AMD EPYC 7702P vs AMD Ryzen Embedded V2546 Comparison

The AMD EPYC 7702P and the AMD Ryzen Embedded V2546 both use the Zen 2 architecture, but they are built for entirely different corners of the market. The EPYC 7702P is a 64-core server monster on the SP3 platform, while the V2546 is a 6-core embedded part on the FP6 socket. The benchmark data shows a complete sweep in raw compute for the EPYC, but the V2546 brings integrated graphics and a far lower power envelope to the table. The choice between them depends entirely on whether the workload is massive parallel throughput or dense, low-power system integration.

Where Each One Wins

The recorded benchmark results show the AMD EPYC 7702P winning all six head-to-head Cinebench tests. This is not a close contest by any measure. The EPYC dominates in multi-core rendering, where its 64 cores and 128 threads overwhelm the V2546's 6 cores and 12 threads. In Cinebench R23 multi-core, the EPYC scores 52308 against the V2546's 8207, a 537.4% advantage. The same pattern holds across every Cinebench iteration, with deltas consistently around 537% to 538%. If the task is CPU-bound rendering, compilation, or any workload that scales with core count, the EPYC 7702P is the only viable option in this comparison.

The Ryzen Embedded V2546 does not win a single benchmark in the head-to-head table. However, the database shows its value in areas that the EPYC cannot address at all. The V2546 includes Radeon Graphics with 384 shader processors, while the EPYC has no integrated graphics listed. For a system that needs display output without a discrete GPU, the V2546 is the functional choice. Additionally, the V2546 has a TDP of 35 watts against the EPYC's 200 watts. This points to use cases in fanless or passively cooled embedded systems, kiosks, or industrial PCs where power draw and heat dissipation are the primary constraints. The EPYC wins every compute metric, but the V2546 wins the platform integration battle.

Architecture Differences

Both processors are built on TSMC's 7 nm process, but the similarities end there. The EPYC 7702P uses the Zen 2 architecture with the codename Rome, part of the EPYC 7002 series. It fits into AMD Socket SP3 and targets the Server/Workstation market segment. The V2546 also uses Zen 2, but with the Renoir codename, and belongs to the Ryzen Embedded 2000 series. It uses AMD Socket FP6 and is classified as a Desktop market segment part, despite its embedded positioning.

The core configurations are drastically different. The EPYC has 64 cores and 128 threads, while the V2546 has 6 cores and 12 threads. Clock speeds favor the V2546: it runs a base clock of 3.00 GHz and boosts to 3.95 GHz, whereas the EPYC has a base of 2.00 GHz and a boost of 3.35 GHz. The EPYC compensates with a massive 256 MB shared L3 cache, while the V2546 has just 8 MB shared L3. Per-core L1 cache also differs: the EPYC has 96 KB per core, the V2546 has 64 KB per core. Both share 512 KB L2 per core.

The memory subsystems are another major split. The EPYC uses eight-channel DDR4 memory with a bandwidth of 204.8 GB/s. The V2546 uses dual-channel DDR4 with 51.2 GB/s. Both support ECC memory. PCIe connectivity also differs: the EPYC supports Gen 4, while the V2546 is limited to Gen 3 with 20 lanes from the CPU. The transistor counts and die sizes tell a strange story: the V2546 has 9,800 million transistors on a 156 mm² die, while the EPYC has 3,800 million transistors on a 74 mm² die. This reflects the different packaging and chiplet strategies of the two parts.

The integrated graphics situation is a defining difference. The V2546 includes Radeon Graphics with 384 shader processors. The EPYC has no integrated graphics listed. For any system that needs onboard display capabilities, the V2546 is the only one of the two that can deliver it without an additional GPU.

Specification Differences

The two processors differ on nearly every major specification. The EPYC 7702P uses 64 cores and 128 threads, while the V2546 uses 6 cores and 12 threads. Base clock speeds are 2.00 GHz for the EPYC and 3.00 GHz for the V2546. Boost clocks are 3.35 GHz and 3.95 GHz respectively. TDP is a major gap: 200 watts for the EPYC versus 35 watts for the V2546.

