AMD Ryzen AI 5 PRO 435 vs Intel Core 5 120U Comparison

The AMD Ryzen AI 5 PRO 435 and Intel Core 5 120U are both mobile processors aimed at thin-and-light laptops, but the benchmark data reveals a stark performance disparity. The AMD chip, built on a newer 4 nm process with Zen 5 architecture, dominates the Intel part, which uses an older 10 nm Raptor Lake design. The head-to-head results show a clean sweep: the Ryzen AI 5 PRO 435 wins all 11 recorded benchmark comparisons, with victories ranging from a narrow 6.2% margin to a commanding 79.8% lead. This analysis breaks down the specific workloads where each processor holds an advantage, examines the architectural choices behind the scores, and determines which user should prioritize which chip based strictly on the recorded data.

Head-to-Head Benchmarks

The most lopsided result in the comparison comes from the PassMark extended instructions test, where the AMD Ryzen AI 5 PRO 435 scores 16,724 against the Intel Core 5 120U’s 9,299. That is a 79.8% advantage for AMD, indicating a massive lead in workloads that leverage advanced CPU instruction sets, such as cryptography, signal processing, and certain scientific computations. This single result underscores the generational leap in the AMD core design.

In data compression, the Ryzen AI 5 PRO 435 delivers 232,803 points versus 166,432 for the Intel part, a 39.9% win. This is a significant margin for a real-world task like file archiving or database operations. Random string sorting shows a similar pattern, with AMD scoring 24,936 and Intel 19,060, giving AMD a 30.8% lead. These two tests suggest the AMD processor is substantially better at memory-intensive sorting and data manipulation tasks.

Multi-threaded performance, a key metric for productivity, shows the Ryzen AI 5 PRO 435 scoring 19,091 against Intel’s 15,042, a 26.9% advantage. This is despite both processors having 12 threads, meaning the AMD chip’s efficiency-per-thread is markedly higher. Integer math follows with AMD at 60,879 and Intel at 52,280, a 16.4% lead, while floating-point math sees AMD at 41,114 versus Intel’s 36,026, a 14.1% win. These results confirm that AMD’s lead extends across both integer and floating-point arithmetic.

The single-thread test is closer but still favors AMD: 3,757 points against Intel’s 3,479, an 8% difference. This margin is notable because the Intel chip has a higher boost clock (5.00 GHz versus 4.50 GHz), yet still loses on single-core performance, suggesting the Zen 5 architecture provides superior instructions-per-clock. Data encryption shows AMD ahead by 7.8% (11,267 versus 10,453), and prime number finding sees AMD at 57 versus 53, a 7.5% edge. Physics simulation rounds out the sweep with AMD at 995 versus Intel’s 937, a 6.2% win.

Where Each One Wins

Given the clean sweep for AMD, the analysis of "where each one wins" is straightforward: the Ryzen AI 5 PRO 435 wins every single recorded workload. There is no benchmark in the database where the Intel Core 5 120U comes out ahead. The closest Intel gets is in the physics test and prime number finding, where the margins are under 8%, but these are still losses.

The AMD processor’s largest wins are in extended instructions (79.8%), data compression (39.9%), and random string sorting (30.8%). These are heavily parallel or specialized workloads that benefit from the newer architecture and efficient cache design. The Intel chip’s smallest deficits are in physics (6.2%), prime numbers (7.5%), and encryption (7.8%), which are workloads that may rely more on raw clock speed or specific execution units where the Raptor Lake design is less disadvantaged.

For a user, this means the Ryzen AI 5 PRO 435 is the better choice for virtually any compute-intensive task, from software compilation to media encoding to complex spreadsheet calculations. The Intel Core 5 120U does not have a single stronghold where it can claim a performance win. Its only potential advantage lies outside raw performance, such as its lower 15 W TDP, which could be a factor in fanless designs or extreme battery-life optimization, though the database does not provide battery life metrics.

Architecture Differences

The two processors come from different design philosophies and manufacturing generations. The AMD Ryzen AI 5 PRO 435 uses the Zen 5 architecture on a 4 nm TSMC process node, while the Intel Core 5 120U uses the Raptor Lake architecture on Intel’s 10 nm process. This process difference is a primary driver of the performance gap, as the smaller node allows for higher efficiency and lower power draw per transistor.

Core counts differ significantly. The AMD chip has 6 physical cores and 12 threads, while the Intel chip has 10 cores and 12 threads. Intel achieves the same thread count using a hybrid design (likely a mix of performance and efficiency cores, though the database does not specify the exact mix), but the AMD chip’s 6 full Zen 5 cores prove more capable in every recorded test. The L3 cache also favors Intel in total size: the Core 5 120U has 12 MB of shared L3 cache, whereas the Ryzen AI 5 PRO 435 has only 4 MB. Despite the smaller cache, AMD wins the cache-sensitive workloads like compression and sorting, suggesting that the Zen 5 memory subsystem is more efficient or that the L2 cache (1 MB per core on AMD versus 1.25 MB per core on Intel) compensates.

Memory support differs: the AMD chip supports DDR5 and LPDDR5X with a recorded bandwidth of 89.6 GB/s, while the Intel chip supports DDR4 and DDR5 but has no recorded bandwidth figure. The AMD chip also supports ECC memory, a feature absent on the Intel part. PCIe lanes favor AMD with 14 Gen 4 lanes (CPU only) versus Intel’s 8 Gen 4 lanes, which could impact expansion options for high-speed storage or external GPUs.

The integrated graphics also differ: AMD uses the Radeon 840M, while Intel uses Iris Xe Graphics 80EU. The database does not provide GPU benchmark scores, so no performance conclusion is drawn here. The AMD chip has a base clock of 2.00 GHz and boost of 4.50 GHz, while the Intel chip has a lower base of 1.40 GHz but a higher boost of 5.00 GHz. The AMD chip’s TDP is 28 W, while the Intel chip is rated at 15 W, indicating Intel’s design is more power-efficient on paper, though the performance data shows AMD is far more efficient per unit of work.

The Verdict

Based strictly on the recorded benchmark data, the AMD Ryzen AI 5 PRO 435 is the superior processor for every tested workload. It holds a 26.9% lead in multi-threaded performance and an 8% lead in single-threaded performance, meaning it will be faster in both heavily parallel tasks and light, latency-sensitive applications. The 79.8% advantage in extended instructions makes it the clear choice for developers, researchers, or anyone running niche SIMD-heavy code.

The Intel Core 5 120U’s only quantitative advantage is its 15 W TDP, which is 13 W lower than the AMD chip’s 28 W. This could make it a better fit for ultra-portable designs where thermal output is a hard constraint, but the performance cost is severe. The Intel chip also has a higher boost clock (5.00 GHz versus 4.50 GHz) and more L3 cache (12 MB versus 4 MB), yet these advantages do not translate into any benchmark win.

For a user who prioritizes raw performance in a mobile workstation or a high-end consumer laptop, the Ryzen AI 5 PRO 435 is the only logical choice based on the data. For a user who needs the absolute lowest power draw and does not require peak performance, the Intel chip is the only option in this comparison, but the database shows no scenario where it outperforms the AMD part.
