AMD Ryzen 5 40 vs Intel Core i9-14901KE Comparison

The Verdict

The database record for this comparison is unusually one-sided. The AMD Ryzen 5 40 has a complete set of benchmark results, while the Intel Core i9-14901KE has no recorded benchmark scores, no average score, and no rival data. As a result, the quantitative analysis can only describe the AMD processor's measured performance. The Intel part can be assessed only through its architectural and specification profile.

The AMD Ryzen 5 40 is a 4-core, 8-thread Zen 2 mobile processor built on TSMC's 6 nm process. Its benchmark data places it at the 70th percentile of all CPUs in the database, with an average benchmark score of 15882. Its nearest rivals in the database, the AMD EPYC 75F3 at 15859, the Intel Core Ultra 5 134U at 15910, the AMD EPYC 9354P at 15826, and the AMD EPYC 9334 at 15940, are all within a 0.4% margin of its average score. This indicates that despite its low core count and mobile positioning, the Ryzen 5 40 delivers average performance comparable to server-class EPYC parts in the database's aggregate metric.

The Intel Core i9-14901KE is an 8-core, 16-thread Raptor Lake desktop processor on Intel's 10 nm process. It holds a 50th percentile rating but has no benchmark scores recorded. The intended user profile is clear from the architecture, but measured data is absent.

Strictly from the data, the Ryzen 5 40 is the only part with verifiable performance numbers. Any user requiring a processor with confirmed benchmark results would select the Ryzen 5 40 based on available measurements. The i9-14901KE offers a larger core count, higher clocks, more cache, and desktop-oriented features, but the database currently contains no scores to validate its performance.

Architecture Differences

The two processors come from entirely different architectural lineages. The AMD Ryzen 5 40 is built on the Zen 2 architecture with the Mendocino codename, part of the Ryzen 5 generation. The Intel Core i9-14901KE uses the Raptor Lake architecture with the Raptor Lake-R codename, belonging to the Core 14th Gen series.

The manufacturing process differs substantially. AMD uses TSMC's 6 nm node, while Intel uses its own 10 nm process. The die sizes reflect this gap: the Ryzen 5 40 has a die size of 100 mm², while the i9-14901KE has a die size of 257 mm². Neither part has transistor counts recorded in the database.

Cache topology differs in both capacity and organization. The Ryzen 5 40 has 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The i9-14901KE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Intel part has nine times the L3 capacity of the AMD part.

Platform support diverges sharply. The Ryzen 5 40 uses AMD Socket FT6, a mobile socket, and its PCIe support is Gen 3 with 4 lanes from the CPU. The i9-14901KE uses Intel Socket 1700, a desktop socket, with PCIe Gen 5 and 16 lanes from the CPU. The mobile versus desktop split is confirmed by the market segment fields: Mobile for AMD, Desktop for Intel.

The integrated graphics also differ. AMD pairs the Ryzen 5 40 with a Radeon 610M GPU. Intel equips the i9-14901KE with UHD Graphics 770. The AMD part is not multiplier-unlocked, while the Intel part is multiplier-unlocked.

The release dates in the database are separated by over a year. The Intel part was released on 2024-06-30, and the AMD part on 2025-09-30. Both remain in active production status.

Specification Differences

The core and thread counts differ by a factor of two. The Ryzen 5 40 has 4 cores and 8 threads. The i9-14901KE has 8 cores and 16 threads.

Clock speeds favor Intel. The Ryzen 5 40 runs at a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The i9-14901KE runs at a base clock of 3.80 GHz and a boost clock of 5.80 GHz. The Intel part's base clock is 1.00 GHz higher, and its boost clock is 1.50 GHz higher.

Power targets are not directly comparable given the different market segments. The Ryzen 5 40 has a TDP of 15, reflecting its mobile design. The i9-14901KE has a TDP of 125, reflecting its desktop design.

Memory support differs. The Ryzen 5 40 supports LPDDR5 memory over a dual-channel bus with a recorded memory bandwidth of 88.0 GB/s. The i9-14901KE supports both DDR4 and DDR5 over a dual-channel bus, but no memory bandwidth figure is recorded in the database.

ECC memory support is exclusive to the Intel part. The i9-14901KE lists ECC memory as true, while the Ryzen 5 40 lists it as false.

The part numbers and unlock status also differ. The Intel part has a recorded part number of Q49DSRNJC and a multiplier-unlocked status of true. The AMD part has an unknown part number and is not multiplier-unlocked.

The Ryzen 5 40 has no launch MSRP recorded. The i9-14901KE also has no launch MSRP recorded.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty. No direct comparison scores exist between the AMD Ryzen 5 40 and the Intel Core i9-14901KE. The win counts for both sides are recorded as zero.

The only benchmark data available comes from the Ryzen 5 40's individual test suite. In Cinebench R15, the Ryzen 5 40 scores 790 in multicore and 165.5 in singlecore. In Cinebench R23, it scores 4841 in multicore and 1150 in singlecore. These are modest numbers consistent with a low-power mobile processor.

The Passmark suite shows a wider spread. The Ryzen 5 40 scores 141533 in data compression, 6646 in data encryption, 6437 in extended instructions, 20 in find prime numbers, 15194 in floating point math, 31598 in integer math, 9341 in multithread, 432 in physics, 15124 in random string sorting, and 2477 in both single thread and singlethread tests.

The average benchmark score of 15882 and the 70th percentile ranking give context to these individual results. The Ryzen 5 40 sits above half the CPUs in the database despite its 4-core mobile configuration. Its nearest rivals, the EPYC 75F3, EPYC 9354P, EPYC 9334, and Core Ultra 5 134U, all fall within a 0.4% band of its average score, which suggests the aggregate metric is tightly clustered around this performance level.

Since the i9-14901KE has no recorded scores, there are no exact numbers to compare against the Ryzen 5 40's results. Any head-to-head statement beyond the architectural specification differences would require data the database does not currently contain.

Where Each One Wins

Based strictly on recorded data, the AMD Ryzen 5 40 wins in every measurable category, because it is the only processor with benchmark results. It has a 70th percentile ranking versus the Intel part's 50th percentile, an average benchmark score of 15882 versus 0, and a complete suite of individual test scores. The Intel Core i9-14901KE has no wins recorded in the database.

The specification sheet, however, shows areas where the Intel part holds advantages that are not yet backed by benchmark data. The i9-14901KE has double the cores and threads, higher base and boost clocks, a much larger L3 cache, PCIe Gen 5 support with 16 lanes, ECC memory support, and a desktop socket with a larger die. These features would typically favor desktop workloads, but the database contains no measured results to confirm their impact.

The Ryzen 5 40's strengths are its efficiency-oriented design and its verified performance. Its 15 TDP, 6 nm process, 100 mm² die, and LPDDR5 memory support fit a mobile platform. Its benchmark scores place it at the 70th percentile of all CPUs, and its nearest rivals are all server-class EPYC processors, which indicates its aggregate performance is competitive with much larger parts in the database's metric.

The use-case split is therefore determined by data availability. For any workload requiring verified benchmark numbers, the Ryzen 5 40 is the only choice. For workloads where core count, cache size, memory flexibility, and desktop platform features matter, the i9-14901KE offers a stronger theoretical profile, but its absence from the benchmark database leaves its performance unconfirmed.
