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

Head-to-Head Benchmarks

The benchmark data presents a decisive outcome: the Intel Core Ultra 7 265HX wins all 17 recorded head-to-head comparisons against the AMD Ryzen 5 7533HS. The average benchmark score for the Intel part is 63,173, while the AMD processor averages 19,364, placing the Intel chip in the 93rd percentile of all CPUs versus the AMD chip's 73rd percentile.

In Cinebench testing, the Intel Core Ultra 7 265HX dominates across every version. In Cinebench R15 multicore, the Intel processor scores 4,096 against the AMD chip's 1,243, a delta of -69.7 percent from the AMD perspective. The single-core R15 result follows the same pattern: 578 for Intel versus 175 for AMD, again a -69.7 percent delta. Cinebench R20 multicore shows Intel at 17,069 versus AMD at 5,183 (-69.6 percent), while R20 single-core records 2,409 versus 731 (-69.7 percent). The R23 multicore test puts Intel at 40,642 and AMD at 12,342 (-69.6 percent), with single-core R23 at 5,737 versus 1,742 (-69.6 percent). These deltas cluster tightly around -69.6 to -69.7 percent, indicating a consistent performance gap regardless of the Cinebench version or thread count.

PassMark tests reinforce the Intel advantage, though the margins vary by workload. The largest delta appears in PassMark find prime numbers, where Intel scores 406 versus AMD's 48, a -88.2 percent difference. Floating point math shows Intel at 161,605 versus AMD's 27,800 (-82.8 percent). Data encryption records Intel at 39,472 versus 10,718 (-72.8 percent), and extended instructions show 40,741 versus 11,219 (-72.5 percent). Physics testing gives Intel 2,978 versus AMD's 821 (-72.4 percent). Random string sorting lands at 62,458 versus 17,669 (-71.7 percent). Data compression shows 511,817 versus 168,692 (-67 percent), while integer math is the closest multicore comparison at 126,954 versus 50,800 (-60 percent). The smallest overall delta is in PassMark single-thread, where Intel scores 4,500 versus AMD's 2,740 (-39.1 percent).

The single-thread gap is notably smaller than the multicore gaps, suggesting the Intel architecture's clock speed advantage matters more in lightly threaded work, while the core-count disparity drives the larger multicore margins. The delta of -39.1 percent in single-thread remains substantial, but it is roughly half the magnitude of the typical -69 to -72 percent multicore deltas.

Architecture Differences

The two processors come from different design philosophies and manufacturing nodes. The AMD Ryzen 5 7533HS uses the Zen 3+ architecture under the Rembrandt-R codename, built on a 6 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.30 GHz and a boost clock of 4.40 GHz. The Intel Core Ultra 7 265HX uses the Arrow Lake architecture under the Arrow Lake-HX codename, built on a 3 nm process, also at TSMC. It has 20 cores and 20 threads, with a base clock of 2.60 GHz and a boost clock of 5.30 GHz.

The core and thread counts reveal a fundamental structural difference. AMD implements simultaneous multithreading, giving 12 threads from 6 cores. Intel does not implement hyper-threading here, so 20 cores map directly to 20 threads. Despite the lack of multithreading, the Intel part has more than three times the physical core count, which explains its multicore benchmark dominance.

Cache hierarchies differ substantially. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The Intel L3 cache is nearly double the AMD's shared pool, and its per-core L2 is six times larger.

Process node and die characteristics also separate the two. Intel's transistor count is listed at 17,800 million, while AMD's transistor count is not recorded. The Intel die measures 243 mm², compared to AMD's 208 mm². The Intel part uses a 3 nm node versus AMD's 6 nm node, which contributes to the Intel chip's higher transistor density.

Memory bandwidth differs as well. Both support DDR5 on a dual-channel bus, but Intel records 102.4 GB/s of memory bandwidth against AMD's 76.8 GB/s. PCIe capabilities also diverge: Intel provides Gen 5 with 20 lanes (CPU only), while AMD provides Gen 4 with 20 lanes (CPU only). Integrated graphics differ, with AMD using Radeon 660M and Intel using Arc Xe-LPG Graphics 64EU.

Power and thermal envelopes are not directly comparable in the recorded data, but the TDP figures show Intel at 55 watts versus AMD at 35 watts. The Intel part also has an unlocked multiplier, while the AMD processor does not.

Where Each One Wins

The recorded data shows no benchmark wins for the AMD Ryzen 5 7533HS. Every single head-to-head test favors the Intel Core Ultra 7 265HX. This is not a case of workloads splitting between the two; the Intel processor is faster in every measured category.

The closest competition occurs in PassMark single-thread, where Intel leads by -39.1 percent. This remains a significant margin, but it indicates the AMD chip is relatively less disadvantaged in lightly threaded scenarios. The AMD processor's 4.40 GHz boost clock, while lower than Intel's 5.30 GHz, still provides reasonable single-thread performance. The data suggests that for single-threaded applications, the Intel advantage is substantial but not overwhelming relative to its multicore lead.

The largest Intel wins appear in prime number finding (-88.2 percent) and floating point math (-82.8 percent). These workloads typically scale with core count and clock speed, both of which favor the Intel chip. The Intel architecture's higher core count, higher boost clock, and larger cache pool all contribute to these results.

For workloads involving data encryption, extended instructions, physics simulation, and random string sorting, the Intel lead ranges from -71.7 to -72.8 percent. These are consistently strong Intel advantages. Data compression shows a slightly smaller gap at -67 percent, and integer math shows the smallest multicore delta at -60 percent.

The AMD processor's 73rd percentile ranking places it among mid-range mobile processors, while the Intel chip's 93rd percentile places it near the top of the database. The nearest rivals for the AMD chip include the Intel Core Ultra 5 226V (delta 0 percent), the Intel Core i5-1345U (delta -0.2 percent), the Intel Core i7-8700K (delta 0.7 percent), and the Intel Core i7-10700F (delta -0.7 percent). The Intel chip's nearest rivals are the Intel Core i7-13790F (delta 0.1 percent), the AMD Ryzen AI 7 450G (delta -0.2 percent), the AMD Ryzen AI Embedded P185 (delta 0.5 percent), and the Intel Core Ultra 7 255HX (delta 0.7 percent). These rival groups illustrate the performance tier each processor occupies.
