Intel Core 9 270H vs Intel Core Ultra 5 235T Comparison

The Intel Core Ultra 5 235T and the Intel Core 9 270H are two very different interpretations of the modern Intel CPU. The 235T is a desktop Arrow Lake part built on a 3 nm process, while the 270H is a mobile Raptor Lake-H part on a 10 nm process. Despite their architectural divergence, their average benchmark scores are remarkably close: the 235T scores 38561, while the 270H scores 38335, a delta of just 0.6%. This positions them as direct competitors in overall capability, but the data reveals they achieve this parity through entirely different strengths.

Head-to-Head Benchmarks

The most striking result in the entire comparison is the Cinebench R23 single-core test. The Core Ultra 5 235T scores 3703, while the Core 9 270H manages only 2040. This is an 81.5% delta, making it the single largest victory for either processor in any test. This massive gap is not an outlier in Cinebench; the 235T also leads by 7.5% in R15 single-core (373 vs 347) and by 7.3% in R20 single-core (1555 vs 1449). The data consistently shows that the 235T’s Arrow Lake architecture delivers a substantially stronger single-threaded performance profile.

The multi-core results are more nuanced but still favor the 235T. In Cinebench R23 multi-core, the 235T scores 26232, which is a 45.7% advantage over the 270H’s 18000. However, this lead shrinks significantly in older Cinebench versions: in R20 multi-core, the 235T leads by 7.3% (11017 vs 10268), and in R15 multi-core, the lead is also 7.3% (2644 vs 2464). The PassMark multi-thread test shows a similar 7.5% lead for the 235T (30918 vs 28764). This pattern suggests that the 235T’s advantage in multi-threaded workloads becomes more pronounced in newer, more demanding benchmarks.

Looking at specialized workloads, the 235T dominates in several areas. In PassMark floating-point math, it scores 106546, which is 50.8% higher than the 270H’s 70640. The 235T also excels in extended instructions, leading by 15.6% (23212 vs 20079), and in data encryption, where it leads by 21.1% (23457 vs 19369). The most extreme difference outside of Cinebench is in the find prime numbers test, where the 235T scores 318 versus the 270H’s 112, a staggering 183.9% delta.

However, the Core 9 270H does have its own victories. The most significant is in PassMark data compression, where it scores 333785, beating the 235T’s 295100 by 11.6%. It also wins in integer math, scoring 97654 versus 84244, a 13.7% advantage for the 270H. Finally, it edges out the 235T in random string sorting, 36867 vs 35377, a 4% delta. These three wins are notable because they demonstrate that the 270H’s higher thread count (20 vs 14) can be leveraged effectively in specific, integer-heavy or data-manipulation tasks.

In terms of overall victory count, the 235T wins 14 of the 17 head-to-head benchmarks, while the 270H wins 3. The magnitude of the 235T’s wins is also generally larger, particularly in the R23 and floating-point tests. The 270H’s wins are narrower, with its largest being the 11.6% data compression victory. This asymmetry in both frequency and magnitude of wins points to a clear overall performance advantage for the 235T, despite the close average scores.

The Verdict

The data presents a clear choice for different use cases. The Intel Core Ultra 5 235T is the superior processor for anyone prioritizing raw computational throughput, especially in floating-point, encryption, and modern multi-threaded workloads. Its 50.8% lead in floating-point math and 45.7% lead in Cinebench R23 multi-core make it the obvious pick for content creation, 3D rendering, and scientific computing. Its single-core dominance, as shown by the 81.5% lead in R23 single-core, also makes it the better choice for general desktop responsiveness and lightly-threaded applications.

The Intel Core 9 270H, while losing the majority of tests, is not without merit. Its 11.6% lead in data compression and 13.7% lead in integer math indicate that it is better suited for specific workloads like file archiving, database operations, or any task that relies heavily on integer arithmetic. Its 20 threads provide a theoretical advantage in highly parallel integer tasks, which the benchmark results confirm. However, this advantage is narrow and does not compensate for the 235T’s overwhelming lead in most other areas.

