AMD Ryzen 5 7533HS vs Intel Core Ultra 9 285K Comparison

Head-to-Head Benchmarks

The benchmark data for this pairing is unambiguous. Across all 17 recorded comparisons, the Intel Core Ultra 9 285K takes the win, with no single test favoring the AMD Ryzen 5 7533HS. The average benchmark score of 83,807 for the Intel part versus 19,364 for the AMD part places them in different performance strata entirely.

The largest single-core gap appears in Cinebench R20 single-core, where the Intel chip scores 3,388 against the AMD chip's 731, a delta of -78.4 percent. Cinebench R15 single-core shows a similar story with 359 versus 175, a -51.3 percent difference. The Cinebench R23 single-core test narrows that gap somewhat: Intel scores 2,377, AMD scores 1,742, a -26.7 percent delta. That remains a substantial margin, but it is the closest any benchmark comes between the two in single-threaded work.

Multi-core results widen the chasm dramatically. Cinebench R23 multi-core sees the Intel part post 42,522 versus 12,342 for the AMD chip, a -71 percent delta. Cinebench R20 multi-core records 24,003 versus 5,183, a -78.4 percent gap, and Cinebench R15 multi-core shows 6,494 versus 1,243, a -80.9 percent delta. The pattern holds across PassMark's suite: integer math scores 172,379 versus 50,800 (-70.5 percent), floating point math 224,324 versus 27,800 (-87.6 percent), and extended instructions 62,277 versus 11,219 (-82 percent). Data compression shows 790,052 versus 168,692 (-78.6 percent), while encryption hits 57,745 versus 10,718 (-81.4 percent). Random string sorting records 94,927 versus 17,669 (-81.4 percent). Prime number finding is the most lopsided test: 541 versus 48, a -91.1 percent delta.

PassMark multithread scores reinforce the trend: 67,260 for Intel versus 14,520 for AMD, a -78.4 percent difference. Physics tests show 3,938 versus 821, a -79.2 percent gap. Single-thread PassMark results are closer but still decisively Intel: 5,087 versus 2,740, a -46.1 percent delta.

The percentile placement reflects this split. The Ryzen 5 7533HS sits at the 73rd percentile among all CPUs in the database, while the Core Ultra 9 285K lands at the 96th percentile. The AMD chip's nearest rivals in the database are all Intel parts: the Core Ultra 5 226V (average score 19,368, delta 0 percent), the Core i5-1345U (19,411, delta -0.2 percent), the Core i7-8700K (19,238, delta 0.7 percent), and the Core i7-10700F (19,499, delta -0.7 percent). The Intel chip's closest neighbors are the Core Ultra 9 290K Plus (84,003, delta -0.2 percent), AMD EPYC 4584PX (83,090, delta 0.9 percent), AMD EPYC 9135 (82,980, delta 1 percent), and AMD EPYC 7F72 (85,072, delta -1.5 percent). The AMD mobile processor competes with older desktop parts from several generations back; the Intel flagship trades blows with server-class EPYC silicon.

Architecture Differences

The two processors come from entirely different design lineages. The AMD Ryzen 5 7533HS uses the Zen 3+ architecture on the Rembrandt-R codename, built on a 6 nm TSMC process with a die size of 208 mm². The Intel Core Ultra 9 285K uses Arrow Lake-S, a 3 nm TSMC design with a die size of 243 mm² and a transistor count of 17,800 million. The AMD part reports no transistor figure in the database.

Core configurations differ profoundly. The Ryzen 5 7533HS has 6 cores and 12 threads, while the Core Ultra 9 285K has 24 cores and 24 threads. This is a key distinction: the Intel chip offers no simultaneous multithreading, relying on raw core count instead, while the AMD chip doubles its threads through SMT. Despite that, the thread count advantage sits firmly with Intel at 24 versus 12.

Cache hierarchies also diverge. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel chip features 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The larger per-core L1 and L2 allocations on the Intel part, combined with more than double the L3 capacity, feed its higher core count and clock speeds.

Clock speeds tell a similar story. The AMD chip runs at a 3.30 GHz base and 4.40 GHz boost. The Intel chip has a 3.70 GHz base and 5.70 GHz boost. Both are unlocked in different ways: the AMD part has a locked multiplier, while the Intel part has an unlocked multiplier, enabling overclocking.

Memory support is DDR5 on both, with dual-channel buses, but bandwidth differs: 76.8 GB/s on the AMD chip versus 102.4 GB/s on the Intel chip. ECC memory support also differs, with the AMD part lacking it and the Intel part supporting it. PCIe connectivity shows the generation gap: the AMD chip uses Gen 4 with 20 CPU lanes, while the Intel chip uses Gen 5 with 20 CPU lanes.

Integrated graphics differ as well. The AMD Ryzen 5 7533HS carries a Radeon 660M, while the Intel Core Ultra 9 285K carries Arc Xe-LPG Graphics with 64 execution units. Both are active production parts, but they target different sockets: AMD Socket FP7 for the mobile chip, Intel Socket 1851 for the desktop chip. The AMD part's release date is August 31, 2024; the Intel part's is October 23, 2024. The Intel part has a launch MSRP of $589.

The Verdict

The data points to a clear segmentation. The AMD Ryzen 5 7533HS is a mobile processor, built for low-power systems with a 35 W TDP, 6 cores, and a 73rd percentile standing. Its benchmark profile places it alongside desktop CPUs from the Intel Core i7-8700K and Core i7-10700F era, which are its nearest rivals in average score. That context matters: the chip competes with older desktop parts, not with current flagships.

The Intel Core Ultra 9 285K is a desktop flagship with a 125 W TDP, 24 cores, and a 96th percentile rank. Its nearest rivals include server processors from AMD's EPYC lineup, which indicates the performance tier it occupies. The launch MSRP of $589 positions it as a top-tier desktop part, though the database records no comparable price for the AMD chip.

For workloads that demand maximum multi-threaded throughput, the Intel part wins decisively in every recorded test. For single-threaded responsiveness, the Intel chip also leads, though the margin is smaller in Cinebench R23 single-core (-26.7 percent) and PassMark single-thread (-46.1 percent). The AMD chip's advantage lies in its mobile form factor and lower TDP, not in raw performance. Users constrained to a laptop platform have no choice but the Ryzen 5 7533HS; users building a high-end desktop have no reason to select it over the Core Ultra 9 285K based on the benchmark data. The architecture differences, cache sizes, clock speeds, and PCIe generation all favor the Intel part. The AMD chip holds its own only in the context of its power envelope and mobile market segment.
