Intel Core i5-14401E vs Intel Core i9-10900KF Comparison

Head-to-Head Benchmarks

The comparison between the Intel Core i9-10900KF and Intel Core i5-14401E is unusually one-sided in the six directly measured benchmarks, all of which come from the Cinebench suite. The i9-10900KF wins every single head-to-head test, with a consistent 3.9% margin across all six runs. This uniformity is striking — from Cinebench R15 single-core (268 vs 258) to Cinebench R23 multi-core (18867 vs 18161), the delta never wavers from 3.9%. Such consistency suggests the performance gap is structural rather than workload-dependent, reflecting fundamental architectural and configuration differences between the two parts.

In multi-threaded workloads, the i9-10900KF’s advantage is clear but modest. Its Cinebench R23 multi-core score of 18867 beats the i5-14401E’s 18161 by 706 points. The R20 multi-core test shows a similar pattern: 7924 vs 7627, a 297-point gap. The R15 multi-core run yields 1901 vs 1830, a 71-point difference. These are not dramatic victories — 3.9% is a meaningful but not overwhelming lead — yet the i9-10900KF maintains it across every iteration of the Cinebench suite, from the older R15 to the newer R23.

Single-threaded performance tells the same story. The i9-10900KF posts 2663 in Cinebench R23 single-core versus 2564 for the i5-14401E. In R20 single-core, the margin is 1118 vs 1076, and in R15 single-core it’s 268 vs 258. Again, every result lands at exactly 3.9% in favor of the i9-10900KF. This consistency is notable because the i5-14401E has a newer microarchitecture with a higher per-core L1 cache (80 KB per core vs 64 KB per core) and a smaller process node (10 nm vs 14 nm), yet it still trails in raw single-threaded throughput.

Looking beyond the direct head-to-head, the broader benchmark data reinforces the i9-10900KF’s edge. The i9-10900KF has an average benchmark score of 5316 across 14 tests, while the i5-14401E averages 5253 across just 6 tests. That’s a 63-point average gap, or roughly 1.2% — smaller than the 3.9% head-to-head margin, but still favoring the older chip. The i9-10900KF’s percentile ranking versus all CPUs is 60th, identical to the i5-14401E’s 60th percentile. Both chips sit at the same overall performance tier, despite the i9-10900KF’s wins in every direct comparison.

The i9-10900KF’s nearest rivals in the overall database include the AMD EPYC 7281 (average score 5315, 0% delta), the AMD Ryzen Threadripper 1920X (5306, 0.2% delta), the Intel Core i9-9900X (5301, 0.3% delta), and the Intel Core i9-13900TE (5342, -0.5% delta). The i5-14401E’s nearest rivals are the Intel Xeon E5-2699A v4 (5259, -0.1% delta), the Intel Core i7-11700B (5241, 0.2% delta), the Intel Core i9-10850K (5240, 0.2% delta), and the Intel Core i5-13400T (5210, 0.8% delta). The i9-10900KF’s rival set averages slightly higher scores, which is consistent with its own higher average.

Where Each One Wins

The i9-10900KF wins in every category that the benchmark data measures. All six Cinebench tests — three multi-core and three single-core — go to the i9-10900KF. The wins are uniform at 3.9% across the board, so there is no test type where the i5-14401E manages to close the gap or flip the result. In multi-threaded rendering, the i9-10900KF’s 10 cores and 20 threads provide a structural advantage over the i5-14401E’s 6 cores and 12 threads, and the benchmark numbers reflect that. In single-threaded tasks, the i9-10900KF’s 5.30 GHz boost clock outperforms the i5-14401E’s 4.70 GHz boost clock, despite the newer architecture of the latter.

The i5-14401E’s wins are not in raw performance but in platform characteristics. It supports both DDR4 and DDR5 memory, while the i9-10900KF is limited to DDR4. The i5-14401E has integrated graphics (UHD Graphics 730), whereas the i9-10900KF has none — a relevant differentiator for systems that need a display output without a discrete GPU. The i5-14401E also supports ECC memory, which the i9-10900KF does not. In terms of PCIe, the i5-14401E offers Gen 5 with 16 lanes, while the i9-10900KF is limited to Gen 3 with 16 lanes. The i5-14401E is also an active product, while the i9-10900KF is end-of-life.

