The physics test follows suit, with Intel scoring 958 and AMD scoring 232, a -75.8 percent difference. Random string sorting, a memory-heavy workload, shows the Intel part at 17397 versus 4666, a -73.2 percent gap.

Single-thread performance, critical for everyday responsiveness and lightly threaded applications, shows the narrowest relative gap but still a significant one. The Core i3-14100 scores 3759, while the Ryzen 3 3100U scores 1592, a -57.6 percent delta. Data encryption and prime number finding complete the sweep, with the Intel processor ahead by -77.7 percent and -67.3 percent respectively.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 3100U is built on a 12 nm process at GlobalFoundries, using the Picasso architecture based on Zen+. It features 2 cores and 2 threads, with a base clock of 1.90 GHz and a boost clock of 3.20 GHz. This is a mobile-focused part, evidenced by its 15 watt TDP and AMD Socket FP5.

The Intel Core i3-14100 uses a 10 nm process from Intel, codenamed Raptor Lake-R and based on the Raptor Lake architecture. It provides 4 cores and 8 threads, with a base clock of 3.50 GHz and a boost clock of 4.70 GHz. Its 60 watt TDP and Intel Socket 1700 confirm its desktop positioning.

Cache configurations differ notably. The AMD part carries 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel processor has 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The larger L3 pool on the Intel chip is a significant advantage for workloads that repeatedly access a working set of data.

Transistor counts and die sizes also differ. The AMD Picasso die contains 4,940 million transistors on a 210 mm² die. The Intel Raptor Lake-R die measures 163 mm², though its transistor count is not recorded. Memory support shows clear generational separation: the AMD part supports DDR4 only, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses. The AMD lists a memory bandwidth of 38.4 GB/s, while the Intel figure is not recorded.

PCIe capabilities differ as well. The Ryzen 3 3100U uses PCIe Gen 3, while the Core i3-14100 supports PCIe Gen 5 with 16 lanes from the CPU. The Intel processor also supports ECC memory, a feature not available on the AMD part. Integrated graphics differ, with the AMD using Radeon Vega 8 and the Intel using UHD Graphics 730. The AMD chip has a locked multiplier, as does the Intel part.

Where Each One Wins

The recorded data shows no benchmark wins for the AMD Ryzen 3 3100U. Its nearest rivals in the database include the AMD Ryzen Threadripper 1950X, which scores 6231 and is 0.3 percent ahead, and the AMD EPYC 7272 at 6186, which is 1 percent ahead. The Intel Core i9-10920X sits 1.6 percent behind the AMD at 6347, and the Intel Core i9-7940X is 1.6 percent behind at 6147. This grouping places the Ryzen 3 3100U in the company of much older high-core-count parts, though it cannot match their aggregate throughput.

The Intel Core i3-14100, by contrast, sits among a tight cluster of modern low-end and midrange desktop chips. Its nearest rivals are the Intel Core 3 305 at 18302, which is 0.1 percent behind, the Intel Core 5 330 at 18345, which is 0.1 percent ahead, and the Intel Core 7 360 at 18374, which is 0.3 percent ahead. The Intel Core i3-13100 is 0.3 percent ahead at 18380. This shows the Core i3-14100 is benchmarked directly against other current-generation Intel parts, with the differences between them being minimal.

The use-case split is therefore clear from the data. The Core i3-14100 is the processor for any workload where performance matters, from multithreaded compilation to single-threaded application response. Its 4-core, 8-thread configuration with a 4.70 GHz boost clock gives it a commanding lead in every measured category. The Ryzen 3 3100U, with its 2-core, 2-thread design and 3.20 GHz boost clock, is positioned for low-power mobile systems where the 15 watt TDP is the defining constraint.

The Verdict

The benchmark data delivers an unambiguous result. The Intel Core i3-14100 wins every recorded head-to-head test against the AMD Ryzen 3 3100U, with deltas ranging from -57.6 percent in single-thread performance to -83.4 percent in floating point math. The Intel part also holds a higher percentile ranking, 72nd versus 62nd, and a substantially higher average benchmark score of 18318 versus 6247.

The Ryzen 3 3100U should be selected only for systems where its 15 watt TDP and mobile socket are mandatory. Its 2-core, 2-thread configuration and 12 nm process place it in a different performance class entirely. The Intel Core i3-14100, with 4 cores, 8 threads, a 4.70 GHz boost clock, and 12 MB of L3 cache, is the choice for any workload where processing power is the priority. The data shows no scenario where the AMD part is competitive on performance, leaving its low power draw as its only distinguishing advantage.
