Architecture Differences

The two processors are built on the same fundamental Raptor Lake architecture, but they are configured for entirely different platforms and workloads. Both use a 10 nm process at Intel, yet their physical and functional characteristics diverge sharply.

The Intel Core 3 100U is a Raptor Lake-U part, designed for the mobile market segment. It is a 6-core, 8-thread processor with a base clock of 1.20 GHz and a boost clock of 4.70 GHz. Its thermal design power is a low 15 watts, which is typical for ultraportable devices. The chip uses the Intel BGA 1744 socket, meaning it is soldered directly to the motherboard. It includes integrated UHD Graphics 64EU, making it a self-contained solution for laptops without discrete graphics. The memory support includes both DDR4 and DDR5 in a dual-channel configuration, and the PCIe interface is Gen 4 with 8 lanes from the CPU.

The Intel Core i5-14490F, on the other hand, is a Raptor Lake-R part from the Core 14th Gen series, aimed at the desktop market. It has 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 5.00 GHz. The TDP is 65 watts, which requires a more robust cooling solution. It uses the Intel Socket 1700 and has a die size of 215 mm². This processor lacks integrated graphics entirely, which is a defining characteristic of the "F" suffix. It also supports DDR4 and DDR5 memory in dual-channel mode, but its PCIe implementation is more advanced, offering Gen 5 with 16 lanes from the CPU.

Cache hierarchies are similar in structure, with both using 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The critical difference lies in L3 cache: the Core 3 100U has 10 MB shared, while the Core i5-14490F has 24 MB shared. This larger pool of L3 cache on the desktop chip is a significant contributor to its performance advantage in multi-threaded and data-heavy workloads.

Head-to-Head Benchmarks

The benchmark results are unequivocally in favor of the Intel Core i5-14490F. Across all 17 recorded tests, the desktop processor wins by a comfortable margin. The data reveals a pattern where the gap is larger in multi-threaded workloads and narrower in single-thread tests.

In Cinebench tests, the Core i5-14490F shows a consistent lead of approximately 53.8% to 54.1%. For example, in Cinebench R23 multi-core, the desktop chip scores 23000 versus 10624 for the Core 3 100U. The single-core R23 test shows a score of 3247 versus 1499. This indicates a roughly 54% advantage in both scenarios, highlighting the combination of higher clock speeds and more cores.

The PassMark suite of tests shows similar dominance. In data compression, the Core i5-14490F scores 340026 versus 136497, a delta of 59.9%. Data encryption shows 18225 versus 8128, a 55.4% lead. Extended instructions, which tests SIMD and CPU-specific enhancements, shows the largest gap at 63.7%, with scores of 21731 versus 7894.

The floating-point math test shows a 57.4% difference, with the desktop chip scoring 66558 against 28322. Integer math shows a 54.9% advantage, scoring 87844 versus 39580. The physics test, which often correlates with gaming performance, shows the Core i5-14490F scoring 2093 against 876, a 58.1% lead.

The smallest gap in the entire dataset is in the PassMark single-thread test. Here, the Core i5-14490F scores 3873, and the Core 3 100U scores 3506. The delta is only 9.5%. This suggests that while the desktop chip has a higher boost clock (5.00 GHz versus 4.70 GHz), the per-core efficiency of the Raptor Lake architecture is relatively close. The single-thread performance of the mobile chip is competitive, but the desktop part still leads.

The multi-thread PassMark score shows a 56.3% advantage, with 28662 versus 12522. Random string sorting shows a 57.3% lead, with 35608 versus 15191. Find prime numbers shows a 57.4% lead, with 122 versus 52.

The Verdict

The data presents a clear separation between these two Intel processors. The Intel Core i5-14490F is the superior performer in every recorded benchmark, with a commanding average benchmark score of 38149 compared to 16148 for the Intel Core 3 100U. Its percentile ranking of 86 versus 70 further underscores its higher standing in the overall CPU landscape.

The Intel Core i5-14490F is designed for users who require maximum compute throughput. The benchmarks indicate it delivers more than double the multi-threaded performance in Cinebench R23 (23000 versus 10624) and nearly double the PassMark multi-thread score (28662 versus 12522). The 24 MB of L3 cache and support for PCIe Gen 5 with 16 lanes position it for demanding desktop workloads, including content creation and high-end gaming, though the lack of integrated graphics means a discrete GPU is mandatory.

The Intel Core 3 100U serves a different purpose entirely. With a 15-watt TDP and integrated UHD Graphics 64EU, it is built for mobile efficiency. Its single-thread score of 3506 in PassMark is within 9.5% of the desktop chip, showing that for lightly-threaded tasks, the mobile part holds its own relative to its power envelope. The 6-core, 8-thread configuration and 10 MB of L3 cache are adequate for everyday productivity, but the multi-thread scores indicate it will lag significantly in heavily parallel workloads.

The recorded data shows that the Core i5-14490F is the clear choice for desktop builds where performance is the priority. The Core 3 100U is the appropriate option for mobile systems where low power consumption and integrated graphics are essential. There is no overlap in their performance profiles, and the benchmark results confirm they are optimized for entirely different use cases.
