AMD Ryzen 7 7840U vs Intel Core i7-13620H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two mobile processors. The Intel Core i7-13620H claims victory in 14 of the 21 recorded head-to-head tests, while the AMD Ryzen 7 7840U secures 7 wins. The margin of victory, however, tells a more nuanced story than the raw win count.

Intel's most decisive victories come in multi-threaded and physics-based workloads. The 3DMark max threads test shows the Intel part scoring 7178 against AMD's 5402, a 24.7% advantage. Similarly, the PassMark physics test reveals a 24.8% gap, with Intel at 1671 versus AMD's 1256. The 3DMark 16 threads benchmark reinforces this pattern: Intel scores 7056, AMD 5427, a 23.1% difference. These results indicate that Intel's hybrid architecture with 10 cores provides substantial headroom in heavily threaded synthetic scenarios.

The Cinebench suite follows the same trajectory. In Cinebench R23 multi-core, Intel achieves 15176 while AMD manages 12719, a 16.2% lead. The older Cinebench R15 multi-core test shows Intel at 2281 against AMD's 1990, a 12.8% margin. Even in single-threaded Cinebench R23, Intel edges ahead with 1833 versus 1677.5, an 8.5% advantage. The 3DMark 2 threads test also favors Intel at 1963 versus 1729, an 11.9% gap, suggesting that Intel's per-core performance, particularly on its performance cores, holds a consistent edge.

AMD's victories, while fewer, are concentrated in specific computational domains. The PassMark extended instructions test shows AMD at 20432 versus Intel's 17513, a 16.7% lead. PassMark integer math reveals AMD at 90852 against Intel's 80948, a 12.2% advantage. PassMark random string sorting shows AMD at 33757 versus 29395, a 14.8% margin. Data encryption also favors AMD: 17691 versus 15568, a 13.6% lead. These results suggest that AMD's Zen 4 architecture excels in integer-heavy and encryption workloads, possibly reflecting superior instruction-level efficiency.

The narrowest margins are telling. Cinebench R15 single-core shows AMD at 264 versus Intel's 263, a razor-thin 0.4% difference. PassMark single-thread tests show Intel at 3589 versus AMD's 3565, only a 0.7% gap. These near-ties indicate that in purely single-threaded legacy workloads, the two processors are effectively interchangeable.

Where Each One Wins

The data suggests Intel's Core i7-13620H is the stronger choice for multi-threaded rendering, physics simulation, and general 3DMark-style workloads. The 3DMark results, particularly the 16-thread and max-thread tests, show Intel leading by margins between 23.1% and 24.7%. Cinebench R23 multi-core, a proxy for video rendering and 3D content creation, favors Intel by 16.2%. The PassMark physics test, which simulates rigid body dynamics, shows Intel ahead by 24.8%. These are workloads where core count and raw throughput matter most, and Intel's 10-core configuration delivers.

AMD's Ryzen 7 7840U wins in data compression (2.6% lead), data encryption (13.6% lead), extended instructions (16.7% lead), integer math (12.2% lead), and random string sorting (14.8% lead). These are workloads that benefit from efficient instruction execution and memory handling rather than raw core count. The PassMark multithread test also slightly favors AMD at 24782 versus 24192, a 2.4% margin, which is notable because it suggests that in certain mixed-thread workloads, AMD's 8-core, 16-thread design can match or exceed Intel's 10-core, 16-thread configuration.

For single-threaded legacy workloads like Cinebench R15 single-core, the two are statistically tied. The 0.4% delta falls within measurement noise. PassMark single-thread shows a similarly negligible 0.7% gap in Intel's favor.

Architecture Differences

The two processors represent fundamentally different design philosophies. AMD's Ryzen 7 7840U uses the Zen 4 architecture on TSMC's 4 nm process node, codenamed Phoenix. It packs 8 cores and 16 threads with a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The thermal design power is 28 W, reflecting its efficiency-focused positioning. The die size is 178 mm² with 25,000 million transistors. Cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3.

Intel's Core i7-13620H uses the Raptor Lake architecture on Intel's 10 nm process node, codenamed Raptor Lake-H. It features 10 cores and 16 threads with a base clock of 2.40 GHz and a boost clock of 4.90 GHz. The TDP is 45 W, substantially higher than AMD's. Cache includes 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. The socket is Intel BGA 1744, while AMD uses AMD Socket FP8. Intel supports both DDR4 and DDR5 memory, while AMD supports DDR5 only. AMD offers ECC memory support; Intel does not. Intel's PCIe implementation is Gen 5 with 8 lanes, while AMD uses Gen 4 with 20 lanes.

The integrated graphics also differ: AMD includes Radeon 780M, while Intel ships UHD Graphics 770. The release date for Intel is January 3, 2023; AMD's release date is not recorded in the database.

The Verdict

The recorded data indicates that the Intel Core i7-13620H is the superior processor for multi-threaded rendering and physics-heavy workloads. The 16.2% lead in Cinebench R23 multi-core and 24.8% lead in PassMark physics are substantial margins that would translate to real-world differences in video encoding, 3D rendering, and simulation tasks. The 3DMark results, with Intel ahead by 23.1% to 24.7% in multi-thread tests, reinforce this conclusion.

The AMD Ryzen 7 7840U, however, demonstrates clear advantages in specific computational domains. The 16.7% lead in extended instructions and 13.6% lead in data encryption suggest that AMD's Zen 4 architecture handles complex instruction sets and cryptographic workloads more efficiently. The 12.2% lead in integer math and 14.8% lead in random string sorting indicate superior integer processing capabilities.

For users prioritizing rendering performance, physics simulation, or general multi-threaded productivity, the data points to Intel. For those whose workloads involve encryption, integer-heavy calculations, or data compression, AMD offers measurable benefits. The single-threaded performance is effectively a tie, so legacy applications will not differentiate these processors.

The thermal design power difference, 28 W for AMD versus 45 W for Intel, is notable but should be interpreted qualitatively. The data does not specify cooling requirements or sustained performance under load.
