AMD Ryzen 5 5600XT vs AMD Ryzen 7 7840HS Comparison

The Verdict

The data splits this comparison cleanly by workload type. The AMD Ryzen 7 7840HS wins 12 of the 15 recorded head-to-head benchmarks, dominating in most throughput and memory-sensitive tasks. The AMD Ryzen 5 5600XT wins only 3 benchmarks, but those wins are decisive in specific areas: Cinebench R23 multi-core, Cinebench R23 single-core, and PassMark's find prime numbers test.

For users prioritizing all-round performance in a mobile platform, the Ryzen 7 7840HS is the clear choice based on the benchmark record. It leads by substantial margins in data compression (34.4%), encryption (29.4%), extended instructions (47.5%), floating point math (47.8%), integer math (38.9%), multithread (28.5%), and random string sorting (51.2%). The Ryzen 5 5600XT, despite being a desktop part with a higher TDP, only manages to surpass the mobile chip in three specific tests, two of which are single-core oriented.

However, the Ryzen 5 5600XT should not be dismissed. Its 33.4% lead in Cinebench R23 single-core and 19.3% lead in Cinebench R23 multi-core are significant, indicating a strong showing in certain rendering and lightly-threaded workloads. The verdict is not about overall superiority; it is about matching the chip to the task. The 7840HS is the better all-rounder; the 5600XT is the specialist for specific compute patterns.

Where Each One Wins

The AMD Ryzen 7 7840HS wins in the majority of measured workloads. Its biggest advantages come in memory-intensive and parallel tasks. Random string sorting shows a 51.2% lead, floating point math a 47.8% lead, and extended instructions a 47.5% lead. These results indicate a processor that excels at data manipulation, mathematical computation, and workloads that leverage modern instruction sets.

The 7840HS also wins in integer math (38.9%), data compression (34.4%), and data encryption (29.4%). Its PassMark multi-thread score is 28.5% higher. Even in single-thread PassMark tests, it leads by 8.2%. The Cinebench R15 results also favor the 7840HS, with a 17.8% lead in multi-core and a 3% lead in single-core. The 7840HS is the choice for general productivity, content creation, and any workload that benefits from higher memory bandwidth and more cores.

The AMD Ryzen 5 5600XT wins in three specific areas. Its biggest win is PassMark find prime numbers, where it leads by 38.5%. This suggests a strong showing in integer-heavy, latency-sensitive single-threaded loops. The Cinebench R23 results are also notable: a 33.4% lead in single-core and a 19.3% lead in multi-core. These wins indicate that for certain rendering tasks and for applications that scale well with the larger 32 MB L3 cache, the 5600XT can outperform the 7840HS despite having fewer cores.

The 5600XT is the pick for users whose primary workloads match those three test patterns. The Cinebench R23 multi-core win is particularly relevant for rendering, and the single-core win matters for lightly-threaded applications. However, the overall benchmark record shows the 7840HS wins 12 of 15 tests, making it the more versatile processor for mixed-use scenarios. The 5600XT is a specialist; the 7840HS is the generalist with a broader winning profile.
