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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the Intel Core Ultra 7 265KF wins all 17 head-to-head benchmark comparisons against the AMD Ryzen 5 7533HS. No single test favors the AMD part, and the margin is consistently large across every workload category.

In Cinebench rendering tests, the Intel processor dominates by a uniform delta of -75.2% in each case. The R15 multicore test shows 5013 points for Intel versus 1243 for AMD, while R15 singlecore delivers 707 versus 175. The R20 results follow the same pattern: 20889 against 5183 in multicore, and 2948 against 731 in singlecore. The R23 suite shows the largest absolute gap, with Intel scoring 49736 in multicore and 7021 in singlecore, compared to AMD's 12342 and 1742 respectively.

The PassMark suite reveals where the delta varies most. The narrowest margin appears in single-threaded work: the Intel chip scores 4928 versus AMD's 2740, a -44.4% difference. Integer math shows a -64.6% delta (143351 versus 50800), while multithread performance sits at -75.2% (58518 versus 14520). The widest gap is in prime number searching, where Intel's 486 crushes AMD's 48, a -90.1% delta. Floating-point math shows Intel at 189431 against AMD's 27800 (-85.3%), and extended instructions deliver 54513 versus 11219 (-79.4%). Data compression, encryption, random string sorting, and physics all fall in the -74.7% to -77.8% range.

The average benchmark score tells the same story: the Intel part records 71910 across all recorded tests, while the AMD chip averages 19364. That puts the Intel processor in the 94th percentile of all CPUs in the database, versus the 73rd percentile for the AMD part.

Where Each One Wins

The benchmark results indicate that the Intel Core Ultra 7 265KF wins in every measured scenario, so the use-case split is defined by the magnitude of the advantage rather than any reversal.

For single-threaded responsiveness, the Intel chip leads by the smallest margin in the entire comparison, yet still holds a 44.4% advantage. This covers tasks like light office work, web browsing, and application launching where a single core carries most of the load. The AMD Ryzen 5 7533HS remains functional in these tasks, but the data shows it trails by nearly half.

In heavily parallel workloads, the gap widens substantially. Rendering, video encoding, and scientific computing that scale across many threads will favor the Intel part by roughly three to four times the performance, depending on the specific instruction mix. The Cinebench R23 multicore result of 49736 versus 12342 represents a 4x advantage in raw rendering throughput.

For integer-heavy and floating-point-heavy compute, the Intel processor maintains a 64.6% and 85.3% lead respectively. Prime number searching shows the most extreme difference at 90.1%, indicating workloads with tight loops and branch-heavy logic will see the largest relative gains from the Intel architecture.

The AMD chip's only niche is its power profile. With a 35 watt TDP against Intel's 125 watt TDP, the Ryzen 5 7533HS fits into thin-and-light mobile designs where thermal headroom is minimal. The data does not record any performance test where this efficiency translates into a win, but the lower power draw makes it viable in form factors that the desktop-bound Intel part cannot occupy.

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, built on a 6 nm process at TSMC. It belongs to the 7000 series and the Ryzen 5 generation, with a die size of 208 mm². The Intel Core Ultra 7 265KF employs the Arrow Lake architecture under the Arrow Lake-S codename, fabricated on a 3 nm process at TSMC, and carries a die size of 243 mm² with 17,800 million transistors.

Core configuration differs sharply. The AMD part has 6 cores and 12 threads, meaning each core supports two threads via SMT. The Intel part has 20 cores and 20 threads, indicating no simultaneous multithreading and a larger physical core count. This partly explains the multicore performance gap: the Intel chip has over three times the cores, and each core runs at a higher clock speed.

Cache hierarchies are also distinct. The AMD processor allocates 64 KB of L1 per core and 512 KB of L2 per core, with 16 MB of shared L3. The Intel processor provides 192 KB of L1 per core and 3 MB of L2 per core, with 30 MB of shared L3. The Intel chip's larger per-core caches and nearly double the L3 capacity give it more headroom for data reuse in compute-heavy loops.

The integrated graphics situation is one-sided. The AMD Ryzen 5 7533HS includes a Radeon 660M iGPU, while the Intel Core Ultra 7 265KF has no integrated graphics at all (listed as N/A). This makes the AMD part a complete package for a mobile system without a discrete GPU, whereas the Intel desktop chip requires an external graphics card for any display output.

The memory controllers are similar in channel configuration but differ in bandwidth. Both support DDR5 with dual-channel buses, but the Intel part records 102.4 GB/s against AMD's 76.8 GB/s. PCIe connectivity also differs: the AMD chip uses Gen 4 with 20 lanes, while the Intel chip uses the newer Gen 5 standard with 20 lanes.
