Architecture Differences

The AMD Ryzen 5 8400F is built on the Zen 4 architecture with the Phoenix codename, fabricated on TSMC’s 4 nm process. It contains 25,000 million transistors on a 178 mm² die. The Intel Core i7-13620H uses the Raptor Lake architecture (Raptor Lake-H codename) on Intel’s 10 nm process. The Intel chip’s transistor count and die size are not listed in the data.

Cache configurations differ substantially. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. Intel’s larger L3 cache (24 MB vs 16 MB) gives it more on-die capacity for frequently accessed data.

Memory support diverges as well. The AMD Ryzen 5 8400F supports DDR5 only, with dual-channel memory and a listed bandwidth of 83.2 GB/s. The Intel Core i7-13620H supports both DDR4 and DDR5, also dual-channel, but its memory bandwidth is not provided in the data. This makes the AMD chip more limited in memory flexibility but explicit in its bandwidth rating.

Integrated graphics differentiate the two heavily. The Intel chip includes UHD Graphics 770, while the AMD part has no integrated graphics (N/A). This means the Ryzen 5 8400F requires a discrete GPU for any display output, whereas the Core i7-13620H can operate without a dedicated graphics card. The Intel chip’s market segment is Mobile, using the Intel BGA 1744 socket, while the AMD chip is a Desktop processor on AMD Socket AM5.

The AMD chip has an unlocked multiplier, enabling overclocking, while the Intel part is locked. Process nodes also differ: 4 nm for AMD versus 10 nm for Intel. The AMD chip’s boost clock is 4.70 GHz, lower than Intel’s 4.90 GHz, but its base clock is much higher at 4.20 GHz versus 2.40 GHz. TDP ratings show AMD at 65 W and Intel at 45 W.

The Verdict

The data points to a clear split by workload type. The AMD Ryzen 5 8400F dominates in modern multi-core rendering and single-core Cinebench tests, while the Intel Core i7-13620H excels in older 3DMark multi-threaded workloads and certain PassMark math/physics tests.

For users prioritizing Cinebench R23 multi-core performance, the Ryzen 5 8400F is the obvious choice—its 37.4% lead over the Intel chip is decisive. The AMD part also wins Cinebench R20 multi-core by 5.4% and R15 single-core by 12.5%. Users running rendering or CPU-bound creative workloads where Cinebench scores correlate strongly with real-world performance should favor the AMD chip.

For users focused on 3DMark results, the Intel Core i7-13620H wins every 3DMark test in the head-to-head, including 16-thread (7056 vs 6091, 13.7% ahead) and max-thread (7178 vs 6165, 14.1% ahead). The Intel chip also leads in PassMark physics (1671 vs 1332, 20.3% ahead) and floating-point math (59762 vs 46217, 22.7% ahead). These wins suggest Intel’s advantage in certain physics simulations and floating-point-heavy tasks.

The overall benchmark score difference is negligible—0.4% in AMD’s favor. The Ryzen 5 8400F wins 12 of 23 head-to-head tests, while the Intel wins 11. This is a near-even split. The deciding factor is the specific application mix. If the workload resembles Cinebench R23, the AMD chip wins decisively. If it resembles 3DMark or physics-heavy PassMark tests, the Intel chip wins. The Intel processor’s integrated graphics also make it viable for systems without a discrete GPU, while the AMD chip requires one.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 5 8400F comes in Cinebench R23 multi-core, where it scores 20851 against Intel’s 15176—a 37.4% advantage. The single-core R23 test is even more lopsided in AMD’s favor: 2943 versus 1833, a 60.6% lead. These are the two biggest deltas in the entire comparison. The AMD chip also wins Cinebench R20 multi-core (8757 vs 8305, 5.4% ahead) and R20 single-core (1236 vs 1172, 5.5% ahead), plus R15 single-core (296 vs 263, 12.5% ahead).

In PassMark tests, the AMD chip wins data encryption (16646 vs 15568, 6.9% ahead), extended instructions (22175 vs 17513, 26.6% ahead), random string sorting (34604 vs 29395, 17.7% ahead), data compression (288158 vs 281335, 2.4% ahead), and both single-thread entries (3685 vs 3589, 2.7% ahead). The PassMark multithread test is nearly tied, with AMD ahead by just 0.8% (24389 vs 24192).

The Intel Core i7-13620H’s biggest win is PassMark floating-point math, scoring 59762 against AMD’s 46217—a 22.7% lead. The Intel chip also wins PassMark physics by 20.3% (1671 vs 1332) and PassMark find prime numbers by 10.1% (99 vs 89). In 3DMark, Intel wins all six tests: 16-thread by 13.7% (7056 vs 6091), max-thread by 14.1% (7178 vs 6165), single-thread by 5.7% (1008 vs 951), 2-thread by 4.5% (1963 vs 1874), 8-thread by 3.1% (5443 vs 5275), and 4-thread by 1.6% (3621 vs 3563). Intel also wins Cinebench R15 multi-core by 7.9% (2281 vs 2101) and PassMark integer math by 8.6% (80948 vs 74021).

Where Each One Wins

The AMD Ryzen 5 8400F wins decisively in Cinebench R23 workloads, which are often used to estimate heavy multi-threaded rendering performance. Its 37.4% multi-core and 60.6% single-core leads in R23 are the clearest signals in the data. The AMD chip also wins every PassMark test related to data manipulation: compression, encryption, extended instructions, random string sorting, and single-thread performance. Users running long multi-core renders, data compression pipelines, or encryption-heavy tasks should expect the AMD chip to finish faster.

The Intel Core i7-13620H wins all 3DMark tests, including the 16-thread and max-thread variants that stress broader parallel workloads. Its 13.7% and 14.1% leads in those tests suggest an edge in gaming-related multi-threaded scenarios, though the gap narrows at 4-thread (1.6%). The Intel chip also dominates PassMark floating-point math (22.7% ahead) and physics (20.3% ahead), indicating strength in scientific computing and physics simulations. Users with workloads that resemble 3DMark or physics engines should lean toward the Intel processor.

The overall split is nearly even—12 wins for AMD, 11 for Intel—but the magnitude of AMD’s wins is larger in the most demanding rendering tests. The Intel chip’s wins are spread across more tests but include several narrow margins (4-thread 3DMark at 1.6%, multithread PassMark at 0.8%). The AMD chip’s wins include two blowouts (R23 multi-core and single-core) and a 26.6% lead in extended instructions. For pure CPU compute, the data favors AMD in rendering and data processing; for physics and floating-point math, Intel holds clear advantages.
