Intel Core i5-14501TE vs Intel Core Ultra 5 125UL Comparison

Architecture Differences

The Intel Core i5-14501TE and the Intel Core Ultra 5 125UL represent two distinct design philosophies from Intel. The i5-14501TE is built on the Raptor Lake architecture, specifically the Raptor Lake-R refresh, and belongs to the Core 14th Gen series. It uses a 10 nm process node and is fabricated by Intel. The die size is recorded at 215 mm², which is a notable physical detail.

The Core Ultra 5 125UL, on the other hand, uses the Meteor Lake architecture with the Meteor Lake-PS codename. It is part of the Core Ultra Series 1 and is manufactured on a 7 nm process node, also by Intel. The die size for this part is not recorded in the database. This architectural shift represents a move to a newer process technology, which typically allows for improved power efficiency and transistor density, though the database does not provide transistor counts for either chip.

Cache layouts differ significantly between the two. The i5-14501TE has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a shared L3 cache of 24 MB. The Core Ultra 5 125UL has a larger per-core L1 cache at 112 KB, a larger L2 cache at 2 MB per core, but a smaller shared L3 cache at 12 MB. This means the i5-14501TE has double the total L3 cache, which can benefit workloads that rely on larger shared pools of fast memory.

Memory support also diverges. The i5-14501TE supports both DDR4 and DDR5 memory, giving builders flexibility depending on the motherboard. The Core Ultra 5 125UL supports DDR5 only, and the database notes that support depends on the motherboard. Both use a dual-channel memory bus, but the Core Ultra 5 125UL has a recorded memory bandwidth of 89.6 GB/s, while the i5-14501TE does not have a listed bandwidth figure.

PCIe connectivity is another major difference. The i5-14501TE provides PCIe Gen 5 with 16 lanes from the CPU. The Core Ultra 5 125UL uses PCIe Gen 4 with only 8 lanes from the CPU. This makes the i5-14501TE more capable for high-bandwidth expansion cards, such as modern graphics cards or NVMe storage, assuming the rest of the platform supports it.

Integrated graphics differ as well. The i5-14501TE uses UHD Graphics 770, while the Core Ultra 5 125UL uses Arc Xe-LPG 64EU. The database does not provide benchmark scores for either iGPU, so a direct performance comparison is not possible from the recorded data.

ECC memory support is present on the i5-14501TE, which is a feature often sought in workstation or entry-server builds. The Core Ultra 5 125UL does not support ECC memory. This is a functional difference that may steer buyers toward one part or the other depending on their reliability requirements.

Specification Differences

The two processors differ across nearly every core specification. The i5-14501TE has 6 cores and 12 threads. The Core Ultra 5 125UL has 12 cores and 14 threads. The thread count difference is smaller than the core count difference, which suggests the Core Ultra part uses a mix of core types, though the database does not detail the exact core type breakdown.

Base clocks are very different. The i5-14501TE runs at a base clock of 2.20 GHz, while the Core Ultra 5 125UL runs at 1.30 GHz. Boost clocks also favor the i5-14501TE, with a maximum boost of 5.10 GHz compared to 4.30 GHz on the Core Ultra 5 125UL. This gives the i5-14501TE a substantial clock advantage in single-threaded and lightly threaded workloads.

Thermal design power is a major differentiator. The i5-14501TE has a TDP of 45 watts, while the Core Ultra 5 125UL has a TDP of only 15 watts. This puts the Core Ultra part in a much lower power envelope, which is typical for designs aimed at fanless or small-form-factor systems, though the database does not specify the intended cooling solution.

Sockets differ completely. The i5-14501TE uses Intel Socket 1700, while the Core Ultra 5 125UL uses Intel Socket 1851. These are not cross-compatible, so the motherboard choice dictates which CPU can be used.

The release dates are close but not identical. The Core Ultra 5 125UL was released on April 7, 2024, while the i5-14501TE was released on June 30, 2024. Both are listed as Active in production status.

The Core Ultra 5 125UL has a launch MSRP of $309. The i5-14501TE does not have a recorded launch MSRP in the database.

The part numbers are also different: the i5-14501TE is listed as Q49KSRNJN, and the Core Ultra 5 125UL is listed as SRN96.

Neither processor has an unlocked multiplier, so overclocking is not an option on either part according to the recorded data.

