AMD Ryzen 5 7533HS vs Intel Core Ultra 9 275HX Comparison

Where Each One Wins

The recorded benchmark data shows a complete sweep for the Intel Core Ultra 9 275HX. Across all 17 head-to-head comparisons in the database, the Intel part finishes ahead, leaving the AMD Ryzen 5 7533HS without a single winning result. That does not mean the AMD chip has no role, but it does mean that in every measured workload, the Intel processor posts a higher score. The AMD Ryzen 5 7533HS sits at the 73rd percentile of all CPUs tested, while the Intel Core Ultra 9 275HX lands at the 94th percentile. That percentile gap of 21 points summarizes the competitive distance between them.

The use-case split is therefore about workload class rather than about any specific task favoring AMD. The Intel processor wins both single-threaded and multi-threaded tests, so there is no scenario in the data where the AMD part takes a category. The largest Intel advantages appear in floating-point math, prime number finding, and data encryption, where the deltas range from 77.2% to 89.3% in Intel's favor. The smallest Intel advantage is in Cinebench R23 single-core, where it leads by 21%. Even that "small" lead is substantial. For a user comparing these two, the decision is not about which workloads favor which chip, but rather about whether the AMD part's lower power envelope and smaller physical footprint matter more than the Intel part's overwhelming performance margin.

Architecture Differences

The two processors come from different architectural generations and different process nodes. The AMD Ryzen 5 7533HS uses Zen 3+ architecture, codenamed Rembrandt-R, built on a 6 nm process at TSMC. The Intel Core Ultra 9 275HX uses Arrow Lake architecture, codenamed Arrow Lake-HX, built on a 3 nm process, also at TSMC. The Intel die is larger at 243 mm² versus 208 mm² for AMD, and Intel lists 17,800 million transistors while AMD does not report a transistor count in the database.

Core counts differ sharply. The AMD chip has 6 cores and 12 threads, while the Intel chip has 24 cores and 24 threads. The Intel part does not use hyper-threading, so its thread count equals its core count. The AMD part doubles its thread count through simultaneous multithreading. Cache structures also differ. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The Intel L2 allocation is six times larger per core, and its L3 is more than double the AMD total.

Memory support is DDR5 for both, and both use a dual-channel memory bus. The Intel part has a higher memory bandwidth rating at 102.4 GB/s versus 76.8 GB/s for AMD. Neither supports ECC memory. PCIe connectivity differs by generation: AMD uses Gen 4 with 20 CPU lanes, while Intel uses Gen 5 with 20 CPU lanes. The integrated graphics also differ. AMD pairs its chip with Radeon 660M, while Intel uses Arc Xe-LPG Graphics 64EU.

Clock speeds move in opposite directions. The AMD chip has a 3.30 GHz base clock and a 4.40 GHz boost clock. The Intel chip has a 2.70 GHz base clock and a 5.40 GHz boost clock. The Intel part boosts 1.0 GHz higher but idles at a lower base. Power envelopes differ too: AMD is rated at 35 W TDP, Intel at 55 W TDP. The Intel part also has an unlocked multiplier, while the AMD part is locked. Both use mobile sockets, AMD Socket FP7 for AMD and Intel BGA 2114 for Intel. The AMD release date is 2024-08-31, and the Intel release date is 2025-01-12.

Head-to-Head Benchmarks

The Cinebench suite shows the scale of the Intel advantage. In Cinebench R15 multi-core, Intel scores 5619.5 against AMD's 1243, a delta of 77.9% in Intel's favor. In R15 single-core, Intel scores 334 against 175, a 47.6% lead. Cinebench R20 multi-core shows Intel at 19899 versus 5183, a 74% gap, and R20 single-core shows Intel at 2809 versus 731, also a 74% gap. Cinebench R23 multi-core gives Intel 35589 versus 12342, a 65.3% lead, while R23 single-core gives Intel 2204 versus 1742, the slimmest margin at 21%.

PassMark results follow the same pattern. Data compression favors Intel at 608381 versus 168692, a 72.3% lead. Data encryption favors Intel at 47112 versus 10718, a 77.2% lead. Extended instructions favor Intel at 47016 versus 11219, a 76.1% lead. Prime number finding shows the largest gap: Intel at 448 versus AMD at 48, an 89.3% delta. Floating-point math shows Intel at 191186 versus 27800, an 85.5% delta. Integer math favors Intel at 155218 versus 50800, a 67.3% lead. The PassMark multi-thread score is 55759 for Intel versus 14520 for AMD, a 74% gap. Physics shows 3338 versus 821, a 75.4% lead, and random string sorting shows 74320 versus 17669, a 76.2% lead. Single-thread PassMark gives Intel 4713 versus 2740, a 41.9% lead, and the duplicate singlethread test confirms the same numbers.

The database also includes Geekbench scores for Intel only: 20795 multi-core and 2458 single-core. AMD has no Geekbench entries in the recorded data, so a direct comparison there is not possible. The average benchmark score tells the broader story: Intel averages 67469 across its tests, while AMD averages 19364. That is a 348% difference in average score, driven by the Intel part's consistent dominance across both integer and floating-point workloads.

The Verdict

The data points to one direction. The Intel Core Ultra 9 275HX wins every recorded benchmark against the AMD Ryzen 5 7533HS. Its smallest lead is 21% in Cinebench R23 single-core, and its largest is 89.3% in PassMark prime number finding. The average benchmark score difference is 348% in Intel's favor. The Intel part also holds a higher percentile ranking, 94th versus 73rd, and sits alongside workstation-class processors in its nearest rival list, including the Intel Xeon w5-3525, AMD EPYC 4484PX, AMD Ryzen Threadripper PRO 5955WX, and Intel Xeon 6515P. The AMD part sits alongside mid-range desktop and mobile chips like the Intel Core Ultra 5 226V and Intel Core i5-1345U.

For a user who needs maximum compute throughput, whether single-threaded or multi-threaded, the Intel Core Ultra 9 275HX is the clear choice based on the recorded scores. The AMD Ryzen 5 7533HS offers a lower 35 W TDP, a smaller die, and a lower boost clock, which suggests lighter cooling requirements, but the database does not contain any benchmark where that translates into a performance win. The Intel part consumes more power at 55 W TDP, but it delivers more than double the multi-threaded Cinebench scores and roughly 71% higher single-threaded PassMark scores. For a mobile workstation or a high-performance laptop, the Intel chip is the one the data supports. For a thin-and-light system where the 35 W TDP and smaller physical footprint matter, the AMD chip remains a viable option, but only in the context of power-constrained designs, not in terms of raw benchmark performance.