The sockets are incompatible: the EPYC uses AMD Socket SP3, the V2546 uses AMD Socket FP6. The EPYC is in the EPYC 7002 series with the Rome codename, while the V2546 is in the Ryzen Embedded 2000 series with the Renoir codename. Process node is identical at 7 nm from TSMC, but transistor counts differ: 3,800 million for the EPYC versus 9,800 million for the V2546. Die sizes are 74 mm² for the EPYC and 156 mm² for the V2546.

Cache configurations are very different. The EPYC has 96 KB of L1 per core, 512 KB of L2 per core, and 256 MB of shared L3. The V2546 has 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. Memory support is DDR4 for both, but the EPYC uses eight channels with 204.8 GB/s bandwidth, while the V2546 uses dual channels with 51.2 GB/s.

PCIe support differs: the EPYC has Gen 4, the V2546 has Gen 3 with 20 lanes from the CPU. Integrated graphics are present only on the V2546, with Radeon Graphics at 384 shader processors. The EPYC has no integrated graphics. The market segments also differ: the EPYC is for Server/Workstation, the V2546 for Desktop. The release dates are about 15 months apart, with the EPYC released in August 2019 and the V2546 in November 2020.

Head-to-Head Benchmarks

The head-to-head results are one-sided. In Cinebench R15 multi-core, the EPYC scores 5272 against 827, a 537.5% delta. In R15 single-core, the EPYC scores 744 against 116, a 541.4% delta. The single-core margin is actually larger in percentage terms, which is notable because the V2546 has a higher boost clock at 3.95 GHz. The EPYC's 3.35 GHz boost still wins the single-threaded tests, likely due to the massive cache and memory bandwidth advantages.

Cinebench R20 follows the same pattern. Multi-core shows the EPYC at 21969 versus 3446, a 537.5% delta. Single-core shows 3101 versus 486, a 538.1% delta. Cinebench R23 repeats the story: multi-core is 52308 versus 8207, a 537.4% delta, and single-core is 7384 versus 1158, a 537.7% delta. The deltas are remarkably consistent, hovering around 537% to 538% for multi-core and reaching up to 541.4% for R15 single-core. This consistency suggests the EPYC's advantage scales uniformly across different Cinebench versions.

The average benchmark scores reflect the overall gap. The EPYC has an average benchmark score of 15130, while the V2546 has 14336. Both sit at the 69th percentile among all CPUs, which shows that the V2546 is not a weak performer in the broader market, it just faces an overwhelming opponent here. The EPYC's nearest rivals include the Intel Core i3-1315U with a 0.7% delta and the AMD EPYC 74F3 with a 1.4% delta. The V2546's nearest rivals include the AMD Ryzen 5 3501U at a 0.1% delta and the Intel Core i5-10400F at a 1.1% delta.

The Verdict

The AMD EPYC 7702P is the clear choice for raw compute. It wins every benchmark in the comparison by a margin of over 537%. If the workload is multi-core rendering, virtualization, database processing, or any server-class task that can use 64 cores and 128 threads, the EPYC is the only rational selection. Its eight-channel memory with 204.8 GB/s bandwidth and 256 MB of L3 cache make it a platform built for sustained heavy throughput. The 200 watt TDP and SP3 socket are appropriate for a server chassis with robust cooling.

The AMD Ryzen Embedded V2546 is the choice for a completely different set of requirements. Its 35 watt TDP makes it viable for systems where power and heat are the limiting factors. The integrated Radeon Graphics with 384 shader processors means it can drive displays without a discrete GPU, something the EPYC cannot do. Its dual-channel memory and Gen 3 PCIe are modest, but sufficient for embedded workloads like industrial control, digital signage, or edge computing. The higher base and boost clocks, 3.00 GHz and 3.95 GHz, also help in lightly threaded tasks where the EPYC's lower clocks and massive core count are not needed.

The data does not suggest any scenario where the V2546 outperforms the EPYC in CPU benchmarks. The EPYC wins even single-core tests by more than 500%. The V2546 wins only on platform attributes: integrated graphics, lower TDP, and a smaller physical footprint with the FP6 socket. For a builder choosing between these two, the decision is not about which CPU is faster, it is about which platform fits the application. Server racks and high-throughput workstations point to the EPYC. Compact, power-conscious embedded devices with display output point to the V2546.
