AMD Ryzen 3 7320C vs AMD Ryzen Embedded V2546 Comparison

The AMD Ryzen Embedded V2546 and AMD Ryzen 3 7320C are closely matched overall, with average benchmark scores of 14336 and 14277 respectively — a gap of just 0.4%. Despite this near-parity in aggregate, the two chips have sharply divergent strengths. The V2546 wins 11 of 17 head-to-head tests, dominating multi-threaded workloads and encryption, while the 7320C takes 6 wins, including a decisive victory in single-thread performance and several memory-sensitive tasks. The data shows that the V2546 is the compute-heavy workhorse, whereas the 7320C is the efficiency-oriented part with superior single-core throughput.

Where Each One Wins

The AMD Ryzen Embedded V2546 is the clear winner in CPU-bound, multi-core scenarios. It leads by 16.8% in Cinebench R15, R20, and R23 multi-core tests, and by the same margin in PassMark multithread. Its advantage extends to floating-point math (18534 vs 14071, a 31.7% lead) and extended instruction workloads (8799 vs 3663, a massive 140.2% lead). Data encryption is another stronghold, with the V2546 scoring 8046 versus 5443 — a 47.8% advantage. Prime number finding also favors the V2546 by 22.2% (22 vs 18).

The AMD Ryzen 3 7320C wins in several specific workloads that highlight its architectural efficiency. Its most striking victory is in PassMark single-thread, scoring 2439 versus 1609 — a 34% lead. It also wins data compression (144465 vs 136097, a 5.8% edge), integer math (32247 vs 30739, a 4.7% lead), physics (500 vs 441, an 11.8% lead), and random string sorting (16973 vs 13926, an 18% advantage). These wins suggest the 7320C excels in tasks that rely heavily on memory bandwidth and per-core efficiency rather than raw core count.

The split is clear: the V2546 for sustained multi-threaded compute, the 7320C for single-thread responsiveness and memory-intensive operations. In overall average score, the two are separated by only 0.4%, making the choice workload-dependent rather than a clear overall winner.

Architecture Differences

Both processors are built on AMD’s Zen 2 architecture, but they are implemented in different packages and process nodes. The V2546 uses the larger Renoir die, fabricated on TSMC’s 7 nm process, with a die size of 156 mm² and 9,800 million transistors. It has 6 cores and 12 threads, with a base clock of 3.00 GHz and a boost clock of 3.95 GHz. The 7320C uses the smaller Mendocino die, fabricated on TSMC’s 6 nm process, with a die size of 100 mm². It has 4 cores and 8 threads, with a base clock of 2.40 GHz and a boost clock of 4.10 GHz.

Cache configurations differ substantially. The V2546 has 8 MB of shared L3 cache, while the 7320C has only 4 MB. Both have identical L1 (64 KB per core) and L2 (512 KB per core) caches. The higher boost clock of the 7320C (4.10 GHz vs 3.95 GHz) partially compensates for its smaller cache and fewer cores in single-threaded tasks.

Memory support is a key differentiator. The V2546 supports DDR4 memory with a bandwidth of 51.2 GB/s and ECC memory, while the 7320C supports LPDDR5 with a higher bandwidth of 88.0 GB/s but no ECC. This explains the 7320C’s wins in memory-sensitive benchmarks like data compression and random string sorting. The PCIe configuration also differs: the V2546 has 20 PCIe Gen 3 lanes, while the 7320C has only 4.

The TDPs reflect their intended markets: the V2546 is a 35 W desktop part, while the 7320C is a 15 W mobile part. The V2546 uses AMD Socket FP6, while the 7320C uses AMD Socket FT6. The integrated graphics differ as well: the V2546 has Radeon Graphics with 384 SP, while the 7320C has Radeon 610M. The V2546 was released in November 2020, while the 7320C arrived in May 2023.

Head-to-Head Benchmarks

The V2546’s multi-core dominance is consistent across all Cinebench versions. In R15 multi-core, it scores 827 versus 708, a 16.8% lead. R20 multi-core shows 3446 versus 2950, also 16.8%. R23 multi-core gives 8207 versus 7025, again 16.8%. Single-core Cinebench results follow the same pattern: R15 single-core is 116 vs 99 (17.2% lead), R20 single-core is 486 vs 416 (16.8%), and R23 single-core is 1158 vs 991 (16.9%). These results indicate that the V2546’s extra cores and threads translate directly into a 16-17% performance advantage across the board in render workloads.

The 7320C’s PassMark single-thread score of 2439 is its most dramatic win, beating the V2546’s 1609 by 34%. This is despite the V2546 winning the Cinebench single-core tests. The discrepancy suggests that PassMark’s single-thread test leverages the 7320C’s higher boost clock and faster LPDDR5 memory more effectively. In data compression, the 7320C scores 144465 vs 136097, a 5.8% win, likely due to memory bandwidth. Its physics score of 500 vs 441 (11.8% lead) and random string sorting of 16973 vs 13926 (18% lead) further confirm its memory-bandwidth edge.

The V2546’s largest victory is in extended instructions, scoring 8799 versus 3663 — a 140.2% margin. This is followed by data encryption, where it leads 8046 vs 5443 (47.8%). Floating-point math shows a 31.7% lead (18534 vs 14071), and prime numbers a 22.2% lead (22 vs 18). The V2546 also wins PassMark multithread with 9656 vs 8265 (16.8%). These results demonstrate that the V2546’s larger core count and L3 cache are decisive in compute-heavy, multi-threaded tasks.

The Verdict

The data points to a clear split based on workload priorities. The AMD Ryzen Embedded V2546 is the better choice for multi-threaded compute tasks, rendering, and encryption-heavy workloads. Its 16.8% lead across Cinebench multi-core tests and 47.8% lead in encryption make it the superior processor for any application that can use more than four cores. The 140.2% advantage in extended instructions further cements its position for scientific and engineering workloads.

The AMD Ryzen 3 7320C is the pick for single-threaded responsiveness and memory-bandwidth-sensitive tasks. Its 34% lead in PassMark single-thread and 18% lead in random string sorting indicate it handles interactive workloads and data shuffling more efficiently. The higher memory bandwidth of 88.0 GB/s versus 51.2 GB/s gives it a real advantage in compression (5.8% lead) and physics (11.8% lead).

For a desktop or embedded system where sustained multi-core performance and ECC memory are required, the V2546 is the clear winner. For a power-efficient mobile design where single-thread speed and memory throughput matter more, the 7320C is the better fit. The 0.4% overall average score difference means neither chip is universally better — the correct choice depends entirely on the target workload.
