AMD Ryzen 3 3100U vs Intel Core i9-14900F Comparison

Head-to-Head Benchmarks

The recorded data presents a decisive matchup. In every single head-to-head benchmark tracked in the database, the Intel Core i9-14900F outperforms the AMD Ryzen 3 3100U. The largest margins appear in compute-heavy workloads. In floating point math, the Intel part scores 119,550 against 5,854 for the AMD chip, a delta of -95.1%. Integer math shows a similar story: 177,066 versus 8,873, a -95% difference. These are not close contests; the i9-14900F delivers more than twenty times the throughput in these specific tests.

The gap narrows somewhat in single-threaded performance, but remains substantial. The i9-14900F records 4,506 in the PassMark single-thread test, while the Ryzen 3 3100U manages 1,592, a delta of -64.7%. This indicates that even in lightly threaded scenarios, the Intel processor holds a significant per-core advantage. Data encryption shows the i9-14900F at 34,644 versus 1,972 for the AMD, a -94.3% delta, while extended instructions (a proxy for SIMD and AVX workloads) see the Intel at 31,084 against 2,116, a -93.2% gap.

Multithreaded performance is where the core count difference becomes stark. The i9-14900F posts 46,532 in PassMark's multithread test; the Ryzen 3 3100U scores 3,348, a -92.8% delta. Random string sorting, a memory-latency sensitive task, shows 63,728 for Intel versus 4,666 for AMD, -92.7%. Physics simulation follows suit: 2,899 for Intel versus 232 for AMD, -92%. Prime number finding, another integer-heavy task, sees 209 versus 18, a -91.4% gap. Data compression mirrors this: 564,207 for the i9-14900F against 38,455 for the Ryzen, -93.2%.

The average benchmark score in the database places the i9-14900F at 60,008, while the Ryzen 3 3100U averages 6,247. The Intel processor sits in the 92nd percentile of all CPUs, whereas the AMD chip is in the 62nd percentile. The nearest rivals for the i9-14900F include the AMD Ryzen 9 7945HX (average score 60,099, delta -0.2%) and the Ryzen 7 8745HX (60,104, delta -0.2%), showing it trades blows with those parts. The Ryzen 3 3100U's nearest rivals are far lower in the performance hierarchy, such as the AMD Ryzen Threadripper 1950X (6,231, delta 0.3%) and the Intel Core i9-10920X (6,347, delta -1.6%), indicating its average score is in a completely different performance class.

The Verdict

From the recorded data, the choice is unambiguous for anyone needing maximum compute performance. The Intel Core i9-14900F wins every single benchmark category in the head-to-head comparison. Its 24 cores and 32 threads provide a massive parallel workload advantage, reflected in the multithread score of 46,532 versus 3,348. The single-thread score of 4,506 versus 1,592 also shows that the Intel architecture leads even when only one or two threads are active.

The AMD Ryzen 3 3100U is a mobile processor with 2 cores and 2 threads, designed for low-power environments (15 W TDP versus 65 W). Its 62nd percentile ranking places it near desktop parts like the Intel Core i9-7940X (delta 1.6%) in average score, but that only underscores how far behind the i9-14900F it sits. For tasks like data encryption, floating point math, or physics simulation, the i9-14900F delivers between 12.5 and 20.4 times the performance. The data shows no scenario where the Ryzen 3 3100U wins. The i9-14900F's nearest rivals are all high-end desktop or mobile HX parts, while the Ryzen 3 3100U competes with older HEDT chips from 2017-2019. The verdict is straightforward: the Intel part is in a different performance tier entirely.

Architecture Differences

The two processors belong to different architectural generations and design philosophies. The AMD Ryzen 3 3100U uses the Picasso codename, based on the Zen+ microarchitecture, fabricated on a 12 nm process at GlobalFoundries. It integrates 4,940 million transistors on a 210 mm² die. The Intel Core i9-14900F uses the Raptor Lake-R codename, based on the Raptor Lake architecture (14th generation Core i9), built on Intel's 10 nm process with a 257 mm² die size.

The cache hierarchies diverge significantly. The AMD chip provides 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel part offers 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. This nine-fold difference in L3 capacity directly impacts workloads that benefit from large shared caches, such as data compression and virtualization.

The i9-14900F supports both DDR4 and DDR5 memory, while the Ryzen 3 3100U is limited to DDR4. The Intel part also supports ECC memory, which the AMD chip does not. PCIe capabilities differ: the i9-14900F uses Gen 5 with 16 CPU lanes, whereas the Ryzen 3 3100U is limited to Gen 3. The integrated graphics situation is reversed: the AMD chip includes Radeon Vega 8 graphics, while the Intel F-series part has no integrated graphics (N/A).

The AMD chip is a mobile part designed for Socket FP5, while the Intel chip targets desktop Socket 1700. The i9-14900F has a boost clock of 5.80 GHz versus 3.20 GHz for the Ryzen. The base clocks are closer (2.00 GHz versus 1.90 GHz), but the boost behavior shows the Intel part's superior clock scaling. Neither processor has an unlocked multiplier.
