AMD Ryzen 7 7800X3D vs AMD Ryzen 7 8705G: Comparison
Ryzen 7 7800X3D vs Ryzen 7 8705G l3 cache compared
The gap that matters here is l3 cache: Ryzen 7 7800X3D 96 MB against Ryzen 7 8705G 16 MB, which puts Ryzen 7 7800X3D 83% ahead. Unlocked multiplier is not the same on both, No on the Ryzen 7 7800X3D versus Yes on the Ryzen 7 8705G. They differ on base power too, 120 W on the Ryzen 7 7800X3D versus 45-65W on the Ryzen 7 8705G. They differ on memory type too, DDR5-5200 on the Ryzen 7 7800X3D versus DDR5, 2-Channel on the Ryzen 7 8705G.
Who each one is for
Take the Ryzen 7 7800X3D for gaming-focused desktop builds wanting the strongest real-world frame rates available from AMD's Zen 4 lineup. It is not the one for buyers prioritizing multi-threaded productivity work, non-3D chips with more cores or the newer Zen 5 lineup offer more raw throughput. The Ryzen 7 8705G is the one to take for mainstream desktop builds and everyday productivity, though it is the wrong buy for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. Our rating of the Ryzen 7 7800X3D (8.8/10): the AMD Ryzen 7 7800X3D is a superb gaming CPU, its 3D V-Cache delivering top-tier frame rates at low power draw.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and p-core base clock read the same on both, so those are not worth weighing. They match on 5 further specifications as well.
Frequently asked questions
Do the Ryzen 7 7800X3D and Ryzen 7 8705G differ on p-core boost clock?
