AMD EPYC 7232P vs Intel Core i9-9900 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the AMD EPYC 7232P wins every single head-to-head comparison against the Intel Core i9-9900. Across six Cinebench tests, the EPYC 7232P leads by a consistent margin of 11.4% to 11.5%. This is not a narrow victory in select workloads; it is a sweeping sweep across both multi-core and single-core performance.

In Cinebench R15 multi-core, the EPYC 7232P scores 1517 against 1361 for the Core i9-9900, a delta of 11.5%. The single-core R15 result shows the same 11.5% gap, with 214 versus 192. Moving to Cinebench R20, the pattern holds: 6323 against 5673 in multi-core (11.5% ahead) and 892 versus 800 in single-core (11.5% ahead). The newest Cinebench R23 tests confirm the trend, with the EPYC 7232P posting 15055 versus 13509 in multi-core (11.4% lead) and 2125 versus 1907 in single-core (11.4% lead).

The consistency of the delta is notable. Whether the workload is single-threaded or fully threaded, the EPYC 7232P maintains roughly the same advantage. This suggests the performance gap is systematic rather than workload-specific. The Core i9-9900 never manages a single victory in the recorded head-to-head data, giving the EPYC 7232P a clean 6-0 record.

Average benchmark scores reinforce the picture. The EPYC 7232P has an average score of 4354 across its benchmark suite, placing it at the 58th percentile of all CPUs. The Core i9-9900 averages 4163, at the 57th percentile. The 4.6% difference in average scores is smaller than the head-to-head deltas because the averages include different benchmark sets, but the direction is consistent.

The nearest rivals for each processor further contextualize these results. The EPYC 7232P sits within 1.3% of the AMD Ryzen 7 PRO 5750G (which scores 4296) and within 0.8% of the Intel Core i7-7820X (4321). It trails the Intel Xeon E-2288G by only 0.4% (4373) and the AMD Ryzen 7 PRO 4750GE by 1.3% (4411). The Core i9-9900, meanwhile, is within 1.2% of the AMD Ryzen 7 PRO 2700X (4114) and within 1% of the AMD Ryzen 9 5980HS (4121). It leads the Intel Core i5-12500T by 1.3% (4216) and trails the Intel Core i5-11500H by 0.6% (4187).

Where Each One Wins

The data shows a single clear winner across all tested scenarios, but the two processors serve different use cases based on their platform characteristics rather than benchmark results alone.

The AMD EPYC 7232P wins every compute benchmark recorded. Its 11.5% lead in single-core tests indicates that even lightly threaded applications will run faster on the EPYC platform. Its 11.4% to 11.5% lead in multi-core tests means heavily threaded workloads such as video rendering, scientific computing, and server-side compilation will see measurable improvements. The EPYC 7232P also supports eight-channel memory with a recorded bandwidth of 85.3 GB/s, compared to the Core i9-9900's dual-channel 42.7 GB/s. This memory bandwidth advantage, while not directly benchmarked in the head-to-head tests, positions the EPYC 7232P for memory-intensive workloads such as large in-memory databases or high-performance computing tasks.

The Intel Core i9-9900 wins in platform flexibility for desktop users. It includes integrated graphics (UHD Graphics 630), which the EPYC 7232P lacks entirely. For a desktop system without a discrete GPU, the Core i9-9900 can operate standalone. The EPYC 7232P requires a separate graphics solution. The Core i9-9900 also has a lower TDP of 65 watts compared to 120 watts for the EPYC 7232P, which may simplify cooling in compact desktop builds, though the EPYC's socket (AMD Socket SP3) targets server/workstation chassis where higher cooling capacity is standard.

The Core i9-9900 uses the Intel Socket 1151 platform, which is common in consumer desktop motherboards. The EPYC 7232P uses AMD Socket SP3, a server platform. Users with existing desktop infrastructure will find the Core i9-9900 easier to integrate. However, the benchmark data does not favor the Core i9-9900 in any compute test, so its advantages are purely platform-level.

The Verdict

The recorded data leads to a straightforward conclusion: the AMD EPYC 7232P outperforms the Intel Core i9-9900 in every measured benchmark. If the decision is based purely on compute performance, the EPYC 7232P is the stronger processor. It delivers an 11.5% advantage in both single-core and multi-core Cinebench R15 and R20 tests, and an 11.4% advantage in R23 tests. No workload category in the data favors the Intel part.

Memory bandwidth strongly favors the EPYC 7232P as well. Its eight-channel memory bus provides 85.3 GB/s, exactly double the 42.7 GB/s of the Core i9-9900's dual-channel configuration. For workloads that saturate memory bandwidth, the EPYC 7232P will pull further ahead than the raw compute benchmarks suggest.

The Core i9-9900 is the choice only when platform constraints dominate. Its integrated UHD Graphics 630 means a system can be built without a discrete GPU. Its 65-watt TDP is nearly half the EPYC 7232P's 120 watts, which may matter in space-constrained or thermally limited desktop builds. Its Socket 1151 platform is a mainstream desktop standard, whereas the EPYC's SP3 socket requires server/workstation motherboards. The Core i9-9900 is also marked as end-of-life production status, while the EPYC 7232P is active.

For anyone building a server or workstation where CPU compute is the priority, the EPYC 7232P wins on the data. For a desktop where integrated graphics and lower power draw are essential, the Core i9-9900 remains viable despite losing every benchmark.
