AMD Ryzen 5 7533HS vs Intel Core i5-1335U Comparison

The Intel Core i5-1335U and AMD Ryzen 5 7533HS are both mobile processors aimed at thin-and-light laptops, but the benchmark data reveals two very different performance profiles. The Intel chip wins 9 of the 17 head-to-head tests, while the AMD chip wins 8, yet the margins in those wins are drastically uneven, creating a clear split between single-threaded agility and sustained multi-core throughput.

Head-to-Head Benchmarks

The most lopsided result in the entire comparison is in Cinebench R15 single-core, where the Intel Core i5-1335U scores 238 against the AMD Ryzen 5 7533HS’s 175, a 36% advantage. This is the largest deltaPct in either direction across all tests. The Intel part also dominates PassMark single-thread performance, scoring 3336 versus 2740, a 21.8% lead. These two results indicate that for lightly-threaded tasks, the Intel processor has a decisive edge in raw per-core responsiveness.

The Intel chip’s lead extends to floating-point math, where it scores 35176 versus 27800, a 26.5% advantage. This is a substantial gap in a workload that often benefits from wider execution resources or better vector throughput. Smaller but still notable Intel wins appear in integer math (51244 vs 50800, a 0.9% edge), PassMark physics (837 vs 821, +1.9%), and random string sorting (17953 vs 17669, +1.6%). The two processors tie exactly in PassMark find prime numbers, both scoring 48.

The AMD Ryzen 5 7533HS takes its biggest win in Cinebench R23 multi-core, scoring 12342 against the Intel’s 8889.5, a 28% margin. This is the single largest score difference in absolute terms and shows that under sustained multi-threaded load, the AMD chip pulls far ahead. The trend continues in Cinebench R20 multi-core, where AMD wins 5183 to 4935, a 4.8% edge. However, the Intel chip wins Cinebench R15 multi-core 1464 to 1243, a 17.8% margin, which suggests that the shorter the multi-core burst, the better the Intel part performs relative to its sustained output.

AMD also wins in extended instructions, scoring 11219 versus 8974, a 20% advantage, which is a strong indicator for workloads that leverage AVX or similar instruction sets. In data compression, AMD leads 168692 to 159593, a 5.4% margin, and in data encryption, AMD leads 10718 to 10009, a 6.6% edge. The PassMark multithread score narrowly favors AMD at 14520 versus 14281, a 1.6% difference. In Cinebench R23 single-core, AMD wins 1742 to 1684.5, a 3.3% margin, and in Cinebench R20 single-core, AMD wins 731 to 696, a 4.8% margin.

The pattern is clear: Intel wins the short, bursty single-thread tests and some math workloads, while AMD wins the longer, sustained multi-thread tests and several memory-bandwidth-sensitive tasks. The overall average benchmark scores reflect this, with the Intel chip at 18982 and the AMD chip at 19364, a 2% difference favoring AMD.

Architecture Differences

The two processors come from different design philosophies and process nodes. The Intel Core i5-1335U is built on Intel’s 10 nm process and uses the Raptor Lake architecture, specifically the Raptor Lake-U codename. It features a hybrid core layout with 10 cores and 12 threads, which implies a mix of performance and efficiency cores. The AMD Ryzen 5 7533HS uses TSMC’s 6 nm process with the Zen 3+ architecture, codenamed Rembrandt-R, and has 6 cores and 12 threads, a more traditional homogeneous design.

Cache structures differ significantly. The Intel chip has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The larger L3 on the AMD side likely contributes to its multi-threaded performance, while the larger per-core L1 and L2 on the Intel side may help with single-thread latency.

Memory support also diverges. The Intel chip supports both DDR4 and DDR5 memory in a dual-channel configuration, while the AMD chip supports only DDR5 but with a specified memory bandwidth of 76.8 GB/s. The AMD chip also has more PCIe lanes, offering Gen 4 with 20 lanes (CPU only), compared to Intel’s Gen 4 with 8 lanes (CPU only). This gives the AMD platform more headroom for external devices.

The integrated graphics differ: Intel uses Iris Xe Graphics 80EU, while AMD uses Radeon 660M. Process node and foundry also differ, with Intel using its own foundry on 10 nm and AMD using TSMC on 6 nm. The AMD chip has a known die size of 208 mm², while the Intel chip’s die size is not listed. The Intel processor has a launch MSRP of $340; no MSRP is listed for the AMD part. The AMD chip has a higher TDP of 35 watts versus Intel’s 15 watts, which explains its ability to sustain higher multi-core clocks.

Where Each One Wins

The Intel Core i5-1335U wins in scenarios that favor rapid, short-duration responses. Its 36% lead in Cinebench R15 single-core and 21.8% lead in PassMark single-thread make it the stronger choice for everyday responsiveness, such as launching applications, quick file operations, or any task that is latency-bound. Its 26.5% advantage in floating-point math also makes it suitable for spreadsheet calculations, light media encoding, or other number-crunching tasks that are not heavily multi-threaded. The wins in integer math, physics, and random string sorting reinforce this profile of a chip that excels at bursty, single-threaded workloads.

The AMD Ryzen 5 7533HS wins in sustained, heavy multi-threaded workloads. Its 28% lead in Cinebench R23 multi-core is the defining result, making it the better choice for video editing, 3D rendering, software compilation, or any task that can fully utilize all cores for extended periods. The 20% advantage in extended instructions and the wins in data compression and encryption suggest it is also better for server-like tasks, archiving, and secure data processing. The 1.6% win in PassMark multithread, while narrow, confirms that AMD holds the edge when all threads are active simultaneously.

The Verdict

The choice between these two processors depends entirely on the workload profile. The data shows that the Intel Core i5-1335U is the better performer for single-threaded tasks and short bursts of activity, offering a 36% lead in Cinebench R15 single-core and a 26.5% lead in floating-point math. It is the right pick for users who prioritize snappy system feel, office productivity, and applications that do not scale well across many cores.

The AMD Ryzen 5 7533HS is the clear winner for sustained multi-threaded performance, with a 28% lead in Cinebench R23 multi-core and a 20% advantage in extended instructions. Its higher TDP of 35 watts and larger 16 MB L3 cache give it the headroom to maintain performance under load. For users who regularly render, encode, or compile, the AMD chip is the better choice, despite its lower single-thread scores in the older Cinebench R15 test. The AMD part also edges out Intel in overall average benchmark score, 19364 to 18982, reinforcing that it is the more powerful processor for demanding, multi-threaded applications.
