AMD Ryzen AI 5 435 vs Intel Core Ultra 5 125H Comparison

Head-to-Head Benchmarks

The benchmark data for these two mobile processors tells a fairly clear story: the Intel Core Ultra 5 125H wins the majority of head-to-head tests, taking 10 of the 15 recorded comparisons, while the AMD Ryzen AI 5 435 manages 5 wins. But the margins matter more than the count, and the AMD chip's victories are concentrated in single-threaded workloads, while Intel's are spread across multi-core and specialized tasks.

Starting with the single-core results, the AMD Ryzen AI 5 435 shows a consistent advantage. In Cinebench R15 single-core, it scores 260 against Intel's 241, a 7.3% lead. That gap widens slightly in Cinebench R23 single-core, where AMD scores 1816 versus Intel's 1647.5, a 9.3% margin. The PassMark single-thread test tells the same story: AMD posts 3734 against Intel's 3399, another 9% difference. These are meaningful gaps for lightly threaded applications, and they point to the Zen 5 architecture's strength in per-core efficiency.

The multi-core picture flips decisively in Intel's favor. In Cinebench R15 multi-core, Intel scores 2021.5 against AMD's 1686, a 19.9% advantage. Cinebench R23 multi-core shows a 13% lead for Intel, with 12804.5 versus 11333. The PassMark multithread score follows the trend: Intel at 21100, AMD at 19000, an 11.1% edge. These results reflect Intel's larger core and thread count, which the data shows as 14 cores and 18 threads against AMD's 6 cores and 12 threads.

The most dramatic delta appears in PassMark find prime numbers, where Intel scores 88 against AMD's 58, a 51.7% blowout. This test heavily favors Intel's architecture and core count. Similarly, PassMark physics shows Intel ahead by 33.9%, scoring 1439 versus 1075. Floating-point math also goes Intel's way, with 51670 against 40627, a 27.2% margin. Integer math is closer but still Intel's, 69986 versus 61026, a 14.7% lead.

Data encryption is another strong Intel win, 14251 against 11110, a 28.3% advantage. Data compression is narrower, with Intel at 236209 and AMD at 225374, a 4.8% edge. Random string sorting sees Intel ahead by 10.2%, 27435 versus 24891. The only other AMD win besides the single-core tests is extended instructions, where AMD scores 16197 against Intel's 13749, a 15.1% advantage.

The average benchmark scores from the database place the AMD chip slightly higher overall: 28128 versus 27507. That puts the AMD Ryzen AI 5 435 in the 80th percentile of all CPUs, while Intel sits at the 79th percentile. The nearest rivals for AMD include the Intel Core i5-13490F (0.2% higher) and the Intel Core i5-14500T (0.2% lower), while Intel's closest competitor is the AMD Ryzen 7 5800, which is essentially tied at 0.1% higher. So the overall average is nearly a wash, but the distribution of wins is not.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 5 125H is built on Meteor Lake, a 7 nm process from Intel's own foundry. It uses a hybrid core arrangement, which the data reflects in its 14 cores and 18 threads: a combination of performance and efficiency cores. The L1 cache is listed at 112 KB per core, L2 at 2 MB per core, and L3 at 18 MB shared. The integrated graphics are Arc Xe-LPG with 96 execution units, and the memory support is DDR5 with a dual-channel bus and 89.6 GB/s bandwidth.

The AMD Ryzen AI 5 435, codenamed Gorgon Point, is built on Zen 5 architecture using a 4 nm process from TSMC. It has 6 cores and 12 threads, all of which appear to be full Zen 5 cores based on the data, though the generation listing mentions "Zen 5 / Zen 5c" as a possibility. The cache hierarchy is smaller: 80 KB L1 per core, 1 MB L2 per core, and just 4 MB of L3. The integrated GPU is Radeon 840M. Memory support includes both DDR5 and LPDDR5X, with the same dual-channel 89.6 GB/s bandwidth as Intel. Notably, AMD supports ECC memory while Intel does not.

PCIe capability differs as well. Intel supports PCIe Gen 5, while AMD lists PCIe Gen 4 with 14 lanes on the CPU only. The process node difference is substantial: 7 nm for Intel versus 4 nm for AMD, which likely contributes to the AMD chip's single-core efficiency advantage. The socket types are incompatible: Intel uses BGA 2049, while AMD uses Socket FP8. Both are mobile parts with a 28 W TDP, and both are currently in active production.

The release dates are far apart. Intel launched in December 2023 with a launch MSRP of $375. AMD's release date is listed as January 2026, and no launch MSRP is recorded in the database. This makes the AMD part a much newer design, which helps explain its architectural advantages in certain workloads.

The Verdict

The data supports a clear split decision based on workload type. If the priority is single-threaded responsiveness, the AMD Ryzen AI 5 435 is the better choice. It wins every single-core benchmark by margins between 7.3% and 9.3%, and it also takes the extended instructions test by 15.1%. The newer 4 nm process and Zen 5 architecture clearly deliver per-core performance that Intel cannot match.

If the priority is multi-threaded throughput, the Intel Core Ultra 5 125H is the stronger option. It wins 10 of the 15 head-to-head tests, including all the major multi-core benchmarks. The 51.7% lead in find prime numbers and the 33.9% lead in physics are substantial, and the 14-core, 18-thread configuration provides a raw parallel advantage that AMD's 6 cores cannot overcome.

For mixed workloads, the average benchmark scores suggest a near tie: AMD at 28128 versus Intel at 27507, with both sitting in the 79th to 80th percentile range. The database places AMD's closest rivals as Intel parts (Core i5-13490F and Core i5-14500T), and Intel's closest rivals as AMD parts (Ryzen 7 5800 and Ryzen 7 5700X), which reinforces the overall parity.

The choice comes down to whether the workload favors single-core speed or multi-core capacity. AMD wins the former, Intel wins the latter. For a mobile user who runs office applications, web browsing, and light code compilation, the AMD chip's single-thread lead will feel snappier. For video rendering, 3D modeling, or any heavily threaded productivity task, Intel's extra cores will provide a measurable edge.

Where Each One Wins

Choose the Intel Core Ultra 5 125H if you need:

• Heavy multi-core rendering or encoding. The 19.9% lead in Cinebench R15 multi-core and 13% lead in R23 multi-core are the clearest signals.
• Math-heavy scientific workloads. The 27.2% advantage in floating-point math and 14.7% lead in integer math show a broad compute edge.
• Prime number or physics simulations. The 51.7% and 33.9% deltas, respectively, are the largest margins in the entire comparison.
• Data encryption tasks. Intel leads by 28.3%, which is substantial for security-related workloads.
• Higher data throughput. Intel wins data compression by 4.8% and random string sorting by 10.2%.

Choose the AMD Ryzen AI 5 435 if you need:

• The fastest single-threaded performance. The 7.3% to 9.3% leads across all single-core tests make it the better pick for legacy applications or lightly threaded software.
• Efficiency in extended instruction sets. The 15.1% win in PassMark extended instructions suggests better handling of SIMD-heavy code.
• Newer process technology. The 4 nm node from TSMC versus Intel's 7 nm is a significant architectural advantage.
• ECC memory support. This is a hard requirement for some workstation or server-adjacent uses, and only AMD offers it.
• A more recent design. The January 2026 release date versus December 2023 means the AMD platform is newer.

The overall average scores are close enough that either processor will handle general mobile computing duties without complaint. The database puts both in the top 20% of all CPUs, and their nearest rivals are comparable desktop parts from both brands. For a laptop buyer, the deciding factor should be the specific software mix: single-core-sensitive workflows point to AMD, while multi-core-heavy workflows point to Intel.
