AMD made a big impression at CES 2023 by introducing three new high-end Zen 4-based Ryzen 7000X3D processors for its AM5 platform. AMD’s 3D V-Cache technology equips the AMD Ryzen 9 7950X3D, Ryzen 7 7900X3D, and Ryzen 7 7800X3D. With this technology, an additional SRAM chip 3D-stacks vertically on top of the processor, increasing the L3 cache capacity by 64MB. This technology was first used in the first-generation Ryzen 7 5800X3D model. Its goal is to give gamers huge speed boosts, but it does not affect productivity tasks.
The new chipsets come with 8, 16, and 24 cores, a significant improvement over the single Ryzen 7 5800X3D model released with the first generation of chips. AMD claims that these new chips will beat Intel’s fastest gaming chip by up to 24% in some games and offer “explosive generational performance gains.” The 7000 chips will be on the market in February, but there is no price information yet.
AMD Ryzen 9 7950X3D
The flagship AMD Ryzen 9 7950X3D has 16 cores and 32 threads, a new high for 3D V-Cache-equipped chips. This chip is essentially a Ryzen 9 7950X with an additional L3 cache chipset and additional tuning. It has 144MB of cache in total, 128MB of which is the gaming-enhancing L3 cache. AMD has given the 3D V-Cache processors a minimum TPD of 120W and a maximum PPT of 162W. This is less than the standard 170W/230W threshold for the 7950X.
Because of the additional cache chiplet, operating temperatures may be slightly higher. But with the new CPU models, AMD has made boost speeds much faster. For example, the 7950X3D can boost to an impressive 5.7 GHz, much faster than the 5800X3D’s peak of 4.5 GHz and the same as the 7950X.

AMD Ryzen 7 7900X3D
The Ryzen 7 7900X3D has 12 cores and 24 threads, and a clock speed of 5.6 GHz, the same as the standard 7900X. It has 104MB of cache, with 96MB dedicated to L3. The final chip in the lineup, the Ryzen 7 7800X3D, has 8 cores and 16 threads and a clock speed of 5.5 GHz. It has 72MB of cache, 64MB of which is L3.
AMD has shared some performance benchmarks, but as with all third-party tests, they should be taken with a grain of salt. In gaming, the 7950X3D is anywhere from 13% to 24% faster than the Intel Core i9-13900K, and in productivity, it is anywhere from 4% to 52% faster. In various titles, the 7800X3D is anywhere from 21% to 30% faster than the 5800X3D.
However, it is worth noting that these benchmarks include a few esports titles, and some games will either benefit less or not from the extra cache.
AMD Ryzen 7000X3D
Finally, AMD’s new Zen 4 Ryzen 7000X3D processors, with their revolutionary 3D V-Cache technology and impressive performance gains, are poised to shake up the high-end CPU market. The AMD Ryzen 9 7950X3D, Ryzen 7 7900X3D, and Ryzen 7 7800X3D are all scheduled to be released in February, with no pricing information yet available. These chips outperform the previous-generation 5800X3D model with faster boost speeds, more cores and threads, and more cache.
While third-party performance benchmarks should always be taken with a grain of salt, AMD claims that these chips offer “explosive generational performance gains” and can outperform Intel’s fastest gaming chip by up to 24% in some games. When these chips are released, it will be interesting to see how they compare to the competition and whether they can keep AMD at the top of the CPU market.
