Intel Core i5-14401TE vs Intel Core Ultra 5 235TA Comparison

Where Each One Wins

The recorded data splits the two processors cleanly by workload philosophy rather than by raw performance dominance. The Intel Core i5-14401TE, built on Raptor Lake Refresh, brings 6 cores and 12 threads with a boost clock of 4.50 GHz. That configuration favors lightly threaded tasks where single-core speed and thread scheduling flexibility matter most. Its 45 W TDP and support for both DDR4 and DDR5 memory make it a flexible choice for systems that do not demand the latest memory standard.

The Intel Core Ultra 5 235TA, by contrast, uses Arrow Lake architecture with 14 cores and 14 threads. There is no hyper-threading here, so each core is a physical thread. The boost clock reaches 5.00 GHz, and the base clock sits at 2.20 GHz. The core count advantage is substantial, 14 versus 6, which points to multi-core workloads such as compilation, rendering, or heavy multitasking. The Ultra 5 also supports only DDR5 memory, with a memory bandwidth of 102.4 GB/s, indicating a platform designed for higher throughput rather than legacy compatibility.

Where the i5-14401TE wins is in scenarios that prize lower power draw and simpler platform integration. The 45 W TDP versus 65 W TDP means less heat and potentially smaller cooling requirements, though the database does not quantify cooling performance. The i5 also supports ECC memory, which the Ultra 5 does not, making the older chip more suitable for error-sensitive compute environments such as NAS builds or entry-level servers.

The Ultra 5 235TA wins where core count and memory bandwidth translate directly into throughput. With 14 cores and a higher boost clock, it should outperform in parallel workloads. The 24 MB shared L3 cache versus 20 MB also provides a larger working set for data reuse. The PCIe Gen 5 implementation on the Ultra 5 offers 20 lanes (CPU only) versus 16 lanes on the i5, which benefits systems with multiple high-bandwidth expansion cards or NVMe drives.

The integrated graphics differ as well. The i5-14401TE uses UHD Graphics 730, a straightforward display output solution. The Ultra 5 uses Arc Xe-LPG Graphics 24EU, which suggests better media and compute capabilities in the iGPU, though the database does not provide benchmark scores to confirm. For systems without a discrete GPU, the Ultra 5 likely provides a better experience for light graphics work, while the i5 covers basic display needs.

Architecture Differences

The two processors come from different foundries and process nodes. The i5-14401TE uses Intel's 10 nm process with a die size of 215 mm². The Ultra 5 235TA uses TSMC's 3 nm process with a die size of 243 mm² and a transistor count of 17,800 million. The smaller process node and higher transistor count indicate a more modern design with denser logic and potentially better power efficiency per transistor, though the Ultra 5's higher TDP suggests the extra cores draw more total power.

The core layouts are fundamentally different. The i5-14401TE has 6 cores and 12 threads, meaning each core supports two threads via hyper-threading. The Ultra 5 has 14 cores and 14 threads, with no hyper-threading, so each core is independent. The cache hierarchy reflects this: the i5 has 80 KB of L1 per core and 1.25 MB of L2 per core, while the Ultra 5 has 192 KB of L1 per core and 3 MB of L2 per core. The L3 cache goes from 20 MB shared on the i5 to 24 MB shared on the Ultra 5. The larger per-core caches on the Ultra 5 suggest a design aimed at feeding more execution units per core.

Memory support is a major divider. The i5-14401TE accepts both DDR4 and DDR5, giving builders the option to reuse older memory. The Ultra 5 supports only DDR5, and its memory bandwidth is specified at 102.4 GB/s, a figure not listed for the i5. The i5 also has ECC memory support, which the Ultra 5 lacks. That makes the i5 a candidate for reliability-focused builds, while the Ultra 5 targets pure performance with higher memory throughput.

Socket compatibility also separates them. The i5-14401TE uses Intel Socket 1700, while the Ultra 5 uses Intel Socket 1851. These are not interchangeable, so platform choice locks in the processor generation. The release dates confirm the generational gap: the i5 came out on 2024-06-30, and the Ultra 5 on 2025-07-28. The Ultra 5 has a launch MSRP of $269, while the i5 has no listed launch price.

