Intel Core i5-14501E vs Intel Core Ultra 5 245KF Comparison

Head-to-Head Benchmarks

The benchmark database contains no head-to-head records directly comparing the Intel Core i5-14501E and the Intel Core Ultra 5 245KF. The recorded data for the Core Ultra 5 245KF, however, provides a detailed performance profile. The Core i5-14501E carries no benchmark scores in the database, with an average benchmark score of 0 and a percentile rank of 50 among all CPUs. The Core Ultra 5 245KF, by contrast, shows an average benchmark score of 55,093 and sits at the 91st percentile, a substantial gap in overall measured performance.

Looking at the Core Ultra 5 245KF's individual results, the Cinebench R23 multicore score reaches 36,647, while the single-core score is 5,173. In Cinebench R20, the multicore result is 15,391 and single-core is 2,172. The Cinebench R15 run produces a multicore score of 3,693 and a single-core score of 521. These numbers indicate a strong balance between heavily threaded workloads and lightly threaded tasks.

In PassMark tests, the Core Ultra 5 245KF delivers a multithread score of 43,110 and a single-thread score of 4,715. Data compression reaches 460,123, which is a notably high figure compared to other workloads. Data encryption scores 33,381, and extended instructions hit 37,912. Floating point math scores 131,546, integer math 98,854, and the find prime numbers test yields 416. Random string sorting produces 55,206, and physics simulation scores 2,998.

Since the Core i5-14501E has no recorded benchmarks, the head-to-head comparison is one-sided: the data shows wins only for the Core Ultra 5 245KF. The 91st percentile placement for the Ultra 5, relative to a 50th percentile for the i5-14501E, suggests the Ultra 5 occupies a far higher tier in the database's overall rankings. The nearest rivals listed for the Ultra 5 include the AMD Ryzen 9 9900X3D with an average score of 54,762 and a delta of 0.6%, meaning the Ultra 5 is essentially level with that part. The Intel Core 7 253PQE scores 55,919 with a delta of -1.5%, indicating the Ultra 5 trails slightly. The Intel Core i9-14900HX scores 56,004 with a delta of -1.6%. The Intel Core Ultra 5 245K scores 54,053 with a delta of 1.9%, meaning the 245KF leads its direct sibling by that margin.

Architecture Differences

The two processors come from different architectural generations. The Intel Core i5-14501E is built on Raptor Lake, specifically the Raptor Lake-R refresh, part of the Core 14th Gen series. The Core Ultra 5 245KF uses Arrow Lake, designated Arrow Lake-S, in the Core Ultra Series 2. The process node differs sharply: the i5-14501E uses a 10 nm node fabricated by Intel, while the Ultra 5 245KF uses a 3 nm node fabricated by TSMC. The Ultra 5's transistor count is listed at 17,800 million, while the i5-14501E has no transistor count recorded. Die size also differs, with the i5-14501E at 215 mm² and the Ultra 5 at 243 mm².

Core and thread counts diverge significantly. The i5-14501E has 6 cores and 12 threads, while the Ultra 5 245KF has 14 cores and 14 threads. The Ultra 5's thread count equals its core count, indicating no hyperthreading on its P-cores, whereas the i5-14501E doubles its threads through hyperthreading. Base clocks differ as well: the i5-14501E starts at 3.30 GHz and the Ultra 5 at 4.20 GHz. Both share the same boost clock of 5.20 GHz.

Cache hierarchies show clear differences. The i5-14501E has 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The Ultra 5 245KF has 192 KB of L1 per core, 3 MB of L2 per core, and also 24 MB of shared L3. The larger per-core caches on the Ultra 5 result in a much larger total L2 capacity across its 14 cores.

Memory support changes too. The i5-14501E supports both DDR4 and DDR5, while the Ultra 5 245KF supports DDR5 only. Both are dual-channel, but the Ultra 5 has a recorded memory bandwidth of 102.4 GB/s, a figure absent for the i5-14501E. ECC memory is supported on the i5-14501E but not on the Ultra 5. PCIe lanes differ: the i5-14501E offers Gen 5 with 16 lanes from the CPU, while the Ultra 5 245KF offers Gen 5 with 20 lanes from the CPU.

