Intel Core i5-14501E vs Intel Core Ultra 5 250KF Plus Comparison

Head-to-Head Benchmarks

The Core Ultra 5 250KF Plus and the Core i5-14501E occupy different tiers, and the recorded data confirms a substantial performance gap. Since the i5-14501E has no benchmark scores in the database, all direct numerical comparisons rely on the Ultra 5's recorded results.

The Ultra 5 250KF Plus delivers a multi-core score of 42,718 in Cinebench R23, a result that places it in the 93rd percentile of all CPUs tracked by the database. This is a very strong showing for a desktop processor. In single-core Cinebench R23, it scores 6,030, which is also a high mark. For context, the Ultra 5's average benchmark score across all tests is 66,159, putting it just 0.1% ahead of the Intel Core 9 273PQE (average score 66,099) and 0.4% ahead of the AMD Ryzen 9 7950X3D (average score 65,914). The Ultra 5 trails the Intel Core Ultra 5 250K Plus by 1% (that chip averages 66,855) and the AMD EPYC 4465P by 1.1% (average 66,925).

Looking at the broader test suite, the Ultra 5 shows particular strength in integer math, scoring 123,030. The floating point math score is even higher at 159,824, indicating robust compute throughput for scientific and engineering workloads. Data compression work yields a score of 553,155, while data encryption reaches 41,292. The extended instructions score is 42,880, showing solid SIMD performance. Prime number finding is relatively lower at 452, which is typical for this type of workload. Random string sorting completes at 67,209, and the physics test posts 3,183.

The multicore Cinebench R15 result is 4,305, while the single-core R15 score is 607. In Cinebench R20, the Ultra 5 manages 17,941 multi-core and 2,532 single-core. The PassMark multithread score is 50,146, and single-thread performance is recorded at 4,698 in both the singlethread and single_thread entries.

The i5-14501E has no recorded benchmark scores, so its percentile ranking of 50 is a placeholder rather than a measured result. The database shows zero wins for the i5 and zero wins for the Ultra 5 in the head-to-head comparison, because no paired test data exists. However, the Ultra 5's absolute scores and its 93rd percentile position indicate that it would dominate the i5 in every measured workload category, given the i5's complete absence of recorded performance data.

Architecture Differences

The two processors come from different Intel generations and use fundamentally different designs. The Core i5-14501E is part of the Core 14th Gen series, built on Raptor Lake architecture (codename Raptor Lake-R). It uses a 10 nm process node fabricated by Intel. The Core Ultra 5 250KF Plus belongs to the Core Ultra Series 2, uses the Arrow Lake Refresh codename, and is built on a 3 nm process node at TSMC. The die sizes reflect this: the i5 measures 215 mm², while the Ultra 5 is larger at 243 mm².

Core counts differ sharply. The i5-14501E has 6 cores and 12 threads, indicating Hyper-Threading support. The Ultra 5 250KF Plus has 18 cores and 18 threads, meaning it does not use simultaneous multithreading; each core handles one thread. This is a notable design choice that emphasizes physical cores over logical threads.

Cache hierarchies are also different. The i5-14501E provides 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The Ultra 5 uses 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The larger per-core caches on the Ultra 5 align with its newer architecture and higher core count.

Clock speeds favor the Ultra 5 as well. The i5-14501E has a base clock of 3.30 GHz and a boost clock of 5.20 GHz. The Ultra 5 runs at 4.20 GHz base and 5.30 GHz boost. The Ultra 5 also has an unlocked multiplier, while the i5 is locked, meaning the Ultra 5 supports manual overclocking.

Memory support diverges. The i5-14501E supports both DDR4 and DDR5 memory over a dual-channel bus. The Ultra 5 supports only DDR5, also dual-channel, and has a recorded memory bandwidth of 115.2 GB/s. Both processors support ECC memory.

PCIe connectivity differs. The i5-14501E offers Gen 5 with 16 lanes from the CPU. The Ultra 5 provides Gen 5 with 20 lanes from the CPU, giving it additional headroom for expansion devices.

Integrated graphics separate the two. The i5-14501E includes UHD Graphics 770, while the Ultra 5 250KF Plus has no integrated graphics (listed as N/A). The "F" in the Ultra 5's name indicates this lack of iGPU, so a discrete graphics card is required.

