Intel Core i5-14401TE vs Intel Core Ultra 5 135UL Comparison

The Intel Core i5-14401TE and the Intel Core Ultra 5 135UL are two desktop processors from Intel’s 2024 lineup, but they serve very different design philosophies. The i5-14401TE is a Raptor Lake Refresh part with a traditional high-clock P-core layout, while the Core Ultra 5 135UL is a Meteor Lake-PS chip built around a more power-efficient hybrid architecture. The recorded data shows no direct head-to-head benchmark scores for these two processors, and neither has an average benchmark score in the database. Both sit at the 50th percentile among all CPUs, indicating a mid-pack standing. The analysis below relies strictly on the specification and architectural differences captured in the database, along with the limited rivalry data available.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the Intel Core i5-14401TE versus the Intel Core Ultra 5 135UL. The recorded data lists zero wins for either processor in direct competition, and the average benchmark score for both is zero. This absence of measured performance data means the comparison must derive from the architectural and specification fields provided.

What the data does reveal is a stark contrast in core counts and clock speeds. The i5-14401TE uses 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The Core Ultra 5 135UL uses 12 cores and 14 threads, but its base clock is lower at 1.60 GHz and its boost clock is 4.40 GHz. The i5-14401TE has a 0.10 GHz advantage in boost clock, while the Core Ultra 5 135UL has double the core count and two additional threads. However, the i5-14401TE’s higher thermal design power (TDP) of 45 watts versus 15 watts for the Core Ultra 5 135UL suggests the former is designed to sustain higher clocks under load, whereas the latter prioritizes energy efficiency.

The cache hierarchy also differs significantly. The i5-14401TE has 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 5 135UL has 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. The Core Ultra 5 135UL’s larger per-core L1 and L2 caches could benefit latency-sensitive workloads, but the i5-14401TE’s larger shared L3 cache (20 MB versus 12 MB) gives it an advantage in scenarios where data is reused across cores.

Memory support is another differentiator. The i5-14401TE supports both DDR4 and DDR5, while the Core Ultra 5 135UL supports only DDR5, with the database noting that the memory type depends on the motherboard. The Core Ultra 5 135UL also has a recorded memory bandwidth of 89.6 GB/s, whereas the i5-14401TE has no memory bandwidth figure listed. Both use a dual-channel memory bus.

Where Each One Wins

The Intel Core i5-14401TE wins on raw clock speed. Its 4.50 GHz boost clock is the highest among the two, and its 2.00 GHz base clock is also higher than the Core Ultra 5 135UL’s 1.60 GHz base. For workloads that depend on single-thread performance, such as lightly threaded applications or tasks with strict latency requirements, the i5-14401TE’s higher boost clock should provide an edge. The 45-watt TDP further indicates the i5-14401TE is built to sustain higher performance levels, making it suitable for desktop systems where power draw is less of a constraint.

The Core Ultra 5 135UL wins on core count and efficiency. With 12 cores and 14 threads, it offers twice the physical cores of the i5-14401TE. This gives it a clear advantage in multi-threaded workloads such as video rendering, compilation, or scientific computing, provided the software can utilize many threads. The 15-watt TDP is one-third of the i5-14401TE’s, making the Core Ultra 5 135UL far more energy-efficient. Its larger L1 (112 KB per core) and L2 (2 MB per core) caches could also improve performance in workloads that repeatedly access the same data.

The Core Ultra 5 135UL also has a higher memory bandwidth figure of 89.6 GB/s, which is not available for the i5-14401TE in the database. This suggests the Core Ultra 5 135UL may move data more effectively in memory-intensive tasks. Additionally, the Core Ultra 5 135UL uses a 7 nm process node compared to the i5-14401TE’s 10 nm node, which typically allows for better power efficiency per transistor. The i5-14401TE’s die size is recorded as 215 mm², while the Core Ultra 5 135UL’s die size is not listed.

The integrated graphics differ as well. The i5-14401TE uses UHD Graphics 730, while the Core Ultra 5 135UL uses Arc Xe-LPG 64EU. The Arc Xe-LPG architecture is newer and generally more capable, but the database does not provide performance scores for either GPU. The Core Ultra 5 135UL also supports PCIe Gen 4 with 8 lanes (CPU only), whereas the i5-14401TE supports PCIe Gen 5 with 16 lanes (CPU only). The i5-14401TE’s PCIe Gen 5 support doubles the lanes and offers higher bandwidth for compatible devices like NVMe SSDs or GPUs.

Architecture Differences

The Intel Core i5-14401TE is based on Raptor Lake architecture, specifically Raptor Lake-R, and belongs to the Core 14th Gen series. It uses a 10 nm process node built by Intel. The Core Ultra 5 135UL is based on Meteor Lake architecture, specifically Meteor Lake-PS, and belongs to the Core Ultra Series 1. It uses a 7 nm process node, also built by Intel. The process node difference is significant: the 7 nm node is smaller and typically offers better transistor density and power efficiency.

The cache architectures differ in size and organization. The i5-14401TE has 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 5 135UL has 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The Core Ultra 5 135UL’s larger per-core caches suggest a design focused on reducing latency for individual cores, while the i5-14401TE’s larger shared L3 cache is better suited for workloads with high data sharing between cores.

The integrated graphics are also architecturally different. The i5-14401TE uses UHD Graphics 730, which is part of the Raptor Lake integrated GPU lineup. The Core Ultra 5 135UL uses Arc Xe-LPG 64EU, which is a newer GPU architecture with more execution units (64 versus the unspecified count for UHD Graphics 730). The Core Ultra 5 135UL also supports PCIe Gen 4, while the i5-14401TE supports PCIe Gen 5. The i5-14401TE has ECC memory support, which is absent on the Core Ultra 5 135UL.

The Verdict

The data indicates a clear split in intended use cases. The Intel Core i5-14401TE is the higher-clock, single-thread-focused processor. Its 4.50 GHz boost clock, 20 MB of L3 cache, and support for DDR4 and DDR5 make it a flexible option for desktop systems where legacy memory compatibility or high-frequency single-core performance is required. The 45-watt TDP shows it can draw more power, which typically allows sustained high clocks, but it also means higher energy consumption. The PCIe Gen 5 support with 16 lanes gives it an advantage for high-bandwidth peripherals, and ECC memory support makes it suitable for workstation-class reliability tasks.

The Intel Core Ultra 5 135UL is the efficiency and multi-core champion. Its 12 cores and 14 threads, combined with a 15-watt TDP, make it far more energy-efficient while offering parallel processing capabilities that the i5-14401TE cannot match. The 7 nm process node and larger per-core L1 and L2 caches indicate a design optimized for power-per-watt and latency reduction. The 89.6 GB/s memory bandwidth, though not directly comparable to the i5-14401TE due to missing data, is a recorded advantage. The Arc Xe-LPG 64EU integrated graphics are newer and likely more capable, and the lower TDP makes it easier to cool in compact systems.

For users who prioritize maximum clock speed, ECC support, PCIe Gen 5 connectivity, or DDR4 compatibility, the Intel Core i5-14401TE is the logical choice. For users who need many cores for multi-threaded workloads, value energy efficiency, or want a newer integrated GPU, the Intel Core Ultra 5 135UL is the better fit. The database shows no direct performance measurements, so the decision rests on these recorded architectural and specification differences. The i5-14401TE’s higher clocks and larger shared cache suit single-threaded and latency-sensitive tasks, while the Core Ultra 5 135UL’s core count and low TDP suit parallel and power-constrained environments. Neither processor has a confirmed performance advantage in the absence of benchmark scores, but the specification data points to distinct strengths for each.
