Ryzen 7000 desktop processors with 3D solid-state memory and 3D cache from AMD will be available for purchase on February 28. Announce today. The rollout will start with the 12-core Ryzen 9 7900X3D and the 16-core Ryzen 9 7950X3D, which will start at $599 and $699, respectively. The cheaper eight-core Ryzen 7 7800X3D model will be available for $449 but won’t launch until April 6th.
All of these CPUs are successors to the original Ryzen 7 5800X3D, and their sales are similar. AMD stacks an extra 64MB of L3 cache on top of regular Ryzen 7000 CPUs, which can provide significant performance for programs (like games) that are particularly sensitive to cache sizes and speeds.
These prices aren’t much higher than the launch prices of the original Ryzen 7000 CPUs in August — the 7950X3D has the same launch price as the 7950X, and the 7900X3D and 7800 X3D are only $50 more expensive than their counterparts. But prices have fallen a lot since then; 7950X costs normally Between $550 and $600 nowAnd Non-X Series CPUs such as the Ryzen 7 7700 and Ryzen 9 7950 Even cheaper. X3D chips will eventually come down in price as well, but they’re still much more expensive than versions without additional cache.
It appears that AMD has fixed some of the limitations that the original 5800X3D had when it was introduced. Notably, there are now 12- and 16-core options for people who use their computers for things other than gaming. X3D Series CPUs still run at lower clock speeds than comparable X Series CPUs, but the gap is slightly smaller. CPUs support some limited performance tweaking via the Precision Boost Overdrive and Curve Optimizer features, as well as memory overclocking.
But the X3D chips still don’t support the typical overclocking features available in the rest of the Ryzen CPUs, nor do they support changing the default 120 W TDP limits for CPUs. This can limit the performance of 12- and 16-core CPUs in applications that don’t care about cache—the 7900X and 7950X have a default TDP of 170W, which allows them to run faster for longer. The Ryzen 5800X3D also ran hotter than other Ryzen CPUs, but the Ryzen 7000’s baseline temperatures are already fairly warm, so we’ll need to test it for comparison.
AMD says the new CPUs will require a socket AM5 motherboard with an updated BIOS and chipset driver, and the company also recommends “[s] Using at least 280mm all-in-one liquid cooler for best performance. “
