Architecture Differences

Both processors belong to Intel's Core 14th Gen series and share the Raptor Lake architecture on Intel's 10 nm process node. The core and thread counts are identical at 10 cores and 16 threads. The differences begin with the physical package. The 14450HX uses the Intel BGA 1964 socket and targets the mobile segment, while the 14490F uses Intel Socket 1700 and targets desktop systems.

Clock speeds differ. The 14450HX has a base clock of 2.40 GHz and a boost clock of 4.80 GHz. The 14490F runs at 2.50 GHz base and 5.00 GHz boost. The thermal design power also differs, with the mobile part rated at 55 W and the desktop part at 65 W. Die size varies as well: the 14450HX measures 257 mm², while the 14490F is smaller at 215 mm².

Cache configurations diverge in the L2 and L3 levels. Both have 80 KB of L1 per core, but the 14450HX carries 2 MB of L2 per core, whereas the 14490F carries 1.25 MB per core. The shared L3 cache reverses this relationship: the 14450HX has 20 MB, while the 14490F offers 24 MB. This larger L3 pool on the desktop part likely contributes to its advantage in cache-sensitive workloads such as random string sorting.

Integrated graphics separate the two clearly. The 14450HX includes Intel UHD Graphics 710, while the 14490F has no integrated graphics at all, indicated by N/A. ECC memory support is present on the 14450HX but absent on the 14490F. Both support DDR4 and DDR5 memory through a dual-channel bus and both provide PCIe Gen 5 with 16 lanes from the CPU.

The multiplier is unlocked on the 14450HX, while the 14490F is locked. Release dates are close, with the 14450HX dated 2024-01-07 and the 14490F dated 2023-12-31. Both parts remain in active production. Part numbers are SRMXK for the 14450HX and SRN35 for the 14490F.

The Verdict

The recorded data confirms that the Intel Core i5-14490F is the stronger performer in every measured benchmark. Its average benchmark score of 38149 sits at the 86th percentile of all CPUs, while the 14450HX averages 32040 at the 82nd percentile. The 14490F leads by 12.6% across all Cinebench tests and by margins ranging from 5.9% to 29.5% across the PassMark suite.

The 14450HX does hold advantages in specific features. It includes integrated graphics, supports ECC memory, uses an unlocked multiplier, and carries more L2 cache per core at 2 MB versus 1.25 MB. These traits make it suitable for mobile systems where a discrete GPU may be absent and where error-correcting memory is desirable. Its 55 W TDP also fits the thermal envelope of laptop chassis.

The 14490F counters with a higher boost clock, more L3 cache, and a smaller die. Its 65 W TDP is modest for a desktop part, and its locked multiplier is a minor limitation for overclocking-oriented builders. The absence of integrated graphics means a discrete GPU is mandatory, but desktop systems typically include one anyway.

The percentile data places the 14490F among CPUs like the Intel Core Ultra 5 245T and Intel Core i5-13600KF, all within 0.3% of each other. The 14450HX sits alongside the Intel Core i7-13705H, Intel Core i5-14400, and Intel Core i7-12800H, all within 0.6% of its average score. This places the two processors in different performance tiers despite their shared core count and architecture.

Where Each One Wins

The Intel Core i5-14490F wins in every recorded benchmark category. Its largest margins appear in PassMark physics (29.5%), extended instructions (20.8%), prime number finding (19.7%), and data compression (18.1%). These results point to strengths in CPU-bound simulation, encryption workloads, and compression tasks. Its Cinebench performance, consistently 12.6% ahead, makes it the clear choice for rendering workloads measured by Cinebench R15, R20, and R23.

The Intel Core i5-14450HX does not win any benchmark, but its feature set suits specific use cases. The integrated UHD Graphics 710 allows operation without a discrete GPU, which is relevant for mobile workstations or compact systems where power consumption matters. ECC memory support enables use in error-sensitive computing environments. The unlocked multiplier provides flexibility for tuning within the thermal limits of a laptop. The larger L2 cache of 2 MB per core may benefit workloads with high per-core working sets, though the recorded benchmarks do not isolate this advantage.

The market segments dictate the practical split. The 14450HX targets mobile systems with its BGA 1964 socket, 55 W TDP, and integrated graphics. The 14490F targets desktop builds with Socket 1700, a 65 W TDP, and no integrated graphics. Desktop builders with a discrete GPU and a preference for higher multi-threaded performance should choose the 14490F based on the benchmark data. Mobile users who need integrated graphics or ECC support have only one option in this comparison, the 14450HX, even though its performance scores are lower across the board.
