AMD EPYC 4464P

The AMD EPYC 4464P presents a distinctive profile within the EPYC 4004 series, leveraging a 12-core, 24-thread Zen 4 design on the AMD Socket AM5 platform. Its benchmark results reveal a processor engineered for a specific balance of high-frequency responsiveness and substantial parallel throughput, placing it in the 95th percentile of all CPUs tracked. The data suggests a part that defies simple categorization, straddling the line between enterprise server duties and high-end desktop performance expectations.

Single-Thread vs Multi-Thread Behavior

The performance split between single-thread and multi-thread workloads is telling. In Cinebench R23, the processor scores 5,677 points in single-core and 40,215 points in multi-core. The ratio between these scores is roughly 7.1x, indicating that while the 12 physical cores scale effectively, the architecture prioritizes per-thread responsiveness more than a traditional server part might. This is reinforced by the R20 results, which show a single-core score of 2,384 and a multi-core score of 16,890.

This behavior implies that the EPYC 4464P is not purely a throughput monster. The 5.40 GHz boost clock is a significant factor here; it allows lightly-threaded tasks such as database queries, spreadsheet recalculation, or legacy software to execute with minimal latency. Conversely, the multi-thread scores confirm that when all 24 threads are engaged, the chip can sustain heavy parallel loads like video encoding or virtualization workloads. The PassMark data offers further insight: a single-thread score of 4,130 and a multithread score of 47,312. The ratio here is approximately 11.5x, which is higher than the Cinebench ratio, suggesting that different workloads scale differently with thread count—some are more memory-bound or cache-sensitive, while others rely purely on core count.

For real-world use, this split suggests a processor that excels in mixed environments. A developer compiling code will see strong multi-thread performance, but the same machine will feel snappy for UI interactions or single-threaded script execution. The data indicates that the EPYC 4464P does not sacrifice single-thread agility for core count, a common compromise in many server processors. This is a notable architectural achievement, positioning it as a versatile option for single-socket workstations where both interactive and batch tasks coexist.

Power and Thermals

The thermal design profile is listed at 65W TDP, which is remarkably low for a 12-core, 24-thread processor capable of a 5.40 GHz boost. This figure places it firmly in an efficiency-oriented class, suggesting that the EPYC 4464P can be cooled by a modest air cooler rather than requiring a complex liquid cooling loop. The low TDP is a direct consequence of the 5nm process node from TSMC, which allows for high clock speeds without proportional increases in power draw.

The implications for system design are substantial. A 65W TDP means that system integrators and DIY builders can use smaller power supplies and less bulky cooling solutions, reducing overall system cost and noise. This is atypical for the EPYC brand, which is often associated with high-core-count parts that demand robust thermal solutions. The data implies that the 4464P is designed for density and quiet operation, making it suitable for compact workstations or office environments where acoustic footprint matters. It also suggests a higher sustained boost capability under all-core loads, as the thermal headroom is generous relative to the power budget. The lack of an unlocked multiplier indicates that users are expected to run the chip within its specified power envelope, relying on the factory-tuned boost behavior rather than manual overclocking.

Benchmark Performance

The benchmark scores paint a picture of a processor that punches above its weight class. The Cinebench R23 multi-core score of 40,215 is a strong result, placing it within striking distance of much larger and more power-hungry parts. Compared to its nearest rivals, the data shows a tight cluster. The AMD EPYC 9124 averages a score of 65,104, which is 0.5% lower than the 4464P’s average of 64,756. This is a negligible margin, indicating near-parity in overall benchmark output. The EPYC 7343 trails by 0.9%, while the Intel Core Ultra 7 265 is 1% behind, and the Intel Core i9-13900KS is 1.2% behind.

These small deltas are remarkable given the architectural differences. The EPYC 4464P achieves its average score with just 12 cores, while some rivals may rely on higher core counts or different memory configurations. The PassMark sub-tests reveal specific strengths. The integer math score of 160,011 and floating-point math score of 91,668 suggest robust general-purpose compute capability. Data compression at 575,076 and encryption at 36,227 show strong performance for storage and security-related tasks. The extended instructions score of 38,866 indicates good support for modern SIMD workloads.

However, the physics score of 2,879 is notably lower relative to the other sub-scores, and the find prime numbers score of 327 is surprisingly modest. This suggests that while the processor excels at parallelizable integer and floating-point operations, certain specialized or latency-sensitive algorithms may not benefit as much from its architecture. The random string sorting score of 70,443 is also competitive, indicating solid memory subsystem performance for a dual-channel platform.

How It Compares

AMD EPYC 9124: The 9124 is essentially a statistical tie with the 4464P, being only 0.5% slower in average benchmark score. This is notable because the 9124 is a different class of server processor, likely with a higher core count. The data suggests that the 4464P’s high boost clock compensates for any core count disadvantage, making it a viable alternative in workloads that are not perfectly parallelized.

AMD EPYC 7343: The 7343 is 0.9% slower than the 4464P. This older EPYC part, based on a previous generation, is edged out by the newer Zen 4 architecture’s IPC and clock speed advantages. The margin is small, but it demonstrates that the 4464P offers generational efficiency gains without a significant performance penalty.

Intel Core Ultra 7 265: The 265 is 1% slower than the 4464P. This comparison is interesting because the Ultra 7 is a consumer desktop processor, while the 4464P is a workstation/server part. The data shows that the EPYC 4464P can match or slightly exceed a high-end consumer chip in average performance, while offering ECC memory support and server-grade features.

Intel Core i9-13900KS: The i9-13900KS is 1.2% slower than the 4464P. This is a flagship consumer processor known for extreme boost clocks. The fact that the 4464P slightly edges it out in average benchmark score is a testament to the efficiency of the Zen 4 architecture at a much lower TDP. The 65W TDP versus the i9’s typically much higher power draw makes the 4464P a compelling efficiency champion.
