AMD Ryzen AI 5 PRO 435G vs Intel Core Ultra 5 235H Comparison

The AMD Ryzen AI 5 PRO 435G and the Intel Core Ultra 5 235H occupy different corners of the processor market, and the benchmark data reflects that split clearly. The Intel part wins every single head-to-head test recorded in the database, taking all 11 comparisons. The AMD part, however, is a desktop processor with a 65 TDP, while the Intel part is a mobile processor with a 28 TDP. The data shows a consistent performance advantage for Intel in raw compute, but the platform and efficiency differences matter for anyone choosing between them.

Where Each One Wins

The Intel Core Ultra 5 235H wins in every recorded benchmark category. The database lists 11 head-to-head comparisons, and Intel takes all 11. There is no test in the shared set where the AMD Ryzen AI 5 PRO 435G comes out ahead. The Intel processor leads in data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded workloads, physics calculations, random string sorting, and single-threaded performance.

The AMD Ryzen AI 5 PRO 435G still has a place in the database, but its wins are not in the head-to-head column. It posts a higher average benchmark score of 40718 compared to Intel's 37522, which puts it in the 87th percentile of all CPUs versus Intel's 85th percentile. The AMD part also has a higher PassMark multithread score relative to its core count, and its nearest rivals in the database include Intel Xeon and Core series parts with similar average scores. The AMD processor's advantage is in its overall average, not in the direct comparison with the Intel Core Ultra 5 235H.

For workloads where the Intel processor's strengths are not the primary concern, the AMD part remains competitive. The data shows the AMD part delivers a single-thread score of 3829 and a multithread score of 20285, which are respectable numbers even if they lag the Intel part's 4359 and 30091 respectively. The AMD part's 4 MB of L3 cache and 6 cores with 12 threads suggest it targets lighter, more power-conscious desktop builds, while the Intel part's 14 cores and 18 MB of L3 cache target heavier mobile workloads.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 5 PRO 435G uses the Gorgon Point codename and belongs to the Ryzen AI PRO 400 generation built on Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC. The Intel Core Ultra 5 235H uses the Arrow Lake architecture with the Arrow Lake-H codename, part of the Core Ultra Series 2 generation, and is built on a 3 nm process, also at TSMC.

Core counts differ significantly. The AMD part has 6 cores and 12 threads, while the Intel part has 14 cores and 14 threads. The Intel part does not use simultaneous multithreading, so its thread count equals its core count. The AMD part relies on SMT to double its thread count from 6 to 12. This structural difference explains much of the multithreaded performance gap, though not all of it.

Cache hierarchies are also different. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. The Intel part has 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. The Intel part's larger caches, especially the 18 MB shared L3, give it a substantial advantage in workloads that benefit from repeated data access.

Memory support differs as well. The AMD part supports DDR5 only, while the Intel part supports both DDR5 and LPDDR5X. Both use dual-channel memory buses, but the Intel part has a higher memory bandwidth at 102.4 GB/s compared to the AMD part's 89.6 GB/s. The AMD part supports ECC memory, which the Intel part does not. The AMD part uses PCIe Gen 4 with 10 lanes, while the Intel part uses PCIe Gen 5 with 8 lanes. The AMD part is a desktop processor on AMD Socket AM5, while the Intel part is a mobile processor on Intel BGA 2049.

Clock speeds favor Intel. The AMD part has a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The Intel part has a base clock of 2.40 GHz and a boost clock of 5.00 GHz. The Intel part also has a much lower TDP of 28 watts versus the AMD part's 65 watts, which is notable given its higher performance in the benchmarks.

Head-to-Head Benchmarks

The largest margin comes in the prime number finding test. The Intel Core Ultra 5 235H scores 239 against the AMD part's 55, a delta of -77 percent, meaning the AMD part is 77 percent behind. This is an enormous gap and likely reflects both the core count difference and the Intel part's higher boost clock.

Floating point math shows a similar pattern. Intel scores 93509 against AMD's 43494, a delta of -53.5 percent. The Intel part is more than twice as fast in this test. Data encryption shows Intel at 23121 versus AMD's 12111, a delta of -47.6 percent. Physics calculations follow with Intel at 1985 versus AMD's 999, a delta of -49.7 percent.

Multithreaded performance is a major differentiator. Intel scores 30091 against AMD's 20285, a delta of -32.6 percent. This is expected given the Intel part has 14 cores versus 6, but the margin is still substantial. Random string sorting shows Intel at 36208 versus AMD's 27407, a delta of -24.3 percent. Extended instructions show Intel at 23354 versus AMD's 18697, a delta of -19.9 percent.

The smaller gaps are still consistent. Data compression shows Intel at 301979 versus AMD's 253484, a delta of -16.1 percent. Integer math shows Intel at 74247 versus AMD's 63707, a delta of -14.2 percent. Single-threaded performance shows the closest margin, with Intel at 4359 versus AMD's 3829, a delta of -12.2 percent. Even in the narrowest gap, the Intel part remains clearly ahead.

The database also records Cinebench results for the Intel part only. It scores 2580 in Cinebench R15 multicore, 364 in R15 single-core, 10751 in R20 multicore, 1517 in R20 single-core, 25598 in R23 multicore, and 3613 in R23 single-core. These numbers provide additional context for the Intel part's compute capabilities but do not change the head-to-head picture.

The Verdict

The data supports choosing the Intel Core Ultra 5 235H for anyone who needs maximum raw performance in the recorded benchmarks. It wins every head-to-head test, often by large margins. The 14-core configuration with a 5.00 GHz boost clock delivers consistently higher scores across compression, encryption, math, sorting, physics, and single-threaded workloads. The Intel part also does this at a lower TDP of 28 watts, which is remarkable for a mobile processor.

The AMD Ryzen AI 5 PRO 435G suits a different profile. It is a desktop part with a 65 watt TDP, ECC memory support, and AMD Socket AM5 compatibility. Its overall average benchmark score of 40718 and 87th percentile ranking are higher than the Intel part's 37522 and 85th percentile, but that average includes different benchmark sets. In the direct comparisons, the AMD part trails. The AMD part's 6 cores and 12 threads with a 4.50 GHz boost clock make it a lighter option, and its 4 MB L3 cache is much smaller than Intel's 18 MB.

For desktop builders who value ECC memory and a lower core count with fewer threads, the AMD part offers a viable path. For mobile users or anyone prioritizing compute throughput, the Intel part is the clear choice from the recorded data. The Intel part's advantages in memory bandwidth, cache size, clock speed, and core count all contribute to its sweep of the head-to-head benchmarks.
