AMD Ryzen 5 9600X vs AMD Ryzen 7 7840HS Comparison

The AMD Ryzen 7 7840HS and AMD Ryzen 5 9600X are both 81st percentile CPUs, but they achieve that standing through very different strategies. The 7840HS is a mobile 8-core part that wins on integer-heavy and encryption workloads, while the 9600X is a desktop 6-core part that dominates in single-threaded and most multi-threaded tests. The benchmark data shows that the 9600X wins 19 of 23 head-to-head comparisons, but the 7840HS takes four decisive victories in specialized tasks.

Head-to-Head Benchmarks

The single biggest gap in the entire comparison comes in the PassMark find prime numbers test. The Ryzen 5 9600X scores 233 against the 7840HS’s 88, a 62.2% advantage. This is not a marginal lead; it is a generational leap in integer throughput per core, likely reflecting the Zen 5 architecture’s improved execution resources. The 9600X also crushes the 7840HS in Geekbench single-core, scoring 2923 versus 2031, a 30.5% delta. This pattern repeats across nearly every single-threaded metric: 3DMark single-thread shows a 21.9% lead (1253 vs 979), Cinebench R23 single-core shows a 19.3% lead (2183.5 vs 1761), and PassMark single-thread shows a 17.9% lead (4570 vs 3753).

The multi-core picture is more nuanced but still favors the 9600X. Despite having only 6 cores and 12 threads versus 8 cores and 16 threads, the 9600X wins Cinebench R23 multi-core by 13.8% (17528.5 vs 15102) and Geekbench multi-core by 18% (14438 vs 11846). The 3DMark results tell a similar story: at 16 threads the 9600X leads by 3.6% (7585 vs 7314), and at max threads it leads by 3.6% (7590 vs 7316). The 7840HS’s two extra cores cannot overcome the 9600X’s higher clocks and architectural efficiency.

However, the 7840HS does win four head-to-head tests, and these are not trivial. The largest win is in PassMark data encryption, where the 7840HS scores 20627 versus 16638, a 24% advantage. This suggests the mobile chip’s integrated security features or memory subsystem handle cryptographic workloads more effectively. The 7840HS also wins PassMark integer math by 9.7% (98682 vs 89918), PassMark random string sorting by 12.3% (40364 vs 35946), and PassMark data compression by a narrow 1.3% (345536 vs 341021). These wins indicate that for certain parallel integer workloads, the 8-core configuration provides a real benefit that the 9600X cannot match.

In the remaining tests, the 9600X’s margins vary widely. The 3DMark 2-thread test shows a 22.5% lead (2456 vs 1904), while the 4-thread test shows a 21.5% lead (4649 vs 3651). PassMark physics gives the 9600X a 31.6% advantage (2012 vs 1376), and the extended instructions test shows an 8.1% lead (28023 vs 25747). Even the closest multi-threaded contest, PassMark floating point math, goes to the 9600X by just 0.3% (60081 vs 59921). The 9600X also wins PassMark multi-thread overall by 4.6% (30027 vs 28633).

The Verdict

The data is unambiguous: the Ryzen 5 9600X is the faster processor in the vast majority of scenarios. It wins 19 of 23 benchmarks, including every single-threaded test and most multi-threaded tests. The 9600X’s victory in Cinebench R23 multi-core, despite having two fewer cores, is the clearest evidence of its architectural superiority. The 7840HS’s wins are confined to four specific workloads: encryption, integer math, random string sorting, and data compression. For general-purpose computing, gaming, and content creation, the 9600X is the clear choice.

That said, the 7840HS is not a poor performer. Its average benchmark score is 29955, which is only 0.8% lower than the 9600X’s 29713. The two chips occupy the same percentile tier, and the 7840HS’s 8-core design gives it an edge in specific parallel workloads. The 7840HS also carries the Radeon 780M integrated graphics, which is a more capable iGPU than the 9600X’s Radeon Graphics. For a mobile user who needs strong encryption performance or heavy integer math, the 7840HS is the better fit.