Power targets differ substantially. The i5-14501E has a TDP of 65 watts, while the Ultra 5 250KF Plus is rated at 125 watts. The Ultra 5's higher power envelope supports its 18 physical cores and higher clock speeds.

The Ultra 5 uses Intel Socket 1851, while the i5-14501E uses Intel Socket 1700. These are not interchangeable, so motherboard selection is fixed by the processor choice. The Ultra 5 contains 17,800 million transistors, a figure not recorded for the i5.

Release timing is also different. The i5-14501E launched on June 30, 2024, and the Ultra 5 250KF Plus launched on March 10, 2026. Both are listed as Active in production status. The Ultra 5 has a launch MSRP of $184, while the i5 has no recorded launch price.

The Verdict

The recorded data points to a clear performance hierarchy. The Core Ultra 5 250KF Plus sits in the 93rd percentile of all CPUs, with an average benchmark score of 66,159. It is effectively tied with the AMD Ryzen 9 7950X3D (0.4% ahead) and the Intel Core 9 273PQE (0.1% ahead), while trailing the Core Ultra 5 250K Plus by 1% and the AMD EPYC 4465P by 1.1%. These are high-end competitors, and the Ultra 5 holds its ground within that group.

The Core i5-14501E has no recorded benchmark scores and a 50th percentile placeholder. Without measured data, the database cannot substantiate any performance claims for the i5. Its 6-core, 12-thread configuration, 10 nm process, and 65-watt TDP suggest a mainstream part, but no scores exist to quantify it.

For users who need multi-core throughput, the Ultra 5's 18 physical cores and 42,718 Cinebench R23 multi-core score are decisive. The 125-watt TDP and higher base clock of 4.20 GHz support sustained heavy workloads. The lack of integrated graphics means a discrete GPU is mandatory, but the additional 4 PCIe Gen 5 lanes (20 vs 16) provide expansion flexibility.

The i5-14501E, with its UHD Graphics 770, can operate without a discrete GPU. Its 65-watt TDP and DDR4 compatibility make it a lower-power option, though the database contains no scores to confirm its performance level. The 5.20 GHz boost clock suggests competitive single-thread capability, but that remains unverified in the recorded data.

The Ultra 5 is the only one of the two with measurable performance, and that performance is elite. The i5-14501E's role in the database is defined by its specifications rather than its results. Anyone choosing between these two based on the data would select the Ultra 5 for any compute-heavy task, accepting the need for a separate graphics card.

Where Each One Wins

The Core Ultra 5 250KF Plus wins in every category where recorded data exists. Its Cinebench R23 multi-core score of 42,718 demonstrates exceptional parallel processing capability, driven by 18 physical cores. The single-core score of 6,030 in the same test shows that it also leads in lightly threaded workloads. PassMark results reinforce this: integer math at 123,030, floating point math at 159,824, and data compression at 553,155 all indicate strong general compute performance. The unlocked multiplier allows further tuning, and the 20 PCIe Gen 5 lanes provide more connectivity than the i5's 16 lanes. The 115.2 GB/s memory bandwidth supports high-throughput applications.

The Core i5-14501E has no recorded benchmark scores, so it cannot claim a measured win in any workload. Its advantages are structural rather than performance-based. The 65-watt TDP makes it a lower-power option, and the integrated UHD Graphics 770 eliminates the need for a discrete GPU in basic systems. DDR4 support offers memory flexibility for older platforms. The 5.20 GHz boost clock indicates strong single-thread potential, though no data confirms it. The 6-core, 12-thread configuration with 24 MB of shared L3 cache is suitable for mainstream workloads, but the database provides no scores to validate its position.

For multi-core rendering, scientific computation, or any workload that scales with core count, the Ultra 5's 18 cores and 42,718 Cinebench R23 score are the clear choice. For single-thread tasks, the Ultra 5's 5.30 GHz boost and 6,030 Cinebench R23 single-core score also lead. The i5-14501E is a viable option only where its lower TDP, integrated graphics, or DDR4 support are priorities, but the measured data favors the Ultra 5 across the board.
