Architecture Differences

The two processors come from fundamentally different design eras. The AMD Ryzen 3 3100U is a Picasso part based on the Zen+ microarchitecture, fabricated on a 12 nm process at GlobalFoundries. The Intel Core i5-14450HX is a Raptor Lake-HX Refresh part using Intel's 10 nm process. The AMD chip integrates 4,940 million transistors on a 210 mm² die, while the Intel die measures 257 mm².

Core configuration separates these two sharply. The Ryzen 3 3100U offers 2 cores and 2 threads with no simultaneous multithreading. The Core i5-14450HX provides 10 cores and 16 threads, indicating a hybrid arrangement with performance and efficiency cores. Clock speeds also diverge: the AMD part runs at 1.90 GHz base and 3.20 GHz boost, while Intel operates at 2.40 GHz base and 4.80 GHz boost.

Cache hierarchies show different design priorities. The Ryzen 3 3100U allocates 96 KB of L1 and 512 KB of L2 per core, with 4 MB of shared L3. The Intel chip assigns 80 KB of L1 and 2 MB of L2 per core, plus 20 MB of shared L3. The larger L2 allocation per core and five times the L3 capacity give Intel a notable memory subsystem advantage.

Memory support differs in scope. The Ryzen 3 3100U supports DDR4 only, with dual-channel access and 38.4 GB/s bandwidth. The Core i5-14450HX supports both DDR4 and DDR5, also dual-channel, though bandwidth figures are not recorded. ECC memory is supported on the Intel part but not on the AMD part. PCIe connectivity also differs: the AMD chip uses Gen 3, while Intel provides Gen 5 with 16 CPU lanes.

Integrated graphics take different forms. The Ryzen 3 3100U pairs with Radeon Vega 8, while the Core i5-14450HX uses UHD Graphics 710. The AMD chip has an unlocked multiplier set to false, while the Intel multiplier is unlocked.

The Verdict

The benchmark database shows a decisive verdict: the Intel Core i5-14450HX outperforms the AMD Ryzen 3 3100U in every recorded test. The Intel part holds an 82nd percentile ranking among all CPUs, while the AMD chip sits at the 62nd percentile. The average benchmark scores of 32040 versus 6247 place these chips in entirely different performance classes.

Users requiring maximum throughput for demanding workloads should select the Core i5-14450HX. Its 10-core, 16-thread configuration with 4.80 GHz boost delivers results that the 2-core, 2-thread Ryzen 3 3100U cannot approach. The Intel part also brings ECC memory support and DDR5 compatibility, which matter for reliability-focused deployments.

The Ryzen 3 3100U fits scenarios where low power consumption is the priority. Its 15 TDP represents a fraction of the Intel chip's 55 TDP. The AMD part uses an older 12 nm process but consumes far less power, making it suitable for compact, battery-conscious mobile designs. The Radeon Vega 8 integrated graphics may offer a different feature set compared to UHD Graphics 710, though no direct graphics benchmarks are recorded.

The data does not support any scenario where the Ryzen 3 3100U wins on compute performance. The closest margin is in single-thread testing, yet even there the Intel chip leads by 56.3%. For any application that scales with core count, clock speed, or cache size, the Core i5-14450HX is the only rational choice.

Where Each One Wins

The Intel Core i5-14450HX wins every benchmark category recorded in the database. Floating point math delivers its strongest relative advantage, with Intel leading by 89.9%. Integer math follows closely at 88.7%. These results make the Intel chip the clear choice for scientific computing, financial modeling, and any workload dominated by arithmetic operations.

Data compression and encryption workloads favor Intel heavily, with 86.2% and 87.3% advantages respectively. Extended instruction processing shows an 87.7% lead. These outcomes point to Intel as the preferred option for database operations, file archiving, and security-related processing.

Multithread performance gives Intel an 85.9% edge, reinforcing its suitability for rendering, video encoding, and parallel compilation tasks. Physics simulation shows an 84.3% advantage. The Core i5-14450HX with 10 cores and 16 threads delivers 7.1 times the multithread score of the 2-thread Ryzen 3 3100U.

The AMD Ryzen 3 3100U does not record a single benchmark victory. Its only potential justification comes from power efficiency, where the 15 TDP versus 55 TDP difference indicates substantially lower energy consumption. The AMD part also uses an older Picasso architecture with Radeon Vega 8 graphics, which may serve basic display output needs without requiring a discrete GPU.

For users prioritizing raw compute, the choice is unambiguous. The Intel Core i5-14450HX delivers superior results across every measured workload, with margins ranging from 56.3% in single-thread to 89.9% in floating point math. The Ryzen 3 3100U remains an option only where the 15 TDP power envelope is the overriding constraint.
