Intel Core 7 251E vs Intel Core Ultra 5 245 Comparison

Intel Core 7 251E and Intel Core Ultra 5 245 are both active desktop processors from Intel, but they represent fundamentally different approaches. The Core 7 251E uses the older Bartlett Lake design on Intel’s 10 nm process, while the Core Ultra 5 245 is built on Arrow Lake using TSMC’s 3 nm node. The database contains benchmark results only for the Core Ultra 5 245, with no recorded measurements for the Core 7 251E. Consequently, direct head-to-head performance comparisons rely entirely on architectural and specification data rather than empirical test scores.

Head-to-Head Benchmarks

The recorded data shows the Intel Core Ultra 5 245 delivering a strong single-thread performance profile. In Cinebench R23 single-core, it scores 4648 points, and in Cinebench R20 single-core, it reaches 1952 points. The PassMark single-thread test records 4394 points, with the same value appearing under the singlethread test name. These results place the Core Ultra 5 245 in the 90th percentile among all CPUs, indicating top-tier performance for lightly threaded workloads.

Multi-threaded results for the Core Ultra 5 245 are equally substantial. Cinebench R23 multi-core yields 32924 points, while Cinebench R20 multi-core produces 13828 points. The older Cinebench R15 test shows 3318 points multi-core and 468 points single-core. PassMark multithread scores 38706, with integer math at 91187 and floating point math at 120548. Data compression in PassMark reaches 400942, encryption scores 30236, and extended instructions hit 33304. Random string sorting records 49140, and find prime numbers scores 365. Physics testing in PassMark shows 2569 points.

The Core Ultra 5 245 achieves an average benchmark score of 48995. Its nearest rivals in the database include the AMD Ryzen 7 PRO 5755G with an average score of 49196, representing a 0.4 percent difference, and the AMD Ryzen 9 7900 with 49228, a 0.5 percent difference. The Intel Xeon Gold 5318H scores 48698, which is 0.6 percent higher, and the Intel Core i5-14600K scores 48618, sitting 0.8 percent higher. These small deltas indicate the Core Ultra 5 245 performs within a tight band around comparable processors.

Because the Core 7 251E has no benchmark entries in the database, no wins can be assigned to either processor. The head-to-head benchmark list is empty, and both processors record zero wins in the comparison. Any assessment of relative performance must therefore rely on the architectural differences and the Core Ultra 5 245’s measured scores alone.

The Verdict

The data indicates the Intel Core Ultra 5 245 is the processor with verified performance credentials. Its 90th percentile ranking and average benchmark score of 48995 place it firmly among capable desktop CPUs. The nearest rivals, including the AMD Ryzen 7 PRO 5755G and the Intel Core i5-14600K, sit within one percent of its average score, showing that the Core Ultra 5 245 competes effectively in its segment.

The Intel Core 7 251E presents a contrasting profile. With 24 cores and 32 threads, it offers more parallel resources on paper, but without benchmark data, its real-world performance cannot be quantified. The Core Ultra 5 245 has 14 cores and 14 threads, yet its recorded Cinebench R23 multi-core score of 32924 demonstrates substantial throughput despite the lower core count. This suggests architectural efficiency in the Arrow Lake design compensates for fewer physical cores.

For workloads that depend on single-thread speed, the Core Ultra 5 245’s Cinebench R23 single-core score of 4648 and PassMark single-thread result of 4394 provide concrete evidence of strong performance. The Core 7 251E has no comparable measurements. For heavily threaded tasks, the Core 7 251E’s higher core and thread counts could theoretically provide an advantage, but the absence of test results prevents confirmation. The Core Ultra 5 245 remains the only processor in this comparison with validated performance data.

Architecture Differences

The Core 7 251E belongs to the Bartlett Lake codename family, with generation listed as Core 7 (Bartlett Lake). The Core Ultra 5 245 uses the Arrow Lake architecture under the codename Arrow Lake-S, with generation Ultra 5 (Arrow Lake). The Core Ultra 5 245 is part of the Core Ultra Series 2, while the Core 7 251E has no series designation.

Process technology separates the two clearly. The Core 7 251E is fabricated on Intel’s 10 nm node, while the Core Ultra 5 245 uses TSMC’s 3 nm process. Transistor counts are only recorded for the Core Ultra 5 245, at 17,800 million. Die sizes are 257 mm² for the Core 7 251E and 243 mm² for the Core Ultra 5 245.

Cache layouts differ substantially. The Core 7 251E has 80 KB of L1 cache per core and 2 MB of L2 cache per core, with 36 MB of shared L3 cache. The Core Ultra 5 245 has 192 KB of L1 cache per core and 3 MB of L2 cache per core, with 24 MB of shared L3 cache. The larger per-core L1 and L2 allocations in the Core Ultra 5 245 suggest a design optimized for per-thread efficiency, while the Core 7 251E emphasizes larger aggregate L3 capacity.

The Core Ultra 5 245’s 3 nm TSMC process gives it a manufacturing advantage in density and power characteristics, though the Core 7 251E compensates with a higher boost clock of 5.60 GHz versus 5.10 GHz. The Core Ultra 5 245 also supports more PCIe lanes, 20 versus 16, which could benefit systems with multiple NVMe drives or expansion cards. Both processors support ECC memory, a feature often associated with workstation-class stability.

The integrated graphics solutions are from different generations. UHD Graphics 770 in the Core 7 251E is a conventional Intel iGPU, while Arc Xe-LPG Graphics 64EU in the Core Ultra 5 245 represents a newer graphics architecture. The Core Ultra 5 245’s higher memory bandwidth, 102.4 GB/s versus 89.6 GB/s, further supports integrated graphics performance by feeding the GPU with more data.
