Intel Core 7 251E vs Intel Core i5-14490F Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs for the Intel Core 7 251E versus the Intel Core i5-14490F. The Intel Core 7 251E has no recorded benchmark scores, no average score, and no percentile ranking in the database at this time. The Intel Core i5-14490F, by contrast, has a full set of recorded measurements across Cinebench and Passmark workloads.

Because the Core 7 251E lacks any measured performance data, a numeric comparison of the two processors is not possible from the recorded information. What the database does provide is a complete profile for the i5-14490F and a structural profile for the Core 7 251E. The i5-14490F posts an average benchmark score of 38149, placing it in the 86th percentile among all CPUs in the database. Its nearest rivals, based on average score, include the Intel Core Ultra 5 245T at 38194, which sits 0.1 percent ahead, and the Intel Core i5-13600KF at 38103, which trails by 0.1 percent. The AMD Ryzen 7 250 records 38221, 0.2 percent higher, and the Intel Core i5-13600HX reaches 38261, 0.3 percent higher. These deltas are small, indicating that the i5-14490F performs essentially on par with a tight cluster of competing desktop and mobile parts.

For the i5-14490F, the Cinebench results show a multicore score of 2318 in R15, 9660 in R20, and 23000 in R23. Single-core scores are 327 in R15, 1363 in R20, and 3247 in R23. Passmark measurements include a multithread score of 28662 and a single-thread score of 3873. In specialized workloads, the i5-14490F records 340026 for data compression, 18225 for data encryption, 21731 for extended instructions, 122 for find prime numbers, 66558 for floating point math, 87844 for integer math, 2093 for physics, and 35608 for random string sorting. These figures establish a baseline for the i5-14490F. The Core 7 251E has no comparable measurements in the database, so any head-to-head analysis must rely on architectural specifications rather than benchmark outcomes.

Architecture Differences

The two processors share a manufacturing process node: both are built on Intel's 10 nm process and produced by Intel. Both use the Intel Socket 1700 platform, and both support DDR4 and DDR5 memory over a dual-channel memory bus. Both expose Gen 5 PCIe with 16 lanes from the CPU. Neither has an unlocked multiplier.

The core configurations diverge sharply. The Intel Core 7 251E has 24 cores and 32 threads. The Intel Core i5-14490F has 10 cores and 16 threads. The Core 7 251E belongs to the Bartlett Lake codename and the Core 7 generation, while the i5-14490F is part of the Raptor Lake architecture under the Raptor Lake-R codename and the Core 14th Gen series, specifically the Core i5 (Raptor Lake Refresh) generation. The Core 7 251E uses a die size of 257 mm², whereas the i5-14490F has a smaller die at 215 mm².

Cache hierarchies differ as well. Both allocate 80 KB of L1 cache per core. The Core 7 251E provides 2 MB of L2 cache per core and 36 MB of shared L3 cache. The i5-14490F provides 1.25 MB of L2 per core and 24 MB of shared L3 cache. The larger L2 and L3 allocations on the Core 7 251E align with its higher core count and thread count.

Clock speeds also differ. The Core 7 251E has a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The i5-14490F has a base clock of 2.50 GHz and a boost clock of 5.00 GHz. Both are rated at a 65 W TDP. The Core 7 251E supports ECC memory, while the i5-14490F does not. The Core 7 251E includes integrated graphics in the form of UHD Graphics 770; the i5-14490F has no integrated graphics, listed as N/A in the database.

Memory bandwidth is another distinction. The Core 7 251E records a memory bandwidth of 89.6 GB/s. The i5-14490F has no memory bandwidth figure in the database, so no direct comparison is available on that metric.

Release timing differs, with the Core 7 251E carrying a release date of January 12, 2025, and the i5-14490F carrying a release date of December 31, 2023. The Core 7 251E has a launch MSRP of $384. The i5-14490F has no launch MSRP recorded. Production status for both is listed as Active.

Where Each One Wins

Given the absence of benchmark data for the Core 7 251E, the analysis of where each processor wins must be drawn from the recorded specifications.

The Core 7 251E wins on raw thread count, offering 32 threads against the i5-14490F's 16 threads. This indicates a substantial advantage in heavily parallel workloads, such as rendering, compilation, and scientific computing, where additional threads translate directly into higher throughput. The Core 7 251E also provides a higher boost clock of 5.60 GHz versus 5.00 GHz, which suggests an advantage in lightly threaded tasks that scale with frequency, such as single-threaded Cinebench runs or Passmark's single-thread test. Its larger L3 cache of 36 MB versus 24 MB and larger per-core L2 cache of 2 MB versus 1.25 MB may reduce memory latency and improve performance in cache-sensitive workloads. The Core 7 251E further supports ECC memory, a feature absent on the i5-14490F, which matters for error-tolerant computing environments. Integrated UHD Graphics 770 on the Core 7 251E provides a display output capability that the i5-14490F lacks entirely.

The i5-14490F wins on measured performance, since it is the only one of the two with any benchmark scores in the database. Its 86th percentile ranking and average score of 38149 confirm that it is a capable desktop processor. Its higher base clock of 2.50 GHz versus 2.10 GHz suggests a potential advantage in workloads that remain at base frequency for extended periods, though the Core 7 251E's higher boost clock may override that in burst scenarios. The i5-14490F also uses a smaller die at 215 mm², which may imply lower manufacturing costs per die, though the database does not provide pricing for the i5-14490F.

In scenarios where the i5-14490F's recorded scores are relevant, the data shows strong single-thread performance: a Cinebench R23 single-core score of 3247 and a Passmark single-thread score of 3873. Its multicore Cinebench R23 score of 23000 demonstrates solid multi-threaded capability despite having fewer cores than the Core 7 251E. The i5-14490F's Passmark physics score of 2093 and floating point math score of 66558 provide additional reference points for compute-intensive applications.

For the Core 7 251E, no such measurements exist, so the database cannot confirm whether its architectural advantages translate into benchmark wins. The 24-core, 32-thread configuration and higher boost clock are the only indicators available.

The Verdict

The data in the database supports a clear distinction between the two processors. The Intel Core i5-14490F is a fully measured part with an 86th percentile ranking and an average benchmark score of 38149. Its nearest rivals cluster within 0.3 percent of its score, confirming that it competes directly with the Intel Core Ultra 5 245T, Intel Core i5-13600KF, AMD Ryzen 7 250, and Intel Core i5-13600HX. For any workload where benchmark scores matter, the i5-14490F has verified performance.

The Intel Core 7 251E, by contrast, has no measured performance in the database. Its specifications indicate a higher thread count, higher boost clock, larger cache, and ECC support, all of which point to a processor designed for parallel throughput and reliability. However, without benchmark data, the database cannot confirm how those specifications translate into real-world results.

A user requiring verified performance from recorded measurements should select the Intel Core i5-14490F, as its scores are on file and its percentile ranking is strong. A user prioritizing raw core count, thread count, boost frequency, cache capacity, and ECC functionality should consider the Intel Core 7 251E, but must do so without any benchmark confirmation. The choice depends on whether the user trusts measured data or architectural specifications, and the database currently supports only the former for the i5-14490F.
