AMD Ryzen 7 5825U vs Intel Core i5-13400F Comparison

The AMD Ryzen 7 5825U and Intel Core i5-13400F represent two fundamentally different computing philosophies: a 15-watt mobile processor designed for battery-powered efficiency against a 65-watt desktop chip built for sustained performance. The benchmark data is unambiguous—the Intel Core i5-13400F wins all 17 head-to-head comparisons, often by substantial margins, making it the clear performance leader. However, the Ryzen 7 5825U’s integrated graphics, lower power envelope, and mobile socket position it as the practical choice for thin-and-light laptops, while the Intel chip requires a discrete GPU and desktop platform.

Architecture Differences

The AMD Ryzen 7 5825U is built on TSMC’s 7 nm process, using the Zen 3 architecture under the Barcelo codename. It packs 10,700 million transistors into a 180 mm² die. The Intel Core i5-13400F uses Intel’s 10 nm process with the Raptor Lake architecture, on a larger 215 mm² die with no transistor count listed. These process differences explain the power disparity: AMD’s chip draws 15 watts TDP versus Intel’s 65 watts.

The Ryzen 7 5825U uses a monolithic design with 8 full Zen 3 cores. The Intel Core i5-13400F uses a hybrid architecture, combining performance and efficiency cores to reach 10 total cores. Cache configurations differ significantly: AMD provides 64 KB L1 and 512 KB L2 per core, with 16 MB shared L3. Intel provides 80 KB L1 and 1.25 MB L2 per core, with 20 MB shared L3. The larger per-core L2 cache on Intel likely contributes to its single-thread advantages.

Platform support diverges sharply. The AMD chip uses the FP6 socket with PCIe Gen 3 (16 CPU lanes) and dual-channel DDR4 memory with 51.2 GB/s bandwidth, plus ECC memory support. Intel uses Socket 1700 with PCIe Gen 5 (16 CPU lanes) and dual-channel DDR4 or DDR5 memory, but no ECC support. Intel’s PCIe Gen 5 provides double the bandwidth of AMD’s Gen 3 for future expansion. AMD includes Radeon Vega 8 integrated graphics; Intel has none, requiring a separate GPU.

Both processors are currently in active production. The AMD Ryzen 7 5825U was released on January 5, 2022, targeting the mobile market. The Intel Core i5-13400F launched on January 3, 2023, for desktop systems. Neither has an unlocked multiplier, so overclocking is not officially supported on either platform.

Head-to-Head Benchmarks

The Intel Core i5-13400F dominates every single benchmark in the comparison, but the magnitude varies widely by workload. The largest gap appears in Cinebench R23 multi-core, where Intel scores 22,604 versus AMD’s 10,152, a 55.1% difference. This suggests Intel’s 10-core hybrid design scales much better under sustained multi-threaded rendering loads than AMD’s 8-core Zen 3 chip.

Single-core performance shows a similar but slightly smaller gap. Cinebench R23 single-core gives Intel a 54.5% lead (3,191 versus 1,452). The older Cinebench R15 single-core test shows a 27.7% difference (321 versus 232), indicating the gap widens with newer, more demanding benchmarks. Geekbench single-core is closer at 18.9% (1,996 versus 1,618), while PassMark single-thread shows a 16% difference (3,634 versus 3,053).

Integer-heavy workloads show the smallest deltas. PassMark integer math has Intel ahead by only 9.2% (79,942 versus 72,577). This is the closest result in the entire comparison, suggesting AMD’s Zen 3 architecture remains competitive for basic arithmetic operations. In contrast, PassMark physics shows a 46.1% Intel advantage (1,437 versus 774), indicating a major gap in simulated physics calculations.

Memory and encryption tasks follow the general trend. PassMark data compression is 28.7% faster on Intel (311,364 versus 221,938), data encryption is 15.2% faster (16,608 versus 14,088), and random string sorting is 26.6% faster (32,076 versus 23,539). Extended instructions show a 27.5% Intel lead (19,847 versus 14,394). Floating-point math is 36.4% faster on Intel (60,539 versus 38,482), while prime number finding is 42.2% faster (83 versus 48). PassMark multi-thread overall is 27.6% faster (25,032 versus 18,131).

