AMD Ryzen 5 7545U vs AMD Ryzen 7 7435HS Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall victory for the AMD Ryzen 7 7435HS, which wins 13 of the 17 recorded head-to-head comparisons. However, the AMD Ryzen 5 7545U secures four wins, and those victories are concentrated in areas that reveal distinct performance characteristics.

Starting with the multi-core Cinebench tests, the Ryzen 7 7435HS leads consistently. In Cinebench R23 multi-core, the 7435HS scores 19,873 against 17,253 for the 7545U, a 13.2% advantage. The same 13.2% margin appears in Cinebench R20 multi-core (8,346 vs 7,246) and Cinebench R15 multi-core (2,003 vs 1,739). The single-core Cinebench results follow the same pattern, with the 7435HS ahead by 13.2% in R23 (2,805 vs 2,435), R20 (1,178 vs 1,022), and R15 (282 vs 245).

The PassMark suite reinforces this multi-core dominance. In integer math, the 7435HS posts 85,274 against 60,206, a 29.4% lead, the largest margin in any test. Floating point math shows a 24.8% advantage (48,863 vs 36,754). Data encryption favors the 7435HS by 23.8% (18,648 vs 14,202), and data compression by 23.1% (310,038 vs 238,345). Extended instructions see a 17.6% gap (21,690 vs 17,865). The PassMark multithread score gives the 7435HS a 13.2% edge (23,393 vs 20,298), and random string sorting is closer, at 4.6% (31,827 vs 30,358).

The Ryzen 5 7545U has its own bright spots. The most striking is PassMark single-thread, where it scores 3,673 against 3,167, a 16% advantage over the 7435HS. This is the largest single-core margin in either direction across the entire comparison. In find prime numbers, the 7545U wins 68 to 54, a 25.9% margin. It also takes PassMark physics, 1,057 to 991, a 6.7% lead. These wins, while fewer in number, show that the 7545U is not merely a weaker version of the 7435HS; it holds genuine advantages in specific workloads.

The average benchmark scores tell a similar story. The Ryzen 7 7435HS has an average benchmark score of 26,402, placing it in the 78th percentile of all CPUs. The Ryzen 5 7545U averages 26,849, in the 79th percentile. Despite losing most head-to-head tests, the 7545U has a slightly higher average score and percentile ranking. The nearest rivals for each processor are informative: the 7545U sits within 0.4% of the AMD Ryzen 5 5500GT and AMD EPYC 9554, and within 0.3% of the AMD Ryzen AI 7 445, while the 7435HS is within 0.3% of the AMD Ryzen 5 7600 and within 0.2% of the AMD Ryzen 5 8640U. The 7435HS also sits within 0.3% of the Intel Core i9-12900HK and Intel Core i7-1280P.

Architecture Differences

The two processors come from different architectural generations, which explains much of the performance split. The Ryzen 5 7545U uses the Zen 4 architecture, specifically the Phoenix2 codename, built on a 4 nm process at TSMC. The Ryzen 7 7435HS uses the older Zen 3+ architecture, codenamed Rembrandt-R, on a 6 nm process, also at TSMC. The die size reflects this: the 7545U measures 137 mm² with 20,900 million transistors, while the 7435HS is larger at 210 mm², though its transistor count is not recorded.

Core and thread counts differ. The 7545U has 6 cores and 12 threads, while the 7435HS has 8 cores and 16 threads. This two-core, four-thread advantage is the primary reason for the 7435HS's multi-core wins. Cache configurations also differ. Both have 64 KB of L1 cache per core and 16 MB of shared L3 cache, but the L2 cache is not equal: the 7545U has 1 MB per core, while the 7435HS has 512 KB per core. The 7545U therefore has a total of 6 MB of L2 cache, while the 7435HS has 4 MB, giving the smaller processor a per-core cache advantage.

Clock speeds are close but favor the 7545U. It has a base clock of 3.20 GHz and a boost clock of 4.90 GHz. The 7435HS has a base clock of 3.10 GHz and a boost clock of 4.50 GHz. The 7545U's higher boost clock, combined with its newer Zen 4 architecture, explains its single-thread and physics wins.

