AMD Ryzen 5 7533HS vs AMD Ryzen Embedded 8640U Comparison

AMD Ryzen 5 7533HS vs AMD Ryzen Embedded 8640U

The database places the AMD Ryzen 5 7533HS in the 73rd percentile of all CPUs, while the AMD Ryzen Embedded 8640U sits at the 50th percentile. The 7533HS carries an average benchmark score of 19364, whereas the 8640U has no recorded benchmark scores in the database, leaving its performance profile defined entirely by architectural specifications. The 7533HS faces nearest rivals including the Intel Core Ultra 5 226V with an average score of 19368 and a delta of 0 percent, the Intel Core i5-1345U at 19411 with a delta of -0.2 percent, the Intel Core i7-8700K at 19238 with a delta of 0.7 percent, and the Intel Core i7-10700F at 19499 with a delta of -0.7 percent. These deltas indicate the 7533HS performs within a narrow band near those desktop and mobile parts, sitting slightly behind the Core Ultra 5 226V by 4 points and ahead of the Core i7-8700K by 126 points in average score.

Where Each One Wins

The AMD Ryzen 5 7533HS wins decisively in every measurable benchmark category because it is the only one of the two with recorded data. Cinebench results show the 7533HS delivering a multicore score of 12342 in R23, a single-core score of 1742 in R23, a multicore score of 5183 in R20, a single-core score of 731 in R20, a multicore score of 1243 in R15, and a single-core score of 175 in R15. Passmark tests reinforce this dominance: the 7533HS posts 168692 in data compression, 10718 in data encryption, 11219 in extended instructions, 48 in find prime numbers, 27800 in floating point math, 50800 in integer math, 14520 in multithread, 821 in physics, 17669 in random string sorting, and 2740 in single thread. The 8640U has no benchmark entries, so head-to-head wins cannot be computed; the database records zero wins for each part.

The use-case split therefore rests on what each processor is designed to do rather than measured outcomes. The 7533HS, as a 7000 series mobile part, targets conventional laptop workloads where single-threaded responsiveness and sustained multicore throughput matter. Its Passmark single-thread score of 2740 and Cinebench R23 single-core score of 1742 indicate strong responsiveness for interactive applications. The 8640U, as an embedded 8000 series part, targets industrial and commercial systems where reliability features like ECC memory support take precedence over raw speed. The 7533HS wins for general-purpose mobile computing because it has actual performance data showing robust results across rendering, encryption, and math workloads. The 8640U wins for embedded deployments that require validated memory integrity, since it supports ECC while the 7533HS does not.

Architecture Differences

The two processors diverge at the architectural level. The 7533HS uses Zen 3+ architecture with the Rembrandt-R codename, built on a 6 nm process from TSMC, while the 8640U uses Zen 4 architecture with the Hawk Point codename, built on a 4 nm process from TSMC. The 4 nm node gives the 8640U a transistor count of 25,000 million and a die size of 178 mm², whereas the 7533HS has no transistor count recorded and a larger die size of 208 mm². The smaller process node and die size suggest the 8640U packs more density, though the 7533HS uses a larger physical area.

Core and cache structures differ in the L2 tier. Both parts have 6 cores and 12 threads, with 64 KB of L1 cache per core and 16 MB of shared L3 cache. The 7533HS provides 512 KB of L2 cache per core, while the 8640U doubles that to 1 MB per core. This larger per-core L2 cache on the 8640U can reduce latency for frequently accessed data, potentially benefiting workloads with tight loops. The L1 and L3 allocations remain identical between the two.

Clock speeds favor the 8640U. The 8640U has a base clock of 3.50 GHz and a boost clock of 4.90 GHz, compared to the 7533HS base of 3.30 GHz and boost of 4.40 GHz. The 8640U runs 0.20 GHz higher at base and 0.50 GHz higher at boost. Thermal design power moves in the opposite direction: the 7533HS has a TDP of 35 watts, while the 8640U has a TDP of 28 watts, meaning the higher-clocked part operates within a lower power envelope.

The integrated graphics differ as well. The 7533HS uses Radeon 660M, while the 8640U uses Radeon 760M. Memory bandwidth favors the 8640U at 89.6 GB/s versus 76.8 GB/s for the 7533HS, despite both supporting DDR5 over a dual-channel bus. The 8640U adds ECC memory support, a feature absent on the 7533HS. Both use PCIe Gen 4 with 20 lanes from the CPU only. Sockets differ: the 7533HS fits AMD Socket FP7, while the 8640U fits AMD Socket FP8. Release dates place the 8640U in April 2024 and the 7533HS in August 2024.

Head-to-Head Benchmarks

No head-to-head benchmark comparisons exist in the database for these two processors. The winsA and winsB fields both record zero, and the headToHeadBenchmarks array is empty. The only measurable performance data comes from the AMD Ryzen 5 7533HS, which has seventeen recorded benchmark scores. The AMD Ryzen Embedded 8640U has zero recorded benchmark scores, so direct numerical comparisons cannot be made.

The largest wins for the 7533HS, relative to its own dataset, appear in Passmark workloads. Data compression at 168692 points represents the highest absolute score among its recorded tests, followed by integer math at 50800 and floating point math at 27800. In Cinebench, the R23 multicore score of 12342 stands well above the R20 multicore score of 5183 and the R15 multicore score of 1243, showing scaling across render iterations. Single-core results remain consistent: R23 single-core at 1742, R20 single-core at 731, and R15 single-core at 175.

The 8640U offers no benchmark scores to compare, so its performance can only be inferred from specifications. Its higher boost clock of 4.90 GHz versus 4.40 GHz, larger L2 cache of 1 MB per core versus 512 KB, greater memory bandwidth of 89.6 GB/s versus 76.8 GB/s, and newer Zen 4 architecture on a 4 nm node versus Zen 3+ on 6 nm all point to potential advantages in latency-sensitive and bandwidth-bound tasks. The 7533HS counters with a higher TDP of 35 watts versus 28 watts, which can support sustained loads in a properly cooled chassis.

The percentile data reinforces the gap. The 7533HS ranks in the 73rd percentile of all CPUs, while the 8640U ranks in the 50th percentile. The 7533HS average benchmark score of 19364 places it near the Intel Core Ultra 5 226V at 19368, the Intel Core i5-1345U at 19411, the Intel Core i7-8700K at 19238, and the Intel Core i7-10700F at 19499. These nearby scores show the 7533HS performing at a level comparable to those established parts, with deltas ranging from -0.7 percent to 0.7 percent. The 8640U has no nearest rivals listed and no average score, so it cannot be positioned against those same references.

In practical terms, the 7533HS delivers measurable performance across rendering, encryption, compression, and math workloads, making it the only one of the two with verified results. The 8640U provides architectural improvements in clock speed, cache size, memory bandwidth, and process technology, plus ECC support, but the database contains no evidence of how those improvements translate into benchmark outcomes. Any comparison between the two must rely on the 7533HS scores as the sole performance reference, with the 8640U evaluated purely on its listed specifications.
