The architecture shift from Zen 3+ to Zen 4 brings a smaller process node, a larger L2 cache per core, higher clocks, lower TDP, ECC support, and a more capable integrated GPU. The 8640HS also carries the PRO branding, indicating a commercial-focused feature set. Both processors are locked, with no unlocked multiplier.

Where Each One Wins

The Ryzen 5 PRO 8640HS wins every benchmark category in the database. There is no recorded workload where the 7533HS takes a victory. The closest margin is in PassMark physics, where the 8640HS leads by 21.3%. The widest margin is in random string sorting, where the 8640HS leads by 41.6%. Single-thread performance shows a 23.1% advantage for the 8640HS in PassMark single-thread, while Cinebench R23 single-core shows a 31.8% lead. Multi-threaded workloads show a similar pattern: Cinebench R23 multi-core favors the 8640HS by 31.8%, and PassMark multithread favors it by 32.4%. Integer math shows a 27.3% lead, floating-point math a 35.4% lead, and extended instructions a 39.4% lead for the 8640HS. Data encryption shows a 28.4% advantage, data compression a 31.6% advantage, and prime number finding a 32.4% advantage.

Because the 7533HS has zero wins, the use-case split is straightforward. Any application that benefits from higher single-thread speed, higher multi-thread throughput, or specialized instruction throughput will favor the 8640HS. The only possible reason to consider the 7533HS would be if the lower power envelope were reversed, but the data shows the 8640HS actually has the lower TDP at 28 watts versus 35 watts. The 7533HS offers no measured benefit in any recorded category.

PassMark tests reveal a broader range of deltas. The smallest margin is in physics, where the 8640HS scores 1043 versus 821, a 21.3% lead. This suggests the physics workload is relatively less sensitive to the architectural improvements. The largest margin is in random string sorting, with 30235 versus 17669, a 41.6% lead. This workload likely benefits substantially from the larger L2 cache and higher clocks of the 8640HS. Extended instructions show a 39.4% lead (18507 versus 11219), and floating-point math shows a 35.4% lead (43019 versus 27800). Integer math shows a 27.3% lead (69839 versus 50800). Data compression shows a 31.6% lead (246446 versus 168692), while data encryption shows a 28.4% lead (14962 versus 10718). Prime number finding shows a 32.4% lead (71 versus 48). Multithread shows a 32.4% lead (21465 versus 14520). Single-thread shows a 23.1% lead (3561 versus 2740).

The average benchmark score for the 8640HS is 28478, while the 7533HS averages 19364. The 8640HS sits at the 80th percentile of all CPUs in the database, while the 7533HS sits at the 73rd percentile. The nearest rivals for the 8640HS include the Intel Xeon E-2436 at a 0.2% lower score, the AMD Ryzen 7 PRO 6850HS at 0.2% lower, and the Intel Core 5 220H at 0.3% lower. The nearest rivals for the 7533HS include the Intel Core Ultra 5 226V at a 0% delta, the Intel Core i5-1345U at 0.2% lower, and the Intel Core i7-8700K at 0.7% higher.
