AMD EPYC 4464P vs Intel Core 9 273PQE Comparison

The Intel Core 9 273PQE and AMD EPYC 4464P are both 12-core, 24-thread processors, yet they occupy different corners of the market: one is a desktop part, the other a server/workstation chip. Benchmark results show a clear split in their strengths, with the AMD EPYC 4464P taking 12 of the 17 head-to-head comparisons, while the Intel Core 9 273PQE wins 5. The data reveals that the EPYC 4464P dominates in multi-threaded and integer-heavy workloads, while the Core 9 273PQE pulls ahead decisively in floating-point math and single-threaded tasks. Their average benchmark scores are close—66099 for the Intel part versus 64823 for the AMD part—but the distribution of wins tells a more nuanced story about where each processor excels.

Head-to-Head Benchmarks

The AMD EPYC 4464P establishes a consistent lead across every Cinebench test, though the margins are narrow. In Cinebench R23 multicore, the EPYC scores 40215 against the Core 9's 39190, a 2.5% advantage. The same pattern holds in Cinebench R20 multicore (16890 vs 16459, -2.6%) and Cinebench R15 multicore (4053 vs 3950, -2.5%). Single-core Cinebench results follow suit, with the EPYC leading by 2.6% in R23 (5677 vs 5532), R20 (2384 vs 2323), and R15 (572 vs 557). These are consistent, if modest, victories across all render workloads.

The largest single win for the AMD EPYC 4464P comes in PassMark's find prime numbers test, where it scores 343 against the Intel part's 198—a massive 42.3% gap. This is a pure integer performance test, and the EPYC's Zen 4 architecture shows a clear edge here. Similarly, in random string sorting, the EPYC leads 70200 to 53167, a 24.3% advantage. Data encryption also favors the EPYC heavily, with scores of 35816 versus 29636, a 17.3% difference. These three tests demonstrate where the AMD chip's strengths lie: heavily parallel, integer-based operations.

The Intel Core 9 273PQE fights back in floating-point math, where it scores 125546 against the EPYC's 93090—a commanding 34.9% lead. This is the largest margin of victory in either direction across all benchmarks. The Intel part also wins in PassMark single-thread tests, scoring 4573 versus 4146, a 10.3% advantage. In integer math, the Intel chip edges ahead 164629 to 160410 (2.6%), and in data compression it leads 585752 to 574304 (2%). These wins indicate that while the EPYC handles many multi-threaded workloads well, the Core 9 273PQE has superior per-core floating-point and single-threaded capabilities.

Other benchmarks show narrower results. In PassMark multithread, the EPYC wins 47514 to 46107 (-3%), and in physics it takes 2873 to 2754 (-4.1%). Extended instructions go to the EPYC 39359 to 38743 (-1.6%). The overall picture is one of specialization: the AMD EPYC 4464P is the default choice for integer-heavy, multi-threaded server tasks, while the Intel Core 9 273PQE excels in floating-point and single-threaded scenarios.

The Verdict

The data points to a clear split. The AMD EPYC 4464P is the better choice for workloads that rely on integer math, encryption, and string manipulation, as evidenced by its 42.3% lead in prime number finding and 24.3% lead in random string sorting. It also wins every Cinebench render test, though by only 2.5–2.6%. For users running these types of workloads, the EPYC's consistent multi-threaded edge makes it the stronger option.

The Intel Core 9 273PQE is the better pick for single-threaded and floating-point-intensive applications. Its 34.9% lead in floating-point math is the standout result, and its 10.3% advantage in PassMark single-thread tests confirms its per-core strength. Both processors sit at the 93rd percentile versus all CPUs, indicating they are both high-end parts, but their benchmark profiles suggest different optimal use cases.

Considering the average benchmark scores, the Intel Core 9 273PQE (66099) is marginally ahead of the AMD EPYC 4464P (64823), a difference of about 1.9%. However, the EPYC's nearest rivals list includes the AMD EPYC 4465P at 66925 and the Intel Core Ultra 5 250K Plus at 66855, while the Intel part's rivals include the AMD Ryzen 9 7950X3D at 65914. This suggests that both chips are competitive with similar-tier products in their respective ecosystems, but the choice between them should be driven by workload specifics rather than overall averages.

Where Each One Wins

The AMD EPYC 4464P wins in scenarios involving data encryption, integer calculations, and multi-threaded throughput. Its 17.3% lead in encryption, 42.3% lead in prime numbers, and 24.3% lead in random string sorting make it the clear choice for database operations, cryptographic tasks, and any workload that processes large amounts of integer data. It also wins in all Cinebench tests, so rendering tasks that use these benchmarks will favor the EPYC, albeit by a small margin.

The Intel Core 9 273PQE wins in floating-point math, single-threaded performance, integer math, and data compression. Its 34.9% lead in floating-point math is significant for scientific computing, simulations, and any application that relies heavily on floating-point operations. The 10.3% single-thread advantage means that legacy software or applications with limited parallelism will run faster on the Intel part. The 2% lead in data compression and 2.6% lead in integer math are smaller but still indicate an edge in those areas.

The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and a larger 64 MB of shared L3 cache. The EPYC also has a stated transistor count of 13,140 million and a die size of 2x 71 mm², while the Intel part does not list these figures.

The AMD EPYC 4464P belongs to the EPYC 4004 series and is classified as a Server/Workstation part, while the Intel Core 9 273PQE is a Desktop processor. This positioning is reflected in their PCIe lane counts: the EPYC offers 28 Gen 5 lanes from the CPU, while the Intel part offers 16. Both support DDR5 memory, but the Intel part also supports DDR4. The EPYC includes Radeon Graphics as integrated graphics, while the Intel part has UHD Graphics 770.

Specification Differences

The most obvious differences lie in clock speeds and power. The AMD EPYC 4464P has a higher base clock of 3.70 GHz versus the Intel's 3.40 GHz, but the Intel part has a higher boost clock of 5.90 GHz versus the EPYC's 5.40 GHz. The EPYC has a much lower TDP of 65 watts, compared to the Intel part's 125 watts.

Memory bandwidth favors the Intel part, with 89.6 GB/s versus the EPYC's 83.2 GB/s. Both use dual-channel memory buses, but the Intel part supports both DDR4 and DDR5, while the EPYC supports only DDR5. The EPYC offers more PCIe lanes (28 vs 16), both Gen 5.

The release dates differ: the AMD EPYC 4464P was released on 2024-05-20, while the Intel Core 9 273PQE has a release date of 2026-03-08.
