AMD EPYC 7252 vs AMD Ryzen Embedded V2748 Comparison

FAQ

Q: Which processor is faster in multi-threaded workloads?

A: The AMD EPYC 7252 wins every recorded multi-core benchmark. It scores 1662 in Cinebench R15, 6929 in R20, and 16499 in R23, compared to the Ryzen Embedded V2748's 1579, 6580, and 15668 respectively. The EPYC leads by exactly 5% in each multi-core test.

Q: Does the Ryzen Embedded V2748 win any single-core test?

A: No. The EPYC 7252 also wins all three single-core tests. It scores 234, 978, and 2329 in Cinebench R15, R20, and R23 single-core, while the V2748 scores 222, 929, and 2212. The single-core deltas are 5.1%, 5%, and 5% respectively.

A: The EPYC 7252 has a launch MSRP of $475. The Ryzen Embedded V2748 has no recorded launch MSRP in the database.

Architecture Differences

Both processors share the Zen 2 architecture and are fabricated by TSMC on a 7 nm process node, but their implementations diverge significantly. The Ryzen Embedded V2748 uses the Renoir codename and is built for the AMD Socket FP6, targeting the desktop embedded market. The EPYC 7252 uses the Rome codename and fits into the AMD Socket SP3, designed for server and workstation platforms.

The transistor budgets differ notably. The V2748 packs 9,800 million transistors on a 156 mm² die, while the EPYC 7252 uses 7,600 million transistors split across two dies, each measuring 74 mm². This dual-die arrangement for the EPYC likely contributes to its different cache hierarchy and memory subsystem.

Cache configurations are a major architectural differentiator. Both have 64 KB of L1 cache per core and 512 KB of L2 per core. However, the L3 cache differs substantially: the V2748 has 8 MB shared, while the EPYC 7252 has 32 MB per die, totaling 64 MB. That is an 8x difference in total L3 capacity, which directly impacts how much working set can reside on-chip.

The memory controllers also differ at the architectural level. The V2748 integrates a dual-channel DDR4 controller, while the EPYC 7252 integrates an eight-channel controller. This is not just a spec sheet difference; it changes the entire memory topology and achievable bandwidth for multi-socket or memory-heavy server deployments.

Another key architectural split is the PCIe implementation. The V2748 provides Gen 3 with 20 lanes, while the EPYC 7252 provides Gen 4 with 128 lanes. The EPYC's PCIe Gen 4 support doubles the per-lane bandwidth available on the V2748, and the lane count difference enables far more expansion devices.

The V2748 includes integrated Radeon Graphics with 448 shader processors, while the EPYC 7252 has no integrated graphics. This means the V2748 can drive displays without a discrete GPU, whereas the EPYC requires a separate graphics solution.

Clock behavior also differs. The V2748 has a base clock of 2.90 GHz and boosts to 4.25 GHz, while the EPYC 7252 has a higher base clock of 3.10 GHz but boosts only to 3.20 GHz. The V2748 has a much larger boost headroom, indicating different power and thermal design targets.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the EPYC 7252 wins all six recorded Cinebench tests. In every case, the delta is tightly clustered around 5%, which suggests the EPYC's advantage is consistent across both single-thread and multi-thread workloads.

Starting with multi-core, the Cinebench R15 result shows the EPYC at 1662 versus the V2748 at 1579, a 5% deficit for the V2748. In R20 multi-core, the EPYC scores 6929 against 6580, again a 5% gap. In R23 multi-core, the EPYC reaches 16499 while the V2748 manages 15668, maintaining the same 5% margin. This consistency indicates that the EPYC's advantage scales with thread count without diminishing.

Single-core results follow the same pattern. In Cinebench R15 single-core, the EPYC scores 234 versus 222, a 5.1% lead. In R20 single-core, the EPYC scores 978 versus 929, a 5% lead. In R23 single-core, the EPYC scores 2329 versus 2212, another 5% lead. The near-identical deltas across all tests suggest that per-core IPC and clock behavior are closely matched, with the EPYC's slightly higher base clock (3.10 GHz versus 2.90 GHz) providing a small but consistent edge.

