AMD Ryzen 5 8600G vs Intel Core i7-13620H Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen 5 8600G and Intel Core i7-13620H is a split decision. The Ryzen 5 8600G claims 12 wins, while the Intel part takes 11. But the margins tell a more interesting story than the raw win count.

The most dramatic difference appears in Cinebench R23. The Ryzen 5 8600G scores 21,503 in multi-core, versus the Intel Core i7-13620H's 15,176. That is a 41.7% advantage for AMD. The single-core gap is even larger: 3,035 versus 1,833, a 65.6% lead. These are not small margins; they represent a fundamental performance class difference in this workload.

Cinebench R20 follows the same pattern. AMD leads multi-core at 9,031 versus 8,305 (8.7% ahead) and single-core at 1,274 versus 1,172 (also 8.7% ahead). In Cinebench R15, the single-core result again favors AMD at 305 versus 263 (16% ahead), but the multi-core test flips: Intel wins 2,281 versus 2,167, a 5% edge.

The 3DMark results consistently favor Intel. In the 16-thread test, Intel scores 7,056 versus 6,199 (12.1% ahead). The max-threads test shows Intel at 7,178 versus 6,161, a 14.2% margin. Intel also wins the 2-thread, 4-thread, and 8-thread variants by 4.8%, 3.1%, and 4.7% respectively. Single-thread 3DMark is close: Intel at 1,008 versus AMD at 985, a 2.3% edge.

PassMark tests split the pair. AMD wins data compression (293,306 versus 281,335, 4.3% ahead), data encryption (17,181 versus 15,568, 10.4% ahead), extended instructions (22,610 versus 17,513, 29.1% ahead), multithread (25,294 versus 24,192, 4.6% ahead), random string sorting (35,067 versus 29,395, 19.3% ahead), and single-thread (3,878 versus 3,589, 8.1% ahead). Intel counters with floating-point math (59,762 versus 47,919, 19.8% ahead), integer math (80,948 versus 77,042, 4.8% ahead), physics (1,671 versus 1,450, 13.2% ahead), and find prime numbers (99 versus 96, 3% ahead).

The average benchmark scores reflect the overall parity: the Ryzen 5 8600G sits at 24,089, while the i7-13620H reaches 24,911. In the database's percentile ranking, the Intel part sits at the 77th percentile of all CPUs, one point above the AMD chip's 76th percentile.

Architecture Differences

The two processors come from entirely different design philosophies. The AMD Ryzen 5 8600G uses the Zen 4 architecture on a 4 nm TSMC process, under the Phoenix codename. It fits 6 cores and 12 threads into a 178 mm² die, with 25,000 million transistors. The Intel Core i7-13620H uses Raptor Lake-H architecture on Intel's 10 nm process, packing 10 cores and 16 threads.

Cache layouts differ substantially. AMD uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel uses 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The larger per-core L2 on Intel helps feed its higher core count, while AMD's shared L3 pool is smaller overall.

Clock speeds show the AMD chip running higher frequencies: 4.30 GHz base and 5.00 GHz boost, versus Intel's 2.40 GHz base and 4.90 GHz boost. The TDP rating goes the other way: AMD draws 65 watts, Intel is rated at 45 watts. This makes sense given their market segments: the Ryzen 5 8600G is a desktop part on AMD Socket AM5, while the i7-13620H is a mobile processor on Intel BGA 1744.

Memory support also diverges. The AMD chip supports DDR5 only, with dual-channel access and 83.2 GB/s bandwidth. The Intel part supports both DDR4 and DDR5, also dual-channel, though the database records no bandwidth figure for it. Neither chip supports ECC memory.

PCI Express connectivity differs by generation. AMD provides Gen 4 with 20 lanes (CPU only). Intel provides Gen 5 with 8 lanes (CPU only). The integrated graphics are different as well: AMD includes the Radeon 760M, while Intel has UHD Graphics 770.

The multiplier is unlocked on the AMD part, meaning it can be overclocked. The Intel chip has a locked multiplier. The Ryzen 5 8600G was released in January 2024 with a launch MSRP of $229. The i7-13620H came out a year earlier in January 2023, with a launch MSRP of $502. Both remain in active production.

Where Each One Wins

The AMD Ryzen 5 8600G dominates in rendering and synthetic single-thread workloads. Its Cinebench R23 multi-core score of 21,503 is 41.7% ahead of Intel, and the single-core margin of 65.6% is the largest win in the entire comparison. It also leads in PassMark multithread, compression, encryption, extended instructions, random string sorting, and single-thread tests. This makes it the stronger choice for CPU-bound productivity that relies on high-frequency single-core performance, as well as applications that benefit from strong instruction-level parallelism.

The Intel Core i7-13620H wins across the 3DMark suite, including the 16-thread, max-threads, 8-thread, 4-thread, and 2-thread variants. Its 14.2% lead in max-threads and 12.1% lead in 16-threads shows stronger scaling under heavy multi-threaded loads. It also takes PassMark floating-point math with a 19.8% margin, plus integer math, physics, and prime number finding. The higher core count and larger L3 cache give it an edge in workloads that spread across many threads, especially floating-point-heavy calculations.

The Cinebench R15 multi-core result is the only Cinebench test Intel wins, edging AMD by 5%. That test favors the Intel part's thread count, while the newer R20 and R23 versions clearly favor AMD's architecture.

The Verdict

The data points to two different buyers. The AMD Ryzen 5 8600G is the pick for anyone running Cinebench-style rendering workloads, single-thread-dependent applications, or general desktop productivity where frequency matters. Its 41.7% lead in Cinebench R23 multi-core and 65.6% lead in single-core are decisive. The unlocked multiplier adds flexibility for enthusiasts, and the desktop form factor on Socket AM5 allows for system-level upgrades. The launch MSRP of $229 is considerably lower than Intel's $502, though the database records no performance-per-dollar metric.

The Intel Core i7-13620H suits mobile users who need consistent multi-threaded performance in a 45-watt envelope. Its wins in every 3DMark test, including a 14.2% margin in max-threads, indicate stronger performance under sustained multi-threaded loads. The 10-core, 16-thread configuration with 24 MB of L3 cache gives it headroom for heavily parallel tasks, and the support for both DDR4 and DDR5 memory provides platform flexibility. The locked multiplier is a limitation, but the mobile segment rarely relies on overclocking.

The overall average scores are close: 24,911 for Intel versus 24,089 for AMD. The percentile ranking is also near, at 77 versus 76. This is not a case of one processor being clearly superior. It is a matter of workload. Rendering and single-thread tasks go to AMD. Heavy multi-thread scaling and floating-point math go to Intel. Choose based on the applications you actually run, not on the marketing material.
