AMD Ryzen 5 7533HS vs AMD Ryzen 9 9900X3D Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity: the AMD Ryzen 9 9900X3D wins all 17 head-to-head benchmark comparisons. The Ryzen 5 7533HS does not register a single victory. The scale of the margin varies by workload, but the direction is consistent across every test.

In Cinebench, the desktop part dominates. The R15 multicore result shows 4811 for the 9900X3D against 1243 for the 7533HS, a delta of -74.2% from the mobile chip’s perspective. The R15 singlecore test repeats the exact same percentage gap: 679 versus 175, again -74.2%. The R20 runs show the same pattern, with the 9900X3D scoring 20049 multicore and 2830 singlecore, versus 5183 and 731 for the 7533HS, deltas of -74.1% and -74.2% respectively. R23 multicore delivers 47737 against 12342, a -74.1% difference, while R23 singlecore shows 6739 versus 1742, a -74.2% gap.

The PassMark suite reveals where the largest relative losses occur. The steepest delta appears in `find_prime_numbers`: the 9900X3D scores 544, the 7533HS scores 48, a -91.2% difference. That is the single biggest proportional gap in the entire comparison. The `extended_instructions` test also shows a severe margin, with 55426 versus 11219, a -79.8% delta. `physics` follows at -84.6% (5340 versus 821). Floating point math shows 119622 versus 27800, a -76.8% gap. Data compression delivers 685074 versus 168692, a -75.4% delta, and random string sorting matches that exact -75.4% figure with 71864 versus 17669. Integer math scores 179727 against 50800, a -71.7% gap. Multithread performance shows 56154 versus 14520, a -74.1% delta. Data encryption shows the smallest proportional loss among the PassMark tests: 33282 versus 10718, a -67.8% gap.

The single-thread comparisons are the closest in relative terms. The 9900X3D scores 4646 in PassMark single-thread, against 2740 for the 7533HS, a -41% delta. That is the narrowest margin recorded in any test, yet it still represents a substantial lead for the desktop processor.

The average benchmark score places the 9900X3D at 54762, while the 7533HS sits at 19364. The 9900X3D lands in the 91st percentile of all CPUs in the database, whereas the 7533HS ranks in the 73rd percentile. In the nearest rival comparisons, the 7533HS is effectively matched with the Intel Core Ultra 5 226V (delta 0%), slightly behind the Intel Core i5-1345U (-0.2%), and slightly ahead of the Intel Core i7-8700K (+0.7%) and Intel Core i7-10700F (-0.7%). The 9900X3D sits just ahead of the Intel Core Ultra 5 245KF (-0.6%) and Intel Core Ultra 5 245K (+1.3%), and ahead of the Intel Xeon 6505P (+2%) and Intel Core i7-14700F (+2.1%).

The Verdict

The data separates these two processors by function and market segment. The Ryzen 5 7533HS is a mobile part with a 35 W TDP, designed for systems where power draw and thermals are constrained. The Ryzen 9 9900X3D is a desktop part with a 120 W TDP, built for maximum compute throughput. The benchmark results reflect that division.

For multi-threaded rendering, scientific simulation, video encoding, or any workload that scales across cores, the 9900X3D delivers roughly four times the performance. The Cinebench R23 multicore score of 47737 versus 12342 means a render that takes one hour on the 9900X3D would take approximately four hours on the 7533HS, assuming perfect linear scaling. The PassMark multithread result (56154 versus 14520) reinforces the same conclusion: the desktop chip is the only rational choice for sustained parallel workloads.

For single-thread performance, the gap narrows but remains decisive. A 4646 PassMark single-thread score versus 2740 means the 9900X3D is about 70% faster in lightly threaded tasks. That difference affects everyday responsiveness, application launch times, and legacy software that cannot use many cores.

The 7533HS is the appropriate selection only when the platform requires a mobile processor. Its 6 cores and 12 threads, combined with a 35 W TDP, suit thin-and-light laptops where battery life and cooling capacity are priorities. The integrated Radeon 660M graphics provide a functional display output without a discrete GPU. The 9900X3D, by contrast, requires a desktop AM5 motherboard, a dedicated cooling solution for its 120 W TDP, and a discrete GPU for display output (its integrated Radeon Graphics is not intended for gaming workloads).

The percentile data confirms the positioning. The 9900X3D sits at the 91st percentile among all CPUs, placing it comfortably in the high-performance tier. The 7533HS at the 73rd percentile is a solid mid-range mobile part, but it is not competing in the same performance class. Users who need the 9900X3D’s throughput must accept the desktop form factor and power requirements. Users who need the 7533HS’s portability must accept a fourfold reduction in multi-threaded throughput.

Specification Differences

The two processors differ on every core specification. The 7533HS has 6 cores and 12 threads, while the 9900X3D has 12 cores and 24 threads. Base clock rates are 3.30 GHz for the 7533HS and 4.40 GHz for the 9900X3D. Boost clocks are 4.40 GHz and 5.50 GHz respectively. TDP ratings are 35 W for the mobile part and 120 W for the desktop part.

The sockets are incompatible: the 7533HS uses AMD Socket FP7, while the 9900X3D uses AMD Socket AM5. The 7533HS is a mobile-market part; the 9900X3D is a desktop-market part. The 7533HS has a locked multiplier, while the 9900X3D has an unlocked multiplier. The 7533HS uses 20 PCIe Gen 4 lanes (CPU only), while the 9900X3D uses 24 PCIe Gen 5 lanes (CPU only).

Memory bandwidth differs: 76.8 GB/s for the 7533HS versus 89.6 GB/s for the 9900X3D. ECC memory support is absent on the 7533HS and present on the 9900X3D. The 7533HS has a die size of 208 mm², whereas the 9900X3D has two dies of 70.6 mm² each. The 9900X3D’s transistor count is recorded at 16,630 million; no transistor count is listed for the 7533HS.

The 9900X3D has a launch MSRP of $599. The 7533HS has no recorded launch MSRP in the database.

Architecture Differences

The architectural gap is generational and structural. The 7533HS uses Zen 3+ architecture with the Rembrandt-R codename, part of the 7000 series. The 9900X3D uses Zen 5 with the Granite Ridge codename, part of the 9000 series. The process node differs: 6 nm for the 7533HS, 4 nm for the 9900X3D, both fabricated by TSMC.

The cache hierarchy diverges significantly. The 7533HS has 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The 9900X3D has 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The 9900X3D’s L3 cache is eight times larger, which directly benefits workloads with large working sets that reuse data frequently.

The 9900X3D’s Zen 5 architecture also brings a higher boost clock (5.50 GHz versus 4.40 GHz) and a higher base clock (4.40 GHz versus 3.30 GHz). The desktop part’s 120 W TDP allows those clocks to be sustained, whereas the 35 W TDP of the mobile part forces lower sustained frequencies under load.

The memory controller differs in bandwidth capacity, as recorded: 89.6 GB/s versus 76.8 GB/s. Both support DDR5 and dual-channel operation. The PCIe interface also advances: Gen 5 with 24 lanes on the 9900X3D, against Gen 4 with 20 lanes on the 7533HS.

The 9900X3D’s dual-die design (2x 70.6 mm²) reflects a chiplet approach, while the 7533HS uses a monolithic 208 mm² die. The transistor count of 16,630 million on the 9900X3D indicates a substantially more complex design. The 7533HS’s integrated graphics are specified as Radeon 660M, while the 9900X3D lists only Radeon Graphics without a specific model designation. Both processors are currently active in production and support DDR5 memory, but they target completely different platforms: mobile FP7 versus desktop AM5.
