AMD EPYC 4464P vs AMD Ryzen 9 7950X3D Comparison

The AMD Ryzen 9 7950X3D and AMD EPYC 4464P are both Zen 4 parts built on the same 5nm TSMC process, but they are aimed at entirely different buyers. The Ryzen 9 7950X3D is a desktop flagship with 16 cores and a 3D V-Cache slice, while the EPYC 4464P is a server/workstation chip with 12 cores and a much lower 65W TDP. The data shows a clear split: the 7950X3D wins 12 of 15 head-to-head benchmarks, often by large margins in multi-threaded and math-heavy workloads, but the EPYC 4464P counters with massive single-core wins in Cinebench and a lower launch MSRP. If you need raw desktop throughput and cache-heavy performance, the 7950X3D is the pick. If you need efficient server-grade single-core speed and ECC reliability in a lower-power envelope, the EPYC 4464P is the data-supported choice.

The Verdict

The Ryzen 9 7950X3D is the clear winner for desktop enthusiasts and content creators who value multi-threaded muscle and large cache. Benchmark results show it leads the EPYC 4464P by 47.4% in Cinebench R15 multi-core and by 75.9% in Passmark physics, with 12 total wins out of 15 head-to-head tests. Its average benchmark score of 65914 puts it in the 93rd percentile of all CPUs, and it sits within 0.3% of the Intel Core 9 273PQE (avg score 66099), which is its closest rival.

The EPYC 4464P is the pick for server/workstation workloads where single-core performance and power efficiency matter more than core count. It wins Cinebench R23 multi-core by 9.8% (40215 vs 36291) and crushes the 7950X3D in single-core tests, posting a 63.8% higher Cinebench R23 single-core score (5677 vs 2053) and a 43% higher R15 single-core score (572 vs 326). It also has a 65W TDP versus 120W, making it far easier to cool in dense server environments. Its launch MSRP is $429, compared to $699 for the 7950X3D.

Do not buy the 7950X3D if single-core speed is your primary metric; the EPYC 4464P is decisively ahead there. Do not buy the EPYC 4464P if you need maximum multi-threaded throughput; the 7950X3D wins most of those tests, and its 16 cores/32 threads outmatch the EPYC’s 12/24 configuration.

Architecture Differences

Both processors share the same Zen 4 architecture, the Raphael codename, and the 5nm TSMC process node. They are built on the same 2x 71 mm² die size, but the transistor counts differ: the 7950X3D packs 17,840 million transistors with a 128 MB shared L3 cache plus a 1x 64MB 3D V-Cache slice, while the EPYC 4464P has 13,140 million transistors and a 64 MB shared L3 cache with no V-Cache. This means the 7950X3D effectively doubles the L3 capacity, which explains its dominance in cache-sensitive workloads like data compression and random string sorting.

The EPYC 4464P compensates with more PCIe lanes: 28 Gen 5 lanes (CPU only) versus 24 on the 7950X3D. Both support DDR5 memory on a dual-channel bus with 83.2 GB/s bandwidth, and both have ECC memory support and integrated Radeon Graphics. The key architectural split is the 3D V-Cache on the 7950X3D versus the EPYC’s higher boost clock efficiency per core—though both share the same 5.40 GHz boost, the EPYC’s base clock is 3.70 GHz versus 4.20 GHz on the 7950X3D. The 7950X3D also has an unlocked multiplier, while the EPYC 4464P is locked, reflecting its server positioning.

Head-to-Head Benchmarks

The 7950X3D dominates the Passmark suite. It leads by 36.7% in data compression (784993 vs 574304), 31.5% in data encryption (47100 vs 35816), 48.7% in extended instructions (58515 vs 39359), and 44.3% in find prime numbers (495 vs 343). Floating-point math shows a 40.1% lead (130403 vs 93090), integer math is 33.5% ahead (214089 vs 160410), and multithread is 31.3% higher (62383 vs 47514). Physics is the biggest gap at 75.9% (5053 vs 2873), and random string sorting is 32.2% ahead (92784 vs 70200). These are not marginal differences; the 7950X3D is outright faster in nearly every compute-heavy task.

The EPYC 4464P wins the Cinebench single-core tests decisively. In R15 single-core, it scores 572 versus 326, a 43% advantage. In R23 single-core, it scores 5677 versus 2053, a 63.8% advantage. It also wins R23 multi-core with 40215 versus 36291, a 9.8% lead, despite having fewer cores. The two chips tie exactly on Passmark single-thread (both 4146), so the EPYC’s single-core edge is specific to Cinebench’s rendering workload, not a universal trait.

Where Each One Wins

The 7950X3D wins in every Passmark category tested: data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, physics, and random string sorting. This makes it the superior choice for desktop productivity, scientific computing, and any workload that leverages large L3 cache or heavy math. Its 12 head-to-head wins out of 15 tests confirm it is the faster overall processor for general compute.

The EPYC 4464P wins in Cinebench R15 single-core, R23 single-core, and R23 multi-core. This makes it the better option for rendering workloads that are single-threaded or lightly threaded, and its 65W TDP versus 120W makes it far more energy-efficient for server racks. Its higher PCIe lane count (28 vs 24) also gives it an edge in I/O-heavy server configurations. If your application is Cinebench-style rendering or you need low-power ECC server performance, the EPYC 4464P is the data-backed winner. For everything else, the 7950X3D is the stronger performer.
