AMD EPYC 9474F

The AMD EPYC 9474F is a 48-core, 96-thread Zen 4 server processor built for the EPYC 9004 series, targeting dual-socket and high-density compute platforms. With a base clock of 3.60 GHz and a boost clock of 4.10 GHz, it sits in the high-frequency segment of the Genoa lineup, trading some core count for higher clock speeds compared to standard EPYC parts. The data positions this chip as a broad-spectrum performer, with an average benchmark score of 25103 placing it in the 82nd percentile among all CPUs, indicating it handles both parallel throughput and responsive single-threaded tasks effectively.

Platform and Compatibility

The EPYC 9474F uses AMD Socket SP5, the platform designed for the entire EPYC 9004 generation. This socket is exclusive to server and workstation motherboards, meaning the upgrade path is tied to enterprise-class platforms rather than consumer boards. The architecture is Zen 4 on TSMC's 5 nm process, with the "Genoa" codename, and the chip is built from 8 separate 72 mm² dies, totaling 52,560 million transistors. This chiplet design is central to the platform's scalability, allowing AMD to produce multiple SKUs from the same silicon.

Memory support is DDR5, operating on a twelve-channel memory bus, yielding a peak memory bandwidth of 460.8 GB/s. This is a critical specification for the processor's intended workloads, as data movement is often the bottleneck in scientific computing and large database operations. ECC memory is supported, which is non-negotiable for data integrity in server environments where a single bit flip can corrupt results. The platform also provides Gen 5 PCIe with 128 lanes from the CPU alone, enabling massive I/O expansion for GPUs, NVMe storage arrays, and high-speed network adapters without needing a separate chipset.

The production status is active, and the launch date was November 9, 2022. Since the socket and memory standard are shared across the entire EPYC 9004 family, systems built around the 9474F can be upgraded to higher-core-count parts in the same generation without a platform change, though the physical socket and memory infrastructure must be purchased anew if coming from older EPYC platforms. The lack of an integrated GPU means a discrete graphics adapter is mandatory for any display output, which is standard for this market segment.

Single-Thread vs Multi-Thread Behavior

The benchmark split reveals a processor that is unusually balanced for a server part. In Cinebench R23, the single-core score is 12252, while the multi-core score is 86790, giving a ratio of roughly 7:1. This indicates that while the 48 cores provide substantial parallel throughput, the per-core performance is not sacrificed. The boost clock of 4.10 GHz is high for a 360 W TDP part, and the Zen 4 architecture's IPC gains over prior generations are evident in the single-thread numbers.

In Cinebench R20, the single-core score of 5145 and multi-core score of 36451 follow the same pattern. The single-thread performance is competitive with high-end desktop processors, which is unusual because many server chips prioritize core count over clock speed. This behavior matters for real workloads: applications with serial sections, such as database query planners, compilation front-ends, or single-threaded scripting, will not stall the entire system. The multi-thread scores, meanwhile, scale impressively across the 96 threads, confirming that the chip can maintain high utilization across all cores when the workload allows.

The Cinebench R15 results (1234 single-core, 8748 multi-core) show the same trend, with the multi-core score being over seven times the single-core score. This consistency across benchmark versions indicates that the performance scaling is not an artifact of a specific test but a fundamental property of the chip's design. For mixed workloads—like a virtualized host running many VMs, where some are lightly threaded and others are heavily parallel—this balance is a distinct advantage.

Power and Thermals

The TDP is 360 W, which defines the thermal design envelope for the processor. This is a high-power part, requiring a robust cooling solution. The data does not specify a particular cooler type, but the thermal dissipation requirements imply a large heatsink with high airflow, likely a passive heatsink with chassis-level fans or an active cooler designed for server sockets. Liquid cooling is not a necessity but may be preferred in dense rack configurations where ambient temperatures are high.

The 5 nm process node helps manage power efficiency relative to the core count, but 48 cores at 3.60 GHz base still draw significant current under load. The boost behavior indicates that the chip can sustain 4.10 GHz on some cores while managing thermals across the package. In practice, the cooling tier required is comparable to other 300-watt-class server processors: a high-end air cooler for a workstation chassis or a custom server cooling solution for a rack mount. The lack of an unlocked multiplier means overclocking is not a consideration; the chip runs at its specified clocks under the platform's power management.

