AMD EPYC 7282 vs Intel Core i9-9960X Comparison

The AMD EPYC 7282 and Intel Core i9-9960X are both 16-core, 32-thread processors, but they target different segments: the EPYC is a server/workstation part, while the Core i9 is a desktop flagship. The recorded Cinebench results show a consistent, if narrow, advantage for the EPYC across all six head-to-head tests, with margins between 1.9% and 2%. This analysis examines the benchmark data, architectural differences, and use-case implications.

Head-to-Head Benchmarks

The head-to-head comparison includes six Cinebench tests, spanning R15, R20, and R23, each with single-core and multi-core variants. The AMD EPYC 7282 wins every single test. The margins are tight, but they are uniform across all versions.

In Cinebench R15 multi-core, the EPYC scores 2581 against the Intel's 2532, a 1.9% lead. The single-core R15 result is 364 versus 357, a 2% advantage. Moving to R20, the multi-core score is 10758 for the EPYC and 10550 for the Intel, again a 2% difference. The R20 single-core test shows 1518 versus 1489, a 1.9% gap. In R23, the multi-core result is 25616 against 25120, a 2% lead, and the single-core score is 3616 versus 3546, also 2% ahead.

These results are notable because the Intel part has a significantly higher boost clock: 4.50 GHz compared to the EPYC's 3.20 GHz. Despite that frequency advantage, the EPYC still edges ahead in every recorded Cinebench test. The consistency of the 2% margin suggests a fundamental efficiency difference rather than a workload-specific quirk.

The database also records Geekbench scores for the Intel Core i9-9960X, with a multi-core score of 10512 and a single-core score of 1396. However, no corresponding Geekbench results are listed for the EPYC 7282, so these are not part of the head-to-head comparison. The overall average benchmark score, which aggregates all recorded tests for each processor, stands at 7409 for the EPYC and 6938 for the Intel. This broader metric reinforces the EPYC's lead, though it includes different test sets.

Where Each One Wins

The EPYC 7282 wins all six Cinebench tests, which are standard measures of rendering and multi-threaded CPU performance. For workloads that rely on sustained multi-core execution, such as 3D rendering, video encoding, and scientific simulation, the data points clearly to the EPYC. Its single-core wins, while smaller, also indicate that it does not sacrifice single-threaded responsiveness.

The Intel Core i9-9960X, despite its higher boost clock and unlocked multiplier, does not win any recorded Cinebench test. Its advantages lie elsewhere. The unlocked multiplier allows frequency adjustment, which can be useful for overclocking, though the recorded scores do not reflect any overclocked state. The Intel part also has a higher base clock (3.10 GHz versus 2.80 GHz), but that does not translate into benchmark wins.

For server and workstation use, the EPYC offers features that the Intel part lacks. It supports ECC memory, which is critical for data integrity in long-running computations. It has an eight-channel memory bus, compared to the Intel's quad-channel, though both are rated at the same memory bandwidth of 85.3 GB/s. The EPYC also provides PCIe Gen 4 with 128 lanes, while the Intel has PCIe Gen 3 with 44 lanes. This makes the EPYC far more suitable for high-throughput I/O, such as NVMe storage arrays, GPUs, and network adapters.

The Intel part is a desktop processor, and its platform (Socket 2066) is designed for enthusiast builds. It has a lower TDP of 165W compared to the EPYC's 120W, but that is a power consumption figure, not a performance metric. The Intel part is also end-of-life, while the EPYC remains active in production.

Architecture Differences

The two processors are built on fundamentally different architectures. The EPYC 7282 uses AMD's Zen 2 architecture, codenamed Rome, fabricated on a 7 nm process at TSMC. The Intel Core i9-9960X uses the Skylake architecture, codenamed Skylake-X, on Intel's 14 nm process. This process difference is significant: the EPYC's 7 nm node allows for higher transistor density and lower power consumption.

The die size reflects this. The EPYC has two dies, each measuring 74 mm², for a total of 148 mm². The Intel part has a single die of 484 mm². The EPYC contains 7,600 million transistors, while the Intel's transistor count is not listed in the database.

Cache hierarchies also differ. Both have 64 KB of L1 cache per core. The EPYC has 512 KB of L2 per core, while the Intel has 1 MB per core. The L3 cache is more divergent: the EPYC has 32 MB per die, totaling 64 MB, while the Intel has 22 MB shared across all cores. The EPYC's larger L3 cache can improve performance in workloads with large working sets.

Memory support is another differentiator. Both support DDR4, but the EPYC uses an eight-channel memory bus, while the Intel uses quad-channel. Despite this, both are rated at the same memory bandwidth of 85.3 GB/s. The EPYC supports ECC memory, the Intel does not. The EPYC provides PCIe Gen 4 with 128 lanes, the Intel provides PCIe Gen 3 with 44 lanes.

The sockets are incompatible: the EPYC uses AMD Socket SP3, the Intel uses Socket 2066. The EPYC has a TDP of 120W, the Intel 165W. The EPYC's multiplier is locked, while the Intel's is unlocked. The EPYC was released on 2019-08-06, the Intel on 2018-10-18. The launch MSRP for the EPYC is $650, and for the Intel it is $1684.

The Verdict

The benchmark data is unambiguous: the AMD EPYC 7282 outperforms the Intel Core i9-9960X in every recorded Cinebench test, with margins of 1.9% to 2%. The EPYC also offers a more modern architecture, a smaller process node, more L3 cache, eight-channel memory, ECC support, and a far larger PCIe lane count. It has a lower TDP and a lower launch MSRP. The Intel part's only advantages are a higher boost clock, an unlocked multiplier, and a desktop-oriented platform.

For server, workstation, and data-center workloads, the EPYC is the clear choice. Its combination of multi-threaded performance, memory bandwidth, ECC, and PCIe Gen 4 connectivity makes it suitable for virtualization, database serving, and high-performance computing. The Intel part, with its unlocked multiplier, may appeal to enthusiasts who plan to overclock, but the recorded scores do not show any performance benefit from that capability. Given that the Intel part is end-of-life and the EPYC is active, the EPYC also offers a longer support horizon.

Both processors share the same 63rd percentile ranking among all CPUs, but the EPYC's higher average benchmark score (7409 versus 6938) and its clean sweep in head-to-head tests indicate that it is the stronger performer. The verdict is straightforward: the EPYC 7282 is the better processor for anyone who prioritizes measured performance and platform features.
