AMD Ryzen 3 4100 vs AMD Ryzen 3 7320C Comparison

The AMD Ryzen 3 4100 and AMD Ryzen 3 7320C are both quad-core, eight-thread Zen 2 processors, but they target entirely different segments: the 4100 is a desktop chip for Socket AM4, while the 7320C is a mobile part for Socket FT6. The benchmark data reveals a decisive performance gap, with the 4100 winning 16 of 17 head-to-head tests. The 7320C claims only a single victory, in random string sorting, where it scores 16,973 against the 4100's 15,760, a 7.1% advantage. Every other comparison favors the 4100, often by substantial margins, making this less a contest and more a demonstration of how different design priorities—desktop power versus mobile efficiency—shape real-world capability.

Head-to-Head Benchmarks

The most striking pattern is the consistency of the 4100's lead across rendering workloads. In Cinebench R23 multi-core, the 4100 scores 9,394 versus the 7320C's 7,025, a 33.7% difference. This margin repeats almost exactly across the other multi-threaded Cinebench tests: R20 shows 3,945 vs 2,950 (33.7% delta), and R15 shows 946 vs 708 (33.6% delta). Single-core Cinebench results follow the same trend, with the 4100 leading by 33.8% in R23 (1,326 vs 991), 33.7% in R20 (556 vs 416), and 34.3% in R15 (133 vs 99). These figures indicate a consistent architectural and clock-speed advantage, not a workload-specific anomaly.

The gap widens dramatically in certain PassMark sub-tests. The 4100's score of 9,923 in extended instructions is 170.9% higher than the 7320C's 3,663, the largest delta in the entire dataset. Data encryption shows a 67.8% lead (9,133 vs 5,443), and floating-point math favors the 4100 by 35.9% (19,128 vs 14,071). Even in prime number finding, a test often sensitive to memory latency, the 4100 leads by 27.8% (23 vs 18). These results suggest the 4100's larger L3 cache and higher base clock provide compounding benefits for compute-heavy tasks.

The narrowest margins are found in integer math, where the 4100 scores 32,307 against the 7320C's 32,247, a mere 0.2% difference. This near-tie indicates that for pure integer arithmetic, the two chips are functionally equivalent, likely due to identical core architecture and similar boost clocks. Single-thread PassMark results also stay close, with the 4100 at 2,531 and the 7320C at 2,439 (3.8% delta). The multi-thread PassMark score shows a 33.7% advantage for the 4100 (11,050 vs 8,265), aligning with the Cinebench multi-core results and confirming that the 4100's advantage scales with thread count.

The 7320C's sole win in random string sorting (16,973 vs 15,760) is notable but isolated. It suggests that the 7320C's memory subsystem, paired with LPDDR5, handles certain sequential operations more efficiently. However, this single 7.1% advantage does little to offset the 4100's dominance elsewhere. The overall average benchmark score reflects this: the 4100 averages 14,505 across all tests, while the 7320C averages 14,277, a 1.6% difference that understates the per-test volatility.

Where Each One Wins

The Ryzen 3 4100 wins in every multi-threaded rendering test, every single-core Cinebench test, and the vast majority of PassMark sub-tests. Its victories fall into three categories: sustained multi-core workloads (Cinebench R15/R20/R23 multi-core, PassMark multi-thread), single-core responsiveness (all Cinebench single-core tests, PassMark single-thread), and specialized compute (encryption, extended instructions, floating-point math). This makes it the clear choice for desktop users who run video encoding, 3D rendering, or any software that leverages multiple threads and high clock speeds. Its 3.80 GHz base and 4.00 GHz boost clocks, combined with 8 MB of L3 cache, provide the headroom needed for these tasks.

The Ryzen 3 7320C wins only in random string sorting, a narrow benchmark that involves memory access patterns and pointer chasing. Its 88.0 GB/s memory bandwidth—nearly 73% higher than the 4100's 51.2 GB/s—likely explains this result, as LPDDR5 offers faster data transfer for sequential operations. However, this advantage does not translate to other memory-sensitive tests like prime number finding, where the 4100 leads by 27.8%. The 7320C's lower TDP of 15 watts (versus 65 watts for the 4100) makes it the more appropriate choice for fanless or passively cooled mobile devices, but the benchmark data shows no other computational strength.

For users prioritizing battery life and portability, the 7320C's design wins by default, not by performance. Its integrated Radeon 610M graphics provide a display output capability that the 4100 lacks entirely, but this is a feature difference, not a processing advantage. In every measurable CPU benchmark except one, the 4100 is faster, often dramatically so.

Architecture Differences

Both chips use the Zen 2 architecture, but they are built on different processes and for different physical contexts. The 4100, codenamed Renoir, is manufactured on TSMC's 7 nm node with a die size of 156 mm² and 9,800 million transistors. The 7320C, codenamed Mendocino, uses a 6 nm process with a smaller 100 mm² die; its transistor count is not listed. This process shrink allows the 7320C to operate at a much lower TDP of 15 watts, compared to the 4100's 65 watts, while still delivering a slightly higher boost clock of 4.10 GHz versus 4.00 GHz.

Cache configurations differ significantly. Both have 64 KB of L1 and 512 KB of L2 per core, but the 4100 has 8 MB of shared L3 cache, double the 7320C's 4 MB. This larger L3 cache is a primary driver of the 4100's superior performance in multi-threaded and cache-sensitive workloads. The 4100 supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth; the 7320C supports LPDDR5 with a dual-channel bus and 88.0 GB/s bandwidth. Despite the 7320C's higher theoretical bandwidth, the 4100's cache advantage and higher base clock compensate in most tests.

Socket and platform choices diverge completely. The 4100 uses AMD Socket AM4 and supports PCIe Gen 3 with 8 lanes, while the 7320C uses Socket FT6 and supports PCIe Gen 3 with only 4 lanes. The 4100 has an unlocked multiplier, enabling overclocking; the 7320C is locked. The 4100 lists a launch MSRP of $99, while the 7320C has no launch price data. The 4100 targets the desktop market segment, while the 7320C is a mobile part. Both lack ECC memory support and both are active in production, but their release dates differ: the 4100 launched on April 3, 2022, and the 7320C on May 22, 2023.

The Verdict

The benchmark data is unambiguous: the Ryzen 3 4100 is the superior processor for raw compute performance. It wins 16 of 17 head-to-head tests, with leads ranging from 0.2% in integer math to 170.9% in extended instructions. Its 33.7% advantage in Cinebench R23 multi-core and multi-thread PassMark scores demonstrates a consistent edge in both synthetic and real-world multi-threaded workloads. The 4100's higher base clock, double L3 cache, and unlocked multiplier make it the clear choice for desktop builders who need processing power for rendering, compilation, or any CPU-intensive task. Its launch MSRP of $99 positions it as a functional entry-level desktop part, though pricing details should not be considered further.

The Ryzen 3 7320C, despite its newer 6 nm process and higher memory bandwidth, cannot match the 4100's performance. Its sole victory in random string sorting is a niche result that does not compensate for its 33.7% deficit in multi-core Cinebench tests or its 67.8% shortfall in data encryption. The 7320C's 15-watt TDP and integrated Radeon 610M graphics make it suitable for thin-and-light laptops where power consumption is critical, but the data shows no computational advantage over the 4100. Users who prioritize battery life and portability should select the 7320C; users who prioritize performance should select the 4100. The 4100's 69th percentile ranking among all CPUs matches the 7320C's percentile, but the per-test deltas reveal a far more lopsided comparison than that aggregate statistic suggests.
