AMD Ryzen 3 4300U vs AMD Ryzen Embedded R2514 Comparison

The AMD Ryzen 3 4300U and AMD Ryzen Embedded R2514 are both quad-core AMD parts with a 15 W TDP, but benchmark data reveals they are engineered for entirely different workloads. The R2514 dominates multi-threaded rendering, while the 4300U delivers decisively stronger single-core performance. The data shows a split decision: the Embedded R2514 wins the two multi-core tests, and the 4300U wins the two single-core tests, resulting in a 2-2 tie in the head-to-head comparison.

Head-to-Head Benchmarks

The most significant victory in this matchup belongs to the AMD Ryzen Embedded R2514 in Cinebench R23 multi-core, where it scores 5984 against the 4300U's 3571. That is a 40.3% advantage, the largest delta in the entire head-to-head set. This is not a marginal lead; it signals that the R2514's extra threads (8 versus 4) translate into a substantial scaling advantage in heavily parallelized workloads. In the older Cinebench R15 multi-core test, the R2514 again takes the win, scoring 603 versus 562.5, a 6.7% margin. While smaller, this still confirms the multi-core trend across two different rendering generations.

The AMD Ryzen 3 4300U fights back decisively in single-core performance. In Cinebench R15 single-core, the 4300U scores 163.9 versus the R2514's 84, a staggering 95.1% advantage. This is the largest win for either chip and indicates a fundamental difference in per-core efficiency. The gap narrows in Cinebench R23 single-core, but the 4300U still leads with a score of 1074 against 844, a 27.3% advantage. The data suggests that while the R2514 can leverage its thread count for throughput, its individual cores are far less potent for latency-sensitive tasks.

Looking at broader averages, both processors land in the same competitive tier. The 4300U has an average benchmark score of 1742, while the R2514 sits at 1730. Both occupy the 41st percentile among all CPUs. Interestingly, both chips share a nearest rival in the Intel Core i3-1315UE, which scores 1739. The 4300U is 0.2% above that rival, while the R2514 is 0.5% below it. The R2514 also draws a near-identical comparison to the Intel Core i7-4860HQ, which scores 1720, putting the R2514 0.6% ahead. The 4300U matches the Intel Core i3-10100 exactly at 1742 with a 0% delta. These figures indicate that despite their architectural differences, neither chip enjoys a meaningful overall performance edge over the other; their strengths are simply distributed differently across test types.

Architecture Differences

The two processors represent different generations of AMD design. The Ryzen 3 4300U is built on the Zen 2 architecture with the codename Renoir, fabricated on a 7 nm process at TSMC. The Ryzen Embedded R2514 uses the older Zen+ architecture, codenamed Picasso, on a 12 nm process at GlobalFoundries. This node difference is significant: the 4300U packs 9,800 million transistors into a 156 mm² die, while the R2514 has 4,940 million transistors on a larger 210 mm² die. The newer process allows the 4300U to be denser and more power-efficient per transistor.

Core and thread counts are a major differentiator. The 4300U has 4 cores and 4 threads (no SMT), while the R2514 has 4 cores and 8 threads (with SMT). This explains the R2514's multi-core dominance. Cache configurations also differ. The 4300U has 64 KB of L1 cache per core, while the R2514 has 96 KB per core. Both share 512 KB of L2 per core and 4 MB of shared L3 cache. Clock speeds are another split: the 4300U has a base clock of 2.70 GHz and a boost clock of 3.70 GHz, while the R2514 starts lower at 2.10 GHz base but matches the 3.70 GHz boost. The lower base clock on the R2514, combined with its older architecture, contributes to its weaker single-core scores.

Memory and platform support diverge as well. The 4300U supports both DDR4 and LPDDR4 memory with a dual-channel bus and a bandwidth of 51.2 GB/s. The R2514 is limited to DDR4, also dual-channel, but with a lower bandwidth of 42.7 GB/s. The R2514 supports ECC memory, while the 4300U does not. Socket compatibility differs: the 4300U uses AMD Socket FP6, whereas the R2514 uses AMD Socket FP5. Both use PCIe Gen 3, but the R2514 specifies 16 lanes for the CPU only. Integrated graphics also differ, with the 4300U featuring Radeon Graphics 320SP and the R2514 featuring Radeon Vega 8.

The Verdict

The data presents a clear split based on workload type. The AMD Ryzen Embedded R2514 is the choice for multi-threaded, throughput-oriented tasks. Its 40.3% lead in Cinebench R23 multi-core is the defining statistic of this comparison, and its 8 threads provide a structural advantage that the 4300U cannot counter. This chip is positioned for embedded or desktop scenarios where sustained parallel processing is the priority.

The AMD Ryzen 3 4300U is the choice for single-threaded responsiveness and efficiency. Its 95.1% lead in Cinebench R15 single-core is a decisive indicator of per-core superiority, and its 7 nm process and higher base clock (2.70 GHz) suggest better power characteristics for mobile use. The 4300U is a mobile part, while the R2514 is a desktop-class embedded part, which aligns with their respective strengths.

For users who value raw multi-core rendering performance, the R2514 is the clear winner. For users who need snappy single-threaded application performance or operate in a mobile form factor, the 4300U is the better fit. The average benchmark scores (1742 for 4300U, 1730 for R2514) show they are equals overall, but the distribution of those scores could not be more different.

Where Each One Wins

The AMD Ryzen Embedded R2514 wins in multi-core rendering and parallel processing. It leads in both Cinebench R23 multi-core (5984 versus 3571) and Cinebench R15 multi-core (603 versus 562.5). Its 8 threads and 4 MB of shared L3 cache make it suitable for workloads that can utilize all threads, such as video encoding, 3D rendering, or server-side processing. It also supports ECC memory, making it viable for reliability-critical embedded applications where data integrity is paramount.

The AMD Ryzen 3 4300U wins in single-core performance and mobile efficiency. It leads in Cinebench R23 single-core (1074 versus 844) and Cinebench R15 single-core (163.9 versus 84). Its 7 nm process node and higher base clock of 2.70 GHz position it as the more responsive part for everyday tasks like web browsing, office productivity, or light coding. Its support for LPDDR4 memory and its mobile market segment make it the preferred option for laptops and portable devices, where its lower transistor count and smaller die size contribute to a more compact platform.
