Architecture Differences

The Intel Core i5-12450H is built on Alder Lake architecture, specifically the Alder Lake-H variant, using a 10 nm process node from Intel's own foundry. It uses the Intel BGA 1744 socket. The AMD Ryzen 3 7335U uses Zen 3+ architecture, codenamed Rembrandt-R, fabricated on a 6 nm process by TSMC, and fits the AMD Socket FP7.

The core configurations differ substantially. The Intel part has 8 cores and 12 threads, while the AMD part has 4 cores and 8 threads. Cache layouts also diverge. The Intel chip carries 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The AMD chip has 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3.

The die sizes are close, with Intel at 217 mm² and AMD at 208 mm². The integrated graphics differ as well: Intel uses UHD Graphics, while AMD uses Radeon 660M. Memory support shows a clear split. The Intel processor supports both DDR4 and DDR5, whereas the AMD processor supports only DDR5. ECC memory is supported on the AMD chip but not on the Intel chip.

The process node advantage leans toward AMD, as 6 nm is smaller than 10 nm, and the foundry is TSMC rather than Intel. The Intel part has a higher TDP of 45 W compared to the AMD part's 28 W, which aligns with its higher core count and generally higher benchmark scores. Both chips have locked multipliers, so neither supports overclocking.

Head-to-Head Benchmarks

The Intel Core i5-12450H dominates the head-to-head comparison, winning 16 of 17 recorded tests. The margins are often large. In Cinebench R15 single-core, Intel scores 238 versus AMD's 152, a 56.6% advantage. That is the biggest single-thread gap in the dataset. In Cinebench R20 single-core, Intel leads 800 to 634, a 26.2% edge. Cinebench R23 single-core shows a narrower margin, with Intel at 1661 and AMD at 1511, a 9.9% lead.

Multi-threaded results are more nuanced. Intel wins Cinebench R15 multicore with 1350 versus 1078, a 25.2% margin. In Cinebench R20 multicore, Intel scores 5671 against AMD's 4495, a 26.2% lead. However, the AMD Ryzen 3 7335U takes a decisive win in Cinebench R23 multicore, scoring 10703 against Intel's 8822.5, a 17.6% advantage. This is the only benchmark where AMD comes out ahead.

Passmark results strongly favor Intel. The largest margin is in floating point math, where Intel scores 40568 and AMD scores 24298, a 67% difference. Integer math shows Intel at 54782 versus 42493, a 28.9% lead. Data compression favors Intel at 195132 versus 146309, a 33.4% margin. Extended instructions go to Intel at 11992 versus 10314, a 16.3% edge. Data encryption is closer, with Intel at 10832 and AMD at 9335, a 16% difference. Physics testing gives Intel 883 against AMD's 647, a 36.5% lead. Random string sorting shows Intel at 20838 against AMD's 15361, a 35.7% margin. Prime number finding favors Intel at 46 versus 36, a 27.8% lead. Passmark multithread scores show Intel at 16265 and AMD at 12592, a 29.2% advantage. Passmark single-thread gives Intel 3306 versus 3053, an 8.3% lead.

The overall average benchmark scores reflect this: Intel has an average of 17239, while AMD has 16827. The Intel chip sits at the 71st percentile of all CPUs, and the AMD chip at the 70th percentile.

Specification Differences

The Verdict

The benchmark data paints a clear picture for most workloads. The Intel Core i5-12450H is the stronger processor in the majority of tests, winning 16 out of 17 head-to-head comparisons. Its advantages are especially pronounced in single-thread performance, where it leads by as much as 56.6% in Cinebench R15 single-core. The Intel chip also wins in most multi-thread tests, including Cinebench R15 and R20 multicore, as well as every Passmark multithread and math test.

The AMD Ryzen 3 7335U has one notable victory: Cinebench R23 multicore, where it scores 10703 against Intel's 8822.5, a 17.6% lead. This result is unusual given AMD's lower core count, but it is a real data point. However, it is the only test where AMD comes out ahead. The AMD chip also has a lower TDP of 28 W versus 45 W, which suggests less power draw, though the database does not include any thermal or power measurements beyond TDP.

For a buyer looking at raw performance across the recorded benchmarks, the Intel Core i5-12450H is the safer choice. It wins more tests, wins by larger margins, and has a higher average benchmark score at 17239 versus 16827. The AMD chip is not far behind in overall percentile, sitting at 70 versus Intel's 71, but the per-test results show a consistent Intel advantage.

The recommendation depends on the specific use case. For single-threaded applications, such as many older games or lightly threaded productivity tools, the Intel chip is clearly superior. For heavily threaded workloads like video encoding or 3D rendering, the Intel chip wins in most tests, though the AMD chip's Cinebench R23 multicore result shows it can win in specific rendering workloads. The AMD chip's lower TDP may matter for thin-and-light laptops, but the database does not provide power or thermal measurements to quantify that benefit.

Where Each One Wins

The Intel Core i5-12450H wins in the following categories based on the recorded data: single-thread performance across all Cinebench and Passmark tests, multi-thread performance in Cinebench R15 and R20, data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, Passmark multithread, physics, and random string sorting. It also has more cores and threads, larger cache at all levels, and supports both DDR4 and DDR5 memory.

The AMD Ryzen 3 7335U wins in exactly one benchmark: Cinebench R23 multicore. It also has a smaller process node at 6 nm, a lower TDP at 28 W, ECC memory support, a higher base clock at 3.00 GHz, and a recorded memory bandwidth of 76.8 GB/s. The AMD chip uses Radeon 660M graphics, while Intel uses UHD Graphics, though the database does not include graphics benchmarks.

For users prioritizing single-thread responsiveness, data encryption, floating point math, or integer math, the Intel Core i5-12450H is the clear choice. For users running workloads similar to Cinebench R23 multicore, which may indicate certain rendering or simulation tasks, the AMD Ryzen 3 7335U shows a specific advantage. For users who need ECC memory or prefer a 6 nm process, the AMD chip offers those features, but the performance data shows the Intel chip wins the vast majority of comparisons.
