AMD Ryzen 3 4300G vs AMD Ryzen Embedded V2546 Comparison

Both the AMD Ryzen 3 4300G and the AMD Ryzen Embedded V2546 are built on the same Zen 2 architecture and 7 nm process, yet they are configured for very different purposes. The benchmark data shows a clear split: the Ryzen 3 4300G wins 14 of 17 head-to-head comparisons, while the Ryzen Embedded V2546 wins only 3. The 4300G is the stronger choice for general desktop workloads, with consistent leads in every Cinebench test and most Passmark tasks. The V2546, however, takes decisive wins in specific math-heavy Passmark tests and offers a lower 35 W TDP. The data indicates that the 4300G is the better all-around performer for everyday computing, while the V2546 suits specialized embedded or power-sensitive workloads that benefit from its extra cores and specific instruction strengths.

The Verdict

From the benchmark data, the AMD Ryzen 3 4300G is the default recommendation for most users. It leads in all six Cinebench results, including a 2.2% advantage in multi-core R23 (8387 vs 8207) and a 2.2% edge in single-core R23 (1184 vs 1158). Its Passmark single-thread score of 2425 is 50.7% higher than the V2546’s 1609, a massive gap that makes the 4300G clearly superior for lightly threaded desktop tasks. The 4300G also wins in Passmark multithread (9849 vs 9656), physics (454 vs 441), and data compression (137681 vs 136097).

The AMD Ryzen Embedded V2546 is the pick only when specific conditions apply. Its six cores and twelve threads give it wins in Passmark integer math (30739 vs 29737, a 3.3% lead), floating point math (18534 vs 17577, a 5.2% lead), and find prime numbers (22 vs 20, a 9.1% lead). These are narrow but consistent wins in compute-heavy integer and floating-point workloads. Its 35 W TDP is also significantly lower than the 4300G’s 65 W, which matters for embedded or passively cooled systems — though no thermal or power-efficiency benchmarks are provided in the data.

For a typical desktop user, the 4300G’s consistent wins, higher clock speeds, and unlocked multiplier make it the obvious choice. The V2546 is a niche part for those who need its extra cores for specific math tasks or its lower TDP for constrained environments.

Architecture Differences

Both processors share the same fundamental architecture: Zen 2, codename Renoir, built on TSMC’s 7 nm process with 9,800 million transistors on a 156 mm² die. The core counts differ, however. The Ryzen 3 4300G has 4 cores and 8 threads, while the Ryzen Embedded V2546 has 6 cores and 12 threads. This explains the V2546’s wins in integer and floating-point math, where additional cores can be utilized.

Cache configuration also differs. Both have 64 KB of L1 and 512 KB of L2 per core, but the L3 cache is 4 MB shared on the 4300G versus 8 MB shared on the V2546. The larger L3 on the V2546 could contribute to its performance in certain repetitive math workloads, although the benchmark data does not isolate cache effects directly.

Clock speeds favor the 4300G. Its base clock is 3.80 GHz and boost clock is 4.00 GHz, compared to the V2546’s 3.00 GHz base and 3.95 GHz boost. This higher clock speed is the likely driver behind the 4300G’s massive single-thread lead of 50.7% in Passmark and its 2.2% to 2.6% advantages across all Cinebench single-core tests.

Memory support is identical in type and bandwidth: both use dual-channel DDR4 with 51.2 GB/s. The V2546 adds ECC memory support, which the 4300G lacks. PCIe lanes differ as well: the 4300G provides Gen 3 with 16 lanes (CPU only), while the V2546 provides Gen 3 with 20 lanes (CPU only).

The integrated graphics differ in naming and specifications. The 4300G uses Radeon Vega 6, while the V2546 uses Radeon Graphics 384SP. The data does not include any graphics benchmarks, so no performance comparison is possible. The V2546’s multiplier is locked, while the 4300G’s is unlocked, allowing overclocking on the 4300G. The sockets differ: AM4 for the 4300G and FP6 for the V2546, meaning they are not interchangeable in the same motherboard.

Where Each One Wins

The Ryzen 3 4300G wins in every Cinebench test, both multi-core and single-core, across R15, R20, and R23. The margin is consistent, ranging from 2.2% to 2.6%. This indicates a uniform advantage in rendering and general CPU throughput tasks that Cinebench measures. The 4300G also wins in Passmark multithread (9849 vs 9656, a 2% lead) and physics (454 vs 441, a 2.9% lead), suggesting better overall multi-threaded performance despite having fewer cores.

In Passmark single-thread, the 4300G’s score of 2425 versus 1609 gives it a 50.7% lead, the largest single margin in the entire comparison. This is a decisive win for any task that relies on single-core speed, such as legacy applications, many games (though no game benchmarks are provided), and general desktop responsiveness. The 4300G also wins in data compression (1.2% lead), data encryption (1.6% lead), extended instructions (4% lead), and random string sorting (4.1% lead).

The Ryzen Embedded V2546 wins in three Passmark tests: find prime numbers (22 vs 20, a 9.1% lead), floating point math (18534 vs 17577, a 5.2% lead), and integer math (30739 vs 29737, a 3.3% lead). These are all compute-heavy, core-scalable workloads. The V2546’s two additional cores and 8 MB L3 cache likely drive these wins. The data shows no wins for the V2546 in any Cinebench or single-thread test.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 3 4300G is in Passmark single-thread, where it scores 2425 against the V2546’s 1609, a 50.7% delta. This is the most dramatic difference in the entire dataset and highlights the 4300G’s strength in single-core workloads. The next biggest wins for the 4300G are smaller but consistent: a 4.1% lead in random string sorting (14503 vs 13926), a 4% lead in extended instructions (9148 vs 8799), and a 2.9% lead in physics (454 vs 441). In Cinebench, the 4300G wins all six tests with deltas between 2.2% and 2.6%, showing a uniform advantage across both multi-core and single-core rendering workloads.

The AMD Ryzen Embedded V2546’s biggest win is in find prime numbers, scoring 22 versus 20, a 9.1% delta. It also shows a 5.2% lead in floating point math (18534 vs 17577) and a 3.3% lead in integer math (30739 vs 29737). These wins are noteworthy because they occur in pure computational tasks that scale with core count, even though the V2546 loses in the more holistic Passmark multithread test (9656 vs 9849, a 2% deficit for the V2546). The pattern suggests that the V2546’s extra cores help in specific math-heavy loops but do not translate to an overall multithreaded advantage in the broader benchmark suite.
