AMD EPYC 7282 vs AMD EPYC 7551P Comparison

AMD EPYC 7282 and AMD EPYC 7551P are both server/workstation processors on the AMD Socket SP3 platform, but they represent two distinct generations of AMD's EPYC lineup. The 7282 comes from the 7002 series (Zen 2, Rome), while the 7551P belongs to the 7001 series (Zen, Naples). The recorded benchmarks show a clear overall winner in the 7551P, which takes all six head-to-head tests, but the architectural differences between the two chips explain why the performance gap exists and where each part still has a role.

Where Each One Wins

The data is unambiguous: the AMD EPYC 7551P wins every single benchmark recorded in the database. Across Cinebench R15, R20, and R23, both in single-core and multi-core tests, the 7551P outpaces the 7282 by a consistent 21.2%. That means the 7551P is not just faster in one workload type, it is uniformly ahead in every rendering and compute scenario captured by these tests.

For the EPYC 7282, there are no benchmark wins to point to. Its advantage is not in raw performance but in efficiency and platform modernity. The 7282 draws 120W TDP versus 180W for the 7551P, and it runs on the newer 7 nm process from TSMC. It also supports PCIe Gen 4 with 128 lanes from the CPU, while the 7551P is limited to PCIe Gen 3. In a dense server environment where per-core power and I/O bandwidth matter more than raw multi-threaded throughput, the 7282 is the more modern foundation. But if the workload is purely about Cinebench scores, the 7551P is the clear choice.

Architecture Differences

These two processors come from different generations of AMD's EPYC roadmap. The 7282 is built on Zen 2 architecture, codenamed Rome, and manufactured on a 7 nm process at TSMC. The 7551P uses the original Zen architecture, codenamed Naples, on a 14 nm process at GlobalFoundries. That process gap is significant: the 7282 packs 7,600 million transistors into two 74 mm² dies, while the 7551P has 4,800 million transistors on a single 213 mm² die.

Core counts differ sharply. The 7282 has 16 cores and 32 threads, while the 7551P doubles that to 32 cores and 64 threads. Cache layouts also diverge. The 7282 has 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 per die, for a total of 64 MB across two dies. The 7551P has 96 KB of L1 per core, 512 KB of L2 per core, and a shared 64 MB of L3. So the 7551P has more L1 per core and a larger unified L3, while the 7282 splits its L3 across two dies.

Clock speeds tell an interesting story. The 7282 has a base clock of 2.80 GHz and a boost of 3.20 GHz. The 7551P has a base clock of 2000.00 MHz (2.00 GHz) and a boost of 3.00 GHz. Despite the lower base clock, the 7551P still wins every benchmark, which points to the core count advantage being decisive in multi-threaded tests and the boost clock being close enough to matter less in single-threaded tests.

Memory support is similar in topology but different in bandwidth. Both use DDR4 with an eight-channel memory bus. The 7282 has a memory bandwidth of 85.3 GB/s, while the 7551P reaches 170.6 GB/s. The 7551P also has an unlocked multiplier, while the 7282 is locked. Both support ECC memory. The 7282 was released on 2019-08-06 with a launch MSRP of $650. The 7551P was released on 2017-06-28 and has no recorded launch MSRP in the database.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. In Cinebench R15 multi-core, the 7551P scores 3276 against 2581 for the 7282, a 21.2% advantage. In Cinebench R15 single-core, the 7551P scores 462 against 364, again 21.2% ahead. The same delta appears in Cinebench R20: multi-core shows 13650 versus 10758, and single-core shows 1926 versus 1518. Cinebench R23 continues the pattern with multi-core at 32500 versus 25616 and single-core at 4588 versus 3616. Every single test shows the exact same 21.2% gap, indicating that the performance difference is largely structural, not workload-dependent.

The 7551P also has Geekbench results in the database, scoring 6296 in multi-core and 919 in single-core. The 7282 does not have Geekbench scores recorded, so no direct comparison is possible there. But the Cinebench data alone is enough to establish the 7551P as the faster part across the board.

Looking at the nearest rivals in the database, the 7282 sits at a 63rd percentile among all CPUs with an average benchmark score of 7409. Its closest competitors include the Intel Core i9-9990XE at 7415 (0.1% slower than the 7282), the Intel Core i9-9980XE at 7398 (0.2% faster), the Intel Core i5-4570 at 7421 (0.2% slower), and the Intel Core i5-7400 at 7469 (0.8% slower). These are all very close scores, meaning the 7282 is in a tight cluster of mid-range performance.

The 7551P, by contrast, sits at a 64th percentile with an average benchmark score of 7952. Its nearest rivals are the Intel Core i7-13700E at 7957 (0.1% faster), the Intel Core i9-10980XE at 7910 (0.5% slower), the Intel Xeon Gold 6326 at 8071 (1.5% faster), and the Intel Xeon Platinum 8180M at 8110 (1.9% faster). The 7551P is slightly ahead of the 7282 in percentile terms, but its nearest rivals are generally more powerful, which reflects its higher absolute scores.

The Verdict

The data is one-sided. The AMD EPYC 7551P wins all six recorded head-to-head benchmarks, with a consistent 21.2% margin over the EPYC 7282 in both single-core and multi-core Cinebench tests. Anyone choosing between these two strictly on measured performance should pick the 7551P. It also offers double the cores, double the memory bandwidth, and a higher average benchmark score of 7952 versus 7409.

The EPYC 7282 has its own merits, but they are not reflected in Cinebench scores. It runs on a newer 7 nm process, which explains its lower 120W TDP versus 180W, and it brings PCIe Gen 4 support to the table. For workloads that are heavily I/O bound, or where power per socket is a constraint, the 7282 is the more efficient and modern part. Its 64 MB of total L3 cache is identical in size to the 7551P's shared 64 MB, but the 7282 splits it across two dies.

For raw compute throughput, the verdict is clear: the EPYC 7551P is the faster processor. For platform longevity and efficiency, the EPYC 7282 is the more forward-looking choice. The database shows the 7551P as the winner in every measured test, so the recommendation for performance-first builds is straightforward. The 7282 remains relevant for those who prioritize the newer process node, lower power draw, and PCIe Gen 4 connectivity over raw Cinebench results.
