AMD Ryzen 3 PRO 8300G

The AMD Ryzen 3 PRO 8300G is a 4-core, 8-thread desktop processor built on the Zen 4 architecture and the Phoenix2 die, manufactured on TSMC's 4 nm process. With a 65 W TDP, an integrated Radeon 740M GPU, and support for DDR5 memory on the AM5 socket, it occupies a compact but capable niche in the desktop lineup. Benchmark data places it in the 76th percentile of all CPUs, with an average benchmark score of 18,567 — a figure that lands it within 0.5% of its nearest rivals, making it a tightly contested performer in its segment.

Benchmark Performance

The Ryzen 3 PRO 8300G delivers a Cinebench R23 multi-core score of 12,359 and a single-core score of 1,744. In Cinebench R20, the multi-core result is 5,190 and single-core is 732; in R15, multi-core is 1,245 and single-core is 175. These scores indicate a processor that is far stronger on a per-thread basis than its thread count might suggest. The single-core R23 result of 1,744 is competitive with many higher-core-count parts, while the multi-core score of 12,359 reflects the limits of a 4-core design under fully threaded workloads.

Passmark results reinforce this profile. The multi-thread score is 14,540, and the single-thread score is 3,844. Integer math reaches 40,469, floating-point math 25,293, and extended instructions 12,360. Data compression scores 163,197, data encryption 9,350, and random string sorting 20,343. Physics simulation yields 897, and prime number finding returns 54. These numbers show strong integer and floating-point throughput for a 4-core chip, with the single-thread Passmark score of 3,844 ranking among the better values in this class.

Against its nearest rivals, the 8300G is essentially tied. The AMD Ryzen 3 8300G (non-PRO) shows a delta of 0% with an average score of 18,570. The Intel Core i3-14100F also shows 0% delta at 18,574. The AMD EPYC 9255, a server part, is 0.2% higher (delta -0.2) with a score of 18,604, while the AMD Ryzen 5 4500 trails by 0.5% (delta +0.5) at 18,471. These deltas are within the noise of benchmark variance, meaning the 8300G performs effectively identically to the i3-14100F and the non-PRO 8300G in aggregate scores. The EPYC 9255’s slight edge is negligible, and the Ryzen 5 4500’s deficit is also minimal.

The percentile rank of 76 indicates that the 8300G outperforms roughly three-quarters of all tested CPUs. This is a strong showing for a 4-core part, driven largely by its excellent single-thread performance and efficient Zen 4 cores. The average benchmark score of 18,567 sits near the median of its rival group, confirming that the 8300G is a balanced performer rather than a specialist.

Power and Thermals

The 8300G carries a TDP of 65 W, placing it in the mainstream low-power segment. This TDP class typically requires only a modest air cooler — a standard tower cooler or a compact low-profile unit is sufficient to maintain rated performance. The 4 nm TSMC process (20,900 million transistors on a 137 mm² die) contributes to efficiency, though the integrated Radeon 740M GPU adds its own thermal load under graphics workloads. The processor is not multiplier-unlocked, so overclocking is not an option; users must rely on stock or motherboard-provided power limits.

The 65 W TDP also implies that the 8300G is well-suited to small-form-factor builds and systems where cooling is constrained. It does not demand the large coolers or liquid loops associated with higher-TDP parts. In sustained multi-threaded loads, the 4-core design will not generate extreme heat, and the single-core boost clock of 4.90 GHz is achievable within the thermal envelope. The base clock of 3.40 GHz provides a solid floor for power management.

Who Should Consider It

The Ryzen 3 PRO 8300G is best suited for users whose workloads are dominated by single-thread performance or lightly threaded tasks. The strong Cinebench R23 single-core score of 1,744 and Passmark single-thread score of 3,844 make it an excellent choice for everyday productivity, office applications, and web browsing where responsiveness matters more than raw thread count. Gaming also benefits from the high single-core throughput, especially in titles that rely on one or two primary threads; the integrated Radeon 740M can handle light gaming without a discrete GPU, though demanding 3D titles will require an add-in card.

For content creation, the 8300G is a capable entry-level option. The multi-core R23 score of 12,359 is sufficient for photo editing, light video encoding, and compiling smaller projects, but it will struggle with heavily threaded workloads such as 3D rendering or multi-stream video processing. The data compression score of 163,197 and encryption score of 9,350 indicate solid performance for archiving and security tasks. The 8 MB shared L3 cache and 1 MB L2 per core help keep memory latency low, which benefits many real-world applications.

