AMD Ryzen 5 7535HS vs Intel Core i7-1355U Comparison

The AMD Ryzen 5 7535HS and Intel Core i7-1355U are both mobile processors released on the same date, targeting thin-and-light laptops, but they take fundamentally different approaches. The data shows a clear split: the AMD chip dominates multi-threaded workloads while the Intel part claims single-threaded superiority. This analysis breaks down the benchmark results, architectural choices, and practical implications for each processor.

Head-to-Head Benchmarks

The head-to-head comparison consists of 15 benchmark results, with the AMD Ryzen 5 7535HS winning 9 of them and the Intel Core i7-1355U taking 6. The most decisive AMD victory comes in PassMark extended instructions, where the Ryzen scores 15411 versus Intel’s 8726, a 76.6% advantage. This is the largest delta in the entire comparison and suggests the AMD architecture handles complex instruction sets far more efficiently.

Data compression is another major AMD win, with the Ryzen posting 221668 compared to Intel’s 155727, a 42.3% margin. Similarly, data encryption shows a 38.9% lead (13656 vs 9831), and random string sorting favors AMD by 29.2% (22781 vs 17631). These results indicate the Ryzen 5 7535HS is substantially faster at memory-intensive and algorithmic tasks.

The multi-threaded PassMark score reinforces this trend, with AMD at 17914 versus Intel’s 14299, a 25.3% gap. Integer math also favors the Ryzen significantly, 62372 versus 52002, a 19.9% difference. In Cinebench R23 multi-core, the AMD chip scores 8613 against Intel’s 8286, a more modest 3.9% lead, while Cinebench R15 multi-core shows a 4.6% advantage (1457 vs 1393). Floating-point math is nearly a tie, with AMD ahead just 1.6% (35540 vs 34965).

The Intel Core i7-1355U, however, dominates single-threaded tests. The biggest gap is in Cinebench R23 single-core, where Intel scores 1825 against AMD’s 1445, a 20.8% advantage. Cinebench R15 single-core shows Intel leading by 9.2% (255.5 vs 232), and PassMark single-thread results confirm the pattern, with Intel at 3444 versus AMD’s 3123, a 9.3% gap. The Intel chip also wins PassMark physics (888 vs 844, a 5% lead) and find prime numbers (51 vs 49, a 3.9% margin).

Overall average benchmark scores place the Ryzen 5 7535HS at 19047 and the Intel Core i7-1355U at 18730. Both processors sit at the 73rd percentile among all CPUs. The nearest rivals for the AMD chip include the Intel Core i5-12400F (avg score 19039, 0% delta) and the Intel Core 3 201E (19056, 0% delta). For the Intel part, the closest competitors are the AMD EPYC 7643 (18697, 0.2% delta) and the Intel Core i5-12400 (18683, 0.3% delta). These figures show both chips performing in the same broad tier, yet with very different workload profiles.

Architecture Differences

The Ryzen 5 7535HS uses AMD’s Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC. It features 6 cores and 12 threads, which is the same thread count as the Intel chip but with fewer physical cores. The base clock is 3.30 GHz with a boost clock of 4.55 GHz, and it runs at a 35 W TDP. The die size is 208 mm², and it uses the AMD Socket FP7.

The Intel Core i7-1355U employs Raptor Lake architecture, specifically Raptor Lake-U, manufactured on Intel’s 10 nm process. It has 10 cores and 12 threads, meaning it relies on a hybrid core arrangement to reach that thread count. The base clock is listed at 1700.00 MHz with a boost clock of 5.00 GHz, and the TDP is much lower at 15 W. The socket is Intel BGA 1744.

Cache configurations differ notably. The AMD chip provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The Intel part offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. While Intel has more L1 and L2 per core, AMD’s larger L3 pool may benefit multi-threaded workloads.

Memory support diverges as well. The Ryzen 5 7535HS supports only DDR5 memory with dual-channel configuration and a memory bandwidth of 76.8 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, but no memory bandwidth figure is listed. This gives the Intel part more flexibility for system builders, though the AMD chip has a specified bandwidth advantage.

PCIe connectivity is another differentiator. The AMD processor offers PCIe Gen 4 with 20 lanes (CPU only), while the Intel chip provides PCIe Gen 4 with only 8 lanes (CPU only). This means the Ryzen can support more Gen 4 devices directly, which could matter for storage or discrete GPU configurations.

Integrated graphics also differ. The AMD chip includes Radeon 660M graphics, while the Intel part features Iris Xe Graphics 96EU. Neither chip has ECC memory support, and both are unlocked for overclocking, though the multiplier is locked on both. The Intel part has a launch MSRP of $469, while the AMD chip has no listed launch MSRP.

The Verdict

The benchmark data paints a clear picture for different user priorities. The AMD Ryzen 5 7535HS is the stronger choice for multi-threaded productivity, offering substantial leads in data compression (42.3%), encryption (38.9%), and extended instructions (76.6%). It also wins the overall PassMark multithread score by 25.3%. For users running parallel workloads, video encoding, or heavy spreadsheet calculations, the Ryzen’s 9 out of 15 benchmark wins should translate to real-world responsiveness.

The Intel Core i7-1355U, despite having only 6 wins, holds a decisive edge in single-threaded performance. Its 20.8% lead in Cinebench R23 single-core and 9.3% lead in PassMark single-thread suggest it will feel snappier in everyday tasks like web browsing, document editing, and other lightly threaded applications. The higher boost clock of 5.00 GHz versus 4.55 GHz likely contributes to this advantage.

The TDP difference is notable: the Intel chip runs at 15 W versus AMD’s 35 W. This suggests the Intel part may be more suitable for fanless or ultra-thin designs, while the AMD chip’s higher power envelope could allow for more sustained performance in heavier workloads. The higher PCIe lane count on the AMD side (20 vs 8) also makes it more attractive for systems needing multiple Gen 4 devices.

Neither processor has a clear overall winner, as both sit at the 73rd percentile. The average benchmark scores are close (19047 vs 18730), but the distribution of wins reveals distinct strengths. The verdict is workload-dependent: choose the AMD Ryzen 5 7535HS for multi-core heavy tasks and the Intel Core i7-1355U for single-thread responsiveness.

Where Each One Wins

The AMD Ryzen 5 7535HS is the clear choice for multi-threaded workloads. Its wins in data compression (42.3% ahead), data encryption (38.9%), extended instructions (76.6%), and integer math (19.9%) make it suited for tasks like file archiving, database operations, cryptographic processing, and scientific computing. The 25.3% lead in PassMark multithread also suggests better performance in video rendering, software compilation, and other parallel tasks. The higher PCIe lane count (20 vs 8) means it can handle more Gen 4 devices, which is useful for systems with multiple NVMe drives or external GPU enclosures.

The Intel Core i7-1355U wins in single-threaded and latency-sensitive scenarios. Its 20.8% lead in Cinebench R23 single-core and 9.3% lead in PassMark single-thread make it better for web browsing, office productivity, and application startup times. Wins in physics (5% lead) and find prime numbers (3.9% lead) suggest it handles lighter math workloads efficiently. The lower 15 W TDP could also make it more attractive for ultra-portable laptops where battery life and thermal management are priorities, though this is not directly measured in the benchmark data.

Both processors are active production parts released on the same date, so neither has an availability advantage. The Intel chip has a launch MSRP of $469, while the AMD chip has no listed price. The choice ultimately depends on whether the user prioritizes multi-core throughput (AMD) or single-core responsiveness (Intel), with the benchmark data showing distinct strengths for each.
