Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors. The i7-14701E has a comprehensive set of recorded benchmark scores, while the Ultra 5 135UL has no recorded benchmark scores in the database. This means a direct comparison must rely on the performance profile of the i7-14701E and its percentile positioning.

The i7-14701E achieves an average benchmark score of 33,206 across all recorded tests. This places it in the 83rd percentile of all CPUs. Its nearest rivals include the AMD Ryzen 9 PRO 6950H with an average score of 33,201 (a delta of 0%), the AMD Ryzen 5 8645HS with 33,244 (a delta of -0.1%), the AMD Ryzen 7 7745HX with 33,091 (a delta of 0.3%), and the Intel Core i7-13650HX with 33,089 (a delta of 0.4%).

In Cinebench tests, the i7-14701E scores 2,237 in R15 multicore, 315 in R15 single-core, 9,321 in R20 multicore, 1,315 in R20 single-core, 22,195 in R23 multicore, and 3,133 in R23 single-core. These scores indicate strong multithreaded performance relative to its single-thread results.

The PassMark suite shows varied results. The i7-14701E scores 282,939 in data compression, 14,862 in data encryption, 18,528 in extended instructions, 176 in find prime numbers, 61,873 in floating point math, 81,325 in integer math, 26,112 in multithread, 2,399 in physics, 29,158 in random string sorting, and 4,305 in single-thread tests.

The absence of benchmark data for the Ultra 5 135UL means the database cannot confirm a performance delta between these two specific processors. The i7-14701E's 83rd percentile ranking versus the Ultra 5 135UL's 50th percentile ranking suggests a likely performance gap, but without direct measurements, the magnitude remains speculative.

The i7-14701E's boost clock of 5.40 GHz is substantially higher than the Ultra 5 135UL's 4.40 GHz. For single-threaded workloads, which often depend heavily on clock speed, this difference likely favors the i7-14701E. The i7-14701E also has more threads (16 versus 14), which could benefit heavily threaded workloads.

The Verdict

The recorded data shows a clear performance hierarchy. The Intel Core i7-14701E ranks in the 83rd percentile of all CPUs with an average benchmark score of 33,206. The Intel Core Ultra 5 135UL ranks in the 50th percentile with no recorded benchmark scores. The i7-14701E is positioned for desktop users who prioritize computational performance, as indicated by its high Cinebench and PassMark scores.

The Ultra 5 135UL, with its 15 watt TDP, is designed for efficiency rather than raw performance. Its 12 cores and 14 threads provide parallel processing capability, but its lower clock speeds (1.60 GHz base, 4.40 GHz boost) and smaller L3 cache (12 MB versus 33 MB) suggest it targets power-constrained environments.

For workloads that demand high single-thread performance, the i7-14701E's 5.40 GHz boost clock is a significant advantage. Its 16 threads and 33 MB L3 cache also position it well for multithreaded applications like rendering or compilation. The i7-14701E's support for ECC memory adds reliability for data-sensitive tasks.

The Ultra 5 135UL uses a newer 7 nm process node and includes Arc Xe-LPG 64EU integrated graphics, which may offer better integrated graphics performance than the UHD Graphics 770 in the i7-14701E. Its 89.6 GB/s memory bandwidth is recorded, while the i7-14701E has no such figure.

Neither processor has an unlocked multiplier, so overclocking is not a differentiator. The i7-14701E uses PCIe Gen 5 with 16 lanes, while the Ultra 5 135UL uses PCIe Gen 4 with 8 lanes. This favors the i7-14701E for high-bandwidth peripherals like modern GPUs or NVMe storage.

Where Each One Wins

The i7-14701E wins in scenarios that require high computational throughput. Its recorded benchmark scores show strength in Cinebench R23 multicore (22,195) and single-core (3,133), which translates to rendering, video encoding, and general productivity. The PassMark multithread score of 26,112 and integer math score of 81,325 further indicate capability in CPU-intensive applications. The 5.40 GHz boost clock gives it an edge in single-threaded tasks where clock speed dominates, such as legacy software or lightly threaded games.

The i7-14701E also wins on memory flexibility with support for both DDR4 and DDR5. Its PCIe Gen 5 with 16 lanes supports faster storage and graphics interconnects. ECC memory support makes it suitable for error-sensitive workloads like data processing or scientific computing.

The Ultra 5 135UL wins in power efficiency. Its 15 watt TDP is dramatically lower than the i7-14701E's 65 watts. This makes it suitable for passively cooled systems, small form factor desktops, or always-on machines where heat and power draw matter. The 7 nm process node suggests better power efficiency per transistor, though the database does not record efficiency metrics.

The Ultra 5 135UL also wins on core count with 12 cores versus 8, which could benefit workloads that scale across many cores but do not require high clock speeds. Its larger L1 cache per core (112 KB versus 80 KB) may help certain workloads with frequent small data accesses. The Arc Xe-LPG 64EU integrated graphics likely provides better integrated graphics performance than UHD Graphics 770, though no direct comparison data exists.

The Ultra 5 135UL has a recorded memory bandwidth of 89.6 GB/s, which is a specification advantage over the i7-14701E's unrecorded figure. This could matter for memory-bound workloads, though the i7-14701E's larger L3 cache may compensate in some cases.

For users who prioritize raw performance, the i7-14701E is the clear choice based on its percentile ranking and benchmark scores. For users who prioritize low power consumption and integrated graphics capability, the Ultra 5 135UL offers a distinct profile. The data does not support a single universal winner; the choice depends on workload and system constraints.
