AMD Ryzen 5 7533HS vs Intel Core Ultra 7 265H Comparison

The AMD Ryzen 5 7533HS and Intel Core Ultra 7 265H occupy different tiers within the mobile processor market, a distinction that is immediately apparent in the recorded benchmark data. The AMD part, built on the older Zen 3+ architecture, delivers a competent but modest performance profile. In stark contrast, the Intel Core Ultra 7 265H, with its newer Arrow Lake design, posts decisively higher scores across every single workload in the database. The data shows a complete sweep for the Intel processor, which holds the 88th percentile among all CPUs, while the AMD chip sits at the 73rd percentile. This creates a clear performance hierarchy, though the architectural and efficiency differences between the two units provide context beyond raw speed.

Where Each One Wins

The head-to-head benchmark results are unequivocal: the Intel Core Ultra 7 265H wins in every recorded test. The AMD Ryzen 5 7533HS does not secure a single victory across the 17 benchmark entries, which include Cinebench R15, R20, and R23, as well as the PassMark suite. For workloads such as multi-threaded rendering and CPU-bound physics simulations, the Intel part is the only viable option between the two. The data shows the Intel processor leading by substantial margins in every category, from encryption to random string sorting.

There is no use-case split based on benchmark wins because the AMD processor does not win anywhere. However, the recorded figures do reveal that the margin of victory varies significantly by workload. The Intel chip is closest in single-threaded Cinebench R23, where it leads by 16.2%, and furthest ahead in the PassMark prime number test, where it leads by 85.7%. This suggests that the Intel architecture has particular strength in integer-heavy and mathematical workloads, while its advantage in single-threaded tasks, though still decisive, is comparatively smaller.

Architecture Differences

The two processors come from different design generations and use different fabrication nodes. The AMD Ryzen 5 7533HS is a 7000 series mobile chip built on the Zen 3+ architecture, codenamed Rembrandt-R, and manufactured on a 6 nm process at TSMC. The Intel Core Ultra 7 265H belongs to the Core Ultra Series 2, uses the Arrow Lake architecture, codenamed Arrow Lake-H, and is built on a 3 nm process, also at TSMC. The newer 3 nm node gives the Intel chip a potential efficiency advantage, though the database does not include direct power consumption measurements.

Core configurations differ substantially. The AMD processor has 6 cores and 12 threads, indicating simultaneous multithreading. The Intel processor has 16 cores and 16 threads, which means it relies on a larger physical core count without hyperthreading. The Intel part also carries a significantly different cache layout, with 192 KB of L1 per core and 3 MB of L2 per core, compared to 64 KB and 512 KB per core on the AMD side. In L3 cache, the Intel chip has 24 MB shared, while the AMD chip has 16 MB shared. These differences explain why the Intel processor is able to sustain much higher throughput in multi-threaded workloads.

Memory support also diverges. The AMD chip supports DDR5 on a dual-channel bus with a recorded memory bandwidth of 76.8 GB/s. The Intel chip supports both DDR5 and LPDDR5X on a dual-channel bus, with a higher recorded memory bandwidth of 102.4 GB/s. The Intel chip also includes ECC memory support, which the AMD chip lacks. In terms of expansion, the AMD processor offers PCIe Gen 4 with 20 lanes, while the Intel processor offers PCIe Gen 5 with 8 lanes. The integrated graphics differ as well, with the AMD part using Radeon 660M and the Intel part using Arc Graphics 140T.

The processors also report different base and boost clocks. The AMD chip has a base clock of 3.30 GHz and a boost clock of 4.40 GHz, while the Intel chip has a base clock of 2.20 GHz and a boost clock of 5.30 GHz. The higher boost clock on the Intel part is consistent with its better single-threaded results. The thermal design power is lower on the Intel chip at 28 watts, compared to 35 watts for the AMD chip, which is notable given the Intel part's far higher benchmark scores.

Head-to-Head Benchmarks

In Cinebench R15 multicore, the Intel Core Ultra 7 265H scores 2989 against the AMD Ryzen 5 7533HS's 1243, a delta of 58.4%. The single-core R15 result shows a smaller but still large gap, with Intel at 307 and AMD at 175, a 43% difference. Moving to Cinebench R20, the multicore scores are 12131 for Intel and 5183 for AMD, again a 57.3% lead. The R20 single-core test shows Intel at 1712 against AMD's 731, another 57.3% delta.

Cinebench R23 produces the closest relative result in the entire benchmark set. The Intel chip scores 19940 in multicore, while the AMD chip scores 12342, a 38.1% difference. In R23 single-core, Intel posts 2080 versus AMD's 1742, a 16.2% lead. This single-core R23 margin is the smallest of any test, indicating that the Zen 3+ architecture remains competitive on a per-thread basis in this specific workload, though it still loses.

The PassMark suite reveals the largest gaps. In data compression, Intel scores 334711 against AMD's 168692, a 49.6% difference. Data encryption shows Intel at 26005 and AMD at 10718, a 58.8% delta. Extended instructions tests put Intel at 26805 and AMD at 11219, a 58.1% gap. The prime number test is the most lopsided, with Intel at 335 and AMD at 48, a striking 85.7% difference. Floating point math shows Intel at 109123 and AMD at 27800, a 74.5% delta. Integer math is closer but still decisive, with Intel at 85479 and AMD at 50800, a 40.6% gap.

The PassMark multithread score confirms the overall trend, with Intel at 34027 and AMD at 14520, a 57.3% difference. The physics test shows Intel at 2497 and AMD at 821, a 67.1% delta. Random string sorting puts Intel at 40742 and AMD at 17669, a 56.6% gap. Finally, the single-thread PassMark result, recorded twice in the database as both "single_thread" and "singlethread", shows Intel at 4334 and AMD at 2740, a 36.8% difference.

The average benchmark scores reinforce this hierarchy. The Intel Core Ultra 7 265H has an average score of 41621, while the AMD Ryzen 5 7533HS has an average score of 19364. The Intel chip's nearest rivals include the Intel Core 7 251TE, the Intel Core i7-14650HX, and the Intel Core i7-12850HX, all within a 0.4% range. The AMD chip's nearest rivals include the Intel Core Ultra 5 226V, the Intel Core i5-1345U, and the Intel Core i7-8700K. This places the two processors in entirely different performance classes.

The Verdict

The recorded data indicates that the Intel Core Ultra 7 265H is the superior processor in every measured workload. It outperforms the AMD Ryzen 5 7533HS by margins ranging from 16.2% in Cinebench R23 single-core to 85.7% in the PassMark prime number test. The Intel chip also achieves these results with a lower thermal design power of 28 watts against AMD's 35 watts, and it carries a higher percentile ranking at 88 versus 73.

The AMD processor does hold a few structural advantages. It offers 20 PCIe Gen 4 lanes against Intel's 8 PCIe Gen 5 lanes, and its 6 nm process, while older than Intel's 3 nm node, is still a modern manufacturing technology. The AMD chip also has a higher base clock of 3.30 GHz, which may benefit certain lightly threaded tasks that do not reach boost frequencies. However, none of these attributes translate into a benchmark victory in the database.

For workloads that demand high multi-threaded throughput, such as rendering, compilation, or data processing, the Intel Core Ultra 7 265H is the clear choice based on the data. For single-threaded responsiveness, the Intel chip still leads, though by a smaller margin. The AMD Ryzen 5 7533HS remains a functional mobile processor, and its performance is comparable to desktop parts like the Intel Core i7-8700K, but it cannot match the newer Intel architecture in any test recorded here.
