Architecture Differences

The Intel Core i7-13620H is based on Raptor Lake architecture, specifically Raptor Lake-H, and is fabricated on Intel's 10 nm process. It uses the Intel BGA 1744 socket. The AMD Ryzen 7 6800H employs Zen 3+ architecture under the Rembrandt codename, built on TSMC's 6 nm process with a die size of 208 mm², and uses the AMD Socket FP7.

Core configuration differs significantly: Intel provides 10 cores with 16 threads, while AMD provides 8 cores with 16 threads. This means the Intel part relies on a hybrid arrangement with two additional physical cores to achieve its thread count, whereas AMD reaches 16 threads through simultaneous multithreading on 8 cores.

Cache hierarchies also diverge substantially. Intel allocates 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Intel's larger per-core L2 and total L3 allocations suggest a design favoring larger working sets, while AMD's smaller cache footprint is paired with a more advanced process node.

Memory support differs: Intel supports both DDR4 and DDR5, while AMD supports only DDR5. Both use dual-channel memory buses. AMD lists a memory bandwidth of 76.8 GB/s, while Intel does not provide a bandwidth figure. PCIe connectivity also varies, with Intel offering Gen 5 with 8 lanes (CPU only) and AMD offering Gen 4 with 20 lanes (CPU only).

Integrated graphics differ as well: Intel includes UHD Graphics 770, while AMD includes Radeon 680M. Neither processor supports ECC memory, and both are locked (multiplier not unlocked). The Intel part has a listed launch MSRP of $502, while no launch MSRP is provided for the AMD part.

Head-to-Head Benchmarks

The Intel Core i7-13620H dominates most synthetic tests, starting with 3DMark results. In the 2-thread test, Intel scores 1963 versus AMD's 1695, a 15.8% lead. The 4-thread test shows Intel at 3621 against 3214, a 12.7% margin. Single-thread performance in 3DMark favors Intel by 15.6%, with scores of 1008 and 872. The 8-thread test is close, with Intel ahead by just 0.9% (5443 vs 5392). The 16-thread test gives Intel a 7.6% win (7056 vs 6560), and the max-thread test shows a 9.9% advantage (7178 vs 6532).

Cinebench results reinforce Intel's lead. In Cinebench R23 multi-core, Intel scores 15176 versus AMD's 13094, a 15.9% difference. Single-core in R23 shows Intel at 1833 against 1542, an 18.9% margin — the largest Cinebench gap. Cinebench R15 multi-core gives Intel a 6.8% win (2281 vs 2136), while R15 single-core shows Intel ahead by 8.5% (263 vs 242.5).

PassMark tests reveal a split. Intel wins floating-point math decisively, scoring 59762 versus 47989, a 24.5% margin. The physics test is even more lopsided, with Intel at 1671 and AMD at 1046, a 59.8% advantage. Find prime numbers favors Intel heavily, 99 to 57, a 73.7% margin. Multithread performance gives Intel a 4.9% win (24192 vs 23060), and single-thread tests show Intel ahead by 11.7% (3589 vs 3212).

Where Each One Wins

The Intel Core i7-13620H is the clear choice for single-threaded and lightly-threaded workloads. Its 18.9% lead in Cinebench R23 single-core and 15.6% margin in 3DMark single-thread indicate strong per-core performance, likely benefiting from its higher 4.90 GHz boost clock and larger cache allocations. Applications that rely on floating-point math, such as scientific computing or physics simulations, see substantial Intel advantages: 24.5% in floating-point math and 59.8% in the physics test. The 73.7% margin in prime number finding further underscores Intel's integer-heavy compute strength in isolated tasks.

For heavily threaded general productivity, Intel also holds the edge. The 15.9% win in Cinebench R23 multi-core and 9.9% in 3DMark max-thread suggest the extra two physical cores provide a meaningful boost in scalable workloads. The 4.9% PassMark multithread win confirms this trend, though the margin narrows compared to pure multi-core rendering tests. Users running video encoding, 3D rendering, or compilation tasks would likely see consistent Intel advantages based on these figures.

The AMD Ryzen 7 6800H wins in specific data-processing scenarios. Its 14.7% lead in data encryption and 12.9% advantage in extended instructions indicate a strong cryptography and SIMD execution pipeline. The 5.2% win in integer math and 4.3% edge in data compression suggest AMD's Zen 3+ cores handle certain algorithmic workloads more efficiently, possibly aided by the higher 3.20 GHz base clock. Random string sorting also favors AMD by 4.2%, pointing to memory-access patterns that benefit from its architecture.

For users prioritizing raw multi-core throughput in professional applications, Intel's 16 wins out of 21 benchmarks make it the safer default. However, AMD's victories in encryption and compression could tip the balance for security-focused workloads or database operations. The AMD part also offers a more advanced 6 nm process and broader PCIe Gen 4 lane count (20 vs 8), which may matter for systems requiring extensive I/O connectivity. Ultimately, the choice depends on workload mix: Intel for compute-heavy, floating-point, and single-threaded tasks; AMD for data manipulation, cryptography, and integer-heavy processing.
