The Verdict

The benchmark data splits this pairing into two distinct profiles. The AMD Ryzen AI 5 PRO 435 wins six of the eleven head-to-head tests and carries a much higher average score (37,762 versus 18,302). Its multithread advantage is substantial: 23.7% ahead in PassMark multithread, 88.5% ahead in integer math, and 58.5% ahead in data compression. Buyers who prioritize parallel throughput, data processing, and encryption should take the AMD part.

The Intel Core 3 305 wins five tests, and its victories cluster around single-thread responsiveness and specific math operations. It leads by 5.5% in single-thread score, 2.8% in floating-point math, and 50.4% in prime number generation. Its physics score is 19.3% higher. The Intel chip also uses less power (15 W TDP versus 28 W) and carries a launch MSRP of $309. However, its overall average score puts it at the 72nd percentile, 14 points below the AMD part's 86th percentile.

The database suggests two different buyers. The AMD Ryzen AI 5 PRO 435 suits workloads that spread across many threads and benefit from dual-channel memory bandwidth. The Intel Core 3 305 suits lighter, single-thread-focused tasks and scenarios where lower power draw matters more than raw multithread output.

Head-to-Head Benchmarks

The largest single win belongs to the AMD Ryzen AI 5 PRO 435 in PassMark integer math. It scores 60,879 against 32,295 for the Intel Core 3 305, a delta of 88.5%. This is a massive gap and reflects the AMD chip's 12 threads versus 6. Data compression shows a similar story: AMD scores 232,803 versus 146,857, a 58.5% advantage. Random string sorting also favors AMD by 41.5% (24,936 versus 17,623). Extended instructions go to AMD by 23.5% (16,724 versus 13,543). Multithread score goes to AMD by 23.7% (19,091 versus 15,439). Data encryption is close, with AMD ahead by 2.3% (11,267 versus 11,019).

The Intel Core 3 305's biggest win is in find prime numbers. It scores 115 versus 57, a 50.4% margin. This is the inverse of the multithread pattern: the Intel chip's single-thread efficiency shines in this workload. Physics goes to Intel by 19.3% (1,233 versus 995). Single-thread score goes to Intel by 5.5% (3,977 versus 3,757). Floating-point math goes to Intel by 2.8% (42,284 versus 41,114). The same single-thread result appears twice in the database under two test names, both showing 3,977 for Intel and 3,757 for AMD.

The pattern is clear. AMD wins where parallelism matters: integer math, compression, sorting, encryption, and overall multithread. Intel wins where single-thread speed and specific math operations dominate: prime numbers, physics, floating-point, and single-thread throughput. The delta magnitudes are asymmetric. AMD's wins range from 2.3% to 88.5%. Intel's wins range from 2.8% to 50.4%.

Specification Differences

The core counts are identical at 6, but threading differs sharply. The AMD Ryzen AI 5 PRO 435 supports 12 threads; the Intel Core 3 305 supports 6. Base clocks differ: AMD runs at 2.00 GHz, Intel at 1.50 GHz. Boost clocks are closer: AMD at 4.50 GHz, Intel at 4.30 GHz.

TDP differs by 13 watts. The AMD chip is rated at 28 W, the Intel chip at 15 W. Sockets differ: AMD uses Socket FP8, Intel uses BGA 1516. Process nodes differ: AMD on 4 nm TSMC, Intel on 3 nm Intel. Memory bus differs: AMD is dual-channel, Intel is single-channel. Memory bandwidth reflects that: AMD at 89.6 GB/s, Intel at 59.7 GB/s.

ECC memory support differs: AMD supports it, Intel does not. PCIe lanes differ: AMD provides Gen 4 with 14 lanes (CPU only), Intel provides Gen 4 with 6 lanes (CPU only). Integrated graphics differ: AMD uses Radeon 840M, Intel uses Xe3 Graphics (1 Xe). Cache structures differ in size and organization. The AMD chip lists L1 as 80 KB per core, L2 as 1 MB per core, and L3 as 4 MB. The Intel chip lists L1 as 192 KB, L2 as 2.5 MB, and L3 as 6 MB shared.

