AMD Ryzen 5 7533HS vs AMD Ryzen 9 8945HX Comparison

Where Each One Wins

The benchmark data is unambiguous in its overall shape: the AMD Ryzen 9 8945HX wins every single recorded comparison in this database matchup. Across all 17 head-to-head tests, the Ryzen 9 takes the victory, while the Ryzen 5 7533HS records zero wins. That does not make the 7533HS a poor processor; it makes it a different class of part. The 8945HX sits in the 95th percentile of all CPUs tracked, while the 7533HS lands in the 73rd percentile. That gap of 22 percentile points explains why the Ryzen 9 wins everywhere, but the nature of each workload still matters for practical use.

The Ryzen 5 7533HS is a 35-watt, 6-core mobile chip designed for efficiency-oriented laptops. Its strength is not raw throughput; its strength is fitting into thinner chassis with modest cooling. The data shows its single-thread PassMark score of 2740, which is respectable for a low-power part. In light workloads, such as everyday productivity and web browsing, the 7533HS will feel responsive. Its PassMark single-thread result trails the 8945HX by 29.9%, which is a meaningful but not catastrophic deficit for single-core tasks.

The Ryzen 9 8945HX is a 55-watt, 16-core flagship mobile processor. It dominates in every multi-threaded metric. Cinebench R23 multi-core shows a score of 42713 versus 12342 for the 7533HS, a 71.1% lead. PassMark multi-thread shows 51405 versus 14520, a 71.8% lead. The largest single delta appears in PassMark find prime numbers, where the 8945HX scores 262 versus 48, a 81.7% advantage. That test is heavily dependent on integer throughput and core count, so the 16-core part naturally crushes the 6-core part.

For workloads like video rendering, code compilation, 3D modeling, and scientific simulation, the 8945HX is the clear choice. The data compression test shows 677755 versus 168692, a 75.1% lead. Floating point math shows 117453 versus 27800, a 76.3% lead. These are exactly the kinds of tasks that benefit from more cores, higher clocks, and newer architecture. The 7533HS cannot compete in these areas, nor is it meant to.

Architecture Differences

The two processors come from different AMD generations and use different silicon. The Ryzen 5 7533HS belongs to the 7000 series, uses the Zen 3+ architecture, and carries the Rembrandt-R codename. The Ryzen 9 8945HX belongs to the 8000 series, uses Zen 4, and carries the Dragon Range codename. Zen 3+ is an optimized version of Zen 3, while Zen 4 is a full architectural refresh. The process node differs as well: the 7533HS is built on TSMC 6 nm, while the 8945HX is built on TSMC 5 nm. The 5 nm process allows higher transistor density and better power efficiency at high clocks.

The core counts diverge sharply. The 7533HS has 6 cores and 12 threads, while the 8945HX has 16 cores and 32 threads. That is a 10-core, 20-thread gap. The 8945HX also has a higher boost clock at 5.40 GHz versus 4.40 GHz, and a lower base clock at 2.50 GHz versus 3.30 GHz. The lower base clock is typical for a high-core-count part that needs to manage thermals at idle or low load.

Cache configurations also differ. Both have 64 KB of L1 per core. The L2 cache is 512 KB per core on the 7533HS and 1 MB per core on the 8945HX. The L3 cache is 16 MB shared on the 7533HS versus 64 MB on the 8945HX. That 48 MB difference is substantial for workloads that fit in cache, such as database queries or certain physics simulations. The 8945HX uses a dual-die design with two 71 mm² chiplets, while the 7533HS uses a single 208 mm² die. The 8945HX has 13,140 million transistors across its two dies.

