AMD Ryzen 7 9850X3D vs Intel Core i5-14400F Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 7 9850X3D, which secures 14 of the 15 compared benchmark wins. The single Intel victory is substantial, but it is isolated to one specific workload type. In the Cinebench R23 single-core test, the Intel Core i5-14400F scores 3055 against the AMD part's 2228, a delta of 27.1% in Intel's favor. This is the only metric where the Intel chip leads, and the margin indicates a clear advantage in lightly threaded legacy rendering tasks.

Outside of that single test, the AMD Ryzen 7 9850X3D dominates across both multi-core and single-threaded workloads. In Cinebench R15, the AMD part scores 3551 versus 2181 for the Intel chip, a 62.8% advantage. The R23 multi-core test tells a closer story, with the AMD processor scoring 22807 against 21645, a 5.4% lead. This narrower margin suggests that in heavily optimized modern multi-threaded rendering, the Intel part's extra cores narrow the gap considerably, though the AMD chip still comes out ahead.

The PassMark suite reveals where the AMD processor's architecture pulls far ahead. In the find prime numbers test, the AMD Ryzen 7 9850X3D scores 435 against the Intel Core i5-14400F's 86, a massive 405.8% delta. This result is the largest performance gap recorded in the head-to-head data. Extended instructions show a 97% advantage for AMD, with scores of 39272 versus 19937. Integer math delivers a 51% lead, with the AMD chip scoring 123140 against 81524, while floating point math shows a 33.7% advantage, 81998 versus 61319.

Memory and data handling workloads also favor the AMD processor. Data compression scores 474501 versus 315521, a 50.4% delta. Data encryption shows a 34.9% lead, 22856 against 16949. Random string sorting completes with a 52.3% advantage, 49764 versus 32680. The PassMark multithread score puts the AMD part at 41318 against 25470, a 62.2% lead, while the physics test shows a 173.9% delta, 4171 versus 1523. The PassMark single-thread score also favors AMD, 4704 against 3701, a 27.1% margin that mirrors the Cinebench R15 single-core result of 343 versus 307, an 11.7% advantage.

Architecture Differences

The two processors represent fundamentally different design approaches. The AMD Ryzen 7 9850X3D uses the Zen 5 architecture on the Granite Ridge codename, built on a 4 nm process at TSMC. The Intel Core i5-14400F uses the Raptor Lake architecture with the Raptor Lake-R codename, built on a 10 nm process at Intel. The process node disparity is significant, with the AMD part using a much smaller manufacturing process.

Core configurations differ substantially. The AMD processor has 8 cores and 16 threads, while the Intel processor has 10 cores and 16 threads. Both parts deliver the same thread count, but the Intel chip achieves this with a hybrid approach across more physical cores. The AMD part's base clock is 4.70 GHz with a boost of 5.60 GHz, while the Intel part runs a base of 2.50 GHz and boosts to 4.70 GHz. This clock speed difference helps explain the AMD part's single-thread performance in most tests, though the Intel part's higher R23 single-core score suggests architectural efficiency plays a role as well.

Cache hierarchies diverge sharply. Both parts share the same 80 KB L1 cache per core, but the L2 cache differs: 1 MB per core on the AMD part versus 1.25 MB per core on the Intel part. The L3 cache is where the AMD processor pulls far ahead, offering 96 MB shared versus 20 MB shared on the Intel chip. This 76 MB difference in last-level cache is a defining characteristic of the AMD part and likely contributes to its strong performance in cache-sensitive workloads.

Memory support also differs. The AMD Ryzen 7 9850X3D supports only DDR5 memory, while the Intel Core i5-14400F supports both DDR4 and DDR5. Both use dual-channel memory buses. The AMD part lists a memory bandwidth of 89.6 GB/s, while the Intel part has no recorded bandwidth figure. Both processors support ECC memory. The platform sockets are incompatible, with the AMD part using AMD Socket AM5 and the Intel part using Intel Socket 1700.

PCIe connectivity differs as well. The AMD processor provides Gen 5 with 24 lanes from the CPU, while the Intel processor provides Gen 5 with 16 lanes from the CPU. The AMD part includes integrated Radeon Graphics, while the Intel part has no integrated graphics, designated as N/A. The AMD multiplier is unlocked, the Intel multiplier is not. Transistor counts and die sizes also differ, with the AMD part at 8,315 million transistors on a 70.6 mm² die, while the Intel part has no recorded transistor count but a 215 mm² die size.

Where Each One Wins

The AMD Ryzen 7 9850X3D wins in nearly every measurable category in the database. Its largest margins appear in prime number calculation, physics simulation, and extended instruction workloads. The 405.8% lead in prime number finding and the 173.9% lead in physics strongly indicate that the AMD architecture excels at integer-heavy, branch-heavy, and computational throughput tasks. The 97% lead in extended instructions suggests the AMD part has a more capable execution pipeline for advanced instruction sets.

The AMD processor also dominates memory bandwidth-sensitive workloads. Data compression, encryption, and random string sorting all show leads above 34%, with compression at 50.4% and sorting at 52.3%. These results align with the 96 MB L3 cache, which allows more data to remain resident on-die. The 62.2% multithread lead and 62.8% R15 multi-core lead confirm that despite having fewer physical cores, the AMD part's higher clocks and larger cache deliver superior aggregate throughput.

The Intel Core i5-14400F has exactly one clear winning scenario: Cinebench R23 single-core. The 27.1% lead in that test stands alone. This result indicates that in a specific single-threaded rendering workload, the Intel architecture's efficiency at lower clocks produces a higher score. However, the same workload in R15 single-core goes to AMD by 11.7%, which complicates any simple narrative about Intel single-thread superiority. The data suggests the Intel part wins a narrow slice of legacy single-threaded rendering while losing the broader single-thread picture.

For system builders, the AMD part's 92nd percentile ranking against all CPUs puts it well above the Intel part's 83rd percentile. The average benchmark score tells the same story: 58386 for the AMD part versus 32279 for the Intel part. The nearest rival data for the AMD part shows it trading positions with high-end Xeon and Core i9 parts, with deltas of 0.1%, -0.2%, 0.5%, and -0.7% against its closest competitors. The Intel part's nearest rivals are a mix of Ryzen 7 mobile and older Core i9 parts, with similarly small deltas of 0.1%, 0.2%, -0.2%, and 0.5%.