Release dates differ by about three months. The AMD part entered the database on 2026-01-04, the Intel part on 2026-04-15. The Intel chip has a launch MSRP of $309; the AMD chip has no recorded launch MSRP. Part numbers differ: AMD's is 100-000001788, Intel's is SAE3L.

Architecture Differences

The AMD Ryzen AI 5 PRO 435 uses Zen 5 architecture under the codename Gorgon Point. It belongs to the Ryzen AI PRO 400 generation, which the database notes as "Zen 5 / Zen 5c." This implies a hybrid core arrangement within the same family, though the specific core mix is not recorded. The process is 4 nm from TSMC.

The Intel Core 3 305 uses the Wildcat Lake codename. The database does not list a specific architecture name for it, but the generation is "Core 3 (Wildcat Lake)." The process is 3 nm from Intel's own foundry.

Cache layouts differ fundamentally. The AMD chip uses per-core L1 and L2 allocations: 80 KB L1 per core and 1 MB L2 per core, with a shared 4 MB L3. The Intel chip uses a single L1 figure of 192 KB, an L2 of 2.5 MB, and a shared 6 MB L3. The Intel L3 is 2 MB larger than the AMD L3, but the AMD per-core L2 allocation gives it 6 MB of total L2 across six cores versus 2.5 MB for Intel.

Threading architecture is the biggest differentiator. AMD's 12 threads come from 6 cores, meaning simultaneous multithreading is active. Intel's 6 threads from 6 cores means no SMT. This explains the large multithread deltas in the benchmark data.

Memory architecture differs. AMD uses dual-channel memory with 89.6 GB/s bandwidth; Intel uses single-channel with 59.7 GB/s. This 29.9 GB/s gap likely contributes to AMD's wins in memory-intensive tests like data compression and random string sorting.

PCIe capability differs: AMD provides 14 Gen 4 lanes versus Intel's 6. This affects expansion options for attached devices.

Integrated graphics differ in brand and configuration. AMD uses Radeon 840M, Intel uses Xe3 Graphics with 1 Xe core. The database does not record graphics benchmark scores, so no performance comparison is possible from this data.

Where Each One Wins

The AMD Ryzen AI 5 PRO 435 wins in workloads that scale with threads and memory bandwidth. Integer math shows the largest margin at 88.5%, indicating strong parallel integer throughput. Data compression follows at 58.5%, which also benefits from the dual-channel memory subsystem. Random string sorting at 41.5% and extended instructions at 23.5% reinforce the pattern. Multithread score at 23.7% confirms the overall parallel advantage. Data encryption is nearly even at 2.3%, but AMD still takes it.

The Intel Core 3 305 wins in single-thread-focused and math-specific workloads. Prime number generation is its standout at 50.4% over AMD, a result that likely reflects efficient single-core integer loops. Physics at 19.3% suggests better single-thread physics simulation performance. Single-thread score at 5.5% shows a modest but consistent lead in serial tasks. Floating-point math at 2.8% is close, but Intel edges it.

The use-case split follows the benchmark wins. AMD suits data-heavy, thread-hungry applications: compression, encryption, sorting, and multi-threaded productivity. Intel suits lighter workloads where one or two cores carry the load and where power consumption matters (15 W TDP versus 28 W). The Intel chip also offers a larger shared L3 cache (6 MB versus 4 MB), which may help in certain single-threaded access patterns.

The database does not record gaming or graphics scores, so the integrated GPU comparison remains qualitative. The AMD chip's dual-channel memory and higher TDP suggest more headroom for sustained loads, while Intel's lower TDP and smaller PCIe lane count point to a more constrained platform. Ultimately, the data shows two chips optimized for different ends of the mobile spectrum: AMD for throughput, Intel for efficiency and single-thread response.
