. Sockets are AMD Socket AM5 versus Intel Socket 1700. Release dates are 2025-09-15 for AMD and 2024-06-30 for Intel. Both have unlocked multipliers and active production status. Neither processor has a launch MSRP recorded in the database.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the AMD Ryzen 5 7400 versus the Intel Core i9-14901KE. Consequently, there are no recorded wins for either processor in a direct comparison, and no individual test scores for the Intel part exist to analyze.

The AMD Ryzen 5 7400 does have a full set of recorded benchmark scores from the PassMark suite. Its single-thread score is 3,248, and its multi-thread score is 21,712. Other recorded results include integer math at 64,733, floating point math at 40,784, data compression at 261,749, data encryption at 14,865, extended instructions at 19,924, find prime numbers at 79, physics at 1,150, and random string sorting at 31,110. These scores contribute to its average benchmark score of 42,055.

The Intel Core i9-14901KE has no benchmark array entries in the database, no average benchmark score, and no nearest rivals. This makes any numerical performance comparison impossible. The only quantitative data available for the Intel part are its specifications: higher core count, higher base and boost clocks, larger cache, and higher TDP. Without measured scores, the database cannot confirm whether those specifications translate into performance advantages.

Where Each One Wins

Based solely on recorded data, the AMD Ryzen 5 7400 is the only processor with measurable benchmark wins. Its average benchmark score of 42,055 and 88th percentile ranking place it above the Intel Core i9-14901KE, which has no recorded scores and sits at the 50th percentile by default.

The AMD part wins on efficiency metrics: its 65 W TDP is nearly half the Intel part's 125 W TDP, and its 5 nm process from TSMC represents a smaller manufacturing node than Intel's 10 nm process. It also offers more PCIe lanes (24 versus 16) and a smaller die size (71 mm² versus 257 mm²), which typically correlates with lower manufacturing cost per wafer, though cost data is not recorded here.

The Intel Core i9-14901KE wins on raw specification counts. It has 2 more cores and 4 more threads, a base clock 0.50 GHz higher, a boost clock 1.50 GHz higher, a 20 MB larger shared L3 cache, and larger per-core L1 and L2 caches. It supports both DDR4 and DDR5 memory, which provides broader memory compatibility than the AMD part's DDR5-only support. Its UHD Graphics 770 integrated GPU is present, as is the AMD Radeon Graphics on the other side, so neither has a monopoly on integrated graphics.

For use-case guidance, the data indicates the AMD Ryzen 5 7400 suits scenarios where measured performance, lower power draw, and a newer platform (AM5) are the priorities. The Intel Core i9-14901KE suits scenarios where higher core counts, higher clock speeds, and larger cache capacity are required, accepting a higher TDP and an older release date. However, the absence of benchmark results for the Intel part means its actual performance remains unverified in the database, so any selection favoring it must rely on specification analysis rather than measured outcomes.
