AMD Ryzen 5 8600G vs AMD Ryzen 7 5800H Comparison

Head-to-Head Benchmarks

The benchmark database records a decisive overall victory for the AMD Ryzen 5 8600G, which wins 22 of the 23 head-to-head comparisons against the AMD Ryzen 7 5800H. The only exception is in PassMark integer math, where the 5800H scores 80786 against 77042, a 4.6% advantage. That single result, however, does little to offset the scale of the 8600G's dominance elsewhere.

The largest gaps appear in single-threaded and lightly threaded workloads. In Cinebench R23 single-core, the 8600G scores 3035 versus 1416, a staggering 114.3% lead. The Geekbench single-core result follows a similar pattern at 45.8% ahead, while the 3DMark single-thread test shows a 20.3% advantage. These are not marginal differences; they indicate a fundamental per-core performance gap that favors the newer architecture.

Multi-core results are more nuanced but still favor the 8600G, despite it having only 6 cores and 12 threads against the 5800H's 8 cores and 16 threads. In Cinebench R23 multi-core, the 8600G scores 21503 versus 12091.5, a 77.8 percent lead. Geekbench multi-core shows a 31.8 percent advantage (10850 versus 8230). The 3DMark 16-thread test is nearly a tie, with the 8600G just 0.9 percent ahead. The 3DMark max-threads result is similarly close at 0.6 percent, suggesting that when both processors are saturated with many threads, the core-count deficit of the 8600G nearly erases the per-core advantage.

Passmark results reinforce the pattern. The 8600G leads in multithread by 21.7 percent, in physics by 74.7 percent, in random string sorting by 24.6 percent, and in extended instructions by 24.2 percent. The prime numbers test shows a 95.9 percent lead, and data compression is 8.4 percent ahead. Even data encryption, which is often close, goes to the 8600G by 1.3 percent. The 5800H's only win is the integer math result, which is a notable but isolated point in an otherwise one-sided dataset.

Where Each One Wins

The AMD Ryzen 5 8600G is the clear winner in almost every category. Its strengths are most pronounced in single-threaded responsiveness, where it leads by between 20.3 and 114.3 percent across all single-thread tests. This makes it the better choice for applications that rely on per-core performance, such as everyday desktop use, office productivity, and lightly threaded creative workloads. The 8600G also wins all four Cinebench iterations, both Geekbench tests, and the majority of Passmark sub-tests, so it is the stronger processor for content creation, rendering, and general computing.

The AMD Ryzen 7 5800H wins exactly one test: Passmark integer math, where it scores 80786 against 77042. This is a specific workload that benefits from the extra two physical cores and four additional threads. In tasks that are purely integer arithmetic and can scale across many threads, the 5800H can outperform the 8600G. This is a narrow but real advantage, and it suggests that certain scientific or financial calculations could see a benefit from the 5800H's core count.

Beyond that single test, the 5800H's closest margins are in the heavily threaded 3DMark tests. The 16-thread test sees the 8600G win by only 0.9 percent, and the max-threads test by 0.6 percent. These are effectively ties, and they indicate that in a perfectly parallel workload that uses every available thread, the two processors are nearly equal. The 5800H's additional cores do allow it to keep pace with the 8600G in these specific cases, but they do not grant it a victory.

Architecture Differences

The two processors come from entirely different architectural eras. The AMD Ryzen 5 8600G is based on Zen 4, with the codename Phoenix, and is built on a 4nm process from TSMC. The AMD Ryzen 7 5800H uses the older Zen 3 architecture, codename Cezanne, and is manufactured on a 7nm process, also by TSMC. This process difference is one of the main reasons for the 8600G's performance advantage, as it allows for higher clock speeds and better power efficiency per instruction.

The 8600G has 6 cores and 12 threads, while the 5800H has 8 cores and 16 threads. The 5800H compensates for having more cores with a lower per-core performance ceiling. The 8600G has a much higher L2 cache per core at 1 MB per core, versus 512 KB per core on the 5800H. Both have the same L1 cache at 64 KB per core, and the same shared L3 cache at 16 MB. The 8600G also has a larger die size at 178 mm² versus 180 mm² for the 5800H, despite having fewer transistors: 25,000 million versus 10,700 million. This is a result of the denser 4nm process.

The integrated graphics also differ. The 8600G features a Radeon 760M, while the 5800H has a Radeon Vega 8. The 8600G's memory support is DDR5, with a dual-channel bus and a memory bandwidth of 83.2 GB/s. The 5800H uses DDR4, also dual-channel, but with a lower memory bandwidth of 68.3 GB/s. The PCIe interface on the 8600G is Gen 4 with 20 lanes (CPU only), while the 5800H has PCIe Gen 3. The 8600G has an unlocked multiplier, while the 5800H is locked.

Specification Differences

The two processors differ in nearly every key specification. The 8600G has a base clock of 4.30 GHz, which is significantly higher than the 5800H's 3.20 GHz. The boost clock is 5.00 GHz on the 8600G versus 4.40 GHz on the 5800H. The 8600G has a TDP of 65 watts, while the 5800H is a 45 watt part. The 8600G uses the AMD Socket AM5, while the 5800H uses AMD Socket FP6, reflecting the desktop versus mobile market split.

The 8600G is from the 8000 series and is a desktop processor, while the 5800H is from the 5000 series and is a mobile processor. The 8600G has a release date of 2024-01-07, while the 5800H was released on 2021-01-11. The 8600G supports DDR5 memory, while the 5800H only supports DDR4. The 8600G has a launch MSRP of $229. The 5800H has no recorded launch MSRP. The 8600G also has a higher memory bandwidth, 83.2 GB/s versus 68.3 GB/s. The 5800H has no PCIe lane count listed, only "Gen 3".

The Verdict

The data is unambiguous: the AMD Ryzen 5 8600G is the superior processor for the vast majority of use cases. It wins 22 of 23 benchmarks, with leads ranging from 0.6% up to 114.3%. The single-thread performance lead is the most striking, with Cinebench R23 single-core more than doubling the 5800H's score. This means that for any workload that does not scale perfectly to 16 threads, the 8600G will provide a noticeably faster experience.

The 5800H's only valid claim is in pure integer math, where its extra cores and threads result in a 4.6% win. In the multi-threaded 3DMark tests, the 5800H gets very close to the 8600G, but still loses. For a user doing heavy integer arithmetic, the 5800H could be considered, but that is a narrow niche. The 5800H's 8 cores and 16 threads are insufficient to overcome the 8600G's superior per-core architecture in nearly all measured workloads.

For a desktop user, the 8600G is the clear choice. For a user constrained to a mobile platform, the 5800H is the only one of the two that fits that form factor, but the data shows its performance is behind the desktop part. The 8600G also offers a more modern feature set with DDR5 and PCIe Gen 4, plus an unlocked multiplier for overclocking. The 5800H is a capable processor, but the 8600G is a different class of performer.
