About AMD EPYC 7453
The AMD EPYC 7453 is a 28-core, 56-thread Zen 3 processor built for the EPYC 7003 series, targeting the server and workstation segment on the AMD Socket SP3 platform. It combines a 2.75 GHz base clock with a 3.45 GHz boost clock, drawing up to 225 W, and supports DDR4 memory across an eight-channel bus. Its benchmark profile reveals a processor that is highly capable in multi-threaded workloads but sits in a surprisingly competitive position against much smaller consumer and entry-level server parts in average scoring.
Benchmark Performance
The EPYC 7453 delivers an average benchmark score of 11912, placing it in the 71st percentile of all CPUs. This is a strong showing, but the deltaPct figures against its nearest rivals reveal a tighter race than the core count suggests. The data shows the EPYC 7453 trails the AMD Ryzen 5 3500X by a mere 0.6% in average score, the Intel Xeon Bronze 3408U by 0.9%, the Intel Xeon Gold 6314U by 0.9%, and the Intel Core i7-6700 by 1.2%. These are negligible margins, indicating that in aggregate benchmark terms, the EPYC 7453 is statistically on par with these processors, despite being a 28-core server part.
Looking at specific multi-core workloads, the EPYC 7453’s strength becomes evident. In Cinebench R23 multi-core, it scores 41185, which is a substantial result that reflects the benefit of its 28 cores and 56 threads. The Cinebench R20 multi-core score of 17297 and Cinebench R15 multi-core score of 4151 follow the same pattern, with the processor scaling well across rendering tasks that utilize all available threads. These numbers indicate that the EPYC 7453 is a formidable performer in heavily parallelized applications, where its core count allows it to pull ahead of lower-core-count rivals despite similar average scores.
However, the single-core results tell a different story. In Cinebench R23 single-core, the EPYC 7453 scores 5814, with Cinebench R20 single-core at 2441 and Cinebench R15 single-core at 585. These are respectable figures for a server chip, but they do not match the raw per-core performance of newer or higher-clocked consumer parts. The gap between its multi-core and single-core scores is the defining characteristic of this processor: it is built for throughput, not for latency-sensitive single-threaded tasks. The average benchmark score of 11912, which pulls the EPYC 7453 down relative to its multi-core peak, reflects this imbalance—the single-thread tests drag the aggregate down, while multi-thread tests push it up.
Who Should Consider It
The EPYC 7453 is clearly aimed at server and workstation environments where multi-threaded performance is paramount. The data shows that in Cinebench R23 multi-core, the EPYC 7453 achieves a score of 41185, which is roughly 7 times its single-core score of 5814. This ratio indicates that the processor excels in tasks like 3D rendering, video encoding, scientific simulation, and virtual machine hosting, where all 28 cores and 56 threads can be kept busy. For database workloads, compilation jobs, or any batch processing that scales with core count, the EPYC 7453 is a strong candidate.
Gaming is not a primary use case for this processor, given its server pedigree and the single-core performance profile. While the Cinebench R23 single-core score of 5814 is not weak, it is not the differentiator that gamers look for, and the 225 W TDP suggests a platform designed for sustained all-core loads rather than bursty gaming sessions. Office productivity and general desktop use would also be underutilized, as these tasks rarely leverage more than a few threads, and the EPYC 7453’s advantage in multi-core scores would go untapped. The processor is best suited for professionals running multi-threaded applications that can saturate its 28 cores, where the benchmark results show it delivers top-tier throughput.
Single-Thread vs Multi-Thread Behavior
The split between single-thread and multi-thread performance is stark and defines the EPYC 7453’s personality. In Cinebench R23, the multi-core score of 41185 is over 6 times the single-core score of 5814, a ratio that is typical of high-core-count server chips. This means that any workload that is not fully parallelized will see only a fraction of the processor’s potential. For example, a single-threaded application will run at the speed of one core, boosted to 3.45 GHz, which is adequate but not exceptional. The Cinebench R20 single-core score of 2441 and R15 single-core score of 585 confirm this: the EPYC 7453 is competitive but not class-leading in single-threaded tasks.
Real-world implications are clear. Software that relies on a few fast cores, such as older games or legacy applications, will not benefit from the EPYC 7453’s core count. Conversely, modern rendering engines, physics simulations, and data processing tools that are designed for multi-threading will see near-linear scaling, as evidenced by the multi-core scores. The 64 MB of shared L3 cache helps mitigate some of the latency in multi-threaded workloads, allowing the 28 cores to share data efficiently. The eight-channel DDR4 memory bus, with 204.8 GB/s of bandwidth, further supports parallel tasks by ensuring that all cores have ample memory throughput. The benchmark data suggests that the EPYC 7453 is a specialist: it sacrifices some single-core performance for massive multi-core throughput, making it ideal for servers that run many concurrent threads.

How It Compares
AMD Ryzen 5 3500X: The EPYC 7453 trails the Ryzen 5 3500X by just 0.6% in average benchmark score, a negligible difference. However, the Ryzen 5 3500X is a consumer chip with far fewer cores, so the EPYC 7453’s multi-core Cinebench R23 score of 41185 vastly exceeds what the 3500X can achieve in threaded workloads. The similar average score is due to the EPYC 7453’s lower single-core performance pulling its aggregate down.
Intel Xeon Bronze 3408U: The EPYC 7453 is 0.9% behind the Xeon Bronze 3408U in average score. Both are server processors, but the EPYC 7453 offers 28 cores versus the Bronze’s lower count, giving it a significant advantage in multi-threaded benchmarks like Cinebench R23, where it scores 41185. The close average score suggests the Bronze 3408U has stronger single-core performance, but the EPYC 7453 is built for parallel throughput.
Intel Xeon Gold 6314U: The EPYC 7453 matches the Xeon Gold 6314U within 0.9% in average score. Both are high-core-count server chips, and the benchmark data indicates they are comparable in overall performance. The EPYC 7453’s Cinebench R23 multi-core score of 41185 demonstrates its capability in rendering and similar tasks, making it a direct competitor in the server segment.
Intel Core i7-6700: The EPYC 7453 is 1.2% behind the Core i7-6700 in average score, which is surprising given the i7-6700 is a much older consumer processor. The i7-6700 likely has superior single-core performance, allowing it to keep the average score close, but the EPYC 7453 dominates in multi-core workloads with its 28 cores, as shown by the Cinebench R23 multi-core score of 41185. This comparison highlights the EPYC 7453’s focus on multi-threaded efficiency over single-core speed.
