Intel Core i5-14401TE vs Intel Core Ultra 7 155UL Comparison

Head-to-Head Benchmarks

The database records no direct benchmark scores for either the Intel Core i5-14401TE or the Intel Core Ultra 7 155UL. Both processors have an average benchmark score of zero, and both sit at the 50th percentile against all CPUs in the database. The head-to-head benchmark table is empty, which means there are no measured performance comparisons available for these two desktop parts.

What the data does show is the structural difference in core arrangements. The Core i5-14401TE has 6 cores and 12 threads, while the Core Ultra 7 155UL has 12 cores and 14 threads. The higher thread count on the Ultra 7 comes from a hybrid design, but the recorded data does not break down performance cores versus efficiency cores. The Core Ultra 7 155UL also boosts to 4.80 GHz, which is 0.30 GHz higher than the Core i5-14401TE's 4.50 GHz boost. Base clocks favor the Core i5, at 2.00 GHz versus 1.70 GHz.

Without actual benchmark scores, the wins cannot be quantified. The Core i5-14401TE uses a Raptor Lake architecture with a 10 nm process node. The Core Ultra 7 155UL uses Meteor Lake on a 7 nm node. That process difference suggests the Ultra 7 should have an efficiency advantage, but the database contains no measured power or performance data to confirm it. The Core Ultra 7 has a 15 W TDP, while the Core i5 is rated at 45 W. That is a large thermal gap, and it indicates the Ultra 7 is designed for lower sustained power draw, but again, no benchmark results exist to translate that into performance numbers.

The absence of benchmark data means the head-to-head comparison rests entirely on specifications. The Core Ultra 7 155UL has double the core count, a higher boost clock, and a smaller process node. The Core i5-14401TE has a higher base clock and supports ECC memory. Neither part has a measured performance score in the database, so any claim of a win in a specific workload cannot be supported by the recorded data.

The Verdict

The recorded data points to the Core Ultra 7 155UL as the more capable multi-threaded part, based on its 12 cores and 14 threads versus the Core i5-14401TE's 6 cores and 12 threads. The Ultra 7 also has a higher boost clock, a smaller process node, and a much lower TDP. The Core i5-14401TE counters with a higher base clock, ECC memory support, PCIe Gen 5 with 16 lanes, and a larger shared L3 cache of 20 MB versus 12 MB.

For a builder prioritizing raw core count and efficiency, the Core Ultra 7 155UL is the clear choice from the specification sheet. Its 15 W TDP makes it suitable for low-power systems, and the 7 nm node suggests better thermal behavior. The Core i5-14401TE, with its 45 W TDP and 10 nm node, is positioned for more traditional desktop workloads where ECC memory and PCIe Gen 5 connectivity matter.

However, the database contains no benchmark scores for either processor. The average benchmark score for both is zero, and the percentile ranking for both is 50. This means the verdict rests on specifications alone, and the actual performance gap cannot be measured from the recorded data.

The Core i5-14401TE uses the Intel Socket 1700, while the Core Ultra 7 155UL uses the newer Intel Socket 1851. This means they are not interchangeable in a motherboard. The Core i5 supports both DDR4 and DDR5 memory, while the Core Ultra 7 supports DDR5 only, with the specific configuration depending on the motherboard.

Architecture Differences

The two processors come from different Intel architectures. The Core i5-14401TE is based on Raptor Lake, specifically the Raptor Lake-R refresh, and belongs to the Core 14th Gen series. The Core Ultra 7 155UL is based on Meteor Lake, specifically the Meteor Lake-PS variant, and belongs to the Core Ultra Series 1.

The process nodes differ significantly. The Core i5-14401TE uses a 10 nm process, while the Core Ultra 7 155UL uses a 7 nm process. Both are fabricated by Intel. The die size for the Core i5 is listed at 215 mm², while the die size for the Core Ultra 7 is not recorded in the database.

Cache architecture differs as well. The Core i5 has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The Core Ultra 7 has 112 KB of L1 cache per core and 2 MB of L2 cache per core. The shared L3 cache is larger on the Core i5 at 20 MB, compared to 12 MB on the Core Ultra 7.

Memory bandwidth is only listed for the Core Ultra 7, at 89.6 GB/s. The Core i5 does not have a recorded memory bandwidth figure. The Core Ultra 7 also has a narrower PCIe implementation, with Gen 4 and 8 lanes from the CPU, while the Core i5 has Gen 5 with 16 lanes.

The integrated graphics are different as well. The Core i5 uses UHD Graphics 730, while the Core Ultra 7 uses Arc Xe-LPG 64EU. The Core Ultra 7's graphics solution is newer and likely more capable, but the database does not include graphics benchmark scores.

ECC memory support is exclusive to the Core i5-14401TE. The Core Ultra 7 155UL does not support ECC memory. This is a meaningful difference for users running memory-intensive workloads that benefit from error correction.

Where Each One Wins

The Core Ultra 7 155UL wins on core count, thread count, boost clock, process node, and TDP. Its 12 cores and 14 threads give it a structural advantage in multi-threaded workloads, assuming the software can utilize the additional threads. The 15 W TDP makes it the lower-power option by a wide margin, which matters for systems with strict thermal or power budgets. The 7 nm process node supports that efficiency profile.

The Core Ultra 7 also has a higher boost clock at 4.80 GHz, which should help in lightly threaded tasks that rely on single-core speed. It has a larger L1 and L2 cache per core, which can reduce latency for frequently accessed data. Its memory bandwidth is recorded at 89.6 GB/s, while the Core i5 has no recorded bandwidth figure.

The Core i5-14401TE wins on base clock, L3 cache size, memory flexibility, ECC support, and PCIe connectivity. Its 2.00 GHz base clock is higher than the Ultra 7's 1.70 GHz. The 20 MB shared L3 cache is substantially larger than the 12 MB on the Ultra 7, which can benefit workloads with large working sets that fit in cache.

The Core i5 supports both DDR4 and DDR5 memory, giving users more options when selecting a motherboard and RAM. ECC memory support is a differentiator for stability-sensitive applications. The PCIe Gen 5 interface with 16 lanes provides more bandwidth for expansion cards, storage, and other peripherals compared to the Gen 4, 8-lane implementation on the Ultra 7.

The Core i5 also has a listed die size of 215 mm², while the Ultra 7's die size is not recorded. The Core i5 uses the Intel Socket 1700 platform, which is more established, while the Ultra 7 uses the newer Socket 1851.

For a use-case split, the Core Ultra 7 155UL suits compact, low-power desktop builds where multi-threaded performance per watt is the priority. The Core i5-14401TE suits traditional desktop towers where power draw is less constrained, and where ECC memory, DDR4 compatibility, and PCIe Gen 5 bandwidth are requirements.
