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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the Intel Core Ultra 9 285HX across the entire benchmark suite. Out of 17 head-to-head comparisons, the Intel processor wins 17, with the AMD Ryzen 5 7533HS recording zero wins. The margins are substantial, though they vary considerably by workload type.

The largest gap appears in the PassMark find prime numbers test. The Intel chip scores 460 versus 48 for the AMD part, a delta of -89.6%. This indicates an extreme disparity in integer-heavy algorithmic workloads. Floating point math also shows a massive divide, with Intel scoring 194998 against 27800, a -85.7% delta. The AMD processor trails by more than 85% in both of these compute-intensive tests.

Cinebench multi-core results tell a similar story. In Cinebench R15 multi-core, Intel delivers 5656.5 against AMD's 1243, a -78% delta. The R20 multi-core test shows Intel at 20236 versus 5183, a -74.4% gap. In R23 multi-core, Intel scores 36429.5 compared to 12342, a -66.1% delta. These results consistently show Intel holding an advantage of roughly two-thirds to three-quarters in multi-threaded rendering workloads.

Single-core differences are smaller but still favor Intel. In Cinebench R23 single-core, Intel scores 2187.5 against 1742, a -20.4% delta. The R15 single-core test shows Intel at 323.5 versus 175, a -45.9% gap. The R20 single-core result mirrors the multi-core gap at -74.4%, with Intel at 2856 and AMD at 731. PassMark single-thread scores show Intel at 4618 against 2740, a -40.7% delta.

Data compression and encryption workloads also favor Intel heavily. PassMark data compression shows Intel at 631885 versus 168692, a -73.3% delta. Data encryption shows Intel at 48567 against 10718, a -77.9% delta. Extended instructions testing gives Intel 49148 versus 11219, a -77.2% delta. Random string sorting completes the pattern, with Intel at 77196 against 17669, a -77.1% delta.

The multithread score in PassMark places Intel at 56902 versus 14520, a -74.5% delta. Physics simulation shows Intel at 3476 against 821, a -76.4% gap. Integer math gives Intel 155076 versus 50800, a -67.2% delta. The narrowest margin across all tests is the Cinebench R23 single-core result at -20.4%, while the widest is the find prime numbers test at -89.6%.

Where Each One Wins

The Intel Core Ultra 9 285HX wins in every measured category, but the magnitude of its advantage varies by workload type, which informs how each processor should be positioned.

For heavily parallel workloads that scale with core count, such as 3D rendering in Cinebench, Intel's advantage is enormous. The R15 multi-core result places Intel at nearly 4.6 times the AMD score. The R23 multi-core gap, while still large at -66.1%, is the smallest multi-core delta in the suite, suggesting that the AMD part's efficiency becomes relatively less disadvantaged in longer-running sustained loads.

Single-threaded performance shows the closest competition. The R23 single-core delta of -20.4% is the second-smallest margin overall. PassMark single-thread shows a -40.7% gap. This indicates that for lightly threaded tasks like everyday desktop responsiveness, basic office work, or legacy software that relies on one core, the gap narrows considerably, though Intel still leads.

The AMD Ryzen 5 7533HS operates in a different performance class entirely. Its 73rd percentile ranking among all CPUs versus Intel's 95th percentile confirms this. The average benchmark score for AMD sits at 19364, while Intel reaches 76155, roughly 3.9 times higher. The nearest rivals for AMD include the Intel Core Ultra 5 226V at 19368 and the Intel Core i7-8700K at 19238, which shows the AMD part competing with older desktop processors rather than modern flagship mobile parts. Intel's nearest rivals are the AMD Ryzen 9 8945HX at 76212 and the AMD Ryzen Threadripper PRO 9945WX at 76513, placing it in the company of high-end desktop and workstation processors.

The data supports a clear split: AMD serves efficiency-oriented mobile workloads where its 35W TDP and 6-core design fit thin-and-light laptops, while Intel targets maximum performance in large mobile workstations and gaming laptops where its 55W TDP and 24-core configuration can be fed adequately.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses the Zen 3+ architecture on a 6 nm TSMC process, with the codename Rembrandt-R. Intel uses Arrow Lake, specifically Arrow Lake-HX, on a 3 nm TSMC process. The process node difference alone explains a significant portion of the performance gap, as Intel packs far more transistors into a slightly larger die.

AMD's Ryzen 5 7533HS has 6 cores and 12 threads, relying on simultaneous multithreading to reach its thread count. Intel's Core Ultra 9 285HX has 24 cores and 24 threads, with no hyperthreading, meaning each core contributes exactly one thread. The core count difference of 18 cores is the single largest architectural disparity between these parts.

Cache configurations differ substantially. AMD provides 64 KB of L1 per core and 512 KB of L2 per core, with 16 MB of shared L3 cache. Intel provides 192 KB of L1 per core and 3 MB of L2 per core, with 36 MB of shared L3. The larger per-core L2 cache on Intel, combined with more than double the shared L3, gives it a considerable advantage in workloads that benefit from caching.

The die sizes reflect these differences. AMD's die measures 208 mm², while Intel's measures 243 mm². Intel's transistor count is listed at 17,800 million, a figure AMD does not report. Both use TSMC as the foundry, but on different process nodes.

Memory support shows both processors using DDR5 with dual-channel buses. However, Intel's memory bandwidth reaches 102.4 GB/s versus AMD's 76.8 GB/s, a 33% advantage. Intel also supports ECC memory, while AMD does not. PCIe connectivity differs, with AMD offering Gen 4 with 20 CPU lanes and Intel offering Gen 5 with 20 CPU lanes.

Integrated graphics differ as well. AMD uses the Radeon 660M, while Intel uses Arc Xe-LPG Graphics with 64 execution units. Both target mobile segments, but the Intel part's integrated GPU is paired with a much faster CPU complex.

Clock speeds show an interesting trade-off. AMD has a higher base clock at 3.30 GHz versus Intel's 2.80 GHz, but Intel's boost clock reaches 5.50 GHz versus AMD's 4.40 GHz. The boost behavior reflects Intel's ability to scale up under load when power and thermals allow.

The Verdict

The data presents an unambiguous performance hierarchy. The Intel Core Ultra 9 285HX outperforms the AMD Ryzen 5 7533HS in all 17 recorded benchmarks, with deltas ranging from -20.4% in Cinebench R23 single-core to -89.6% in PassMark find prime numbers. The Intel processor holds the 95th percentile among all CPUs, while AMD sits at the 73rd percentile.

The AMD Ryzen 5 7533HS competes most closely with mid-range processors like the Intel Core Ultra 5 226V and the Intel Core i7-8700K, based on average benchmark scores. Its 35W TDP and 6-core design place it firmly in the efficient mobile segment. The Intel Core Ultra 9 285HX, with its 55W TDP and 24-core design, aligns with the AMD Ryzen 9 8945HX and AMD Ryzen Threadripper PRO 9945WX in the database, indicating a high-end mobile workstation class.

Users who need maximum multi-threaded performance for rendering, simulation, or heavy data processing should select the Intel part. The data shows it delivers roughly three to four times the throughput in most multi-core tests. Users who prioritize efficiency and lighter workloads may find the AMD part adequate, particularly given its lower TDP, but the benchmark data confirms that even in single-threaded tasks, Intel maintains a lead of at least 20%.
