AMD EPYC 9474F vs AMD Ryzen 9 6900HS Comparison

Head-to-Head Benchmarks

The benchmark data presents a stark, one-sided picture. Across every shared test, the AMD EPYC 9474F dominates the AMD Ryzen 9 6900HS by margins that are difficult to overstate. The EPYC 9474F wins all four head-to-head comparisons, with zero wins for the mobile Ryzen part.

The largest gap appears in Cinebench R23 multi-core, where the EPYC 9474F scores 86,790 against the Ryzen 9 6900HS’s 13,445. That is a delta of -84.5% from the perspective of the Ryzen part, meaning the EPYC delivers roughly six and a half times the multi-threaded rendering performance. In Cinebench R15 multi-core, the delta is -75.3% (8,748 vs 2,161), still a massive advantage but slightly narrower, suggesting the workload scaling favors the server chip even more as thread counts rise in the R23 test.

Single-core results are equally lopsided, though the gap is proportionally smaller. In Cinebench R23 single-core, the EPYC scores 12,252 versus 1,554 for the Ryzen, a delta of -87.3%. Cinebench R15 single-core shows a -80.1% delta (1,234 vs 245). Even in a purely single-threaded scenario, the EPYC’s higher base clock of 3.60 GHz and more modern Zen 4 architecture overcome any frequency advantage the Ryzen 9 6900HS might claim with its 4.90 GHz boost clock.

For context, the Ryzen 9 6900HS has an average benchmark score of 25,284, placing it at the 77th percentile of all CPUs. Its nearest rival, the Intel Core i5-13400F, scores 25,292 (0% delta), making them effectively tied. The EPYC 9474F, despite its overwhelming victory here, also sits at the 77th percentile with an average score of 25,103. Its closest competitor, the AMD Ryzen 7 7735HS, scores 25,147 (-0.2% delta). This means that while the EPYC crushes the Ryzen 9 in the head-to-head tests, its overall average benchmark score is similar because the broader benchmark suite includes workloads where its massive core count does not translate into proportional gains.

Architecture Differences

The two processors come from entirely different worlds within the AMD lineup. The Ryzen 9 6900HS is a mobile part built on the Zen 3+ architecture, codenamed Rembrandt, fabricated on TSMC’s 6 nm process. It packs 8 cores and 16 threads into a 35 W TDP, designed for thin-and-light laptops. The EPYC 9474F is a server/workstation chip using the Zen 4 architecture, codenamed Genoa, on TSMC’s 5 nm node. It scales to 48 cores and 96 threads with a 360 W TDP, aimed at datacenter workloads.

Cache configurations diverge sharply. The Ryzen 9 6900HS has 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The EPYC 9474F also has 64 KB of L1 per core, but doubles the L2 to 1 MB per core and expands shared L3 to a massive 256 MB. That 16x difference in L3 capacity is a primary driver of its performance in cache-sensitive server workloads.

Memory subsystems are another major differentiator. The Ryzen 9 6900HS supports dual-channel DDR5 with 76.8 GB/s of bandwidth and no ECC. The EPYC 9474F runs twelve-channel DDR5, delivering 460.8 GB/s — exactly six times the bandwidth — and supports ECC memory. The EPYC also offers PCIe Gen 5 with 128 lanes (CPU only), while the Ryzen 9 is limited to PCIe Gen 4 with 20 lanes. The EPYC’s transistor count is listed at 52,560 million across eight 72 mm² chiplets, whereas the Ryzen 9 uses a single 208 mm² die with no transistor figure provided.

The Ryzen 9 6900HS includes integrated Radeon 680M graphics; the EPYC 9474F has no integrated graphics at all. The EPYC was released on 2022-11-09 with a launch MSRP of $6780. The Ryzen 9 has no listed release date or MSRP. Both parts feature locked multipliers, and both are actively in production.

Where Each One Wins

Given the benchmark results, there is no workload category where the Ryzen 9 6900HS beats the EPYC 9474F in the shared tests. The EPYC wins every available comparison: Cinebench R15 and R23, both multi-core and single-core. The data simply does not support any scenario where the mobile chip comes out ahead.

That does not mean the Ryzen 9 is useless — it wins on practical grounds that the benchmarks do not capture. Its 35 W TDP makes it suitable for battery-powered laptops, where the EPYC’s 360 W TDP would be physically impossible to cool or power. The integrated Radeon 680M graphics eliminate the need for a discrete GPU in light gaming or media tasks. Its 4.90 GHz boost clock and 6 nm process suggest strong transient performance for bursty, single-threaded workloads, even if the Cinebench single-core numbers favor the EPYC due to architectural generational gains.

The EPYC 9474F is the clear winner for any compute-heavy, multi-threaded, or memory-bandwidth-bound task. The 460.8 GB/s of memory bandwidth, 256 MB of L3 cache, and 48 physical cores make it ideal for virtualization, large-scale data processing, scientific simulation, and heavy rendering. The ECC memory support adds reliability for long-running server workloads. The PCIe Gen 5 with 128 lanes allows extensive I/O expansion for GPUs, NVMe storage, and network cards.

The Ryzen 9 6900HS’s strengths are elsewhere. In the 3DMark tests (not shared with the EPYC, but present in its own benchmark list), it scores 6,963 in 16-thread and 6,955 in max-thread tests, with a single-thread score of 915. These numbers suggest balanced performance for a mobile part. Its PassMark scores are more revealing: 86,449 in integer math, 48,239 in floating-point math, and 23,152 in multithread. These are respectable for a 35 W chip, but none approach the EPYC’s raw output.

The practical answer is that the Ryzen 9 wins in portability, power efficiency, and integrated graphics capability. The EPYC wins in every raw performance metric measured.

The Verdict

The data dictates a simple conclusion: choose the AMD EPYC 9474F if you need maximum compute throughput and have the power and cooling budget to support it. Its 84.5% lead in Cinebench R23 multi-core and 87.3% lead in single-core are decisive. The 48 cores, 96 threads, 256 MB L3 cache, and twelve-channel memory make it the only choice for server racks, high-performance workstations, or any environment where the 360 W TDP is acceptable.

Choose the AMD Ryzen 9 6900HS if your priority is mobility and efficiency. It cannot compete in any shared benchmark, but its 35 W TDP and integrated Radeon 680M graphics make it viable for laptops where the EPYC physically cannot exist. The Ryzen 9’s 77th percentile overall ranking and near-tie with the Intel Core i5-13400F (0% delta) show it is a competent mid-range performer in its own right.

The EPYC 9474F’s average benchmark score of 25,103 is actually slightly lower than the Ryzen 9’s 25,284, despite its overwhelming head-to-head wins. This paradox stems from the benchmark suite composition: the EPYC’s scores are drawn from a different, smaller set of tests that do not include the 3DMark or PassMark workloads where the Ryzen 9 accumulates points. In the shared tests, the EPYC is categorically superior.

For a buyer, the question is not which is faster — that is settled. The question is which fits the use case. The EPYC is a datacenter powerhouse. The Ryzen 9 is a premium mobile chip. Neither competes in the other’s domain.
