Intel Core i5-14401TE vs Intel Core Ultra 9 285K Comparison

The Verdict

The data positions these two processors at opposite ends of Intel's desktop spectrum. The Intel Core i5-14401TE is a 6-core, 12-thread Raptor Lake part with a 45 W TDP, designed for efficiency and modest workloads. The Intel Core Ultra 9 285K is a 24-core, 24-thread Arrow Lake flagship with a 125 W TDP, a 3 nm process node, and a 96th percentile ranking across all CPUs. The verdict is straightforward: the Core Ultra 9 285K dominates every recorded benchmark category, delivering roughly 6.5 times the average benchmark score (83,807 versus 0 for the i5-14401TE, which has no recorded benchmark scores in the database). The i5-14401TE is for builders prioritizing low power consumption and a compact platform, while the 285K is for users who need maximum multi-threaded throughput and do not constrain power draw.

The Core Ultra 9 285K also commands a 46th percentile advantage over the i5-14401TE (96 versus 50), placing it among the top 4% of all CPUs in the database. The i5-14401TE sits exactly at the median, meaning half of all recorded CPUs outperform it. No benchmark scores exist for the i5-14401TE, so the comparison relies entirely on the 285K's recorded results and architectural specifications. The 285K's nearest rivals include the Intel Core Ultra 9 290K Plus (0.2% ahead), AMD EPYC 4584PX (0.9% behind), AMD EPYC 9135 (1% behind), and AMD EPYC 7F72 (1.5% ahead), all within a tight 2.5% band. This confirms the 285K is a high-end contender, not a mid-pack part.

Where Each One Wins

The Core Ultra 9 285K wins in every measurable performance domain. In Cinebench R23 multi-core, it scores 42,522; in Geekbench multi-core, 26,702; in PassMark multi-thread, 67,260; and in PassMark integer math, 172,379. These are production-grade numbers for rendering, compilation, and scientific simulation. The i5-14401TE has no recorded scores, so its wins are structural rather than benchmark-based: it uses a 45 W TDP versus 125 W, supports DDR4 in addition to DDR5, and fits the Intel Socket 1700 platform, which is older and more widely deployed. The i5 also uses the 10 nm process node, whereas the 285K uses the 3 nm TSMC node, meaning the i5 is a more conservative, power-lean design.

The 285K's single-thread performance also leads decisively. Its Cinebench R23 single-core score is 2,377, its Geekbench single-core is 2,870, and its PassMark single-thread is 5,087. These numbers indicate strong per-core efficiency despite the higher core count. The i5-14401TE's boost clock is 4.50 GHz, while the 285K boosts to 5.70 GHz, a 1.20 GHz advantage that explains much of the single-core gap. The 285K also has double the L3 cache (36 MB versus 20 MB) and larger per-core L1 (192 KB versus 80 KB) and L2 (3 MB versus 1.25 MB) caches.

Architecture Differences

The i5-14401TE uses Raptor Lake architecture (Raptor Lake-R codename) on a 10 nm Intel process, with 6 cores and 12 threads. Its die size is 215 mm². The Core Ultra 9 285K uses Arrow Lake architecture (Arrow Lake-S codename) on a 3 nm TSMC process, with 24 cores and 24 threads. Its die size is 243 mm², and it packs 17,800 million transistors. The transistor count for the i5 is not recorded in the database. The 285K's process node is three generations ahead in density, and the foundry is TSMC rather than Intel.

The cache hierarchy differs substantially. The i5 has 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. The 285K has 192 KB L1 per core, 3 MB L2 per core, and 36 MB shared L3. Total L3 for both is not specified separately, but the shared figures are recorded. The 285K's L3 is 80% larger, and its per-core L2 is 140% larger. The 285K also supports only DDR5 memory with a recorded bandwidth of 102.4 GB/s, while the i5 supports both DDR4 and DDR5 with dual-channel memory and no recorded bandwidth figure. Both support ECC memory.

The 285K features an Arc Xe-LPG Graphics 64EU integrated GPU, while the i5 uses UHD Graphics 730. The 285K has 20 PCIe Gen 5 lanes (CPU only), versus 16 for the i5. The 285K's multiplier is unlocked, enabling overclocking; the i5's is locked. The 285K's launch MSRP is $589, stated once here. The i5 has no recorded launch MSRP. Release dates differ: the i5 launched on 2024-06-30, and the 285K on 2024-10-23, roughly four months later.
