AMD’s Ryzen 7000 desktop processors with enhanced 3D V-Cache will be available for purchase on February 28th, the company announced today. The rollout will start with the 12 core Ryzen 9 7900X3D and 16 core Ryzen 9 7950X3D starting at $599 and $699 respectively. A cheaper model, the 8-core Ryzen 7 7800X3D, is available for $449 but won’t launch until April 6th.
All of these CPUs are successors to the original Ryzen 7 5800X3D and have similar pitches. AMD is stacking an extra 64MB of L3 cache on top of the regular Ryzen 7000 CPUs. This greatly improves performance for software that is particularly sensitive to cache size and speed (such as games).
These prices are actually not much higher than the launch prices of the original Ryzen 7000 CPUs back in August. However, the price has come down significantly since then. Currently, the 7950X typically costs between $550-$600, with non-X-series CPUs like the Ryzen 7 7700 and Ryzen 9 7950 even cheaper. The price of the X3D chip will eventually come down as well, but it’s still significantly more expensive than the version without the extra cache.
AMD seems to have fixed some of the limitations the original 5800X3D had when it came out. was added. The X3D series CPUs run at lower clock speeds than their equivalent X series CPUs, but by a smaller margin. The CPU also supports memory overclocking as well as some limited performance tuning via Precision Boost Overdrive and Curve Optimizer features.
However, the X3D chip still doesn’t support the typical overclocking features available on the rest of the Ryzen CPUs, nor does it support changing the CPU’s default 120W TDP limit. This can further limit performance on 12- and 16-core CPUs for cache-agnostic apps. The Ryzen 5800X3D also ran hotter than his other Ryzen CPUs, but the Ryzen 7000’s baseline temps are already pretty high, so we’ll have to test that for comparison.
AMD has said the new CPUs require socket AM5 motherboards with updated BIOS and chipset drivers, and the company said:[s] For best performance, use at least a 280mm all-in-one liquid cooler. ”