How It Compares

The nearest rivals, based on average benchmark score, are a mix of desktop and mobile parts that happen to fall within 0.4% of the EPYC 9474F's average. This is a statistical artifact of the averaging method, as these rivals have vastly different core counts and power envelopes. The AMD Ryzen AI 5 PRO 340 (average score 25099) is a low-power mobile APU, and the delta of 0% means the EPYC 9474F effectively matches it in the aggregate metric, despite having 48 cores versus the Ryzen's far fewer.

The AMD Ryzen 5 8400F (average score 25064) is a 6-core desktop chip, and the EPYC is 0.2% ahead. The AMD Ryzen 7 2700X (average score 25057) is an older 8-core part, and the EPYC is also 0.2% ahead. The Intel Core i7-13620H (average score 25201) is a mobile processor, and the EPYC trails it by 0.4%. These deltas are negligible in real-world terms; they indicate that the average benchmark score, which weights all tests equally, is not a useful metric for comparing a 48-core server chip to desktop or mobile parts.

The appropriate comparison would be against other EPYC 9004 parts, but those are not listed in the nearest rivals. The data provided only includes these four entries, so the analysis must be limited to what is given. The key insight is that the EPYC 9474F's average score is dominated by its multi-core performance, while the rivals' averages are dominated by single-core performance, yet the aggregate lands in the same range.

Benchmark Performance

Looking at the specific Cinebench scores provides a clearer picture than the average. In Cinebench R23 multi-core, the EPYC 9474F scores 86790. The nearest rival with a comparable multi-core score is not listed, but the delta of 0.2% against the Ryzen 5 8400F in average score means the EPYC is roughly equal in the aggregate. However, in R23 single-core, the EPYC's 12252 is likely far higher than the Ryzen 5 8400F's single-core score, but that specific number is not in the fact pack.

The multi-core scores across all Cinebench versions show strong scaling: 8748 in R15, 36451 in R20, and 86790 in R23. The ratio of R23 to R20 is about 2.38, which is consistent with the typical workload scaling between those benchmark versions. The single-core scores also scale predictably: 1234 in R15, 5145 in R20, and 12252 in R23. The R20 to R23 single-core ratio is about 2.38 as well, indicating that the chip's per-core performance is stable across these tests.

The percentile rank of 82 means that 82% of all CPUs in the database score lower on average. This is a high percentile, but it is pulled down by the fact that the average includes many low-power mobile and desktop parts. For a server chip, the more relevant comparison is against other high-core-count parts, but those are not in the nearest rivals. The data shows that the EPYC 9474F delivers exceptional multi-threaded throughput, with the single-thread performance being a secondary but still strong attribute.

Who Should Consider It

The EPYC 9474F is suited for workloads that require both high core counts and high clock speeds. In Cinebench R23, the multi-core score of 86790 places it in the top tier for rendering and video encoding, where all 48 cores can be fully utilized. The single-core score of 12252 means that tasks like software compilation, which often have serial bottlenecks, will not be hampered. This makes it a strong candidate for a build server or a scientific computing node running a mix of parallel and sequential code.

For gaming, this processor is overkill in terms of core count, and the lack of integrated graphics means a discrete GPU is required. The high single-thread performance would not hurt gaming, but the 360 W TDP and server platform costs are not justified for a gaming-centric build. The data does not include gaming benchmarks, so no specific claims can be made about frame rates.

For office and general productivity, the EPYC 9474F is excessive. A 48-core server chip in an office PC would be wasteful in power and cost. The benchmark percentile of 82 indicates it outperforms most CPUs, but the target audience is clearly server and workstation buyers who need the memory bandwidth and PCIe lanes for professional applications like large-scale simulation, financial modeling, or virtualized infrastructure. The twelve-channel DDR5 support and 128 PCIe Gen 5 lanes are the features that matter most for these users, and the Cinebench scores confirm the processing power to feed those I/O subsystems.
