Be leery of the 7900X3D, it doesn’t have a full suite of the same cache the 7800/7950X3D chips. It’s kind of a goofy cousin of the others and is better to skip it, hence the price crashed through the floor on them. Seems they’ve been playing with the 7800’s pricing as the newest chips like the 9900 isn’t as fast in gaming. The 7950X3D is solid but it takes a little core parking to be as streamlined as the 7800X3D in gaming applications. However in productivity it excels far better.
The newest 9 series is going through its HEY I’M NEW! phase just like GPU’s do. Where they release Card A, then A-ti, then A-ti-Super. 9xxx X3D chips are going to probably be the next monster, but they don’t just release those right away, could be a while.
In the interim apparently they’re jacking up the prices on the 7800X3D. It’s still the essential ‘console’ version of the CPU. All business, everything is there to do one thing with no fuss and streamlined to do it.
Be VERY careful with AMD ram. Usually g.skill is highly AMD centric. Make sure it’s 100% AMD EXPO friendly ram. Corsair does make AMD ram but they lean heavily to XMP timings in the overall catalog. The 7800/7950X3D chips kind of orbit around DDR5 6000 CL30 RAM being ideal. Corsair does in fact have a set.
All said and done, doesn’t look like AMD has any current 7800X3D ‘upgrade’, except in the pricing.
Now more than ever though, waiting out the release is probably a good idea before committing to all the components, particularly GPU.