The choice comes down to workload priority. If you need maximum single-thread speed and the best overall multi-thread performance, the 9600X is the winner. If you need a mobile chip that excels at encryption, integer-heavy tasks, and data compression, the 7840HS has the edge. The 9600X also offers an unlocked multiplier, making it the more flexible option for overclocking.

Where Each One Wins

The Ryzen 5 9600X wins in almost every conventional computing category. Single-threaded performance is the most lopsided area, with the 9600X leading by 17.9% to 30.5% across different benchmarks. This translates directly to faster application launches, snappier web browsing, and better performance in lightly-threaded games. The 9600X also wins in multi-threaded rendering tasks, as shown by its 13.8% lead in Cinebench R23 multi-core and 18% lead in Geekbench multi-core. For video editing, 3D rendering, and software compilation, the 9600X is the stronger consumer.

The Ryzen 7 7840HS carves out a niche in four specific areas. Its 24% lead in PassMark data encryption makes it the better choice for VPN software, encrypted storage, and secure communications. The 12.3% win in random string sorting suggests an advantage in database operations and text processing. The 9.7% win in integer math points to strength in scientific computing and financial modeling. The 1.3% win in data compression is marginal but consistent with the pattern: the 7840HS handles certain parallel integer workloads better than the 9600X.

It is importantly the 7840HS’s wins are all in PassMark subtests, while the 9600X dominates in 3DMark, Cinebench, and Geekbench. This suggests the 7840HS’s strength is in specific computational patterns rather than general-purpose performance. Users who run heavily-threaded integer workloads should consider the 7840HS, but for everyone else, the 9600X is the safer bet.

Architecture Differences

The two CPUs are built on the same 4nm TSMC process node, but they represent different architectural generations. The 7840HS uses Zen 4 architecture with the Phoenix codename, while the 9600X uses Zen 5 architecture with the Granite Ridge codename. This generational difference is the primary reason for the 9600X’s performance advantage despite having fewer cores.

The cache configurations differ significantly. The 7840HS has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The 9600X has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The 9600X’s doubled L3 cache (32 MB vs 16 MB) provides a substantial advantage in workloads that benefit from larger cache footprints.

The transistor counts and die sizes also reflect their different designs. The 7840HS has 25,000 million transistors on a 178 mm² die, while the 9600X has 8,315 million transistors on a 70.6 mm² die. The 7840HS is a much larger chip, which is typical for an 8-core mobile processor with a powerful iGPU. The 9600X’s smaller die size and lower transistor count highlight the efficiency of the Zen 5 architecture.

The PCIe support differs as well. The 7840HS supports PCIe Gen 4 with 20 lanes, while the 9600X supports PCIe Gen 5 with 24 lanes. This gives the desktop chip twice the bandwidth for high-speed storage and graphics cards. Both CPUs support DDR5 memory, dual-channel memory buses, and ECC memory, with identical memory bandwidth of 89.6 GB/s.

Specification Differences

The most obvious specification difference is core count: the 7840HS has 8 cores and 16 threads, while the 9600X has 6 cores and 12 threads. The 9600X compensates with higher clocks: its base clock is 3.90 GHz versus 3.80 GHz, and its boost clock is 5.40 GHz versus 5.10 GHz. The 9600X also has a much higher TDP of 65 watts compared to the 7840HS’s 35 watts, reflecting its desktop orientation.

The sockets are incompatible. The 7840HS uses AMD Socket FP8, while the 9600X uses AMD Socket AM5. The 7840HS is a mobile processor, while the 9600X is a desktop processor. The 9600X has an unlocked multiplier, making it overclockable, while the 7840HS does not. The 9600X was released on 2024-08-07 and has a launch MSRP of $279; the 7840HS has no listed release date or launch MSRP.

The integrated graphics differ in name and likely capability. The 7840HS features Radeon 780M, while the 9600X features Radeon Graphics. The 7840HS’s part number is 100-000000955(FP7r2)100-000000964(FP7)100-000001129(FP8), while the 9600X’s part number is 100-000001405. Both are active production parts from AMD, but they target entirely different market segments: mobile versus desktop.
