Head-to-Head Benchmarks

The recorded data shows a clear split between these two processors. The Intel Core i7-13800H wins 10 of the 13 shared benchmark comparisons, while the AMD Ryzen 7 3700X takes 3 victories. The largest margin for Intel comes in floating point math, where the i7-13800H scores 66,579 against the Ryzen's 39,005, a 70.7% advantage. Physics performance follows a similar pattern, with the Intel part scoring 1,924 versus 1,181, a 62.9% lead. Integer math also heavily favors Intel, with a score of 92,589 compared to 66,399, a 39.4% difference.

Single-thread performance is another decisive area. The i7-13800H records 3,543 in PassMark single-thread tests, which is 33.4% ahead of the Ryzen 7 3700X's 2,656. Cinebench R15 single-core confirms this trend, with Intel scoring 261 and AMD scoring 204, a 27.9% gap. The Intel processor also leads in multithreaded PassMark performance, scoring 26,545 against 22,458, an 18.2% advantage. Prime number finding shows a 16.2% lead for Intel, with scores of 115 and 99 respectively. Random string sorting is closer, with Intel ahead by 3.3%, scoring 33,188 versus 32,131. Data compression is nearly identical, with Intel at 299,179 and AMD at 296,379, a mere 0.9% difference.

The AMD Ryzen 7 3700X's wins are concentrated in specific workloads. Cinebench R15 multicore is its biggest victory, scoring 2,092 against Intel's 1,850, an 11.6% lead. Data encryption favors AMD by 6.2%, with scores of 18,900 versus 17,726. Extended instructions also go to AMD, with 19,241 against 18,011, a 6.4% difference. These three wins show that the older Zen 2 architecture still holds ground in certain legacy or specialized tasks, but the overall benchmark picture is dominated by the newer Intel mobile chip.

Where Each One Wins

The Intel Core i7-13800H is the clear choice for compute-heavy single-threaded workloads. Its 33.4% lead in PassMark single-thread and 27.9% lead in Cinebench R15 single-core means applications that rely on one or few cores will see substantial benefits. This includes everyday responsiveness, lightweight productivity tasks, and games that scale poorly across many cores. The 70.7% advantage in floating point math and 39.4% lead in integer math indicate strong performance in scientific computing, financial modeling, and video encoding where these operations are common. The 62.9% physics advantage suggests better performance in physics simulation, which often appears in modern game engines and engineering software. Multithreaded work also favors Intel, with an 18.2% lead in PassMark multithread, making it suitable for rendering, compilation, and heavy content creation.

The AMD Ryzen 7 3700X wins in three specific areas. Its 11.6% lead in Cinebench R15 multicore is notable because this benchmark is often used as a proxy for older multithreaded workloads. The 6.2% advantage in data encryption suggests the AMD chip handles cryptographic tasks more efficiently, which could matter for security software, VPNs, and encrypted storage. The 6.4% lead in extended instructions points to better performance with SIMD-heavy codebases that use AVX2 or similar instruction sets. For users running legacy software that relies on these specific workloads, the Ryzen 7 3700X remains competitive.

Architecture Differences

These processors represent different design philosophies and manufacturing approaches. The Intel Core i7-13800H uses Raptor Lake architecture on a 10 nm process node, fabricated by Intel itself. It integrates 14 cores and 20 threads, relying on a hybrid design that mixes performance and efficiency cores. The die size is 257 mm². The AMD Ryzen 7 3700X uses Zen 2 architecture on a 7 nm process node from TSMC, with 3,800 million transistors on a 74 mm² die. It has 8 cores and 16 threads, a traditional homogeneous core layout. The smaller die size for AMD is partly due to the chiplet design typical of Zen 2, but the database does not detail the chiplet layout.

Cache configurations differ significantly. Intel provides 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 cache. The larger L3 on AMD helps with cache-sensitive workloads, but the per-core L2 advantage on Intel (2 MB versus 512 KB) supports its single-threaded strength. Memory support also diverges: the Intel chip supports both DDR4 and DDR5, while the AMD chip is limited to DDR4. Both use dual-channel memory buses. AMD lists a memory bandwidth of 51.2 GB/s, while Intel does not specify a bandwidth figure in the database.

PCIe connectivity differs. Intel supports PCIe Gen 5 with 8 CPU lanes, while AMD supports PCIe Gen 4 with 24 CPU lanes. This means the AMD platform offers more total lanes, but Intel's lanes are a newer generation with higher per-lane bandwidth. Integrated graphics are present on the Intel chip (Iris Xe Graphics 96EU), while the AMD Ryzen 7 3700X has none, requiring a discrete GPU for display output. The Intel processor uses the Intel BGA 1744 socket, indicating a mobile form factor, while the AMD chip uses the desktop AM4 socket. The Intel part is unlocked? No, the multiplier is locked. The AMD part has an unlocked multiplier, allowing overclocking. The Intel chip has a TDP of 45 watts, while the AMD chip is rated at 65 watts. The Intel chip was released in January 2023, while the AMD chip launched in July 2019.

The Verdict

The database points to the Intel Core i7-13800H for most users. It wins 10 of 13 head-to-head benchmarks, with decisive margins in floating point math, physics, integer math, and single-thread performance. Its 14 cores and 20 threads provide a thread count advantage over the Ryzen's 8 cores and 16 threads, and its support for both DDR4 and DDR5 gives more memory flexibility. The integrated Iris Xe Graphics also eliminates the need for a discrete GPU in basic display scenarios. The Intel chip's 84th percentile ranking among all CPUs matches the Ryzen's percentile, but the average benchmark score is higher for Intel (34,988 versus 34,260). The i7-13800H also has a higher boost clock (5.20 GHz versus 4.40 GHz) and a newer release date.

The AMD Ryzen 7 3700X is the choice for a specific set of workloads. It wins Cinebench R15 multicore, data encryption, and extended instructions. Its larger L3 cache (32 MB versus 24 MB) and higher base clock (3.60 GHz versus 2.50 GHz) may help in certain cache-sensitive or latency-sensitive tasks. The unlocked multiplier allows overclocking, which is not available on the Intel chip. The AMD part also has more PCIe lanes (24 versus 8) and a lower launch MSRP ($329 versus $457). For users who prioritize older multithreaded benchmarks, cryptographic workloads, or SIMD-heavy code, the Ryzen 7 3700X remains viable. However, the overall benchmark record favors the Intel Core i7-13800H for general-purpose and modern application performance.
