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

Head-to-Head Benchmarks

The Intel Core i5-14501E has no recorded benchmark scores in the database. The Intel Core Ultra 5 245K, by contrast, has a full suite of measurements, which makes a direct numerical comparison impossible for most tests. The data shows that the Core Ultra 5 245K holds the only available scores, so all performance analysis must center on its absolute results and its position relative to other processors in the database.

The Core Ultra 5 245K posts a Cinebench R23 multi-core score of 25066 and a single-core score of 2132. Its Cinebench R20 results follow a similar pattern, with 15368 in multi-core and 2169 in single-core. The Cinebench R15 scores are 3850 and 322, respectively. These figures indicate a processor that competes strongly in both heavily threaded and lightly threaded workloads.

In PassMark tests, the Core Ultra 5 245K delivers a multi-thread score of 43047 and a single-thread score of 4714. Its integer math result is 98524, while floating point math reaches 130678. Data compression scores 458817, and data encryption records 33286. Extended instructions hit 37617, and random string sorting finishes at 55098. The physics test returns 3081, and the find prime numbers test scores 414.

The database places the Core Ultra 5 245K at the 91st percentile among all CPUs, with an average benchmark score of 54053. Its nearest rivals include the Intel Xeon 6505P at 53701, which is 0.7% slower; the Intel Core i7-14700F at 53620, which is 0.8% slower; and the Intel Xeon Phi 7290 at 53469, which is 1.1% slower. The AMD Ryzen 9 9900X3D scores 54762, putting the Core Ultra 5 245K 1.3% behind that chip. This grouping shows that the Core Ultra 5 245K sits in a tightly contested performance band, where the margins between adjacent processors are narrow.

Since the Core i5-14501E has zero benchmark entries, the head-to-head comparison cannot be resolved through measured scores. The record shows wins for each side as zero, confirming that no direct test data exists for the older chip. The analysis must therefore rely on architectural and specification differences to project how the two processors might behave, while acknowledging that no empirical results validate those projections.

Architecture Differences

The two processors come from entirely different design generations. The Core i5-14501E uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process node. The Core Ultra 5 245K uses the Arrow Lake architecture, specifically Arrow Lake-S, fabricated on TSMC's 3 nm node. The process shrink from 10 nm to 3 nm gives the newer chip a substantial manufacturing advantage in transistor density and power efficiency potential.

The Core Ultra 5 245K packs 17,800 million transistors into a die size of 243 mm². The Core i5-14501E has no transistor count recorded, but its die size is 215 mm². The transistor density difference is stark: the Arrow Lake chip crams far more transistors into a slightly larger die, which reflects the advanced 3 nm process.

Core counts differ significantly. The Core i5-14501E has 6 cores and 12 threads, meaning it relies on Hyper-Threading to reach its thread count. The Core Ultra 5 245K has 14 cores and 14 threads, with no Hyper-Threading. The newer chip doubles the core count while keeping threads equal to cores, a design choice that prioritizes physical cores over simultaneous multithreading.

Cache hierarchies also diverge. The Core i5-14501E has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The Core Ultra 5 245K has 192 KB of L1 per core, 3 MB of L2 per core, and the same 24 MB of shared L3. Per-core cache allocations are substantially larger on the Arrow Lake part, which can improve data locality and reduce memory latency for each core.

Clock speeds show a mixed picture. The Core i5-14501E has a base clock of 3.30 GHz and a boost clock of 5.20 GHz. The Core Ultra 5 245K has a base clock of 4.20 GHz and the same 5.20 GHz boost. The newer chip starts from a much higher base frequency but reaches the same maximum boost. The Core Ultra 5 245K also has an unlocked multiplier for overclocking, while the Core i5-14501E is locked.

Memory support differs. The Core i5-14501E supports both DDR4 and DDR5, while the Core Ultra 5 245K supports DDR5 only. Both run dual-channel memory. The Core Ultra 5 245K has a recorded memory bandwidth of 102.4 GB/s, while the Core i5-14501E has none listed. Both processors support ECC memory, which is notable for workstation and server-adjacent use cases.

PCIe lanes also differ. The Core i5-14501E provides PCIe Gen 5 with 16 CPU lanes, while the Core Ultra 5 245K provides PCIe Gen 5 with 20 CPU lanes. The extra four lanes on the newer chip can accommodate additional high-speed devices. Integrated graphics differ as well: the Core i5-14501E uses UHD Graphics 770, while the Core Ultra 5 245K uses Arc Xe-LPG Graphics with 64 execution units. The Arc part represents a newer, more capable graphics architecture. Socket compatibility is entirely different, with the Core i5-14501E on Intel Socket 1700 and the Core Ultra 5 245K on Intel Socket 1851.

Where Each One Wins

Without benchmark data for the Core i5-14501E, the database cannot show where that chip wins. The Core Ultra 5 245K, however, demonstrates clear strengths across every recorded test category. Its multi-core Cinebench R23 score of 25066 indicates strong performance in rendering and other parallel workloads. The PassMark multi-thread score of 43047 reinforces that picture.

The Core Ultra 5 245K shows particular strength in data compression, scoring 458817, and in floating point math, scoring 130678. These results suggest advantages in scientific computing, financial modeling, and multimedia processing. Integer math at 98524 and extended instructions at 37617 further support broad compute capability.

Single-thread performance for the Core Ultra 5 245K is also robust, with a Cinebench R23 single-core score of 2132 and a PassMark single-thread score of 4714. This indicates that the chip handles lightly threaded applications, such as legacy software or single-threaded games, competently.

For the Core i5-14501E, the only potential advantages come from specifications. Its 65 W TDP is substantially lower than the 125 W TDP of the Core Ultra 5 245K, which could translate into lower cooling requirements and quieter operation in compact systems. Support for DDR4 also gives the older chip a compatibility edge for users upgrading from existing DDR4 platforms, since they can reuse memory modules. The 6-core, 12-thread configuration with a 5.20 GHz boost clock may deliver respectable single-thread performance, but without measurements, this remains speculative.

The Verdict

The data supports a clear separation between these two processors. The Core Ultra 5 245K is the only one with recorded performance measurements, and those measurements place it at the 91st percentile among all CPUs. Its nearest rivals in the database are all within 1.3% of its average score, which places it in a highly competitive performance tier. The 14-core, 14-thread configuration, combined with the 3 nm process node and 102.4 GB/s memory bandwidth, gives it a strong foundation for demanding workloads.

The Core i5-14501E, with 6 cores and 12 threads on the older 10 nm Raptor Lake architecture, has no recorded benchmark scores. Its lower 65 W TDP and DDR4 support could appeal to users with existing DDR4 memory or strict power budgets. The 5.20 GHz boost clock matches the Core Ultra 5 245K, which suggests competitive single-thread performance, but the database offers no evidence to confirm this.

For users who prioritize measured performance and modern features, the Core Ultra 5 245K is the only chip with data supporting its capabilities. For users who need a lower-power part or wish to reuse DDR4 memory, the Core i5-14501E offers those specific advantages on paper, but the absence of benchmark results means its actual performance remains unverified. The database cannot certify any performance claim for the Core i5-14501E, while the Core Ultra 5 245K has a complete record of strong scores across rendering, math, compression, and general compute tasks.
