Intel Core i5-14501E vs Intel Core Ultra 7 255H Comparison

The Intel Core i5-14501E and the Intel Core Ultra 7 255H occupy different corners of the Intel product stack, one aimed at desktop systems and the other at mobile platforms. The database shows a clear performance disparity between the two, driven by fundamentally different design philosophies, process nodes, and core configurations. This analysis examines the recorded benchmark data, architectural differences, and specification gaps to clarify what each processor delivers.

Head-to-Head Benchmarks

The Core Ultra 7 255H holds a decisive advantage across every recorded benchmark test in the database. The largest margin appears in the PassMark data compression test, where the Ultra 7 scores 298850, while the i5-14501E has no recorded score in any benchmark category. Since the i5-14501E lacks benchmark entries entirely, the comparison rests entirely on the Ultra 7's absolute performance numbers and its position relative to other processors.

The Ultra 7 255H produces a Cinebench R23 multi-core score of 9240 and a single-core score of 1843. In Cinebench R20, the multi-core result is 6381, with a single-core score of 900. The older Cinebench R15 test shows 1515 for multi-core and 251 for single-core. Geekbench results show 14024 for multi-core and 2335 for single-core. These figures place the Ultra 7 in the 83rd percentile of all CPUs tracked in the database, with an average benchmark score of 33537.

The nearest rivals in the database provide context for the Ultra 7's standing. The AMD Ryzen 5 240 posts an average score of 33542, which is effectively identical to the Ultra 7's 33537 (a 0.0% difference). The AMD Ryzen 7 8840HS and AMD Ryzen 5 7645HX each score 33667, putting them 0.4% ahead of the Ultra 7. The Intel Core i5-12600HX scores 33375, which is 0.5% behind the Ultra 7. This cluster of scores indicates the Ultra 7 255H sits in a tightly contested performance band, trading blows with comparable mobile and desktop processors.

Because the i5-14501E has no benchmark scores in the database, its percentile ranking stands at 50, and its average benchmark score is recorded as 0. The database therefore cannot show any head-to-head wins for the i5-14501E. All wins in this comparison belong to the Ultra 7 255H, with the caveat that the absence of data for the i5-14501E limits the depth of this analysis. The recorded numbers for the Ultra 7, particularly the PassMark integer math score of 77975 and floating point math score of 98796, indicate strong computational throughput, while the extended instructions score of 23755 shows capable vector and encryption workloads. The find prime numbers score of 303 and random string sorting score of 36058 round out the PassMark suite.

The single-thread PassMark score of 4317 for the Ultra 7 is notable, as it appears twice in the database under slightly different test names, confirming consistency in the measurement. The multi-thread PassMark score of 30703 reflects the 16-core configuration, while the physics score of 2254 and data encryption score of 23395 add further detail to the performance profile.

Architecture Differences

The architectural gap between these two processors is substantial. The i5-14501E uses the Raptor Lake architecture, specifically the Raptor Lake-R codename, and belongs to the Core 14th Gen series under the Core i5 (Raptor Lake Refresh) generation. It is built on a 10 nm process node at Intel's own foundry, with a die size of 215 mm². The Ultra 7 255H uses the Arrow Lake architecture with the Arrow Lake-H codename, part of the Core Ultra Series 2 under the Ultra 7 (Arrow Lake-H) generation. It is fabricated on a 3 nm process node at TSMC, and the database does not record a die size for this part.

The process node difference is significant: 10 nm for the desktop part versus 3 nm for the mobile part. This represents a major manufacturing advancement, allowing the Ultra 7 to pack more transistors into a smaller area, though the database does not list transistor counts for either processor. The foundry switch from Intel to TSMC for the Ultra 7 also marks a strategic divergence within Intel's product lines.

Core counts differ sharply. The i5-14501E has 6 cores and 12 threads, indicating hyper-threading support. The Ultra 7 255H has 16 cores and 16 threads, meaning no hyper-threading, with each core handling a single thread. The Ultra 7 thus offers more than double the core count, but the i5-14501E's 12 threads from 6 cores show a different approach to parallelism. The cache hierarchy also differs: the i5-14501E has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, while the Ultra 7 has 192 KB of L1 per core and 3 MB of L2 per core. Both share 24 MB of L3 cache, making the total cache arrangement similar at the last level but larger at the lower levels for the Ultra 7.

