AMD EPYC 9474F vs AMD Ryzen 5 PRO 6650H Comparison

The Verdict

The data presents a stark contrast between two very different AMD processors. The AMD EPYC 9474F is the dominant performer in every single recorded benchmark, decisively winning all four head-to-head comparisons. For workloads that can scale across many cores, the EPYC 9474F is the clear choice. The Ryzen 5 PRO 6650H, while far behind in raw throughput, serves a completely different purpose as a mobile processor with integrated graphics. The database shows the EPYC 9474F delivering 82.3% higher scores in Cinebench R15 multi-core, 80.9% higher in single-core, 89% higher in Cinebench R23 multi-core, and 88% higher in single-core. These are not marginal gains, they are massive differences that reflect the fundamental design goals of each chip. The EPYC 9474F is for server and workstation environments where multi-threaded performance is paramount. The Ryzen 5 PRO 6650H is for mobile devices where power efficiency and integrated graphics matter more than raw compute.

Architecture Differences

The architectural gap between these two processors is substantial. The Ryzen 5 PRO 6650H uses the Zen 3+ architecture with the codename Rembrandt, while the EPYC 9474F uses the newer Zen 4 architecture with the codename Genoa. This generational difference is visible in the process node: the Ryzen uses a 6 nm node from TSMC with a die size of 208 mm², while the EPYC uses a 5 nm node with a die size composed of 8x 72 mm² chiplets. The EPYC also has a much higher transistor count at 52,560 million, which enables its massive core count.

Cache hierarchies differ significantly. Both have 64 KB of L1 cache per core, but the L2 cache doubles from 512 KB per core on the Ryzen to 1 MB per core on the EPYC. The L3 cache is dramatically different: the Ryzen has 16 MB shared, while the EPYC has 256 MB shared. That is a 16x difference in total L3 capacity, which directly impacts workloads that rely on large working sets.

The EPYC 9474F also includes features the mobile chip lacks: ECC memory support and a server-class twelve-channel memory bus. The Ryzen 5 PRO 6650H features integrated graphics via the Radeon 660M, while the EPYC has no integrated graphics at all. PCIe connectivity also differs, with the EPYC offering Gen 5 with 128 lanes versus the Ryzen's Gen 4 with 20 lanes. These are not just specification differences, they reflect entirely different market positions: mobile computing versus server infrastructure.

Specification Differences

The two processors differ on nearly every key specification. The Ryzen 5 PRO 6650H has 6 cores and 12 threads, while the EPYC 9474F has 48 cores and 96 threads. Base clocks are 3.30 GHz versus 3.60 GHz respectively, but boost clocks reverse the order: the Ryzen reaches 4.50 GHz while the EPYC maxes out at 4.10 GHz. TDP is a major separator: 45 watts for the Ryzen versus 360 watts for the EPYC, an 8x difference that explains the power envelope disparity.

Memory support shows the server chip's advantage. The Ryzen uses dual-channel DDR5 with 76.8 GB/s bandwidth, while the EPYC uses twelve-channel DDR5 with 460.8 GB/s bandwidth. The EPYC supports ECC, the Ryzen does not. PCIe lanes also differ: Gen 4 with 20 lanes for the Ryzen, Gen 5 with 128 lanes for the EPYC. The Ryzen includes the Radeon 660M integrated GPU, while the EPYC has none. Sockets are incompatible: AMD Socket FP7 for the Ryzen, AMD Socket SP5 for the EPYC. Release dates are also distinct: the Ryzen launched on 2022-04-18, the EPYC on 2022-11-09. The EPYC has a launch MSRP of $6780, and both are currently active in production.

Head-to-Head Benchmarks

The recorded benchmarks show a total sweep for the EPYC 9474F across all four head-to-head tests. The smallest margin is in Cinebench R15 single-core, where the EPYC scores 1234 against the Ryzen's 236, a delta of 80.9%. Even in single-threaded performance, the server chip is dramatically faster, which is notable given the Ryzen's higher boost clock. The architecture's IPC advantage and larger cache likely explain this.

In Cinebench R15 multi-core, the EPYC scores 8748 versus 1550, a delta of 82.3%. This test scales with core count, and the 8x core advantage of the EPYC translates into a 5.6x score advantage. The gap widens further in Cinebench R23 multi-core: 86790 versus 9561, a delta of 89%. This shows that the EPYC's advantage grows as the workload becomes more demanding and better utilizes all available resources. The single-core R23 test shows 12252 versus 1471, a delta of 88%, indicating that the EPYC's per-core performance is also far superior despite the lower boost clock.

The win count is unambiguous: 4 wins for the EPYC, 0 wins for the Ryzen. The average benchmark scores confirm the trend: the EPYC averages 25103 across all recorded tests, while the Ryzen averages 24364. The percentile rankings are close (77th versus 76th percentile of all CPUs), but this is because the Ryzen's benchmark set includes many different tests, not just the head-to-head ones.

Where Each One Wins

The EPYC 9474F wins in every measurable performance category in this database. Its multi-core scores are on another level, with Cinebench R23 multi-core at 86790, nearly 9x the Ryzen's 9561. This makes it the obvious choice for server workloads, virtualization, database processing, scientific computing, and any application that can utilize 96 threads. The twelve-channel memory bandwidth of 460.8 GB/s further supports these demanding environments, as does the 256 MB L3 cache and ECC memory support. The 128 PCIe Gen 5 lanes also enable extensive I/O expansion for storage arrays and network interfaces.

The Ryzen 5 PRO 6650H, despite losing all head-to-head benchmarks, has clear strengths in its own domain. Its 45 watt TDP makes it suitable for mobile devices, and its integrated Radeon 660M graphics eliminate the need for a separate GPU in many laptops. The 20 PCIe Gen 4 lanes are adequate for a mobile system, and the 76.8 GB/s memory bandwidth is reasonable for a dual-channel configuration. Its 6 cores and 12 threads are enough for everyday productivity tasks, and its higher boost clock of 4.50 GHz provides snappy single-threaded response in lighter workloads.

The data suggests that these processors should never be compared as alternatives. The EPYC 9474F is a 48-core, 360-watt server monster with a launch MSRP of $6780, designed for rack-mounted density and maximum throughput. The Ryzen 5 PRO 6650H is a 6-core, 45-watt mobile chip designed for battery life and portability. The benchmark results reflect this fundamental divide: the EPYC dominates raw compute, while the Ryzen offers the only integrated graphics option and a fraction of the power draw. Users needing server-grade performance should choose the EPYC 9474F without hesitation. Users needing a mobile processor with integrated graphics should look to the Ryzen 5 PRO 6650H, accepting that its performance is far below the server part in every recorded test.