Where Each One Wins

Based on the recorded specifications, the i5-14501TE is positioned for workloads that favor high clock speeds and larger shared cache. Its 5.10 GHz boost clock is a strong indicator for single-threaded performance. Applications such as older games, lightly threaded productivity tools, or tasks that depend on low-latency access to a large L3 cache would likely benefit from this part. The 45 watt TDP also suggests it can sustain higher performance under load compared to the 15 watt part, assuming adequate cooling is provided.

The Core Ultra 5 125UL, with its 12 cores and 14 threads, is better suited for heavily threaded workloads where the higher core count can be utilized. Its lower 1.30 GHz base clock and 4.30 GHz boost clock mean it will not match the i5-14501TE in raw single-thread speed, but the additional cores provide more parallel throughput for tasks like video encoding, compilation, or multi-tasking. The 15 watt TDP also makes it a candidate for power-constrained systems where thermal output is a primary concern.

The i5-14501TE has an advantage in platform flexibility due to its support for both DDR4 and DDR5 memory. Builders with existing DDR4 modules can reuse them, while those wanting newer DDR5 can also use it. The Core Ultra 5 125UL is limited to DDR5, which may require a more expensive platform investment.

PCIe Gen 5 support on the i5-14501TE gives it an edge for future-proofing storage or GPU bandwidth. The Core Ultra 5 125UL is limited to PCIe Gen 4, which is still capable but not as advanced. ECC memory support on the i5-14501TE is another point in its favor for reliability-focused builds.

The Core Ultra 5 125UL wins on power efficiency, a key factor for compact or passively cooled systems. Its 15 watt TDP is a third of the i5-14501TE's 45 watt TDP. The newer 7 nm process node also suggests better efficiency per watt, though the database does not provide direct efficiency metrics.

Head-to-Head Benchmarks

The database does not include direct head-to-head benchmark scores for these two processors. The benchmark arrays for both parts are empty, and there are no nearest rival entries recorded. The wins count for each processor is zero. Without measured performance data, a direct comparison of application performance is not possible from the recorded information.

However, the specification data allows for a reasoned comparison. The i5-14501TE has a 0.90 GHz higher base clock and a 0.80 GHz higher boost clock. In single-threaded workloads, this clock advantage is typically decisive, though the database does not quantify the exact performance difference. The i5-14501TE also has double the L3 cache, 24 MB versus 12 MB, which can reduce memory latency in cache-sensitive workloads.

The Core Ultra 5 125UL has a 6 core advantage, which can translate to significantly higher multi-threaded throughput in well-parallelized workloads. The 14 thread count is only 2 threads higher than the i5-14501TE, which is an unusual ratio. This suggests that some cores on the Core Ultra part may be efficiency cores with lower performance per thread, though the database does not provide the core type breakdown.

The Core Ultra 5 125UL has a higher memory bandwidth figure at 89.6 GB/s, while the i5-14501TE does not have a recorded bandwidth value. This could indicate an advantage in memory-intensive tasks, but the lack of a comparison figure limits the analysis.

The process node difference, 7 nm for the Core Ultra part versus 10 nm for the i5-14501TE, suggests the Core Ultra part should have better power efficiency under load. The TDP difference of 30 watts reinforces this, with the Core Ultra part consuming substantially less power at the specified TDP.

The Verdict

The Intel Core i5-14501TE is the choice for builders who prioritize high clock speeds, large shared cache, and platform flexibility. Its 5.10 GHz boost clock and 24 MB L3 cache position it well for single-threaded and lightly threaded workloads. The support for both DDR4 and DDR5 memory, along with PCIe Gen 5 and ECC memory, makes it a versatile desktop part for a wide range of builds. The 45 watt TDP requires more robust cooling than the 15 watt part, but it still fits in the low-power desktop segment.

The Intel Core Ultra 5 125UL is the choice for power-constrained systems where core count matters more than clock speed. Its 12 cores and 14 threads provide greater parallel processing capability, and the 15 watt TDP makes it suitable for compact or passively cooled enclosures. The newer 7 nm process node and 89.6 GB/s memory bandwidth are additional points in its favor. The lack of DDR4 support and ECC memory are limitations that may rule it out for some users.

The socket difference means these two processors are not interchangeable. A buyer must decide on the platform first: Socket 1700 for the i5-14501TE or Socket 1851 for the Core Ultra 5 125UL. The i5-14501TE offers higher clocks and more cache, while the Core Ultra 5 125UL offers more cores and lower power consumption. The recorded data does not include benchmark scores, so the final decision rests on which specifications matter more for the intended use case.
