AMD Ryzen 3 3100U vs Intel Core i5-14500HX Comparison

The AMD Ryzen 3 3100U and Intel Core i5-14500HX occupy opposite ends of the mobile processor spectrum. The recorded data shows the Intel part winning every single head-to-head benchmark in the database, with an average benchmark score of 35094 compared to 6247 for the AMD chip. The Intel Core i5-14500HX sits in the 84th percentile of all CPUs, while the Ryzen 3 3100U lands in the 62nd percentile. These are not competing products in any practical sense; they serve entirely different market segments within the mobile space.

Where Each One Wins

The Intel Core i5-14500HX wins all 11 recorded head-to-head benchmarks. The AMD Ryzen 3 3100U has zero benchmark wins in the database. The largest margins come in floating point math, where the Intel part scores 69442 against 5854 for AMD, a delta of -91.6%. Integer math shows a similar gap: 95584 versus 8873, a -90.7% difference. These results indicate the Intel processor is decisively ahead in compute-heavy workloads such as scientific calculations, financial modeling, and any task that relies heavily on arithmetic throughput.

The single-thread results tell a somewhat less extreme but still one-sided story. The Intel Core i5-14500HX records 3629 in the passmark single-thread test, while the AMD Ryzen 3 3100U manages 1592. That is a -56.1% delta, meaning Intel still leads by more than double in lightly threaded applications. For everyday responsiveness, browser rendering, or legacy single-threaded software, the Intel part holds a commanding advantage.

The AMD Ryzen 3 3100U does not win any category, but its profile is that of a low-power, dual-core part. Its 15 watt TDP compared to the Intel's 55 watt TDP indicates it is designed for basic productivity and power-sensitive scenarios. The data shows the AMD chip still delivers a functional baseline: a passmark multithread score of 3348, which is usable for light office work, though the Intel part's 28508 in the same test makes the comparison moot. The use-case split is not about workload types; it is about power envelopes and physical design constraints.

Architecture Differences

The two processors come from completely different design lineages. The AMD Ryzen 3 3100U uses the Picasso architecture, which is based on the Zen+ microarchitecture, and is manufactured on a 12 nm process at GlobalFoundries. The Intel Core i5-14500HX uses the Raptor Lake architecture, specifically the Raptor Lake-HX refresh, built on a 10 nm process at Intel. The AMD chip integrates 4,940 million transistors on a 210 mm² die. The Intel part has no transistor count listed in the database, but its die size is 257 mm².

Core configurations diverge sharply. The AMD Ryzen 3 3100U has 2 cores and 2 threads, meaning no simultaneous multithreading. The Intel Core i5-14500HX has 14 cores and 20 threads, which reflects a hybrid design with performance and efficiency cores. The Intel part's base clock is 2.60 GHz with a boost of 4.90 GHz, while the AMD chip runs at 1.90 GHz base and 3.20 GHz boost. The cache hierarchy also differs: AMD allocates 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3.

Memory support separates the pair. The AMD Ryzen 3 3100U supports only DDR4 in a dual-channel configuration, with a memory bandwidth of 38.4 GB/s. The Intel Core i5-14500HX supports both DDR4 and DDR5, also dual-channel, with no bandwidth figure recorded. ECC memory is not supported by the AMD chip but is supported by the Intel processor. PCIe generations differ as well: the AMD part uses Gen 3, while the Intel part uses Gen 5 with 16 lanes for the CPU. Integrated graphics are the AMD Radeon Vega 8 versus the Intel UHD Graphics 770. The Intel processor has an unlocked multiplier; the AMD part does not.

Head-to-Head Benchmarks

The database records 11 head-to-head benchmark comparisons, and the Intel Core i5-14500HX wins every one. The smallest margin is in the passmark single-thread and passmark singlethread tests, both showing the same result: Intel at 3629 versus AMD at 1592, a -56.1% delta. This is still a decisive lead, but it is the closest the AMD chip comes to competitive parity.

It also shows Geekbench scores of 10171 multicore and 2129 singlecore. These figures further substantiate the Intel part's dominant position, although no equivalent Cinebench or Geekbench scores are recorded for the AMD Ryzen 3 3100U.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-14500HX outperforms the AMD Ryzen 3 3100U in every measured test. The Intel part's 35094 average benchmark score places it in the 84th percentile of all CPUs, while the AMD chip's 6247 average lands in the 62nd percentile. The nearest rivals to the Intel part are high-end desktop and mobile chips like the Intel Core i9-12900HX and Intel Core i7-12700K, confirming its performance class. The AMD Ryzen 3 3100U's nearest rivals include the AMD Ryzen Threadripper 1950X and the AMD EPYC 7272, which are entirely different product categories, indicating the AMD part's score aligns with a much lower performance tier.

The Intel Core i5-14500HX is built for heavy multi-threaded workloads, with 14 cores, 20 threads, 24 MB of L3 cache, and a 55 watt TDP. It supports DDR5 memory, ECC memory, and PCIe Gen 5, making it a modern high-performance mobile processor. The AMD Ryzen 3 3100U is a 15 watt dual-core part with 4 MB of L3 cache, DDR4 support, and PCIe Gen 3, suited for low-power basic computing. The data shows no scenario where the AMD chip wins, so the selection between the two is determined entirely by power budget and performance requirements. Systems requiring substantial compute throughput should use the Intel part; systems prioritizing minimal power draw with light workloads would use the AMD part, but with the clear understanding that its performance is far lower.
