AMD Ryzen 7 7435HS vs AMD Ryzen AI 5 340 Comparison

The AMD Ryzen AI 5 340 and AMD Ryzen 7 7435HS present a classic trade-off between architectural efficiency and raw core count. The data shows a clear split: the Ryzen 7 7435HS dominates in absolute multi-threaded workloads, winning 11 of 15 head-to-head benchmarks, while the Ryzen AI 5 340 secures a decisive victory in single-threaded performance and specific physics-based tests. The Ryzen AI 5 340's 16.3% lead in Passmark single-thread (3683 vs 3167) and its 33.3% advantage in prime number finding (72 vs 54) highlight the newer Zen 5 architecture's strengths, yet the 7435HS's additional two cores and 16 MB of L3 cache prove overwhelming in most productivity scenarios.

The Verdict

The benchmark results indicate that the AMD Ryzen 7 7435HS is the superior choice for users prioritizing multi-threaded throughput, as it leads by 36.9% in Cinebench R23 multi-core (19873 vs 12532) and by 38.5% in Passmark data encryption (18648 vs 11470). This processor also wins in Cinebench R15 single-core by 14% (282 vs 242.6), which is surprising given the Ryzen AI 5 340's higher boost clock of 4.80 GHz versus 4.50 GHz.

The AMD Ryzen AI 5 340 should be selected by users who value single-thread responsiveness and specific integer workloads, as it wins Passmark single-thread by 16.3% (3683 vs 3167) and Passmark physics by 10.5% (1095 vs 991). However, the data shows that the 7435HS's 8-core/16-thread configuration provides a 58.6% advantage in Cinebench R23 multi-core scoring, making it the clear pick for rendering, compilation, or any workload that scales with core count.

Both processors sit at the 78th percentile of all CPUs, but their average benchmark scores differ by only 421 points (26402 vs 25981), suggesting the 7435HS has a slight overall edge despite its older Zen 3+ architecture. The verdict is straightforward: choose the Ryzen AI 5 340 for its superior single-core efficiency and lower power envelope, or the Ryzen 7 7435HS for uncompromising multi-threaded performance.

Architecture Differences

The architectural divide between these two mobile processors is substantial. The AMD Ryzen AI 5 340 uses the Zen 5 architecture on a 4 nm TSMC process, with a die size of 195 mm², while the AMD Ryzen 7 7435HS employs the older Zen 3+ architecture on a 6 nm process with a 210 mm² die. This process advantage explains why the AI 5 340 can achieve higher boost clocks (4.80 GHz vs 4.50 GHz) while maintaining a significantly lower TDP of 28 watts versus 45 watts for the 7435HS.

Cache configurations differ markedly: the AI 5 340 offers 80 KB L1 and 1 MB L2 per core, plus 8 MB of L3 cache, whereas the 7435HS provides 64 KB L1 and 512 KB L2 per core, but doubles the L3 to 16 MB shared. The 7435HS's larger L3 cache likely contributes to its strong multi-threaded showing, despite the AI 5 340's architectural advantages.

The AI 5 340 includes integrated graphics (Radeon 840M), while the 7435HS has no integrated graphics listed, requiring a discrete GPU. Memory support also differs: the AI 5 340 supports both DDR5 and LPDDR5X with 89.6 GB/s bandwidth, while the 7435HS supports only DDR5 at 76.8 GB/s. The 7435HS offers ECC memory support, which the AI 5 340 lacks, and provides 20 PCIe Gen 4 lanes versus 16 for the AI 5 340.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 7 7435HS comes in Cinebench R23 multi-core, where it scores 19873 against the AI 5 340's 12532, a 36.9% margin. This pattern repeats across most multi-threaded tests: data compression shows a 25.9% lead (310038 vs 229796), integer math shows a 26% lead (85274 vs 63078), and floating-point math shows an 18.2% lead (48863 vs 39967). The 7435HS also wins Cinebench R15 multi-core by 4.4% (2003 vs 1915) and R15 single-core by 14% (282 vs 242.6).

The AMD Ryzen AI 5 340's victories are concentrated in specific areas. Its Passmark single-thread score of 3683 beats the 7435HS's 3167 by 16.3%, and it wins Passmark physics by 10.5% (1095 vs 991). The most striking win is in Passmark find prime numbers, where the AI 5 340 scores 72 versus 54, a 33.3% advantage that suggests superior integer processing efficiency per clock.

The 7435HS also wins in extended instructions by 24.2% (21690 vs 16440), random string sorting by 21.5% (31827 vs 24970), and Passmark multithread by 16.6% (23393 vs 19506). The data reveals that while the AI 5 340's Zen 5 cores are more efficient per thread, the 7435HS's two additional cores (8 vs 6) and 16 threads versus 12 provide an insurmountable advantage in heavily parallel tasks.

It dominates in Cinebench R23 multi-core by 36.9%, making it suitable for video rendering, 3D modeling, and software compilation. Its 25.9% lead in data compression (310038 vs 229796) and 26% lead in integer math (85274 vs 63078) indicate strong performance in database operations, encryption, and scientific computing. The 7435HS also wins in extended instructions by 24.2%, suggesting better AVX-512 or similar workload handling.

The AMD Ryzen AI 5 340 wins in scenarios requiring fast single-thread response and specific physics calculations. Its 16.3% Passmark single-thread lead (3683 vs 3167) makes it preferable for everyday applications like web browsing, office work, and lightweight coding where single-core speed matters most. The 10.5% physics win (1095 vs 991) and 33.3% prime number advantage (72 vs 54) suggest it handles certain gaming physics and cryptographic operations more efficiently.

For mobile users, the AI 5 340's 28 watt TDP versus 45 watts for the 7435HS is a crucial differentiator, enabling thinner, cooler laptops with longer battery life.