The V2748's higher boost clock of 4.25 GHz does not translate into a single-core win. This is notable because boost clocks typically favor single-thread performance. The data shows the EPYC's 3.20 GHz boost clock still delivers better single-core results, likely due to the EPYC's larger L3 cache and more robust memory subsystem.

The average benchmark score places the EPYC 7252 at 4772, compared to 4532 for the V2748. The EPYC also holds a marginally higher percentile rank at 59 versus 58. These aggregate figures reinforce the head-to-head results: the EPYC is consistently ahead, but by a modest margin rather than a dramatic one.

The TDP difference is stark: 35 W for the V2748 versus 120 W for the EPYC. This makes the V2748 far more power-efficient per watt, though the EPYC's higher power budget enables its larger memory and PCIe infrastructure. The release dates also differ, with the V2748 arriving over a year after the EPYC.

Where Each One Wins

The EPYC 7252 wins every benchmark in the database, so its strengths are clear across all Cinebench workloads. It delivers a consistent 5% advantage in both single-core and multi-core tests. The EPYC also dominates in memory bandwidth with 85.3 GB/s versus 51.2 GB/s, and it offers PCIe Gen 4 with 128 lanes compared to Gen 3 with 20 lanes. For server workloads that require high memory throughput, large L3 cache, or extensive I/O expansion, the EPYC is the clear choice.

The Ryzen Embedded V2748 wins on power efficiency. Its 35 W TDP is dramatically lower than the EPYC's 120 W, making it suitable for thermally constrained or always-on embedded systems. The V2748 also includes integrated Radeon Graphics, which eliminates the need for a separate GPU in display-capable systems. Its smaller die size and lower transistor count might also indicate simpler integration requirements.

The V2748's higher boost clock of 4.25 GHz versus 3.20 GHz does not yield a benchmark win, but it does suggest that the V2748 has more burst potential in short, lightly threaded tasks that do not appear in the Cinebench results. The V2748's dual-channel memory bus and 20 PCIe lanes are sufficient for many embedded applications that do not need massive I/O.

For raw compute performance, the EPYC 7252 is superior in every measured metric. For power-sensitive embedded deployments with graphics needs, the V2748 offers a compelling feature set despite losing all benchmarks.

The Verdict

The benchmark data is decisive: the AMD EPYC 7252 outperforms the AMD Ryzen Embedded V2748 in all six Cinebench tests, with deltas between 5% and 5.1%. If the selection criterion is maximum compute performance, the EPYC 7252 is the correct pick. Its higher average benchmark score of 4772 versus 4532, combined with its 59th percentile ranking versus 58th, confirms a small but real performance advantage.

The EPYC 7252 also wins decisively on platform capabilities. Its eight-channel memory bus with 85.3 GB/s bandwidth, 64 MB of total L3 cache, and 128 PCIe Gen 4 lanes make it the superior foundation for memory-intensive and I/O-heavy server workloads. The EPYC's launch MSRP of $475 provides a reference point for its positioning.

The Ryzen Embedded V2748 is the better choice for embedded systems where power consumption and thermal output are primary constraints. Its 35 W TDP versus 120 W makes it far easier to cool and power. The integrated Radeon Graphics with 448 shader processors adds display functionality that the EPYC completely lacks. For fanless industrial PCs, edge gateways, or compact appliances, the V2748's feature set aligns better with those use cases.

In direct performance terms, the EPYC 7252 wins every benchmark, so users seeking raw Cinebench scores should choose the EPYC. However, the V2748's power efficiency and integrated graphics mean it is not without merit. The verdict from the data: the EPYC 7252 for performance and server features, the V2748 for power-constrained embedded deployments with graphics requirements.
