AMD EPYC 9474F vs AMD Ryzen 7 6800H Comparison

The AMD Ryzen 7 6800H and AMD EPYC 9474F occupy opposite ends of the processor spectrum, yet benchmark aggregation places them within 0.4% of each other in average score. The Ryzen 7 6800H is a 45 W mobile part with 8 Zen 3+ cores, while the EPYC 9474F is a 360 W server flagship with 48 Zen 4 cores. The data shows a clear split: the EPYC dominates every shared multi-threaded and single-threaded test, but the Ryzen’s overall average is buoyed by a broader benchmark suite that includes workloads where the server chip has no recorded results.

Head-to-Head Benchmarks

The head-to-head comparison is lopsided. Four Cinebench tests are shared, and the AMD EPYC 9474F wins all four by massive margins. In Cinebench R23 multi-core, the EPYC scores 86,790 against the Ryzen’s 13,094, a delta of -84.9% from the mobile chip’s perspective. That is a 6.6x raw score advantage, reflecting the EPYC’s 48 cores and 96 threads versus the Ryzen’s 8 cores and 16 threads. The single-core gap is similarly stark: Cinebench R23 single-core shows the EPYC at 12,252 and the Ryzen at 1,542, a -87.4% delta. The EPYC’s Zen 4 architecture at a 3.60 GHz base clock simply outpaces the Zen 3+ design in the Ryzen, even though the Ryzen boosts higher at 4.70 GHz versus 4.10 GHz.

Cinebench R15 tells the same story. In multi-core, the EPYC posts 8,748 versus the Ryzen’s 2,136, a -75.6% delta. Single-core R15 sees the EPYC at 1,234 and the Ryzen at 242.5, a -80.3% delta. Notably, the Ryzen has no R20 results in the shared set, while the EPYC scores 36,451 multi-core and 5,145 single-core in that test. The EPYC wins all four head-to-head matchups, giving it a 4-0 record. The Ryzen’s wins, if any, would have to come from tests not shared in this dataset.

The broader benchmark suites reveal why the average scores converge. The Ryzen 7 6800H has 23 recorded benchmarks, including 3DMark, Geekbench, and PassMark tests. Its PassMark multi-thread score is 23,060, and its Geekbench multi-core is 9,642. The EPYC 9474F has only six recorded benchmarks, all Cinebench variants. This means the Ryzen’s average of 25,201 is computed over a wider range of workloads, while the EPYC’s average of 25,103 relies solely on its Cinebench dominance. The nearest rival data confirms the parity: the Ryzen’s closest rival is the AMD Ryzen 7 7735HS at 25,147 (0.2% delta), and the EPYC’s closest rival is the same 7735HS at -0.2%. The two processors are listed as each other’s rivals, with the Ryzen at 0.4% above the EPYC and the EPYC at -0.4% below the Ryzen.

The Verdict

The data is unambiguous for raw compute: the AMD EPYC 9474F is the superior processor in every shared benchmark. Its Cinebench R23 multi-core score of 86,790 is 84.9% higher than the Ryzen’s 13,094, and its single-core lead is 87.4%. Anyone needing maximum multi-threaded throughput for server or workstation workloads should pick the EPYC 9474F. It also offers ECC memory support, a twelve-channel memory bus with 460.8 GB/s bandwidth, and 128 PCIe Gen 5 lanes, all features absent from the Ryzen.

However, the Ryzen 7 6800H is not without merit. It is a mobile processor with a 45 W TDP, integrated Radeon 680M graphics, and a 76.8 GB/s dual-channel memory bus. It targets laptops and compact systems where the EPYC’s 360 W TDP and Socket SP5 requirement are non-starters. The Ryzen’s average benchmark score of 25,201 actually edges out the EPYC’s 25,103 by 0.4%, driven by its diverse PassMark and Geekbench results. For users who need a capable all-rounder in a portable chassis, the Ryzen is the only viable option here. The EPYC has no integrated graphics, no mobile form factor, and a launch MSRP of $6780, while the Ryzen has no listed MSRP.

The verdict hinges on context. The EPYC wins every performance metric in the shared tests, but the Ryzen wins on versatility and efficiency metrics that the EPYC cannot match. The EPYC’s 48 cores and 256 MB of L3 cache make it a server powerhouse, while the Ryzen’s 8 cores and 16 MB of L3 cache make it a mobile workhorse. Neither is a substitute for the other.

