Intel Core 7 251E vs Intel Core i5-14500 Comparison

Intel Core 7 251E and Intel Core i5-14500 are both 65 W desktop processors on the Intel Socket 1700 platform, but the data shows they are built for different workloads. The 251E is a Bartlett Lake part with 24 cores and 32 threads, while the 14500 is a Raptor Lake Refresh part with 14 cores and 20 threads. The recorded benchmarks only cover the 14500, so the analysis relies on the specification differences and the 14500's measured performance against its nearest rivals.

Where Each One Wins

The Intel Core 7 251E wins on raw core count and thread count. It offers 24 cores and 32 threads, which is 10 more cores and 12 more threads than the 14500. This points to a clear advantage in heavily parallel workloads, such as software compilation, video rendering, and scientific computing. The 251E also has a higher boost clock at 5.60 GHz compared to 5.00 GHz on the 14500, suggesting an edge in bursty, single-threaded tasks that rely on peak frequency.

The Intel Core i5-14500 wins on measured benchmark performance, as it is the only one of the two with benchmark scores in the database. Its average benchmark score is 38531, and it sits at the 86th percentile among all CPUs. The 251E has no recorded benchmarks and a percentile of 50, which means the database has no performance data to confirm its theoretical advantages. The 14500 also has a higher base clock at 2.60 GHz versus 2.10 GHz on the 251E, which could help in sustained workloads where the processor stays at lower frequencies.

The 251E has a larger L3 cache at 36 MB shared, compared to 24 MB shared on the 14500. The 251E also has a larger L2 cache at 2 MB per core, while the 14500 has 1.25 MB per core. This cache advantage could benefit the 251E in data-heavy applications that repeatedly access large datasets. The 14500 counters with a smaller die size at 215 mm², which may indicate lower manufacturing complexity, though the 251E is rated at 257 mm².

Architecture Differences

The two processors use different architectures. The 251E is based on Bartlett Lake, while the 14500 uses Raptor Lake, specifically the Raptor Lake Refresh generation. Both are manufactured on a 10 nm process at Intel, and both have a 65 W TDP. The 251E has a die size of 257 mm², and the 14500 has a die size of 215 mm².

The core configurations differ significantly. The 251E has 24 cores and 32 threads, which implies a mix of performance and efficiency cores, though the exact split is not recorded. The 14500 has 14 cores and 20 threads, a typical hybrid layout for Raptor Lake. The 251E has a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The 14500 has a base clock of 2.60 GHz and a boost clock of 5.00 GHz. The 251E's higher boost clock is notable, but its lower base clock suggests it may idle or run at lower frequencies more often.

Cache hierarchies differ as well. Both have 80 KB of L1 cache per core. The L2 cache is 2 MB per core on the 251E and 1.25 MB per core on the 14500. The L3 cache is 36 MB shared on the 251E and 24 MB shared on the 14500. The 251E has a memory bandwidth of 89.6 GB/s, while the 14500 has no recorded memory bandwidth figure. Both support DDR4 and DDR5 memory, dual-channel memory buses, and ECC memory. Both also use PCIe Gen 5 with 16 lanes from the CPU, and both include UHD Graphics 770 integrated graphics.

The release dates differ. The 14500 was released on 2024-01-07, and the 251E was released on 2025-01-12. The 251E has a launch MSRP of $384, and the 14500 has a launch MSRP of $232. Both processors have locked multipliers.

Head-to-Head Benchmarks

The database has no direct head-to-head benchmark results between the 251E and the 14500. The 251E has no benchmark scores recorded, so the comparison must rely on the 14500's measured performance and the specification gaps.

The 14500's Cinebench R23 multicore score is 15012, and its single-core score is 1917. In Cinebench R20, it scores 10985 multicore and 1550 single-core. In Cinebench R15, it scores 2435 multicore and 273 single-core. These scores show strong multi-threaded performance for a 14-core part. The 251E's 24 cores and 32 threads would likely improve on these numbers in multicore tests, but the database does not confirm this.

Geekbench scores for the 14500 are 13390 multicore and 2099 single-core. The PassMark suite shows a multithread score of 30777 and a single-thread score of 3952. The 14500 also records specific workload scores: data compression at 371294, data encryption at 21457, extended instructions at 22473, find prime numbers at 106, floating point math at 79576, integer math at 108124, physics at 1746, and random string sorting at 40980.

The 14500's nearest rivals in the database are all close in average score. The Intel Core Ultra 5 235T has an average score of 38561, which is 0.1% higher. The Intel Xeon w3-2525 has an average score of 38392, which is 0.4% lower. The Intel Core 9 270H has an average score of 38335, which is 0.5% lower. The Intel Core Ultra 9 285H has an average score of 38312, which is 0.6% lower. These small deltas indicate the 14500 is tightly grouped with these processors, none of which is the 251E.

The 251E's higher core count and larger caches suggest it could outperform the 14500 in multicore workloads, but its lack of benchmark data means the database cannot substantiate that. The 14500, by contrast, has verified performance across multiple suites, and its 86th percentile ranking is a concrete data point.

The Verdict

The data supports the Intel Core i5-14500 as the processor with confirmed performance. It has a full set of benchmark scores, an average benchmark score of 38531, and an 86th percentile ranking. The 251E has no recorded benchmarks, so its actual performance is unknown in the database.

The Intel Core 7 251E is the processor for workloads that scale with core count and cache size. Its 24 cores, 32 threads, 36 MB of L3 cache, and 2 MB of L2 cache per core are all higher than the 14500's 14 cores, 20 threads, 24 MB of L3 cache, and 1.25 MB of L2 cache per core. Its boost clock of 5.60 GHz also exceeds the 14500's 5.00 GHz. These specifications suggest an advantage in multi-threaded rendering, compilation, and server-like tasks, but the lack of benchmarks leaves this as a projection rather than a measurement.

The 14500 is the processor for workloads where measured results matter. Its Cinebench R23 multicore score of 15012 and single-core score of 1917, along with its PassMark multithread score of 30777, are verified data points. Its base clock of 2.60 GHz is higher than the 251E's 2.10 GHz, which may help in sustained workloads that do not reach boost frequencies.

The release timing and MSRP are also recorded. The 14500 launched on 2024-01-07 with a launch MSRP of $232. The 251E launched on 2025-01-12 with a launch MSRP of $384. The database does not include pricing analysis beyond these figures.