Memory support is DDR5 for both, with dual-channel buses. The 8945HX has higher memory bandwidth at 83.2 GB/s versus 76.8 GB/s for the 7533HS. PCIe support also differs: the 7533HS offers Gen 4 with 20 CPU lanes, while the 8945HX offers Gen 5 with 28 CPU lanes. That matters for fast NVMe storage and external GPU enclosures. The integrated graphics differ as well: the 7533HS uses a Radeon 660M, while the 8945HX uses a Radeon 610M. The 660M is the more capable iGPU for light gaming or media work, based on its positioning, though no direct benchmark comparison is in the data. The 8945HX has an unlocked multiplier, while the 7533HS does not. The sockets are different too: AMD Socket FP7 for the 7533HS, AMD Socket FL1 for the 8945HX.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern. In Cinebench R15 multi-core, the 8945HX scores 4305 against 1243, a 71.1% lead. Single-core R15 shows 607 versus 175, also a 71.2% lead. R20 multi-core repeats the 71.1% delta with 17939 versus 5183. R20 single-core again shows 71.1% with 2532 versus 731. R23 multi-core shows the same 71.1% with 42713 versus 12342. R23 single-core shows 6030 versus 1742, also 71.1%. The consistency of the delta across Cinebench versions indicates that the performance gap scales linearly with core count and clock speed, not with workload-specific optimizations.

PassMark tests tell a more varied story. The single-thread test shows the smallest gap at 29.9%, with 3907 versus 2740. That is the closest result in the entire dataset. It suggests that for lightly threaded tasks, the Zen 4 architecture and higher boost clock give the 8945HX a real but limited edge. The physics test shows a 62.1% gap, with 2168 versus 821. That is the second-smallest delta. Physics simulations often scale with core count, but they also depend on single-thread efficiency, which narrows the gap somewhat.

The largest deltas come from integer-heavy and instruction-heavy workloads. PassMark find prime numbers shows a 81.7% gap. Extended instructions shows a 77.5% gap with 49823 versus 11219. Random string sorting shows a 77.6% gap with 78781 versus 17669. These tests favor the 16-core part because they are parallelizable and benefit from the larger L3 cache. Data encryption shows a 73.8% gap, data compression 75.1%, floating point math 76.3%, and integer math 74%. The multi-thread test shows a 71.8% gap.

The average benchmark score tells the overall story: 76212 for the 8945HX versus 19364 for the 7533HS. That is roughly a 4x difference in aggregate throughput. The nearest rivals for the 8945HX include the Intel Core Ultra 9 285HX at 76155 (0.1% delta), the AMD EPYC Embedded 8224P at 76492 (-0.4%), and the AMD Ryzen 9 9950X3D at 75779 (0.6%). The 7533HS sits near the Intel Core Ultra 5 226V at 19368 (0% delta) and the Intel Core i7-8700K at 19238 (0.7% delta). These comparisons show that the 7533HS is competitive with older desktop i7 parts, while the 8945HX trades blows with current flagship HX-class silicon.

The Verdict

The data supports a clear split. The Ryzen 9 8945HX is the superior processor for any workload that can use more than 6 cores. It wins every benchmark in the database by margins ranging from 29.9% to 81.7%. For content creation, software development, scientific computing, or heavy multitasking, the 8945HX is the only logical choice between these two. Its 95th percentile standing confirms that it ranks among the fastest mobile CPUs available.

The Ryzen 5 7533HS is the better fit for a different set of priorities. Its 35-watt TDP allows for thinner, lighter, and quieter laptops with longer battery life. Its 73rd percentile places it above the majority of all tracked CPUs, so it is not a weak processor by any measure. For users who need a capable daily driver for office work, media consumption, and light productivity, the 7533HS delivers adequate performance with far less power draw. The PassMark single-thread gap of 29.9% means everyday responsiveness will be close, though not identical.

The choice depends on chassis design and workload, not on benchmark supremacy. The 8945HX demands a larger laptop with robust cooling to sustain its 55-watt envelope. The 7533HS fits into compact designs where thermal headroom is minimal. Neither processor is wrong; they serve different segments. The 8945HX is for those who need maximum compute in a mobile package. The 7533HS is for those who value portability and efficiency over raw output. The data cannot tell you which laptop you should buy, but it can tell you what each processor delivers. The 8945HX delivers top-tier performance. The 7533HS delivers competent performance with lower power requirements.
