Intel Core 7 251TE vs Intel Core Ultra 9 386H Comparison

Head-to-Head Benchmarks

The benchmark data for the Intel Core Ultra 9 386H and the Intel Core 7 251TE reveals a split personality contest. The Ultra 9 386H wins 13 of the 17 recorded head-to-head tests, while the Core 7 251TE takes 4. The overall average benchmark scores are close, 43210 for the Ultra 9 386H and 41650 for the Core 7 251TE, placing both in the 88th percentile of all CPUs in the database. However, the nature of the wins tells the real story.

The most dramatic victory for the Ultra 9 386H comes in PassMark's find prime numbers test, where it scores 341 versus 140, a 143.6% advantage. This is a massive gap that points to a significant difference in how the two processors handle certain integer workloads. Similarly, in extended instructions, the Ultra 9 386H posts 29138 against 16974 for the Core 7 251TE, a 71.7% lead. These are not marginal differences; they are category-level gaps.

In multi-core Cinebench tests, the results are mixed across versions. In R15 multi-core, the Ultra 9 386H scores 3223 versus 2572, a 25.3% win. In R20 multi-core, it leads 12820 to 10717, a 19.6% margin. Yet in R23 multi-core, the tables turn completely: the Core 7 251TE scores 25518 versus 20547, a 19.5% victory for the desktop chip. This inconsistency across Cinebench versions is unusual and suggests that the two processors have very different scaling behaviors under sustained multi-core loads.

Single-core results are also split. In Cinebench R15 single-core, the Core 7 251TE wins 362 to 303.5, a 16.2% margin. In R20 single-core, the Ultra 9 386H wins 1809 to 1512, a 19.6% margin. Then in R23 single-core, the Core 7 251TE dominates with 3602 versus 2071.5, a 42.5% advantage. That R23 single-core number for the Core 7 251TE is remarkable and indicates a very high boost capability in lightly threaded work.

PassMark multi-thread and physics tests favor the Ultra 9 386H. In PassMark multi-thread, it scores 35399 versus 30022, a 17.9% win. In physics, it posts 3028 against 1938, a 56.2% advantage. Floating point math also goes to the Ultra 9 386H, 108527 to 85607, a 26.8% lead. Data encryption and compression both favor the Ultra 9 386H, with 22.4% and 5.4% margins respectively.

The one area where the Core 7 251TE scores a decisive win in PassMark is integer math. It scores 125739 versus 87284 for the Ultra 9 386H, a 30.6% advantage. This is the single largest PassMark win for the Core 7 251TE and shows where its architecture excels.

The Verdict

The data supports two very different use cases. The Intel Core Ultra 9 386H is the better all-round performer, with wins in 13 of 17 benchmarks. Its strengths are in physics, floating point math, encryption, and extended instructions. The 143.6% lead in find prime numbers and 71.7% lead in extended instructions are the kind of margins that matter for scientific computing, compression workloads, and any task that relies on specialized instruction sets.

The Intel Core 7 251TE is the single-thread champion, particularly in Cinebench R23 where it beats the Ultra 9 386H by 42.5%. Its 30.6% win in integer math also makes it attractive for workloads that are heavily integer-bound, such as certain database operations or legacy application code. The 19.5% win in Cinebench R23 multi-core shows it can sustain high multi-core throughput in that specific rendering workload, despite losing the R15 and R20 multi-core tests.

For a mobile user who needs consistent performance across a wide variety of tasks, the Ultra 9 386H is the clear choice. Its 56.2% lead in physics and 22.4% lead in encryption indicate strong all-core behavior. For a desktop user who prioritizes single-thread responsiveness and integer throughput, the Core 7 251TE is the better fit, despite its lower overall benchmark average.

Specification Differences

The two processors differ substantially in their core configurations. The Core 7 251TE has 24 cores and 32 threads, while the Ultra 9 386H has 16 cores and 16 threads. The Core 7 251TE also has a higher boost clock at 5.40 GHz compared to 4.90 GHz, but a lower base clock at 1.40 GHz versus 2.10 GHz. The thermal design power differs as well: the Core 7 251TE is rated at 45 watts, while the Ultra 9 386H is rated at 25 watts.

