Intel Core i3-14100F vs Intel Core i5-1335U Comparison

The Verdict

The Intel Core i5-1335U and Intel Core i3-14100F are fundamentally different processors aimed at different systems, and the benchmark data reflects that split clearly. The Core i5-1335U wins 5 of the 17 head-to-head comparisons, while the Core i3-14100F takes 12. However, the i5-1335U's wins are concentrated in specific workloads, and the i3-14100F's victories are often by larger margins.

For users building a desktop system with a discrete GPU, the Intel Core i3-14100F is the stronger choice. Its Cinebench R23 multi-core score of 13084 is 32.1% ahead of the i5-1335U's 8889.5, a decisive margin in heavily threaded rendering. Single-core performance also favors the i3-14100F, with a Cinebench R23 single-core score of 1847 versus 1684.5, an 8.8% advantage. The i3-14100F also holds a 72nd percentile ranking among all CPUs, just below the i5-1335U's 73rd percentile, but its average benchmark score of 18519 trails the i5-1335U's 18982 by a slim margin. The i3-14100F's launch MSRP is $109. The i5-1335U's launch MSRP is $340.

For a mobile or compact system where integrated graphics are required, the Intel Core i5-1335U is the only viable option of the two. The i3-14100F has no integrated graphics, so it cannot operate without a discrete GPU. The i5-1335U includes Iris Xe Graphics 80EU, making it the pick for thin-and-light laptops or all-in-one systems. Its 10-core, 12-thread configuration with a 15 W TDP also positions it for power-constrained environments, while the i3-14100F's 58 W TDP and desktop Socket 1700 require a more substantial cooling and power delivery setup.

Architecture Differences

Both processors share the Raptor Lake architecture and are built on Intel's 10 nm process node, but they diverge in nearly every other physical and functional characteristic. The Intel Core i5-1335U is a Raptor Lake-U part, designed for mobile systems, while the Intel Core i3-14100F is a Raptor Lake Refresh part, built for desktop platforms.

The core configurations are starkly different. The i5-1335U packs 10 cores and 12 threads, while the i3-14100F has only 4 cores and 8 threads. This gives the mobile chip a significant count advantage, but the desktop chip compensates with higher clock speeds. The i5-1335U has a base clock of 1300 MHz and a boost clock of 4.60 GHz, whereas the i3-14100F starts at 3.50 GHz and boosts to 4.70 GHz. The i3-14100F's higher base clock, more than 2.6 times that of the i5-1335U, explains much of its single-thread advantage in sustained workloads.

Cache hierarchies are identical per core. Both chips have 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, with 12 MB of shared L3 cache. The i3-14100F is listed with a die size of 163 mm², while the i5-1335U has no recorded die size. Both support DDR4 and DDR5 memory in dual-channel mode, but the i3-14100F supports ECC memory while the i5-1335U does not.

Platform connectivity is another major differentiator. The i5-1335U uses Intel BGA 1744 and offers PCIe Gen 4 with 8 lanes from the CPU. The i3-14100F uses Intel Socket 1700 and offers PCIe Gen 5 with 16 lanes from the CPU. The desktop chip's broader PCIe lane count and newer generation support make it more suitable for high-bandwidth add-in cards. The i5-1335U includes Iris Xe Graphics 80EU, while the i3-14100F has no integrated graphics at all.

Production status for both is Active. The i5-1335U was released on 2023-01-03, and the i3-14100F followed on 2024-01-07. Neither chip has an unlocked multiplier. The i5-1335U's part number is SRMEX, and the i3-14100F's is SRMX2.

Where Each One Wins

The Intel Core i5-1335U wins in 5 head-to-head benchmarks, and those wins cluster around integer-heavy and encryption workloads. It takes PassMark data encryption by 12.2% with a score of 10009 versus 8922, and PassMark integer math by 13% with 51244 versus 45357. It also wins PassMark random string sorting by 2% with 17953 versus 17596. In Cinebench R15, the i5-1335U wins both multi-core (1464 versus 1318, an 11.1% edge) and single-core (238 versus 186, a 28% edge). These results suggest the mobile chip's higher core count and thread count give it an edge in older benchmark versions and in algorithms that scale with parallelism or favor its specific scheduling.

The Intel Core i3-14100F wins the remaining 12 benchmarks, often by substantial margins. Its Cinebench R23 multi-core win of 32.1% is the largest of any comparison, and it also wins Cinebench R20 multi-core by 10.2% with 5495 versus 4935. Single-core wins are consistent across newer Cinebench versions: R20 single-core goes to the i3-14100F by 10.2% (775 versus 696), and R23 single-core by 8.8% (1847 versus 1684.5). PassMark single-thread also favors the desktop chip by 11.7% with 3778 versus 3336.

The i3-14100F dominates in extended instruction workloads, winning PassMark extended instructions by 25.1% with 11984 versus 8974. It wins PassMark find prime numbers by 21.3% (61 versus 48), PassMark physics by 22.3% (1077 versus 837), and PassMark multithread by 7.4% (15420 versus 14281). Data compression favors the desktop chip by 9.4% (176106 versus 159593), and floating point math is nearly a tie, with the i3-14100F winning by just 0.5% (35370 versus 35176).

In practical terms, the i5-1335U is better suited for encryption-heavy tasks, integer math, and older Cinebench workloads. The i3-14100F is better for rendering, physics simulation, extended instruction sets, prime number calculations, and general multithreaded throughput. The desktop chip's higher boost clock and full 4.70 GHz capability give it the edge in most modern single-threaded applications.

PassMark floating point math is the closest comparison, with the i3-14100F winning by just 0.5% (35370 versus 35176). PassMark single-thread is a 11.7% win for the desktop chip with 3778 versus 3336, and the duplicate PassMark singlethread result matches exactly.

The data shows a clear split: the i5-1335U dominates in encryption, integer math, and legacy Cinebench tests, while the i3-14100F dominates in rendering, physics, extended instructions, and modern single-threaded workloads. The i3-14100F's average benchmark score of 18519 is close to the i5-1335U's 18982, but its wins are in heavier, more demanding tasks. The i5-1335U's percentile ranking of 73 against the i3-14100F's 72 reflects the overall similarity in average scores, but the distribution of wins matters more for real-world use.
