AMD Ryzen 3 3100U vs Intel Core i3-14100F Comparison

The AMD Ryzen 3 3100U is a 15-watt mobile processor built for efficiency, while the Intel Core i3-14100F is a 58-watt desktop part focused on raw performance. The benchmark data shows a complete sweep: the Intel Core i3-14100F wins all 11 recorded head-to-head tests, with the AMD Ryzen 3 3100U trailing by margins between 57.9% and 83.4%. This is not a close contest; it is a generational and architectural chasm that places the two chips in entirely different performance tiers.

Where Each One Wins

The recorded data shows no benchmark wins for the AMD Ryzen 3 3100U. It loses every single head-to-head comparison to the Intel Core i3-14100F, from single-threaded workloads to multi-threaded compression tasks. The closest margin is in the single-thread tests, where the AMD chip trails by 57.9%, and the widest gap is in floating-point math, where it trails by 83.4%.

The Intel Core i3-14100F wins everywhere in the database. Its largest advantages appear in floating-point math, extended instructions, and data compression, where it outperforms the AMD Ryzen 3 3100U by more than 78% in each case. The Intel chip also holds a decisive lead in multi-threaded performance, scoring 15420 in PassMark multithread versus 3348 for the AMD part.

The AMD Ryzen 3 3100U does have a role, but it is not defined by benchmark victories. Its 15-watt TDP, integrated Radeon Vega 8 graphics, and mobile socket (AMD Socket FP5) place it in thin-and-light laptops. The Intel Core i3-14100F, with no integrated graphics and a desktop socket, targets budget desktop builds where a discrete GPU is already planned. The data indicates that the Intel part is the performance pick, while the AMD part is the efficiency-oriented mobile option.

Architecture Differences

The two processors come from different eras and design philosophies. The AMD Ryzen 3 3100U uses the Picasso architecture, a Zen+ derivative built on a 12 nm process at GlobalFoundries. It packs 4,940 million transistors into a 210 mm² die. The Intel Core i3-14100F uses Raptor Lake-R, a 10 nm Intel design with a 163 mm² die. The node advantage goes to Intel, though the transistor count for the Intel part is not recorded in the database.

Core counts differ sharply. The AMD chip provides 2 cores and 2 threads, while the Intel chip provides 4 cores and 8 threads. That 4-core, 8-thread configuration gives the Intel part a massive multi-threading advantage, which shows in the multithread benchmark score of 15420 versus 3348.

Cache layouts also diverge. The AMD Ryzen 3 3100U has 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3. The Intel Core i3-14100F has 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. While the per-core L1 is smaller on Intel, the larger L2 and triple the L3 capacity give it a significant cache advantage.

Memory support is another dividing line. The AMD part supports only DDR4, while the Intel part supports both DDR4 and DDR5. Both use dual-channel memory buses, but the AMD chip records a memory bandwidth of 38.4 GB/s, while the Intel chip has no bandwidth figure recorded. The Intel part also supports ECC memory, which the AMD chip does not.

PCIe capabilities differ as well. The AMD Ryzen 3 3100U uses PCIe Gen 3, while the Intel Core i3-14100F uses PCIe Gen 5 with 16 CPU lanes. Integrated graphics are present on the AMD chip (Radeon Vega 8) and absent on the Intel part, which is labeled N/A.

Head-to-Head Benchmarks

The head-to-head data is one-sided across all 11 tests. The Intel Core i3-14100F wins every comparison, and the margins are consistently large.

The smallest gap is in single-threaded performance. In the PassMark single-thread test, the Intel chip scores 3778 against 1592 for the AMD chip, a 57.9% advantage. This is the closest result in the entire dataset, yet it still represents a massive single-core lead for Intel.

The largest margin appears in floating-point math. The Intel Core i3-14100F scores 35370, while the AMD Ryzen 3 3100U scores 5854, a 83.4% difference. The extended instructions test shows a similar pattern: 11984 for Intel versus 2116 for AMD, a 82.3% gap.

Data compression shows the Intel chip at 176106 versus 38455, a 78.2% lead. Data encryption follows at 8922 versus 1972, a 77.9% gap. Integer math is also lopsided: 45357 versus 8873, an 80.4% difference.

The multithread test confirms the core-count advantage. Intel scores 15420 versus 3348, a 78.3% lead. Physics testing shows 1077 versus 232, a 78.5% gap. Random string sorting shows 17596 versus 4666, a 73.5% difference.

The prime numbers test is the smallest absolute difference. The Intel chip scores 61 versus 18, a 70.5% lead, but the absolute numbers are low for both parts in this specific workload.

The average benchmark score tells the same story. The Intel Core i3-14100F averages 18519, placing it in the 72nd percentile of all CPUs. The AMD Ryzen 3 3100U averages 6247, placing it in the 62nd percentile. The Intel chip's nearest rivals include the Intel Core i5-13420H at 18511 and the AMD Ryzen 3 PRO 8300GE at 18505, both within 0.1% of its score. The AMD chip's nearest rivals are far lower, including the AMD Ryzen Threadripper 1950X at 6231 and the Intel Core i9-10920X at 6347.

The Verdict

The data is unambiguous: the Intel Core i3-14100F is the superior processor in every measured benchmark category. It doubles the core count, nearly doubles the boost clock (4.70 GHz versus 3.20 GHz), and delivers between 57.9% and 83.4% more performance depending on the workload. Its average score of 18519 places it in the 72nd percentile, while the AMD Ryzen 3 3100U sits at 6247 in the 62nd percentile.

The AMD Ryzen 3 3100U should be selected only for its intended mobile role. Its 15-watt TDP, integrated Radeon Vega 8 graphics, and FP5 socket make it suitable for low-power laptops where battery life matters more than throughput. The Intel Core i3-14100F, with a 58-watt TDP and no integrated graphics, is the choice for a desktop build that already includes a discrete GPU and prioritizes compute performance. For any workload captured in the database, the Intel part wins. For any system where power draw and integrated graphics are mandatory, the AMD part remains the only option of the two.
