AMD Ryzen 3 8300G vs AMD Ryzen AI 9 365 Comparison

Head-to-Head Benchmarks

The benchmark data delivers a one-sided result: the AMD Ryzen AI 9 365 wins every single recorded head-to-head test against the AMD Ryzen 3 8300G. Across fifteen benchmark comparisons, the Ryzen AI 9 365 takes all fifteen wins, with the Ryzen 3 8300G recording zero victories. The margin varies widely by workload, from a narrow single-thread edge to a dominant multi-thread lead.

The largest gap appears in PassMark integer math. The Ryzen AI 9 365 scores 101,831 against the Ryzen 3 8300G's 40,534, a delta of -60.2% (meaning the 8300G trails by that percentage). Floating point math shows a similar chasm: 62,802 versus 25,336, a -59.7% difference. Prime number finding also favors the larger chip heavily, with the Ryzen AI 9 365 at 117 and the Ryzen 3 8300G at 47, a -59.8% delta.

Cinebench multi-thread results reinforce the pattern. In Cinebench R15 multi-core, the Ryzen AI 9 365 posts 2,842 against the Ryzen 3 8300G's 1,231, a -56.7% gap. The R23 multi-core run shows 18,698 versus 12,217, a -34.7% delta. These are substantial margins that reflect the core and thread count disparity between the two processors.

Single-thread performance tells a different story. The Ryzen AI 9 365 still wins, but by much slimmer margins. In PassMark single-thread, the scores are 3,841 versus 3,778, a mere -1.6% difference. Cinebench R23 single-core shows 1,992 versus 1,724, a -13.5% gap. The R15 single-core test records 303 versus 173, a -42.9% delta, which is the largest single-thread gap in the dataset. The Ryzen AI 9 365's higher boost clock of 5.00 GHz versus 4.90 GHz likely contributes here, though the architectural differences also play a role.

Other workloads show consistent leads for the Ryzen AI 9 365. Data compression scores 354,510 versus 158,952, a -55.2% delta. Data encryption hits 18,297 versus 9,115, a -50.2% gap. Extended instruction performance reaches 25,113 versus 12,354, a -50.8% difference. Random string sorting, a test sensitive to memory and cache behavior, shows 39,447 versus 19,013, a -51.8% delta. Physics simulation records 1,704 versus 755, a -55.7% gap. The PassMark multithread score lands at 29,467 versus 14,018, a -52.4% difference.

Where Each One Wins

The Ryzen AI 9 365 wins decisively in every recorded category, but the nature of those wins splits into two distinct patterns. Multi-threaded and compute-heavy workloads show the largest advantages. The 10-core, 20-thread configuration delivers roughly double the performance of the 4-core, 8-thread Ryzen 3 8300G in integer math, floating point math, data compression, and encryption. These are workloads that scale with core count and memory bandwidth, and the data confirms the Ryzen AI 9 365's dominance there.

The Ryzen 3 8300G does not win a single test, but its closest relative performance appears in single-thread workloads. The PassMark single-thread score of 3,778 versus 3,841 is nearly a dead heat, with only a -1.6% delta. For lightly threaded tasks that rely on a single core, the gap narrows to a few percentage points. The Ryzen 3 8300G's higher base clock of 3.40 GHz versus 2.00 GHz helps close the distance, even though the boost clocks are close (4.90 GHz versus 5.00 GHz).

The use-case split follows these patterns. For professional rendering, data processing, encryption, or any heavily parallel workload, the Ryzen AI 9 365 is the clear choice based on the recorded margins. For everyday desktop responsiveness, web browsing, and single-threaded applications, the Ryzen 3 8300G remains competitive, trailing by only 1.6% on PassMark single-thread. The Ryzen 3 8300G also operates in a desktop socket (AM5) with a 65W TDP, while the Ryzen AI 9 365 is a mobile part (FP8 socket, 28W TDP). That difference matters for system design, but the raw performance data consistently favors the Ryzen AI 9 365.

Architecture Differences

The two processors come from different generations and designs. The Ryzen 3 8300G uses the Zen 4 architecture on the Phoenix2 codename, built on a 4nm TSMC process. It packs 4 cores and 8 threads, with a die size of 137 mm² and 20,900 million transistors. The Ryzen AI 9 365 uses the newer Zen 5 architecture on the Strix Point codename, also on a 4nm TSMC process, but with 10 cores and 20 threads across a larger 233 mm² die. The transistor count for the Ryzen AI 9 365 is not listed in the database.

Cache configurations differ significantly. The Ryzen 3 8300G has 64 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of shared L3 cache. The Ryzen AI 9 365 has 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The larger L3 cache on the Ryzen AI 9 365, combined with double the cores, explains part of the multi-thread advantage. The Ryzen AI 9 365 also uses a heterogeneous core design (Zen 5 / Zen 5c) per its generation label, which allows it to balance performance and efficiency cores.

Memory support varies as well. The Ryzen 3 8300G supports DDR5 only, with dual-channel memory and a measured bandwidth of 83.2 GB/s. The Ryzen AI 9 365 supports both DDR5 and LPDDR5X, also dual-channel, with a slightly higher bandwidth of 89.6 GB/s. ECC memory is supported on the Ryzen 3 8300G but not on the Ryzen AI 9 365. PCIe lanes differ: the Ryzen 3 8300G offers Gen 4 with 14 CPU lanes, while the Ryzen AI 9 365 offers Gen 4 with 16 CPU lanes.

Integrated graphics also differ. The Ryzen 3 8300G includes a Radeon 740M, while the Ryzen AI 9 365 steps up to a Radeon 880M. Both are integrated solutions, but the Radeon 880M represents a newer generation. The market segments differ as well: the Ryzen 3 8300G is a desktop part on socket AM5, while the Ryzen AI 9 365 is a mobile part on socket FP8. The Ryzen 3 8300G launched on 2024-01-07 with a launch MSRP of $176; the Ryzen AI 9 365 launched on 2024-06-30 with no launch MSRP listed. Neither processor has an unlocked multiplier.

The Verdict

The data points to a straightforward conclusion for most workloads. The AMD Ryzen AI 9 365 outperforms the AMD Ryzen 3 8300G in every recorded benchmark, with multi-threaded tasks showing leads of 34% to 60%. Its 10 cores and 20 threads, paired with 16 MB of L3 cache and higher boost clock, deliver substantially higher scores in rendering, encryption, compression, and math-heavy applications. The Ryzen AI 9 365 also lands in the 87th percentile of all CPUs in the database, compared to the Ryzen 3 8300G's 72nd percentile. Its average benchmark score of 40,048 is more than double the Ryzen 3 8300G's 18,169.

The Ryzen 3 8300G remains relevant only in specific desktop scenarios. Its single-thread performance trails by just 1.6% on PassMark, making it a viable option for lightly threaded desktop use where the AM5 socket and ECC memory support matter. It also has a lower launch MSRP of $176, though pricing comparisons are outside the scope of this analysis. The Ryzen 3 8300G's 65W TDP suits desktop cooling, while the Ryzen AI 9 365's 28W TDP targets mobile efficiency.

For users building a desktop system with AM5 compatibility and modest multi-thread demands, the Ryzen 3 8300G offers a functional baseline. For anyone needing serious compute throughput, the Ryzen AI 9 365's benchmark results are unambiguous: it wins every recorded test, often by wide margins. The choice depends on whether the workload is single-threaded desktop use or parallel processing. The database records no scenario where the Ryzen 3 8300G comes out ahead.
