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

The Verdict

The database records two Intel desktop processors from different design generations. The Intel Core i5-14401TE is a 6-core, 12-thread Raptor Lake part on Socket 1700, while the Intel Core Ultra 7 155HL is a 16-core, 22-thread Meteor Lake part on Socket 1851. Neither part has recorded benchmark scores in the database, and both sit at the 50th percentile against all CPUs. With no measured performance data available, the verdict rests entirely on architectural and specification differences. The Core Ultra 7 155HL offers more cores, more threads, a larger shared L3 cache, a higher boost clock, and a newer process node. The Core i5-14401TE counters with a higher base clock, support for DDR4 memory, ECC memory support, PCIe Gen 5 connectivity, and a larger physical die. Users requiring maximum thread count and newer integrated graphics should select the Core Ultra 7 155HL. Users requiring ECC memory, DDR4 compatibility, or PCIe Gen 5 lanes should select the Core i5-14401TE.

Architecture Differences

The Core i5-14401TE uses Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process node. It employs a monolithic die measuring 215 mm², with 6 cores and 12 threads. The Core Ultra 7 155HL uses Meteor Lake architecture under the Meteor Lake-PS codename, fabricated on a 7 nm process node. It provides 16 cores and 22 threads, indicating a hybrid design with more physical cores than the i5 part.

Cache hierarchies differ substantially. The Core i5-14401TE provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. The Core Ultra 7 155HL provides 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Ultra 7 leads in every cache tier.

Memory support splits the two parts. The Core i5-14401TE supports both DDR4 and DDR5 memory across a dual-channel bus, with ECC memory enabled. The Core Ultra 7 155HL supports DDR5 only, with capacity dependent on the motherboard, also over a dual-channel bus, and the database lists a memory bandwidth figure of 89.6 GB/s for this part. ECC memory is not supported on the Ultra 7.

PCIe connectivity also diverges. The Core i5-14401TE provides PCIe Gen 5 with 16 lanes from the CPU. The Core Ultra 7 155HL provides PCIe Gen 4 with 8 lanes from the CPU. Integrated graphics differ as well: the i5 uses UHD Graphics 730, while the Ultra 7 uses Arc Xe-LPG 128EU. Both processors have locked multipliers, and both are listed as active production parts.

Sockets are incompatible. The Core i5-14401TE mounts on Intel Socket 1700, while the Core Ultra 7 155HL mounts on Intel Socket 1851. The Core Ultra 7 155HL carries a launch MSRP of $438; the Core i5-14401TE has no recorded launch MSRP.

Where Each One Wins

The Core i5-14401TE wins on base clock frequency, starting at 2.00 GHz versus 1.40 GHz on the Ultra 7. For workloads that scale with base clock and lower core counts, the Raptor Lake part has the advantage in the recorded specifications. The i5 also wins on memory flexibility with DDR4 and DDR5 support, whereas the Ultra 7 is restricted to DDR5. ECC memory support is exclusive to the Core i5-14401TE, making it the choice for error-sensitive workloads. PCIe Gen 5 with 16 lanes gives the i5 an edge in available bandwidth and lane count for expansion devices. The 215 mm² die size is larger than the Ultra 7, which has no recorded die size, but the larger die in the i5 reflects its monolithic design.

The Core Ultra 7 155HL wins on core count with 16 cores versus 6, and thread count with 22 threads versus 12. Its boost clock reaches 4.80 GHz versus 4.50 GHz on the i5. The Ultra 7 has larger per-core L1 and L2 caches and a larger shared L3 cache. The 7 nm process node is smaller than the 10 nm node used by the i5, indicating a denser manufacturing process. The Ultra 7 includes a more capable integrated graphics solution in the Arc Xe-LPG 128EU, compared to UHD Graphics 730 on the i5. The Ultra 7 also has a recorded memory bandwidth of 89.6 GB/s, a figure not listed for the i5.