Integrated graphics also split the two. The i5-14501E includes UHD Graphics 770, whereas the Ultra 5 245KF has no integrated graphics (N/A). The sockets are incompatible: the i5-14501E uses Intel Socket 1700, and the Ultra 5 245KF uses Intel Socket 1851. The multiplier is locked on the i5-14501E and unlocked on the Ultra 5 245KF, meaning the latter allows overclocking. The TDP figures are 65 watts for the i5-14501E and 125 watts for the Ultra 5 245KF.

Where Each One Wins

Given the absence of benchmark scores for the Core i5-14501E, the data cannot assign any workload wins to that processor. The Core Ultra 5 245KF, with a full suite of recorded results, wins across every measured category in the database. The 14 cores versus 6 cores gives the Ultra 5 a structural advantage in heavily parallel tasks such as Cinebench R23 multicore, where its 36,647 score reflects strong scaling. PassMark multithread at 43,110 reinforces this, and data compression at 460,123 shows particular strength in memory-intensive, thread-heavy operations.

Single-threaded performance also favors the Ultra 5, with a Cinebench R23 single-core score of 5,173 and a PassMark single-thread score of 4,715. The higher base clock of 4.20 GHz, combined with the newer 3 nm process, likely contributes to this lead. The i5-14501E's 5.20 GHz boost clock matches the Ultra 5's, but the older 10 nm node and smaller per-core caches would constrain its single-thread ceiling in the absence of measured data.

For workloads that benefit from per-core cache, the Ultra 5's 192 KB of L1 and 3 MB of L2 per core provide a clear advantage over the i5-14501E's 80 KB and 1.25 MB. Integer math at 98,854 and floating point math at 131,546 on the Ultra 5 indicate robust arithmetic throughput. The find prime numbers test, scoring 416, is a low absolute value but still represents a recorded win for the Ultra 5 since the i5-14501E has no score. Physics simulation at 2,998 and random string sorting at 55,206 round out the Ultra 5's coverage across varied computational patterns.

The i5-14501E's potential wins would be limited to qualitative factors: its support for DDR4 memory could make it compatible with older platforms, and its integrated UHD Graphics 770 provides a display output without a discrete GPU. ECC memory support is another differentiator, relevant for error-sensitive workloads. These are feature-based distinctions, not benchmark victories, and the database provides no performance data to substantiate any computing win for the i5-14501E.

The Verdict

The recorded data points decisively toward the Intel Core Ultra 5 245KF. Its 91st percentile ranking versus the i5-14501E's 50th percentile, combined with an average score of 55,093 against 0, establishes a clear performance hierarchy. The Ultra 5's 14 cores, 14 threads, 4.20 GHz base clock, and 3 nm process from TSMC provide the structural basis for its benchmark results. The nearest rival data reinforces this: the Ultra 5 sits within 1.9% of the Intel Core Ultra 5 245K, within 1.6% of the Intel Core i9-14900HX, and within 1.5% of the Intel Core 7 253PQE, while leading the AMD Ryzen 9 9900X3D by 0.6%. These are all high-end parts, confirming the Ultra 5's placement among strong performers.

For users seeking maximum measured performance across all benchmark categories, the Core Ultra 5 245KF is the only choice supported by data. Its unlocked multiplier and 125 W TDP indicate headroom for overclocking, and its 20 PCIe Gen 5 lanes provide more expansion bandwidth. The i5-14501E, however, retains qualitative advantages: DDR4 compatibility, ECC memory support, integrated graphics, and a lower 65 W TDP. The database shows no benchmark scores for the i5-14501E, so any performance expectations for it remain unverified. The verdict from the recorded data is straightforward: the Core Ultra 5 245KF delivers all measured performance wins, while the i5-14501E offers feature-based flexibility for specific platform needs.
