AMD Ryzen 5 7533HS vs AMD Ryzen Embedded 8645HS Comparison

Head-to-Head Benchmarks

The database contains a full benchmark profile for the AMD Ryzen 5 7533HS, but the AMD Ryzen Embedded 8645HS has no recorded benchmark scores. The head-to-head comparison is therefore one-sided: all measured performance data comes from the 7533HS, while the 8645HS must be assessed on its architectural and specification differences alone. This asymmetry shapes the entire analysis.

The Ryzen 5 7533HS delivers a Cinebench R23 multi-core score of 12342 and a single-core score of 1742. In Cinebench R20, it records 5183 multi-core and 731 single-core. The R15 results show 1243 multi-core and 175 single-core. These scores place the 7533HS at the 73rd percentile among all CPUs in the database, with an average benchmark score of 19364. Its closest rival in the database is the Intel Core Ultra 5 226V at 19368, a delta of 0 percent, meaning the two are effectively tied in average score. The Intel Core i5-1345U sits at 19411, which is 0.2 percent higher than the 7533HS. The Intel Core i7-8700K trails by 0.7 percent at 19238, and the Intel Core i7-10700F leads by 0.7 percent at 19499.

PassMark results for the 7533HS show a multi-thread score of 14520, a single-thread score of 2740, and a physics score of 821. Integer math reaches 50800, floating point math reaches 27800, and extended instructions hit 11219. Data encryption scores 10718, data compression scores 168692, and random string sorting scores 17669. Prime number finding scores 48. These figures collectively give the 7533HS its positioning near the top of the 73rd percentile, within a narrow band of rivals that differ by less than one percent in either direction.

Since the 8645HS has no benchmark entries, there are no head-to-head wins to report for either processor. The recorded data cannot show which chip wins any specific workload test. What the data does show is the 7533HS's absolute performance profile and its standing relative to non-AMD rivals. The 8645HS's absence from the benchmark table means any claim about its speed must come from its higher clocks, newer architecture, and larger memory bandwidth, not from measured scores.

The Verdict

The data supports a straightforward division. The Ryzen 5 7533HS is the only one of the two with measured performance, and its numbers place it in the upper tier of the database. Its average benchmark score of 19364, its 73rd percentile ranking, and its near-tie with the Intel Core Ultra 5 226V all indicate a capable mobile processor for general multi-threaded and single-threaded workloads. The 8645HS, by contrast, has no benchmark data at all. It cannot be said to outperform the 7533HS in any measured test, because no test results exist for it.

However, the 8645HS's specifications point to a different positioning. It runs a Zen 4 architecture on a 4 nm process, compared to the 7533HS's Zen 3+ on a 6 nm process. Its base clock is 4.30 GHz against 3.30 GHz, and its boost clock is 5.00 GHz against 4.40 GHz. It has a 45 W TDP versus 35 W. These are not benchmark scores, but they are recorded facts that indicate a higher performance ceiling under sustained load, at the cost of more power. The 8645HS also supports ECC memory, which the 7533HS does not. That feature alone makes the 8645HS the data-backed choice for reliability-oriented embedded use cases.

The verdict from the recorded data: the 7533HS is the measured performer, the 8645HS is the specification-driven option. Neither can claim a benchmark victory over the other in this database, because head-to-head results are empty. The 7533HS wins on available evidence; the 8645HS wins on architectural headroom and features that the 7533HS simply does not offer.

Where Each One Wins

The 7533HS wins in every workload category that has a recorded score, simply because it is the only chip with scores. Its Cinebench R23 multi-core result of 12342 and single-core result of 1742 show balanced performance across both heavily threaded and lightly threaded tasks. PassMark integer math at 50800 and floating point math at 27800 indicate strong general computation. Data compression at 168692 and random string sorting at 17669 point to solid memory and cache handling. The 73rd percentile ranking confirms that this processor outperforms a majority of all CPUs in the database.

The 8645HS wins in specification comparisons where the 7533HS cannot match it. Its base clock of 4.30 GHz is exactly 1.00 GHz higher than the 7533HS's 3.30 GHz. Its boost clock of 5.00 GHz exceeds the 7533HS's 4.40 GHz by 0.60 GHz. Its memory bandwidth of 89.6 GB/s is higher than the 7533HS's 76.8 GB/s. Its L2 cache is 1 MB per core versus 512 KB per core. Its process node is 4 nm versus 6 nm. Its transistor count is 25,000 million, while the 7533HS has no recorded transistor count. Its integrated graphics is the Radeon 760M, a step above the 7533HS's Radeon 660M. Its 45 W TDP allows for higher sustained clocks than the 35 W TDP of the 7533HS, assuming adequate cooling.

The 8645HS also wins on ECC memory support, a feature the 7533HS lacks entirely. It uses AMD Socket FP8, while the 7533HS uses AMD Socket FP7. Its release date of 2024-04-01 precedes the 7533HS's release date of 2024-08-31 by five months. The 7533HS wins on having an established benchmark profile, while the 8645HS wins on every architectural specification where the two differ.
