Intel Core 7 250H vs Intel Core Ultra 7 270K Plus Comparison

The Intel Core Ultra 7 270K Plus dominates the Intel Core 7 250H across every recorded benchmark, with the desktop part winning all 17 head-to-head comparisons. The Core 7 250H, a mobile processor, trails by margins ranging from 15.8% to 82.8% depending on the workload, with the largest deficits appearing in specialized compute tasks.

Head-to-Head Benchmarks

The most decisive victory for the Core Ultra 7 270K Plus comes in PassMark's find prime numbers test, where it scores 615 against 106 for the Core 7 250H, a delta of 82.8%. This indicates a massive advantage in integer-heavy mathematical workloads. Similarly, PassMark extended instructions shows an 72.7% gap, with scores of 63506 and 17318 respectively, demonstrating the desktop chip's superior execution of advanced instruction sets.

Multi-core rendering benchmarks tell a consistent story. In Cinebench R23 multicore, the Core Ultra 7 270K Plus scores 44253 versus 16561, a 62.6% advantage. Cinebench R20 multicore shows a 60.4% gap (24461 vs 9697), while Cinebench R15 multicore records a 52.7% difference (6656 vs 3147). These results confirm that the 270K Plus delivers roughly 2.5 to 2.7 times the multi-threaded rendering performance of the 250H across all three Cinebench versions.

Single-core performance favors the desktop chip as well, though by a smaller margin. In Cinebench R23 singlecore, the 270K Plus scores 2439 against 1931, a 20.8% lead. Cinebench R20 singlecore shows a 60.4% gap (3453 vs 1368), while Cinebench R15 singlecore records a 15.8% advantage (354 vs 298). PassMark single thread confirms the trend with a 18.2% delta (5068 vs 4148).

Data processing workloads follow the same pattern. PassMark data compression shows the 270K Plus at 804322 versus 303269, a 62.3% lead. Data encryption results are even more lopsided: 59097 versus 18206, a 69.2% gap. Floating point math favors the desktop part by 71.6% (229491 vs 65094), while integer math shows a smaller but still substantial 43.7% advantage (175986 vs 99100).

Overall throughput metrics reinforce the hierarchy. PassMark multithread gives the 270K Plus 68574 points against 27030 for the 250H, a 60.6% delta. PassMark physics shows a 55.1% gap (4064 vs 1824), and random string sorting records a 64.8% difference (96945 vs 34136). The average benchmark score for the 270K Plus is 93785, placing it in the 96th percentile of all CPUs, while the 250H averages 35728, good for the 85th percentile.

Architecture Differences

The two processors represent fundamentally different design generations. The Core 7 250H is built on Intel's Raptor Lake architecture, specifically the Raptor Lake-H refresh, using a 10 nm process node fabricated by Intel. The Core Ultra 7 270K Plus belongs to the Arrow Lake Refresh family, built on a 3 nm node manufactured by TSMC. This process advantage contributes to the desktop chip's higher transistor count of 17,800 million, while the mobile part's transistor count is not recorded.

Core counts differ significantly. The 250H provides 14 cores and 20 threads, while the 270K Plus offers 24 cores and 24 threads. The desktop processor's lack of hyper-threading on its additional cores explains the equal core and thread counts. Base clocks are 2.50 GHz for the mobile part and 3.70 GHz for the desktop part, with boost clocks of 5.40 GHz and 5.50 GHz respectively. The 270K Plus has an unlocked multiplier, a feature absent on the 250H.

Cache hierarchies diverge substantially. The 250H carries 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The 270K Plus has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. These larger cache allocations support the desktop chip's performance advantage in repeated and large dataset workloads.

Memory support marks another split. The 250H supports both DDR4 and DDR5 in a dual-channel configuration, while the 270K Plus supports only DDR5, also dual-channel, with a recorded memory bandwidth of 115.2 GB/s. ECC memory is supported only on the 270K Plus. PCIe connectivity favors the desktop part with Gen 5 and 20 CPU lanes, while the mobile chip offers Gen 5 with 8 CPU lanes.

Integrated graphics differ in branding and execution unit count. The 250H uses Iris Xe Graphics with 96 EUs, while the 270K Plus features Arc Xe-LPG Graphics with 64 EUs. The mobile part's higher EU count suggests a different graphics design philosophy, though no graphics benchmarks are recorded in the database.

The form factors and sockets are entirely distinct. The 250H is a mobile processor on Intel BGA 1744, while the 270K Plus is a desktop processor on Intel Socket 1851. Thermal design power reflects this: the mobile chip is rated at 45 W, the desktop chip at 125 W. Release dates also differ, with the 250H launching in December 2024 and the 270K Plus in March 2026.

Where Each One Wins

The Intel Core Ultra 7 270K Plus wins in every recorded benchmark category. Its strengths are most pronounced in parallel compute tasks: Cinebench R23 multicore shows a 62.6% lead, PassMark multithread shows 60.6%, and floating point math shows 71.6%. The largest advantage appears in prime number finding at 82.8%, indicating exceptional integer arithmetic capability. Data encryption performance is 69.2% higher, making the desktop part well suited for security-related workloads.

The Core 7 250H's smallest deficits appear in single-threaded tests. PassMark single thread trails by 18.2%, and Cinebench R15 singlecore trails by 15.8%. These are still losses, but they indicate that the mobile chip's per-core efficiency is relatively closer to the desktop part than its multi-core performance. The 250H's 96 EU integrated graphics exceed the 270K Plus's 64 EUs, suggesting a potential graphics advantage, though no graphics benchmarks are recorded in the database to confirm this.

The 270K Plus also offers practical advantages beyond raw speed. Its 20 PCIe Gen 5 lanes support more expansion devices at high bandwidth, and ECC memory support suits error-sensitive environments. The unlocked multiplier permits user-controlled overclocking, which the 250H cannot offer. The desktop chip's higher TDP of 125 W, while consuming more power, enables sustained performance in workloads that the 45 W mobile part cannot maintain.

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 7 270K Plus outperforms the Intel Core 7 250H in every recorded test. The average benchmark score of 93785 for the 270K Plus versus 35728 for the 250H places the desktop chip in the 96th percentile of all CPUs, while the mobile chip sits in the 85th percentile.

Users requiring maximum multi-threaded throughput, heavy data processing, or extensive mathematical computation should choose the Core Ultra 7 270K Plus. Its 24 cores and 24 threads, combined with 36 MB of L3 cache and a 3 nm TSMC process, deliver leading performance in Cinebench and PassMark workloads. The 125 W TDP and desktop socket make it suitable for desktop systems where power is not constrained.

The Core 7 250H serves a different market segment entirely. As a mobile processor on BGA 1744 with a 45 W TDP, it targets laptops and compact systems. Its 14 cores and 20 threads provide respectable multi-core performance for a mobile part, and its support for DDR4 alongside DDR5 offers memory flexibility. The Iris Xe Graphics with 96 EUs may provide stronger integrated graphics performance than the 270K Plus's 64 EU Arc solution, though this is not confirmed by recorded benchmarks.

For desktop builders prioritizing raw compute, the choice is clear: the Core Ultra 7 270K Plus wins all 17 head-to-head matchups with margins from 15.8% to 82.8%. For mobile users needing a capable processor in a constrained thermal envelope, the Core 7 250H remains the only option of the two, as the 270K Plus cannot be installed in mobile platforms. The data shows no scenario where the Core 7 250H matches the Core Ultra 7 270K Plus in computational performance.
