AMD Ryzen 5 7533HS vs Intel Core i7-1355U Comparison

The AMD Ryzen 5 7533HS and Intel Core i7-1355U are both mobile processors, but the recorded benchmark data shows two sharply different performance profiles. Across 17 head-to-head tests, the Intel part wins 9 and the AMD part wins 8, yet the margins reveal a deeper split. The Ryzen dominates sustained multi-core work with a 49% lead in Cinebench R23 multi-core, while the Core i7 counters with a 31.5% advantage in Cinebench R15 single-core and a 20.4% lead in Passmark single-thread. Both processors sit at the 73rd percentile of all CPUs in the database, with average benchmark scores of 19364 for the AMD and 18730 for the Intel.

Head-to-Head Benchmarks

The largest single margin in the entire comparison belongs to the AMD in Cinebench R23 multi-core. The Ryzen scores 12342 against the Intel's 8286, a 49% advantage that dwarfs every other result. This is the headline number: for rendering or any workload that scales across all cores, the AMD is in a different class. The same pattern appears in Passmark extended instructions, where the AMD leads by 28.6% (11219 vs 8726), and in data encryption, where it leads by 9% (10718 vs 9831). Data compression also favors the AMD by 8.3% (168692 vs 155727). In Cinebench R20, the AMD wins both multi-core and single-core by 4.7% (5183 vs 4949 and 731 vs 698). The Passmark multithread test goes to the AMD by a slim 1.5% (14520 vs 14299), and random string sorting by a razor-thin 0.2% (17669 vs 17631).

The Intel's counterattacks are concentrated in single-thread and floating-point territory. Its biggest win is Cinebench R15 single-core, where it scores 255.5 against the AMD's 175, a 31.5% lead. Passmark single-thread shows a 20.4% advantage (3444 vs 2740), and floating-point math favors the Intel by 20.5% (34965 vs 27800). Cinebench R15 multi-core goes to the Intel by 10.8% (1393 vs 1243), which is curious given that the AMD wins both R20 and R23 multi-core. Physics favors the Intel by 7.5% (888 vs 821), find prime numbers by 5.9% (51 vs 48), Cinebench R23 single-core by 4.5% (1825 vs 1742), and integer math by 2.3% (52002 vs 50800).

The pattern is consistent: the AMD wins the modern multi-core tests and the Intel wins the legacy single-thread tests. The R15 multi-core result is the outlier, standing apart from the R20 and R23 results where the AMD leads. The Intel's wins cluster in short-duration and lightly threaded workloads, while the AMD's wins concentrate in sustained all-core scenarios.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7533HS uses the Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC with a die size of 208 mm². The Intel Core i7-1355U uses the Raptor Lake architecture, codenamed Raptor Lake-U, built on a 10 nm process at Intel with no die size recorded.

The core configurations differ substantially. The AMD has 6 cores and 12 threads, all based on the same Zen 3+ design. The Intel has 10 cores and 12 threads, which implies a hybrid arrangement of performance and efficiency cores, a common approach in Raptor Lake parts. Both present 12 threads to the operating system, but the Intel needs more physical cores to reach that count.

Clock speeds tell a complementary story. The AMD has a base clock of 3.30 GHz and a boost clock of 4.40 GHz. The Intel has a much lower base clock of 1.70 GHz but a higher boost clock of 5.00 GHz. The lower base clock on the Intel is typical of a 15W part, while the AMD's 35W TDP allows a higher sustained baseline.

Cache hierarchies also differ. The AMD provides 64 KB of L1 and 512 KB of L2 per core, with 16 MB of shared L3. The Intel provides 80 KB of L1 and 1.25 MB of L2 per core, with 12 MB of shared L3. The Intel's larger per-core L2 cache likely contributes to its single-thread wins, while the AMD's larger L3 pool helps in multi-threaded scenarios.

Memory support is another differentiator. The AMD supports DDR5 only, with a recorded memory bandwidth of 76.8 GB/s over a dual-channel bus. The Intel supports both DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded. The AMD also offers more PCIe connectivity: Gen 4 with 20 lanes, versus Gen 4 with 8 lanes on the Intel.

Integrated graphics differ as well. The AMD pairs with a Radeon 660M, while the Intel uses Iris Xe Graphics 96EU. Both are mobile parts with locked multipliers, and both are currently in active production. The AMD was released on 2024-08-31, while the Intel came earlier on 2023-01-03.

The Verdict

The data points to a clear division of labor. The AMD Ryzen 5 7533HS is the stronger multi-core processor, with a 49% lead in Cinebench R23 multi-core and additional wins in data compression, data encryption, and extended instructions. The Intel Core i7-1355U is the stronger single-thread processor, with a 31.5% lead in Cinebench R15 single-core and a 20.4% lead in Passmark single-thread. The Intel wins more individual tests (9 vs 8), but the AMD's wins are larger in magnitude, and the AMD holds a higher average benchmark score (19364 vs 18730). Both sit at the 73rd percentile of all CPUs. The choice depends on workload: sustained multi-core work favors the AMD, while bursty single-thread tasks favor the Intel.

Where Each One Wins

The AMD Ryzen 5 7533HS wins in Cinebench R20 multi-core and single-core, Cinebench R23 multi-core, Passmark data compression, data encryption, extended instructions, multithread, and random string sorting. These are workloads that benefit from the 16 MB shared L3 cache, the higher 3.30 GHz base clock, and the 35W TDP that sustains performance over longer runs.

The Intel Core i7-1355U wins in Cinebench R15 multi-core and single-core, Cinebench R23 single-core, Passmark find prime numbers, floating-point math, integer math, physics, and single-thread. These are workloads that favor the 5.00 GHz boost clock and the larger 1.25 MB per-core L2 cache, which help in short, lightly threaded bursts.

For a laptop used primarily for rendering, compilation, or other all-core workloads, the AMD is the data-backed choice. For a laptop used for office tasks, web browsing, or applications that rely on single-thread speed, the Intel holds the advantage.
