Intel Core i5-14400 vs Intel Core i9-14901KE Comparison

# Head-to-Head Benchmarks

The Intel Core i5-14400 and Intel Core i9-14901KE present an unusual comparison because the database contains a full benchmark suite for the i5-14400, while the i9-14901KE has no recorded benchmark scores in the current data. The i5-14400 shows an average benchmark score of 32115 and sits at the 82nd percentile among all CPUs tracked in the database. Its closest rival in the database, the Intel Core i7-12800H, scores 32121, a delta of 0 percent, indicating near-identical overall performance. The i9-14901KE, by contrast, has an average benchmark score of 0 and falls at the 50th percentile, with no nearest rivals recorded and no head-to-head benchmark entries available.

Focusing on the i5-14400 measured results, the Cinebench R23 multicore score reaches 21315, while the single-core score is 3009. The Cinebench R20 multicore result is 8952, and the single-core result is 1263. Cinebench R15 multicore records 2148, with a single-core score of 303. Geekbench multicore shows 9807 and single-core 1905. PassMark results for the i5-14400 include multithread at 25080, single-thread at 3741, integer math at 82017, floating point math at 61549, extended instructions at 19816, data compression at 314995, data encryption at 16731, find prime numbers at 80, random string sorting at 32346, and physics at 1396.

The i9-14901KE has no benchmark entries in the database, so no direct numeric comparison can be made. The recorded data confirms that any statement about the i9-14901KE performance must remain qualitative. The i5-14400 scores place it within 0.1 percent of the Intel Core i7-13705H (32076) and 0.2 percent of the Intel Core i5-14450HX (32040), while it trails the Intel Core i9-11900 (32226) by 0.3 percent. These deltas indicate that the i5-14400 performs in a tightly packed band of CPUs around the 32000 average score mark, and the i9-14901KE cannot be ranked against those rivals until benchmark data is populated.

# Architecture Differences

Both processors belong to the Intel Core 14th Gen series, use the Raptor Lake architecture, carry the Raptor Lake-R codename, and are built on Intel's 10 nm process node at Intel as the foundry. Both use Intel Socket 1700, support DDR4 and DDR5 memory in dual-channel mode, and provide PCIe Gen 5 with 16 lanes from the CPU. Both support ECC memory. The shared elements stop there.

The i5-14400 contains 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. It has a 65 W TDP and a die size of 215 mm². Its cache hierarchy consists of 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The integrated graphics are UHD Graphics 730. The multiplier is locked.

The i9-14901KE contains 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.80 GHz. It has a 125 W TDP and a die size of 257 mm². The cache layout differs: 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The integrated graphics are UHD Graphics 770. The multiplier is unlocked.

The core count difference is significant. The i5-14400 uses a hybrid arrangement with 10 cores total, while the i9-14901KE uses 8 cores. Both present 16 threads to the operating system, so thread count parity exists despite the core count gap. The i9-14901KE compensates for fewer cores with substantially higher clocks: its base clock is 1.30 GHz higher than the i5-14400, and its boost clock is 1.10 GHz higher. The i9-14901KE also carries more L3 cache (36 MB versus 20 MB) and more L2 per core (2 MB versus 1.25 MB), which reflects its higher tier within the Raptor Lake-R lineup.

The process node is identical at 10 nm, and both chips are produced by Intel. The die size difference (215 mm² for the i5-14400, 257 mm² for the i9-14901KE) suggests the i9-14901KE dedicates more silicon area, consistent with its larger cache and higher clock design. The TDP difference (65 W versus 125 W) indicates the i9-14901KE is designed to draw more power to sustain its higher clock rates, though the database does not record measured power consumption.

The i5-14400 has a release date of 2024-01-07 and an active production status. The i9-14901KE has a release date of 2024-06-30 and also carries an active production status. Both are desktop market segment parts. The i5-14400 has a launch MSRP of $221. The i9-14901KE has no launch MSRP recorded in the database. The i5-14400 part number is SRN3QSRN46, and the i9-14901KE part number is Q49DSRNJC.

# Where Each One Wins

The i5-14400 wins in the only category where the database contains comparative data: measured benchmark results. It holds scores across Cinebench R15, R20, R23, Geekbench, and PassMark, and its average benchmark score of 32115 places it at the 82nd percentile of all CPUs. The i9-14901KE has no recorded benchmark scores, so it cannot claim any measured win in the database. Its position at the 50th percentile with an average score of 0 reflects missing data rather than actual performance.

For workloads that favor many cores at moderate clocks, the i5-14400 offers 10 cores, which is two more than the i9-14901KE. The i5-14400 multicore performance in Cinebench R23 (21315) and PassMark multithread (25080) provides reference points for its throughput in heavily threaded applications. The i9-14901KE, with only 8 cores but a 5.80 GHz boost clock, would rely on higher per-core throughput in lightly threaded workloads. The database does not contain single-core scores for the i9-14901KE, so no direct comparison of single-thread performance is possible.

The i9-14901KE has structural advantages that point to potential wins in single-threaded and lightly threaded scenarios once benchmarks are recorded. Its boost clock of 5.80 GHz is 1.10 GHz higher than the i5-14400 boost clock, and its base clock of 3.80 GHz is 1.30 GHz higher. Higher clocks generally translate to stronger single-thread performance, but the database lacks the measurements to confirm this.

The i9-14901KE also has a larger L3 cache (36 MB versus 20 MB), which can benefit workloads with large working sets that fit within the cache. The larger L2 per core (2 MB versus 1.25 MB) may help latency-sensitive workloads. The i5-14400 counters with more physical cores, which can help in fully parallel workloads that scale beyond 8 threads, though both CPUs present 16 threads.

The unlocked multiplier on the i9-14901KE allows manual overclocking, while the i5-14400 has a locked multiplier. The database does not record overclocked results, so the practical impact remains outside the measured data. The integrated graphics differ: the i9-14901KE uses UHD Graphics 770, while the i5-14400 uses UHD Graphics 730. The database does not record iGPU benchmark scores for either part.
