AMD EPYC 4484PX vs AMD Ryzen 7 9700F Comparison

AMD Ryzen 7 9700F vs AMD EPYC 4484PX: a desktop Zen 5 chip against a server/workstation Zen 4 part. The data shows a clear split: the Ryzen takes the single-thread crown, while the EPYC dominates almost every multi-threaded and throughput-oriented workload. Both CPUs sit at the 94th percentile among all CPUs in the database, but they achieve that standing through very different strengths.

Where Each One Wins

The AMD Ryzen 7 9700F wins in single-thread performance. Its PassMark single-thread score of 4691 beats the EPYC 4484PX’s 4119 by 13.9%. That makes it the better choice for lightly threaded applications, response-time-sensitive tasks, and any workload that relies on one or two fast cores. The Ryzen’s 5.50 GHz boost clock and Zen 5 architecture support this result, and its unlockable multiplier means it is positioned for tweaking.

The AMD EPYC 4484PX wins nearly everywhere else. Out of 11 shared benchmark comparisons, it takes 9. The biggest margins come in prime number finding and physics, where it leads by 56.9% and 57% respectively. It also wins multithreaded performance by 27.8%, data compression by 30.1%, encryption by 41.1%, and integer math by 25.9%. The EPYC’s 12 cores, 24 threads, and 128 MB of L3 cache give it a decisive edge in server, workstation, and content-creation workloads that scale across cores. Its 120 W TDP and locked multiplier reflect its intended role as a stable, always-on compute part rather than an overclocking toy.

Architecture Differences

The two chips come from different generations of AMD’s core designs. The Ryzen 7 9700F uses Zen 5 on a 4 nm TSMC process, with the Granite Ridge codename. It packs 8,315 million transistors into a 70.6 mm² die. The EPYC 4484PX uses Zen 4 on a 5 nm TSMC process, with the Raphael codename, and it is built from two 71 mm² dies totaling 17,840 million transistors.

Cache configurations differ sharply. The Ryzen has 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The EPYC has 64 KB of L1 per core, 1 MB of L2 per core, and a much larger 128 MB of shared L3, plus a 1x 64 MB 3D V-Cache slice. That extra cache is a major reason the EPYC excels in data-heavy and physics-based tests.

Memory support is similar in type but not bandwidth. Both support DDR5 and dual-channel memory. The Ryzen lists 89.6 GB/s of memory bandwidth, while the EPYC lists 83.2 GB/s. Both support ECC memory. The Ryzen has no integrated graphics, while the EPYC includes Radeon Graphics.

PCIe connectivity also differs. The Ryzen offers Gen 5 with 24 lanes from the CPU, while the EPYC offers Gen 5 with 28 lanes. Both use AMD Socket AM5. The Ryzen was released later, on 2025-09-15, with a launch MSRP of $289. The EPYC launched on 2024-05-20, with a launch MSRP of $599.

Head-to-Head Benchmarks

The EPYC’s lead in parallel workloads is consistent and large. In PassMark multithread, it scores 50547 versus 36470, a 27.8% advantage. Data compression shows 603371 versus 421988, a 30.1% gap. Data encryption is even more lopsided: 36499 versus 21488, a 41.1% difference. Extended instructions go 43315 to 33688, a 22.2% lead for the EPYC. Integer math lands at 162993 versus 120788, a 25.9% margin. Floating point math is closer but still favors the EPYC: 96446 versus 77955, a 19.2% lead. Random string sorting shows 71642 versus 45890, a 35.9% advantage.

The two most extreme results favor the EPYC by more than half. Find prime numbers scores 425 versus 183, a 56.9% difference. Physics scores 4938 versus 2122, a 57% difference. These are not marginal wins; they represent workloads where the EPYC’s core count and cache make it nearly twice as effective.

The Ryzen’s only wins are in single-thread tests. PassMark single-thread and singlethread both record 4691 for the Ryzen and 4119 for the EPYC, giving the Ryzen a 13.9% lead. That is a meaningful margin for single-core-bound software, but it is the only area where the desktop chip outperforms the server part.

For context, the Ryzen 7 9700F’s average benchmark score is 69996. Its nearest rivals include the AMD Ryzen 9 7940HX at 69875 (0.2% behind), the Intel Core i7-14700KF at 70163 (0.2% ahead), the AMD Ryzen 9 7950X at 69515 (0.7% behind), and the Intel Core i7-14700K at 69355 (0.9% behind). The EPYC 4484PX’s average score is 67822. Its nearest rivals are the AMD Ryzen Threadripper PRO 5955WX at 67868 (0.1% ahead), the Intel Xeon w5-3525 at 67673 (0.2% behind), the AMD EPYC 7352 at 68118 (0.4% ahead), and the Intel Core Ultra 9 275HX at 67469 (0.5% behind). Both chips sit at the 94th percentile overall, meaning they outperform the vast majority of CPUs in the database, but the Ryzen’s average is about 3.2% higher than the EPYC’s.

The Verdict

The AMD EPYC 4484PX is the clear choice for multi-threaded and data-intensive workloads. It wins 9 of 11 shared benchmarks, with leads from 19.2% to 57%. Its 12 cores, 24 threads, 128 MB of L3 cache, and 3D V-Cache slice make it far better suited for server, workstation, and heavily parallel compute tasks. The 57% lead in physics and 56.9% lead in prime number finding show how dominant it is in workloads that reward core count and cache. Its 120 W TDP and locked multiplier are acceptable trade-offs for that kind of throughput.

The AMD Ryzen 7 9700F is the better pick for single-thread-sensitive applications. Its 13.9% lead in single-thread performance is significant, and its higher memory bandwidth of 89.6 GB/s versus 83.2 GB/s gives it a slight edge in memory-bound single-thread tasks. It also has a higher average benchmark score of 69996 versus 67822, and it sits at the same 94th percentile. The Ryzen’s lower 65 W TDP, unlocked multiplier, and later release date make it a more flexible, efficient desktop part.

In practical terms, the choice depends on the workload. If the task is running a database server, compiling large projects, or processing scientific data, the EPYC 4484PX is the obvious winner. If the task is running a desktop with mostly single-threaded software, gaming-adjacent workloads, or applications that need the fastest possible single-core response, the Ryzen 7 9700F is the better fit. The data does not support a single universal winner; it supports two purpose-built CPUs with different strengths.
