AMD EPYC 7413

The AMD EPYC 7413 is a 24-core, 48-thread server processor built on the Zen 3 architecture and the Milan codename, part of the EPYC 7003 series. It carries a launch MSRP of $1825 and sits in the 97th percentile of all CPUs in the benchmark database, with an average benchmark score of 80041. That score places it within a hair of several flagship desktop processors, a remarkable result for a chip aimed at servers and workstations.

Benchmark Performance

The EPYC 7413 delivers strong multi-threaded throughput across every test in the database. In Cinebench R23, it scores 43044 in multi-core and 6076 in single-core; the R20 run produces 18078 and 2551, while R15 yields 4338 and 612. The multi-core figures are especially telling: the R23 multi-core result is roughly 7.1 times the single-core number, indicating that the 24 cores and 48 threads scale efficiently under parallel loads. That scaling is typical of a high-core-count server part, but the absolute numbers are competitive with the top consumer chips. The average benchmark score of 80041 is essentially tied with the Intel Core i9-14900K, which posts 79824, a delta of just 0.3%. The i9-14900KF, Core Ultra 7 265KF, and Core Ultra 7 265K trail by 1.0%, 1.0%, and 1.2% respectively, with scores of 79245, 79240, and 79102. In other words, the EPYC 7413 sits at the very top of the performance pyramid, even though it is designed for a different market segment.

PassMark results reinforce this picture. The multithread score of 50641 is exceptionally high, while the single-thread score of 2400 is more modest. Integer math hits 215629, floating-point math 118881, and data compression 715616. Encryption workloads score 48492, extended instructions 45696, and random string sorting 81134. Physics computes 4708, and the find-prime-numbers test yields 397. These numbers point to a processor that excels at sustained, parallel tasks — compression, encryption, and numerical simulation — while single-threaded responsiveness is adequate but not class-leading.

Platform and Compatibility

The EPYC 7413 uses the AMD Socket SP3, a mature server socket that supports the entire EPYC 7003 family. Memory support is DDR4 with an eight-channel interface, delivering a theoretical bandwidth of 204.8 GB/s, and ECC is enabled, which is essential for error-sensitive server workloads. PCIe connectivity is Gen 4 with 128 lanes available from the CPU itself, providing ample room for high-speed storage, accelerators, and networking. The chip is fabricated on TSMC's 7 nm process, with 16,600 million transistors spread across four 81 mm² dies. This design choice balances power and thermal density: the 180 W TDP is high but manageable in a server chassis with adequate cooling. The processor is not multiplier-unlocked, which is standard for EPYC parts, and its boost clock of 3.60 GHz is modest compared to consumer desktop chips, but the architecture compensates through core count and memory bandwidth. The platform is clearly built for long-running, high-throughput workloads rather than short bursty tasks.

Who Should Consider It

The EPYC 7413 is a natural fit for environments where multi-threaded performance is the primary requirement. Data centers running virtualization, database engines, or batch processing will benefit from the 24 cores and 48 threads, especially when combined with the 128 MB of shared L3 cache and eight-channel memory. Workstation users who render 3D scenes, simulate physics, or process large datasets will see strong scaling in Cinebench R23 (43044) and PassMark multithread (50641). The high data compression score (715616) suggests it is well suited for archival and backup systems, while the encryption score (48492) indicates capability in secure communication or storage encryption tasks. The single-thread performance, while not exceptional, is still respectable — Cinebench R23 single-core at 6076 and PassMark single-thread at 2400 — so it can handle light interactive workloads, but it is not optimized for latency-sensitive applications like gaming or desktop productivity. For those workloads, a lower-core-count, higher-clock processor would be more appropriate. In short, this is a chip for heavy lifting, not for snappy UI responsiveness.

How It Compares

The nearest rival, the Intel Core i9-14900K, posts an average score of 79824, a 0.3% deficit relative to the EPYC 7413. That difference is negligible, meaning the two processors are effectively interchangeable in overall benchmark performance. However, the i9-14900K is a consumer desktop chip with a much higher boost clock and a completely different platform, so the comparison is more about raw compute than platform fit.

The i9-14900KF trails by 1.0% with an average score of 79245. This is a minor gap, and again, the EPYC 7413 holds its own despite being a server part. The KF variant lacks integrated graphics, but that does not affect CPU benchmarks.

The Core Ultra 7 265KF scores 79240, also 1.0% behind. This is another desktop chip aimed at high-end gaming and productivity. The EPYC 7413 matches it in average performance, which is a strong statement about the efficiency of the Zen 3 architecture at high core counts.

Finally, the Core Ultra 7 265K scores 79102, a 1.2% deficit. The gap is slightly larger but still within a rounding error in real-world terms. All four rivals are consumer-grade processors, yet the EPYC 7413 edges them out in the aggregate benchmark suite. This demonstrates that a well-designed server CPU can compete with flagship desktop silicon on raw throughput, even though the desktop parts will likely win in single-threaded tasks and power efficiency at the wall.

Single-Thread vs Multi-Thread Behavior

The EPYC 7413 exhibits a clear split between its single-thread and multi-thread performance. In Cinebench R23, the single-core score of 6076 is about 14% of the multi-core score of 43044, a ratio of roughly 7.1. That is exactly what one would expect from a 24-core, 48-thread processor with a modest 3.60 GHz boost clock. The PassMark results show an even starker contrast: single-thread at 2400 versus multithread at 50641, a ratio of over 21. This extreme divergence highlights the processor's design philosophy: it prioritizes parallel throughput over single-thread responsiveness. For workloads that can utilize many threads — rendering, scientific computing, data analysis, compression — the EPYC 7413 delivers outstanding performance. For single-threaded tasks, such as older software or lightly threaded applications, the processor will not feel as fast as a modern desktop chip with a 5 GHz boost clock, but it will still handle them adequately. The benchmark data consistently shows that the EPYC 7413 is a workhorse for multi-threaded environments, and its place in the 97th percentile of all CPUs confirms that it is among the fastest processors available today, regardless of market segment.
