Intel Core i5-14401E vs Intel Core Ultra 5 245 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive outcome: the Intel Core Ultra 5 245 wins all six recorded head-to-head comparisons against the Intel Core i5-14401E. The results are consistent across every Cinebench iteration, with the Core Ultra 5 245 taking both single-core and multi-core tests without exception.

In Cinebench R15, the Core Ultra 5 245 scores 3318 in the multi-core test versus 1830 for the i5-14401E, a 44.8% advantage. The single-core test shows a similar gap: 468 versus 258, a 44.9% lead. These margins hold steady across the newer Cinebench versions. In R20, the Core Ultra 5 245 posts 13828 multi-core and 1952 single-core, while the i5-14401E manages 7627 and 1076 respectively. The delta remains at 44.8% and 44.9%.

Cinebench R23 confirms the pattern. The Core Ultra 5 245 reaches 32924 multi-core and 4648 single-core. The i5-14401E scores 18161 and 2564. Again, the delta is 44.8% in both tests. The consistency of these percentage differences across all six benchmarks indicates a uniform performance advantage that scales with workload intensity rather than a test-specific quirk.

The average benchmark score in the database places the Core Ultra 5 245 at 48995, while the i5-14401E averages 5253. This gap is substantial, but the comparison is nuanced because the i5-14401E's average is drawn from a different benchmark set. The Core Ultra 5 245 also carries a 90th percentile ranking versus all CPUs, while the i5-14401E sits at the 60th percentile. The nearest rivals for each chip further illustrate the separation: the Core Ultra 5 245 trades within 0.5% of the AMD Ryzen 9 7900 and within 0.8% of the Intel Core i5-14600K, while the i5-14401E sits within 0.8% of the Intel Core i5-13400T.

Architecture Differences

The two processors come from different architectural lineages. The Intel Core i5-14401E is built on Raptor Lake, specifically the Raptor Lake-R refresh, and belongs to the Core 14th Gen series. The Intel Core Ultra 5 245 uses Arrow Lake, specifically Arrow Lake-S, and belongs to the Core Ultra Series 2. The generation fields confirm this split: the i5-14401E is a Raptor Lake Refresh part, while the Core Ultra 5 245 is an Arrow Lake part.

Process technology diverges sharply. The i5-14401E uses a 10 nm node fabricated by Intel. The Core Ultra 5 245 uses a 3 nm node fabricated by TSMC. The transistor count reflects this: the Core Ultra 5 245 integrates 17,800 million transistors on a 243 mm² die, while the i5-14401E's die size is 215 mm² with no transistor count recorded.

Cache arrangements differ in both capacity and organization. The i5-14401E provides 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The Core Ultra 5 245 offers 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The per-core L2 difference is particularly notable, with the Core Ultra 5 245 providing more than double the L2 cache per core.

Memory support also separates the two. The i5-14401E supports both DDR4 and DDR5 memory in a dual-channel configuration. The Core Ultra 5 245 supports DDR5 only, also dual-channel, but with a recorded memory bandwidth of 102.4 GB/s. The i5-14401E has no memory bandwidth figure in the database.

PCIe connectivity differs as well. The i5-14401E provides Gen 5 with 16 CPU lanes. The Core Ultra 5 245 provides Gen 5 with 20 CPU lanes. Integrated graphics also differ: the i5-14401E uses UHD Graphics 730, while the Core Ultra 5 245 uses Arc Xe-LPG Graphics 64EU.

Sockets are incompatible. The i5-14401E uses Intel Socket 1700, while the Core Ultra 5 245 uses Intel Socket 1851. Both processors are locked, with multiplier unlocked set to false, and both target the desktop market segment.

The Verdict

The recorded data points to a clear performance hierarchy. The Intel Core Ultra 5 245 wins every benchmark in the head-to-head set, with consistent 44.8% to 44.9% margins across all six Cinebench tests. The multi-core advantage is substantial, but the single-core advantage is equally pronounced, indicating that the Core Ultra 5 245 does not rely solely on its higher core count.

The i5-14401E's 6 cores and 12 threads place it at a structural disadvantage against the Core Ultra 5 245's 14 cores and 14 threads. The Core Ultra 5 245 also benefits from a newer architecture, a smaller process node, larger caches, and a higher boost clock. The 90th percentile ranking versus all CPUs for the Core Ultra 5 245, compared to the 60th percentile for the i5-14401E, reinforces the gap.

The i5-14401E's nearest rivals cluster around the Intel Core i7-11700B and Intel Core i9-10850K, with score differences of 0.2%. The Core Ultra 5 245's nearest rivals include the AMD Ryzen 9 7900 and the Intel Core i5-14600K. This places the two processors in different competitive tiers. The i5-14401E competes with older high-end parts, while the Core Ultra 5 245 sits alongside current-generation high-performance desktop chips.

Where Each One Wins

The Intel Core Ultra 5 245 wins across every recorded benchmark category. Multi-core workloads such as Cinebench R23 multi-core show a 32924 score versus 18161, a 44.8% lead. Single-core workloads show a similar pattern, with the Core Ultra 5 245 scoring 4648 versus 2564 in Cinebench R23 single-core, a 44.8% lead. The PassMark suite, recorded only for the Core Ultra 5 245, adds further data points: multi-thread score of 38706, single-thread score of 4394, integer math at 91187, floating point math at 120548, and physics at 2569. These figures are not available for the i5-14401E in the database, so direct comparison is not possible.

For the i5-14401E, no benchmark wins are recorded. The head-to-head data records 0 wins for the i5-14401E and 6 wins for the Core Ultra 5 245. The i5-14401E does retain relevance in its own competitive tier, sitting within 0.8% of the Intel Core i5-13400T and within 0.2% of the Intel Core i9-10850K. Users constrained to the Intel Socket 1700 platform, or those requiring DDR4 memory support, would find the i5-14401E the only option of the two. The Core Ultra 5 245, by contrast, requires DDR5 and the newer Socket 1851.

The data suggests the Core Ultra 5 245 is the stronger choice for any workload that benefits from raw compute throughput, whether single-threaded responsiveness or heavily parallel rendering tasks. The i5-14401E offers a lower core count, smaller caches, and a slower boost clock, but it does support DDR4, which may matter for platform compatibility. The Core Ultra 5 245's launch MSRP is $270, while the i5-14401E has no recorded launch price.
