AMD Ryzen 5 8400F vs Intel Core i5-14501E Comparison

Head-to-Head Benchmarks

The AMD Ryzen 5 8400F and Intel Core i5-14501E present an unusual comparison in the database because the Intel part has no recorded benchmark scores. The head-to-head benchmark table is empty, and the Intel Core i5-14501E carries an average benchmark score of zero with no nearest rivals listed. This means a direct score-by-score comparison is impossible from the recorded data. However, the AMD Ryzen 5 8400F has a full benchmark suite that can be interpreted on its own terms.

The AMD Ryzen 5 8400F posts an average benchmark score of 25005, placing it in the 77th percentile of all CPUs in the database. Its closest rival is the AMD Ryzen 5 7500F with an average score of 24964, a delta of 0.2 percent, meaning the 8400F is marginally ahead. The Intel Core i7-11850H sits at 24935, a 0.3 percent delta, and the Intel Core i7-13620H follows at 24911, a 0.4 percent delta. The only rival it trails is the AMD EPYC 9474F at 25103, a negative delta of 0.4 percent. These margins are razor-thin, indicating that the 8400F performs within a tight cluster of processors rather than dominating any of them.

Looking at the AMD part's individual results, the Cinebench R23 multicore score of 20851 shows strong sustained multi-threaded throughput for a 6-core, 12-thread chip. The single-core score of 2943 in the same test is solid. In 3DMark, the max-thread score of 6165 edges out the 8-thread score of 5275, while the 16-thread score of 6091 is slightly lower than max-thread, suggesting the extra threads from SMT provide diminishing returns beyond 8 threads. The single-thread score of 951 is notably lower than the 2-thread score of 1874, which is roughly double, indicating near-linear scaling at low thread counts.

PassMark results tell a similar story. The multithread score of 24389 is respectable, while single-thread sits at 3685. Integer math scores 74021, floating-point math scores 46217, and extended instructions score 22175. Data compression yields 288158, data encryption 16646, and random string sorting 34604. Physics simulation scores 1332, and finding prime numbers scores 89. These are the recorded data points; the Intel part has none, so the head-to-head section must conclude that the database contains no comparative benchmark evidence for the Intel Core i5-14501E.

Architecture Differences

The two processors diverge fundamentally in architecture, manufacturing, and platform support. The AMD Ryzen 5 8400F uses the Zen 4 architecture with the Phoenix codename, built on a 4 nm process at TSMC. The Intel Core i5-14501E uses Raptor Lake architecture with the Raptor Lake-R codename, built on a 10 nm process at Intel. The process node difference is significant: 4 nm versus 10 nm, which typically implies different transistor density and power characteristics, though the database does not provide transistor counts for the Intel part. The AMD die size is 178 mm² with 25,000 million transistors, while the Intel die size is 215 mm² with no transistor count recorded.

Both chips have 6 cores and 12 threads, but cache configurations differ. The AMD part has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Intel part has 80 KB L1 per core, 1.25 MB L2 per core, and 24 MB shared L3. The Intel chip carries more cache at every level, which could favor certain workloads, but no benchmark data exists to confirm this.

Clock speeds also differ. The AMD base clock is 4.20 GHz with a boost of 4.70 GHz. The Intel base clock is 3.30 GHz with a boost of 5.20 GHz. The Intel part has a higher boost clock by 0.50 GHz, while the AMD part has a higher base clock by 0.90 GHz. Both have a 65 W TDP. The AMD multiplier is unlocked, allowing overclocking, while the Intel multiplier is locked.

Memory support diverges: the AMD part supports DDR5 only, dual-channel, with a recorded memory bandwidth of 83.2 GB/s. The Intel part supports both DDR4 and DDR5, dual-channel, with no bandwidth figure recorded. ECC memory is supported on the Intel part but not on the AMD part.

PCIe generations differ as well. The AMD CPU provides Gen 4 with 20 lanes, while the Intel CPU provides Gen 5 with 16 lanes. The Intel part also includes integrated graphics (UHD Graphics 770), while the AMD part has no integrated graphics (N/A).

Sockets are incompatible: AMD uses Socket AM5, Intel uses Socket 1700. The AMD part launched on 2024-03-31 with a launch MSRP of $170, while the Intel part launched on 2024-06-30 with no recorded launch MSRP. Both are active production parts.

Where Each One Wins

The AMD Ryzen 5 8400F wins in areas where the recorded data supports it. It has a higher base clock (4.20 GHz versus 3.30 GHz), which can benefit sustained workloads that do not rely on boost behavior. It has more PCIe lanes (20 versus 16), though its PCIe generation is older (Gen 4 versus Gen 5). The AMD part has an unlocked multiplier, enabling overclocking for users who want to push beyond stock settings. It also has a significantly smaller die size (178 mm² versus 215 mm²) and a smaller process node (4 nm versus 10 nm), which may imply better power efficiency, though no power measurements are recorded. The AMD part launched with a $170 MSRP, though pricing comparisons are not part of this analysis.

The Intel Core i5-14501E wins on paper in several specification categories. It has a higher boost clock (5.20 GHz versus 4.70 GHz), which can be advantageous for lightly threaded workloads that reach boost frequencies. It has more cache at all levels: 80 KB L1 per core versus 64 KB, 1.25 MB L2 per core versus 1 MB, and 24 MB L3 versus 16 MB. It supports both DDR4 and DDR5 memory, giving platform flexibility, whereas the AMD part is DDR5-only. The Intel part supports ECC memory, which the AMD part does not. It includes integrated graphics (UHD Graphics 770), meaning a system can operate without a discrete GPU for basic display output. It also supports PCIe Gen 5, albeit with fewer lanes, which could be relevant for future high-bandwidth devices.

The Intel part has a larger die size and older process node, but the database does not record benchmark scores for it, so performance wins cannot be quantified. The AMD part has a full benchmark suite and a 77th percentile ranking, but the Intel part's 50th percentile placement with zero average score is not a performance measurement; it reflects the absence of data.

The Verdict

The database presents an asymmetric picture. The AMD Ryzen 5 8400F has extensive benchmark coverage, placing in the 77th percentile with an average score of 25005, and it sits within 0.4 percent of four closely matched rivals. The Intel Core i5-14501E has no recorded benchmark scores, an average score of zero, and no nearest rivals, making any performance-based selection impossible from the data.

From a specification standpoint, the Intel part offers more cache, a higher boost clock, ECC support, integrated graphics, and dual memory type compatibility. The AMD part offers a higher base clock, an unlocked multiplier, more PCIe lanes, a smaller process node, and a smaller die. The AMD part also has a recorded launch MSRP of $170, while the Intel part has no recorded MSRP.

For a user prioritizing measured performance data, the AMD Ryzen 5 8400F is the only choice with evidence in the database. For a user prioritizing features such as ECC memory, integrated graphics, or DDR4 compatibility, the Intel Core i5-14501E has specification advantages, but those advantages are not backed by any benchmark results. The verdict, strictly from the data, is that the AMD part is the better-documented processor with a proven performance profile, while the Intel part remains unverified in the database.
