Intel Core i5-14400T vs Intel Core i5-14490F Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core i5-14490F wins every single head-to-head test in the database, 17 wins to 0. The i5-14490F delivers a 25.3% advantage in Cinebench R23 multi-core (23000 vs 17189) and a matching 25.3% lead in single-core (3247 vs 2426). The gap persists across every PassMark workload, from a 9.3% lead in single-thread performance to a 40.6% lead in physics simulation.

The i5-14490F sits at the 86th percentile of all CPUs in the database, while the i5-14400T sits at the 79th. The i5-14490F's average benchmark score of 38149 places it alongside the Intel Core i5-13600KF (38103, a 0.1% difference) and the Intel Core Ultra 5 245T (38194, a 0.1% deficit). The i5-14400T's average of 27166 puts it in the company of the Intel Core i9-9900K (27097, 0.3% behind) and the AMD Ryzen 7 5700G (27051, 0.4% behind). The i5-14490F is the clear choice for anyone building around this socket and needing the stronger processor.

The i5-14400T does have one significant advantage: its 35 W TDP compared to 65 W for the i5-14490F. It also includes integrated graphics (UHD Graphics 730) while the i5-14490F has none, and it supports ECC memory. Those features matter for specific builds: low-power systems, compact desktops that need an iGPU for display output, or setups where ECC memory is required. For raw performance across every measured workload, the i5-14490F is the better part.

Architecture Differences

Both processors are built on the same Raptor Lake architecture, specifically the Raptor Lake-R codename, and both belong to the Core 14th Gen series with the same Core i5 (Raptor Lake Refresh) generation. Both use a 10 nm process node from Intel, and both have a die size of 215 mm². They share the same Intel Socket 1700, the same dual-channel memory bus, and the same PCIe Gen 5 with 16 lanes (CPU only) configuration. Neither has an unlocked multiplier, so overclocking is not a differentiator.

The core topology is identical: 10 cores and 16 threads on each part. The L1 cache is 80 KB per core on both, and the L2 cache is 1.25 MB per core on both. The L3 cache differs: the i5-14400T has 20 MB shared, while the i5-14490F has 24 MB shared. That 4 MB difference in shared L3 is one of the few architectural distinctions between the two.

Clock speeds diverge significantly. The i5-14400T has a 1.50 GHz base clock and a 4.50 GHz boost clock. The i5-14490F runs at a 2.50 GHz base and a 5.00 GHz boost. The 1.0 GHz higher base clock and 0.5 GHz higher boost clock on the i5-14490F explain much of the performance delta.

Power and feature differences are substantial. The i5-14400T carries a 35 W TDP, supports ECC memory, includes UHD Graphics 730 integrated graphics, and has a launch MSRP of $221. The i5-14490F has a 65 W TDP, no ECC support, no integrated graphics, and no recorded launch MSRP in the database. Both support DDR4 and DDR5 memory, and both are listed as Active production parts. The i5-14490F was released on 2023-12-31, while the i5-14400T followed on 2024-01-07.

The average benchmark scores put the gap in context. The i5-14490F averages 38149, which is 40.4% higher than the i5-14400T's 27166. The nearest rivals confirm the tier difference: the i5-14490F trades blows with the Intel Core i5-13600KF (38103, 0.1% behind) and the Intel Core Ultra 5 245T (38194, 0.1% ahead), while the i5-14400T matches the Intel Core i9-9900K (27097, 0.3% behind) and the AMD Ryzen 7 5700G (27051, 0.4% behind).

Where Each One Wins

The i5-14490F wins every benchmark category in the database. There is no recorded workload where the i5-14400T scores higher. The i5-14490F is the stronger processor for multi-threaded rendering, as the Cinebench R23 multi-core score of 23000 versus 17189 demonstrates. It is also stronger for single-threaded responsiveness, with a 3247 versus 2426 lead in Cinebench R23 single-core. PassMark workloads covering compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithreading, physics, random string sorting, and single-thread performance all favor the i5-14490F.

The i5-14400T's advantages are not measured in benchmark scores but in platform features. Its 35 W TDP suits systems with limited cooling or small power budgets. The integrated UHD Graphics 730 removes the need for a discrete graphics card in basic display output. ECC memory support matters for error-sensitive workloads in specific professional or server-like configurations. The i5-14400T also has a recorded launch MSRP of $221, while the i5-14490F has no recorded launch MSRP.

For a builder choosing between these two, the decision hinges on whether the i5-14400T's lower TDP, integrated graphics, and ECC support outweigh the i5-14490F's 25% to 40% performance advantage across all 17 recorded benchmarks. The data shows a clear performance hierarchy, with the i5-14490F occupying an 86th percentile position versus the i5-14400T's 79th percentile.
