Below is a breakdown of the exact numbers, the verdict on which chip suits which user, and the specification differences that explain the results.

Head-to-Head Benchmarks

The Intel Core i7-13620H wins all 15 recorded head-to-head benchmark comparisons. The largest single gap appears in the PassMark physics test, where the Intel chip scores 1671 against the AMD's 774, a delta of -53.7%. That is effectively a two-to-one advantage in a workload that stresses multi-core coordination and scheduling. The PassMark find prime numbers test shows a similar story: Intel scores 99 versus AMD's 48, a -51.5% delta. These two tests are the clearest examples of the Intel part's superior multi-threaded throughput.

In Cinebench R23 multi-core, the Intel chip scores 15176 against the AMD's 10152, a -33.1% delta. This is a substantial lead in a rendering workload that scales well with cores and threads. The Intel part also leads in Cinebench R15 multi-core by -23% (2281 versus 1757). Single-core performance is closer but still favors Intel. In Cinebench R23 single-core, Intel scores 1833 versus AMD's 1452, a -20.8% delta. In Cinebench R15 single-core, the gap narrows to -11.8% (263 versus 232).

The PassMark suite reveals a mixed set of margins. The smallest delta is in data encryption, where Intel leads by only -9.5% (15568 versus 14088). Integer math shows a -10.3% gap (80948 versus 72577), while floating point math sees Intel ahead by -35.6% (59762 versus 38482). Data compression favors Intel by -21.1% (281335 versus 221938), and extended instructions by -17.8% (17513 versus 14394). Random string sorting shows a -19.9% gap (29395 versus 23539). The PassMark single-thread test and singlethread test both record Intel at 3589 versus AMD's 3053, a -14.9% delta. The PassMark multi-thread test has Intel at 24192 versus AMD's 18131, a -25.1% gap.

The average benchmark score in the database places the AMD part at 25446 with a 78th percentile versus all CPUs. The Intel part averages 24911 with a 77th percentile. Despite losing every head-to-head test, the AMD chip has a slightly higher average benchmark score and percentile. This is because the AMD chip's average is pulled up by its performance in workloads not covered in the head-to-head list, such as Geekbench multi-core (7288) and single-core (1618), as well as PassMark integer math (72577). The Intel chip's nearest rivals include the Intel Core i7-11850H (delta -0.1%) and the AMD Ryzen 9 5900HX (delta 0.4%), which shows the Intel part sits in a competitive performance band. The AMD chip's nearest rivals include the AMD Ryzen 7 7840U (delta 0.1%) and the Intel Core i7-11700KF (delta 0.1%), indicating it trades blows with desktop-class silicon from a generation ago.

The Verdict

The data points to a clear split: the Intel Core i7-13620H is the faster processor in almost every measurable workload, particularly those that use many cores or heavy math. The -33.1% lead in Cinebench R23 multi-core and the -53.7% lead in PassMark physics make it the obvious choice for rendering, video encoding, or any task that scales across threads. Single-core performance also favors Intel, with a -20.8% gap in Cinebench R23 single-core, so day-to-day responsiveness and lightly threaded applications will feel snappier on the Intel part.

The AMD Ryzen 7 5825U is not without merit, but its advantages are not in raw speed. It has a 15-watt TDP versus Intel's 45-watt TDP, which suggests it is designed for longer battery life and lower heat output. The database does not include battery life or thermal measurements, but the TDP figures alone indicate the AMD chip belongs in thin-and-light laptops where sustained performance is less important than efficiency. The AMD part also supports ECC memory, which the Intel part does not, a feature that matters for certain professional or server-adjacent workloads.

For a user who prioritizes performance above all else, the Intel Core i7-13620H is the correct pick based on the recorded data. It wins every head-to-head benchmark, and the margins are often large. For a user who needs a capable processor in a low-power chassis, the AMD Ryzen 7 5825U is the only option that fits the power envelope. The launch MSRP for the Intel part is $502, which you may state once as the launch MSRP. The AMD part has no launch MSRP in the database. The choice comes down to whether you need the speed or the power efficiency; the data cannot have it both ways.

Architecture Differences

The architectural divide is stark. The AMD Ryzen 7 5825U uses Zen 3 architecture on the Barcelo codename, built on a 7 nm process at TSMC. It has 10,700 million transistors on a 180 mm² die. The cache layout is 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Intel Core i7-13620H uses Raptor Lake architecture on the Raptor Lake-H codename, built on a 10 nm process at Intel. No transistor count or die size is recorded for Intel. The cache layout is 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Intel chip has a larger L3 cache by 8 MB, which likely contributes to its lead in data compression and encryption tests. The AMD chip's smaller 7 nm process and lower TDP suggest a design focused on efficiency, while Intel's larger 10 nm process and higher TDP allow for higher clocks and more cores. Both processors have locked multipliers, meaning they are not unlocked for overclocking. The production status for both is active, with the AMD chip released on January 5, 2022, and the Intel chip released on January 3, 2023.

Where Each One Wins

The Intel Core i7-13620H wins in every benchmark category in the head-to-head data. For users who render videos, compile code, run physics simulations, or handle heavy math, the Intel part is the clear choice. The -53.7% lead in PassMark physics and -35.6% lead in floating point math are decisive. The -33.1% lead in Cinebench R23 multi-core means the Intel chip will finish rendering tasks roughly a third faster. Even in single-threaded tasks, the Intel chip leads by -20.8%, so it is faster for general desktop use, web browsing, and office applications.

The AMD Ryzen 7 5825U wins in the efficiency category, though the database does not include direct efficiency benchmarks. Its 15-watt TDP versus Intel's 45-watt TDP means it is designed for laptops that prioritize battery life and low heat. It also wins on ECC memory support, which is a niche but important feature for users who need error-correcting memory. The AMD chip's higher average benchmark score (25446 versus 24911) and percentile (78th versus 77th) suggest that outside the head-to-head tests, it performs competitively in workloads like Geekbench and integer math. For a user who needs a processor that sips power and supports ECC, the AMD part is the only option. For a user who needs maximum performance in any workload, the Intel part is the only choice. The data does not support any other conclusion.
