Architecture Differences

Both processors are built on the Raptor Lake architecture and use Intel's 10 nm process node with the Intel Socket 1700. The Core 3 100UL belongs to the Raptor Lake-PS codename, while the Core i5-14401TE uses the Raptor Lake-R codename and is part of the Raptor Lake Refresh generation. The i5-14401TE is classified under the Core 14th Gen series, whereas the Core 3 100UL is a standalone Core 3 part.

The core configuration is identical at 6 physical cores, but the threading capability differs. The Core 3 100UL supports 8 threads, indicating it uses a configuration where not all cores have Hyper-Threading enabled. The Core i5-14401TE supports 12 threads, which means all 6 cores are capable of handling 2 threads each. This is a fundamental architectural difference that affects multi-threaded workload performance.

Cache hierarchy shows a major divergence. The L1 cache is 80 KB per core for both, and the L2 cache is 1.25 MB per core for both. However, the shared L3 cache is 10 MB on the Core 3 100UL versus 20 MB on the Core i5-14401TE. This doubled L3 capacity on the i5 provides more room for frequently accessed data, which can improve performance in cache-sensitive applications.

The memory controllers support DDR4 and DDR5 in dual-channel mode on both CPUs. ECC memory support is present only on the Core i5-14401TE, which is a feature typically aimed at workstation or server-class workloads where data integrity is critical. The Core 3 100UL lacks ECC support.

PCIe capabilities differ significantly. The Core 3 100UL provides PCIe Gen 4 with 8 lanes from the CPU. The Core i5-14401TE provides PCIe Gen 5 with 16 lanes from the CPU, doubling both the lane count and the generation bandwidth. This makes the i5 more suitable for high-throughput expansion cards like modern GPUs or NVMe storage.

The integrated graphics also differ. The Core 3 100UL uses UHD Graphics 64EU, while the Core i5-14401TE uses UHD Graphics 730. The die size for the i5-14401TE is recorded at 215 mm², while the Core 3 100UL has no die size listed in the database.

The release dates are close: the Core 3 100UL launched on 2024-04-07, and the Core i5-14401TE launched on 2024-06-30. Both are currently marked as Active in production status. Neither has an unlocked multiplier, so overclocking is not supported on either part.

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either processor. The average benchmark score is 0 for both, and the head-to-head benchmark array is empty. Both CPUs sit at the 50th percentile among all CPUs in the database, which is a neutral position indicating they are neither top-tier nor bottom-tier performers in the overall distribution.

Because no benchmark data is available, a direct numerical comparison of performance is not possible from the recorded measurements. The wins counter shows 0 for both the Core 3 100UL and the Core i5-14401TE, meaning the database has not registered any benchmark category where one chip outperforms the other.

However, the specification differences provide some basis for expected behavior in specific workload types. The Core i5-14401TE has 4 additional threads, which directly affects multi-threaded workloads. In tasks that scale well with thread count, such as video encoding, 3D rendering, or scientific simulations, the i5's 12 threads versus 8 threads would likely provide a measurable advantage. The exact percentage cannot be stated because no benchmark scores exist in the database.

The L3 cache difference is another point of distinction. The i5-14401TE has 20 MB of L3 versus 10 MB on the Core 3 100UL. Larger cache hierarchies typically reduce memory latency for repeated data access patterns. This could benefit workloads with large working sets, such as database queries or certain compilation tasks, where the i5 may show improved efficiency.

The base clock difference is notable: 2.00 GHz on the i5 versus 1.20 GHz on the Core 3 100UL. Both boost to 4.50 GHz, so single-threaded peak performance is nominally identical. But sustained all-core loads at base frequencies would favor the i5 due to its higher base clock, assuming thermal and power limits allow sustained operation.

The TDP values differ substantially: 15 watts for the Core 3 100UL versus 45 watts for the Core i5-14401TE. This 30-watt gap indicates the i5 is designed for higher sustained power delivery, which typically translates to higher sustained performance under load. The Core 3 100UL is a low-power part that would generate less heat and consume less energy, making it suitable for compact or passively cooled systems.

PCIe capabilities also play a role in real-world performance. The i5-14401TE's PCIe Gen 5 with 16 lanes allows for faster data transfer to compatible devices. A Gen 5 SSD or GPU would be bottlenecked by the Core 3 100UL's Gen 4 with 8 lanes. For users with high-end expansion cards, the i5 is the only viable choice between the two.

The Verdict

The recorded data shows a clear separation in positioning between these two processors. The Intel Core i5-14401TE is the more capable processor for multi-threaded and high-throughput workloads. Its 12 threads, 20 MB of L3 cache, higher base clock of 2.00 GHz, and 45-watt TDP indicate it is built for sustained performance in demanding applications. The PCIe Gen 5 support with 16 lanes further extends its capability for modern peripherals.

The Intel Core 3 100UL is positioned as a low-power desktop part. Its 15-watt TDP, 8 threads, and 10 MB of L3 cache make it suitable for basic desktop tasks, light productivity, or systems where power consumption and heat output are primary concerns. The PCIe Gen 4 with 8 lanes is adequate for standard SSDs and mid-range GPUs but limits expansion potential.

For users who prioritize multi-core performance, memory integrity via ECC support, or high-bandwidth PCIe devices, the i5-14401TE is the appropriate choice based on the specifications. The i5 supports ECC memory, which the Core 3 does not. This makes the i5 suitable for error-sensitive environments like data processing or server-adjacent roles.

For users who need a simple, energy-efficient desktop processor with a 4.50 GHz boost clock and dual-channel DDR4/DDR5 support, the Core 3 100UL offers a lower-power alternative. Its 15-watt TDP is a significant differentiator, suggesting it can operate in thermally constrained chassis.

Both processors are Active in production, share the same socket, and use the same process node. Neither has an unlocked multiplier. The decision between them rests on whether the extra threads, cache, PCIe lanes, ECC support, and base clock of the i5 justify the higher power envelope. The database shows no benchmark scores, so the performance gap cannot be quantified, but the architectural advantages of the i5 are documented in the specification differences.