Architecture Differences

The two processors are built on different generations of AMD’s core designs. The Ryzen 7 6800H uses Zen 3+ architecture, codenamed Rembrandt, fabricated on TSMC’s 6 nm process with a die size of 208 mm². The EPYC 9474F uses Zen 4, codenamed Genoa, on TSMC’s 5 nm process with a die size of 8x 72 mm² and 52,560 million transistors. The process node shrink from 6 nm to 5 nm gives the EPYC a density advantage, though the Ryzen’s monolithic die is simpler than the EPYC’s multi-chiplet design.

Core counts differ by a factor of six. The Ryzen has 8 cores and 16 threads, while the EPYC has 48 cores and 96 threads. The EPYC’s base clock of 3.60 GHz is higher than the Ryzen’s 3.20 GHz, but the Ryzen’s boost clock of 4.70 GHz exceeds the EPYC’s 4.10 GHz. This explains why the EPYC still wins single-core tests: its Zen 4 architecture delivers higher instructions-per-clock, overcoming the Ryzen’s higher boost frequency.

Cache hierarchies are vastly different. Both have 64 KB of L1 per core, but the Ryzen has 512 KB of L2 per core while the EPYC has 1 MB per core. The L3 cache difference is stark: the Ryzen has 16 MB shared, while the EPYC has 256 MB shared. That 16x L3 advantage helps the EPYC in server workloads with large working sets. Memory support also diverges: both support DDR5, but the Ryzen uses a dual-channel bus with 76.8 GB/s bandwidth, while the EPYC uses a twelve-channel bus with 460.8 GB/s bandwidth. The EPYC also supports ECC memory; the Ryzen does not. PCIe connectivity favors the EPYC with Gen 5 and 128 lanes, versus the Ryzen’s Gen 4 and 20 lanes.

The Ryzen includes integrated Radeon 680M graphics, making it a complete APU. The EPYC has no integrated graphics, relying on discrete GPUs or server management controllers. The Ryzen uses AMD Socket FP7, a mobile socket, while the EPYC uses AMD Socket SP5, a server socket. The EPYC is a 360 W part, the Ryzen a 45 W part. The EPYC’s release date is listed as 2022-11-09, while the Ryzen’s release date is not provided. Both are marked as Active in production.

Where Each One Wins

The AMD EPYC 9474F wins in every shared benchmark category. It dominates multi-threaded Cinebench R15 and R23, single-threaded R15 and R23, and all four head-to-head matchups. Its 48 cores and 96 threads make it the clear choice for server-side rendering, virtualization, heavy database workloads, and any compute task that scales with core count. The 256 MB L3 cache and 460.8 GB/s memory bandwidth are tailor-made for large datasets and high-concurrency environments. The EPYC also wins on I/O capability with 128 PCIe Gen 5 lanes, enabling massive storage and networking arrays. Its ECC memory support adds reliability for mission-critical applications.

The AMD Ryzen 7 6800H wins on portability and integration. With a 45 W TDP, it can fit in thin-and-light laptops, while the EPYC’s 360 W TDP requires a server chassis. The Ryzen’s integrated Radeon 680M graphics eliminate the need for a discrete GPU in basic display tasks, which the EPYC cannot do. The Ryzen also wins on clock speed: its 4.70 GHz boost exceeds the EPYC’s 4.10 GHz, though this does not translate to single-core benchmark wins due to architectural differences. The Ryzen’s average benchmark score of 25,201 is 0.4% higher than the EPYC’s, thanks to its broader test suite covering 3DMark, Geekbench, and PassMark workloads.

In practical terms, the Ryzen wins for mobile productivity, light gaming, and everyday computing. The EPYC wins for enterprise-class computing where raw throughput and memory capacity are paramount. The Ryzen 7 6800H’s nearest rival is the AMD Ryzen 7 7735HS at 25,147 (0.2% delta), while the EPYC 9474F’s nearest rival is the AMD Ryzen 5 8400F at 25,005 (0.4% delta). These rivalries show that both processors sit in competitive performance bands, but they are not interchangeable products. The choice is dictated by platform, power budget, and workload type, not by raw benchmark numbers alone.
