AMD EPYC 7232P vs Intel Core i7-9800X Comparison

The Intel Core i7-9800X and AMD EPYC 7232P are both 8-core, 16-thread processors, yet they target fundamentally different platforms. The benchmark data reveals a consistent, though narrow, performance advantage for the Intel part across every tested workload, while the EPYC counters with architectural and platform-level features. This analysis breaks down the implications of those results.

Head-to-Head Benchmarks

The head-to-head results are remarkably uniform. The Intel Core i7-9800X wins all six benchmark comparisons, but the margin of victory is consistently narrow, hovering just over two percent. In Cinebench R15 multi-core, the i7-9800X scores 1553 against the EPYC 7232P's 1517, a 2.4% lead. The single-core test in the same suite shows a similar story: 219 versus 214, a 2.3% advantage. This pattern holds across the newer Cinebench versions as well. In R20 multi-core, the Intel part scores 6474 versus 6323 for the EPYC, again a 2.4% edge. The R20 single-core test shows 913 versus 892, also a 2.4% delta.

The trend continues into Cinebench R23. The i7-9800X posts a multi-core score of 15416, while the EPYC 7232P manages 15055, a 2.4% difference. The R23 single-core results are 2176 against 2125, once more a 2.4% gap. The consistency of the deltaPct across different workloads is notable; it suggests the performance difference is not tied to scaling or thread management, but rather to a fundamental per-core throughput advantage for the Intel design. The data shows the i7-9800X holds a 2.4% lead in the majority of tests, which translates to a definitive, if small, win in every category.

The Geekbench scores reinforce this positioning, though they are not part of the head-to-head set. The i7-9800X scores 7488 in multi-core and 1398 in single-core, while the EPYC 7232P has no Geekbench results listed. This absence of data for the EPYC in one benchmark suite is itself a notable gap in the comparative picture.

FAQ

Q: Which processor has a higher average benchmark score?

A: The Intel Core i7-9800X has an average benchmark score of 4455, which is 101 points higher than the AMD EPYC 7232P's average of 4354. Both processors sit at the 58th percentile when compared to all CPUs.

Q: How does the single-core performance compare between the two?

A: The Intel Core i7-9800X wins every single-core test. In Cinebench R23, it scores 2176 versus the EPYC 7232P's 2125, a 2.4% advantage. In R15, the margin is 219 to 214, a 2.3% lead.

Q: Is there a benchmark where the AMD EPYC 7232P wins?

A: No. The head-to-head data shows the Intel Core i7-9800X wins all six comparison benchmarks, with the AMD EPYC 7232P recording zero wins. The closest the EPYC gets is the 2.3% delta in Cinebench R15 single-core.

Q: What is the difference in memory channel support?

A: The AMD EPYC 7232P supports eight-channel memory, while the Intel Core i7-9800X supports quad-channel memory. Despite this, both list the same memory bandwidth of 85.3 GB/s.

Q: Do these processors support ECC memory?

A: Yes, the AMD EPYC 7232P supports ECC memory, while the Intel Core i7-9800X does not. This is a significant feature difference for server and workstation reliability.

Q: What are the PCIe lane counts?

A: The AMD EPYC 7232P provides 128 PCIe Gen 4 lanes (CPU only). The Intel Core i7-9800X provides 44 PCIe Gen 3 lanes (CPU only). The EPYC offers a substantially higher lane count and a newer generation of PCIe.

The Verdict

The data points to a clear, if narrow, victory for the Intel Core i7-9800X in raw compute benchmarks. It wins every head-to-head test, with a consistent 2.4% lead in most. For tasks that rely purely on CPU rendering or single-threaded responsiveness, the i7-9800X is the better performer according to the benchmark suite. The data shows the Intel part is ahead in all Cinebench R15, R20, and R23 tests.

However, the verdict is not one-sided. The AMD EPYC 7232P's advantages lie in its platform capabilities, not its benchmark scores. It offers eight-channel memory, 128 PCIe Gen 4 lanes, and ECC memory support, features that are absent from the Intel part. The EPYC also has a lower TDP of 120 watts compared to the i7-9800X's 165 watts. The choice depends on whether raw benchmark scores or platform features are more important for the intended use case. The Intel part wins on compute, the AMD part wins on platform capability.

Specification Differences

The two processors differ in several key specifications. The Intel Core i7-9800X has a base clock of 3.80 GHz and a boost clock of 4.50 GHz, while the AMD EPYC 7232P has a base clock of 3.10 GHz and a boost clock of 3.20 GHz. The Intel part has a TDP of 165 watts, the EPYC a TDP of 120 watts. They use different sockets: Intel Socket 2066 for the i7-9800X and AMD Socket SP3 for the EPYC.

Their cache configurations also differ. The Intel part has 1 MB of L2 cache per core and 16.5 MB of shared L3 cache. The AMD EPYC has 512 KB of L2 cache per core and 16 MB of L3 cache per die, totaling 32 MB. The memory support differs in channels: the Intel part uses quad-channel memory, while the EPYC uses eight-channel memory, though both list a bandwidth of 85.3 GB/s. The Intel part does not support ECC memory, while the EPYC does. PCIe support is also different: the i7-9800X has 44 Gen 3 lanes, while the EPYC has 128 Gen 4 lanes. The Intel part has an unlocked multiplier, whereas the EPYC is locked. The Intel part is end-of-life, while the EPYC is an active product.

Architecture Differences

The processors are built on fundamentally different architectures. The Intel Core i7-9800X uses the Skylake-X architecture on a 14 nm process node, manufactured by Intel. It is part of the Core i7 X-Series 9th Generation. The AMD EPYC 7232P uses the Zen 2 architecture, codenamed Rome, on a 7 nm process node manufactured by TSMC. It belongs to the EPYC 7002 series.

The EPYC's 7 nm process is a generation ahead of Intel's 14 nm node, which is reflected in its smaller die size: the EPYC uses 2x 74 mm² dies with 7,600 million transistors. The Intel part's transistor count and die size are not listed. The EPYC's architecture is designed for server workloads, indicated by its eight-channel memory controller and 128 PCIe lanes. The Intel part, while also a high-core-count desktop processor, uses a quad-channel memory controller and more limited PCIe lanes. The EPYC also has a larger total L3 cache at 32 MB versus the Intel's 16.5 MB.

Where Each One Wins

Intel Core i7-9800X: The data shows this processor wins in every single benchmark test. It is the faster part for Cinebench R15, R20, and R23 workloads, both multi-core and single-core. Its higher boost clock of 4.50 GHz likely contributes to its 2.4% lead in single-threaded tasks. For users who need the absolute maximum performance in applications that are heavily threaded or rely on high single-thread speeds, the i7-9800X is the winner according to the data. Its unlocked multiplier also allows for overclocking, which could widen the performance gap.

AMD EPYC 7232P: This processor wins in no benchmark tests, but it wins on platform features. It supports ECC memory, which is crucial for data integrity in server and workstation environments. Its eight-channel memory architecture and 128 PCIe Gen 4 lanes provide significantly more bandwidth and connectivity options than the Intel part. The EPYC's 7 nm process and 120 watt TDP suggest better power efficiency per unit of work, though no efficiency benchmarks are provided. For a server or workstation where memory capacity, I/O expandability, and error-correcting memory are more important than a 2.4% CPU performance delta, the EPYC 7232P is the stronger choice.