The PCIe capabilities differ: the i5 provides Gen 5 with 16 lanes (CPU only), while the Ultra 5 provides Gen 5 with 20 lanes (CPU only). For storage or GPU expansion, the Ultra 5 offers more direct CPU-attached bandwidth. Both processors have locked multipliers, meaning no overclocking via multiplier adjustment.

Head-to-Head Benchmarks

The head-to-head benchmark array is empty, and both processors show zero wins in direct comparisons. The database records no individual benchmark scores for either unit, and the average benchmark score is 0 for both. The percentile versus all CPUs is 50 for each, indicating median positioning in the overall distribution, but this is not a direct comparison metric.

Given the lack of recorded benchmark numbers, the analysis must rely on architectural specifications to project relative performance. The Ultra 5 235TA has a 0.50 GHz higher boost clock (5.00 versus 4.50) and a 0.20 GHz higher base clock (2.20 versus 2.00). The core count difference is stark: 14 physical cores versus 6 physical cores with hyper-threading. In multi-threaded workloads, the Ultra 5 should deliver significantly higher throughput, though the exact margin cannot be quantified from the data.

The i5-14401TE's hyper-threading gives it 12 logical processors from 6 physical cores, which helps in workloads that scale with thread count but do not require fully independent cores. However, the Ultra 5's 14 physical cores likely outperform the i5's 12 threads in most parallel scenarios, given the higher clock speeds and larger caches.

Single-threaded performance is harder to project. The Ultra 5's higher boost clock suggests an advantage in bursty, single-core tasks, but the i5's Raptor Lake architecture is known for strong single-core performance. The database does not provide specific scores, so a definitive statement is not possible.

The memory bandwidth difference is explicit: the Ultra 5 has 102.4 GB/s, while the i5 has no listed figure. For memory-intensive workloads, the Ultra 5 likely has a clear edge. The L3 cache difference (24 MB versus 20 MB) is modest, but the per-core L2 cache difference (3 MB versus 1.25 MB) is more substantial, favoring the Ultra 5 for workloads that fit in L2.

The integrated graphics cannot be compared numerically, as no iGPU benchmarks exist in the data. The Ultra 5's Arc Xe-LPG Graphics 24EU is a newer architecture than the UHD Graphics 730, but without scores, any performance claim is speculative.

The Verdict

The data points to a clear use-case split. The Intel Core i5-14401TE suits builds where power efficiency, ECC memory support, and DDR4 compatibility are priorities. Its 45 W TDP and dual memory support make it a practical choice for always-on systems or those with legacy memory. The 6-core, 12-thread configuration with a 4.50 GHz boost clock handles everyday desktop tasks, light productivity, and single-threaded applications without excess power draw.

The Intel Core Ultra 5 235TA is the stronger choice for multi-core throughput and modern platform features. Its 14 cores, 5.00 GHz boost clock, 102.4 GB/s memory bandwidth, and 20 PCIe Gen 5 lanes indicate a processor aimed at demanding parallel workloads. The 3 nm TSMC process and 17,800 million transistors represent a more advanced design, though the higher 65 W TDP reflects the additional cores.

For users who need ECC memory, the i5-14401TE is the only option between the two. For users who need maximum core count and memory bandwidth, the Ultra 5 235TA is the clear pick. The lack of direct benchmark scores means the decision rests on specifications. The Ultra 5's architectural advantages in core count, cache size, and memory bandwidth make it the likely winner in most compute-heavy scenarios. The i5-14401TE wins on platform flexibility and power efficiency.

Neither processor has an unlocked multiplier, so overclocking is not a differentiator. The sockets are different, so upgrading from one to the other requires a motherboard change. The release dates, one year apart, show the Ultra 5 as the newer design, and the launch MSRP of $269 for the Ultra 5 provides a reference point, though pricing comparisons are not part of this analysis.