Memory support diverges significantly. The Ultra 9 386H supports DDR5 and LPDDR5X memory with a bandwidth of 115.2 GB/s. The Core 7 251TE supports DDR4 and DDR5 with a bandwidth of 89.6 GB/s. The Core 7 251TE also supports ECC memory, while the Ultra 9 386H does not.

PCIe lanes differ: the Core 7 251TE provides Gen 5 with 16 lanes (CPU only), while the Ultra 9 386H provides Gen 5 with 12 lanes (CPU only). The socket is different as well: the Ultra 9 386H uses Intel BGA 2540, while the Core 7 251TE uses Intel Socket 1700. The market segments are mobile for the Ultra 9 386H and desktop for the Core 7 251TE.

Cache hierarchies are very different. The Ultra 9 386H has 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. The Core 7 251TE has 80 KB L1 per core, 1.25 MB L2 per core, and 36 MB shared L3. The integrated graphics differ: the Ultra 9 386H uses Intel Xe3 Graphics, while the Core 7 251TE uses UHD Graphics 770. The Core 7 251TE has a die size of 215 mm², while the Ultra 9 386H has no recorded die size.

Architecture Differences

The Ultra 9 386H is built on Panther Lake architecture using a 3 nm process node from Intel. It is part of the Core Ultra Series 3 and the Ultra 9 (Panther Lake-H) generation. The Core 7 251TE uses Bartlett Lake architecture on a 10 nm process node, part of the Core 7 (Bartlett Lake) generation. Both are manufactured by Intel.

The core counts and threading models differ fundamentally. The Ultra 9 386H has 16 cores and 16 threads, meaning no hyperthreading. The Core 7 251TE has 24 cores and 32 threads, indicating hyperthreading is enabled. This explains why the Core 7 251TE can win in certain multi-threaded workloads despite the Ultra 9 386H's superior per-core performance in most tests.

The L3 cache is double on the Core 7 251TE, 36 MB shared versus 18 MB shared. This larger cache likely contributes to its strong Cinebench R23 performance. The L1 and L2 caches are larger per core on the Ultra 9 386H, which may explain its wins in physics and floating point math. The foundry is the same for both, Intel, but the process nodes are generations apart.

The release dates differ by about a year, with the Core 7 251TE released in January 2025 and the Ultra 9 386H in January 2026. The production status is active for both. Neither processor has an unlocked multiplier. The Core 7 251TE has a launch MSRP of $384, while the Ultra 9 386H has no recorded launch MSRP.

Where Each One Wins

The Intel Core Ultra 9 386H is the winner for mobile users who need a balanced processor that handles a wide range of tasks well. Its 25.3% lead in Cinebench R15 multi-core and 19.6% lead in R20 multi-core show strong all-core performance in older render tests. The 56.2% advantage in PassMark physics makes it ideal for simulation and physics-heavy applications. The 22.4% lead in data encryption and 26.8% lead in floating point math make it suitable for security software and scientific computing. The 143.6% lead in find prime numbers and 71.7% lead in extended instructions are decisive for workloads that use SIMD or specialized instructions.

The Intel Core 7 251TE is the winner for desktop users who care about single-thread performance and integer throughput. Its 42.5% lead in Cinebench R23 single-core is the largest single-core margin recorded between these two chips. The 30.6% lead in integer math makes it better for integer-bound applications like certain compilers, database engines, and legacy software. The 19.5% win in Cinebench R23 multi-core shows it can still deliver competitive multi-threaded rendering performance when the workload scales with its 24 cores and 32 threads.

The data also shows the Ultra 9 386H wins in PassMark multi-thread by 17.9%, so for general multi-threaded productivity, the Ultra 9 386H is ahead. However, the Core 7 251TE has ECC memory support, which the Ultra 9 386H lacks, making it the only option for error-correcting memory configurations. The Core 7 251TE also has more PCIe lanes (16 versus 12) and a larger L3 cache (36 MB versus 18 MB), which may matter for certain storage or expansion configurations.

In summary, the Ultra 9 386H wins the majority of benchmarks and is the better general-purpose mobile processor. The Core 7 251TE wins the single-thread and integer-specific contests and is the better choice for desktop workloads that favor those characteristics. The average benchmark scores are close, but the distribution of wins is not.