Power and thermals are a significant differentiator. The 7545U has a TDP of 28 watts, while the 7435HS is rated at 45 watts. Both use the AMD Socket FP7. Memory support is DDR5 for both, with dual-channel buses, but the 7545U has a higher memory bandwidth at 89.6 GB/s versus 76.8 GB/s for the 7435HS. Both support ECC memory.

PCIe connectivity also differs. The 7545U provides Gen 4 with 14 lanes (CPU only), while the 7435HS provides Gen 4 with 20 lanes (CPU only). The integrated graphics situation is a major difference: the 7545U includes Radeon 740M integrated graphics, while the 7435HS has no integrated graphics listed. Neither processor has an unlocked multiplier. The 7545U carries part numbers 100-000000930 (FP7r2) and 100-000000929 (FP7), while the 7435HS uses 100-000001506. The 7545U has a recorded release date of November 1, 2023, while the 7435HS has no release date in the database.

Where Each One Wins

The Ryzen 7 7435HS is the clear choice for multi-threaded workloads. Its 8 cores and 16 threads give it substantial advantages in integer math, floating point math, data compression, and data encryption. The 29.4% lead in integer math and 24.8% lead in floating point math are the largest margins in the entire comparison. For content creation tasks like video rendering, 3D modeling, and software compilation, the 7435HS is the stronger processor. Its Cinebench multi-core results, with a 13.2% edge across R15, R20, and R23, confirm consistent scaling in render-style workloads.

The Ryzen 5 7545U wins in scenarios that reward high single-thread performance and low-latency response. Its 16% PassMark single-thread advantage over the 7435HS is decisive. Applications that depend heavily on one or two threads, such as many games, legacy software, and certain simulation workloads, will favor the 7545U. The find prime numbers result, where the 7545U wins by 25.9%, suggests an advantage in integer-heavy single-threaded calculations. The physics test, won by 6.7%, reinforces this pattern. The 7545U also benefits from its higher memory bandwidth (89.6 GB/s vs 76.8 GB/s) and its lower TDP of 28 watts, which makes it better suited for thinner, lighter laptops where thermal headroom is limited.

The 7435HS has no integrated graphics, so systems using it require a discrete GPU. The 7545U includes Radeon 740M integrated graphics, which allows for basic display output and light graphics tasks without a separate graphics card. For users who need a laptop with a dedicated GPU anyway, the 7435HS's lack of integrated graphics is not a drawback. For users who want a more versatile processor that can handle display duties on its own, the 7545U has a clear advantage.

The Verdict

The data supports a straightforward recommendation for most users: the Ryzen 7 7435HS is the stronger processor for multi-threaded workloads. It wins 13 of 17 head-to-head tests, with particularly large margins in integer math (29.4%), floating point math (24.8%), and data encryption (23.8%). Its 8 cores and 16 threads, higher TDP of 45 watts, and larger 210 mm² die give it the raw compute capacity that the 7545U cannot match. Users who render video, compile code, or run heavily threaded simulations should choose the 7435HS.

The Ryzen 5 7545U is the better choice for specific use cases. Its 16% PassMark single-thread advantage and 25.9% win in find prime numbers indicate that lightly threaded applications run faster on this chip. Its 28-watt TDP makes it more suitable for thin-and-light laptops with limited cooling. Its integrated Radeon 740M graphics means it can operate without a discrete GPU, and its higher memory bandwidth of 89.6 GB/s adds another point in its favor. The slightly higher average benchmark score (26,849 vs 26,402) and percentile ranking (79th vs 78th) suggest that, in mixed workloads, the 7545U is not far behind despite losing most individual tests.

The choice comes down to workload. For maximum multi-thread performance, pick the Ryzen 7 7435HS. For single-thread responsiveness, lower power consumption, and integrated graphics, the Ryzen 5 7545U is the data-backed selection.