Specification Differences

The core count differs: AMD has 8 cores, Intel has 10. Both have 16 threads. Base clocks are 2.00 GHz for AMD and 2.50 GHz for Intel; boost clocks are 4.50 GHz and 4.60 GHz respectively. TDP is the most striking difference: 15 watts for AMD versus 65 watts for Intel.

The memory support differs completely. AMD supports DDR4 only, with 51.2 GB/s bandwidth. Intel supports both DDR4 and DDR5, with no bandwidth figure listed. ECC memory is supported on AMD but not on Intel. PCIe generations differ: AMD provides Gen 3 with 16 lanes, Intel provides Gen 5 with 16 lanes.

Integrated graphics are present on AMD (Radeon Vega 8) but absent on Intel. The AMD chip uses Socket FP6 for mobile systems; Intel uses Socket 1700 for desktops. Process nodes differ: 7 nm TSMC versus 10 nm Intel. Die size is 180 mm² for AMD and 215 mm² for Intel. AMD lists 10,700 million transistors; Intel lists none. Cache structures differ: AMD has 64 KB L1 and 512 KB L2 per core with 16 MB shared L3; Intel has 80 KB L1 and 1.25 MB L2 per core with 20 MB shared L3.

The Intel Core i5-13400F has a launch MSRP of $196. The AMD Ryzen 7 5825U has no launch MSRP listed, as it is a mobile OEM part. Release dates are close: January 5, 2022 for AMD and January 3, 2023 for Intel. Both are in active production and neither has an unlocked multiplier.

Where Each One Wins

The Intel Core i5-13400F wins every benchmark category, but the use case determines whether that matters. For desktop users building a performance system, Intel is the only choice among these two. Its 55.1% lead in Cinebench R23 multi-core makes it ideal for video rendering, 3D modeling, and other heavily threaded creative workloads. The 46.1% advantage in PassMark physics suits simulation and scientific computing. The 42.2% lead in prime number finding benefits cryptography and mathematical research. The 36.4% floating-point advantage helps with financial modeling and engineering simulations.

The AMD Ryzen 7 5825U wins in efficiency and platform integration. Its 15-watt TDP is designed for laptops, where sustained battery life and low heat generation are priorities. The integrated Radeon Vega 8 graphics eliminates the need for a separate GPU, reducing system cost and power draw for basic productivity tasks. The mobile FP6 socket places it in thin-and-light notebooks, while Intel’s desktop Socket 1700 requires a full ATX or micro-ATX build. AMD’s ECC memory support also makes it suitable for entry-level workstations where data integrity is critical, a feature Intel lacks.

For users who need a single system for office work, web browsing, and light content consumption, the Ryzen 7 5825U’s integrated graphics and low power draw make it the practical choice. For anyone building a dedicated desktop with a discrete GPU, the Intel Core i5-13400F’s raw performance across every benchmark metric is unmatched by the AMD part.

The Verdict

The data is clear: the Intel Core i5-13400F is the superior processor in every measured benchmark, with wins across all 17 head-to-head comparisons. The margins range from 9.2% in PassMark integer math to 55.1% in Cinebench R23 multi-core. Its 10-core hybrid architecture, higher clocks, and larger caches translate into decisive advantages in both single-threaded and multi-threaded workloads. For desktop builders who already have a GPU, the Intel chip is the definitive choice.

The AMD Ryzen 7 5825U is not without merit, but its strengths lie outside raw benchmark scores. Its 15-watt TDP, integrated Radeon Vega 8 graphics, and mobile socket make it the only option for laptop users. The ECC memory support and lower power draw give it a niche in compact, always-on systems where efficiency trumps performance. The average benchmark scores are nearly identical (25,446 versus 25,292), but this is misleading; the Intel chip wins every head-to-head test by significant margins.

Choose the Intel Core i5-13400F if you are building a desktop with a discrete GPU and prioritize maximum performance in rendering, physics, encryption, and math workloads. Choose the AMD Ryzen 7 5825U if you need a mobile processor with integrated graphics, low power consumption, and ECC memory support, accepting that it will be significantly slower in every computational task. The verdict is not about which is better overall, but which fits the intended platform—and for pure performance, Intel wins without exception.