The PRO branding suggests business-oriented reliability features, such as ECC memory support (confirmed in the spec) and a long production status (Active). This makes it suitable for entry-level workstations or office PCs where data integrity is a priority. It is not the right choice for users who need heavy multi-threading; a 6-core or 8-core part would be better for that. But for a balanced desktop that handles daily tasks and occasional creative work, the 8300G is a strong contender.

Platform and Compatibility

The 8300G is built for AMD Socket AM5, the current mainstream desktop platform. It supports dual-channel DDR5 memory, with a maximum bandwidth of 83.2 GB/s, and includes ECC memory support — a feature often reserved for workstation or server parts. The memory bus is dual-channel, and the integrated memory controller is designed for DDR5 only, meaning older DDR4 modules are not compatible.

For expansion, the CPU provides 14 PCIe Gen 4 lanes. This is a modest lane count, typical for a 4-core part, and is sufficient for a single discrete GPU and one or two NVMe drives. The integrated Radeon 740M GPU uses some of these lanes for display output, though the exact allocation is not specified. The processor is not multiplier-unlocked, so overclocking is not possible; however, the AM5 platform itself may offer other tuning options such as memory overclocking.

The production status is Active, and the release date is April 15, 2024. The part number is 100-000001187. The 4 nm process and 137 mm² die size indicate a modern, efficient design. The AM5 socket is shared with other Ryzen processors, but the 8300G’s specific feature set — 4 cores, 8 threads, and integrated graphics — positions it as a lower-tier option within that ecosystem. Users seeking more cores or higher performance would need to step up to a different AM5 part.

Single-Thread vs Multi-Thread Behavior

The 8300G exhibits a pronounced single-thread advantage relative to its multi-thread capability. In Cinebench R23, the single-core score of 1,744 is 14.1% of the multi-core score of 12,359 — a ratio that reflects the 4-core/8-thread design. The Passmark results show a similar pattern: single-thread 3,844 versus multi-thread 14,540, a ratio of 26.4%. These ratios are typical for a part with a high boost clock (4.90 GHz) and a moderate core count.

This behavior means that the 8300G excels in workloads that are latency-sensitive or rely on a single fast thread. Application launches, spreadsheet recalculations, and web rendering all benefit from the high single-core performance. Conversely, heavily threaded tasks such as video rendering or 3D simulation will not scale as well, and the 8300G will lag behind processors with more cores, even those with lower per-core performance. The base clock of 3.40 GHz provides a solid foundation, and the boost clock of 4.90 GHz ensures that single-threaded bursts are fast.

The data compression score of 163,197 and encryption score of 9,350 suggest that the 8300G handles cryptographic and compression workloads efficiently, likely due to the Zen 4 architecture’s strong integer performance. The floating-point math score of 25,293 indicates capable, though not exceptional, FP throughput. For users who alternate between office tasks and occasional content creation, the 8300G’s single-thread strength will be more noticeable than its multi-thread limits.

How It Compares

AMD Ryzen 3 8300G (non-PRO): The PRO variant is essentially identical to the standard Ryzen 3 8300G, with a delta of 0% and average scores of 18,567 and 18,570, respectively. The only practical differences are the PRO branding and possibly business-oriented features, but the benchmark data shows no performance gap.

Intel Core i3-14100F: The i3-14100F matches the 8300G with a delta of 0% and an average score of 18,574. Both are 4-core/8-thread parts, and the aggregate benchmarks are within a few points. The 8300G offers integrated graphics, while the i3-14100F requires a discrete GPU; otherwise, performance is indistinguishable in this data.

AMD EPYC 9255: The EPYC 9255, a server processor, posts a score of 18,604, which is 0.2% higher than the 8300G (delta -0.2). This margin is negligible in real-world terms, though the EPYC is designed for entirely different workloads. The 8300G’s desktop-oriented features and lower power envelope make it a more practical choice for consumer systems.

AMD Ryzen 5 4500: The Ryzen 5 4500 scores 18,471, which is 0.5% lower than the 8300G (delta +0.5). Despite having two more cores (6 cores, 12 threads), the 4500’s older architecture and lower clock speeds result in slightly worse aggregate performance. The 8300G’s Zen 4 cores and higher boost clock give it the edge in both single-thread and overall benchmarks, making it a better choice for most desktop tasks.
