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

The Verdict

The benchmark database positions these two processors at opposite ends of the performance spectrum despite both being 35 W parts. The Intel Core Ultra 9 285T wins all 17 recorded head-to-head comparisons, with an average benchmark score of 51310 versus 19364 for the AMD Ryzen 5 7533HS. The Intel part sits in the 91st percentile of all CPUs, while the AMD chip ranks in the 73rd percentile.

The Ryzen 5 7533HS is best suited for compact mobile systems where the 6-core, 12-thread configuration and integrated Radeon 660M graphics provide a balanced foundation for everyday workloads. Its nearest rivals in the database include the Intel Core Ultra 5 226V (average score 19368, 0% delta), the Intel Core i5-1345U (average score 19411, -0.2% delta), and the Intel Core i7-8700K (average score 19238, 0.7% delta). This places the Ryzen squarely in the mid-range mobile tier.

The Core Ultra 9 285T is a desktop-class part that belongs in a different league. Its 24 cores, 24 threads, and 36 MB of shared L3 cache produce results comparable to the Intel Core i9-14900T (average score 51015, 0.6% delta) and the Intel Core i9-13900F (average score 51730, -0.8% delta). The data clearly shows that the Core Ultra 9 285T is the choice for multi-threaded rendering, content creation, and heavy computational tasks.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 7533HS uses the Zen 3+ architecture under the Rembrandt-R codename, manufactured on a 6 nm TSMC process with a die size of 208 mm². It has 6 cores and 12 threads, with base and boost clocks of 3.30 GHz and 4.40 GHz respectively. The cache hierarchy consists of 64 KB L1 per core, 512 KB L2 per core, and 16 MB of shared L3. Memory support is dual-channel DDR5 with a bandwidth of 76.8 GB/s. The integrated graphics are Radeon 660M. The socket is AMD Socket FP7, and the market segment is mobile.

The Intel Core Ultra 9 285T uses the Arrow Lake architecture, specifically Arrow Lake-S, built on a 3 nm TSMC process with 17,800 million transistors and a die size of 243 mm². It has 24 cores and 24 threads, meaning no hyperthreading is present. Base clock is 1.40 GHz, but boost reaches 5.40 GHz. The cache layout is substantially larger: 192 KB L1 per core, 3 MB L2 per core, and 36 MB of shared L3. Memory bandwidth is rated at 102.4 GB/s over dual-channel DDR5, and ECC memory is supported. The integrated graphics are Arc Xe-LPG Graphics with 64 execution units. It uses Intel Socket 1851 and is a desktop part. PCIe support is Gen 5 with 20 lanes on the CPU side, versus Gen 4 with 20 lanes on the AMD part.

The process node difference is significant: 3 nm versus 6 nm. That, combined with the larger core count and cache pool, explains the massive performance gap in the recorded benchmarks. The Intel part also carries a launch MSRP of $549, which reflects its higher tier positioning.

Head-to-Head Benchmarks

The Core Ultra 9 285T dominates every single recorded benchmark. In Cinebench R23 multi-core, the Intel part scores 33573 against 12342 for the AMD, a delta of -63.2% from the AMD perspective. Single-core R23 shows 4739 versus 1742, also a -63.2% delta. The pattern holds across all Cinebench versions: R15 multi-core (3384 vs 1243, -63.3%), R15 single-core (477 vs 175, -63.3%), R20 multi-core (14100 vs 5183, -63.2%), and R20 single-core (1990 vs 731, -63.3%).

PassMark results reinforce the same conclusion. The largest gap appears in floating point math, where Intel scores 137923 versus 27800 for AMD, a -79.8% delta. Prime number finding shows an even wider relative gap at -86.1% (345 vs 48). Physics simulation follows at -71.1% (2842 vs 821). Data encryption shows a -66.6% delta (32061 vs 10718). Multi-thread performance is -63.6% (39931 vs 14520). Integer math is -61.6% (132433 vs 50800). Extended instructions are -59.2% (27477 vs 11219). Data compression is -56.1% (384140 vs 168692). Random string sorting is -63% (47695 vs 17669).

The narrowest margin is in single-thread performance, where the Intel part leads by -40.1% (4576 vs 2740). This is still a substantial advantage, but it is the closest the AMD chip comes to competitive parity. The data indicates the Core Ultra 9 285T excels in both aggregate throughput and per-thread execution, with the multi-thread advantage being slightly more pronounced than the single-thread edge.

Where Each One Wins

The Intel Core Ultra 9 285T wins every recorded benchmark, so the use-case analysis is about degree of dominance rather than alternative victories. The largest relative advantages appear in floating point math (-79.8%), prime number finding (-86.1%), and physics simulation (-71.1%). These results point toward workloads that stress raw arithmetic throughput and physical simulation, such as scientific computing, engineering analysis, and complex financial modeling.

The Core Ultra 9 285T also shows very strong multi-threaded performance, with a -63.6% delta in PassMark multi-thread and -63.2% to -63.3% deltas across all Cinebench multi-core tests. This makes it the clear choice for video rendering, 3D animation, batch image processing, and any workload that scales across many cores. Its 24 cores and 36 MB L3 cache provide ample parallelism for content creation pipelines.

For the AMD Ryzen 5 7533HS, the smallest gap is in single-thread performance at -40.1%. This means that in lightly threaded applications, such as web browsing, office productivity, and light coding, the AMD part is comparatively less disadvantaged, though still slower. The Ryzen's mobile segment designation and 35 W TDP make it appropriate for laptops and compact devices where the Core Ultra 9 285T's desktop socket and larger die would not fit.

The data also shows that the Core Ultra 9 285T's nearest rivals include the Core i9-14900T and Core i9-13900F, both within about 1% of its average score. The Ryzen 5 7533HS, by contrast, sits near the Core Ultra 5 226V and Core i5-1345U, confirming that these two processors occupy entirely different performance classes. Users seeking maximum multi-core throughput should look to the Intel part, while those constrained to mobile form factors with modest performance needs will find the AMD part adequate for general use.
