The data indicates that the Intel part is the clear performance leader, but the AMD part holds specific advantages in platform features.

FAQ

Q: Which processor has more cores and threads?

A: The Intel Core Ultra 5 235H has 14 cores and 14 threads, while the AMD Ryzen AI Embedded P132 has 6 cores and 12 threads. This core count difference is a primary driver of the Intel part’s large lead in multithreaded workloads.

Q: How do their single-threaded performance scores compare?

A: In the PassMark single-thread test, the Intel Core Ultra 5 235H scores 4359, which is 14.8% higher than the AMD Ryzen AI Embedded P132’s score of 3713. The Intel part also has a higher boost clock of 5.00 GHz compared to 4.50 GHz on the AMD chip.

Q: What is the difference in L3 cache capacity?

A: The Intel Core Ultra 5 235H has 18 MB of shared L3 cache, whereas the AMD Ryzen AI Embedded P132 has only 4 MB of L3 cache. This disparity is significant for workloads that rely on large, frequently accessed data sets.

Q: Do both processors support ECC memory?

A: No. The AMD Ryzen AI Embedded P132 supports ECC memory, while the Intel Core Ultra 5 235H does not. This makes the AMD part more suitable for embedded or server-like environments where data integrity is critical.

Q: Which processor has a higher average benchmark score?

A: The AMD Ryzen AI Embedded P132 has a higher average benchmark score of 37804, compared to the Intel Core Ultra 5 235H’s 37522. Despite this, the Intel part wins every individual head-to-head benchmark test listed.

Q: How do the processors compare in terms of PCIe generation support?

A: The Intel Core Ultra 5 235H supports PCIe Gen 5 with 8 CPU lanes, while the AMD Ryzen AI Embedded P132 supports PCIe Gen 4 with 14 CPU lanes. The Intel part has the newer standard, but the AMD part offers more lanes for direct CPU connectivity.

Architecture Differences

The architectural divide between these two processors is stark, starting with the core design. The AMD Ryzen AI Embedded P132 uses the Gorgon Point codename and is built on the Ryzen AI Embedded generation, which employs a mix of Zen 5 and Zen 5c cores. It has 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. In contrast, the Intel Core Ultra 5 235H is based on the Arrow Lake-H codename and the Core Ultra Series 2 generation, using a 14-core, 14-thread configuration with a base clock of 2.40 GHz and a boost clock of 5.00 GHz. The Intel part does not support simultaneous multithreading, which explains why its thread count equals its core count.

The cache hierarchy is a major differentiator. The AMD chip provides 80 KB of L1 and 1 MB of L2 per core, with a modest 4 MB of shared L3 cache. The Intel chip provides 192 KB of L1 and 3 MB of L2 per core, with a much larger 18 MB of shared L3 cache. This gives the Intel part a substantial advantage in cache capacity, which directly contributes to its superior performance in data-heavy and multi-threaded tasks. The manufacturing processes also differ: the AMD part is fabricated on TSMC’s 4 nm node, while the Intel part is on TSMC’s 3 nm node, with the latter process generally enabling higher clock speeds and better power efficiency.

Memory and I/O features also diverge. Both support DDR5 and LPDDR5X memory, but the Intel part has a higher memory bandwidth of 102.4 GB/s versus 89.6 GB/s for the AMD part. The AMD chip supports ECC memory, a feature absent from the Intel chip. For expansion, the AMD part offers PCIe Gen 4 with 14 CPU lanes, while the Intel part offers the newer PCIe Gen 5 with only 8 CPU lanes. The integrated graphics differ as well: the AMD part features Radeon 840M, while the Intel part features Arc Graphics 140T. Finally, the release dates show the Intel part launched earlier, with a release date of January 2025, while the AMD part is scheduled for March 2026.

The Verdict

The data is unambiguous: the Intel Core Ultra 5 235H is the superior performer in every benchmark test. It wins all 11 head-to-head comparisons, with decisive margins in floating-point math (54.8% ahead), encryption (50.5% ahead), and multithreaded performance (36.0% ahead). For users prioritizing raw compute speed, multi-core workloads, or single-thread responsiveness, the Intel processor is the clear choice. Its 14 cores and 18 MB of L3 cache provide a structural advantage that the AMD part cannot overcome, despite the AMD chip’s higher average benchmark score (37804 vs 37522).

However, the AMD Ryzen AI Embedded P132 should not be dismissed outright. Its support for ECC memory is a critical feature for embedded systems, industrial controllers, or any application where memory error correction is non-negotiable. The AMD part also has more PCIe Gen 4 lanes (14 vs 8), which can be beneficial for systems requiring extensive I/O connectivity. The data suggests that the AMD processor is not a performance competitor but rather a specialized part for reliability-focused use cases. The Intel part is for those who need speed; the AMD part is for those who need stability and error resilience.

Head-to-Head Benchmarks

The head-to-head benchmark data is entirely one-sided. The Intel Core Ultra 5 235H wins every single test, with the AMD Ryzen AI Embedded P132 trailing by significant margins. The largest delta is in the PassMark find prime numbers test, where Intel scores 239 versus AMD’s 57, a 76.2% deficit for the AMD part. This suggests a massive advantage in integer-heavy, single-threaded algorithmic workloads for the Intel chip.

In floating-point math, the Intel part scores 93509, which is 54.8% ahead of the AMD part’s 42248. This indicates that the Intel processor is far more capable in scientific computing and simulation tasks. The data encryption test shows Intel at 23121 versus AMD at 11444, a 50.5% lead, highlighting Intel’s superiority in security-related workloads. The multithread score of 30091 for Intel versus 19262 for AMD is a 36.0% difference, which is expected given the core count disparity.

The smaller margins are still notable. In integer math, Intel leads by 16.2% (74247 vs 62249). In random string sorting, Intel leads by 30.5% (36208 vs 25181). The single-thread score sees Intel at 4359 versus AMD at 3713, a 14.8% difference. Even in data compression, which often favors different architectures, Intel wins with 301979 versus 230437, a 23.7% margin. The physics test shows Intel at 1985 versus AMD at 1022, a 48.5% gap. Across all tests, the average benchmark score for the AMD part is 37804, which is actually slightly higher than Intel’s 37522, but this is a statistical anomaly that does not reflect the performance reality in any of the specific tests.

Where Each One Wins

Based strictly on the benchmark results, the Intel Core Ultra 5 235H is the winner in every measurable performance category. It excels in multi-threaded workloads, as evidenced by its 36.0% lead in the multithread test and its 48.5% lead in the physics test. It also dominates in single-threaded tasks, with a 14.8% advantage in the single-thread test. For encryption and data security, the Intel part is substantially faster, with a 50.5% lead. For floating-point operations, typical of engineering or scientific simulations, it is 54.8% faster. There is no performance domain where the AMD Ryzen AI Embedded P132 wins.

The AMD part’s strengths are not in benchmark scores but in platform features. The support for ECC memory is the most significant differentiator, making it the only viable choice for systems that require error-correcting memory. The AMD part also provides more PCIe Gen 4 lanes (14 vs 8), which is advantageous for connecting multiple NVMe drives or other high-bandwidth peripherals. The AMD part has a slightly higher average benchmark score (37804) than the Intel part (37522), but this is an aggregate metric that does not reflect a win in any specific test. For a user who must have ECC memory or needs maximum I/O lane count, the AMD processor is the only option. For every other use case, the Intel processor is the superior performer.
