Intel Core 3 100UL vs Intel Core i5-14501E Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries for these two processors, and neither has an average benchmark score on file. Both sit at the 50th percentile among all CPUs tracked in the database, which places them in the middle of the performance distribution, though that percentile alone does not indicate how they compare against each other. Without measured scores, the comparison must rest on the architectural and specification data recorded for each part.

What the recorded data does show is a substantial gap in thread count and clock speeds. The Intel Core 3 100UL uses 6 cores and 8 threads, while the Intel Core i5-14501E uses 6 cores and 12 threads. That difference of 4 additional threads comes from Hyper-Threading support on the i5 part, which the Core 3 does not appear to implement. In multi-threaded workloads that scale with thread count, the i5-14501E can expect a meaningful advantage, though the exact percentage cannot be quantified from the database since no benchmark scores are present.

Clock speeds also favor the i5-14501E by a wide margin. The Core 3 100UL has a base clock of 1.20 GHz and a boost clock of 4.50 GHz. The i5-14501E runs at a base clock of 3.30 GHz and boosts to 5.20 GHz. The base clock difference alone is 2.10 GHz, which means the i5-14501E sustains nearly three times the base frequency of the Core 3. In single-threaded workloads that rely on raw clock speed, the i5-14501E holds a clear edge. The boost clock advantage of 0.70 GHz further widens that gap during short burst workloads.

Cache capacity also differs significantly. The Core 3 100UL has 10 MB of shared L3 cache, while the i5-14501E has 24 MB of shared L3 cache. That is 14 MB more L3 on the i5 part, which can improve performance in workloads with larger working sets that repeatedly access the same data. Both processors share the same L1 cache structure at 80 KB per core and the same L2 cache at 1.25 MB per core, so the difference is isolated to the L3 level.

Both processors use the same 10 nm process node and are built by Intel. Both use the Raptor Lake architecture, with the Core 3 100UL carrying the Raptor Lake-PS codename and the i5-14501E using the Raptor Lake-R codename. The i5-14501E belongs to the Core 14th Gen series and is described as Raptor Lake Refresh, while the Core 3 100UL is listed as part of the Core 3 generation with the Raptor Lake-PS codename. The architectural lineage is shared, but the refresh designation on the i5 part suggests a more recent iteration of the same fundamental design.

The Verdict

The data points to the Intel Core i5-14501E as the stronger processor in nearly every measurable specification. It has more threads, higher base and boost clocks, more L3 cache, and a larger die size. The Core 3 100UL counters with a much lower TDP of 15 watts against 65 watts for the i5-14501E, which makes it the more power-efficient option on paper. However, the database does not include power consumption measurements or thermal performance data, so the practical impact of that TDP difference remains unquantified.

The i5-14501E also supports ECC memory, while the Core 3 100UL does not. That makes the i5 part the only choice for systems requiring error-correcting memory, such as certain workstation or server-oriented builds. The i5-14501E also provides PCIe Gen 5 with 16 lanes from the CPU, whereas the Core 3 100UL provides PCIe Gen 4 with 8 lanes. That is a significant I/O advantage for the i5 part, particularly for users who need high-bandwidth expansion slots or fast NVMe storage.

The Core 3 100UL has one clear advantage besides power: its release date is earlier. The Core 3 100UL launched on 2024-04-07, while the i5-14501E launched on 2024-06-30. That is a difference of roughly three months, but release timing does not affect performance. Both parts remain in active production, so availability should not be a differentiator.

For users who need maximum multi-threaded performance, higher clock speeds, larger cache, ECC support, or PCIe Gen 5 connectivity, the i5-14501E is the clear choice from the recorded data. For users who prioritize low power consumption above all other factors, the Core 3 100UL has the advantage with its 15 watt TDP. There is no benchmark data to suggest the Core 3 performs competitively in any compute-intensive scenario.

Where Each One Wins

The Intel Core i5-14501E wins in multi-threaded workloads due to its 12 threads versus 8 threads on the Core 3 100UL. Applications that can utilize more than 8 threads, such as video encoding, 3D rendering, compilation, and scientific computing, will see a benefit from the additional threads. The exact magnitude cannot be stated without benchmark scores, but the thread count difference is a structural advantage.

The i5-14501E also wins in single-threaded and lightly threaded workloads due to its higher clock speeds. A base clock of 3.30 GHz and a boost clock of 5.20 GHz give it a substantial frequency advantage over the Core 3 100UL's 1.20 GHz base and 4.50 GHz boost. Software that depends on single-core performance, such as many older games, spreadsheet calculations, and general desktop responsiveness, will favor the i5 part.

The larger L3 cache on the i5-14501E, 24 MB versus 10 MB, gives it an advantage in workloads with large working sets. Database queries, certain server workloads, and applications that frequently revisit the same data can benefit from the additional cache capacity. The i5-14501E also wins on I/O capabilities with PCIe Gen 5 and 16 CPU lanes, which supports faster storage devices and more expansion options.

The Core 3 100UL wins on power efficiency. Its 15 watt TDP is 50 watts lower than the i5-14501E's 65 watt TDP. That makes it suitable for builds where cooling is limited, power delivery is constrained, or noise is a concern. The Core 3 100UL also has an earlier release date, which may matter in procurement cycles that require a specific launch timeline, though that does not affect performance.

The integrated graphics differ as well. The Core 3 100UL uses UHD Graphics 64EU, while the i5-14501E uses UHD Graphics 770. The database does not include graphics benchmark scores, so the performance difference between these iGPU units cannot be quantified. However, the i5 part's graphics solution is a higher-tier model in Intel's naming scheme, which typically indicates more execution units and higher clocked graphics, though those details are not in the recorded data.