For users prioritizing raw compute, the i9-10900KF is the clear choice based on the data. For users prioritizing modern platform features, memory flexibility, or integrated graphics, the i5-14401E holds the advantage — but that advantage is not reflected in any of the benchmark scores.

Specification Differences

The two processors differ substantially on nearly every specification. The i9-10900KF has 10 cores and 20 threads, while the i5-14401E has 6 cores and 12 threads. Base clocks differ significantly: the i9-10900KF runs at 3.70 GHz, the i5-14401E at 2.50 GHz. Boost clocks show a smaller gap: 5.30 GHz for the i9-10900KF versus 4.70 GHz for the i5-14401E. Thermal design power is another major divergence — the i9-10900KF is rated at 125 watts, the i5-14401E at 65 watts.

Sockets are incompatible: the i9-10900KF uses Intel Socket 1200, while the i5-14401E uses Intel Socket 1700. Memory support differs as noted: the i9-10900KF is DDR4-only, while the i5-14401E supports DDR4 and DDR5. The i9-10900KF has a listed memory bandwidth of 46.9 GB/s; the i5-14401E’s bandwidth is not provided. ECC memory is supported on the i5-14401E but not on the i9-10900KF. PCIe generation and lanes also differ: the i9-10900KF has Gen 3 with 16 lanes, the i5-14401E has Gen 5 with 16 lanes. The i5-14401E has integrated UHD Graphics 730; the i9-10900KF has none. The i9-10900KF has an unlocked multiplier, while the i5-14401E’s multiplier is locked.

The i9-10900KF was released on 2020-04-29 with a launch MSRP of $509. The i5-14401E was released on 2024-06-30 with no listed launch MSRP. The i9-10900KF’s part number is SRH92; the i5-14401E’s is Q49JSRNJS. The die size for the i5-14401E is listed at 215 mm², while the i9-10900KF’s die size is not provided.

Architecture Differences

The architectural divide is generational. The i9-10900KF is built on Comet Lake, a 14 nm process from Intel, with a codename of Comet Lake and generation "Core i9 (Comet Lake)". The i5-14401E uses Raptor Lake, specifically the Raptor Lake-R refresh, on a 10 nm process, with generation "Core i5 (Raptor Lake Refresh)". Both are manufactured by Intel, but the process node difference is significant — 14 nm versus 10 nm — which typically implies better power efficiency and density for the newer part.

Cache layouts differ per core. The i9-10900KF has 64 KB of L1 cache per core and 256 KB of L2 cache per core. The i5-14401E has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The shared L3 cache is identical at 20 MB for both chips. Total L3 and 3D V-Cache fields are not listed for either processor.

The i5-14401E’s per-core caches are larger, but the i9-10900KF compensates with more cores. The 10 nm node of the i5-14401E, combined with its lower 65-watt TDP, suggests a more efficient design. However, the benchmark data shows that the i9-10900KF still outperforms in every measured workload despite its older 14 nm process and higher 125-watt TDP. The i5-14401E’s integrated UHD Graphics 730 is an architectural feature absent on the i9-10900KF, as is its ECC memory support and Gen 5 PCIe connectivity.

The Verdict

The data points to a clear conclusion: the Intel Core i9-10900KF is the faster processor in every benchmark measured. Across all six Cinebench tests, it wins by a consistent 3.9% margin, whether the workload is single-threaded or multi-threaded. Its 10 cores and 20 threads give it a compute advantage that the i5-14401E’s newer 10 nm architecture and larger per-core caches cannot overcome in these tests. The i9-10900KF also carries a higher average benchmark score (5316 vs 5253) and matches the i5-14401E’s 60th percentile ranking among all CPUs.

However, the i5-14401E is not without merit. It is a newer, active product with a lower 65-watt TDP, integrated graphics, ECC memory support, DDR5 compatibility, and Gen 5 PCIe. For a system builder prioritizing a modern platform, power efficiency, or a CPU with onboard display output, the i5-14401E offers those features — but not benchmark leadership. The i9-10900KF, despite being end-of-life and drawing 125 watts, remains the superior choice for raw performance in every test the data covers. Users who need maximum compute from these two options should select the i9-10900KF. Users who value platform modernity, lower power draw, or integrated graphics should consider the i5-14401E, accepting its 3.9% performance deficit. The i9-10900KF’s launch MSRP of $509 provides a reference point, but the i5-14401E’s pricing is not listed, so no cost comparison is possible from the data.