For a desktop user building a workstation, the choice is clear: the Intel Core Ultra 5 235T is the better processor. It is faster in the majority of tests and offers a significantly stronger all-around performance profile. For a mobile user who needs a processor for a laptop, the Core 9 270H is the only option of the two, given its BGA 1744 socket and mobile market segment. But if the comparison is purely about performance capability, the data overwhelmingly favors the 235T, despite the 270H’s higher launch MSRP of $697.

Architecture Differences

The two processors are built on fundamentally different architectures from different foundries. The Intel Core Ultra 5 235T uses the Arrow Lake architecture, specifically the Arrow Lake-S codename, and is fabricated by TSMC on a 3 nm process node. It belongs to the Core Ultra Series 2 generation and is described as “Ultra 5 (Arrow Lake)”. In contrast, the Intel Core 9 270H uses the Raptor Lake architecture, with the codename Raptor Lake-H, and is fabricated by Intel on a 10 nm process. It belongs to the “Core 9 (Raptor Lake Refresh)” generation.

These architectural differences manifest in their physical characteristics. The 235T has a die size of 243 mm² and contains 17,800 million transistors. The 270H’s die size and transistor count are not listed in the data. The cache structures also differ significantly. The 235T has a larger L1 cache of 192 KB per core and an L2 cache of 3 MB per core, while the 270H has 80 KB per core and 2 MB per core, respectively. Both share the same 24 MB shared L3 cache.

The integrated graphics also differ. The 235T features Arc Xe-LPG Graphics with 24 execution units (EU), while the 270H features Iris Xe Graphics with 96 EU. This suggests the 270H has a more powerful integrated GPU, though the benchmark data does not include graphics tests. The memory support also differs: the 235T supports only DDR5, while the 270H supports both DDR4 and DDR5. The 235T also has a wider PCIe implementation, with Gen 5 and 20 lanes (CPU only), versus the 270H’s Gen 5 and 8 lanes (CPU only).

Specification Differences

The specification sheets for these two processors show several key differences beyond their architecture. The most obvious is the core count and threading: both have 14 cores, but the 235T has 14 threads (no hyperthreading), while the 270H has 20 threads. The 270H has higher clock speeds, with a base clock of 2.70 GHz and a boost clock of 5.80 GHz, compared to the 235T’s 2.20 GHz base and 5.00 GHz boost. However, the 235T has a higher TDP of 65 watts, versus the 270H’s 45 watts.

The sockets differ entirely: the 235T uses Intel Socket 1851 for desktop, while the 270H uses Intel BGA 1744 for mobile. The 235T has a memory bandwidth of 102.4 GB/s, while the 270H’s bandwidth is not listed. The 235T has a launch MSRP of $247, while the 270H has a launch MSRP of $697. The release dates also differ, with the 235T released on 2025-01-06 and the 270H on 2024-12-17. Finally, their part numbers are SRQES for the 235T and SRQ6V for the 270H.

It is also superior for 3D rendering and video encoding, given its 45.7% lead in Cinebench R23 multi-core and 7.3% lead in R20 multi-core. Its 21.1% lead in data encryption makes it preferable for security-focused applications. Furthermore, its 15.6% lead in extended instructions makes it a better fit for developers compiling code or using advanced SIMD operations. Its single-core dominance also makes it the better choice for general desktop use, web browsing, and office productivity.

The Intel Core 9 270H has a narrow but distinct set of strengths. It is the better choice for file compression and decompression tasks, as indicated by its 11.6% lead in PassMark data compression. It is also the better option for integer-heavy workloads such as database management, financial calculations that avoid floating-point, and certain types of cryptography that rely on integer operations, given its 13.7% lead in PassMark integer math. Its slight 4% lead in random string sorting suggests it may be slightly better in some data-processing and sorting algorithms. For a user whose primary workload involves these specific integer or compression tasks, the 270H offers a tangible advantage, but this comes at the cost of significant performance losses in nearly every other benchmark category.
