Architecture Differences

The architectural split is fundamental. The AMD Ryzen 7 5800H is built on TSMC’s 7 nm process using AMD’s Zen 3 architecture, codenamed Cezanne. It features 8 cores and 16 threads, with a base clock of 3.20 GHz and a boost clock of 4.40 GHz. The cache layout is 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. This is a mobile processor on AMD Socket FP6, designed for laptops, with integrated Radeon Vega 8 graphics.

The Intel Core i5-13400 is a desktop part on Intel Socket 1700, built on Intel’s 10 nm process using the Raptor Lake architecture, codenamed Raptor Lake-S. It has 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. The cache is larger per core: 80 KB L1, 1.25 MB L2, and 20 MB shared L3. The die size is also larger at 215 mm² versus AMD’s 180 mm², and Intel’s transistor count is not listed in the database.

Memory and I/O differ sharply. The AMD chip is limited to DDR4 with dual-channel support and a memory bandwidth of 68.3 GB/s. The Intel chip supports both DDR4 and DDR5, also dual-channel, but its memory bandwidth is not recorded. PCIe support shows Intel with Gen 5 (16 lanes, CPU only) versus AMD’s Gen 3. Neither processor supports ECC memory, and both have locked multipliers. The integrated graphics are distinct: Radeon Vega 8 for AMD, UHD Graphics 730 for Intel.

Head-to-Head Benchmarks

The head-to-head data records 23 test comparisons, and the Intel Core i5-13400 wins 21 of them. The scale of the Intel advantage varies widely by workload. In Geekbench multicore, the Intel part scores 12289 versus 8230, a 33% lead, which is the largest delta in the entire set. Cinebench R23 multicore shows a 24.2% gap (15953 vs 12091.5), and PassMark floating point math is 24.3% ahead (58786 vs 44479). These are substantial margins for multi-threaded content creation and compute-heavy tasks.

Single-threaded performance also favors Intel consistently. In Cinebench R23 single-core, Intel leads by 20.7% (1786 vs 1416), and in Geekbench single-core by 21% (2112 vs 1669). 3DMark single-thread shows a 14.6% gap (959 vs 819). The Intel chip’s higher boost clock of 4.60 GHz versus 4.40 GHz likely contributes, though the architecture differences are more significant.

The AMD Ryzen 7 5800H’s two wins are narrow but notable. In PassMark data encryption, it scores 16962 against Intel’s 15880, a 6.8% advantage. In PassMark integer math, it scores 80786 against 77721, a 3.9% lead. These are specialized workloads where the Zen 3 core design appears to have an edge, but they are isolated wins in an otherwise Intel-dominated field.

The smallest Intel margins are in PassMark extended instructions (5% ahead, 19161 vs 18203) and PassMark random string sorting (8.8% ahead, 30851 vs 28144). For lighter parallel tasks, the gap narrows: 3DMark 8 threads shows Intel only 8.7% ahead (5592 vs 5105), and 3DMark 4 threads is 11.8% ahead (3461 vs 3053). These results suggest that in short, bursty workloads, the AMD chip remains competitive despite its older architecture.

Specification Differences

The core count differs: 8 cores for AMD versus 10 cores for Intel, though both have 16 threads. Base clocks differ significantly, with AMD at 3.20 GHz and Intel at 2.50 GHz, but boost clocks reverse the order: AMD at 4.40 GHz and Intel at 4.60 GHz. TDP is 45 watts for AMD and 65 watts for Intel, reflecting the mobile versus desktop market segments.

Cache sizes diverge across all levels. AMD has 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. Intel has 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. The process node is 7 nm (TSMC) for AMD and 10 nm (Intel) for Intel. Die size is 180 mm² for AMD and 215 mm² for Intel; transistor count is only listed for AMD at 10,700 million.

Memory support is a clear split: AMD supports only DDR4, while Intel supports DDR4 and DDR5. Memory bandwidth is recorded only for AMD at 68.3 GB/s. PCIe generation differs: AMD has Gen 3, Intel has Gen 5 with 16 lanes (CPU only). Integrated graphics are Radeon Vega 8 for AMD and UHD Graphics 730 for Intel. Sockets are AMD Socket FP6 versus Intel Socket 1700. Release dates are January 11, 2021 for AMD and January 3, 2023 for Intel. The Intel part has a launch MSRP of $221; the AMD part has no recorded launch MSRP.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-13400 is the faster processor in almost every measured scenario. With a 21 to 2 win record in head-to-head tests, it dominates multi-threaded and single-threaded workloads alike. The largest gaps, such as 33% in Geekbench multicore and 24.2% in Cinebench R23 multicore, show that the Intel part is substantially ahead for rendering, compiling, and heavy multitasking. Its higher boost clock and larger cache likely explain the pervasive single-threaded lead, which ranges from 10.9% to 21% depending on the test.

The AMD Ryzen 7 5800H should only be chosen when its specific strengths matter. It wins in data encryption and integer math, and it consumes less power with a 45 watt TDP versus Intel’s 65 watts. It is also a mobile processor, designed for laptops, whereas the Intel part is a desktop chip. For users constrained to a laptop platform, the 5800H is the only option between the two, but for desktop builders, the Intel Core i5-13400 is the clear choice based on performance data.

Neither processor shows a meaningful overall percentile difference, with both sitting at the 76th percentile among all CPUs. The average benchmark scores are close in the database, with Intel at 24280 and AMD at 23277, but the head-to-head deltas reveal where that small average gap comes from: Intel’s wins are often large, while AMD’s wins are small. The verdict is straightforward: pick Intel for raw performance, pick AMD for power efficiency and specific encryption or integer math tasks.

Where Each One Wins

The Intel Core i5-13400 wins in nearly every category that matters for general use and productivity. It leads in all 3DMark tests, from 2 threads (1883 vs 1595) to 16 threads (7315 vs 6143), indicating stronger scaling across thread counts. It wins every Cinebench test, with R15 multicore at 2358 vs 2005 and R23 multicore at 15953 vs 12091.5. Geekbench multicore and single-core both go to Intel by large margins (12289 vs 8230 and 2112 vs 1669). PassMark multithread (23719 vs 20789), physics (1244 vs 830), floating point math (58786 vs 44479), and find prime numbers (74 vs 49) all favor Intel. For any workload involving video rendering, software compilation, or heavy multitasking, the Intel part is the superior choice.

The AMD Ryzen 7 5800H wins in two specific PassMark tests: data encryption (16962 vs 15880) and integer math (80786 vs 77721). These are narrow but consistent wins, suggesting an architectural advantage for cryptographic operations and integer-heavy calculations. The AMD chip also has a lower TDP at 45 watts, making it the better fit for thermally constrained laptops or systems where power draw is a priority. Its mobile design means it can operate in platforms where the desktop Intel part cannot be installed. For users who need a laptop CPU with acceptable performance and lower power consumption, the 5800H is the practical pick, but for desktop performance, the Intel Core i5-13400 is the definitive winner across the recorded benchmarks.
