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

Head-to-Head Benchmarks

The benchmark data in this comparison is decisively one-sided. The Intel Core Ultra 7 265K wins all 17 recorded head-to-head tests, with the AMD Ryzen 5 7533HS trailing by margins that range from moderate to overwhelming. The largest gap appears in the PassMark find prime numbers test, where the Intel chip scores 491 against 48, a delta of -90.2% for AMD. That test measures integer-heavy prime calculation, and the result indicates a fundamental throughput advantage for the desktop part.

The Cinebench suite shows a consistent pattern. In Cinebench R15 multicore, Intel scores 5020 against AMD's 1243, a -75.2% delta. The R15 singlecore test is nearly identical in proportional terms: 708 versus 175, again -75.3%. Cinebench R20 follows the same trajectory, with Intel at 20918 multicore and 2953 singlecore, against AMD's 5183 and 731, both at -75.2%. The R23 multicore test narrows the proportional gap slightly, with Intel at 35850 and AMD at 12342, a -65.6% delta. The R23 singlecore test is the closest relative result in the entire set: Intel scores 2020, AMD scores 1742, a -13.8% delta. That single-core margin, while still a win for Intel, is far smaller than the multicore deltas, which suggests that AMD's Zen 3+ architecture remains competitive in lightly threaded workloads.

PassMark tests reinforce the multicore dominance. In data compression, Intel scores 665554 against AMD's 168692, a -74.7% delta. Data encryption shows 48246 versus 10718, a -77.8% delta. Extended instructions deliver 54333 versus 11219, a -79.4% delta. Floating point math shows 189629 versus 27800, an -85.3% delta, one of the wider gaps in the set. Integer math is comparatively closer at -64.5%, with Intel at 143242 and AMD at 50800. Multithread performance shows 58594 versus 14520, a -75.2% delta. Physics tests put Intel at 3731 and AMD at 821, a -78% delta. Random string sorting yields 79752 versus 17669, -77.8%. Even the single-thread PassMark tests, which are the closest category, show Intel at 4928 against AMD's 2740, a -44.4% delta.

The average benchmark score tells the same story. The AMD Ryzen 5 7533HS records an average score of 19364, while the Intel Core Ultra 7 265K records 70879. The AMD part sits at the 73rd percentile of all CPUs in the database, while the Intel part sits at the 94th percentile. The nearest rivals for the AMD chip are the Intel Core Ultra 5 226V at 19368 (0% delta), the Intel Core i5-1345U at 19411 (-0.2%), the Intel Core i7-8700K at 19238 (0.7%), and the Intel Core i7-10700F at 19499 (-0.7%). For the Intel Core Ultra 7 265K, the nearest rivals are the Intel Xeon 6511P at 71051 (-0.2%), the Intel Xeon Platinum 8270 at 71370 (-0.7%), the Intel Core i7-14700KF at 70163 (1%), and the AMD Ryzen 7 9700F at 69996 (1.3%). These rival lists show that the AMD chip competes with mid-range laptop parts and older desktop chips, while the Intel chip trades blows with server-class Xeons and high-end desktop parts.

The Verdict

The data does not present a balanced contest. The Intel Core Ultra 7 265K is faster in every recorded benchmark, and in most tests the margin is massive. The AMD Ryzen 5 7533HS holds its ground best in Cinebench R23 singlecore, where it trails by only 13.8%, but that is the sole bright spot. The Intel part's 20 cores and 20 threads against AMD's 6 cores and 12 threads explain much of the multicore gap, but even single-thread tests favor Intel by 13.8% to 75.3%, depending on the benchmark.

The AMD chip is a 35 W mobile processor with a 4.40 GHz boost clock, while the Intel chip is a 125 W desktop processor with a 5.50 GHz boost clock. Those are different product classes. The Ryzen 5 7533HS belongs to the 7000 series, targets mobile workloads, and uses AMD Socket FP7. The Core Ultra 7 265K targets desktops, uses Intel Socket 1851, and has an unlocked multiplier. The benchmark results reflect that positioning. No recorded test shows the AMD part winning, and the average score gap is roughly a factor of 3.7.

For users constrained to a 35 W mobile platform, the Ryzen 5 7533HS delivers competitive single-core performance relative to its class, as shown by the modest R23 singlecore deficit. For users who need maximum throughput in multi-threaded applications, the Intel Core Ultra 7 265K is the clear choice. The launch MSRP for the Intel part is $394. The AMD part has no recorded launch MSRP in the database.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7533HS uses Zen 3+ architecture with the codename Rembrandt-R, built on a 6 nm TSMC process. 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 265K uses Arrow Lake architecture with the codename Arrow Lake-S, built on a 3 nm TSMC process. It has 20 cores and 20 threads, with a base clock of 3.90 GHz and a boost clock of 5.50 GHz. The Intel part has no hyper-threading, hence 20 threads from 20 cores, while the AMD part uses simultaneous multithreading to reach 12 threads from 6 cores.

Cache configurations differ sharply. The AMD part has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel part has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The die sizes reflect the complexity difference: AMD measures 208 mm², while Intel measures 243 mm². The Intel part also lists 17,800 million transistors, while the AMD part has no transistor count recorded in the database.

Memory support is DDR5 for both, and both use dual-channel memory buses. The recorded memory bandwidth favors Intel at 102.4 GB/s versus AMD's 76.8 GB/s. The AMD part does not support ECC memory, while the Intel part does. PCIe generation differs as well: AMD provides Gen 4 with 20 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only).

Integrated graphics also differ. The AMD part uses Radeon 660M, while the Intel part uses Arc Xe-LPG Graphics 64EU. Both are desktop or mobile integrated solutions, but the database does not include graphics benchmarks for either part. The AMD part is not multiplier-unlocked, while the Intel part is. The AMD part's production status is active, and so is the Intel part's. The AMD release date is 2024-08-31, while the Intel release date is 2024-10-23.

Where Each One Wins

The Intel Core Ultra 7 265K wins every recorded category, but the scale of those wins varies. The largest deltas are in PassMark find prime numbers (-90.2%), floating point math (-85.3%), and extended instructions (-79.4%). These are heavily parallel or instruction-intensive workloads, and the Intel part's 20 cores plus higher memory bandwidth (102.4 GB/s versus 76.8 GB/s) drive the advantage. The smallest Intel win is in Cinebench R23 singlecore, at -13.8%, which means the AMD part is relatively strongest in lightly threaded rendering tasks. The PassMark single-thread tests show a -44.4% delta, so the AMD part is closer there than in most multicore tests, but still clearly behind.

The AMD Ryzen 5 7533HS has no recorded benchmark wins, so its case rests on platform characteristics rather than measured performance. It draws 35 W of TDP against Intel's 125 W, which suits thin-and-light mobile designs. It uses AMD Socket FP7, while the Intel part uses Intel Socket 1851, so the two are not interchangeable in any system. The AMD part is smaller in die size (208 mm² versus 243 mm²) and uses the older 6 nm process node. Its integrated graphics, Radeon 660M, may serve basic display tasks, and its 16 MB of L3 cache is smaller than Intel's 30 MB.

For desktop builders with power headroom and a need for throughput, the Intel Core Ultra 7 265K is the only choice according to the data. For mobile users who need a 35 W part, the Ryzen 5 7533HS exists in a different product class entirely, and its single-core Cinebench R23 result suggests it handles lightly threaded tasks with reasonable competence relative to the desktop flagship. The database does not record any scenario where the AMD part outperforms the Intel part, so any use-case split must acknowledge that the Intel chip dominates on raw performance while the AMD chip offers a lower-power mobile form factor.
