Intel Core i5-14400F and Intel Core i5-14490F are both Raptor Lake Refresh desktop parts on Intel Socket 1700, sharing the same 10-core, 16-thread configuration. The database shows the 14490F as the stronger performer across every recorded workload, with a higher average benchmark score and a higher percentile ranking. The 14400F remains a capable part, but the data indicates the 14490F is the more potent silicon in this comparison.

Where Each One Wins

The recorded benchmark data shows a clean sweep for the Intel Core i5-14490F, which wins all 17 head-to-head comparisons. There is no workload category in the database where the 14400F takes the lead. The 14490F’s advantages are consistent across both single-threaded and multi-threaded tests, suggesting its higher boost clock and larger cache provide a universal performance uplift rather than a niche benefit.

For users focused on general desktop responsiveness and lightly threaded applications, the 14490F delivers a modest but real edge in single-core tests. The Cinebench R23 single-core score of 3247 for the 14490F versus 3055 for the 14400F shows a 5.9 percent advantage, which translates to snappier performance in typical daily tasks. The PassMark single-thread score also favors the 14490F by 4.4 percent.

In multi-threaded workloads, the 14490F extends its lead. The Cinebench R23 multi-core score of 23000 against 21645 represents a 5.9 percent gap, while the PassMark multithread score shows a wider 11.1 percent difference. This indicates that the 14490F is particularly well-suited for content creation, rendering, and other tasks that scale across all 16 threads. The PassMark physics test shows the largest divergence, with the 14490F scoring 2093 versus 1523 for the 14400F, a 27.2 percent gap that suggests a notable advantage in simulation or physics-heavy applications.

Head-to-Head Benchmarks

The head-to-head data confirms the 14490F’s dominance, but the size of the advantage varies by test. In Cinebench R15 multi-core, the 14490F scores 2318 against 2181 for the 14400F, a 5.9 percent lead. The single-core R15 result shows a similar 6.1 percent gap, with scores of 327 and 307 respectively. These differences persist in R20, where the multi-core scores are 9660 versus 9090 (5.9 percent) and single-core scores are 1363 versus 1283 (5.9 percent).

The PassMark suite reveals where the 14490F stretches its lead further. The most dramatic result is in the find prime numbers test, where the 14490F scores 122 compared to 86 for the 14400F, a 29.5 percent advantage. The physics test also shows a large gap at 27.2 percent, with scores of 2093 and 1523. These two tests indicate that the 14490F’s architectural advantages, likely the larger L3 cache and higher clock, have a pronounced effect on workloads involving complex calculations and iterative processes.

In more general productivity tasks, the 14490F maintains a solid but smaller lead. The integer math test shows a 7.2 percent gap (87844 versus 81524), while floating point math is 7.9 percent higher (66558 versus 61319). Data compression and encryption tests show 7.2 percent and 7 percent advantages respectively. The extended instructions test shows an 8.3 percent difference, and random string sorting is 8.2 percent ahead. The smallest advantage is in single-threaded performance, where the 14490F leads by 4.4 percent in both PassMark single-thread tests.

Specification Differences

The two processors are identical in many core specifications, but key differences exist. Both have 10 cores and 16 threads, a base clock of 2.50 GHz, a TDP of 65 watts, and use Intel Socket 1700. The process node is 10 nm for both, with a die size of 215 mm². Both support DDR4 and DDR5 memory in a dual-channel configuration, and both have PCIe Gen 5 with 16 lanes from the CPU. Neither has integrated graphics, and both are desktop parts with locked multipliers.

The first major difference is the boost clock: the 14490F reaches 5.00 GHz, which is 0.30 GHz higher than the 14400F’s 4.70 GHz. The second difference is L3 cache: the 14490F has 24 MB shared, while the 14400F has 20 MB shared. The L1 and L2 caches are the same at 80 KB per core and 1.25 MB per core respectively. ECC memory support differs, with the 14400F supporting it and the 14490F not. The release dates are also close, with the 14400F released on 2024-01-07 and the 14490F on 2023-12-31. The 14400F has a launch MSRP of $196, while the 14490F has no recorded launch MSRP in the database.

Architecture Differences

Both processors are built on the Raptor Lake architecture, specifically the Raptor Lake-R codename, and belong to the Core i5 (Raptor Lake Refresh) generation. They use the same 10 nm process node from Intel and share the same 215 mm² die size. The core configuration is identical: 10 cores and 16 threads, with L1 cache at 80 KB per core and L2 cache at 1.25 MB per core.

The architectural divergence lies in the L3 cache and the boost clock. The 14490F’s 24 MB of shared L3 cache is 4 MB larger than the 14400F’s 20 MB, which contributes to its superior performance in cache-sensitive workloads. The higher 5.00 GHz boost clock on the 14490F also provides a clock-speed advantage over the 14400F’s 4.70 GHz. These two factors, combined with the identical core topology, explain why the 14490F consistently outperforms the 14400F across all recorded benchmarks. The 14490F also lacks ECC memory support, a feature present on the 14400F, which positions the 14490F as a performance-focused variant rather than a workstation-oriented one.
