AMD Ryzen 3 PRO 8300G vs AMD Ryzen 5 4600G Comparison

The AMD Ryzen 5 4600G and AMD Ryzen 3 PRO 8300G are both active desktop processors, but they represent very different approaches to the same 65W TDP envelope. The 4600G is a six-core Zen 2 part on the mature AM4 platform, while the 8300G is a four-core Zen 4 chip on the newer AM5 socket. Benchmark data shows a clear split: the older chip dominates multi-threaded and throughput workloads, while the newer chip takes single-threaded and physics-based tests.

Head-to-Head Benchmarks

The AMD Ryzen 5 4600G wins 13 of the 17 head-to-head benchmark comparisons, and its victories are often overwhelming. The largest margin comes in PassMark data encryption, where the 4600G scores 13,572 against the 8300G's 8,607, a 57.7% advantage. Data compression tells a similar story: 231,426 versus 150,567, a 53.7% lead. These are not marginal differences; they represent a fundamental throughput gap in workloads that scale with core count and memory bandwidth.

The Cinebench suite shows consistent, if smaller, wins for the 4600G. In Cinebench R23 multi-core, the 4600G scores 13,593 against 12,359 for the 8300G, a 10% advantage. The same 10% delta appears in Cinebench R23 single-core (1,919 versus 1,744), and the pattern holds across R15 and R20 in both multi-core and single-core tests. Interestingly, the 4600G even wins single-core Cinebench tests despite the 8300G having a higher boost clock. This suggests the older Zen 2 architecture holds its own in this specific rendering workload.

Integer math is another strong area for the 4600G: 50,723 versus 37,292, a 36% lead. Floating-point math follows with 29,947 versus 23,374, a 28.1% margin. Extended instructions favor the 4600G by 33.4% (15,280 versus 11,451), and multi-thread performance shows a 19.6% gap (15,992 versus 13,368). Random string sorting goes to the 4600G by 23.1% (24,246 versus 19,703).

The AMD Ryzen 3 PRO 8300G wins four benchmarks, and its victories are equally decisive. PassMark single-thread is the standout: 3,550 versus 2,653, a 25.3% lead for the 8300G. This is the largest single-thread margin in the comparison, and it reflects the newer Zen 4 core design. The 8300G also wins PassMark find prime numbers (47 versus 32, a 31.9% advantage) and PassMark physics (772 versus 676, a 12.4% lead). These wins show that the 8300G is not merely slower overall; it has specific strengths in single-threaded integer and physics calculations.

The Verdict

The data points to a clear recommendation based on workload. The AMD Ryzen 5 4600G is the better choice for users who run multi-threaded applications, content creation workloads, or any task that scales with core count. Its 6 cores and 12 threads give it a structural advantage that the 8300G's 4 cores and 8 threads cannot overcome, despite the newer architecture. The 4600G also has a higher average benchmark score overall (17,507 versus 17,278) and a higher percentile ranking among all CPUs (71 for both, but the 4600G's score is higher).

The AMD Ryzen 3 PRO 8300G is the pick for single-threaded performance and physics-based workloads. Its 25.3% lead in PassMark single-thread and 12.4% lead in PassMark physics make it the better option for lightly-threaded applications, legacy software, or games that rely on a single powerful core. However, the 8300G's overall average benchmark score is lower, and it loses the majority of comparisons. The 4600G also has a lower launch MSRP of $154, which is worth noting for system builders on a fixed budget.

For a general-purpose desktop processor, the Ryzen 5 4600G is the data-backed winner. Its 13 wins versus 4, combined with a 10% or greater lead in most multi-threaded tests, make it the more versatile processor. The 8300G is a niche part for users who prioritize single-thread speed above all else.

Architecture Differences

The two processors are built on fundamentally different platforms. The AMD Ryzen 5 4600G uses the Zen 2 architecture on a 7 nm TSMC process, codenamed Renoir, while the AMD Ryzen 3 PRO 8300G uses Zen 4 on a 4 nm TSMC process, codenamed Phoenix2. The 4600G has 6 cores and 12 threads, compared to the 8300G's 4 cores and 8 threads. The 4600G's base clock is 3.70 GHz with a boost of 4.20 GHz; the 8300G has a lower base of 3.40 GHz but a much higher boost of 4.90 GHz.

Cache configurations differ substantially. Both have 64 KB of L1 per core and 8 MB of shared L3, but the 4600G has 512 KB of L2 per core while the 8300G doubles that to 1 MB per core. The 4600G uses DDR4 memory with dual-channel support and 51.2 GB/s bandwidth, while the 8300G uses DDR5 with 83.2 GB/s bandwidth. The 8300G supports ECC memory; the 4600G does not.

The platform sockets are incompatible: the 4600G uses AMD Socket AM4, while the 8300G uses AMD Socket AM5. PCIe support also differs, with the 4600G offering Gen 3 with 20 lanes and the 8300G offering Gen 4 with 14 lanes. The transistor counts reflect the generational leap: the 4600G has 9,800 million transistors on a 156 mm² die, while the 8300G packs 20,900 million on a smaller 137 mm² die. Integrated graphics also differ: the 4600G has Radeon Vega 7, while the 8300G has Radeon 740M. The 4600G has an unlocked multiplier; the 8300G does not.

Where Each One Wins

The AMD Ryzen 5 4600G wins in every multi-threaded and throughput-heavy category. Data compression, encryption, integer math, floating-point math, extended instructions, random string sorting, and all Cinebench multi-core tests go to the 4600G. It also wins Cinebench single-core tests despite the 8300G's higher boost clock, and it has the higher overall average benchmark score (17,507 versus 17,278). The 4600G is the processor for content creation, rendering, data processing, and any workload that can use more than four cores.

The AMD Ryzen 3 PRO 8300G wins in single-threaded performance, prime number calculation, and physics simulations. Its 25.3% lead in PassMark single-thread is the largest margin of victory for either processor, and its 31.9% win in find prime numbers shows a strong integer pipeline. The 8300G also has a higher boost clock (4.90 GHz versus 4.20 GHz), DDR5 memory support with 83.2 GB/s bandwidth, and ECC memory capability. These features make it a better fit for lightly-threaded applications, physics-heavy simulations, or systems that require ECC memory support.

The 8300G's wins in physics and prime numbers point to a core design that excels at specific, latency-sensitive tasks. The 4600G's wins in encryption and compression point to raw throughput. Users who need maximum single-thread response should choose the 8300G; users who need maximum overall throughput should choose the 4600G. The data shows no clear winner for all scenarios, but the 4600G's 13 wins versus 4 give it the broader appeal for general desktop use.
