AMD EPYC 7443 vs AMD Ryzen Embedded V2546 Comparison

The recorded data delivers an unusually one-sided verdict: the AMD EPYC 7443 wins every single head-to-head benchmark against the AMD Ryzen Embedded V2546, taking all six recorded Cinebench comparisons by a margin of roughly 83 percent. What makes this matchup interesting is not the outcome but the context: the V2546 is a 35 W embedded part built for efficiency, while the 7443 is a 200 W server processor, and the two land in nearly the same percentile of the database (69 versus 68) because their aggregate profiles draw from very different workloads. Both remain in active production, and each occupies a legitimate niche that the raw head-to-head numbers do not fully capture.

Head-to-Head Benchmarks

Every direct comparison in the database favors the EPYC 7443, and by an almost identical margin each time. In Cinebench R15 multi-core the EPYC scores 4856 against the V2546's 827, an 83 percent gap. The single-core result is nearly the same story: 685 versus 116, an 83.1 percent delta. That consistency across both threaded and lightly threaded tests is remarkable, because multi-core margins usually dwarf single-core margins when one chip has far more cores. Here it does not, and the reason is architectural.

Cinebench R20 repeats the pattern. The EPYC posts 20236 multi-core points to the V2546's 3446, again an 83 percent difference, and single-core lands at 2856 versus 486, also 83 percent. Cinebench R23 closes the set: 48183 versus 8207 multi-core and 6802 versus 1158 single-core, both deltas at 83 percent.

The near-perfect symmetry of these numbers tells you two things. First, the EPYC's Zen 3 architecture is decisively stronger per clock and per thread than the V2546's Zen 2, since a 24-core-versus-6-core count would otherwise produce a much larger multi-core gap than a single-core one. Second, the V2546's 3.00 GHz base and 3.95 GHz boost clocks cannot compensate for the older core design against a chip that boosts almost as high, at 4.00 GHz, with four times the cores and twice the threads.

The PassMark suite gives a fuller picture of the V2546 in isolation, since the database holds no matching EPYC 7443 results there. The V2546 records 9656 in PassMark multithread, 1609 in single thread, 30739 in integer math, 18534 in floating point math, 8046 in data encryption, 136097 in data compression, 13926 in string sorting, 8799 in extended instructions, and 441 in physics. Those figures place it in the 69th percentile against all CPUs in the database, essentially tied with its nearest rivals: the Ryzen 5 3501U sits 0.1 percent away, the Ryzen 3 7320C 0.4 percent, the Intel Core 7 160UL 0.7 percent, and the Core i5-10400F 1.1 percent. The EPYC's own rival cluster is similarly tight, with the Core i7-8750H 0.5 percent away, the Core i5-10400 at minus 0.7 percent, the Threadripper PRO 3975WX at 1.1 percent, and the EPYC 7552 at minus 1.3 percent.

Architecture Differences

Both processors come from AMD and both are fabbed on TSMC's 7 nm process, but almost everything else diverges. The V2546 uses the Zen 2 architecture under the Renoir codename, while the 7443 uses Zen 3 under the Milan codename. That generational leap is the single biggest factor in the uniform 83 percent benchmark gaps, because Zen 3 brought substantially higher instructions-per-clock than Zen 2.

Core counts differ by a factor of four: 6 cores and 12 threads for the V2546 versus 24 cores and 48 threads for the 7443. Cache scales accordingly. Per-core L1 and L2 are identical on paper, 64 KB and 512 KB respectively, but the shared L3 pool separates the two completely: 8 MB on the V2546 against 128 MB on the 7443, a sixteen-fold difference that matters enormously for datacenter workloads with large working sets. The EPYC's die configuration reflects that scale, four chiplets of 81 mm² each with 16,600 million transistors in total, versus the V2546's single 156 mm² die with 9,800 million transistors.

Memory and I/O follow the same split. The V2546 supports dual-channel DDR4 with 51.2 GB/s of bandwidth, while the 7443 runs eight-channel DDR4 at 204.8 GB/s, four times the throughput. Both support ECC memory, which is expected given their embedded and server markets. PCIe differs sharply: the V2546 offers Gen 3 with 20 CPU lanes, the 7443 Gen 4 with 128 CPU lanes, a difference that defines what each chip can host in terms of storage, networking, and accelerators.

The sockets are incompatible by design. The V2546 uses AMD Socket FP6, the 7443 AMD Socket SP3, so there is no platform overlap. The V2546 also carries integrated graphics, Radeon Graphics with 384 shader processors, which the EPYC entirely lacks; any 7443 system needs discrete graphics for display output. Their TDPs of 35 W and 200 W respectively frame the entire comparison: one is built for constrained thermal envelopes, the other for throughput.

Release timing differs too. The V2546 appeared on November 9, 2020, and the 7443 followed on March 14, 2021, so the EPYC also benefits from being the newer design. The 7443's launch MSRP was $2010. Neither part has an unlocked multiplier.

Where Each One Wins

On raw benchmark wins, the EPYC 7443 wins everywhere the two directly overlap: all six Cinebench tests, multi-core and single-core alike, by roughly 83 percent margins. Its 24 cores, 48 threads, 128 MB of L3, and 204.8 GB/s memory subsystem make it the clear choice for sustained throughput work: rendering, virtualization, dense compute, and anything that scales with threads and memory bandwidth. Its 128 Gen 4 PCIe lanes enable expansion-heavy configurations the V2546 simply cannot match.

The V2546's wins are structural rather than scoreboard-based. Its 35 W TDP is the headline: at roughly a sixth of the EPYC's 200 W power rating, it delivers a percentile ranking of 69, one point higher than the EPYC's 68. Per watt of cooling and power delivery, it is in an entirely different class. Its integrated Radeon Graphics 384SP removes the need for a discrete GPU, its FP6 socket suits compact embedded systems, and its PassMark single-thread score of 1609, with integer math at 30739 and floating point at 18534, shows it handles general-purpose and lightly threaded embedded workloads competently. It clusters with efficient mobile-class parts like the Ryzen 5 3501U and the Core 7 160UL, which tells you exactly what its performance envelope is.

The Verdict

The data shows two processors serving unrelated missions. If the workload is measured in throughput, render frames, virtual machines, or database transactions, the EPYC 7443 is the only rational pick of the pair: it wins every shared benchmark by about 83 percent, single-core included, and pairs that with vastly more cache, memory bandwidth, and PCIe connectivity. If the workload is size-, power-, or thermally-constrained, the V2546 is the pick: a 35 W Zen 2 part with integrated graphics, ECC support, and database standing in the 69th percentile. The V2546 should not be judged against the 7443 at all, because its rival set, with deltas under 1.1 percent against parts like the Ryzen 5 3501U and Core i5-10400F, places it squarely in the efficient mainstream, not the server arena.
