AMD says the 9950X3D should be around 8 percent faster on average than the previous 7950X3D, based on benchmarks run on 40 games at 1080p. The gaming performance should be similar

AMD has a used 3D V-Cache a few times now as a way to boost gaming performance on CPUs. So what happens when AMD puts 3D V-Cache on its very best Ryzen 9000-series CPUs to date? The answer is the Ryzen 9 9900X3D and 9950X3D.

"The AMD Ryzen 7 9800X3D is extremely powerful in games, which makes it easier to recommend than other recent processors like the Intel Core Ultra 9 285K or Ryzen 9 9900X. Especially if you’re building a rig with a powerful graphics card, the 9800X3D is going to be the best way to get the most performance out of whichever GPU you pair it with."
