Architecture Differences

The AMD Ryzen 5 7533HS belongs to the 7000 series, built on the Zen 3+ architecture with the Rembrandt-R codename. It is manufactured by TSMC on a 6 nm process with a die size of 208 mm². The chip has 6 cores and 12 threads, relying on simultaneous multithreading to reach that thread count. Each core gets 64 KB of L1 cache and 512 KB of L2 cache, with 16 MB of shared L3 cache. The integrated graphics are Radeon 660M. The processor uses AMD Socket FP7 and has a 35 W TDP. Its base clock is 3.30 GHz with a boost clock of 4.40 GHz. The multiplier is locked, meaning overclocking is not supported.

The Intel Core Ultra 7 255HX comes from Core Ultra Series 2, built on the Arrow Lake architecture with the Arrow Lake-HX codename. It is also manufactured by TSMC, but on a 3 nm process, and the die size is 243 mm² with 17,800 million transistors. This chip has 20 cores and 20 threads, with no SMT enabled. Each core receives 192 KB of L1 cache and 3 MB of L2 cache, with 30 MB of shared L3 cache. The integrated graphics are Arc Xe-LPG Graphics 64EU. The processor uses Intel BGA 2114 and has a 55 W TDP. Its base clock is 2.40 GHz with a boost clock of 5.20 GHz. The multiplier is unlocked, allowing user-controlled overclocking.

The cache hierarchy differs substantially. The Intel chip has 3 times the L1 cache per core (192 KB vs 64 KB) and 6 times the L2 cache per core (3 MB vs 512 KB). The shared L3 cache is also larger on the Intel part, 30 MB versus 16 MB. The memory bandwidth favors Intel as well, at 102.4 GB/s versus 76.8 GB/s, even though both use dual-channel DDR5.

The PCIe generation is a notable difference. The AMD chip supports PCIe Gen 4 with 20 CPU lanes, while the Intel chip supports PCIe Gen 5 with 20 CPU lanes. Neither chip supports ECC memory. The AMD part has a production status of Active and was released on 2024-08-31, while the Intel part is also Active and was released on 2025-01-12.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 7 255HX outperforms the AMD Ryzen 5 7533HS in every measured workload, with multi-threaded tests showing the largest gaps. The Intel chip's 20 cores and 30 MB of L3 cache provide substantial headroom for parallel tasks, while its higher boost clock of 5.20 GHz supports strong single-thread results.

The AMD Ryzen 5 7533HS occupies a lower performance tier, with a 35 W TDP and 6 cores. Its strengths lie in a more modest power envelope, which may suit thinner mobile designs, but the benchmark results show no category where it leads the Intel part. The AMD chip's single-core score in Cinebench R23 is 1742, which is close enough to the Intel chip's 2163 to remain usable for everyday tasks, but the multi-core gap of over 60% in most tests is decisive for content creation or compilation workloads.

The Intel Core Ultra 7 255HX also offers an unlocked multiplier, so users who can manage the 55 W TDP may push performance further. The AMD chip is locked. The Intel part's PCIe Gen 5 support and higher memory bandwidth of 102.4 GB/s provide additional platform-level advantages over the AMD chip's PCIe Gen 4 and 76.8 GB/s.

For users prioritizing maximum throughput in mobile workstations, the Intel Core Ultra 7 255HX is the clear choice based on the recorded data. For users prioritizing lower power draw and a smaller core count, the AMD Ryzen 5 7533HS remains a functional option, but it will trail the Intel chip in every benchmark category. The database confirms that the Intel part delivers roughly 3.2 times the average benchmark score of the AMD part, a gap that no workload in the recorded results narrows to less than 19.5%.
