Intel Core i5-14501E vs Intel Core Ultra 9 285K Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 9 285K delivers an overwhelming performance advantage across every recorded benchmark. Since the benchmark database contains no measured scores for the Intel Core i5-14501E, the comparison relies entirely on the 285K's recorded results, which position it in the 96th percentile of all CPUs. That percentile ranking places it far ahead of the i5-14501E, which sits at the 50th percentile, a gap that indicates the 285K outperforms the majority of desktop processors while the i5-14501E lands in the middle of the pack.

The 285K's multi-core results are particularly decisive. In Cinebench R23 multi-core, it scores 42,522 points, while in Cinebench R20 multi-core it reaches 24,003, and in Cinebench R15 multi-core it hits 6,494. These scores reflect a processor built for sustained heavy workloads. The single-core results, while less dramatic, still show strength: Cinebench R23 single-core at 2,377, Cinebench R20 single-core at 3,388, and Cinebench R15 single-core at 359. The difference between the multi-core and single-core scaling suggests the 285K benefits massively from its core count and thread allocation.

Geekbench results confirm the pattern. The 285K records a multi-core score of 26,702 and a single-core score of 2,870. The ratio between these two scores, roughly 9.3 to 1, indicates strong parallel scaling across the chip's 24 cores. The i5-14501E, with only 6 cores and 12 threads, would be expected to show a far smaller gap between single-threaded and multi-threaded performance, though no direct measurements exist in the database to confirm this.

PassMark results add further detail. The 285K achieves a multi-thread score of 67,260 and a single-thread score of 5,087. In specialized workloads, it records 172,379 in integer math, 224,324 in floating point math, 62,277 in extended instructions, and 790,052 in data compression. Data encryption scores 57,745, while random string sorting reaches 94,927. The physics test scores 3,938, and the find prime numbers test scores 541. These figures illustrate a processor that handles both arithmetic-heavy and memory-intensive tasks with high throughput.

The 285K's average benchmark score stands at 83,807. Its nearest rivals in the database are the Intel Core Ultra 9 290K Plus with an average score of 84,003 (0.2% ahead), the AMD EPYC 4584PX at 83,090 (0.9% behind), the AMD EPYC 9135 at 82,980 (1% behind), and the AMD EPYC 7F72 at 85,072 (1.5% ahead). These small deltas indicate that the 285K competes at the very top of the desktop and workstation segments, trading places with high-end EPYC server parts. The i5-14501E has no recorded rivals or benchmark scores, leaving its exact positioning unmeasured but its percentile rank suggests a mid-range standing.

Architecture Differences

The two processors come from different generations and foundries. The Intel Core i5-14501E uses Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process. The Intel Core Ultra 9 285K uses Arrow Lake architecture, specifically Arrow Lake-S, built on TSMC's 3 nm process. This process difference is significant: the 3 nm node allows far denser transistor packing, and the 285K contains 17,800 million transistors on a 243 mm² die. The i5-14501E has no transistor count recorded, but its die size is 215 mm² on a larger process node.

Core configuration differs sharply. The i5-14501E provides 6 cores and 12 threads, indicating hyper-threading support. The 285K provides 24 cores and 24 threads, meaning no hyper-threading; each core maps to one thread. Despite having twice the threads per core on the i5-14501E, the 285K's fourfold core count gives it a structural advantage in parallel workloads. Clock speeds also favor the 285K: its base clock is 3.70 GHz and boost clock is 5.70 GHz, versus 3.30 GHz base and 5.20 GHz boost on the i5-14501E. Both boost clocks exceed 5 GHz, but the 285K holds the edge in both metrics.

Cache hierarchies reflect the architectural leap. The i5-14501E has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The 285K has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The larger per-core caches on the 285K reduce latency for frequently accessed data, while the larger shared L3 pool benefits multi-core workloads that share data. The i5-14501E's total L2, at 7.5 MB across six cores, is smaller than the 285K's 72 MB across 24 cores, a substantial difference in on-die storage.

Memory support diverges as well. The i5-14501E supports both DDR4 and DDR5 memory in a dual-channel configuration. The 285K supports only DDR5 but provides a recorded memory bandwidth of 102.4 GB/s. Both support ECC memory, a feature useful for workstation reliability. The PCIe configurations differ: the i5-14501E provides Gen 5 with 16 lanes from the CPU, while the 285K provides Gen 5 with 20 lanes from the CPU, giving the newer chip more room for expansion cards and NVMe storage.

Integrated graphics also differ. The i5-14501E uses UHD Graphics 770, while the 285K uses Arc Xe-LPG Graphics with 64 execution units. The socket changes as well: the i5-14501E uses Intel Socket 1700, while the 285K uses Intel Socket 1851. The 285K has an unlocked multiplier, enabling overclocking, while the i5-14501E does not. The 285K's launch MSRP is $589, stated once here as recorded. The i5-14501E has no launch MSRP in the database.

Where Each One Wins

The Intel Core Ultra 9 285K wins in every measured category. Its multi-core benchmark results, including Cinebench R23 at 42,522 and PassMark multi-thread at 67,260, make it suitable for rendering, video encoding, scientific simulation, and any workload that scales across many cores. The 24-core design with 24 threads, combined with the 36 MB L3 cache and 102.4 GB/s memory bandwidth, supports parallel processing with minimal bottlenecking.

The 285K also leads in single-threaded performance, with a PassMark single-thread score of 5,087 and a Geekbench single-core score of 2,870. This matters for applications that rely on per-core speed, such as legacy software, certain games, and lightly threaded productivity tools. The boost clock of 5.70 GHz is the highest recorded between the two chips.

The i5-14501E, with no recorded benchmarks, cannot claim a measured win in any category. Its specifications, however, suggest a different use profile. The 65 W TDP, versus the 285K's 125 W TDP, indicates lower power draw. The support for DDR4 memory allows the i5-14501E to slot into existing DDR4 platforms, potentially easing upgrades for systems already using that memory standard. The 6-core, 12-thread configuration with a 5.20 GHz boost clock provides respectable single-thread performance for everyday desktop tasks, though the database records no scores to quantify this.

The 285K's unlocked multiplier and 20 PCIe Gen 5 lanes make it the stronger choice for enthusiasts and workstation builders who want overclocking headroom and expansion capability. The i5-14501E's locked multiplier and 16 PCIe Gen 5 lanes target more conservative builds. The 285K's 96th percentile ranking versus the i5-14501E's 50th percentile confirms that the newer chip sits in a completely different performance class.

The Verdict

The recorded data strongly favors the Intel Core Ultra 9 285K. Its 96th percentile ranking, 83,807 average benchmark score, and wins in every measured benchmark make it the clear choice for users who prioritize raw performance. The 24-core, 24-thread configuration, 5.70 GHz boost clock, and 36 MB L3 cache deliver top-tier multi-threaded and single-threaded results. The nearest rivals, all within 1.5% of its average score, confirm that the 285K competes with high-end server and workstation chips.

The Intel Core i5-14501E, with no recorded benchmarks and a 50th percentile ranking, occupies a mid-range position. Its 6 cores and 12 threads, 5.20 GHz boost clock, and 65 W TDP suggest a lower-power, mainstream desktop processor. The DDR4 support and smaller cache footprint indicate a design aimed at cost-conscious builds rather than peak performance. The 285K, with its 125 W TDP, unlocked multiplier, and 20 PCIe Gen 5 lanes, targets enthusiasts and professionals who need maximum throughput and expansion headroom. Users requiring the best recorded performance should select the 285K. Users constrained by power or existing DDR4 platforms might consider the i5-14501E, though the database provides no measured scores to quantify its capabilities.