The memory support differs as well. The i5-14501E supports DDR4 and DDR5 in a dual-channel configuration, while the Ultra 7 supports DDR5 and LPDDR5X, also dual-channel. The database records a memory bandwidth of 102.4 GB/s for the Ultra 7, a figure not listed for the i5-14501E. Both processors support ECC memory, a notable feature for reliability-focused workloads.

The integrated graphics differ: the i5-14501E includes UHD Graphics 770, while the Ultra 7 includes Arc Graphics 140T. This represents a generational leap in integrated GPU capability, with the Arc branding indicating a more modern graphics architecture. The PCIe support also differs, with the i5-14501E offering Gen 5 with 16 lanes from the CPU, while the Ultra 7 offers Gen 5 with 20 lanes from the CPU.

The socket types are incompatible: the i5-14501E uses Intel Socket 1700, a desktop socket, while the Ultra 7 uses Intel BGA 2049, a ball-grid array for mobile. This means the two are not interchangeable in any system. The market segments confirm this: the i5-14501E is marked as Desktop, while the Ultra 7 is marked as Mobile.

Where Each One Wins

Based strictly on the recorded data, the Ultra 7 255H wins in every benchmark category. The i5-14501E has no benchmark scores in the database, so it cannot claim a single measured win. The Ultra 7's scores across Cinebench, Geekbench, and PassMark all indicate strong performance, particularly in multi-threaded workloads.

The Ultra 7's 16 cores give it an advantage in heavily parallel tasks, as evidenced by the Cinebench R23 multi-core score of 9240 and the PassMark multi-thread score of 30703. The single-core scores, such as the Geekbench single-core result of 2335 and Cinebench R23 single-core of 1843, also show strong per-thread performance despite the lower base clock.

The i5-14501E's higher base clock of 3.30 GHz and boost clock of 5.20 GHz could theoretically benefit single-threaded tasks, but no benchmark data exists to confirm this. The database records no test results for this processor, so any performance claim for the i5-14501E cannot be substantiated.

The Ultra 7 also wins on power efficiency, with a TDP of 28 watts compared to 65 watts for the i5-14501E. This makes the Ultra 7 suitable for battery-powered devices, while the i5-14501E targets desktop systems where power draw is less constrained.

The integrated graphics comparison favors the Ultra 7, as Arc Graphics 140T represents a more modern GPU architecture than UHD Graphics 770, though the database does not include graphics benchmark scores.

The Verdict

The data in the database points decisively toward the Intel Core Ultra 7 255H for any workload measured. Its 16 cores, 3 nm process node, and 24 MB of L3 cache combine to produce benchmark scores that place it in the 83rd percentile of all CPUs, with an average score of 33537. The i5-14501E, with no recorded benchmarks, cannot compete on measured performance.

For users who prioritize multi-threaded performance, the Ultra 7's Cinebench and PassMark scores demonstrate clear capability. For those who value power efficiency, the 28 watt TDP versus 65 watts is a substantial difference. For mobile use, the Ultra 7 is the only option, as the i5-14501E is a desktop part with a different socket.

The i5-14501E's higher clocks and lower core count might appeal to users who need fewer threads, but the absence of any benchmark data means the database cannot support such a claim. The 50th percentile ranking for the i5-14501E, paired with an average score of 0, reflects the lack of recorded measurements.

Both processors support ECC memory, which could matter for specific reliability-focused applications. Both use Gen 5 PCIe, though the Ultra 7 offers more lanes. The Ultra 7's support for LPDDR5X memory opens up lower-power memory options that the i5-14501E cannot use.

The release timeline shows the Ultra 7 arriving about six months after the i5-14501E, with the newer process node enabling a denser core configuration. The foundry shift to TSMC for the Ultra 7 represents a notable change in Intel's manufacturing approach.

In practical terms, the Ultra 7 255H serves mobile platforms with high computational demands, while the i5-14501E serves desktop systems that may prioritize higher base clocks and a mature socket ecosystem. The database shows the Ultra 7 as the superior performer in every measured category, and the i5-14501E as a processor without recorded benchmark results. Any selection between these two should account for the platform requirements, as the socket and market segment differences make them non-interchangeable.
